  Hereinafter, processing when the digital camera 100 performs a shooting operation and transmits a shot image to the PC will be described.

  In this processing, it is assumed that the count-up information and the UUID management table shown in FIG. 3 are already recorded in the secondary storage device 107 of the digital camera 100.

  The UUID management table in FIG. 3 is a table for managing UUID 3002 and image file name 3003 in association with each other. The UUID management table includes a field Flag 3001 indicating a transfer completed flag. The field Flag of the UUID management table indicates whether an image has been transmitted. If it has been transmitted even once, a flag is attached.

  Hereinafter, the flow of processing will be described with reference to FIG. In this embodiment, it is assumed that the image file is once transmitted to the folder “C: ¥ Temp” in the HDD 2009 of the PC 101 and then copied to a storage medium accessible by the PC 101.

  FIG. 4 is a diagram for explaining processing until the digital camera captures a subject and adds a UUID to the resulting image file.

  First, in step S4001, the digital camera 100 performs a photographing operation in accordance with a user operation to photograph a subject.

  In step S4002, the digital camera 100 creates an image file from the obtained shooting data. At this time, the digital camera 100 applies, for example, IMG — 0001. A file name of jpg is given. This is a file name handled in the digital camera 100 (hereinafter, “camera file name”).

  In step S4003, the digital camera 100 creates a UUID from the individual number, shooting date / time, and count-up information of the digital camera 100. Specifically, a character string obtained by concatenating the unique number of the digital camera 100, the shooting date and time, and the count-up information value is defined as a UUID.

  In step S4004, the digital camera 100 updates the UUID management table. Specifically, the file name assigned to the image file in step S4002 and the UUID created in step S4003 are associated and registered in the UUID management table.

  Through the above processing, a UUID can be assigned to the image file.

  Next, a process in which the PC 101 receives the UUID and the image file to which the UUID has been added from the digital camera 100, assigns a new file name, and records it will be described. The flow of this processing is shown in FIG.

  First, in step S5001, the PC 101 receives a UUID and an image file from the digital camera 100. Although the UUID and image file transmission / reception processing will be described in detail later, reception of the image file and reception of the UUID may be performed by one communication or may be performed by a plurality of communication.

  In step S5002, the PC 101 changes the file name of the received image file. Specifically, a file name assigning process for assigning a file name to be handled in the “C: ¥ Temp” folder in the PC (hereinafter “PC file name”) to the image file is performed. The assigned new file name is used for performing various processes using UUID verification described later. The file name in the PC in this embodiment is a file name obtained by concatenating the UUID and the file name in the camera.

  In step S5003, the PC 101 stores the image file in the “C: ¥ Temp” folder.

  In step S5004, the PC 101 copies the image file in the folder “C: ¥ Temp” and saves it in the image storage destination folder existing in the HDD 2009. This image storage destination folder may be determined when the PC 101 receives an image file, or may be designated in advance on the digital camera 100 side.

  In step S5005, the PC 101 deletes the UUID portion from the file name of the image file saved in the image storage folder and displays the file name. That is, the UUID part is deleted from the file name in the PC, and the same file name as the file name in the camera is displayed.

  The above is the image reception / storage processing in the PC 101. In this embodiment, “C: ¥ Temp” is a hidden folder that cannot be accessed by a normal user, and the image storage destination folder is a folder that can be accessed by the user. As a result, the user can handle an image file with the same file name as the file name assigned by the digital camera 100 without being aware of the UUID in which numbers are enumerated.

  As described above, in this embodiment, the UUID is included in the PC file name. Since the PC file name is included in the directory entry, the UUID can be searched by searching the directory entry. Hereinafter, the structure of the directory entry will be described.

  The OS of the PC 101 has a function for managing files called a file system in a hierarchical structure, and a directory entry is used to realize this function. In the directory entry, information on all folders and files in a certain folder is recorded.

