Description

  The present invention provides a data processing apparatus and control suitable for displaying a list of relationships between original image data and a plurality of image data created by processing by adding identification information corresponding to the processing to the image data. The present invention relates to a method and a program.

  In recent years, the amount of image data handled by a digital camera has increased with an increase in the capacity of a memory used in an imaging apparatus (digital camera). In this situation, the user transfers the image data captured by the digital camera and recorded in the memory to the information processing apparatus, and the information processing apparatus performs processing such as copying and processing of the image data. The amount of image data held inside increases.

  When a user pays attention to certain image data held in the information processing apparatus after a while after transferring the image data from the digital camera to the information processing apparatus, there is the following problem. That is, it is conceivable that the intention of creating the image data is forgotten and it is impossible to determine whether the image data is necessary. In addition, since a lot of image data is created as a result of processing the image data, it becomes difficult to determine which image data is the original image data, and the image data that is supposed to be unnecessary can be held without any help. There are also people.

  In view of the above, there is a demand for a technique for displaying a history of processing performed on image data in an easy-to-understand manner for the user. Various technologies have been proposed for displaying this type of image data processing history (see, for example, Patent Document 1 and Patent Document 2).

In the technique described in Patent Document 1, a history of processing performed on image data is displayed as a character string, and can be displayed even when there is a branch in processing. In the technique described in Patent Document 2, a history of processes performed until the selected image data is created can be displayed as a list of images.

  However, the above prior art has the following problems. In the technique described in Patent Document 1, the processing history when the processing for the image data is branched can be displayed. However, since the processing history is not displayed in the image list, the processing history is visually displayed. There is a problem that it cannot be grasped. In the technique described in Patent Document 2, the processing history is displayed as a list of images. However, there is a problem that it is not possible to display how the selected image data has been processed thereafter, and a problem that it is not possible to display the history of the process when there is a branch in the process.

  An object of the present invention is to make it easy to grasp how an image has been processed, to easily determine whether it is an unnecessary image, and to make it easier to organize images than in the past. An apparatus, a control method, and a program are provided.

  In order to achieve the above object, a data processing apparatus according to the present invention includes a first adding unit that adds unique identification information to image data, and image data created by processing the image data of the processing source. Second adding means for adding identification information for identifying the processing to the image data, and identification information indicating that the processing has been performed a plurality of times when the processing is performed on the image data of the processing source. Third addition means for adding to the created image data, and a history for displaying the correspondence between the processing source image data and each created image data according to the processing history and the image creation process. Display control means for performing branch display.

  According to the present invention, since the history branch display is performed in which the correspondence relationship between the processing source image data and each created image data is branched according to the processing history and the image creation process, the user can It will be easier to understand how was processed. As a result, it is easy to determine whether the stored image is an unnecessary image, and it becomes possible to organize the images more easily than in the past.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a schematic configuration of an information processing apparatus as a data processing apparatus according to the first embodiment of the present invention.

  In FIG. 1, the information processing apparatus includes a control unit 1, a storage unit 2, a display unit 3, an operation unit 4, and an interface (I / F) unit 5, and is configured as a personal computer, for example. The control unit 1 (first addition unit, second addition unit, third addition unit, display control unit) controls each unit of the information processing apparatus via the system bus 6. Moreover, the control part 1 performs the process shown to each flowchart of FIGS. 3-5 and FIGS. 8-11 based on the control program stored in the memory | storage part 2. FIG.

  The storage unit 2 (recording unit) includes a ROM, a RAM, a hard disk, and the like. The storage unit 2 includes a control program, image data to which a unique ID (identification information) for identifying a process to be performed is added, data indicating the correspondence in FIG. 2, data indicating the correspondence in FIG. Stored. The display unit 3 displays a list of images, which will be described later, on the screen 100 (see FIG. 6) based on the control of the control unit 1. The operation unit 4 includes a keyboard, a mouse, and the like, and is operated when the user selects image data or inputs data.

  The interface (I / F) unit 5 serves as an interface for reading image data from a recording medium 7 such as a memory card in which image data captured by a user using an imaging device (digital camera) is recorded. The information processing apparatus in FIG. 1 shows a general configuration example, and is not limited to the illustrated configuration, and the type and number of components are arbitrary.

