Description

  The present invention relates to an image data processing apparatus that performs processing related to thumbnail image data for displaying a reduced image of a predetermined image, a method thereof, and a program thereof.

  In recent years, in an image display device, thumbnail image data for displaying a reduced image (hereinafter referred to as a thumbnail image) obtained by reducing a predetermined image (hereinafter referred to as a main image) is a main image for displaying the main image. Since the amount of data is smaller than that of data, it is often used as substitute image data for main image data as a method for improving the response of image display. There is an area in which thumbnail image data can be recorded in the main image file compliant with the Exif (Exchangeable Image File Format) standard (a file format standard for digital cameras). In order to display the thumbnail image of the thumbnail image data recorded here, the following two methods can be considered.

  The first method is a method of always extracting and displaying thumbnail image data from main image data. In this first method, thumbnail image data is extracted from the main image data every time, so there is no possibility that the relationship between the main image and the thumbnail image is impaired. For this reason, it is always guaranteed that the main image and the thumbnail image are the same object.

  The second method saves a thumbnail file including thumbnail image data extracted from the main image data separately when the main image file is stored in advance, and exists with the same file name as the main image file when displaying the thumbnail image. In this method, thumbnail image data of a thumbnail file to be read is directly read and displayed. Since the second method does not extract thumbnail image data for each display, the second method has a feature that the display start response is faster than the first method.

  In addition, a configuration is known in which main image data and thumbnail image data are associated with each other using a method different from the first method and the second method described above (see, for example, Patent Document 1). In the apparatus disclosed in Patent Document 1, an image to be compressed is compressed (recompressed) by an image compression unit from a digital camera or the like. Then, the storage location information adding unit adds a URL (Uniform Resource Locator) of the compression target image to the header portion when forming the code data for the compressed image compressed by the image compressing unit.

JP 2004-274710 A (pages 14 to 16)

  By the way, in the second method described above and the method described in Patent Document 1, a main image and a compression target image (hereinafter, the main image and the compression target image are collectively referred to as a main image as appropriate) and a thumbnail. Images and compressed images (hereinafter, thumbnail images and compressed images are collectively referred to as thumbnail images as appropriate) are associated only with a file name or URL. For this reason, when a thumbnail file once saved, for example, is replaced with another thumbnail file with the same file name, a thumbnail image different from the main image may be displayed. Further, when the compressed image is replaced with another compressed image, a compressed image different from the compression target image may be displayed. Therefore, as a method for solving such problems, a method is conceivable in which a thumbnail image is extracted again from the main image, and the main image and the thumbnail image are made to correspond by the above-described second method or the method of Patent Document 1.

  However, in the method as described above, when one thumbnail file or compressed image is replaced among a plurality of thumbnail files or compressed images, it is specified which thumbnail file is replaced among the plurality of thumbnail files. In order to make all main images and thumbnail images correspond to each other appropriately, the second method and the method of Patent Document 1 are applied to the thumbnail images that have not been replaced in addition to the replaced thumbnail images. It is necessary to carry out the processing corresponding to. For this reason, the problem that processing time for making all the main images and thumbnail images appropriately correspond to each other may be long.

  In view of such circumstances, an object of the present invention is to provide an image data processing apparatus, a method thereof, and a program thereof that can quickly perform processing for appropriately matching image data and reduced image data. is there.

  Then, when displaying the main image selection screen 421, the selection screen display processing unit 458 controls the corresponding main image search unit 457 so that the main image that matches the content of the corresponding main image unique information 911B of the predetermined thumbnail file 910 is displayed. The file 810 is searched. Further, when it is recognized that the matching main image presence signal is input from the corresponding main image search means 457, it is recognized that the main image file 810 corresponding to the thumbnail file 910 exists. Then, based on the thumbnail file 910 acquired by the corresponding main image search unit 457, the thumbnail image 425 is displayed in the thumbnail image area 422, and the file name information 427 is displayed in the file name area 423, respectively.

  When the selection screen display processing unit 458 recognizes that the matching main image non-existence signal is input from the corresponding main image search unit 457, the thumbnail file 910 has been illegally replaced. It recognizes that the image file 810 does not exist. Then, based on the thumbnail file 910 acquired by the corresponding main image search unit 457, the file name information 427 is displayed in the file name area 423. Further, a replacement warning mark 426 is displayed in the thumbnail image area 422. Note that only the replacement warning mark 426 may be displayed without displaying the file name information 427.

  The display control unit 459 causes the display unit 420 to display a predetermined main image based on the main image file 810. Specifically, when the display control unit 459 recognizes an input operation for selecting any one of the thumbnail image areas 422 on the main image selection screen 421, whether or not the thumbnail image 425 is displayed in the thumbnail image area 422. Determine whether. If it is determined that the thumbnail image 425 is displayed, the display of the main image selection screen 421 is terminated, and the thumbnail image is based on the main image data 813 of the main image file 810 searched by the corresponding main image search unit 457. 425 main images are displayed.

