This application is a reissue application for U.S. Pat. No. 5,940,121 issued Aug. 17, 1999 on U.S. Ser. No. 08/803,548 filed Feb. 20, 1997.
This invention relates to hybrid camera systems capable of capturing both electronic and photographic film images, and more particularly to a hybrid camera system, method and apparatus for selectively reviewing and creating album formats for film images captured by the camera.
Hybrid cameras that concurrently capture both photographic film and electronic images of a scene are shown in U.S. Pat. No. 4,716,470, which describes a hybrid camera containing systems for capturing respective images onto a photographic film and an electronic imaging element, such as an area array of charge coupled devices (CCD). The camera has an optical system, in combination with a shutter release mechanism, allowing a still image to be captured by the photographic film and the electronic imaging element, either sequentially using a single optical system or essentially simultaneously using parallel optical systems.
Hybrid cameras also may include a display, usually a liquid crystal display (LCD) provided in the rear of the camera which allows the user to either review or preview the image. The user then may opt to process the captured photographic image based on the still electronic image, or in the review mode, the user may alternately decide not to process the reviewed image as captured on the photographic film. Such a hybrid camera is described in U.S. Pat. No. 4,742,369 in which the user is given an option as to whether to preview a selection after electronic image capture or review after the photographic and electronic images have been captured. In other examples of the prior art, instructions can be given as to whether exposure control, illumination, etc., should be augmented based on the still image, therefore providing guidance to the photo finisher. In commonly assigned U.S. Pat. No. 4,949,117, an image verifier camera is described in which the electronic sensor is used to control the recording of the image onto photographic film. The user is allowed to select those frames captured by the camera which are to be processed and printed by use of the electronic display. Additionally, these cameras can also record data relating to how the selected frame(s) are to be printed; that is, information relating to cropping, zoom, and exposure. Each of the above examples are indeed useful for previewing an electronic image to determine whether a silver halide (conventional photographic) image of interest should be taken, or alternately, if the image has already been taken, whether or not instructions should be given to the photo finisher to modify processing or providing cropping, enlargement, etc.
A more recent development in the photographic field, commonly referred to as the Advanced Photographic System (APS), includes cameras sold under the trademark Advantix, by the Eastman Kodak Company. These camera utilize a photographic filmstrip having a transparent magnetic layer including plural longitudinal magnetic tracks on the border of the filmstrip which begin and end within individual frames. Each magnetic track is dedicated to the reading and writing of data in a predetermined format, the data relating to the corresponding frame, for easy access by a user or photo finisher. Each user has the capability to read and/or write information in self-identifying data in the corresponding tracks. An example of this format is contained in U.S. Pat. No. 5,229,810, which hereby is incorporated by reference as part of the disclosure of the present invention. The use of the magnetic tracks has found a number of useful applications, particularly relating to the photoprocessing field. For further information on cameras having magnetic tracks, see U.S. Pat. No. 5,023,635, which describes a camera having a dual capture system which includes a video monitor which is used in writing photo finishing instructions onto the magnetic track of the film.
Schemes have been proposed for magnetically recording on the photographic film information useful in organizing photographs in an album. For example, information recorded may represent a series of album pages which have been preselected by a previewer and within onto the magnetic layer of the film, thereby allowing the user to select both the image and the desired page as well as the position of the print on the page of interest. However, the recording is made upon processing and is placed on the film upon return of the photographic order from the film processor. One of these album organization schemes is disclosed in U.S. Pat. No. 5,274,418, which describes optically encoding information onto a filmstrip for orienting an array of processed images onto an album page. This patent, however, does not describe a camera having an electronic display or viewfinder to review prints to orient the captured images for presentation within an album format.
The creation of a meaningful album of photographs is also enhanced by a system embodying the invention which enables combination of textual information, such as screen-related data or other information, in addition to date stamping, with the photographic prints selected for album formatting in order to provide text on the same album pages as the prints of a processed order.
A primary object of the present invention is to provide an improved system which increases the capability of hybrid cameras.
Another primary object of the present invention is to provide an improved hybrid camera system which allows a user to select images captured using a hybrid camera and determining a specific page and orientation onto which a selected image will be produced in an album-like format.
