This application is a Reissue of U.S. Pat. No. 7,006,247, issued Feb. 28, 2006, which issued from U.S. application Ser. No. 09/716,958, filed Nov. 22, 2000, which claims priority to Japanese Patent Application No. 2000-133635, filed on May 2, 2000.
1. Field of the Invention
The present invention is related to an image processing apparatus which may be applied to various sorts of image output systems such as a facsimile, a copying machine, and a printer.
2. Description of the Related Art
Image output apparatuses known as facsimiles, copying machines, and printers are manufactured in composite forms by digitally combining various functions thereof. On the other hand, these image output apparatuses are gradually connectable to networks such as the Internet and an intranet. In addition, data transfer speeds via networks are gradually increased. On the other hand, while hard disks and semiconductor memories are manufactured in low cost and with large storage capacities, better environments may be established under which image data are distributed/stored in relatively easy manners. For instance, Japanese Laid-open Patent Application No. Hei-11-192760 discloses the following charge amount discounting method. That is, in this disclosed apparatus, with respect to the images outputted on the paper and also the images transmitted by using the networks and the FAX (facsimiles), the images such as advertisement information are added, so that the charge amounts for the users are discounted.
However, in the conventional technique described in the above-explained publication, since the images such as the advertisement information are uniformly added, there is such a possibility that when the image to be outputted by the user corresponds to the black/white image, the color image is added to this black/white image. Normally, there are differences in output speeds in the case that a color image is outputted, whereas a black/white image is outputted. As a consequence, if a color image is added to an input image although a user intends to output a black/white image, then an output speed is lowered due to the added color image. As a result, there is such a risk that productivity is considerably lowered.
Also, generally speaking, in a charging system for calculating a charge amount when an image is outputted, a charge amount shared by a user when a color image is outputted is different from a charge amount shared by the user when a black/white image is outputted. As a consequence, the following problem may occur. That is, even when an image which is outputted by a user corresponds to a black/white image, if an added image corresponds to a color image, then this charging system simply calculates a charge amount for the color image.
Furthermore, the following case may be conceived. In such an output apparatus capable of outputting only a black/white image after a color image has been added to an input image, only such a black/white image is merely outputted. In such a case, in accordance with the conventional technique described in the above-explained publication, the following problems may be conceived. That is, since the image formed for the color image is black/white-converted, certain colors are dropped out, and color differences cannot be discriminated from each other, so that the content of the image cannot be correctly informed.
The present invention has been made to solve the above-explained problems, and therefore, has an object to provide an image processing apparatus capable of adding an additional image to an input image in response to a characteristic of this input image, and capable of outputting an image without deteriorating productivity when an image is outputted, and also capable of avoiding dropping of a content of an additional image.
Another object of the present invention is to provide an image processing apparatus capable of calculating a charge amount in a proper manner even when a charge amount is calculated, and also even when an additional image is added.
An image processing apparatus, according to the present invention, is featured by comprising: additional image storage means for storing thereinto one, or more additional images in response to a characteristic of an input image; judging means for judging the characteristic of the input image; and synthesizing means for adding an additional image corresponding to the characteristic of the input image stored in the additional image storage means to the input image in accordance with the judgment result made by the judging means. For instance, while the additional image storage means stores thereinto both a color additional image and a black/white additional image, depending upon such a fact as to whether the input image corresponds to a color input image, or a black/white input image, the additional images to be added to the input image can be switched. As a result, when the input image is the black/white image, the black/white image can be added to this input image. This is different from the conventional image processing apparatus in which only the additional image is the color image, so that productivity is not lowered. Also, as to the image to be added, since the additional image corresponding to the black/white image is added to the black/white input image, dropping of the content of the additional image can be prevented.