  This embodiment has the following features. The control unit 1 performs history branching display in which the correspondence between the processing source image data and each created image data is branched and displayed according to the processing history and the image creation process. The display method of the history branch display includes a processing history display for displaying a history of processing performed, an image creation history display for displaying a process of creating an image, and an all-image display for displaying all the created images. . Further, in the history branch display, the control unit 1 performs display control for displaying the correspondence between the processing source image data and the image data created from the processing source image data, and the type of processing in an identifiable manner. Details will be described later.

  Next, various processes of the information processing apparatus of the present embodiment having the above configuration will be described in detail with reference to the drawings.

  First, a method for adding an ID to image data created by various processes in the information processing apparatus will be described with reference to FIG.

  FIG. 2 is a diagram illustrating a correspondence relationship between an ID added to image data and processing performed on the image data.

  In FIG. 2, the data indicating the correspondence between the ID (1, 2, 3, 4...) Added to the image data and the processing (processing, reduction, copying (copying), trimming...) Is information. It is recorded in the storage unit 2 of the processing device. A unique ID is added to the original image data before various processes are performed. The processing is processing for changing the color, brightness, etc. of the image, for example.

  When the processing is performed on the original image data IO and the image data IM is created, the image data IO with the ID shown in FIG. 2 added to the end of the ID of the image data IO is added to the image data IM. When the image data IM2 is created by further processing the image data IM, the image data IM with the ID shown in FIG. 2 added to the end of the ID is added to the image data IM2. That is, an ID (identification information) for identifying the processing is added to the image data created by processing the processing source image data.

  When the same processing is repeated for the same image data, “P” is added to the end of the ID of the image data, and the number of repeated processing is added thereafter. Thus, even when the same processing is repeated for the same image data, a unique ID can be added to the created image data. That is, when a plurality of times of processing is performed on the image data of the processing source, an ID (identification information) indicating that the plurality of times of processing has been performed is added to the created image data.

  For example, the ID of the image data IM that is copied with respect to the image data I having the ID of 0x12345678901234567890123456789010 is 0x1234567890345567890123456789012_3. Further, the ID of the image data IM2 that is copied again with respect to the image data I is 0x1234567890123456789012556789012_3P2. The ID of the image data IM3 obtained by copying the image data I2 is 0x123456789034556789012345789902_3P2_3.

  Next, referring to FIGS. 3a and 3b, the user selects a file of image data I and displays a list of image data histories created for the original image data of image data I in the information processing apparatus. While explaining.

  3A and 3B are flowcharts showing a procedure for displaying a list of image data histories created by processing original image data of selected image data.

  3A and 3B, in step S301, the control unit 1 of the information processing apparatus acquires the ID of the image data I selected by the user via the display unit 3 and the operation unit 4. In step S302, the control unit 1 acquires the ID of the original image data from the ID of the image data I acquired in step S301. That is, the ID of the image data I acquired in step S301 is checked from the left, and a character string from the beginning to the character before “_” is acquired. The acquired character string is the ID of the original image data.

  In step S303, the control unit 1 lists a character string including the character string acquired in step S302 in the ID of the image data in an ascending order in the list. In step S304, the control unit 1 displays the image with the smallest ID and the file name on the display unit 3. That is, the original image and its file name are displayed on the display unit 3.

  In step S305, the control unit 1 determines whether all images are displayed on the display unit 3. If it is determined in step S305 that all images are not displayed, in step S306, the control unit 1 acquires the ID of the next image data from the listed list. In step S307, the control unit 1 searches the ID acquired in step S306 from the right, and acquires the character string IDL on the left side and the character string IDR on the right side from where “_” is first found. In this case, IDL is the ID of the image data of the processing source (processing target), and IDR is a character string indicating the processing.

  In step S308, the control unit 1 checks whether image data whose ID is IDL exists in the listed list. If it is determined in step S308 that there is image data whose ID is IDL, in step S309, the control unit 1 performs the following process. The display position of the image on the display unit 3 is determined from the IDL, the color of the arrow for identifying the processing executed on the image data is determined from the IDR, and the image and its file name are displayed on the display unit 3. Then, the process returns to step S305.