Another primary object of the present invention is to provide an improved hybrid camera system which allows a user to select a particular image in a particular order for composing the album pages which can be composed automatically by the photo processor.
A further object of the present invention is to provide an improved hybrid camera having the ability to magnetically record text annotation via voice recognition, keyboard, or other input means and to transfer the information so that the processor can create an album where the annotation is combined with the prints.
Briefly described, a hybrid camera system embodying the invention has image capture means, such as an electronic sensor and an optical and film transport mechanism, which simultaneously capture an optical image onto a photographic film and corresponding electronic image on the electronic sensor within a camera housing.
A display means can display the image captured electronically by the image capture means. In order to facilitate organization of prints made from the film into an album, input means are operated by the user while observing the electronic image to selectively input album related instructions relating to the image displayed. The instructions can provide information or relate to the orientation and formatting of the prints in an album or album-like format.
In a preferred embodiment, the film has a magnetic recording media and the user selections are recorded directly onto the magnetic media allowing the selections to be read by photoprocessing apparatus capable of digitally reproducing the film images selected in the selected order and automatically composing the album pages to comprise the photographing order.
The invention also provides a method for selectively captured images in an album-like format using a hybrid camera having a display for displaying a captured image. In carrying out the method an image is simultaneously captured onto a photographic film and electronic imager or sensor contained with the camera. The film has a magnetic media for receiving information thereon. The captured image is then displayed. Thereafter, album related data is selectively inputted onto the magnetic media of film corresponding to the displayed image.
An advantage of the present invention is to provide for automatic creation of an album which satisfies the need to organize photographs without the necessity of two separate events, a first picture taking event and a later album making event. An album making event can become burdensome because the specific details of the picture taking event have become lost over time, the camera system of the present invention on the other hand, allows for capturing an image, previewing the image in an album format, supplying orientation and other formatting instructions for encoding onto the magnetic track, and selectively providing text annotation corresponding to the previewed image.
Another advantage of the present invention is that all of the proceeding steps can be done by the user and at the camera level, as opposed to having some of the steps performed at the photo finisher level. Another advantage of the present invention is that customization of images captured by the camera (i.e. orientation, fonts used, etc.) in an album-like format can be done at the time of the picture taking event using the camera and by writing directly onto the film. The photographs can then be produced at a later date by the photo finisher without further intervention of the photographer required
Other objects, features, and advantages will be apparent from the following Detailed Description of the Invention, when read in conjunction with the accompanying drawings.

This invention is now described in relation to a preferred embodiment using a specific non-single lens reflex (NSLR) hybrid camera. It will be apparent from the following discussion, however, that the teachings of the present invention can extend to SLRs, as well as other known cameras, including digital cameras, which can also be adapted in a similar fashion.
According to this embodiment, a pair of electronic displays 20,24 which do pertain to the present invention are adjacently provided on the rear side 22 of the camera body 12. The first electronic display 20 is a flat color liquid crystal display (LCD) screen, such as Model LQ3GN31, manufactured by Sharp Electronics, Inc., preferably capable of presenting high resolution color images. The second adjacent electronic display 24 according to this embodiment is a black and white single liquid crystal display (LCD) 24 capable of displaying single line text. As described below, each of the imaging the textual displays 20,24 also present specific information as the operator exercises specific functions of the camera 10. The details regarding the workings and details of LCDs in general are already commonly known in the field and do not form an essential part of the present invention. Therefore, further discussion is not required, except as needed.
Referring to
For purposes of background, the film cartridge 180, which is received in a cartridge receiving chamber 192 of the camera body 12, includes a light-lock door (not shown) which is movable between a closed position, sealing the cartridge in a light-tight fashion, and an open position for allowing the filmstrip 182 to exit the cartridge through the light-lock door. Once the door is opened, the filmstrip 182 is thrust from the confines of the cartridge by rotation within the cartridge 180 of a spool 194 around which the filmstrip has been wound. The filmstrip 182 is then thrust along a film travel path, shown as arrow 195 and stopped across an exposure gate 198 which allows ambient light to impinge on a frame 190 of the photographic film. After exposure, the film is advanced to an oppositely disposed film roll chamber 200 having a take-up spool 202 onto which the exposed film 204 is wound. When all frames have been exposed, a film rewind mechanism (not shown) rewinds the exposed film 204 from the take-up spool 202 back onto the confines of the film cartridge 180, as is conventionally known. The workings themselves of the so-called “thrust-type” cartridges, as well as those of the film advance and take-up mechanisms are commonly known in the prior art and do not form a basis for the present invention.
