Description

  The present invention relates to a technique for managing images, and more particularly to a technique for managing images in units of groups.

  Album software that manages a large amount of images collected by shooting with a digital camera (hereinafter simply referred to as “camera”) according to events such as shooting date, shooting location, athletic meet, travel, etc. There is something. Previously, album software was used in a form that is executed on a PC installed in a user's house, etc., so the functions provided by the album software, such as creating an album, adding an image to the album, Functions such as deletion, replacement of images with other albums, and browsing of albums could only be performed at the user's home. On the other hand, cameras equipped with an album function have been put on the market in recent years in order to meet the demands of users who want to view an album on the spot where the image was taken or at a travel destination where the PC is not on the spot. Yes.

A method of managing image data in a camera equipped with an album function will be described with reference to FIG.
FIG. 22 shows a management structure of image data files in a recording medium such as a memory card for storing image data in the camera. (A) is a management example in which image data files are duplicated, and (b). Shows an example of management by an image list file.

In the folder structure shown in (a), the image root folder DCIM and the album root folder ALBUM are arranged immediately below the root directory.
The image root folder is a root folder for storing image data files, and a folder 100 OLYMP is stored immediately below the folder as an image storage folder. In (a), this 100OLYMP folder stores an image data file for an image taken by a camera. That is, in FIG. JPG, 002. JPG, 003. Image data files such as JPG,... Are stored in the 100 OLYMP folder.

  On the other hand, the album root folder is a root folder for storing image data files included in the album, and album folders such as ALBUM1, ALBUM2,... Are stored in the folder. In (a), an XXX. JPG, 003. JPG, YYY. It is shown that image data files such as JPG,... Are stored. Due to this folder structure, images represented by these image data files belong to the album “ALBUM1” (included). It is expressed.

  By the way, in this (a), the image data file 003. JPG is stored in both the image root folder and the album root folder. That is, since there are two image data files having the same data content on this recording medium, the recording area is wasted. In the camera, such a wasteful consumption of the recording area leads to a decrease in the number of shootable images, which is not preferable. Moreover, the consumption of the recording area is further increased when the same image data file belongs to a plurality of albums.

On the other hand, in the folder structure shown in (b), the image root folder DCIM and the album list file ALBUM. PVM is stored directly under the root folder.
The image root folder in (b) is also the root folder for the image data file, as in (a), and a folder 100 OLYMP is stored immediately below it as an image storage folder. However, in (b), the 100 OLYMP folder stores an image data file for an image photographed by the camera, and also stores an image data file included in the album. In the figure, 001. JPG, 002. JPG, 003. JPG, ..., XXX. JPG, YYY. Image data files such as JPG,... Are stored in the 100 OLYMP folder.

  The album list file is a relationship information file indicating the relationship between the image data file stored in the image root folder and the album to which the image data file belongs (including the image data file). As shown in (b), this image list file has a data structure in which the file names of image data files belonging to each album are arranged for each album, and the file name for each album. Dependent relationship between the image data file and the album is shown by the arrangement of. The ALBUM. According to the PVM data example, for example, the image data file belonging to the album “ALBUM1” is XXX. JPG, 003. JPG, YYY. JPG,..., Etc., and the relationship between the image data file and the album is shown as in FIG. In addition, ALBUM. In the PVM data example, information (100OLYMP) indicating the folder in which the image data file is stored is omitted.

  By adopting a technique for representing the dependency between the image data file and the album using the image list file as shown in (b), a plurality of the same image data files as shown in (a) are stored in the recording medium. Since the unnecessary consumption of the recording area is eliminated, it is possible to efficiently use the recording medium of the camera with severe restrictions on the recording capacity.

A method for managing albums using image list files is also proposed in the MPV (Music Photo Video) standard developed by OSTA (Optical Storage Technology Association), which is an optical storage standardization organization.
As another background art, in Patent Document 1, in an image filing apparatus that performs image filing, a blank image is deleted by an operator from a document image stored in an MO medium. A technique of automatically selecting and deleting from the MO medium in response to an instruction is disclosed.
JP-A-9-73530 (Summary, claim 1, paragraphs [0007]-[0008], [0014]-[0022], FIGS. 1 and 2)

  As described above, the method for expressing the dependency relationship between the image data file and the album using the image list file as shown in FIG. 22B duplicates the image data file as shown in FIG. As a result, the recording area of the recording medium is saved as compared with the method of expressing the dependency, but there is a problem. One of them is deletion of image data files.

  If the management structure of the image data file shown in (a) is adopted, for example, when an instruction to delete the image from the album is received from the user, the image data file for the image related to the deletion instruction is deleted. All you have to do is delete it from the folder for the album you want to instruct.

  However, when the management structure of the image data file shown in (b) is adopted, the image related to the deletion instruction from the user is included not only in the album related to the deletion instruction but also included in other albums. Therefore, if the image data file for the image related to the deletion instruction is deleted from the image storage folder, the image cannot be displayed when browsing the other album.

  In addition, as described above, in the management structure shown in (b), an image data file for an image photographed by the camera is also stored in the image storage folder, but the photographed image is registered after such a photographed image is registered in the album. If the image data file for the photographed image is simply deleted from the image storage folder when an instruction to delete the photographed image is received from the user, the photographed image is displayed when browsing the album in which the photographed image is registered. It becomes impossible.