  If it is determined in step S308 that there is no image data whose ID is IDL, the control unit 1 performs the following process in step S310. The IDL is searched from the right, and the character string IDL2 on the left side and the character string IDR2 on the right side are acquired from where “_” is first found. In step S311, the control unit 1 checks whether image data whose ID is IDL2 exists in the listed list.

  If it is determined in step S311 that there is image data whose ID is IDL2, in step S312, the control unit 1 performs the following process. The display position of the image on the display unit 3 is determined from IDL2, the color of the arrow for identifying the processing executed on the image data is determined from IDR2, and a cross mark is used to indicate that there is no image data whose ID is IDL2. Display (see FIG. 6). In this case, the control unit 1 searches for the parent image data of the image data. If the parent image data is not found, the search is continued until the parent image data is found. In step S313, the control unit 1 adds IDL2 to the list and sorts it in ascending order. Then, the process returns to step S305.

  If it is determined in step S311 that there is no image data whose ID is IDL2, in step S314, the control unit 1 sets IDL to IDL2 and returns to step S310. If image data whose ID is IDL2 exists in the list enumerated by executing step S311 again, in step S312, the number of times that the image data was not found is determined in step S312. Display the image. In step S313, all the IDs of the image data not found are added to the list and sorted in ascending order.

  If it is determined in step S305 that all images have been displayed on the display unit 3, the present process is terminated.

  In this embodiment, since the IDs are listed in ascending order, when image data created by processing one image data is displayed, the image data can be displayed for each performed processing. . This has the advantage that the processing performed on the image data can be compared.

  Next, with reference to FIGS. 4a and 4b, the user selects the image data I in the information processing apparatus and displays the history of the image data created by the processing performed on the image data I as an image list. While explaining.

  4A and 4B are flowcharts showing a procedure for displaying image data created by processing the selected image data.

  4A and 4B, in step S401, the control unit 1 of the information processing apparatus acquires the ID of the image data I selected by the user via the display unit 3 and the operation unit 4. In step S402, the control unit 1 lists image data including the character string acquired in step S401 in the image data ID in ascending order in the list. The processing after step S403 is the same as the processing after step S304 in FIG.

  Next, a procedure in which the user selects image data I in the information processing apparatus and displays what image data I has been created through as a list of images will be described with reference to FIGS. 5a and 5b. .

  5a and 5b are flowcharts showing a procedure for displaying how the selected image data is created.

  5a and 5b, in step S501, the control unit 1 of the information processing apparatus acquires the ID of the image data selected by the user via the display unit 3 and the operation unit 4. In step S502, the control unit 1 acquires the original image data ID from the image data ID acquired in step S501. That is, the ID of the image data acquired in step S501 is checked from the left, and the character string from the top to the character before “_” is acquired. The acquired character string is the ID of the original image data.

  In step S503, the control unit 1 lists an image data list including the character string acquired in step S502 in an ID in ascending order. In step S504, the control unit 1 sets the DID as the ID acquired in step S502. In step S505, the control unit 1 checks the number of “_” from the ID of the image data selected by the user and sets it to N. The value of N is the number of processes processed from the original image data before obtaining the image data selected by the user.

  In step S506, the control unit 1 sets I = 0. In step S507, the control unit 1 checks whether I = N. If it is determined in step S507 that I = N is not satisfied, in step S508, the control unit 1 checks whether image data whose ID is DID exists in the listed list.

  When it is determined that there is image data whose ID is DID in the list listed in step S508, in step S509, the control unit 1 displays the image whose ID is DID and its file name on the display unit 3, The process proceeds to step S511. If it is determined that there is no image data whose ID is DID in the list listed in step S508, the control unit 1 displays the image on the display unit 3 with a cross in step S510, and the process proceeds to step S511. .

  In step S511, the control unit 1 searches the ID of the image data selected by the user from the next character of the DID to the next “_”, and the character after the search start character before the end of the search. Get the column PR. The character string acquired here is an ID indicating the processing performed and an ID indicating the number of times that processing has been performed on the image data of the processing source.

  In step S512, the control unit 1 acquires the first character from the character string PR acquired in step S511, and displays an arrow indicating the processing performed on the image data on the display unit 3. In step S513, the control unit 1 concatenates the character string PR acquired in step S511 after the character string DID to obtain a DID. In step S514, the control unit 1 adds 1 to I and returns to step S507.