  The directory entry in the FAT (File Allocation Table) file system has the configuration shown in FIG. This configuration is used when the file name excluding the extension is 8 characters or less and the extension is 3 characters or less. The file name in this format is called an 8.3 format file name.

  FileName 6001 is a file name (up to 8 characters), and Extension 6002 is an extension (up to 3 characters). Attribute 6003 indicates a file attribute. Reserved 6004 indicates a reserved area. CreateTimeMs6005 indicates 10 milliseconds of creation time. CreateTime 6006 indicates the creation time, and CreateDate 6007 indicates the creation date and time.

  ClusterHighWord 6009 indicates the upper 16 bits of the leading cluster number used in FAT32. UpdateTime 6010 indicates the update time, and UpdateDate 6011 indicates the update date and time. CluSer 6012 indicates the lower 16 bits of the leading cluster number. FileSize 6013 is a file size. 0 for a directory.

  In the case of a file name longer than the 8.3 format file name, an LNF (Long File Name) directory entry in FIG. 7 is also used in addition to the directory entry in FIG.

  In one LNF directory entry in FIG. 7, a file name of up to 13 characters can be recorded in Unicode. If it exceeds 13 characters, an LNF directory entry is added and the file name is recorded.

  LNFSeqNumber 7001 indicates the order of file names. If 0x40 is added, this indicates that this LNF directory entry is an LNF directory entry indicating the end of the file name.

  Name 1st (7002) indicates the first 5 characters of 13 characters. Attribute 7003 contains a value (0x0f) indicating that it is an LNF directory entry. Reserved 7004 is a reservation. CheckCodeForShortName7005 is a check code for the 8.3 format file name.

  Name2nd (7006) contains 6th to 11th characters out of 13 characters. Cluster 7007 contains the value of the cluster to be used, but 0x0000 is always entered in the case of an LNF directory entry. Name3rd (7008) contains the 12th and 13th characters of 13 characters.

  For example, the file name in the PC is 10,000,000,000,000,000,000,000_IMG_0001. In the case of jpg, the directory entry is recorded as shown in FIG.

  SE is a directory entry when the file name is converted into an 8.3 file name, and information about the file such as the file size of this file is recorded. Here, 100,000-1. It is assumed that the file is converted to an 8.3 file name called JPG. In this example, four LNF directory entries are used.

  The file names are recorded in order from the LNF directory entry LE1, and finally recorded in the LNF directory entry LE4. In addition, after the file name is recorded by LE4, a value 0x0000 indicating the end of the file name is recorded. If there is a vacancy in Name1st, Name2nd, and Name3rd for recording file names, they are filled with 0xFFFF.

  However, when the number of characters in the file name is a multiple of 13, the value 0x0000 indicating the end of the file name is not used, and it is not necessary to fill with 0xFFFF.

  Hereinafter, an operation in which the PC 101 searches for image data having a specific UUID will be described.

  Here, in the “C: ¥ Temp” folder, the image file 10000000000000000000000000_IMG — 0001. Assume that jpg is saved.

  First, the PC 101 searches for a directory entry of “C: ¥ Temp”. The directory entry in which “10000000000000000000000000” exists is searched from the file name field of each directory entry in “C: ¥ Temp”. Since the file name field of the found directory entry is concatenated with the file name in the camera, the UUID portion of 10,000,000,000,000,000,000,000 is extracted therefrom.

  As described above, the PC 101 retrieves the UUID from the directory entry using the file system that is a function of the OS. That is, the PC 101 can search for an image file using the UUID as a search key without using a special database. As a result, it is possible to reduce the capacity and cost required for database implementation.

  In this embodiment, the connection between the PC 101 and the digital camera 100 may be a wired connection such as USB, or IEEE802. A wireless connection such as x may be used.