  Furthermore, after registering a photographed image in an album, if an instruction to delete the photographed image from the album is received from the user, the image data file for the photographed image is simply deleted from the image storage folder. In this case, the image data file for the image that should have been taken with the camera will be lost without receiving an instruction to delete the taken image from the user.

  The present invention has been made in view of the above-described problems, and a problem to be solved is to appropriately delete an image when the same image belongs to a plurality of groups. This is to maintain the effect of suppressing the consumption of the recording amount of the recording unit.

  An image management apparatus according to one aspect of the present invention includes a recording unit in which a plurality of image data files are stored, and a dependency relationship between the image data file recorded in the recording unit and a group to which the image data file belongs. And when there is an instruction to delete a predetermined image data file subordinate to a predetermined group, a specific information in the dependency information storage unit is stored. Dependency cancellation means for changing the dependency relationship information related to the predetermined image data file described in the dependency relationship information to cancel the dependency relationship indicated in the specific dependency relationship information, and the predetermined image data When the dependency relationship between the file and any group is resolved by the dependency relationship resolving means, the predetermined image data from the recording unit A data file deletion means for deleting Airu and is characterized by comprising a.

  According to this configuration, even if an instruction to delete a predetermined image data file from a predetermined group is received, any of the dependency relationship information other than the specific dependency relationship information stored in the dependency relationship information storage unit is stored. Since the image data file showing the dependency relationship with other groups is not deleted from the recording unit, the above-described problem caused by the loss of such an image data file does not occur. Accordingly, since there is no problem in the dependency relationship of other groups, the same image is distributed to a plurality of groups while maintaining the effect of suppressing the recording amount consumption of the recording unit by the group management using the dependency relationship information. When the images belong to each other, it is possible to appropriately delete the image.

In the image management apparatus according to the present invention described above, the image management apparatus may be a camera, for example.
At this time, the predetermined group described above is composed of image data files recorded in a recording unit provided in the camera by shooting with the camera, and the deletion instruction described above is obtained by shooting with the camera. The image data file that has been stored may be instructed to be deleted from the recording unit.

According to this configuration, the same image overlaps with a group other than the group of images captured by the camera while maintaining the effect of suppressing the recording amount consumption of the recording unit by managing the captured image performed using the dependency relationship information. Can be appropriately deleted.
In the above-described image management apparatus according to the present invention, the above-described group constitutes an album in which images represented by image data files belonging to the group are combined, and the above-described deletion instruction is designated in the album. The image data file for the images included in the album may be instructed to be deleted from the predetermined album.

According to this configuration, while maintaining the effect of suppressing the recording amount consumption of the recording unit by managing the album using the dependency relationship information, the same image in the case where the same image belongs to a plurality of albums overlaps. Deletion can be performed appropriately.
In addition, an image management method according to another aspect of the present invention includes a plurality of image data files recorded in a recording unit when an instruction to delete a predetermined image data file subordinate to a predetermined group is issued. Of the dependency information indicating the dependency relationship with the group to which each of the image data file belongs, the information related to the predetermined image data file is changed to eliminate the dependency relationship indicated in the specific dependency information. The predetermined image data file is deleted from the recording unit when the dependency relationship between the predetermined image data file and any group is resolved.

  This method also solves the above-described problems of the present invention as a result of the same operations and effects as the image management apparatus according to the present invention.

  As described above, according to the present invention, the image is appropriately deleted when the same image belongs to a plurality of groups while maintaining the effect of suppressing the consumption of the recording amount of the recording unit. However, an image belonging to another group is not deleted against the deletion instruction, and there is an effect that the dependency of other groups is not hindered.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, an outline of the album function which is an embodiment of the present invention will be described with reference to FIG.
FIG. 1 shows a state in which the camera 10 and the PC 40 are connected via a USB (Universal Serial Bus) bus 60, and various data can be exchanged. In the present embodiment, an image captured by the camera 10 is once transferred to the PC 40, an album is created for the image by the PC 40, and the created album is transferred from the PC 40 to the camera 10. Therefore, if the user carries the camera 10, the user can view the album even if the PC 40 is not there.

  1 will be further described. A removable memory card 11 is attached to the camera 10, and various data can be recorded on the memory card 11. The memory card 11 stores an image root folder 12 and an album list file 15, both of which are arranged immediately below the root directory in the recording area of the memory card 11.

  Images captured most recently by the camera 10 are stored in the image storage folder (“100 OLYMP” folder) 13 in the image root folder (“DCIM” folder) 12 in the image data files 14-1, 14-2,. n,... (hereinafter, representatively shown as “14-n”). As will be described later, in the image root folder 12, not only the image most recently taken by the camera 10, but also the image data file for the image registered in the album (included in the album) is particularly shown. Since they are stored without distinction, the file name of the image data file 14-n for the image most recently shot by the camera 10 is stored in the shooting list ("SHOT") 16 shown in the album list file 15. Added in the order of shooting. Therefore, when transferring an image most recently shot by the camera 10 from the camera 10 to the PC 40, the camera 10 searches the image root folder 12 for the image data file 14-n having the file name shown in the shooting list 16. The process of transferring to the PC 40 is performed. In the PC 40, the image data file 14-n sent from the camera 10 is taken image data files 43-1, 43-2, ..., 43-n, ... (hereinafter, represented as "43-n" as a representative). And stored in a photographed image folder (“MYCAMERA” folder) 42. The captured image folder 42 is provided in a storage area of an HDD (Hard Disk Drive) 41 included in the PC 40.

