The present invention relates to a digital still video camera as well as to an image data output system for a digital still video camera, and more particularly to a digital still video camera as well as to an image data output system for a digital still video camera for outputting image data for the digital still video camera having a function for data transaction to recording paper through an image forming apparatus.
The present invention also relates to a digital still video camera in which an image and voice in combination can be recorded, and more particularly to a digital still video camera in which the operability, workability, and convenience are improved by making use of a function for inputting voices more effectively. The present invention also relates to a frame for data relay for a digital still video camera as well as to a data transfer system for a digital still video camera, and more particularly to a frame for data relay for a digital still video camera as well as to a data transfer system for a digital still video camera in which the convenience thereof is improved when data is transferred between the digital still video camera and external device.
The present invention also relates to a digital still video camera for photographing an image and recording the image in a recording medium such as a memory card or the like, and more particularly to a digital still video camera always recording the photographed image in a recording medium without reducing a quantity of information for a main object for a photo.
The present invention also relates to a digital still video camera for recording at least photographed image in a recording medium, and more particularly to a digital still video camera for reporting a residual memory space of the recording medium with voices.
The present invention also relates to a digital still video camera for photographing an image and recording the image in a recording medium such as a memory card or the like, and more particularly to a digital still video camera in which a mask for identifying a photographed image area according to video which a user wants to record is selected, a form of the photographed image to be stored in the storage medium can freely be changed, and a number of pieces of video that can be stored in the storage medium is made to a maximum without degrading the quality of the recorded image, whereby the storage medium can effectively be utilized.
At first, conventionally it is required an image data output system for a digital still video camera as shown in
For instance, FIG. 59A and
FIG. 59C and
It should be noted that, in FIG. 59B and
Secondarily, in recent years the digital still video cameras have come to incorporate multiple and versatile functions, and there have been developed various types of recording mode including, in addition to a still picture mode for recording a photographed image as a still picture, a successively photographing mode for successively recording still pictures, a voice mode for recording voices, a still picture+voice mode for simultaneously recording a still picture and voices, a moving picture mode for recording moving pictures like that in a video camera, a moving picture+voice mode for simultaneously recording moving pictures and voices, and a character mode for clearly recording characters or the like, or some other modes.
As a step for making a video still video camera more versatile, there is provided an operation mode such as a communicating function for fetching image data as well as voice data each photographed by the digital still video camera into external device such as a computer or the like.
Conventionally, in this type of digital still video camera in which image data and voice data in combination can be recorded, the inputted voice data is recorded using a voice compression technology. Also a listening method is used for regeneration, identification, and edit of the recorded voice data like in a case of a personal computer or a tape recorder.
Thirdly, as a system of transferring data between devices based on the conventional technology, a wire communication system for connecting devices to each other with a cable has generally been employed. However, radio communication making use of infrared rays is going to be standardized in order to respond to such users' request that they want to do data transfer without preparing a cable or the like.
There is the IrDA (Infrared Data Association) as a group for promoting this standardization. In the radio communication between devices according to this radio communication system, as shown in
In order to give flexibility to a potential relation between the devices, as shown in
On the other hand, a recording capability of the digital still video camera has remarkably progressed, so that it is now possible to execute various types of recording for recording not only still pictures but also moving pictures, and voices, or a mixture of moving pictures+voices or the like. An IC card enabling a high-speed read/write of data is mainly used for recording. To fetch this recorded data into equipment such as a personal computer or the like, a dedicated radio communication function or an IC card reader is required.
For this reason, if a radio communication function based on the IrDA standard is incorporated in the digital still video camera, communications between devices each having the radio communication function based on the IrDA standard can be made easier, which makes it possible to improve the convenience of use of a digital still video camera.
Fourthly, as a digital still video camera based on the conventional technology, there is the one disclosed, for instance, in Japanese Patent Laid-Open Publication No. HEI 4-332281 under the title of “Electronic camera and image signal compressing device”. This camera comprises a compressing means for subjecting an image signal obtained by an image pickup device to compression processing and an object distance detecting means for detecting a distance between a object and the camera, and adjusts a compression rate according to an output from said object distance detecting means. Namely, by setting the compression rate according to a scene to be photographed if necessary, an average compression rate of an image can be made higher and reduction of the memory space required for one screen can be achieved, so that a photographer can take pictures satisfying the photographer's desire.
In the “Electronic still camera” disclosed in Japanese Patent Laid-Open Publication No. HEI 5-64143, setting of the compression rate is automatically changed for storage so that a number of sheets of compressed image data to be stored will be set as an operator desires, which makes it possible to obtain the best image in the specified range.
Fifthly, as a digital still video camera based on the conventional technology, there is a device for reporting a residual memory space of a recording medium for recording therein photographed images.
For instance, in the “Electronic still camera” disclosed in Japanese Patent Laid-Open Publication No. HEI 2-280483, by estimating a number of sheets of still images which can be recorded in the recording medium from an average memory space of data used for image data recorded in the recording medium as well as from the recorded number of sheets, an appropriate alert can be issued when a residual data memory space in the recording medium becomes a low level.
Also in the “Electronic still camera” disclosed in Japanese Patent Laid-Open Publication No. HEI 6-350950, an empty memory space in the recording medium or a number of pieces which can further be photographed are displayed while alert is issued in at least two or more ways according to the empty memory space in the recording medium.
On the other hand, the digital still video cameras have come to incorporate more and more multiple and versatile functions, so that there are provided various types of recording mode such as, in addition to a still picture mode for recording a photographed image as a still picture, a successively photographing mode for successively recording still pictures, a voice mode for recording voices, a still picture+voice mode for simultaneously recording a still picture and voices, a moving picture mode for recording moving pictures like a video camera, and a character mode for clearly recording characters or the like, or some other modes.
Sixthly, in the digital still video camera based on the conventional technology, as a technology for recording much more data in a recording medium with a limited memory space, there are those as described below. Disclosed in Japanese Patent Laid-Open Publication No. HEI 2-44879 is an invention in which a recording medium can efficiently be used by switching a low-resolution mode switch and changing a number of data bits of a video signal to be written into a memory card.
Also disclosed in Japanese Patent Laid-Open Publication No. HEI 4-332281 is an invention in which a mode is effected in which a screen is compressed with a uniform compression rate in any of the three cases where a distance to an object is not less than a specified value, where a focus length is not more than a specified value, and where a specified relation is satisfied between the focus length and the distance to an object, and in other cases, a recording memory space required for a screen can be reduced by changing a compression rate according to the information obtained by measuring a distance to an object according for each scene to be photographed and concretely, for instance, by reducing the compression rate in an inside area of the outline.
However, with the first image data output system for a digital still video camera based on the conventional technology, any of the systems has configuration in which image data is transferred to a printer through a computer, so that a system for outputting the image data becomes disadvantageously expensive.
It should be noted that a computer is indispensable in a case where various types of editorial word or processing is executed to an image when the image is to be outputted to recording paper, but many users will simply desire print-output of an image, and especially in that case, the expensive system is a big problem for the users.
With the second digital still video camera based on the conventional technology, inputted voice data is only recorded with the technology for voice compression, so that the voice data has not been utilized as an information source for other processing.
As the third case described above, in a case where the function for the radio communication based on the IrDA standard is simply incorporated in the digital still video camera base on the conventional technology, there are such problems that data transfer can not always successfully be executed because the camera is affected by vibration of the equipment generated during the data transfer since the digital still video camera is generally a small-sized one and data to be transferred includes image data having a large quantity of information, and that data transfer can not successfully be executed because it is difficult to maintain a positional relation between the digital still video camera and an external device to which the data is to transferred in the best situation.
As a digital still video camera is generally small-sized and it is difficult to operate the digital still video camera in a state in which a suitable positional relation therebetween is maintained, there are such problems that the operability and convenience during data transfer is low.
With the fourth case described above, and based on the conventional technology described above, an image for one screen is compressed according to a uniform compression ratio, so that a method of thinning information for a complicated section block by block is employed due to restrictions in algorithm for the compression processing in a case where peripheral images have complicated patterns even if the main object is located at the center of the screen in the photographed screen of image, and for this reason a quantity of data for the main object is reduced. In other words, in an image for one screen, a main portion desired by a user can not always be recorded clearly.
In a case where a quantity of information for the main object is increased by simply reducing the compression rate (or without executing compression), a quantity of the information for the entire image for one screen increases disadvantageously.
These problems described above also exist in each of the invention disclosed in Japanese Patent Laid-Open Publication No. HEI 4-332281 and Japanese Patent Laid-Open Publication No. HEI 5-64143.
With the fifth digital still video camera based on the conventional technology, although an appropriate alert can be issued when a remaining memory space for data to be recorded in the recording medium (a residual memory space for recording) becomes a low level, the alert are given by means of display or indication, so that, in a case where a user does not notice the display of alert, sometimes photographed images may not be recorded therein.
