Then, when judging that the overlapping priority order information is included, the recorded priority order information of the non-specified data to which the overlapping priority order information is allocated is updated so that the allocated priority order information and the recorded priority order information do not overlap while keeping the priority order for the data output of the non-specified data. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a data recording apparatus and a data recording program for recording data on a storage medium.

  The following image data duplication methods are known. In this image data duplication method, when duplicating image data, the file names are changed so that the file names of the image data are in the specified order (for example, Patent Document 1).

JP 2001-229061 A

  However, according to the conventional method, when the file name of the image data is changed in order to change the priority for data output, the image data needs to be duplicated, so that the capacity required for recording the image data is increased. There was a problem of increasing.

According to the present invention, in order to record a plurality of data, each of which is assigned priority information indicating a priority for data output, on a storage medium, one data is specified, and priority information is specified in the specified specific data. In the priority information (recording priority information) assigned to the non-specific data that is data other than the specific data recorded in the storage medium, the priority information (allocation priority information) of the specific data ) And whether or not priority information that overlaps is included. If it is determined that overlapping priority information is included, allocation is performed while maintaining the priority for data output of non-specific data. Update the recording priority information of the non-specific data to which the overlapping priority information is assigned so that the priority information and the recording priority information do not overlap. The features.
In the present invention, the priority for data output is represented by a number constituting the file name of the data file storing the data, and a file name including a number corresponding to the priority is assigned to specific data as priority information. May be.
Also, it is determined whether there is a file name that overlaps the file name of the specific data in the file name of the non-specific data. If it is determined that there is a duplicate file name, If the file name of the non-specific data after adding 1 to the number constituting the file name and further adding 1 overlaps with the file name of other non-specific data, the file name of the other non-specific data It is preferable to add 1 to the number that constitutes and repeat this until there are no duplicate file names.
After repeating the process until there are no duplicate file names, specify the file names of the specific data and non-specific data so that the numbers constituting the file names of the specific data and non-specific data are arranged in ascending order from the highest priority. You may make it update.
Specify one data specified by the user as specific data from multiple data recorded on the storage medium, and specify the priority of the specific data to be the priority specified by the user Priority information may be assigned to data.
Priority is given to specific data so that image data is acquired by capturing a subject image, the acquired image data is specified as specific data, and the priority for output of specific data is the priority specified by the user. Information may be assigned.
Image data is obtained by capturing a subject image, and among the acquired image data, those specified by the user to increase the priority for data output are specified as specific data, and priority for output of specific data is specified. The priority information may be assigned to the specific data so that the priority is the priority specified by the user.
At this time, among the acquired image data, for the image data not designated by the user to increase the priority for data output, a plurality of data output priorities recorded in the storage medium are stored. The priority order information may be assigned so as to be the lowest in the data.

  According to the present invention, the priority for data output can be changed without increasing the capacity required for data recording.

-First embodiment-
FIG. 1 is a block diagram showing a configuration of an embodiment of a camera (imaging device) in the first embodiment. The camera 100 includes an operation member 101, a lens 102, an image sensor 103, a control device 104, a memory card slot 105, and a monitor 106. The operation member 101 includes various input members operated by the user, such as a power button, a release switch, a zoom button, a cross key, a determination button, a playback button, and a delete button.

  The lens 102 is composed of a plurality of optical lens groups, but is represented by a single lens in FIG. The image sensor 103 is, for example, a CCD or a CMOS, and captures a subject image formed by the lens 102 to acquire an image. The acquired image data (image data) is output to the control device 104. The control device 104 compresses the image data acquired by the image sensor 103 into a predetermined image format, for example, JPEG format, and generates an image file in a predetermined format such as Exif (Exchangeable Image File Format Digital Still Camera). Output to the memory card slot 105.

  The memory card slot 105 is a slot for inserting a memory card as a storage medium, and the image file output from the control device 104 is written and recorded on the memory card. Further, based on an instruction from the control device 104, an image file stored in the memory card is read.

  The monitor 106 is a liquid crystal monitor (rear monitor) mounted on the back surface of the camera 100, and the monitor 106 displays an image stored in a memory card, a setting menu for setting the camera 100, and the like. .