  The album list file (“ALBUM.PVM” file) 15 includes the relationship between each image data file 14-n and the album containing the image data file 14-n (to which the image data file 14-n belongs). The relationship is represented by an album list 17 in which the file names of the files are arranged for each album including the file. In the list of file names in the album list 17, the file name of the image data file for the cover image corresponding to the cover of the album is described at the top. This cover image corresponds to the above-mentioned designated image.

As described above, the album list file 15 also includes the shooting list 16.
In the present embodiment, the number of albums managed in the album list 17 is determined in advance, and names such as “ALBUM1”, “ALBUM2”, “ALBUM3”,. It shall be.

  The album list file 15 is sent from the PC 40 together with the image data file 14-n representing the images included in the album. When the image data file 14-n and the album list file 17 are sent from the PC 40, the camera 10 stores the image data file 14-n in the image storage folder 13 and the album list file 15 for the memory card 11. Overwrite directly under the root directory in the recording area. However, at this time, the shooting list 16 is kept as it is before being overwritten. When a memory card 11 that does not have an album list file 15 is inserted into the camera 10, it is necessary to write information about images taken by the camera 10 in the shooting list 16, so that an album list file 15 is newly generated. Stored in the memory card 11.

  As described above, the management structure of the image data file in the memory card 11 in the camera 10 according to the present embodiment employs the management structure based on the image list file shown in FIG. 17 is characterized in that the file name of the image data file for the cover image corresponding to the cover of the album is written at the top of the file name sequence in FIG.

  In order to simplify the description, it is assumed in the present embodiment that file names of data files having different data contents are not duplicated in the image root folder 12. Therefore, only one image data file 14-n in the image root folder 12 can be specified by only the file names shown in the shooting list 16 and the album list 17. Here, for example, information indicating the file creation date and time, the file name, and the storage location of the file is shown in the shooting list 16 and the album list 17 so that the image data file 14-n is stored in the image root folder 12.

On the other hand, if the result of this determination is No, that is, for the cover image selection instruction button 77 in FIG. 6, the process proceeds to S142.

In S142, a cover image creation screen is opened (displayed on the display unit 56). A cover image creation screen is illustrated in FIG.
In S143, the process of reading all the image data files in the currently referenced album folder is performed. In subsequent S144, a list of album images represented by each of the read image data files is displayed on the display unit 56. Processing to be displayed on the inside cover image creation screen is performed. In the screen example of FIG. 8, this album image list is displayed on the cover image candidate display portion 81. Here, these album images are candidates for the cover image, and when the user performs an operation corresponding to an instruction to temporarily select one of the images on the input unit 54, the image is displayed on the cover image display unit. 82.

  In S145, whether or not an instruction to change a cover image candidate image by changing a folder to be referred to is acquired, or an instruction to change a folder to be referred to by an operation such as clicking on the folder setting unit 83 in the screen example of FIG. The process of determining whether or not has been acquired is performed. If the determination result is Yes, in S146, after referring to the folder related to the acquired instruction, the process returns to S143 and the above-described process is repeated. This process makes it possible to select the cover image of the album that is the target of the album operation from those other than the album images included in the album. On the other hand, if the result of the determination process in S145 is No, the process proceeds to S147.

  In S147, processing is performed to determine whether or not an instruction to determine a cover image has been acquired, and whether or not an operation has been performed on the determination button 84 in the screen example of FIG. If the determination result is Yes, in S148, the file name of the image data file for the image related to the decision instruction is read as an image data file (cover image data file) for the cover image, and temporarily stored in a predetermined area of the RAM 53. In the subsequent S149, the title composition process is performed, and thereafter, the process proceeds to S151. Details of the title composition processing will be described later. In the screen example of the album operation screen shown in FIG. 6, the image displayed on the display image display unit 74 until this time is replaced with the cover image related to this determination instruction.

On the other hand, when the result of the determination process in S147 is No, the process proceeds to S150.
In S150, processing is performed to determine whether or not an instruction to cancel the cover image creation processing has been acquired, and whether or not an operation has been performed on the cancel button 85 in the screen example of FIG. If the determination result is Yes, the process proceeds to S151. If the determination result is No, the process returns to S145 to repeat the above-described process.

In S151, processing for closing (erasing) the cover image creation screen being displayed on the display unit 56 is performed. Thereafter, the cover image creation process is terminated, and the process returns to the album operation process of FIG.
The process so far is the cover image creation process.
Next, the title composition process that is the process of S149 in the cover image creation process described above will be described. FIG. 9 is a flowchart showing the contents of the title composition process.