In the sixth digital still video camera based on the conventional technology, as a method of making it possible to photograph a more number of sheets of images than that in a normal device, a method of changing a number of data bits or a compression rate is employed, and for this reason quality of an image to be fetched thereinto may entirely or partially be degraded.
It is a first object of the present invention to make it possible to output image data prepared by a digital still video camera based on simple and low-cost configuration to recording paper by directly transferring image data to an image forming apparatus such as a printer or the like without requiring a computer therebetween.
It is a second object of the present invention to improve operability, workability, and convenience in use of a digital still video camera by making use of received voice data as an information source for other types of processing.
It is an object of the present invention that data in a digital still video camera incorporating therein a function of radio communication making use of infrared rays can easily and securely be transferred to an external device. The present invention was also made for solving the problems described above, and it is a third object of the present invention to improve operability and convenience in use thereof when data is transferred from a digital still video camera to external device.
It is a fourth object of the present invention to make it possible to record an image in a desired area (the main portion) with a large quantity of information therefor with a layout intended by a user.
It is a fifth object of the present invention to make it possible to alert a user and accurately report a remaining recording space in a recording medium in which data can be recorded to the user.
It is a sixth object of the present invention to make it possible to freely change a form of a photographed image to be stored in a storage medium by selecting a mask identifying a photographed image area according to an image to be recorded for maximizing a number of sheets of images which can be stored in a storage medium without lowering a quality of the recorded image as well as for effectively utilizing the storage medium.
The digital still video camera according to the present invention having a function for transaction of image data as well as control data with external devices comprises a picture information input means for inputting picture information for an image forming apparatus, one of the external devices; a picture information memory means for storing therein picture information inputted from the picture information input means; and a converting/sending means for converting image data to be sent to the image forming apparatus to image data adapted to the image forming apparatus according to the picture information stored in the picture information memory means and sending the image data using a synchronizing signal adapted to the image forming apparatus, and in the digital still video camera picture information for the image forming apparatus is inputted thereinto by the picture information input means and is stored in the picture information memory means, and the converting/sending means converts image data to be sent to the image forming apparatus to image data adapted to the image forming apparatus according to the picture information and sends the image data using a synchronizing signal adapted to the image forming apparatus.
The digital still video camera according to the present invention having an image data generating means for photographing an image and generating image data for the image and a voice data generating means for inputting voices and generating voice data for the voices to record the generated image data as well as voice data in a recording medium comprises a character code generating means for recognizing voice data generated by the voice data generating means and generating character code corresponding to the voice data; and a recording control means for controlling the image data generating means, the voice data generating means, and the character code generating means, and recording the character code with relation to the image data in the recording medium.

Namely the frame for data relay according to the present invention can simply and accurately transfer data from a digital still video camera to an external device by executing radio communications with the digital still video camera through the radio communication means in a state in which the digital still video camera is stably retained by the retaining means in the frame for data relay and further by transferring the data from the radio communicating means to external device.

Other objects and features of this invention will become understood from the following description with reference to the accompanying drawings.

It should be noted that a liquid crystal monitor 102 which can display photographed images and various types of information and a member card 103 for recording therein photographed images are connected to the basic body 101 of a camera.
The basic body 101 of the camera comprises a lens unit 104 comprising a lens, an automatic focus (AF), an iris, a filter, a mechanical component or the like; a CCD (charge coupled device) 105 for converting an image inputted through the lens unit 104 to an electric signal (analog image data); an A/D converter 105 for converting analog image data inputted from the CCD 105 to digital image data; an IPP (image pre-processor) 107 for dividing the digital image data inputted from the A/D converter 106 to data for chrominence and those for luminance and subjecting the divided data to data processing for various processing, correction and compression/extension of images; a DCT (Discrete Cosine Transform) 108 for executing D/A conversion which is a step of image compression/extension based on the JPEG standard; a coder (Huffman Encoder/Decoder) 109 for executing encoding and decoding each as a process of the image compression/expression based on the JPEG standard; an MCC 110 (Memory Card Controller) for temporally storing therein compressed images and voice data fetched from a microphone 111 and digitalized therein, subjecting the image data and voice data to synchronization, and recording the data in or reading the data from the memory card 103; an ADPCM (Adaptive Differential Pulse Code Modulation) 112 for converting voice inputted through the microphone 111 to digital data and also subjecting the voice data to processing for compression or extension; a CPU 113 for controlling each of the sections described above; an MEM 114 which is a work memory for a system consisting of a ROM and a RAM; a remote control function section 115 having a remotely controlled receiving function; an operation display section 116 for key entry for various types of buttons and switches as well as for display control of a liquid crystal monitor (a liquid crystal panel 119 described later); a battery 117 for supplying an electric power to each of the sections described above; an optical low-pas filter 118; and a communication I/F section 122 for executing communications with an I/F device 201.
The liquid crystal monitor 102 has at least a liquid crystal panel (LCD) 119 and a speaker 120. It should be noted that the reference numeral 121 indicates a battery for the liquid crystal monitor 102.
An I/F device 201 receives image data or the like from the communication I/F section 122 in the basic body 101 of the camera and transfers the image data to a printer 301. For this reason, configuration of the I/F device 201 is based on configuration of the communication I/F section 122 in the basic body 101 of the camera and that of the printer 301, and is not limited to any specific configuration.
The printer 301 comprises an I/F circuit 302 for executing communications with the I/F device 201; an engine section 303 comprising a printer engine or the like; an operation display section 304 for displaying or receiving various types of information; and a control section 305 for controlling each of the sections.
It should be noted that, in Embodiment 1, the picture information input means according to the present invention comprises the liquid crystal monitor 102 and the operation display section 116, the MEM 114 corresponds to the picture information memory means according to the present invention, and the converting/sending means according to the present invention comprises the CPU 113, IPP 107, DCT 108, coder 109, and MCC 110.
Also it should be noted that, although description of the embodiment 1 assumes the configuration in which the basic body 101 of the camera and the I/F device 201, and the I/F device 201 and the printer 301 are connected to each other with a cable respectively as shown in
With the configuration as described above, next description is made for operations for 1) input of picture information and 2) printing with an image data output system for a digital still video camera in this order.
1) Input of picture information
Input of picture information is executed by making the CPU 133 execute a picture information maintenance processing program stored in the MEM 114 and inputting picture information through the liquid crystal monitor 102 and the operation display section 116.
At first, the maintenance mode select screen is displayed on the liquid crystal panel 119 of the liquid crystal monitor 102 to ask a user to select a desired maintenance mode from “1. Input”, “2. Recording”, “3. Deletion”, and “4. End”, and when the user selects a desired maintenance mode, system control shifts to the next step (S301) according to the selected maintenance mode. Herein “input” means processing for inputting picture information anew, “recording” means processing for storing the inputted picture information in the MEM 114, “deletion” means processing for deleting picture information stored in the MEM 114, and “end” means termination of the picture information maintenance processing mode.
When “4. End” is selected in step S301, the processing is terminated as it is.
If any of “1. Input”, “2. Recording”, and “3. Deletion” is selected in step S301, system control advances to step S302 where the corresponding processing is executed, and then system control returns to step S301.
For instance, if “1. Input” is selected in the step, a menu screen for inputting picture information is displayed on the liquid crystal panel 119, and a user is prompted to input picture information. As the picture information to be inputted, there is information about a form size, an orientation of the form, a resolution, a magnification, an offset value (a position for starting printing on recording paper) or the like. Concretely, as shown in FIG. 4A and
It should be noted that, in this embodiment, an offset value and a magnification are automatically selected by the CPU 113 for the reasons as described below. Namely a main object of the present invention is to directly transfer image data to an image forming apparatus such as a printer without asking assistance by a computer, in other words, to transfer image data from the basic body 101 of the camera to the printer 301 as simply as possible, so that a plurality of offset values OX, OY and magnification n are previously prepared in the MEM 114 to simplify computing in processing for deciding layout described later.
Then in a case where “2. Recording” is selected in step S301, the picture information inputted when “1. Input” was selected is stored in the MEM 114. Also in a case where “3. Deletion” is selected, the picture information stored in the MEM 114 is deleted.
2) Printing with an image data output system for a digital still video camera
When printing is executed, if the printing mode is selected in the operation display section 116, the CPU 113 executes operations as shown in the flow chart in FIG. 6.
At first, when a user selects a desired output image using the liquid crystal panel 119 and the operation display section 116 (S601) and then inputs a request for printing (S602), the CPU 113 executes communications with a control section 305 in the printer 301 via the communication I/F section 122, I/F device 201, and I/F circuit 302, and determines whether the printer 301 is ready or not (S603).