  If it is determined in step S507 that I = N, in step S515, the control unit 1 checks whether I = 0. If it is determined in step S515 that I is not 0, in step S516, the control unit 1 searches the ID of the image data selected by the user from the right, and acquires the character before “_”.

  In step S517, the control unit 1 displays an arrow indicating processing from the character acquired in step S516 on the display unit 3. In step S518, the control unit 1 displays the image and file name selected by the user on the display unit 3, and ends this process. If it is determined in step S515 that I = 0, the process of step S518 is performed, and this process ends.

  Next, a screen displayed as a list display of images on the display unit 3 of the information processing apparatus will be described with reference to FIG.

In the present embodiment, it is assumed that the image data I1 to image data I6 are created by the following procedure (Process 1 to Process 6) in the information processing apparatus.
1. The image data I1 (STI1000.jpg) is processed to create image data I2 (STI1001.jpg).
2. Another processing is performed on the image data I1, and image data I3 (STI1003.jpg) is created.
3. The image data I1 is reduced and image data I4 (STI1005.jpg) is created.
4). Copying is performed on the image data I2, and image data I5 (STI1010.jpg) is created.
5). The image data I3 is processed to generate image data I6 (STI1100.jpg).
6). The image data I3 is deleted.

  In the present embodiment, it is assumed that processing 1 to processing 5 do not change the processing source image data.

  A unique ID is added to the image data I1. As shown in FIG. 2, the ID of the image data I2 to the image data I6 created by the above procedure is suffixed with an ID indicating the processing performed. It shall be added to. In the following, it is assumed that all the image data I1 to image data I6 are displayed, and the image list display of the image data I1 to image data I6 is displayed according to the procedure described above (see FIG. 3). It is assumed that the user has selected the image data I2.

  FIG. 6 is a diagram showing a list of images displayed on the display unit 3 of the information processing apparatus.

  In FIG. 6, a screen 100 is a screen displayed on the display unit 3 under the control of the control unit 1 when the user selects image data. That is, the control unit 1 retrieves image data from the storage unit 2 based on the ID of the image data selected by the user, lists the processing source image data and the image data created by the processing, and thumbnails of the images. A list of (reduced images) is displayed on the screen 100. When a list of images is displayed, not only thumbnails of images but also file names of images are displayed.

  The correspondence between the image data of the processing source and the image data created by the processing is displayed by arrows 103 to 107 in the example of FIG. The directions of the arrows 103 to 107 indicate the directions from the processing source image data to the image data created by the processing. Further, the arrows 103 to 107 are displayed in different colors according to the processing performed on the image data. In the example of FIG. 6, an arrow 103, an arrow 104, and an arrow 107 indicate processing (for example, change in image color and brightness), an arrow 105 indicates reduction processing, and an arrow 106 indicates copying processing.

  When the user selects an image file via the display unit 3 and the operation unit 4, a thumbnail is displayed as a selected state surrounded by a square of a predetermined display color (for example, red), and the path of the selected image file is an edit box. 101. The radio button 102 (selection means) is a button for selecting an image list display method (history branch display display method).

  In this embodiment, the image list display method includes “display all images” (display all images), “display added processing history” (display processing history), and “display image creation history”. (Image creation history display). “Display all images” is a display method for displaying all created images (displaying all images). “Display added processing history” is a display method for displaying a history of processing performed on image data. “Display image creation history” is a display method for displaying a process in which an image is created in accordance with processing.

  When “display all images” is selected, all images created by the processing performed on the original image in the procedure shown in FIG. 3 are displayed. When “Display added processing history” is selected, the history of images created by the processing performed on the image selected in the procedure shown in FIG. 4 is displayed. When “Display image creation history” is selected, a process of creating an image selected from the original image by the procedure shown in FIG. 5 is displayed.

  In the example of FIG. 6, since “display all images” is selected by the radio button 102 (black circle), the history of creating the image data I2 and all the images generated by processing the image data I2 are displayed. The In addition, an image having the same image data as the selected image data (copy image) has a display color (for example, red) different from the normal display color (for example, red) to indicate that the image data is the same as the selected image data. Displayed with a blue square. That is, the image is displayed in a display form indicating that the image has the same image data as the selected image data. In the example of FIG. 6, images STI1001. Since jpg is selected, it is displayed surrounded by a normal display color. In addition, the image STI1010. jpg is the image STI1001. Since the image has the same image data as jpg, it is displayed in a color different from the normal display color.