FIG. 9 is a flowchart showing a procedure of processing for transmitting an image file from the digital camera 100 to the PC 101, which is executed by the image processing system of FIG. On the left side of the dotted line is processing performed by the CPU 103 of the digital camera 100 in accordance with an input signal or a program. On the right side of the dotted line is processing performed by the CPU 2006 of the PC 101 in accordance with an input signal or a program. The same applies to other flowcharts.
This flow may be started automatically when it is detected that the connection between the digital camera 100 and the PC 101 has been established, or started when the user operates the operation member 108 to instruct transfer. Also good.

  In step S9001, the digital camera 100 refers to the UUID management table, acquires the UUID of the image file to be transferred, and transmits it to the PC 101. The image file to be transferred may be designated in advance by the user by operating the operation member 108, or all image files in the removable storage medium may be automatically transferred.

  In step S9002, the PC 101 receives the UUID transmitted from the digital camera 100 in step S9001.

  In step S9003, the directory entry of the folder “C: ¥ Temp” is referred to on the PC 101 to search for an image file having a file name including the received UUID.

  In step S9004, the PC 101 determines whether there is any UUID received in step S9002 that is not included in the directory entry of the image file in “C: ¥ Temp”. This is determined by checking the UUID to determine whether there is an image file that exists in the digital camera 100 but does not exist in the PC 101. If it is determined that there is something not included, the process advances to step S9005. If it is determined that there is nothing not included, that is, all the image files having the UUID received from the digital camera 100 exist in the PC 101, the process is terminated.

  In step S9005, the PC 101 transmits the UUID that does not match to the digital camera 100.

  In step S9006, the digital camera 100 receives a UUID from the PC 101.

  In step S9007, the digital camera 100 refers to the UUID management table, specifies an image file corresponding to the UUID received in step S9006, and transmits the image file to the PC 101.

  In step S9008, the PC 101 receives the image file transmitted by the digital camera 100, and ends this process. After the end of this process, the PC 101 assigns the file name shown in FIG.

  As described above, in this embodiment, the image file in the digital camera 100 and the image file in the PC 101 are collated using the UUID. Accordingly, it is possible to transmit only necessary data without transmitting an image file already existing in the PC 101 from the digital camera 100. Therefore, it is possible to speed up the process of transmitting from the digital camera 100 to the PC 101. Further, since the UUID is included in the file name in the PC, the UUID can be verified by searching the directory entry. This makes it possible to collate UUIDs without having a special database or the like, thereby reducing the cost of mounting.

  Next, write back processing from the PC 101 to the digital camera 100 will be described. The write back process in the present embodiment is a process for transmitting an image file from the PC 101 to the digital camera 100.

  FIG. 10 is a flowchart showing the procedure of the write-back process executed by the image processing system of FIG.

  Here, it is assumed that one of the image files stored in the HDD 2009 of the PC 101 is selected as a target to be written back to the digital camera 100 by the user operation. Assume that the in-camera file name of the image file is “IMG — 0001.jpg” and the UUID is 0x10000000000000000000000000000000. Therefore, the file name in the PC is “10000000000000000000000000000000_IMG — 0001.jpg”.

  First, in step S1001, the PC 101 accesses the folder “C: ¥ Temp” and searches for an image file that matches the file name at the end. In this example, a file whose file name ends with “IMG — 0001.jpg” is searched.

  In step S1002, the PC 101 acquires a UUID from the matched image file name. In this example, the acquired UUID is “0x10000000000000000000000000”.

  In step S1003, the PC 101 transmits the UUID acquired in step S1002 from the PC 101 to the digital camera 100.

  In step S1004, the digital camera 100 receives the UUID transmitted in step S1003.

  In step S1005, the digital camera 100 determines whether the received UUID exists in the UUID management table. If there is a UUID, this means that the same image file exists on the digital camera 100 side, and thus this processing ends. If there is no UUID, the process proceeds to step S1006. If there are a plurality of received UUIDs, and there is even one UUID that does not exist in the UUID management table, the process advances to step S1006.

  In step S <b> 1006, the digital camera 100 transmits the UUID that is determined not to exist in the UUID management table in step S <b> 1005 to the digital camera 100.