  The control device 104 includes a CPU, a memory, and other peripheral circuits, and functionally includes a display control unit 104a, a priority order changing unit 104b, and a file name updating unit 104c. The memory constituting the control device 104 includes a ROM used as a buffer memory, such as a flash memory, and a RAM, such as an SDRAM.

  When the user presses the operation member 101, for example, the playback button, the display control unit 104 a reads images stored in the memory card via the memory card slot 105 and displays a list on the monitor 106. As a list display method, for example, thumbnail images can be displayed as a list, or file names of images can be displayed as a list.

  In the present embodiment, a file name uniquely assigned according to a predetermined naming rule is added to the image file stored in the memory card. For example, when a file name combining a predetermined character string and a number is added to an image file, 1 is added to the number every time an image is photographed, and the number part constituting the file name is serialized. To avoid duplication of file names. The number part constituting the file name is also used as priority order information when outputting the image, and the display control unit 104a monitors the image 106 in ascending order of the number constituting the file name (in ascending order of the file name). To display.

  For example, a case where the file name is composed of a character string “DSCN” and a 4-digit number will be described. In this case, the file names are represented as “DSCN0001” and “DSCN0002”. As described above, since the numerical part represents the priority order when outputting the images, when there are image files with the two file names, the image file with the file name “DSCN0001” has the priority order. (Output priority) is high, and the display order of this image file is ahead of “DSCN0002”.

  In the present embodiment, the user can change the priority at the time of image output determined based on the file name of the image in this manner by operating the operation member 101. For example, while the thumbnail list or the file name list is displayed on the monitor 106 in order of priority, that is, in ascending order of the file name, the user operates one of the thumbnail images or the file name with the cross key. Select the image and press the enter button to confirm the image selection. Thereafter, the cross key is further operated to select a position in the list where the selected image is to be inserted, and by pressing the enter button, the changed priority order for the image is determined. Note that the user can repeatedly perform the above-described processing to instruct priority order change for a plurality of images at once. When the instruction is completed, the user confirms the instruction by pressing the enter button.

  The priority changing unit 104b obtains the file name information of the image file recorded on the memory card when an instruction to change the priority is given by the user. For example, the priority changing unit 104b reads the file system information (FAT information) of the memory card and acquires a file name list of image files recorded on the memory card as the file name information.

  Then, the priority order changing unit 104b specifies one image among the images instructed to change the priority order based on the priority order change instruction from the user, and prioritizes the specified image (specific image). The order is changed to a new priority order changed by the user. That is, the file name of the specific image is changed to a file name corresponding to the new priority order on the RAM. In addition, which image is specified as the specific image among the images instructed to change the priority will be described later. Hereinafter, until the file name update unit 104c described later updates the file name of the image file recorded in the memory card, all file names are changed on the RAM, and the file name of the actual image file is changed. Is not rewritten.

  Further, the priority order changing unit 104b does not duplicate the file name according to the new priority order of the specific image with the name of another image file stored in the memory card, that is, the file name of a non-specific image other than the specific image. To check. As a result, when it is determined that the file name is duplicated, the duplicate file name is changed so as not to duplicate the new file name of the specific image.

  Specifically, the priority changing unit 104b decreases the priority of the corresponding non-specific image by 1 by adding 1 to the numerical part of the file name of the non-specific image whose file name overlaps with the specific image. Eliminate duplicate file names. As a result, the file name of the non-specific image whose priority has been changed may overlap with the file name of any other non-specific image. In this case, the priority changing unit 104b adds 1 to the numeric part of the file name of another non-specific image in order to eliminate the duplication of the file name, and keeps on the RAM until the duplication of the file name is eliminated. Repeat this.

  When the priority order changing process for one specific image is completed, the priority order changing unit 104b processes the other images for which the priority order has been instructed by the user in the same manner for each image. Will change. As a result, the file name of the image whose priority is instructed by the user is changed to a file name according to the priority specified by the user while avoiding duplication with the file names of other images. be able to.