First, in S161, processing for opening a title input screen (displaying on the display unit 56) is performed. A title input screen is illustrated in FIG.
In S <b> 162, a process for acquiring the input content of the character string corresponding to the operation performed on the input unit 54 by the user is performed. In the screen example shown in FIG. 10, the contents of the character string acquired at this time are displayed on the input text display unit 86.

  In S163, the process of determining whether or not the input of the character string has been completed and an instruction to determine the character string to be used as a title has been acquired, and whether or not the determination button 87 has been operated in the screen example of FIG. 10 is performed. . If the determination result is Yes, the process proceeds to S165. On the other hand, if this determination result is No, in S164, processing is performed to determine whether or not an instruction to cancel the title composition processing has been acquired, and whether or not an operation has been performed on the cancel button 88 in the screen example of FIG. . If the determination result is Yes, the process proceeds to S166. If the determination result is No, the process returns to S162 and the above-described process is repeated.

  In S165, a character string image representing the character string acquired by the process of S162 is generated, and the cover image stored in a predetermined area of the RAM 53 by the process of S147 in the cover image creation process (FIG. 7) described above. The generated character string image is superimposed and synthesized on the cover image represented by the data file, and an image data file for the obtained synthesized image is stored as a cover image data file in the area of the RAM 53 again. . In the screen example of FIG. 10, the character string image having the shape, size, and color set by the character style setting unit 89 is generated.

  In S166, a process for assigning a predetermined file name to the cover image data file stored in a predetermined area of the RAM 53 is performed. In S167, the cover image data file is added to the album folder currently being referred to. The storing process is performed. In the screen example of the album operation screen shown in FIG. 6, the image displayed on the display image display unit 74 until this time is replaced with the display image on which the character composition is performed.

In S168, processing for closing (erasing) the title input screen being displayed on the display unit 56 is performed. Thereafter, the title composition process is terminated, and the process returns to the cover image creation process of FIG.
The above processing is the title composition processing. In this way, by synthesizing the image of the character string representing the title with the cover image, even the camera 10 that does not have font data of characters such as kanji can display the title of the album. Representing characters can also be displayed in various styles.

Next, the album transfer process which is the process of S123 (FIG. 5) in the album operation process described above will be described. FIG. 11 is a flowchart showing the contents of the album transfer process.
First, in S171, processing for obtaining the name of the album corresponding to the album folder currently being referred to is performed.

  In S 172, processing for sending data addressed to the camera 10 indicating a request for sending the album list file 15 stored in the memory card 11 of the camera 10 from the USB I / F 57 is performed. Details of processing performed in the camera 10 that has received this transmission request will be described later.

In S173, processing is performed in which the USB I / F 57 receives and acquires the album list file 15 sent from the camera 10 in response to the request described above.
Although details will be described later, data notifying that the album list file 15 does not exist may be sent from the camera 10 at this time, but when this data is sent, this notification is sent. Processing to receive and acquire is performed. Therefore, in S174, a process for determining whether or not the album list file 15 exists in the camera 10 is performed. Only when the album list file 15 does not exist (the determination result is No), the album list file is determined in S175. 15 is newly created.

  In S176, the list of albums with the album name acquired in the process of S171 in the album list 17 in the album list file 15 is referred to, and the current name is displayed at the end of the list of file names of the image data files indicated in the list. A process of adding the file names of the image data files included in the album folder in the HDD 41 being referred to one by one is performed.

In S177, a process for determining whether or not the image data file of the cover image is stored in the currently referenced album folder is performed. If this determination result is Yes, the process is performed in S178, and if it is No, the process is performed in S181. Proceed.
In S178, a process for determining whether or not a title image transfer instruction has been acquired is performed. If this determination result is Yes, the process proceeds to S180, and if No, the process proceeds to S179. This title image transfer instruction is determined by checking whether or not the album cover image creation check box 80 is checked in the screen example of the album operation screen shown in FIG.

In S179, all of the image data files included in the currently referenced album folder except for the cover image are processed to be sent to the camera 10 from the USB I / F 57, and thereafter, the process proceeds to S182. Proceed with the process.
In S180, the file name of the cover image data file stored in the currently referenced album folder is moved to the top of the list and inserted in the list of albums to which the file name has been added in the process of S176. Processing is performed. By this processing, the file name of the image data file of the cover image is shown at the top of the album list in the album list 17.

  Note that the content of the processing in S180 is changed so that the file name of the image data file of the cover image stored in the currently referenced album folder is moved to the end of the list and inserted, so that the album The cover image can be reproduced and displayed at the end of the sequential image reproduction. This makes it possible to handle the cover image created by the above-described process as if it were the back cover of an album.

In S181, processing for sending all the image data files included in the currently referred album folder to the camera 10 from the USB I / F 57 is performed.
In S182, the album list file 15 in which the file name is added to the album list 17 is sent to the camera 10 from the USB I / F 57, and thereafter, the album transfer process is terminated and the album shown in FIG. Return processing to operation processing.

The process so far is the album transfer process.
Next, control processing performed by the CPU 30 of the camera 10 will be described. All of these processes are realized by the CPU 30 executing a control program stored in the ROM 31.