  In step S1007, the PC 101 receives the UUID transmitted from the digital camera 100.

  In step S1008, the PC 101 transmits the image file having the UUID received in step S1008 to the digital camera 100. In the example of this flow, the image file 10000000000000000000000000000000_IMG_0001. jpg is transmitted from the PC 101 to the digital camera 100.

  In step S <b> 1009, the digital camera 100 receives the image file transmitted from the PC 101.

  In step S1010, the digital camera 100 changes to delete the UUID portion from the file name of the received image file. This deletion process may be performed on the PC 101 side. That is, before the transmission processing in step S1008, the PC 101 may delete the UUID portion from the file name of the image file to be transmitted.

  In step S1011, the digital camera 100 records the image file name and UUID in the UUID management table in the digital camera 100, and ends this process. In this case, “0x10000000000000000000000000000000” is written in the field UUID, and “IMG — 0001.jpg” is written in the field Name.

  As described above, by using the UUID, it is possible to prevent an image file already existing in the digital camera 100 from being transmitted from among image files to be transmitted. Therefore, it is possible to speed up the process of transmitting to the digital camera 100.

  In general, since the capacity of the removable storage medium 111 of the digital camera 100 is smaller than the HDD 2009 of the PC 101, the PC 101 may transmit an image file with a reduced size in the write-back processing in the present embodiment.

  Next, a flow of processing for reprinting an image file printed in the past with reference to the print history will be described.

  It is assumed that the history management table shown in FIG. In the history management table, UUIDs of image files printed in the past are recorded.

  FIG. 12 is a flowchart showing a procedure of image file reprint processing executed by the image processing system of FIG. This flowchart is started when the user operates the operation member 2004 to instruct a reprint request.

  First, in step S1201, the PC 101 acquires a UUID from the history management table.

  In step S1202, the PC 101 searches for a directory entry for each image file name in the folder “C: ¥ Temp”, and acquires a UUID from the file name.

  In step S1203, the PC 101 determines whether the UUID acquired in step S1201 exists in the file name of the directory entry searched in step S1202. That is, it is determined whether an image file having a UUID existing in the history management list exists in the folder “C: ¥ Temp”. If it is determined that it exists, the process proceeds to step S1204. If it is determined that it does not exist, this process ends.

  In step S1204, the PC 101 instructs to print an image file having a UUID existing in the history management list. Specifically, an image file to be printed is read into a printing application and a printing instruction is given to a printer (not shown).

  If it is determined in step S1203 that there is no matching UUID, this process ends.

  As described above, by using the history of the image file that has been printed once, the user can print the printed image file again without searching for the image file.

  The history management table may manage the number of printed sheets in association with the UUID of the printed image file. In that case, the PC 101 performs the history management table update process after performing the process of step S1204. That is, the value of the number of printed image files is increased by the number of printed sheets.

  Also, by using the history management table, it is possible to set only image files that have never been printed. This can be realized by setting only image files having UUIDs not in the history management table as print targets.

  In the present embodiment, the use of the history for printing has been described. However, the history can be used when performing a process that has been performed before, not limited to printing. Needless to say, processing based on a reprocessing request can be performed even in cases other than printing, such as an image file attached to an e-mail. A history management table other than printing, such as a history of an image file attached to an e-mail, can be managed by a table different from the printing history management table.

  Next, processing for transmitting an image file to which the UUID is not added to the PC 101 on the digital camera 100 side will be described.

  Such a case may occur, for example, when an image photographed by a camera that does not have a function of creating a UUID, such as the digital camera 100 in the present embodiment, is stored in the removable storage medium 111.

  FIG. 13 is a flowchart showing a procedure of processing for transmitting an image file from the digital camera 100 to the PC 101, which is executed by the image processing system of FIG. In the following description, as an example, the image file “IMG — 0001.jpg” is to be transferred. It is assumed that no UUID is added to the image file “IMG — 0001.jpg”.