If the printer 301 is not ready in this step, the printer 301 is automatically enabled in its side (S604). If the printer 310 is ready, determination is made as to whether picture information is stored in the MEM 114 or not (S605), and if any picture information is not stored therein, the picture information maintenance processing is executed (S606). In this case, the user inputs picture information according to the flow chart shown in FIG. 3 and records the picture information in the MEM 114.
In step S605, if picture information is stored in the MEM 114, the picture development determination processing shown in
Then, determination is made as to whether a stop command has been insured in the image development determination processing or not (S608), and if it is determined that a stop command has been issued, the processing is terminated as it is. If it is determined that a stop command has not been issued, the layout deciding processing in
When the printer 301 receives image data from the digital still video camera, the printer 301 draws the image on recording paper (S612).
The digital still video camera repeats operations in step S611 until transmission of all image data is finished, and when transmission is finished, system control advances to step S614 (S613). In step S614, when a signal indicating end of transmission is received, the printer 301 forcefully discharge recording paper, and terminates the processing. When the transmission is terminated, also processing in the side of the digital still video camera is terminated.
Herein description is made for the image development determination processing with reference to FIG. 7. The CPU 113 estimates the time required for image development from the picture information stored in the MEM 114 (S701), and determines whether the digital still video camera can follow the printer 301 or not (S702). Herein if it is determined that the digital still video camera can follow the printer 301, it is possible to transfer the image, developing it, to the printer 301, so that the processing is terminated as it is. On the other hand, if it is determined that the digital still video camera can not follow the printer 301, the CPU 113 estimates a memory space required for storing the remaining portion of the image (S703), also estimates a residual memory space (empty memory space) in the memory card 103 (S704), and determines whether there is an empty memory space enough to develop the image in the memory card or not from the memory space required for storing the remaining portion of the image as well as from the residual memory of the memory card 103 (S705).
If it is determined that there is a sufficient memory space in step S705, the CPU 113 develops the image, converts the image to data capable of being flown to the printer 301 (or capable of being transferred), and writes the data in the memory card 103 (S706). When development is finished (S707), the processing is terminated as it is.
On the other hand, it is determined that there is not a sufficient memory space in step S705, the CPU 113 displays an instruction of replacement of the memory card 103, displays an instruction for deleting the image in the memory card 103, and also displays choices for stopping and continuing on the liquid crystal panel 119, to prompt the user to select any of the choices (S708). Herein if a user selects a choice for stopping or continuing through the operation display section 116, determination as to whether the processing is to be stopped or not is executed in step S709. For instance, if the user exchanges the memory card 103 with a new one or deletes the image in the memory card 103 and then selects a choice for continuing through the operation display section 116, the CPU 113 executes operations in step S703 to S705, and again executes determination as to whether the image can be developed in the memory card 103 or not. Also if the user selects a choice for stopping, the CPU 113 issues a stop command (S710), and terminates the processing.
Then description is made for the processing for deciding layout with reference to FIG. 8. At first the CPU 113 loads picture information stored in the MEM 114 (S801), decides a printing range (width TW×height TH) on recording paper according to a size and an orientation of the recording paper, sets a fixed image area size (width W×height H) for the digital still video camera, selects particular offset values OX, OY as candidates (a-th candidate) from a plurality of offset values OX, OY, and then selects a particular magnification n as b-th candidate from a plurality of magnification n (S802).
Then the CPU 113 determines whether the image area (width nW×height nH) outputted from the printer 301 decided according to the selected magnification n can be accommodated within the printing range (width TW×height TH) on the recording paper when the selected offset values OX, OY (S803). Herein if the condition of OX+nW<TM and the condition of OY+nH<TH are satisfied simultaneously, the image area can be accommodated within the printing range on the recording paper, so that the CPU 113 terminates an operation for layout using the selected magnification n as well as selected offset values OX, OY (S804), and terminates the processing.
On the other hand, if the image area can not be accommodated within the printing range on the recording paper, the CPU 113 determines whether there is any alternative candidate or not (S805), and if it is determined that there is any candidate, system control returns to step S802, and if it is determined that there is not any alternative candidate, system control goes to step S804, and the CPU 113 terminates the processing.
As described above, with Embodiment 1, by previously inputting picture information stored in the printer 301 into MEM 114, the digital still video camera converts the image data to be sent to the printer 301 to image data adapted to the printer 301 according to the printer information, and sends the image data using a synchronizing signal adapted to the printer 301, so that the digital still video camera can directly transfer the image data to the printer 301 without interference by a computer. For this reason, a computer is not required, and image data in a digital still video camera having simple and low-cost configuration can be outputted to recording paper.
A digital still video camera according to Embodiment 2 of the present invention previously stores therein a plurality types of picture information each corresponding to a type of a printer (herein a connectable printer) in the MEM 114, selects desired picture information using the liquid crystal panel 119 and the operation display section 116, and the CPU 113 converts the image data to be sent to the printer 301 to image data adapted to the printer 301 according to the picture information, and sends the image data to the printer 301 using a synchronizing signal adapted to the printer 301. It should be noted that configuration in Embodiment 2 is the same as that in Embodiment 1 and description is made herein for only different portions.
In Embodiment 2, the present invention comprises a liquid crystal monitor 102 (liquid crystal panel 119) and the operation display section 116, the MEM 114 corresponds to a memory means according to the present invention, and a converting/sending means according to the present invention comprises the CPU 113, IPP 107, DCT 108, coder 109, and MCC 110.
At first a user selects an image the user hopes to output and then inputs a printing request (S601, S602), when the CPU 113 determines whether the printer 301 is ready or not, and enables the printer 301 (S603, S604). If it is determined that the printer 301 is ready for printing, the CPU 113 determines whether picture data is stored in the MEM 114 or not (S605), and if it is determined that any picture information is not stored in the MEM 114, the CPU 113 executes the picture information maintenance processing (S606).
If it is determined in step S605 that picture information is stored in the MEM 114, names of the stored picture information is displayed on the liquid crystal panel 119 (S1001), and a user is prompted to select any picture information (S1002). Herein when the user selects any picture information, the CPU 113 determines the image development determination processing (S607), and executes the subsequent steps S608 to S614 like in Embodiment 1.
As described above, with Embodiment 2, picture information for the printer 301 is previously stored in the MEM 114 and the picture information for the printer 301 to be used is selected when actually a printing operation is executed, when the digital still video camera converts image data to be sent to the printer 301 to image data adapted to the printer 301 according to the picture information according to the picture information, and at the same time the image data using a synchronizing signal adapted to the printer 301 is sent, so that it is possible to directly transfer image data to the printer 301 without requiring interference by a computer. For this reason, a computer is not required and image data in a digital still video camera can be outputted to recording paper with low cost configuration.
Also as specific information is included in the picture information, general users sometimes get embarrassed, but as it is possible to consistently manage picture information for each printer (image forming apparatus) using a computer and to fetch a plurality types of picture information into the MEM 114 through the memory card 103, so that printing can easily be executed easily even in a case where a user not having any special knowledge uses a digital still video camera. Also a work load for inputting picture information can largely be reduced.
A digital still video camera according to Embodiment 3 of the present invention reads picture information from the printer 301 when outputting image data through the printer 301, converts the image data to be sent to the printer 301 to image data adapted to the printer 301 according to the picture information read as described above, and sends the image data using a synchronizing signal adapted to the printer 301.
It should be noted that, in Embodiment 3, the picture information storing section 306 corresponds to a first memory means according to the present invention, the control section 305 corresponds to a sending means according to the present invention for sending picture information stored in the picture information storing section 306 to the side of the digital still video camera in response to a request from the digital still video camera, the CPU 113 corresponds to a picture information reading means according to the present invention for requesting the control section 305 to send picture information and reading the picture information in a case where the CPU 113 outputs image data through the printer 301, and the MEM 114 corresponds to a second memory means according to the present invention for storing therein the picture information read from the CPU 113. A converting/sending means according to the present invention comprises the CPU 113, IPP 107, DCT 108, coder 109, and MCC 110.
At first a user selects a desired image to be outputted and then inputs a request for printing (S601, S602), when the CPU 113 determines whether the printer 301 is ready for printing or not, and enables the printer (S603, S604). If the printer 301 is ready for printing, the CPU 113 sends an inquiry concerning the state of the printer 301 to the control section 305 of the printer 301, and determines whether the maintenance function for picture information is available or not (S1201).
In step S1201, if it is determined that the maintenance function for picture information is not available in the side of the printer 301, the picture information maintenance processing in step S606 is executed and the digital still video camera receives the picture information, and then the CPU 113 executes operations in step S607 to step S614.
On the other hand, in step S1201, if it is determined that the picture information maintenance function is available in the side of the printer 301, system control advances to step S1202. In step S1202, the control section 305 of the printer 301 makes the current set-up state (picture information) stored in the picture information storing section 306. On the other hand, the CPU 113 inputs the picture information stored in the picture information storing section 306 from the printer 301 to the MEM 114 to store the picture information therein (S1203). Then the CPU 113 executes subsequent operations in steps S608 to S614 like in Embodiment 1.