Referring to
Similarly, a solid-state imaging element or imagery 34, such as a charge coupled device (CCD), is adjacently and fixedly positioned by known means within the interior of the camera body 12 to receive an optical image as focused by a separate focusing lens 38 through a shutter aperture 36 along a parallel optical axis 44. According to this embodiment, and as described below, each of the shutter apertures 32, 36 are opened essentially simultaneously by the depression of the shutter release button 18.
The specific positioning of the electronic imager 34 and the workings of the shuttering mechanism (not shown) are not necessarily critical to the workings of the present invention, provided the dual optical systems are configured and aligned to capture essentially the same scene as viewed through the optical viewfinder 13. A similar system is described in commonly assigned U.S. Pat. No. 4,949,117, which is hereby incorporated by reference into the disclosure of the present invention. In addition, it is also contemplated for purposes of the present invention that a single optical path can be utilized in lieu of using a pair of optical systems by using a beamsplitter or other similar device. Such an arrangement is described in U.S. Pat. No. 4,716,470 which is hereby incorporated by reference into the disclosure of the present invention. Other salient features of the present camera 10 will now be described.
Referring to the block diagram of

An example of a useful electronic display control block 88 pertaining to the imaging display 20 is illustrated in FIG. 9. As is known in the field, an electronic liquid crystal display requires a video signal input, as opposed to computer LCDs which typically recognize digital signal input. Therefore, CCD driver circuitry 132 allows an electronic image to be captured by the photodiodes (not shown) of the image sensor 34, having appropriate analog signal processing circuitry and amplifying circuitry 134. A corresponding analog signal is converted to a digital signal by an analog-to-digital converter 136 and processed by a digital signal processor 138 prior to storage in a digital memory 140 using address generators 156. Additional conversion of the digital signal by a digital-to-analog converter 142 and NTSC converter 144 allows an NTSC video signal to be transmitted through signal conditioning electronics 146 for display by the LCD 20, preferably having a powered backlight 148 as is commonly known. A battery 150 powers microprocessor 68 via a voltage regulating block 152, the microprocessor also being interconnected to a high speed slave timing generator 154. Additional details relating to the processing of the image signal are commonly known in the field, such as described in U.S. Pat. No. 4,949,117.
Referring to FIG. 3(a), and according to this particular embodiment, a series of control switches 50,52,54 are provided on the rear side 22 of the camera body 12 preferably adjacent the flat imaging and textual displays 20, 24, for controlling each of the display and input functions of the camera 10. Upon the simultaneous image capture onto the electronic imager 34, and the photographic film 182, and electronically captured scene 48, much the same as that seen through the optical viewfinder 13, is displayed on the color imaging display 20. The user, as described in greater detail momentarily, reviews the displayed image 48 and selectively determines whether or not the image should be printed as a part of an album page, as well as the specific features and format of the selected images as prints on the album page. This is accomplished by responding to a series of text prompts through feedback supplied through the text display 24. Confirmation of a selection is done by depression of a selection control button 50, while respective increment and decrement buttons 52 and 54 are used to scroll through a scripted menu of choices (partially shown) which is visible in the text detailed 24. Referring briefly to FIG. 3(b), it will become apparent to those of ordinary skill in the field that a single composite display 64 may be alternately utilized in lieu of the pair of dual imaging and textual displays 20,24. Such a composite display would allow text annotation information to be added to the displayed electronic image of interest.
Initially, a corresponding user prompt message is transmitted by the microprocessor 68 through similar circuitry to the textual display 24, as shown more clearly in FIG. 3(a). The series of default prompts is relate to the automatic album making function as displayed by the textual display 24 in a series of discrete fields. According to this embodiment, the initial display includes a query field 56, a query response field 58, an image sequence number 60 and a page break field 62, respectively, sequentially disposed across the single line text display 24. According to the present embodiment, the initial default parameters which are displayed by display 24 indicate to the user that the displayed image will be placed in an album. In addition, the corresponding frame number of the filmstrip 182 is assigned as the album order number with no defined page breaks as in each of the respectively displayed fields.