[Operation of image data editing system]
Next, main image display processing and thumbnail file restoration processing will be described as operations of the image data editing system 100 with reference to the drawings. FIG. 6 is a flowchart showing main image display processing and thumbnail file restoration processing. FIG. 7 is a flowchart showing main image selection display processing. FIG. 8 is a flowchart showing the thumbnail file saving process.

  First, in the image data editing apparatus 400 of the image data editing system 100, the processing unit 450 appropriately stores a main image file 810 and a thumbnail file 910 relating to a predetermined main image in the storage unit 430 and the memory 440, respectively. Then, the processing unit 450 requests the selection screen display processing unit 458 whether or not a setting input for selecting and displaying the main image has been performed, as shown in FIG. It is determined whether or not (step S101). If it is determined in step S101 that a main image selection display request has been made, a main image selection display process is performed (step S102), and the process ends.

  On the other hand, if the processing unit 450 determines in step S101 that a main image selection display request has not been made, whether or not a setting input for restoring the thumbnail file 910 has been performed by the thumbnail storage processing unit 456, That is, it is determined whether a repair request for the thumbnail file 910 has been made (step S103). If it is determined that no repair request has been made, the process ends. In step S103, if the thumbnail storage processing unit 456 determines that a repair request has been made, the thumbnail storage processing unit 456 controls the corresponding thumbnail search unit 454 to check whether a thumbnail file 910 having the same file name as the predetermined main image file 810 exists. It is determined whether or not (step S104).

  In step S104, when the corresponding thumbnail search unit 454 determines that there is no thumbnail file 910 having the same file name, the corresponding thumbnail search unit 454 outputs an identical file name nonexistence signal to the thumbnail storage processing unit 456. Then, when the same file name nonexistence signal is input, the thumbnail saving processing unit 456 recognizes that the thumbnail file 910 corresponding to the main image file 810 has been deleted, and selects the thumbnail file 910 corresponding to the main image file 810. A thumbnail file saving process to be generated and saved is performed (step S105). Thereafter, the thumbnail storage processing unit 456 determines whether or not the thumbnail file 910 having the same file name has been searched for all the main image files 810 stored in the storage unit 430 (step S106). If it is determined in step S106 that all main image files 810 have been searched, the process ends. On the other hand, if it is determined in step S106 that all main image files 810 have not been searched, the process returns to step S104.

  In step S104, when the corresponding thumbnail search unit 454 determines that there is a thumbnail file 910 having the same file name, the corresponding thumbnail search unit 454 outputs the same file name presence signal to the unique content match determination unit 455. Then, when the same file name presence signal is input, the unique content match determination unit 455 acquires a thumbnail file 910 having the same file name as the main image file 810. Thereafter, it is determined whether or not the content of the corresponding main image unique information 911B of the thumbnail file 910 matches the main image file 810 (step S107).

  In this step S107, when the unique content matching determination unit 455 determines that they match, it outputs a matching thumbnail signal to the thumbnail storage processing unit 456. When the thumbnail storage processing unit 456 recognizes that the matching thumbnail signal has been input, the thumbnail storage processing unit 456 recognizes that the thumbnail file 910 corresponding to the predetermined main image file 810 exists, and performs the process of step S106. On the other hand, if the unique content match determination unit 455 determines in step S107 that they do not match, it outputs a mismatched thumbnail signal. When the thumbnail storage processing unit 456 recognizes that the mismatched thumbnail signal has been input, it recognizes that the thumbnail file 910 corresponding to the predetermined main image file 810 has been illegally replaced, and performs the process of step S105. .

  On the other hand, in the main image selection display process, the selection screen display processing means 458 displays the main image selection screen 421. Specifically, as shown in FIG. 7, the selection screen display processing unit 458 controls the corresponding main image search unit 457, and the main image whose contents match the corresponding main image unique information 911B of the predetermined thumbnail file 910. It is determined whether or not the file 810 exists (step S201). In step S201, the corresponding main image search unit 457 outputs a matching main image presence signal to the selection screen display processing unit 458 when determining that there is a main image file 810 whose contents match. When the matching main image presence signal is input, the selection screen display processing unit 458 displays the thumbnail image 425 and the file name information 427 based on the thumbnail file 910 (step S202). On the other hand, if the corresponding main image search unit 457 determines in step S201 that there is no main image file 810 having the same content, it outputs a matching main image nonexistence signal. When the matching main image non-existence signal is input, the selection screen display processing means 458 notifies that the replacement warning mark 426 and the file name information 427 are displayed, that is, that the thumbnail file 910 has been illegally replaced. The process to perform is implemented (step S203).