  When the image data of the processing source is deleted after processing the image data of the processing source to create the image data, the following display is performed. In order to indicate that the deleted image data once existed as the processing source image data, a cross mark indicating that the processing source image data has been deleted is displayed in the square. That is, the image data is displayed in a display form indicating that the image data has been deleted. In the example of FIG. 6, the thumbnail of the image data I3 is displayed as a cross.

  In this embodiment, radio buttons are used as means for selecting an image list display method. However, a check box or the like may be used. Further, although the arrows are distinguished by color in order to distinguish the processing performed on the image data, the processing performed on the image data may be displayed with a tool tip.

  As described above, according to the present embodiment, the history branch display that displays the correspondence between the processing source image data and each created image data by branching according to the processing history and the image creation process. I do. That is, even when there is a branch in the processing for image data (processing, reduction, copying, etc.), the images created by the processing for the image data and the processing history can be displayed as a list of images. This makes it easier for users to understand how images have been processed, and makes it easier to determine whether stored images are unnecessary images, making it easier to organize images than before. Is possible.

[Second Embodiment]
The second embodiment of the present invention differs from the first embodiment in the following points. Since the other elements of the present embodiment are the same as the corresponding ones of the first embodiment (FIG. 1), description thereof is omitted.

  Next, an example of creating image data by performing processing on the image data of the processing source in the information processing apparatus of the present embodiment and adding an ID to the created image data will be described with reference to FIG.

  FIG. 7 is a diagram showing the processing performed on the image data and the number of each processing performed in the past held in the image data.

  In FIG. 7, data indicating a correspondence relationship between processing (copying (copying), reduction, processing, trimming) performed on image data and the number of times (5, 3, 2, 9) is the storage unit 2 of the information processing apparatus. (Recording means).

  In the present embodiment, the number of each processing performed in the past on the image data is recorded in the storage unit 2 as metadata inside the image data. That is, the number of processes performed on the processing source image data is recorded for each process. The ID of the image data I is assumed to be 0x12345678890125676789012345689012. Hereinafter, an example in which image data I2 is created by copying image data I will be described.

  The control unit 1 of the information processing apparatus refers to the metadata in the image data I and checks how many times the image data I has been copied in the past. The control unit 1 confirms that the number of times the image data I has been copied in the past from the data recorded in the storage unit 2 (FIG. 7) is five, and sets the number of copies to the image data I to six (past The number of times of copying is updated to 5 + the number of times of copying this time 1).

  Next, since the ID of the image data I2 created by copying the image data I is the sixth copy of the image data I, it becomes 0x123456789034556789012345789902_3P6. The control unit 1 records the ID as metadata inside the image data I2.

  As described above, according to the present embodiment, even when the same type of processing is performed a plurality of times on the original image data, a unique ID is assigned to the image data created by the processing. Can be added. This makes it easier for users to understand how images have been processed, and makes it easier to determine whether stored images are unnecessary images, making it easier to organize images than before. Is possible.

[Third Embodiment]
The third embodiment of the present invention differs from the first embodiment in the following points. Since the other elements of the present embodiment are the same as the corresponding ones of the first embodiment (FIG. 1), description thereof is omitted.

  In the first embodiment, the case where the ID of the image data created by processing from the original image data is added with the ID indicating the processing performed at the end of the ID of the original image data has been described.

  In contrast, in the present embodiment, the following example will be described. That is, when image data is created by processing from the original image data, the ID of the image data created in the first embodiment is used as processing information (metadata) inside the image data created by the processing. By recording it, a list of images is displayed. In the case of original image data, the processing information remains initialized with 0 to indicate that there is no processing source image data.

  Next, processing when the image data I is created by performing processing on the image data IO in the information processing apparatus of the present embodiment will be described with reference to FIG.

  FIG. 8 is a flowchart showing a procedure for adding ID to image data and recording processing information.