  FIG. 2 is a diagram showing a specific example of the file name change process in the present embodiment. First, it is assumed that 14 image files with file names added are stored in the memory card as shown in FIG. 2A, and the file name list shown in FIG. It is assumed that the name information is read on the RAM. As described above, as a result of the display control unit 104a displaying a list of information indicating the 14 image files, for example, thumbnail images and file names on the monitor 106, as indicated by arrows A, B, and C by the user. It is assumed that a change of priority is instructed.

  That is, the change instruction A for changing the priority order of “DSCN0005” to a lower order of “DSCN0001”, the change instruction B for changing the priority order of “DSCN0003” to a lower order of “DSCN0181”, and the priority of “DSCN0182”. It is assumed that a change instruction C for changing the rank to a lower order of “DSCN0185” is given.

  As described above, when a priority change is instructed for a plurality of image files, the priority change unit 104b first performs change processing in order from a change instruction in which the priority of the change destination is lower. . That is, in the example shown in FIG. 2A, processing for each change instruction is performed in the order of change instruction C, change instruction B, and change instruction A.

  As shown in FIG. 2B, the priority order changing unit 104b specifies “DSCN0182” as a specific image in accordance with the change instruction C, and moves the priority order of the specific image to a position below “DSCN0185”. That is, the file name of the specific image is changed from “DSCN0182” to “DSCN0186” on the RAM. As a result, since an image with a file name “DSCN0186” already exists in the non-specific image, the file name is duplicated. Therefore, as shown in FIG. 2C, the priority changing unit 104b adds 1 to the file name of the non-specific image having the duplicate file name, that is, the number portion of “DSCN0186”, and changes the file name to “DSCN0187”. .

  Furthermore, since “DSCN0187” already exists in the non-specific image, the priority changing unit 104b changes the conventional “DSCN0187” to “DSCN0188” to eliminate duplication of the file name. “DSCN0188” is changed to “DSCN0189”. As a result, as shown in FIG. 2C, the priority order can be changed based on the change instruction C, that is, the file name can be changed while the duplication of the file name is eliminated.

  Next, as shown in FIG. 2D, the priority changing unit 104b specifies “DSCN0003” as a specific image in accordance with the change instruction B, and moves the priority of the specific image to a lower order of “DSCN0181”. That is, the file name of the specific image is changed from “DSCN0003” to “DSCN0182” on the RAM. In this case, since the original file name “DSCN0182” does not exist by the process based on the change instruction C described above, the file name of the specific image after the change and the file name of the non-specific image overlap. Does not occur. Therefore, the priority changing unit 104b ends the process based on the change instruction B without changing the file name of the non-specific image. Thereby, as shown in FIG. 2E, the priority order based on the change instruction B, that is, the file name can be changed.

  Next, as shown in FIG. 2 (f), the priority changing unit 104 b specifies “DSCN0005” as a specific image in accordance with the change instruction A, and moves the priority of the specific image to a position below “DSCN0001”. That is, the file name of the specific image is changed from “DSCN0005” to “DSCN0002” on the RAM. As a result, since an image with the file name “DSCN0002” already exists in the non-specific image, the file name is duplicated. Accordingly, as shown in FIG. 2G, the priority changing unit 104b adds 1 to the file name of the non-specific image having the duplicate file name, that is, the number portion of “DSCN0002”, and changes the file name to “DSCN0003”. .

  Furthermore, the priority changing unit 104b checks whether the file name “DSCN0003” exists in the non-specific image. Here, “DSCN0003” no longer exists due to the processing based on the change instruction B described above, and therefore, there is no more overlap between the file name of the changed specific image and the file name of the non-specific image. Therefore, the priority changing unit 104b ends the process based on the change instruction A here. Thereby, as shown in FIG. 2G, the priority order based on the change instruction A, that is, the file name can be changed.