  First, the album receiving process shown in the flowchart of FIG. 12 will be described. This process is for the camera 10 to receive data relating to the album sent from the PC 40. The above-mentioned album transfer process is executed by the PC 40 and data indicating a request for sending the album list file 15 is sent to the USB I / O. The process starts when the CPU 30 detects that F29 has been received.

  First, in S201, the memory card 11 is searched to determine whether or not the album list file 15 is stored. When it is stored (when the determination result is Yes), the album list is determined in S202. When the file 15 is read out and sent from the USB I / F 29 to the PC 40 and is not stored (when the determination result is No), data for notifying that the album list file 15 does not exist is stored in the PC 40. Is sent to the USB I / F 29. The data transmitted by the process of S202 or S203 is received by the PC 40 that is executing the process of S173 in the album transfer process described above.

In S204, a process is performed in which the USB I / F 29 receives and acquires data sent from the PC 40 in accordance with the data sent in the process of S202 or S203.
In S205, processing for determining whether or not the data acquired by the processing in the previous step is an image data file is performed. If the determination result is Yes, in S206, the acquired image data file is stored in the image storage folder 13 in the image root folder 12 of the memory card 11, and then the process returns to S204. The above process is repeated.

  On the other hand, when the determination result in S205 is No, in S207, a process for determining whether the data acquired by the process in S204 is the album list file 15 is performed. In the PC 40 executing the above-described album transfer process, the album list file 15 is transmitted after all the image data files to be transferred have been transmitted by the processes of S179, S181, and S182 in FIG. If the result of the determination is Yes, it is considered that the album transfer process being executed by the PC 40 has ended, and the process proceeds to S208. On the other hand, if the determination result in S207 is No, the process returns to S204 and the above-described process is repeated.

  In S208, a process of overwriting the album list file 15 acquired in the process of S204 directly under the root directory of the memory card is performed. At this time, however, the shooting list 16 is retained as it is in the album list file 15 before being overwritten. Thereafter, the album receiving process ends.

The process so far is the album reception process.
Next, the album playback process whose process contents are shown in FIG. This process is a process for browsing the album sent from the PC 40 with the camera 10.

  This album playback process is performed when the user operates the operation input unit 32 to display a function selection screen related to album operation as illustrated in FIG. 14A on the display unit 28. It is started when the function “album playback” is selected by further operation.

First, in S211, album selection processing is performed. This process is a process for selecting one to be browsed from among a plurality of albums held by the camera 10, and details thereof will be described later.
In S212, the album list 17 shown in the album list file 15 stored in the memory card 11 is referred to, and the head of the file names arranged in association with the album selected in the process of S211 is displayed. Processing to acquire the thing is performed.

In S213, a process of searching for and acquiring the image data file 14-n having the file name acquired by the process executed immediately before from the image root folder 12 of the memory card 11 is performed.
In S214, an instruction is given to the image processing unit 24 and the display processing unit 27, and processing for causing the display unit 28 to display an image represented by the file acquired in the previous step is performed.

  In S215, a process is performed to determine whether or not an instruction to change the display image on the display unit 28 from the currently displayed one to the one before and after that is performed by the user's operation on the operation input unit 32 is performed. If this instruction is acquired (determination result is Yes), the process proceeds to S216. If this instruction is not acquired (determination result is No), the process proceeds to S217.

  In S216, the album list 17 shown in the album list file 15 stored in the memory card 11 is referred to, and among the file names arranged in association with the album selected in the process of S211, S215 The process of acquiring the order related to the instruction determined to be acquired by the process is performed, and then the process returns to S213 to repeat the above-described process.

  In S217, a process for determining whether or not an instruction for ending album reproduction, which is performed by a user operation on the operation input unit 32, is performed. If this instruction is acquired (determination result is Yes), S218 is performed. In FIG. 14, the album operation function selection screen as shown in FIG. 14A is displayed again, and then the album reproduction process is terminated. On the other hand, if the determination result in S217 is No, the process returns to S215 and the above-described process is repeated.

The process so far is the album playback process.
Next, the album selection process that is the process of S211 in the above-described album reproduction process will be described. FIG. 15 is a flowchart showing the contents of the album selection process.
First, in S221, processing for reading the album list file 15 from the memory card 11 and referring to the album list 17 is performed.

  In S222, a process is performed to determine what is the content of the instruction regarding the display method of the cover image of the album on the display unit 28, which is performed by the user's operation on the operation input unit 32. Here, if the content of the instruction is an instruction to display a list of cover images (index display) of a plurality of albums as illustrated in FIG. 14B, the process proceeds to S223, while the content of the instruction However, if it is an instruction to display the cover images of the album one by one (one frame display) as illustrated in FIG. 14C, the process proceeds to S228.

  In S223, processing for obtaining the first one of the file name sequence of the image data file 14-n for each album in the album list 17 is performed. The head file name is that of the image data file 14-n of the cover image for each album by the process of S180 (FIG. 11) in the album transfer process described above.

In S224, the image data file 14-n having the file name acquired by the process in the previous step is searched for and acquired from the image root folder 12 of the memory card 11, respectively.
In S225, an instruction is given to the image processing unit 24 and the display processing unit 27, and a process of causing the display unit 28 to display the cover image represented by the image data file 14-n acquired by the processing in the previous step is performed. .