As described above, with Embodiment 3 above, by previously storing picture information in the picture information storing section 305 in the side of the printer 301, it becomes possible to further easily and quickly set the picture information. Also by deciding specifications for a format of picture information, picture information can be used also from other equipment (such as, for instance, a computer).
The basic body 101 of the camera comprises a lens unit 104 comprising a lens, an automatic focus (AF), an iris, a filter, a mechanical component or the like; a CCD (charge coupled device) 105 for converting an image inputted through the lens unit 104 to an electric signal (analog image data); an A/D converter 106 for converting analog image data inputted from the CCD 105 to digital image data; an IPP (image pre-processor) 107 for dividing the digital image data inputted from the A/D converter 106 to data for color difference and those for luminance and subjecting the divided data to data processing for various processing, correction and compression/extension of images; a DCT (Discrete Cosine Transform) 108 for executing D/A conversion which is a step of image compression/extension based on the JPEG standard; a coder (Huffman Encoder/Decoder) 109 for executing encoding and decoding each as a process of the image compression/extension based on the JPEG standard; an MCC (Memory Card Controller) 110 for temporally storing therein compressed image data and voice data fetched from a microphone 111 and digitalized therein, subjecting the image data and voice data to synchronization, and recording the data in or reading the data from the memory card 103; a microphone 111 which is voice data generating means for inputting voices and generating voice data; an ADPCM (Adaptive Differential Pulse Code Modulation) 112 for converting voice inputted through the microphone 111 to digital data and also subjecting the voice data to processing for compression or extension; a CPU 113 for controlling each of the sections described above; an MEM 114 which is a work memory for a system consisting of a ROM and a RAM; a remote control function section 115 having a remotely controlled receiving function; an operation display section 116 for key entry for various types of buttons and switches described later as well as for display control of a display panel; a battery 117 for supplying an electric power to each of the sections described above; an optical low-pas filter 118 provided between the lens unit 104 and the CCD 105; and a CG (character information generating device) 122 for generating character code.
The liquid crystal monitor 102 comprises at least the liquid crystal panel (LCD) 119 and the speaker 120. It should be noted that the reference numeral 121 indicates a battery for the liquid crystal monitor 102.
In
FIG. 14A and
FIG. 14A and
It should be noted that, in this figure, the reference numeral 1410 indicates a card insertion port for inserting the memory card 103, and the reference numeral 1411 indicates a battery cover for a battery section in which the battery 117 is accommodated. Also as shown in this figure, the microphone 111 is provided therein.
Also the reference numeral 1412 indicates a display panel, and as shown in this figure, the display panel is provided on a top surface of the basic body of the camera, and displays a state of the battery and a state of a camera such as a number of sheets which can be prepared, a set mode, or the like with marks or figures.
It should be noted that, although the figure shows the state in which all types of information are displayed simultaneously, but practically only required information is displayed. Also in Embodiment 4, as described later, it is assumed that display of the still picture+voice mode is provided by using the still picture mode display section 1506 and the voice mode display section 1507 and also display of the moving picture +voice mode is provided by using the moving picture mode display section 1509 and the voice mode display section 1507.
With the configuration described above, description is made for the operations.
At first if the selected mode is a voice mode for recording data including voices, zero is set in a mode flag rec, and if it is a still picture+voice mode or a moving picture+voice mode, 1 is set in the mode flag rec (S1701).
Then determination is made as to whether the recording mode rec is 0 or not (S1702), and if it is determined that rec=0, a user executes a voice input through the microphone 111 as long as a user desires (S1703), then system control goes to step S1704. On the other hand, if it is determined that rec is not 0, a user executes a voice input through the microphone 111 within a preset period of time x (S1704), then system control goes to step S1705.
In step S1705, the inputted voice data is converted to digital data with the ADPCM 112, and is compressed and temporarily stored in the memory card 103. Then, the CPU determines whether voice recording is complete or not (S1706) and repeats step S1703 and step S1705 until the voice recording is finished. It should be noted that, in a case wherein the recording mode rec is not 0 (namely, a case of rec=1), the voice recording is finished within the x period of time through step S1704, so that it is determined that the voice recording is always finished in step S1706, then system control goes to step S1707.
In step S1707, the CPU 113 identifies corresponding character information by recognizing voices using the voice data temporarily stored in the memory card 103. Then the CPU 113 generates character code for the corresponding character information by controlling the CG 122 (S1708), and determination is made as to whether generation of character code is finished or not, in other words, whether all of the voice data has been converted to character code or not (S1709), then the CPU 113 repeats step S1707 and step S1708 until generation of all the character code is finished.
In step S1709, in a case where it is determined that generation of the character code is finished, the CPU 113 deletes the voice data temporarily stored in the memory card 103 (S1710), and saves (records) the generated character code in the memory card 103 (S1711).
Then, determination is again made as to whether the recording mode rec is 0 or not (S1712), and if it is determined that rec=0, it is determined that the mode is a voice mode for recording therein only voices, so that the CPU 113 terminates the processing as it is. On the other hand, if it is determined that rec is not 0, the mode is a still picture+voice mode or a moving picture+voice mode each for recording images other than voices, so that the CPU 113 photographs an image (S1713), saves (records) the inputted image data with reference to the character code previously recorded in the memory card 103 as an identical file (S1714), and terminates the processing.
With the processing as described above, the character code generated according to the inputted voice data and the image data related to the character code are recorded in the memory card 103 as an identical file. For this reason, the voice data is recorded therein as character code which can easily be processed by the computer, so that the character code (namely, the inputted voice data) can easily be made use of as an information source for other processing, which makes it possible to improve the operability, workability, convenience in use of the digital still video camera.
Next description is made for regeneration processing in the mode for recording data including voices with reference to FIG. 18.
At first, when a power is turned ON by operating the main switch 1401 in the regenerating mode, the CPU 113 displays a file name or a number of the information (images and voices) recorded in the memory card 103 on the liquid crystal panel 119, and prompts a user to select information for regeneration. Herein, when the user selects desired information to be regenerated from the file name or the number each displayed on the liquid crystal panel 119 through the operation display section 116 (S1801), the CPU 113 determines whether character code is included in the selected information to be regenerated or not (S1802).
In a case where it is determined that there is not character code in the selected information to be regenerated, system control goes to step S1803, and the CPU 113 executes the ordinary regeneration processing and terminates the processing although detailed description thereof is omitted herein.
Also, in a case where it is determined that there is character code in the selected information to be regenerated, determination is made as to whether the recording mode rec=0 or not (S1804), and if it is determined that rec=0, the CPU 113 reads out the character code for the corresponding information to be regenerated from the memory card 103 (S1805), regenerates the character code to voice data, regenerates the voice data to voices through the speaker 120 for outputting, and displays the character code on the liquid crystal panel 119 (S1806), and then terminates the processing.
If it is determined that rec is not 0, as the regeneration information indicates that it has character code and image data, the CPU 113 reads the character code and the image data each for the corresponding regeneration information from the memory card 103 (S1807), regenerates the character code to voice data, then regenerates the voice data to voices through the speaker 120 for outputting, regenerates the image data to be displayed on the liquid crystal panel 119, and further displays the character code on the liquid crystal panel 119 (S1808), and terminates the processing.
As described above, in Embodiment 4, as voice data is previously converted to character code to be recorded in the memory card 103, the character code can be converted to and regenerated as voices (voice data), and can also be recognized by displaying the character code on the liquid crystal panel 119, which makes it possible to improve the convenience for users in use thereof.
Furthermore, by recording therein character code converted from voices, for instance, it is possible to fetch the character code on a personal computer which is an external device and to edit it to a document (for instance, by pasting) as it is (or by converting it to kanji). Reversely, by recording a document edited on the personal computer in the memory card 103 and regenerating it with the digital still video camera, image data and character code (kanji) can simultaneously be regenerated. Also, even in a case where voices are hardly heard, or even in a case where voices can not be outputted, it is possible to know the information with the characters displayed on the screen. In other words, by making use of the inputted voice data as an information source for other processing, the operability, workability, and convenience in use of the digital still video camera can be improved.
Also, after voice data is inputted to generate character code, an image is photographed and image data for the image is generated, then the character code and image data are recorded in a recording medium as an identical file, so that it is easy to relate character code to image data.