According to step 94 of
If the automatic album feature is selected, and according to step 96, the scrolling buttons 52,54 allow movement through a menu of available choices relating to the orientation and format of the displayed prints on album pages. These buttons can be used to prompt a set of alternate menu choices, as programmed into the logic of the microprocessor 68 in a commonly known manner. A convenient menu logic for the textual information according to this embodiment is a series of choices which are conveyed similarly to those used in a Microsoft Windows environment. One specific example of a formatting option is illustrated in
According to step 98, and after all of the album input parameters have been selected for a displayed image by the user according to the menu, depression of the control button 50 will trigger the microprocessor 68 to engage the annotation feature and the user will be initially prompted for input.
It should be noted that a number of different means for inputting appropriate text information can be utilized. For example, U.S. Pat. No. 4,742,369 describes a voice recognition system for a camera that can be modified to provide the necessary input. Alternately, the 4,742,369 patent also describes an alphanumeric keypad which can be used in conjunction with the present invention according to the annotation input path 80 shown in FIG. 5. Cameras such as the Ricoh RZ-105 also include a keypad inputting feature. The specific input device is not critical to the present invention; therefore, other similar devices can be used.
An initial text display 24 is depicted in FIG. 4. As shown, and depending on the logic contained in the microprocessor 68, a variety of menu options are available. Accoridng to the present embodiment, the font style and size of the annotated text information that the photo finisher will use on the selected album pages can be preselected in a font control field 66 by the user and written onto the magnetic layer 184,
According to step 100, the input annotation data is then written onto the magnetic tracks 186 of the contained photographic filmstrip 182 using output data path 84 and the interface magnetic head circuitry 86 of
According to step 102, and if no textual information was written onto the filmstrip 182, or if annotation is completed, then the filmstrip can be advanced using the film advance mechanism (not shown), the features of which are commonly known in the field. Alternately, if no annotation was selected, or if the automatic album feature was not selected, then the film can be advanced.
According to step 104, and once the filmstrip has been advanced to the next frame, the LCD information display indicates the camera 10 is ready for another imaging sequence and steps 90-104 are repeated. Depending on the amount of memory available to the microprocessor 68, the user can repeatedly scroll through the displayed images stored in memory prior to unloading the film cartridge 180 from the camera body 12. For example, the microprocessor 68 can be programmed to store all captured images, whether or not album related data has been correspondingly written onto the film 182.
FIGS. 7(a) and 7(b) depict flow diagrams of the logic used by the microprocessor 68 to automatically print the album pages during the photofinishing process. After the photographic film 204 has been rewound into the confines of the film cartridge 180, and removed from the camera body 12, the film cartridge is delivered to a photo processor. A high resolution scanner (not shown) is preferably used to scan the negatives. Prior to or during the scanning process, the designated magnetic tracks 186 of the exposed film 204 are read by the photofinishing apparatus (not shown) to determine if the automatic album feature is present. According to step 110, and if the automatic album feature is not present on the magnetic layer 184 of the exposed photographic film 204, then standard photofinishing will occur. According to step 112, and if the automatic album feature is detected, then photofinishing apparatus, (not shown) connected to a computer network (not shown), creates a folder/path on an attached file server. The images, annotated text, and attached album directions are then digitally scanned according to step 114. According to step 116 and after the images have been scanned, the photofinishing apparatus creates an Image Pack for albuming and according to step 118 transfers it along with the album composition data to the newly created folder on the file server. According to step 120, a workstation (not shown) also attached to the file server executes software that takes the image pack along with the album composition data to display on the workstation's video display terminal (VDT) (not shown). According to step 122, the workstation operator then inspects the pages and corrects for any orientation problems per step 124. If any orientation problems are present, then they are fixed according to step 126. Otherwise, finished album pages are printed when the soft-display VDT looks appropriate.
While the invention has been described with reference to a preferred embodiment, it will be appreciated that various modifications can be made without departing from the spirit and scope of the invention. Such modifications are intended to fall within the scope of the appended claims.