  When the file name changing process as described above is performed, duplication of the file name can be avoided, but when the file names are arranged in ascending order (or descending order), an empty number is created in the numeric part. For example, in the example shown in FIG. 2G, “DSCN0005” is an empty number, and the numbers from “DSCN0006” to “DSCN0181” are skipped. For this reason, in this embodiment, there is provided a serial number update mode for updating in a batch so that the numerical parts of the file names after changing the priority order are serial numbers. Is set to the sequential number update mode, the priority level changing unit 104b sets the file names so that the numerical parts of the file names are arranged in ascending order from the highest priority on the RAM. Re-shake.

  Specifically, as shown in FIG. 2H, the file names after “DSCN0005” are reassigned so that “DSCN0001” to “DSCN0014” are assigned in order from the file with the highest priority. As a result, serial numbers corresponding to the priority order can be included in the file name, and image management becomes easy. If the mode of the camera 100 is not set to the sequential number update mode, the file name after the change of priority is determined in the state shown in FIG. Also, here, an example has been described in which the file name is reassigned when the serial number update mode is set. However, the present invention is not limited to this, and the file name becomes a serial number when the priority change is completed. Thus, the user may be inquired whether or not to reassign.

  The file name update unit 104c updates the file name of the image file stored in the memory card with the file name stored in the RAM, and reflects the result of changing the priority order by the above-described processing in the actual file name. To do. Thereby, the file name of each image file can be updated to a file name reflecting the priority changed by the user.

  Thereafter, the display control unit 104a redisplays the thumbnail list or the file name list displayed on the monitor 106 so that the output order is in accordance with the changed priority order.

  FIG. 3 is a flowchart showing the processing of the camera 100 in the first embodiment. The processing shown in FIG. 3 is executed by the control device 104 as a program that is activated when a priority change is instructed by the user.

  In step S10, the priority changing unit 104b reads the file name information of the image file stored in the memory card on the RAM, and proceeds to step S20. In step S20, as described above with reference to FIG. 2, the priority order changing unit 104b selects, as unprocessed change instructions, a priority order change instruction that results in the lowest priority order after the change. To do. Then, the specific image is specified based on the change instruction, and the process proceeds to step S30.

  In step S30, the priority order changing unit 104b executes a file name changing process described later with reference to FIG. 4 so that the priority order of the specific image specified in step S20 is the priority order based on the change instruction. Change the file name of. As a result of changing the file name of the specific image, if the new file name of the specific image and the file name of the non-specific image are duplicated, the file name of the non-specific image is changed until there is no duplicate file name. Go. Thereafter, the process proceeds to step S40.

  In step S40, the priority order changing unit 104b determines whether the file name changing process has been completed for all the change instructions. For example, in the example described above with reference to FIG. 2, it is determined whether or not the processing has been completed for all the change instructions A to C. If a negative determination is made, the process returns to step S20 to repeat the process. On the other hand, if a positive determination is made, the process proceeds to step S50.

  In step S50, the priority changing unit 104b determines whether or not the mode of the camera 100 is set to the serial number update mode described above. If a negative determination is made, the process proceeds to step S70 described later. On the other hand, if an affirmative determination is made, the process proceeds to step S60, and the priority order changing unit 104b increases the numerical part of the file name in ascending order from the highest priority on the RAM as shown in FIG. Rename the file so that Thereafter, the process proceeds to step S70.

  In step S70, the file name update unit 104c updates the file name of the image file stored in the memory card with the file name stored in the RAM, and reflects the result of changing the priority order in the actual file name. To do. Thereafter, the process proceeds to step S80, and the display control unit 104a redisplays the thumbnail list or the file name list on the monitor 106 so that the output order is in accordance with the changed priority order. That is, the thumbnail list or the file name list is redisplayed on the monitor 106 in the ascending order of the file names. Thereafter, the process ends.

  FIG. 4 is a flowchart showing the flow of the file name change process executed in step S30. In step S31, the priority order changing unit 104b changes the file name of the specific image on the RAM to a file name corresponding to the changed priority order based on the processing target change instruction selected in step S20 of FIG. .

  Thereafter, the process proceeds to step S32, and the priority order changing unit 104b determines whether or not the file name after the change of the specific image and the file name of the non-specific image are duplicated based on the file name information that has been read into the RAM. To check. If it is determined that there is a duplication, the process proceeds to step S33, 1 is added to the numeric part of the file name of the non-updated image with the duplicate file name to avoid duplication, and the process returns to step S32.