  In FIG. 8, in step S701, the control unit 1 of the information processing apparatus refers to the processing information recorded as metadata in the image data IO and sets the acquired value as a character string Info. In step S702, the control unit 1 determines whether or not the value acquired in step S701 is zero. If it is determined that the acquired value is 0, the control unit 1 indicates that the processing source image data is original image data, and the process proceeds to step S703. If it is determined that the acquired value is not 0, the control unit 1 indicates that the processing source image data has been created by processing another image data, and the process proceeds to step S704.

  In step S703, the control unit 1 acquires the ID of the image data IO and sets it as a character string Info. In step S704, the control unit 1 concatenates an ID indicating processing at the end of the character string Info, and records it as processing information inside the image data I.

  Next, with reference to FIGS. 9a and 9b, the user selects a file of image data I and displays a list of image data histories created for the original image data of image data I in the information processing apparatus. While explaining.

  9a and 9b are flowcharts showing a procedure for displaying a list of image data histories created by processing original image data of selected image data.

  9A and 9B, in step S801, the control unit 1 of the information processing apparatus refers to the processing information of the image data I selected by the user via the display unit 3 and the operation unit 4, and sets the acquired value. It is assumed to be a character string Info. In step S802, the control unit 1 determines whether Info acquired in step S801 is zero. If it is determined that Info is 0, the process proceeds to step S803. If it is determined that Info is not 0, the process proceeds to step S804.

  In step S803, the control unit 1 sets the ID of the image data I as a character string Info. In step S804, the control unit 1 acquires the ID of the original image data from the character string Info. That is, the character string Info is checked from the left, and the character string from the beginning to the character before “_” is acquired. The acquired character string is the ID of the original image data.

  In step S805, the control unit 1 lists, in ascending order, character strings that include the character string acquired in step S804 in the image data ID or processing information. It is the original image data that has the acquired character string as the ID of the image data. The acquired character string as processing information is image data created by processing from the original image data. In step S806, the control unit 1 displays the image with the smallest character string and its file name on the display unit 3. That is, the original image and its file name are displayed on the display unit 3.

  In step S807, the control unit 1 determines whether all images are displayed on the display unit 3. If it is determined in step S807 that not all images are displayed on the display unit 3, the control unit 1 acquires the next character string from the listed list in step S808. In step S809, the control unit 1 searches the character string acquired in step S806 from the right, and acquires the left character string IDL and the right character string IDR from where “_” is first found. IDL is the ID of the image data of the processing source, and IDR is a character string indicating the processing.

  In step S810, the control unit 1 checks whether there is image data whose processing information is IDL in the listed list. If it is determined in step S810 that there is image data whose processing information is IDL, in step S811, the control unit 1 performs the following process. The display position of the image on the display unit 3 is determined from the IDL, the color of the arrow for identifying the process executed from the IDR is determined, and the image and its file name are displayed on the display unit 3. Then, the process returns to step S807.

  If it is determined in step S810 that there is no image data whose processing information is IDL, in step S812, the control unit 1 searches the IDL from the right, and the character string IDL2 on the left side from where “_” is first found. And the character string IDR2 on the right side are acquired. In step S813, the control unit 1 checks whether there is image data whose character string is IDL2 in the listed list.

  If it is determined in step S813 that there is image data whose character string is IDL2, the control unit 1 performs the following process in step S814. The display position of the image on the display unit 3 is determined from IDL2, the color of the arrow for identifying the process executed from IDR2 is determined, and a cross is displayed to indicate that there is no image data whose character string is IDL2. . In this case, the control unit 1 searches for the parent image data of the image data. If the parent image data is not found, the search is continued until the parent image data is found. In step S815, the control unit 1 adds IDL2 to the list and sorts the list in ascending order. Then, the process returns to step S807.

  If it is determined in step S813 that there is no image data whose character string is IDL2, in step S816, the control unit 1 sets IDL to IDL2, and returns to step S812. If there is an image whose image data ID is IDL2 in the list enumerated by executing the process in step S813 again, in step S814, in step S814, as many times as the number of times image data has not been found. Display the image at. In step S815, the control unit 1 adds all the processing information not found to the list and sorts the information in ascending order.

  If it is determined in step S807 that all the images have been displayed on the display unit 3, this process ends.

  In the present embodiment, in order to enumerate the character strings represented by the ID of the image data and the processing information in ascending order, the processing performed when one image data is processed and the created image is displayed. Each image can be displayed. This has the advantage that the processing performed on the image data can be compared.