The digital still video camera according to Embodiment 5 generates voiceprint information from the inputted voice data, and determines whether the digital still video camera is enabled or is inhibited to use by making use of the voiceprint information, whereby security of the information can be improved. It should be noted that the configuration in Embodiment 5 is basically the same as that in Embodiment 4 shown in
In Embodiment 5, the CPU 113 and the CG 122 in
At first, when a user makes voice (sound) within the preset y seconds, the CPU 113 receives voice data through the microphone 111 and analyzes the voiceprint data to generate voiceprint information α (S2001). Then, when the user makes voice again, the CPU 113 receives the voice data through the microphone 111, analyzes the voiceprint of the data to generate voiceprint information β (S2002), and makes determination as to whether the voiceprint information α and the voiceprint information β are identical to each other or not (S2003). Herein, if it is determined that the voiceprint information α is not identical to the voiceprint information β, system control returns to step S2001 and the CPU 113 executes the same processing again. On the other hand, if it is determined that the voiceprint information α is identical to the voiceprint information β, the user is prompted to select processing whether the voiceprint information is to be registered or not (S2004), and if “to be registered” is selected, the CPU 113 registers the generated voiceprint information (α or β) to the MEM 114 in the basic body 101 of the camera as registered voiceprint information (S2005). On the contrary, if “not to be registered” is selected, the CPU 113 terminates the processing immediately.
At first, when the user turns ON the main switch 1401 in the basic body 101 of the camera (S2101), the registered voiceprint information previously registered in the MEM 114 in the voiceprint information registering processing is inputted (S2102). Then, when the user makes voice (sound) within the preset z seconds, the CPU 113 receives voice data through the microphone 111, and analyzes the voiceprint of the data to generate inputted voiceprint information (S2103).
Then the CPU 113 compares the registered voiceprint information to the inputted voiceprint information, and makes determination as to whether both of the voiceprint information are identical to each other or not (S2104). Herein if it is determined that the registered voiceprint information and the inputted voiceprint information are identical to each other, the fact indicates that a person who uses the basic body 101 of a camera is identical to the person having the registered voiceprint information for which the camera is permitted to be used, so that the basic body 101 of the camera is enabled (S2105), and the processing is terminated. On the other hand, if it is determined that the registered voiceprint information and the inputted voiceprint information are not identical to each other, the fact indicates that a person who uses the basic body 101 of a camera is not identical to the person having the registered voiceprint for which the camera is permitted to be used, so that the basic body 101 of the camera is disabled and a message indicating the disabled state is displayed on the screen (S2106), and the processing is terminated.
As described above, with Embodiment 5, by previously generating voiceprint information from voice data to be registered to the camera, voiceprint information for an individual can be used like a password used for a personal computer or the like, which makes it possible to enhance security of digital still video camera. Also, in addition to the security, various types of conditions concerning photographing set in the basic body 101 of the camera are not changed without permission, and for this reason convenience in use thereof is improved.
Namely, inputted voice data is made use of as an information source for other processing, which makes it possible to improve the operability, workability, and convenience in use of the digital still video camera.
The digital still video camera according to Embodiment 6 generates voice information from inputted voice data to be registered in a recording medium, and security of the information in the recording medium is improved by making determination with the voiceprint information as to whether each of recording mediums is permitted to be used or is inhibited to be used. It should be noted that the configuration in Embodiment 6 is basically the same as that in Embodiment 4 shown in
In Embodiment 6, the CPU 113 and the CG 122 in
At first, when a user makes voice (sound) within the preset y seconds, the CPU 113 receives voice data through the microphone 111 and analyzes the voiceprint of the data to generate voiceprint information α (S2201). Then, when the user makes voice again, the CPU 113 receives voice data through the microphone 111, analyzes the voiceprint of the data to generate voiceprint information β (S2202), and makes determination as to whether the voiceprint information α and the voiceprint information β are identical to each other or not (S2203). Herein, if it is determined that the voiceprint information α is not identical to the voiceprint information β, system control returns to step S2201 and the CPU 113 executes the same processing again. On the other hand, if it is determined that the voiceprint information α is identical to the voiceprint information β, the user is prompted to select processing whether the voiceprint information is registered or not (S2204), and if “to be registered” is selected, the CPU 113 registers the generated voiceprint information (α or β) to the memory card 103 as registered voiceprint information (S2205). On the contrary, if “not to be registered” is selected, the CPU 113 terminates the processing as it is.
At first, when the user turns ON the main switch 1401 in the basic body 101 of the camera or exchanges the memory card 103 with other one (S2301), the registered voiceprint information previously registered in the memory card 103 with the voiceprint information registering processing is inputted (S2302). Then, when the user makes voice (sound) within the preset z seconds, the CPU 113 receives voice data through the microphone 111, and analyzes the voiceprint of the data to generate inputted voiceprint information (S2303).
Then the CPU 113 compares the registered voiceprint information to the inputted voiceprint information, and makes determination as to whether both of the voiceprint information are identical to each other or not (S2304). Herein if it is determined that the registered voiceprint information and the inputted voiceprint information are identical to each other, the fact indicates that a person who uses the inserted memory card 103 is identical to the person having the registered voiceprint information for which the memory card 103 is permitted to be used, so that the memory card 103 is permitted to be used (S2305), and the processing is terminated. On the other hand, if it is determined that the registered voiceprint information and the inputted voiceprint information are not identical to each other, the fact indicates that a person who uses the inserted memory card 103 is not identical to the person having the registered voiceprint information for which the memory card 103 is permitted to be used, so that the memory card 103 is disabled and alert indicating that the memory card 103 has to be exchanged with other one is issued (S2306), and the processing is terminated.
As described above, with Embodiment 6, by previously generating voiceprint information from voice data to be registered into the memory card 103, voiceprint information for an individual can be used like a password used for a personal computer or the like, which makes it possible to enhance security of each of memory cards. Especially, in Embodiment 6, different from Embodiment 5, the basic body 101 of a camera is permitted to be used by a large number of unspecified users, and only the memory card 103 can confidentially be handled. Furthermore, by executing the voiceprint information checking processing shown in
Namely, inputted voice data is made use of as an information source for other processing, which makes it possible to improve the operability, workability, and convenience in use of the digital still video camera.
As for a digital still video camera according to Embodiment 7 having the same configuration and operations as those in Embodiment 4, operations are executed according to an operational sequence shown in the flow chart for recording processing in the recording mode including therein voices shown in
At first if the selected mode is a voice mode in the mode for recording data including voices, zero is set in a mode flag rec, and if it is a still picture+voice mode or a moving picture+voice mode, 1 is set in the mode flag rec (S1701). Then determination is made as to whether the recording mode rec is 0 or not in step S1702, and if it is determined that rec=0, a user executes a voice input through the microphone 111 as long as a user desires (S1703) because zero indicates a voice mode for recording only voices, then system control goes to step S1705.
On the other hand, if it is determined that rec is not 0, which indicates that the mode is a still picture+voice mode or a moving picture+voice mode each for recording images other than voices, so that the CPU photographs an image (S2401), saves (records) the inputted image data in the memory card 103 (S2402), then a user executes a voice input through the microphone 111 within x period of time preset in step S1704, then system control goes to step S1705.
Then, the CPU 113 executes the processing from step S1705 to step S1710, and then makes again determination as to whether the recording mode rec is 0 or not (S2403), and if it is determined that rec=0, the mode is a voice mode for recording only voices, so that the CPU 113 saves (records) the generated character code in the memory card 103 (S2404), and terminates the processing. On the other hand, if it is determined that rec is not 0, the mode is a still picture+voice mode or a moving picture+voice mode each for recording images other than voices, so that the CPU 113 relates the generated character code to the image data previously recorded in the memory card 103 and saves (records) the data as an identical file (S2405), and terminates the processing.
As described above, with Embodiment 7, in addition to the same effect as that obtained in Embodiment 4, the CUP 113 photographs an image and generates image data for the image, then inputs voice data to generate character code, and records the image data and the character code in the recording medium as an identical file, so that it is easy to relate character code to image data.
The digital still video camera 2501 comprises a transmitting/receiving section 2501a for data transaction through radio communications making use of infrared rays, an operation display section 2501b for operating the digital still video camera 2501, and a control section 2501c for controlling the digital still video camera 2501.
The DSVC drive 2502 comprises a mounting tray 2502a as a retaining means for stably supporting the digital still video camera 2501, a transmitting/receiving section 2502b as a radio communicating means for data transaction through radio communications with the digital still video camera 2501 mounted (retained) by the mounting tray 2502a, and an I/F (interface) circuit 2502c as a data input/output means for outputting data inputted from the transmitting/receiving section 2502b to the computer 2503 and also outputting data inputted from the computer 2503 to the transmitting/receiving section 2502b. It should be noted that, in the figure, the reference numeral 2502d indicates a window for communications provided on the mounting tray 2502a in which the transmitting/receiving section 2502b and the transmitting/receiving section 2501a of the digital still video camera 2501 are provided at positions opposite to each other.
The computer 2503 comprises an I/F circuit 2503a for inputting data to/outputting data from an I/F circuit 2502c of the DSVC 2502, an operation display section 2503b for operating the computer 2503, a memory 2503c storing therein a DSVC application program (the application means according to the present invention) for controlling operation of the digital still video camera 2501, and a control section 2503d for controlling the computer 2503.