  Thereafter, when the selection screen display processing means 458 performs the processing of step S202 or step S203, the selection screen display processing means 458 checks the main image file 810 having the same content for all the thumbnail files 910 to be displayed, that is, the four thumbnail files 910. It is determined whether or not (step S204). If it is determined in step S204 that all the thumbnail files 910 have not been checked, the process returns to step S201. On the other hand, if it is determined in step S204 that all the thumbnail files 910 have been examined, the display control unit 459 appropriately recognizes the selection of the predetermined thumbnail image area 422 on the main image selection screen 421, and stores the thumbnail image area 422 in the thumbnail image area 422. The corresponding main image is displayed (step S205), and the process ends.

  In the thumbnail file storage process, the thumbnail storage processing unit 456 controls the thumbnail acquisition unit 452 as shown in FIG. 8, and the thumbnail from the main image file 810 corresponding to the thumbnail file 910 that has been deleted or replaced illegally. Image data 812 is extracted (step S301) and acquired as extracted thumbnail image data 912. Further, if it has been deleted, the thumbnail header information generation means 453 is controlled to generate thumbnail file name information 911A. Thereafter, the thumbnail storage processing unit 456 generates corresponding main image unique information 911B of the main image file 810 (step S302). Then, the thumbnail storage processing unit 456 generates and stores the thumbnail file 910 as appropriate (step S303), and ends the processing. If the thumbnail file 910 has been deleted, a new thumbnail file 910 is generated and saved. If the thumbnail file 910 has been replaced, the extracted thumbnail image data 912 and the corresponding main image unique information 911B are overwritten and stored on the replaced thumbnail file 910.

[Effects of image data editing system]
As described above, in the above-described embodiment, the image data editing apparatus 400 of the image data editing system 100 receives the file name and “jpeg” from the imaging apparatus 200 or the like by the main image storage processing unit 451 of the processing unit 450. A main image file 810 having main image file name information 811A in which the name of the main image file 810 expressed by an extension is recorded and main image data 813 is acquired and stored in the storage unit 430. In addition, the processing unit 450 acquires the extracted thumbnail image data 912 for displaying the thumbnail image 425 obtained by reducing the main image of the main image data 813 in the thumbnail acquisition unit 452. Further, the thumbnail header information generating means 453 records the name of the thumbnail file 910 represented by the same file name as the file name recorded in the main image file name information 811A and the extension “dhm”. Information 911A and corresponding main image unique information 911B unique to main image data 813 are generated. Then, the thumbnail storage processing unit 456 generates a thumbnail file 910 having thumbnail file name information 911A, corresponding main image unique information 911B, and extracted thumbnail image data 912, and stores the thumbnail file 910 in the memory 440.

  Therefore, for example, when the thumbnail file 910 is illegally replaced, it can be recognized that the thumbnail file 910 has been replaced by the following processing. That is, a thumbnail file 910 having the same file name as the main image file 810 is searched based on the main image file name information 811A and the thumbnail file name information 911A. Further, it is determined whether or not the content of the corresponding main image unique information 911 B of the searched thumbnail file 910 matches the main image file 810. When it is determined that they do not match, it is recognized that the thumbnail file 910 has been replaced, and when it is determined that they match, it can be recognized that they have not been replaced. Therefore, the replaced thumbnail file 910 can be specified by referring to the corresponding main image unique information 911B, and all the main image files 810 and thumbnail files 910 can be stored only by performing the repair process on only the specified thumbnail file 910.

Therefore, as compared with the conventional configuration, it is possible to shorten the processing time for making all the main image files 810 and thumbnail files 910 appropriately correspond to each other.

  The main image storage processing unit 451 acquires a main image file 810 that conforms to the Exif standard. Then, the thumbnail acquisition unit 452 extracts the thumbnail image data 812 previously incorporated in the main image file 810 and acquires it as extracted thumbnail image data 912. For this reason, compared with the structure which produces | generates and acquires the extraction thumbnail image data 912 based on the main image data 813 of the main image file 810, the process which acquires the extraction thumbnail image data 912 can be expedited.

  Further, the processing unit 450 searches for a corresponding thumbnail search unit 454 for searching for a thumbnail file 910 having the same file name as the main image file 810, and corresponding main image unique information 911B of the thumbnail file 910 searched by the corresponding thumbnail search unit 454. Specific content matching determination means 455 for determining whether or not the content of the file matches the main image file 810. If the unique content match determination unit 455 determines that the thumbnails do not match, the thumbnail storage processing unit 456 recognizes that the thumbnail file 910 has been replaced, and performs a repair process. For this reason, the image data editing apparatus 400 quickly performs processing for making the main image file 810 and the thumbnail file 910 appropriately correspond to each other by the recognition processing and restoration processing of the replaced thumbnail file 910 as described above. Can be. Therefore, the convenience of the image data editing device 400 can be improved.