  In S226, a process is performed to determine whether or not an instruction to select one of the cover images displayed in a list on the display unit 28 is given by an operation on the operation input unit 32 by the user, and this instruction is given. Until the determination result is Yes (until the determination result is Yes).

  In S227, a process for determining whether or not an instruction for determining selection of one of the instructed cover images has been acquired by an operation on the operation input unit 32 by the user is performed. When the determination result is Yes, the album selection process is terminated and the process returns to the original process. On the other hand, when this determination instruction is not made (when the determination result is No), the process returns to S226 and the above-described process is repeated.

  In S228, the file name of the image data file 14-n for the album name “ALBUM1” in the album list 17 at the head, that is, the file name of the image data file 14-n that is the cover image for this album. The process of acquiring is performed.

In S229, a process of searching for and acquiring the image data file 14-n having the file name acquired by the process executed immediately before from the image root folder 12 of the memory card 11 is performed.
In S230, an instruction is given to the image processing unit 24 and the display processing unit 27, and a process of causing the display unit 28 to display the cover image represented by the image data file 14-n acquired by the processing in the previous step is performed.

  In S231, a process is performed to determine whether or not an instruction to select another album different from the album whose representative image is being displayed on the display unit 18 is acquired by an operation on the operation input unit 32 by the user. When the instruction is acquired (when the determination result is Yes), in S232, the first one in the file name sequence of the image data file 14-n for the album according to the instruction in the album list 17 is acquired. The process is performed, and then the process returns to S229 to repeat the above-described process.

  On the other hand, if such an instruction has not been acquired in S231 (when the determination result is No), the selection of one of the instructed cover images is determined by an operation on the operation input unit 32 by the user in S233. A process is performed to determine whether or not an instruction to be acquired has been acquired. Here, when this determination instruction is given (when the determination result is Yes), the album selection process is terminated and the process returns to the original process. On the other hand, when this determination instruction is not made (when the determination result is No), the process returns to S231 and the above-described process is repeated.

The process so far is the album selection process.
Various processes described above are performed by the CPU 51 of the PC 40 and the CPU 30 of the camera 10 respectively, thereby managing the relationship between the album and the cover image of the album while suppressing consumption of the recording amount of the memory card 11. Will be able to.

Next, the image album registration processing whose processing contents are shown in the flowchart of FIG. 16 will be described. This process is a process for additionally registering a photographed image or an image included in another album to the album.
The image album registration process is started when the user operates the operation input unit 32 and gives an instruction to execute the process.

  First, in S301, a process for determining where the image that is the target of the additional registration related to the instruction is located is performed. Here, if it is determined that the instruction is to additionally register a photographed image, in S302, the photograph list 16 included in the album list file 15 stored in the memory card 11 is selected as the selection result. After that, the process proceeds to S304. On the other hand, if it is determined in S301 that the instruction includes the image included in the album as an additional registration target, the above-described album selection process (FIG. 15) is executed in S303, and the execution result is as follows. One of the albums shown in the album list 17 included in the album list file 15 is selected.

In S304, a target image specifying process is performed. This process is a process for specifying an image to be additionally registered among the file names of the image data files shown in the selected list, and details of the process will be described later.
In S305, the file name of the image data file 14-n representing the image specified in the process of the previous step is selected from the shooting list 16 selected in the process of S302 or the album selection process in S303 of the album list 17. The process of reading from the list for the album selected by is performed.

In S306, the above-described album selection process (FIG. 15) is executed again, and one of the albums shown in the album list 17 included in the album list file 15 is selected as the execution result.
In S307, the file name read out in the process of S305 is added to the end of the list of the album list 17 selected by the album selection process in S306 (the arrangement of the file names of the image data file 14-n). After that, the image album registration process ends.

The above processing is the image album registration processing.
Next, the target image specifying process which is the process of S304 in the album registration process described above will be described. FIG. 17 is a flowchart showing the contents of the target image specifying process. As can be seen from a comparison of FIG. 17 with FIG. 15, the processing content of the target image specifying process is similar to the processing content of the album selection process described above.

First, in S311, processing for referring to a list of albums selected by the album selection processing in S303 out of the shooting list 16 or album list 17 selected by the processing in S302 is performed.
In S <b> 312, processing is performed to determine what is the content of the instruction regarding the display method of the image on the display unit 28 performed by the user's operation on the operation input unit 32. Here, if the content of the instruction is an instruction to display a plurality of images as a list (index display), the process proceeds to S313, while the content of the instruction displays images one by one (one frame display). If it is an instruction, the process proceeds to S318.

  In S313, processing for sequentially acquiring the file names shown in the selected list is performed, and in subsequent S224, the image data file 14-n that is the acquired file name is stored in the image of the memory card 11. A process of finding and acquiring each from the root folder 12 is performed.

In S315, an instruction is given to the image processing unit 24 and the display processing unit 27, and a process for causing the display unit 28 to display the cover image represented by the image data file 14-n acquired by the processing in the previous step is performed. .
In S316, a process for determining whether or not an instruction to select one of the images displayed in the list on the display unit 28 is given by an operation on the operation input unit 32 by the user is performed. The process of S317 is repeated until (until the determination result is Yes).