After mounted, when the mounting tray 2502a is pulled into the DSVC drive 2502, the digital still video camera 2502 is accommodated together with the mounting tray 2502a in the DSVC drive 2502, the transmitting/receiving section 2501a and the transmitting/receiving section 2502b are fixed at positions correcting opposing to each other with the communication window 2502d therebetween.
With the configuration described above, next description is made for operations thereof with reference to FIG. 27 and FIG. 28.
As shown in
Then, determination is made as to whether the DSVC application program has been installed in the communicating device or not (S2704), and if it is determined that the DSVC application program has been installed therein, an operation key of the operation display section 2501b in the DSVC drive is locked (S2705), and system control advances to step S2706. On the other hand, if it is determined that the DSVC application program has not been installed, system control goes to step S2706.
In step S2706, the DSVC drive 2507 is enabled. Then, an operating mode is selected, operations are executed in the selected mode (S2707) under operation control with the operation display section 2501b of the DSVC drive 2502 or under control by the DSVC application program installed in the communicating device, and then when the end mode is selected (S2708), the processing is terminated.
It should be noted that modes executable in the digital still video camera 2501 include, for instance, a recording mode for recording image and voice data, an editing mode for deleting image and voice data, a regenerating mode for regenerating image and voice data, a searching mode for searching image and voice data, and end mode for instructing end of the processing.
Also in a case where operations of the digital still video camera 2501 are controlled by the computer 2503, operations as shown in
Then with the DSVC application program, operation control for the digital still video camera 2501 is executed (S2803), and when all the operations are executed, an end command is inputted (S2804), when the processing is terminated.
As described above, with Embodiment 8, radio communications is executed between the transmitting/receiving section 2501a and the transmitting/receiving section 2502b in the state where the digital still video camera 2501 is stably supported on the mounting tray 2502a of the DSVC drive 2502, and also data is transferred from the transmitting/receiving section 2502b via the I/F circuit 2502c to the computer 2503, so that data in the digital still video camera 2501 is simply and accurately transferred to the computer 2503 (external device).
In a case where the DSVC application program has been installed in the computer 2503, entry from the operation key of the digital still video camera 2501 is inhibited and operation control for the digital still video camera 2501 is executed using the DSVC application program from the side of the computer 2503, so that operability and convenience in data transfer from a digital still video camera to a computer (external device) can be improved.
It should be noted that, in Embodiment 8, as shown in
Further, although description of Embodiment 8 assumes a case where an external device to which the DSVC drive 2502 is connected is the computer 2503, the configuration is allowable in which the DSVC drive 2502 is connected to the printer 2901 and data in the digital still video camera 2501 is directly outputted to the printer 2901. Further as shown in
Further a form of the DSVC drive 2502 as a frame for data relay is not limited to that described above, and for instance the construction is allowable in which an upper section of the DSVC drive 2502 is opened so that operation keys of the digital still vide camera 2501 can be operated in the state where the digital still video camera 2501 is mounted on the mounting tray 2502a.
A data transfer system of the digital still video camera according to Embodiment 9 has the same configuration as that in Embodiment 8 shown in
It should be noted that, in
Then in step S3004, determination is made as to which of the DSVC operation and external device operation has been selected in the initiative mode, and if it is determined that the DSVC operation has been selected, the operation display section 2501b of the digital still video camera 2501 is validated (S3005). If it is determined that the DSVC operation has not been selected, the operation display section 2503b of the external device (computer 2503) is validated (S3006).
Then determination is made as to whether the current operating mode is the end mode or not (S3007), and if it is determined that the current operating mode is the end mode, the processing is terminated. If it is determined that the current operating mode is not the end mode, system control returns to step S3003, and mode selection and execution of operations are repeated according to the operation control from the operation display section selected in the initiative mode.
As described above, with Embodiment 9, with which of the digital still video camera 2501 and an external device operation control for the digital still video camera is executed can be selected in the side of the digital still video camera 2501, so that, in a case where an external device is a machine capable of executing advanced operation control, the external device operation is selected so that the external device take a charge for image output like a printer or the like, and in a case where the external device is a machine with low operability, the digital still video camera 2501 can be selected. In other words, it is possible to improve the operability and convenience in data transfer from the digital still video camera 2501 to an external device.
A data transfer system of the digital still vide camera according to Embodiment 10 of the present invention has the same configuration as that in Embodiment 8 shown in
The functions of the operation section of the digital still video camera 2501 are compared to those of the communicating device, and determination is made whether the functions of the operation section of the digital still video camera 2501 are more excellent as compared to those of the communicating device or not (S3101).
Herein if it is determined that functions of the operation section of the digital still video camera 2501 are more excellent, the operation display section 2501b of the digital still video camera 2501 is validated (S3102), and system control advances to step S2706.
If it s determined that functions of the operation section of the communicating device are more excellent, the operation display section of the communicating device (herein the operating display section 2503b of the computer 2503), is validated (S3103), and system control advances to step S2706.
In step S2706, the digital still video camera 2501 is enabled. Then mode selection and operations in the selected mode are executed according to operation control from the validated operation display section (S2707), and if the end mode is selected (S2708), the processing is terminated.
As described above, with Embodiment 10, an operation display section of the digital still video camera 2501 or an external device, either one with more excellent operability, is automatically validated, so that it is possible to improve operability and convenience in data transfer from a digital still video camera to an external device.
In the configuration shown in
It should be noted that, although the figure shows the state where all types of information are simultaneously displayed, actually only necessary information is displayed.
Next description is made for a method of selecting mask information (a method of specifying mask information) as well as for configuration of mask information with reference to
As described in relation to
As shown in the figure, each mask information is built with a combination of a blank section and a shadowed section, and the black section indicates a portion to be processed with a low compression rate or without compression, and the shadowed section indicates a portion to be processed with a high compression rate. In other words, an object to be photographed as a basic body to be recorded is present in the blank section so that recording is executed without losing information so much (or the information has been recorded), while the shadowed section is a portion in which recording is executing (or was executed) with a substantial portion of the information lost.
Furthermore, the mask information corresponding to each of the mask information numbers No.1 to No.3 indicates two types of compression rate indicated by the black section (a section with a low compression rate or without compression) and a shadowed section (with a high compression rate), and the mask information corresponding to the mask information number No.4 indicates a case where three types of compression rate including the two types above and a dot point section (with a intermediate compression rate) are used.
Herein an example of configuration of the mask information corresponding to the mask information number “No.2” shown in
As for the mask information corresponding to the mask information number “No.2”, “0” is set in each of the blocks in the shadowed section where compression (or extension) is executed with a high compression rate, and “1” is set in each of the blocks in the blank section where compression (or extension) is executed with a low compression rate or with no compression is not executed. It should be noted that, in the processing for recording or regeneration described later, by using “0” and “1” set in the blocks respectively, an image can be obtained by regenerating the black section in which a photographed object as a basic body is present with a large volume of information and the peripheral shadowed section with a small quantity of information.
With the configuration described above, next description is made for operations thereof in the order of 1) processing for recording (compression) in the mask compression mode, 2) processing for regeneration (or for extension) of an image, and 3) processing for editing mask information (generation and updating of mask information).
1) Processing for recording (compression) in the mask compression mode
Then when the user presses down the release button 1406, photographing is started and image data is inputted via the lens unit 104, CCD 105 and A/D converter 106 into the IPP 107 (S3702).
The IPP 107 executes the processing for compression changing the compression rate according to each blocks for the specified mask information and a compression rate thereof. It should be noted that change of a compression rate in this embodiment means change of a compression rate according to chrominance of image data. The image data outputted from the IPP 107 is recorded via the DCT 108, coder 109, MCC 110 into the memory card 103 (S3703). It should be noted that the CPU 113 adds, when recording compressed image data via the MCC into the memory card 103, mask identifying information for identifying the mask information used in the image data.
Herein description is made for processing for recording an image according to the mask information in step S3703 with reference to the flow chart shown in FIG. 38. It should be noted that the following description is made for the purposes of simplification for a case where the processing for recording is executed using two types of compression rate (low compression rate; 0, and high compression rate: 1). At first, the image data is divided according to block of the mask information, determination is made as to whether mask information for a block to be processed is “0” or not (S3801), and if it is determined that the mask information for the block is “0”, the block to be processed is compressed with a high compression rate (S3802), the corresponding image data is written in the memory card 103 (S3804), determination is made as to whether the block to be processed is a final one or not (S3805), and if it is determined that the block is not a final one, the block for processing is shifted (S3806), and system control returns to step S3801.
On the other hand, if it is determined in step S3801 that the mask information is not “0”, the block to be processed is compressed with a low compression rate or with no compression (S3803), and the operations in step S3804 and on are executed.