  Next, with reference to FIGS. 10a and 10b, the user selects the image data I in the information processing apparatus and displays the history of the images created by the processing performed on the image data I as an image list. While explaining.

  10a and 10b are flowcharts showing a procedure for displaying image data created by processing the selected image data.

  10A and 10B, in step S901, the control unit 1 of the information processing apparatus refers to the processing information of the image data I selected by the user via the display unit 3 and the operation unit 4, and sets the acquired value. It is assumed to be a character string Info. In step S902, the control unit 1 determines whether Info acquired in step S901 is 0. If Info is 0, the process proceeds to step S903. If Info is not 0, the process proceeds to step S904.

  In step S903, the control unit 1 sets the ID of the image data I to Info. In step S904, the control unit 1 lists image data including the character string Info in the processing information in an ascending order in the list. Since the process after step S905 is the same procedure as the process after step S806 of FIG. 9, description is abbreviate | omitted.

  Next, a procedure in which the user selects the image data I in the information processing apparatus and displays what image data I has been created through as an image list will be described with reference to FIGS. 11a and 11b. .

  11a and 11b are flowcharts showing a procedure for displaying how the selected image data is created.

  11A and 11B, in step S1001, the control unit 1 of the information processing apparatus refers to the processing information of the image data I selected by the user via the display unit 3 and the operation unit 4, and obtains the acquired value. It is assumed to be a character string Info. In step S1002, the control unit 1 determines whether Info acquired in step S1001 is 0. If it is determined that Info is 0, the process proceeds to step S1003. If it is determined that Info is not 0, the process proceeds to step S1004.

  In step S1003, the control unit 1 sets the ID of the image data I as a character string Info. In step S1004, the control unit 1 acquires the ID of the original image data from the character string Info. That is, the character string Info is checked from the left, and the character string from the beginning to the character before “_” is acquired. The acquired character string is the ID of the original image data.

  In step S1005, the control unit 1 lists a list of character strings including the acquired character strings in the image data ID or processing information in ascending order. In step S1006, the control unit 1 sets the DID as the character string acquired in step S1004. In step S1007, the control unit 1 examines the number of “_” from the ID of the image data selected by the user or the processing information and sets it to N. The value of N is the number of processes processed from the original image data before obtaining the image data selected by the user.

  In step S1008, the control unit 1 sets I = 0. In step S1009, the control unit 1 checks whether I = N. If it is determined in step S1009 that I = N is not satisfied, in step S1010, the control unit 1 checks whether the DID exists in the enumerated list.

  If it is determined in step S1010 that the DID is present in the enumerated list, in step S1011, the control unit 1 displays an image whose ID or processing information is DID and the file name thereof on the display unit 3, and proceeds to step S1013. To do. If it is determined in step S1010 that the DID does not exist in the listed list, in step S1012, the control unit 1 displays the image with a cross mark, and the process proceeds to step S1013.

  In step S1013, the control unit 1 searches for the ID or processing information of the image data selected by the user from the next character of the DID to the next “_”, and ends the search from the character next to the search start character. Get the previous character string PR. The character string acquired here is an ID indicating the processing performed and an ID indicating the number of times that processing has been performed on the image data of the processing source.

  In step S1014, the control unit 1 acquires the first character from the character string PR acquired in step S1013, and displays an arrow indicating the performed process on the display unit 3. In step S1015, the control unit 1 displays an arrow indicating processing from the character acquired in step S1014 on the display unit 3. In step S1016, the control unit 1 concatenates the character string PR acquired in step S1014 after the character string DID to obtain a DID. In step S1017, the control unit 1 adds 1 to I and returns to step S1009.

  If it is determined in step S1009 that I = N, in step S1018, the control unit 1 checks whether I = 0. If it is determined in step S1018 that I = 0 is not satisfied, in step S1019, the control unit 1 retrieves the ID or processing information of the image data selected by the user from the right, and acquires the character before “_”. In step S1020, the control unit 1 displays an arrow indicating processing from the characters acquired in step S1019 on the display unit 3. In step S1021, the control unit 1 displays the image and file name selected by the user on the display unit 3, and ends this process.

  If it is determined in step S1018 that I = 0, the control unit 1 performs the process of step S1021 and ends this process.