Also, in order to accept such a case that there is no such an additional image corresponding to a characteristic of an input image, image converting means for converting a characteristic of an additional image may be employed. For instance, while a color additional image is stored in the additional image storage means, when a black/white image is inputted as an input image, the color additional image is converted into a black/white additional image by the image converting means, and then, this converted black/white additional image may be added to the input image. Also, in this case, for example, when the input image is the black/white image, the black/white image can be added to this input image. This is different from the conventional image processing apparatus in which only the additional image is the color image, so that the deterioration of productivity can be avoided.
Otherwise, when an additional image corresponding to the characteristic of the input image is not stored, it is possible to issue such an instruction that this additional image is outputted while having a characteristic corresponding to the characteristic of the input image, and also add the additional image to the input image. For example, while a color additional image is stored in the additional image storage means, when a black/white image is inputted as an input image, the color additional image stored in the additional image storage means is added to the input image in connection with a command for outputting the color additional image as a black/white image. As a consequence, when the image to which the additional image is added is actually outputted, both the input image and the additional image can be outputted as the black/white images. This is different from the conventional image processing apparatus in which only the additional image corresponds to the color image, so that lowering of the productivity can be prevented.
Furthermore, when a charge amount is calculated, as explained above, since the additional image in correspondence with the characteristic of the input image is added, if the charge amount calculation is performed in accordance with the characteristic of the input image, then the charge amount can be calculated in a proper manner. As a consequence, even when the color additional image is added to the black/white image, the charge amount for the user can be handled as the charge amount for the black/white image. Otherwise, the charge amount calculation may be carried out in accordance with the judgment result of the input image by the judging means. Alternatively, the charge amount may be varied, depending upon such a condition as to whether or not the additional image is added.
Now, a description will be given in more detail of preferred embodiments of the invention with reference to the accompanying drawings.
The color judging unit 2 judges as to whether each of output pages is color, or black/white with respect to an input image. When such a portion other than a black/white portion is present even in an output page, this color judging unit 2 can judge that the input image thereof is a color image.
The additional image storage unit 3 can store thereinto one, or more additional images which are added to the input image. In the example of
The image synthesizing unit 6 owns the following function. That is, in response to a judgment result made by the color judging unit 2, this image synthesizing unit 6 adds to an input image, any one of a color additional image stored in the color image storage unit 4 and a black/white additional image stored in the black/white storage unit 5. For example, in such a case that the color judging unit 2 judges that an inputted image is a color image, the image synthesizing unit 6 can add the color additional image stored in the color image storage unit 4 to this input color image. For example, in such a case that the color judging unit 2 judges that an inputted image is a black/white image, the image synthesizing unit 6 can add the black/white additional image stored in the black/white image storage unit 5 to this input black/white image. Apparently, even when an inputted image is a black/white image, the image synthesizing unit 6 may add the color additional image to this input black/white image. In a process operation for adding an additional image to an input image, for example, when output image data owns the raster format, the input image may be synthesized with the additional image. Also, for instance, when output image data owns the PDL format, such a command may be transferred to the image output unit 7, by which both the input image and the output image are imaged into the same page.
The image output unit 7 forms an image in accordance with such image data obtained by adding an additional image to an input image by the image synthesizing unit 6. Alternatively, the image output unit 7 may output this image data to, for example, an external network. Even when an image is formed in this image output unit 7, and also even when an image is formed via the external network in another apparatus, there are many possibilities that an efficiency is lowered when a color image is formed, as compared with that when a black/white image is formed. However, since the image synthesizing unit 6 adds the additional image to the input image, depending upon such a fact that this input image corresponds to either the color image or the black/white image, for instance, if the black/white additional image is added to the black/white input image, then the black/white image can be formed in a higher efficiency. Thus, lowering of productivity can be suppressed, which is caused by that only the color additional image is added to the black/white input image.