As described above, image data is recorded in the memory card 103 changing a compression rate using the mask information, so that an image in the intended area (a main portion) can be recorded with a high volume of information according to a design intended by the user.
2) Processing for regenerating (extension of) an image
Next description is made for the processing for regenerating image data having been subjected to compression using mask information. In a case where an image recorded in the memory card 103 is regenerated, when a main switch 1401 is set in the regeneration mode, the image (a name or a number of an image file) stored in the memory card 103 is displayed on the liquid crystal panel 119. When a user selects a desired image to be regenerated via the operation display section 116 from the displayed images (S3901), the CPU 113 determines whether mask identifying information has been added to the image or not (S3902), and if it is determined that the mask identifying information has not been added, the CPU 113 reads out the image (compressed image) from the memory card 103, extends the corresponding image through the coder 109, DCT 108, and IPP 107, and displays the regenerated image on the liquid crystal panel 119 (S3903).
On the other hand, if it is determined that the mask identifying information has been added, the CPU 113 identifies the used mask information from the mask identifying formation, reads out the mask information from the MEM 114, and sets the mask information in the IPP 107 (S3904). Then the CPU 113 reads out the image (compressed image) from the memory card 103, transfers the image data via the coder 109, DCT 108 to the IPP 107, executes the processing for extension changing a compression rate (herein, an extension ratio) according to each of the blocks of the mask information set in the IPP 107 and a compression thereof as described above, and displays the regenerated image on the liquid crystal panel 119 (S3905).
As described above, it is possible to regenerate an intended area (a main portion) of an image recorded in the memory card 103 by using mask information and changing a compression rate according to a layout intended by a user and with a high volume of information.
It should be noted that, although the description of this embodiment above assumes a case where the digital still video camera itself is an image regenerating device, configuration of the embodiment is not limited to that described above, and for instance, an image regenerating device dedicated to a computer or a work station may be used.
Also it is possible to provide a selecting means for selecting desired mask information from a plurality of mask information in the side of the image regenerating device so that a user can select mask information to regenerate (or extend) the image.
3) Processing for editing mask information (processing for preparing and updating mask information)
Next description is made for the processing for editing mask information (processing for preparing the updating mask information) with reference to FIG. 40. When the processing for editing mask information is executed, when a user calls out the mask information select screen shown in
At first when a user specifies a mask information number from the mask information select screen and selects desired mask information, the selected mask information is displayed on the liquid crystal panel 119 (S4001). Then, the user adjusts a position and a width for dividing the image changing the compression rate with the liquid crystal panel 119 and the operation display section 116 to further set a new compression rate (S4002). Then the user presses down a specified button to input end of the adjustment (S4003), when the mask information is generated with the h×w blocks described above (S4004).
Then whether mask information is to be registered in the liquid crystal panel 119 or not is displayed (S4005), and if it is specified to register the mask information in the liquid crystal panel 119, the user is prompted to input (specify) a mask information number to be registered, and when the number is inputted (S4006), the mask information is recorded with the corresponding number in the MEM 114 (S4007), and then the processing is terminated.
On the other hand, if it is specified not to register the mask information in step S4005, whether the mask information is to be deleted or not is displayed on the liquid crystal panel 119 (S4008), and if deletion is selected, the user is prompted to input (specify) a mask information number to be deleted, and when the number is inputted (S4009), the mask information corresponding to the number is deleted from the MEM 114 (S4010), and the processing is terminated. If no deletion is selected in step S4008, the processing is terminated immediately.
As described above, as a user can prepare and update arbitrary mask information, for instance in a case where many images each having a specified distance and a layout are to be photographed, it is possible to record the required portion according to the user's intention without substantially reducing a volume of information. Also it is possible to set a compression rate according to the layout and a freedom in setting a compression rate increases.
It should be noted that, although
In Embodiment 12,
With the configuration above, now description is made for operations thereof.
When the main switch 1401 of the basic body 101 of the camera is switched to power ON (recording mode) or power ON (regenerating mode) (S4201), the CPU 113 starts initial setting for the system, and at the same time computes a residual memory space variable for recording in the memory card 103 (S4202).
It should be noted that the residual memory space (capacity A) for recording in the memory card 103 can be computed by subtracting memory space having been used for recording various types of memory space from a rate memory capacity of the memory card 103. Also a method is allowable in which a residual space memory is recorded at a certain area of the memory card 103, and in this case, after power is turned ON, the recorded residual space may be read out from the memory card 103.
Then, initial setting for the system is finished, and so long as any error is not generated, the system is enabled (S4203).
When the system is enabled, a user selects a mode through the operation display section 116 and inputs the selected mode, when the CPU 113 executes operation (1) to (4) in the selected mode (S4204). Although detailed description is not made herein, the recording mode is selected by setting the main switch 1401 in power ON (recording mode), and the deleting mode as well as the residual memory space reporting mode is set as the power is turned ON (regenerating mode) and the mode selection is executed. Also the end mode is selected by setting the main switch 1401 in power OFF and is executed before actually the power is disconnected.
It should be noted that the capacity D=Capacity A−Capacity B+Capacity C.
Then, determination is made as to whether system operation is to be terminated or not (S4205), and if it is determined that the system operation is to be terminated, the processing is terminated. If not, determination is made as to whether the residual memory space reporting mode has been set or not (S4206), and if it is determined that the residual memory space reporting mode has not been set, system control returns to step 4204, and if it is determined that the residual memory space reporting mode has been set, system controls goes to step S4207.
In step S4207, a number of remaining sheets of pictures which can be photographed and a remaining period of time operable in each recording mode (such as the still picture mode or voice mode) is computed from a residual memory space (capacity D) at the current point of time. Then the number of remaining sheets of pictures and remaining period of time (namely the residual memory space D) are communicated in voice through the speaker 120, and then system control returns to step S4204.
It should be noted that there are a number of recording modes in a digital still vide camera including a still picture mode, a still picture+voice mode, a successively photographing mode, a moving picture mode, a voice mode, and character mode. For this reason, a memory space required for recording in the memory card 103 varies according to the recording mode. So it is important to compute a residual memory space available for recording in each recording mode and communicate it in voice through the speaker 120.
Also when an image is recorded, if a plurality levels of compression rates in recording can be selected, a memory space available for recording is computed for each compression rate, and further when a compression rate automatically changes according to an object to be photographed, a residual memory space is computed using a compression rate for the highest image quality. Also in a case of voices, if the compression rate can be changed, a residual memory space is computed for each compression rate.
As described above, by setting the residual memory space reporting mode, each time the recording mode or the deleting mode is executed, a residual memory space available for recording at the point of time is communicated in voice, so that it is possible to alert a user with voice communications and accurately tell the user the residual memory space for recording in the memory card 103. Also it is not necessary to check the display panel 1412 of the basic body 101 of the camera, so that the user can concentrate only to an object to be photographed when photographing an image. Also it is not necessary for a user to remember many display codes even in a case where the display panel 1412 is small, so that the user can always check a residual memory space available for recording, which improves convenience in use of the digital still vide camera.
In the digital still video camera according to Embodiment 13 of the present invention, in a case where the residual memory space reporting mode is set, it is possible to specify any of a plurality of voice output means (speaker 120 and earphone jack 122) for output of voice for reporting the residual memory space to the user.
It should be noted that, as configuration of the digital still video camera is the same as that in Embodiment 12, description is made herein only for different portions.
Then system initialization is finished, and if there has occurred no error, the system is enabled (S4303).
When the system is enabled, a user selects a mode through the operation display section 116 and inputs the selected mode, when the CPU 113 executes operation (1) to (4) in the selected mode (S4304). Although detailed description is not made herein, the recording mode is selected by setting the main switch 1401 in power ON (recording mode), and the deleting mode, the residual memory space reporting mode, and the earphone mode (a mode in which the earphone jack 122 is specified as a voice output means) are set as the power is turned ON (regenerating mode) and the mode selection is executed. Also the end mode is selected by setting the main switch 1401 in power OFF and is executed before actually the power is disconnected.
It should be noted that the capacity D=Capacity A−Capacity B+Capacity C.
Then, determination is made as to whether system operation is to be terminated or not (S4305), and if it is determined that the system operation is to be terminated, the processing is terminated. If not, determination is made as to whether the residual memory space reporting mode has been set or not (S4306), and if it is determined that the residual memory space reporting mode has not been set, system control returns to step 4304, and if it is determined that the residual memory space reporting mode has been set, system controls goes to step S4307.
In step S4307, a number of remaining sheets of pictures which can be photographed further and a remaining period of time operable further in each recording mode (still picture mode, voice mode, etc) are computed from a residual memory space available at the current point of time (capacity D). Then determination is made as to whether the current mode is the earphone mode or not (S4308), and if it is determined that the current mode is not the earphone mode, system control goes to step S4309, and if it is determined that the current mode is the earphone mode, system control goes to step S4310.