  First, in step S1301, the digital camera 100 determines whether or not a UUID is assigned to the image file to be transferred. If not, the process advances to step S1302. If it has been assigned, the process advances to step S1303, and a transfer process is performed according to the flow shown in FIG.

  In step S1302, the digital camera 100 determines that the image file IMG_0001. jpg and UUID are transmitted from the digital camera 100 to the PC 101.

  Here, since the UUID value is not set by the camera, a temporary UUID “0x00000000000000000000000000000000” is issued and transmitted to the PC 101. Note that the temporary UUID does not necessarily have the value described here.

  Next, in step S1304, the PC 101 receives the image file and temporary UUID transmitted from the digital camera 100.

  In step S <b> 1305, the PC 101 determines whether there is an image file whose file name starts with “00000000000000000000000000_IMG_0001” among the image files stored in the folder “C: ¥ Temp”. If it exists, the process advances to step S1306. If not, the process advances to step S1312.

  In step S1312, the PC 101 determines that the image file IMG_0001. The file name of jpg is “00000000000000000000000000000000_IMG — 0001.jpg”, stored in “C: ¥ Temp”, and the process is terminated.

  In step S1306, the PC 101 substitutes 0 for the variable N.

  In step S1307, the PC 101 compares the image file “00000000000000000000000000000000_IMG_0001.jpg” existing in the folder “C: ¥ Temp” with the received Exif header binary of “IMG — 0001.jpg”. The binary of the Exif header here is data such as shooting information included in the image file. For example, by comparing the shooting date and time included in the image file, it is possible to determine whether the image files have the same image data or the data whose file names just coincided with each other. If it is determined that the binaries are the same, the process proceeds to step S1311. If it is determined that the binaries are different, the process proceeds to step S1308.

  In step S1308, the PC 101 substitutes N + 1 for the variable N.

  In step S1309, the PC 101 determines whether an image file with the file name “IMG — 0001_N.jpg” exists in the folder “C: ¥ Temp”. For example, if N is 1, it is determined whether there is an image file whose file name is “IMG — 0001 — 1.jpg”. If it exists, the process advances to step S1310. If not, the process advances to step S1313.

  In step S1313, the PC 101 determines that the image file IMG_0001. The file name of jpg is set to “00000000000000000000000000000000_IMG — 0001_N.jpg”, stored in “C: ¥ Temp”, and the process is terminated.

  In step S1310, the PC 101 compares the file “00000000000000000000000000000000_IMG_0001_N.jpg” with the binary of the Exif header of the received “IMG_0001.jpg”. If so, the process advances to step S1311. If they are different, the process returns to step S1308, the value of N is incremented, and the process is repeated.

  In step S1311, the PC 101 discards the image file “IMG — 0001.jpg” received in step S1304 and its UUID, and the process ends.

  As described above, even when an image file without a UUID is transferred on the digital camera 100 side, the PC 101 does not receive and store an existing image file again.

  Next, a procedure for writing back an image file without a UUID from the PC 101 to the digital camera 100 will be described.

  FIG. 14 is a flowchart showing a procedure of processing for writing back an image file from the PC 101 to the digital camera 100, which is executed by the image processing system of FIG.

  Here, it is assumed that an image file with the in-camera file name “IMG — 0001.jpg” is designated as a transfer target by a user operation. This image file is transmitted from the digital camera 100 to the PC 101 by the process shown in FIG. 13, and the file name in the PC is “00000000000000000000000000_IMG — 0001.jpg”.

  First, in step S1401, the PC 101 accesses the folder “C: ¥ Temp” and searches for an image file that matches the end “IMG — 0001.jpg” of the file name of the image file to be transferred.

  In step S1402, the PC 101 acquires a UUID from the image file name obtained as a result of the search in step S1401. Here, 0x00000000000000000000000000000000 is acquired as the UUID. This indicates that no UUID is assigned on the digital camera 100 side.