The control unit 8 controls an entire operation of the image processing apparatus. In this case, this control unit 8 also preforms a reading control operation of an additional image with respect to the additional image storage unit 3 in accordance with the judgment result derived from the color judging unit 2, and further, executes an adding control operation of an additional image to an input image in the image synthesizing unit. Alternatively, as apparent from the foregoing description, these control operations may be carried out in the respective units. Furthermore, the control unit 8 may perform a control operation related to a charging operation (charging system). The charging operation may be carried out based upon, for example, a characteristic of an image outputted from the image output unit 7. As an example, this charging operation may be performed, depending upon such a fact that an output image corresponds to either a color image or a black/white image. Alternatively, the charging operation may be carried out based upon a judgment result of a characteristic of an input image judged in the color judging unit 2. For example, this charging operation may be carried out, depending upon such a fact that an input image corresponds to either a color image or a black/white image. Alternatively, the image processing apparatus may be arranged in such a selectable manner as to whether or not an additional image is added from an external source. In response to this instruction, the control unit 8 may control the image synthesizing unit 6. A charge amount calculated in the charging operation may be made different from each other, depending upon such a fact as to whether or not an additional image is added. Furthermore, the image processing apparatus may be alternatively arranged in such a way that a color additional image is always designated as the additional image, or a black/white additional image is always designated as the additional image.
In the flow chart of
On the other hand, in such a case that the relevant page of the input image corresponds to the black/white page which is judged by the color judging unit 2, the image synthesizing unit 6 adds a PDL command to the data of the input image which is described by the PDL format, and then outputs PDL data of an image of this page to the image output unit 7 at a step S13. This PDL command is used to add the black/white additional image stored in the color image storage unit 5.
At a step S14, a check is made as to whether or not pages of the input image up to a final page have been outputted. When the pages up to the final page have not yet been outputted, the process operation is returned to the previous step S11 in order to execute the image processing operation as to the next page. As previously explained, the above-described image processing operation is repeatedly carried out as to all of the pages contained in the input image.
As previously described, in such a case that the output apparatus is an image forming apparatus such as a printer, a time duration required to form a color image becomes several times longer than a time duration required to form a black/white image. As previously explained, since the black/white additional image is added to the black/white input image, the additional image can be added, while the productivity is not lowered when the black/white image is outputted.
Also, in this first embodiment, since the color additional image and the black/white additional image are separately saved, as represented in
For instance, in
It should also be noted that
In the example shown in
In such an alternative case, even when an input image is a black/white image, an image outputted from the image synthesizing unit 6 becomes a color image. However, as shown in
The black/white converting unit 9 converts a color additional image stored in the color image storage unit 4 into a black/white additional image. In response to a judgment result made by the color judging unit 2, the image synthesizing unit 5 adds to an input image, any one of the color additional image stored in the color image storage unit 4 and the additional image which is converted into the black/white additional image by the black/white converting unit 9.
In the flow chart of
On the other hand, in such a case that the relevant page of the input image corresponds to the black/white page which is judged by the color judging unit 2, the image synthesizing unit 6 receives the black/white additional image from the black/white converting unit 9 at a step S23. This black/white additional image is produced in such a manner that the color additional image stored in the color image storage unit 4 is converted into the black/white image in the black/white converting unit 9. Then, this image synthesizing unit 6 adds such a PDL command to the data of the input image written by the PDL format, and then outputs PDL data of an image of this page to the image output unit 7. This PDL command is used to add the received black/white additional image.
At a step S24, a check is made as to whether or not pages of the input image up to a final page have been outputted. When the pages up to the final page have not yet been outputted, the process operation is returned to the previous step S21 in order to execute the image processing operation as to the next page. As previously explained, the above-described image processing operation is repeatedly carried out as to all of the pages contained in the input image.
Since the above-explained operation of this image processing apparatus according to the second embodiment is carried out, for instance, as shown in
It should also be noted that since the charging system control operation of the second embodiment can be carried out in a similar manner to that of the first embodiment, descriptions thereof are omitted in this embodiment.