  Thereafter, in step S32, the priority changing unit 104b checks again whether the file name of the non-updated image whose file name has been changed overlaps with the file name of the other non-updated image. Step S33 is repeated. If it is determined that the file names do not overlap, the process returns to the process described above with reference to FIG.

According to the first embodiment described above, the following operational effects can be obtained.
(1) The priority changing unit 104b specifies one image as a specific image based on a priority change instruction from the user, and assigns a file name as priority information based on the change instruction to the specific image. Then, it is determined whether or not the file name of the non-specific image that is an image other than the specific image recorded on the memory card includes a duplicate of the file name assigned to the specific image. Update the file name of the non-specific image so that the file name of the specific image and the file name of the non-specific image do not overlap while preserving the priority of the non-specific image. I tried to do it. Thus, the file name of the specific image can be changed to a file name corresponding to the priority order based on the change instruction by the user while avoiding duplication of the file name.

(2) The priority order for data output is expressed by the numerical part constituting the image file. As a result, the priority can be changed only by changing the numerical part, and the processing can be simplified. Also, when determining the level of priority, the determination can be made based on the magnitude relationship of the numbers, so that the processing can be simplified.

(3) If the priority order changing unit 104b determines that there is a duplicate of the file name of the specific image in the file name of the non-specific image, the number constituting the file name of the duplicate non-specific image If 1 is added to the part and the file name of the non-specific image after adding 1 is duplicated with the file name of another non-specific image, 1 is added to the file name of the other non-specific image This is repeated until there are no duplicate file names. Thereby, duplication of file names can be surely eliminated.

(4) When the mode of the camera 100 is set to the sequential number update mode, the priority changing unit 104b repeats the process until there are no duplicate file names, and then the file names of the specific image and the non-specific image The file names of the specific image and the non-specific image are updated so that the numbers constituting the are serial numbers and arranged in ascending order from the highest priority. As a result, serial numbers corresponding to the priority order can be added as file names, and image management becomes easy.

(5) One of images specified by the user from a plurality of images recorded on the storage medium, that is, a thumbnail list or a file name list is specified as a specific image, and the priority order of the specific image A file name as priority information is assigned to a specific image so that is a priority specified by the user. As a result, the user can arbitrarily select an image whose priority is to be changed.

-Second embodiment-
In the second embodiment, every time shooting is performed, an instruction to change priority is received by the user, and when the priority is changed by the user, an image (captured image) obtained by shooting is acquired. A method for adding a file name so that the priority order is the highest will be described. In the second embodiment, the block diagram of the camera 100 shown in FIG. 1 and the file name change process shown in FIG. 4 are the same as those in the first embodiment, and thus the description thereof is omitted.

  FIG. 5 is a diagram showing a specific example of the file name change process in the present embodiment. First, it is assumed that 10 image files with file names added are stored in the memory card as shown in FIG. 5A, and the file name list shown in FIG. It is assumed that the name information is read on the RAM.

  At this time, when the user gives an instruction to capture an image and image data is input from the image sensor 103, the control device 104 generates an image file as described above. Then, the priority changing unit 104b gives a priority change instruction (priority increase instruction) from the user to the captured image for a certain period of time after shooting, for example, while confirming and displaying the captured image on the monitor 106. Accept. During this time, the user can instruct a change in the priority order of the captured image by performing a predetermined operation such as pressing and holding the enter button.

  When there is a priority change instruction from the user, the priority change unit 104b specifies the captured image as the specific image, and sets the priority of the specific image in the memory card as shown in FIG. Set the highest value among the stored images. That is, the priority changing unit 104b sets the file name of the specific image to “DSCN0001” and writes it in the file information recorded on the RAM.