  In step S1403, the PC 101 transmits to the digital camera 100 the character string “IMG — 0001.jpg” indicating the UUID acquired in step S1402 and the file name in the camera.

In step S <b> 1404, the digital camera 100 receives the character string “IMG — 0001.jpg” indicating the file name in the camera and the UUID transmitted from the PC 101.
In step S1405, the digital camera 100 refers to the UUID management table and determines whether or not the received character string “IMG — 0001.jpg” exists. If it exists, it is determined that the image file to be transferred already exists, and this processing is terminated. If not, the process advances to step S1406. If a character string has been received, if any one of them is not present in the UUID management table, the process advances to step S1406.

  In step S1406, the digital camera 100 transmits to the PC 101 a character string indicating a file name in the camera that does not exist in the UUID management table.

  In step S <b> 1407, the PC 101 receives a character string indicating the in-camera file name transmitted from the digital camera 100.

  In step S1408, the PC 101 transmits an image file having a character string indicating the received in-camera file name to the digital camera 100. In this example, an image file having a file name “000000000000000000000000000000_IMG — 0001.jpg” is transmitted to the digital camera 100.

  In step S1409, the digital camera 100 receives the image file transmitted from the PC 101.

  In step S1410, the digital camera 100 deletes the UUID portion from the file name of the received image file. As a result, the file name is “IMG — 0001.jpg”. This process may be performed by the PC 101. In that case, the PC 101 deletes the UUID portion before transmission in step S1408.

  In step S1411, the digital camera 100 records the image file name and UUID in the UUID management table, and ends this process.

  In this case, “0x00000000000000000000000000000000” is written in the field UUID, and “IMG — 0001.jpg” is written in the field Name.

  In step S1412, the digital camera 100 attaches a transferred flag to the field flag of the UUID management table, and ends this process.

  As described above, an image file without a UUID can be written back to the digital camera 100. In addition, since the transferred flag is added to the UUID management table of the digital camera 100 after writing back to the digital camera 100, it is possible to avoid sending the same image file again when sending the image file to the PC 101.

  Next, a method for indicating the file name of the image file stored in the PC 101 to the user of the PC 101 will be described.

  Here, it is assumed that an image file is stored in the folder “C: ¥ Temp” of the PC 101 as shown in FIG. These files are stored as temporary files.

  When the image file name is displayed on the display member 2001 of the PC 101, the file name obtained by deleting the UUID portion from the file name in the PC is displayed.

  Consider the case where the image file 1504 is displayed among the file names shown in FIG. In this case, the file name is “222223333344445555666677778888889999_IMG — 0002.jpg”. Therefore, the PC 101 deletes the UUID part “2222233343445555556667777788889999” ”and“ _ ”and displays“ IMG — 0002.jpg ”.

  Similarly, when the file name of the image file 1501 is shown to the user, “IMG — 0001.jpg” is displayed. When displaying the file names of the image files 1505 and 1506, “IMG — 0003.jpg” and “IMG — 0004.jpg” are displayed, respectively.

  As a result of this processing, the file name shown to the user on the PC 101 becomes the file name given when the digital camera 100 takes a picture, that is, the file name in the camera.

  Consider the case where the file name of an image file 1502 is displayed in FIG. In this case, the file name is “000000000000000000000000000000_IMG — 0001 — 1.jpg”. Therefore, the PC 101 deletes the UUID portion and the counter portion before the extension, that is, “_1”. As a result, “IMG — 0001.jpg” is displayed. Similarly, when displaying the file name of the image file 1503, “IMG — 0001.jpg” is displayed.

  As a result of this processing, any file name shown to the user on the PC 101 is a file name given when the digital camera 100 takes a picture.

  As described above, in the present embodiment, when the PC 101 displays the image file name, the UUID portion is deleted, and the file name displayed when the digital camera 100 captures the image is displayed. As a result, a familiar image file name is displayed and the user can easily recognize the image file.