In this third embodiment, the image synthesizing unit 6 switches one instruction and another instruction in response to a judgment result obtained by the color judging unit 2 as a PDL command by which a color additional image stored in the color image storage unit 4 is added to an input image. In one instruction, such a command for adding a color additional image is added to the input image. In another instruction, such a command for adding a black/white additional image is added to the input image. As a result, for example, when an image described in the PDL format is interpreted in either the image output unit 7 or an externally-provided image forming apparatus, either the color additional image or the black/white input image is added to this input image in response to the PDL command.
On the other hand, in such a case that the relevant page of the input image corresponds to the black/white page which is judged by the color judging unit 2, the image synthesizing unit 6 adds a PDL command to the data of the input image which is described by the PDL format, and then outputs PDL data of an image of this page to the image output unit 7 at a step S33. This PDL command is used to add the black/white additional image stored in the color image storage unit 5.
At a step S34, a check is made as to whether or not pages of the input image up to a final page have been outputted. When the pages up to the final page have not yet been outputted, the process operation is returned to the previous step S31 in order to execute the image processing operation as to the next page. As previously explained, the above-described image processing operation is repeatedly carried out as to all of the pages contained in the input image.
When the image having the PDL format is interpreted which is produced by executing the above-explained operation of the image processing apparatus according to the third embodiment, for example, as shown in
It should also be noted that since the charging system control operation of the second embodiment can be carried out in a similar manner to that of the first embodiment, descriptions thereof are omitted in this embodiment.
In the above-described first to third embodiment, such an example is described. That is, either the color additional image or the black/white additional image is added, depending upon such a fact as to whether the input image corresponds to the color image, or the black/white image. As previously explained in the charging system, for example, the charge amounts may be made different from each other, and also the image forming durations may be made different from each other by forming either an image in two colors or an image in three colors. In such an alternative case, while additional images corresponding to these images are stored in the additional image storage unit 3, converting units are employed in accordance with these arrangements. Otherwise, the PDL command may be added, by which the relevant images may be formed. In the case that there are many sorts of additional images, several additional images are previously prepared, whereas when there is no corresponding additional image, the additional image stored in the additional image storage unit 3 may be converted into such a desirable additional image similar to the second embodiment mode. Alternatively, a PDL command may be added so as to output the relevant additional image similar to the third embodiment mode.
Also, in the above-described example, while the color is considered as one of the characteristics of the input image, the corresponding additional image is added to the input image. However, the present invention is not limited to this example, but may be applied to other examples. For example, as the characteristic of the input image, the corresponding additional images may be added to the input images with respect to each of various characteristics such as resolution, and drawing objects, i.e., a text and an image. Also, the corresponding additional images may be added to the input images with respect to each combination of plural characteristics. Apparently, as to the charging system, the charge amounts may be calculated in response to these characteristics. For example, when a test printing operation with low resolution is carried out, a charge amount may be set to low cost, whereas when a printing operation with a high image quality is carried out, a charge amount may be set to high cost. This charge amount setting operation is determined by checking as to whether or not an additional image is added to an input image.
As apparent from the foregoing description, since the additional image can be added to the input image in correspondence with the characteristic of this input image, the image processing apparatus of the present invention can output the image in the following manner, while productivity during the image output operation is not lowered. That is, for example, when the time duration required to form the black/white image is different from the time duration required to form the color image, the additional images fitted to the respective characteristics may be added to the input image. Also, since the additional images fitted to the respective characteristics are prepared, such a problem can be prevented. That is, for example, a color additional image is outputted as a black/white image, so that a content of this color additional image is dropped.
Furthermore, even when the charging system is carried out, since the additional image fitted to the characteristic of the input image is added, such a problem can be avoided, so that the proper charging system can be achieved. That is, for instance, although the input image is the black/white image, since the additional image is only the color additional image, the charge amount for the color input image is mistakenly calculated. In accordance with the present invention, there is such an effect that the image processing apparatus capable of giving usabilities to the users can be provided.