  In S317, a process for determining whether or not an instruction to determine selection of one of the instructed images has been acquired by an operation on the operation input unit 32 by the user is performed, and when this determination instruction is made ( When the determination result is Yes), the target image specifying process is terminated and the process is returned to the original process. On the other hand, when this determination instruction is not made (when the determination result is No), the process returns to S316 and the above-described process is repeated.

In S318, a process for obtaining the first one of the list of file names shown in the selected list is performed.
In S319, a process of searching for and acquiring the image data file 14-n having the file name acquired by the process executed immediately before from the image root folder 12 of the memory card 11 is performed.

In S320, an instruction is given to the image processing unit 24 and the display processing unit 27, and a process of causing the display unit 28 to display the cover image represented by the image data file 14-n acquired by the processing in the previous step is performed.
In S321, the user operates the operation input unit 32 to select an image having a file name that is the order before and after the file name of the image data file representing the image currently displayed on the display unit 18 in the selected list. When a process for determining whether or not an instruction to acquire is acquired is performed and this instruction is acquired (when the determination result is Yes), the file names in the order according to the instruction in the list selected in S322 After that, the process is returned to S319 and the above-described process is repeated.

  On the other hand, if such an instruction has not been acquired in S321 (when the determination result is No), it is determined in S323 that an image displayed on the display unit 18 is selected by an operation on the operation input unit 32 by the user. A process is performed to determine whether or not an instruction to be acquired has been acquired. Here, when this determination instruction is given (when the determination result is Yes), this target image specifying process is terminated and the process returns to the original process. On the other hand, when this determination instruction is not made (when the determination result is No), the process returns to S321 and the above-described process is repeated.

The process up to this point is the target image specifying process.
Next, a method for deleting the image data file 14-n stored in the image root folder 12 of the memory card 11 will be described with reference to FIG.
FIG. 18 shows the data contents of the album list file 15 and the storage status of the image data file 14-n in the image root folder 12, both stored in the memory card 11, together with this storage. In the situation, a display screen when a photographed image or album image is displayed as a list on the display unit 58 is schematically shown.

  In each of (a), (b), and (c) of FIG. 18, among the data contents of the album list file 15, the shooting list 16 shows the contents as it is, and the album list 17 includes “album” A list of the album “A” is shown with a symbol “17-A”. The photographed image list display 91 shows a photographed image list display screen displayed on the display unit 28 based on the contents of the list of the photographed list 16 at that time. Shows a list display screen of album images displayed on the display unit 28 based on the contents of the list of the album list 17-A of “Album A” at that time.

In this example, it is assumed that the camera 10 has no album other than “album A”.
FIG. 18A shows an example of the storage status before the image data file 14-n is deleted.

  In the example of (a), the arrangement of the file names of the image data files 14-n shown in the shooting list 16 is “P001, P002,..., P005, P006, P007,. In this case, the captured image list display 91 is a list of images represented by the image data file 14-n with these file names. In this example, the file name sequence of the image data file 14-n shown in the album list 17-A of “Album A” is “P001, P003, P004, P006, P009,..., P020”. In this case, the image list display 92 of “album A” is a list of images represented by the image data file 14-n to which these file names are attached. At this time, the image storage folder 13 in the image root folder 12 has file names “P001, P002, P003, P004, P005, P006, P007,..., P009,..., P012,. The stored image data file 14-n is stored.

In this state (a), the state after data operation is performed on the data in the memory card 11 in response to an instruction to delete the captured image “P006” made by the user of the camera 10 is shown. This is the state (b).
In the transition from (a) to (b), the file name “P006” is deleted from the shooting list 16. Therefore, at this time, the captured image “P006” is deleted from the captured image list display 91. However, in (a), “P006” is also included in the album list 17-A of “Album A” as an album image, and at this time, the image of the image data file 14-n for “P006”. Deletion from the root folder 12 is not performed. Therefore, even at this time, the image display of “P006” is possible, and the image “P006” is actually displayed in the image list display 92 of “album A”.

Thereafter, in this state (b), after data manipulation is performed on the data in the memory card 11 in response to an instruction from the user of the camera 10 to delete the album image “P006”. The state shown in (c) is shown.
In the transition from (b) to (c), the file name “P006” is also deleted from the album list 17-A of “album A”. Accordingly, at this time, the album image “P006” is also deleted from the image list display 92 of “album A”. As a result, the file name “P006” does not exist in either the shooting list 16 or the album list 17-A of “album A”. Therefore, in this case, the image data file 14-n for “P006” is deleted from the image root folder 12.

  As described above, the image data file 14-n having the file name is deleted after the file name no longer exists from either the shooting list 16 or the list for each album shown in the album list 17. By doing so, it is possible to appropriately delete the image data file 14-n when the same image is duplicated in a plurality of lists.

Hereinafter, a process performed by the CPU 30 to enable the camera 10 to delete the image data file 14-n described above will be described.
First, FIG. 19 will be described. This figure shows the processing contents of the photographed image deletion processing in a flowchart. In this process, when an instruction to delete a photographed image from the user is acquired, the file name for the photographed image according to the instruction is deleted from the photography list 16 and the file name is not shown in the album list 17. This is a process of deleting the image data file 14-n having the file name from the image root folder 12 only. That is, by this process, it is possible to appropriately delete the image data file 14-n even when the photographed image related to the deletion instruction acquired from the user is included in the album as an album image.