  As a result, as shown in FIG. 5B, since the file names of the specific image and the non-specific image whose file name is “DSCN0001” overlap, the priority changing unit 104b The file name is changed to “DSCN0002” by adding 1 to the numeric part. Furthermore, since the file name of the non-specific image after the change overlaps with the file name of the non-specific image whose file name has been “DSCN0002” until now, the file name of the non-specific image is changed to “DSCN0003”. Thereafter, as shown in FIG. 5C, the priority order changing unit 104b sequentially adds 1 to the numerical portion of the file name of the non-specific image until there is no duplication of the file name. Decrease the priority one by one.

  After that, as shown in FIG. 5D, when a further image is taken and the user gives a priority change instruction for the image, the priority change unit 104b sets the file name of the image to “DSCN0001”. To "". Then, as shown in FIG. 5E, 1 is similarly added to the numeric part of the file name of the non-specific image. As a result, the priority of the image designated by the user to increase the priority can be made highest, and the file name of each file can be prevented from being duplicated.

  On the other hand, when there is no priority order change instruction from the user when the image is taken, the priority order changing unit 104b sets the lowest priority order of the captured image. That is, as shown in FIG. 5F, the file name of the image that is currently set with the lowest priority is identified by referring to the file name information stored in the RAM, and the numerical portion of the file name Is added to the image file of the captured image.

  FIG. 6 is a flowchart illustrating processing of the camera 100 according to the second embodiment. The process shown in FIG. 6 is executed by the control device 104 as a program that starts when shooting is instructed by the user. In FIG. 6, steps having the same processing contents as those in FIG. 3 described above in the first embodiment are assigned the same step numbers and description thereof is omitted, and differences will be mainly described.

  In step S <b> 1, the control device 104 controls the image sensor 103 to capture a subject image and obtain an image. Thereafter, the process proceeds to step S2, and the control device 104 performs image processing on the image data input from the image sensor 103, generates an image file as described above, and proceeds to step S3. In step S <b> 3, the display control unit 104 a outputs the acquired image to the monitor 106 for a certain period of time and displays a confirmation image on the monitor 106.

  Thereafter, the process proceeds to step S10, and the priority order changing unit 104b reads the file name information of the image file stored in the memory card on the RAM, and proceeds to step S11. In step S11, the captured image is specified as a specific image, and the process proceeds to step S12. In step S12, the priority order changing unit 104b determines whether or not there is an instruction to change the priority order of the captured image from the user during the display of the confirmation image.

  If it is determined that there has been a priority order change instruction, the process proceeds to step S21, and the priority order changing unit 104b sets the priority order after the change of the specific image to be the highest among the images stored in the memory card. The process proceeds to step S30. On the other hand, if it is determined that there is no priority order change instruction, the process proceeds to step S22, and the priority order changing unit 104b sets the priority order after the change of the specific image to the lowest among the images stored in the memory card. Then, the process proceeds to step S23. In step S23, as shown in FIG. 5F, the file name corresponding to the lowest priority is added to the captured image, and the process proceeds to step S71.

  In step S71, the image file of the captured image to which the file name is added is recorded on the memory card, and the process ends.

According to the second embodiment described above, the following effects can be obtained in addition to the functions and effects of the first embodiment.
(1) Among the captured images, an image instructed to increase the priority by the user is specified as a specific image, and an instruction to change (to increase) the priority for outputting the specific image by the user In such a case, the priority of the specific image is set to the highest priority and the file name is added. Thus, the user can increase the priority order of the favorite images so that the favorite images are preferentially displayed.

(2) If the user is not instructed to increase the priority, a file name is assigned to the specific image so that the priority is the lowest among the non-specific images recorded on the memory card. Added. As a result, the user can record the images other than the favorite images at a lower priority, and can prevent the images other than the favorite images from being displayed preferentially.

-Third embodiment-
In the third embodiment, a user designates a priority order to be set for a captured image in advance, and a file based on a priority order specified in advance for the captured image every time shooting is performed. A method for adding a name will be described. In the third embodiment, the block diagram of the camera 100 shown in FIG. 1 and the file name change process shown in FIG. 4 are the same as those in the first embodiment, and a description thereof will be omitted.