In step S4309, as shown in Table 1, either one of the speaker 120 or the earphone jack 122 is enabled as a voice output means according to whether an earphone has been connected to the earphone jack 122 or not. Then the number of remaining sheets and the remaining period of time (namely capacity D) are communicated in voice via the enabled speaker 120 or earphone jack 122 (S4311), and system control goes to step S4304.

In step S4310, as shown in Table 2, only the earphone jack 122 is enabled as a voice output means regardless of whether an earphone has been connected to the earphone jack 122 or not. Then the number of reamining sheets and the remaining period of time (namely the capacity D) are communicated in voice via the earphone jack 122 (S311), and system control returns to step S4304.

As described above, in Embodiment 13, as it possible to specify the earphone jack 122 as a voice output means by setting the earphone mode, even in a case, for instance, where the mode for recording voices and the residual memory space reporting mode have been specified simultaneously, it is possible to record only voices as an object for recording. Namely, even in a case where the residual memory space reporting mode is selected while recording voices in a conference or others, it is possible to prevent voice communications for reporting the residual memory space and voices as an object for recording from being recorded simultaneously, which improves convenience in use.
In the digital still video camera according to Embodiment 14, in a case where the residual memory space reporting mode is set, it is possible to select a recording mode for which a residual memory space for recording is communicated, and voice output for a residual memory space is provided only in the selected recording mode.
It should be noted that configuration of the digital still video camera according to Embodiment 14 is the same as that in Embodiment 12 and description is made herein only for different portions.
Then system initialization is finished, and if there has occurred no error, the system is enabled (S4403).
When the system is enabled, a user selects a mode through the operation display section 116 and inputs the selected mode, when the CPU 113 executes operation (1) to (5) in the selected mode (S4404). Although detailed description is not made herein, the recording mode is selected by setting the main switch 1401 in power ON (recording mode), and the deleting mode, the residual memory space reporting mode, and the reporting select mode (a mode in which any among a plurality of reporting modes is selected for reporting the residual memory space) are set as the power is turned ON (regenerating mode) and the mode selection is executed. Also the end mode is selected by setting the main switch 1401 in power OFF and is executed before actually the power is disconnected.
It should be noted that the capacity D=Capacity A−Capacity B+Capacity C.
Then, determination is made as to whether system operation is to be terminated or not (S4405), and if it is determined that the system operation is to be terminated, the processing is terminated. If not, determination is made as to whether the residual memory space reporting mode has been set or not (S4406), and if it is determined that the residual memory space reporting mode has not been set, system control returns to step 4404, and if it is determined that the residual memory space reporting mode has been set, system controls goes to step S4407.
In step S4407, a number of remaining sheets of pictures which can be photographed further and a remaining period of time operable further in each recording mode are computed from a residual memory space available at the current point of time (capacity D) according to the recording mode selected and set in the reporting select mode. Then the number of remaining sheets and the remaining period of time (namely capacity D) are communicated in voice through the speaker 120 (S4408), and system control returns to step S4404.
In Embodiment 14, as described above, a residual memory space can be communicated in voice only in the recording mode selected and set in the reporting select mode. For this reason, in a digital still video camera having a number of complicated recording modes, a user can save a time required for communicating in voce a residual memory space for recording by setting a recording mode frequency used by the user.
In the digital still video camera according to Embodiment 15, it is possible to specify conditions for reporting a residual memory space for recording in the memory card 103, and in a case where the conditions for reporting have been specified and also a residual memory space in the memory card 103 satisfies the conditions for reporting above, the residual memory space is communicated in voice.
It should be noted that, as configuration of the digital still video camera according to Embodiment 15 is the same as that in Embodiment 12, description is made only for different portions.
Then system initialization is finished, and if there has occurred no error, the system is enabled (S4503).
When the system is enabled, a user selects a mode through the operation display section 116 and inputs the selected mode, when the CPU 113 executes operation (1) to (5) in the selected mode (S4504). Although detailed description is not made herein, the recording mode is selected by setting the main switch 1401 in power ON (recording mode), and the deleting mode, the residual memory space reporting mode, and the reporting condition setting mode (a mode in which conditions for reporting a residual memory in the memory card 103 is specified) are set as the power is turned ON (regenerating mode) and the mode selection is executed. Also the end mode is selected by setting the main switch 1401 in power OFF and is executed before actually the power is disconnected.
It should be noted that the capacity D=Capacity A−Capacity B+Capacity D.
As the limit memory space, it is possible to set a percentage (x %) against the total recording capacity of the memory card 103, or to set a remaining byte (xMB: mega byte), a number of remaining sheets (x sheets), a remaining period of time (x hours), and remaining times (x times).
Then, determination is made as to whether system operation is to be terminated or not (S4505), and if it is determined that the system operation is to be terminated, the processing is terminated. If not, determination is made as to whether the residual memory space reporting mode has been set or not (S4506), and if it is determined that the residual memory space reporting mode has not been set, system control returns to step 4504, and if it is determined that the residual memory space reporting means has been set, system controls goes to step S4507.
In step S4507, a number of remaining sheets of pictures which can be photographed further and a remaining period of time operable further in each recording mode are computed from a residual memory space available at the current point of time (capacity D) according to the recording mode selected and set in the reporting select mode. Then determination is made as to whether the limiter flag has been set or not (S4508), and if it is determined that the limiter flag has not been set, system control goes to step S4510, and the number of remaining sheets and the remaining period of time (namely capacity D) are communicated in voice through the speaker 120, and then system control returns to step S4504.
On the other hand, if it is determined in step S4508 that the limiter flag has been set, determination is made as to whether a residual memory space for recording at the current point of time (capacity D) has reached the limited memory space or not (S4509), and if it is determined that the residual space memory D is lower than the limit memory space, a number of remaining sheets and a remaining period of time (namely the residual memory space D) are communicated in voice, and system control returns to step S4504. Also if it is determined that the residual memory space is not less then the limit memory D, system control returns to step S4505 immediately.
As described above, in Embodiment 15, as it is possible to set a timing for reporting a residual memory space by setting the conditions for reporting, a residual memory space can be communicated in voice at a timing desired by a user.
Further FIG 13 is a block diagram showing the digital still video camera according to Embodiment 16. Details of
Configuration in Embodiment 16 is the same as that shown in
Although not shown herein, the operation display section 116 comprises various types of button and switch and a display panel, and the various types of button and switch include a main switch of a basic body of the camera, a self mode button for setting a mode (self mode) for photographing with a self timer, a zoom lever for changing a size of an object to be photographed within a finder, a photographing mode setting button, and a release button which is a two-stage button starting operation of the auto-focus mechanism when pressed down by half and also starting recording into the memory card 103 when fully pressed down.
Namely when the release button (shutter) is pressed down by half, an object to be photographed caught by the lens unit 104 is displayed on the LCD 119, and when the release button is fully pressed down, the displayed image is recorded into the memory card 103. It should be noted that a size of an image recorded into the memory card 103 in the normal mode is fixed at H (pixels) in the vertical direction×W (pixels) in the horizontal direction regardless of whether image compression is to be executed.
With the configuration as described above, next description is made for operations in each section of the digital still video camera according to Embodiment 16 with reference to the related flow charts and explanatory views.
At first, description is made for operations for setting a small memory space photographing mode with reference to the flow chart in FIG. 46. Setting is executed, when the digital still vide camera has been enabled, by pressing the photographing mode setting button in the operation display section 116. In step S4601, a mask type is selected from various types of mask previously prepared as shown in
Then description is made for photographing in the small memory space photographing mode with reference to the flow chart shown in FIG. 48. Herein description is made on the assumption that the mask shown in
At first, in step S4801, when the release button (shutter) is pressed down by half, the mask corresponding to a number selected from the MEM 114 (Refer to
Herein a photographer executes positioning for the object to be photographed displayed within the mask (S4804), and when the desired object is positioned within an area where recording can be executed (“Yes” in determination in step S4805), the release button (shutter) is fully pressed down (S4806), the image within the mask (Refer to
Next description is made for operations for regenerating an image photographed in the small memory space photographing mode with the flow chart shown in FIG. 50. At first, when an operating mode for regenerating and displaying an image is selected in step S5001, in step S5002, determination is made as to whether a type number for a mask has been added to the image data to be regenerated and displayed or not. Herein, if it is determined that a type number has not been added to the header, it is determined that the image data is for an image photographed in the ordinary photographing mode, and ordinary operations for regeneration and display are executed.
In step S5002, if it is determined that a type number for a mask has been added to the header of the image data to be regenerated and displayed, mask information corresponding to the type number is read out from the MEM 114 (step S5003), and the image is regenerated and displayed according to said mask information (step S5004).