This process starts when the user operates the operation input unit 32 to give an instruction to delete a captured image.
First, in S331, a process of selecting the shooting list 16 from the album list file 15 stored in the memory card 11 is performed, and in the subsequent S332, the above-described target image specifying process (FIG. 17) is executed and the target of deletion is performed. The captured image is identified.

In S333, a process of reading the file name of the captured image specified by the process in the previous step from the shooting list 16 is performed.
In S334, a process of acquiring an instruction to confirm execution of deletion of a captured image performed by the user operating the operation input unit 32 is performed. In subsequent S335, it is determined whether or not this instruction indicates cancellation of the deletion process. A determination process is performed. Here, if the determination result is Yes, the captured image deletion process is immediately terminated. On the other hand, if this determination result is No, in S336, it is determined whether or not this instruction indicates execution of deletion. If this determination result is Yes, the process proceeds to S337. In the meantime, the processing is returned to S334 and the above-described processing is repeated.

In S337, a process of deleting the file name read out in the process of S333 from the shooting list 16 is performed.
In S338, it is determined whether or not the file name read from the shooting list 16 by the process of S333 exists in the list of file names of the image data file 14-n for each album in the album list 17 of the album list file 15. If the determination process is performed and the file name exists in the album list 17 (if the determination result is Yes), the captured image deletion process is terminated as it is. On the other hand, if the file name does not exist in the album list 17 (if the determination result is No), the image data file 14-n having the file name is searched from the image root folder 12 and deleted in S339. Processing is performed. Thereafter, after the process of S339 is completed, the photographed image deletion process is terminated.

The process so far is the photographed image deletion process.
Next, FIG. 20 will be described. This figure shows the processing contents of the album image deletion processing in a flowchart. In this process, when an instruction to delete an album image from the user is acquired, the file name for the album image according to the instruction is deleted from the album list 17, and the file name is changed between the shooting list 16 and the album list 17. This is a process of deleting the image data file 14-n having the file name from the image root folder 12 only when it is not shown in any of them. That is, by this process, even when the album image related to the deletion instruction acquired from the user is a photographed image or an album image included in another album, the image data file 14-n is appropriately stored. Can be deleted.

  This album image deletion processing is performed when the user operates the operation input unit 32 to display a function selection screen related to album operation as illustrated in FIG. 21A on the display unit 28. This is started when the function “deregistration” is selected by a further operation on.

First, in S341, the above-described album selection process (FIG. 15) is executed to select an album that includes an album image to be deleted.
In subsequent S342, the above-described target image specifying process (FIG. 17) is executed to specify a captured image to be deleted. FIG. 21B shows a screen example of an album image list display screen displayed on the display unit 28 of the camera 10 by the process of S315 in the target image specifying process, and the album displayed on the display unit 28 by the process of S320. FIG. 21 (c) shows a screen example of an image single frame display screen.

In S343, a process of reading the file name of the album image specified by the process of the previous step from the list for the album selected by the process of S341 in the album list 17 is performed.
In S344, processing for obtaining an instruction to confirm execution of album image deletion performed by the user by operating the operation input unit 32 is performed. In subsequent S345, it is determined whether or not this instruction indicates cancellation of the deletion processing. A determination process is performed. If the determination result is Yes, the album image deletion process is immediately terminated. On the other hand, if this determination result is No, a process for determining whether or not this instruction indicates execution of deletion is performed in S346, and if this determination result is Yes, the process proceeds to S347. In the meantime, the process returns to S344 and the above-described process is repeated.

FIG. 21D shows a screen to be displayed on the display unit 28 in order to instruct to cancel the album image deletion process, and to the display unit 28 to instruct the execution of the album image deletion. A screen to be displayed is shown in FIG.
In S347, a process of deleting the file name read out in the process of S343 from the list for the album selected in the process of S341 in the album list 17 is performed.

  In S348, a process of determining whether or not the file name read from the album list 17 by the process of S343 exists in the file name list of the image data file 14-n for each album in the album list 17 is performed. If at least one of the file names exists in the album list 17 (if the determination result is Yes), the album image deletion process is terminated as it is. On the other hand, if no file name exists in the album list 17 (if the determination result is No), the process proceeds to S349.

  In S349, a process for determining whether or not the file name read from the album list 17 by the process of S343 exists in the shooting list 16 is performed. If the file name exists (the determination result is Yes). If so, the album image deletion process is terminated as it is. On the other hand, if the file name does not exist in the shooting list 16 (if the determination result is No), the image data file 14-n having the file name is searched from the image root folder 12 and deleted in S350. Processing is performed. Thereafter, after the process of S350 is completed, the album image deletion process is terminated.

The above processing is the album image deletion processing.
In the embodiment described above, the album including the display of the representative image is reproduced by the camera 10, but each processing shown in FIG. 11 and FIG. 12 is performed by the CPU 51 of the PC 40.