  FIG. 7 is a diagram showing a specific example of the file name change process in the present embodiment. First, it is assumed that 10 image files with file names added are stored in the memory card as shown in FIG. 7A, and the file name list shown in FIG. It is assumed that the name information is read on the RAM. In addition, it is assumed that the priority is set in advance by the user so that the priority order of the captured image is always 5. That is, in the present embodiment, the file name “DSCN0005” is always added to the image file of the captured image.

  The user can set priority by operating the operation member 101. The priority order (for example, No. 5) input by the operation member 101 is stored in the RAM of the control device 104.

  At this time, when the user gives an instruction to capture an image and image data is input from the image sensor 103, the control device 104 generates an image file as described above. Then, the priority changing unit 104b identifies the captured image as a specific image, and writes the file name of the specific image as “DSCN0005” in the file information recorded on the RAM, as shown in FIG. 7B.

  As a result, as shown in FIG. 7B, since the file name of the specific image and the non-specific image whose file name is “DSCN0005” overlap, the priority changing unit 104b The file name is changed to “DSCN0006” by adding 1 to the numeric part. Further, since the file name of the non-specific image after the change overlaps with the file name of the non-specific image whose file name has been “DSCN0006” until now, the file name of the non-specific image is changed to “DSCN0007”. Thereafter, as shown in FIG. 7C, the priority order changing unit 104b sequentially adds 1 to the numerical part of the file name of the non-specific image until there is no duplication of the file name. Decrease the priority one by one.

  Thereafter, as shown in FIG. 7D, when a further image is taken, the priority changing unit 104b sets the file name of the image to “DSCN0005”. Then, as shown in FIG. 7E, similarly, 1 is added to the numeric part of the file name of the non-specific image whose file name is “DSCN0005” or later. As a result, the file name of the captured image can be set to a file name based on the priority set in advance by the user, and further, the file name of each file can be prevented from being duplicated.

  FIG. 8 is a flowchart illustrating processing of the camera 100 according to the third embodiment. The processing shown in FIG. 8 is executed by the control device 104 as a program that starts when shooting is instructed by the user. In FIG. 8, steps having the same processing contents as those in FIG. 3 described in the first embodiment and FIG. 6 described in the second embodiment are assigned the same step numbers and description thereof is omitted. The difference will be mainly described.

  In step S11, the captured image is specified as a specific image, the process proceeds to step S24, the priority order after the change of the specific image is set to a preset priority order, and the process proceeds to step S30.

  According to the third embodiment described above, the following effects can be obtained in addition to the functions and effects of the first embodiment. That is, the photographed image is specified as the specific image, and the file name as priority information is added to the specific image so that the priority for output of the specific image is the priority specified in advance by the user. . This makes it possible to always add a file name based on the priority order designated by the user to the latest photographed image.

-Modification-
The camera according to the above-described embodiment can be modified as follows.
(1) In the above-described first to third embodiments, the example in which the file name is used as the priority information indicating the priority when the image file is output has been described. In other words, the priority at the time of data output is expressed by the size of the number part constituting the file name. However, other information may be used as priority information. For example, priority information may be stored in the Exif data, and a number or alphabet representing the priority may be stored here.

(2) In the second embodiment, an example has been described in which when a user gives a priority order change instruction when shooting is performed, the highest priority order of the captured image is set. However, the priority may be set to any one of the second and subsequent priorities. At this time, which priority order is set may be specified in advance, or may be specified each time the user operates the operation member 101. The priority (for example, No. 5) input by the operation member 101 is recorded in the RAM of the control device 101. Then, the priority order changing unit 104b sets the priority order after the change of the specific image as the priority order stored in the RAM in step S21 of FIG.

(3) In the above-described first to third embodiments, the example in which the priority order can be set or changed for an image recorded on a memory card or a captured image has been described. However, the priority order of data other than images may be set or changed. For example, when the camera 100 has a moving image shooting function, it is possible to set or change the order of priority during moving image playback for moving images recorded on a memory card or captured moving image data. . Alternatively, when the camera 100 has a music playback function, the priority order during music playback may be set or changed for music data recorded on the memory card.

  Note that the present invention is not limited to the configurations in the above-described embodiments as long as the characteristic functions of the present invention are not impaired.
