A CPU 10 displays a clustering range selection table 24 on a display unit 15 (S203), and performs clustering based on a logical product of a shooting period name 23b and a shooting area name 23 according to a condition selected by a user. This is performed (S206). Further, the CPU 10 creates a clustering name based on the shooting period name 23b and the shooting area name 23c (S207). As a result, the user can cluster the image files 13 quickly and accurately using the shooting period names 23b and the shooting area names 23c with high reliability. Further, the user can easily search, slide show, copy, and transmit the image file 13 by referring to a clustering name with good visibility. [Selection] Figure 8

Description

  When searching for a plurality of image files by clustering, the present invention creates a shooting period name and a shooting region name, and automatically clusters the image files based on the logical product of these two names, so that the user can remember. The present invention relates to an image file clustering system and an image file clustering program for generating an easy, objectively reliable and accurate clustering name.

  In recent years, various portable electronic devices such as a mobile phone, a digital camera, a portable game machine, a notebook computer, a tablet personal computer, and a smartphone have a built-in camera image sensor, and the captured image file is stored in an internal memory. In addition, data display devices such as stationary personal computers, televisions, or projectors, and semiconductor storage devices, HDD storage devices, optical disk storage devices, or storage servers can send, receive, upload, download, copy, or move large amounts of image files. Is accumulated. A plurality of image files stored in these devices are clustered based on conditions such as date and time and event names. The user can easily search and reproduce the image file by performing clustering. However, if the user clusters image files based only on the date and time, the number of image files cannot be effectively narrowed down, and a desired image file cannot be quickly searched. Therefore, a clustering method that can narrow down the number of image files by the logical product of two or more cluster names has been proposed.

  For example, the directory name of the image file is the first cluster name candidate, the creation period of the image file is the second cluster name candidate, the character string input by the user is the third cluster name candidate, and among these three cluster name candidates, A method of efficiently clustering image files using any two logical products is known (see Patent Document 1).

  However, the technique disclosed in Patent Document 1 has a problem that it is difficult for a user to handle a directory name that is a first cluster name candidate because it is usually a DCF name. Moreover, since the DCF name is composed of 8 uppercase letters and numbers, there is a problem that visibility is poor. In addition, the shooting date and time that is the second cluster name candidate is not completely accurate. Furthermore, the third cluster candidate is usually an event name input by the user, and in addition to the complexity of input, the shooting period and the period in which the event was performed may not match, so accuracy, objectiveness There was a problem of lack of reliability and certainty.

  FIG. 11 shows an example of a display screen when clustering conventional image files. In FIG. 11, a display window 100 displayed on the monitor of the personal computer has a menu window 101 for displaying menus such as “copy”, “slide show”, “print”, “edit”, and “send” at the top thereof. Is provided. On the left side of the display screen 100, a clustering type column 102 indicating the type of clustering based on “folder”, “shooting date”, and “place name” is displayed, and a clustering hierarchy column 103 is displayed below the clustering type column 103. On the right side of the display screen 100, a thumbnail image display screen 105 for displaying the thumbnail image 104 is displayed. In response to the user selecting “folder” displayed in the clustering type column 102, the clustering hierarchy column 103 displays a list of DCF (Design rule for Camera File system) directory names such as “100 FUJI”. . The directory name is synonymous with the folder name. The thumbnail image display screen 105 displays six thumbnail images 104 held in the “101NIKON” folder. Since the folder name and file name according to the DCF standard are composed of a character string of 8 alphanumeric uppercase characters, the visibility is extremely poor for the user. Further, there is a problem that these character strings are meaningless to the user.

  12A and 12B show an example of a conventional clustering result. FIG. 12A shows an example in which image files are clustered according to shooting dates, and FIG. 12B shows an example in which image files are clustered by shooting location names. Unlike clustering by folders shown in FIG. 11, FIGS. 12 (a) and 12 (b) both show a clustered state by virtual folders. FIG. 12A shows a state in which the image file is clustered by a single item called shooting date, and FIG. 12B shows a state in which the image file is clustered by a single item called place name. When clustering is performed using only the shooting date and place name instead of the actual folder, the range of narrowing becomes wider, and the number of clustered image files increases. As a result, the user has to search the image file with reference to the thumbnail image 104.

  Also, depending on the location where the image file is taken, the GPS information attached to the image file may hold inaccurate information. Also, when an image file was shot overseas, the time difference could not be reflected on the shooting date. Since the GPS information or the shooting date is inaccurate, there is a problem that the user cannot accurately cluster the image file. Furthermore, the system using the virtual folder has a problem that it is difficult to handle the folder when the folder is directly transmitted or when the folder is transmitted via a communication line.

  Hereinafter, an image file clustering system 1 (abbreviated as system) according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a system 1 according to the present embodiment. The system 1 includes a portable electronic device 2, an external storage device 3, a router 4, the Internet 5, and a GPS information conversion device 6. The portable electronic device 2 is, for example, a digital camera having a camera imaging function, a smartphone, a notebook computer, a tablet computer, or a portable game device. The external storage device 3 is, for example, a storage device built in a data display device such as a semiconductor storage device, HDD storage device, optical disk storage device, or storage server, or a stationary personal computer, a television, or a projector.

  The portable electronic device 2 and the router 4 include wireless transmission / reception units 7 and 8, respectively, and transmit / receive data via a wireless signal 9. The radio signal 9 is a mobile phone network such as 3G (3rd Generation) or a Wi-Fi radio signal. The router 4 and the GPS information conversion device 6 are connected to the Internet 5. Note that the GPS information conversion device 6 may not be configured outside the portable electronic device 2 but may be configured inside the portable electronic device 2.

  The portable electronic device 2 includes a wireless transmission / reception unit 7, a CPU 10 (control unit) that controls the portable electronic device 2, a storage unit 12 that stores a control program 11 that controls the CPU 10, and a data storage unit that stores an image file 13. 14, an image file 13 and a display unit 15 for displaying characters, an external connection terminal 16 to which the external storage device 3 is connected, an input unit 17 for inputting characters or operation commands by a user, and a camera imaging unit 18 A GPS information detection unit 19 that measures and detects GPS information 28b indicating the position of the portable electronic device 2 and a memory card control unit 21 that controls a removable memory card 20, which are connected to the bus 22. ing. The input unit 17 is, for example, a mouse, a keyboard, or a touch panel.

  The data storage unit 14 stores an image file 13, a TPO (Time Place Occlusion) database 23, a clustering range selection table 24, a world time difference map 25, a current location map 26 (map), and an event setting table 27. To do. The image file 13 generated by the camera imaging unit 18 is stored in the data storage unit 14. Usually, the image file 13 is formatted in accordance with the DCF standard (camera file system standard) and the Exif standard (digital still camera image file format standard). As a result, the data storage unit 14 stores the plurality of image files 13 in a clustered state based on the DCF directory name and the DCF file name based on the DCF standard.

  An imaging device such as a digital camera or a smartphone automatically names an alphanumeric character string consisting of 8 characters as a DCF directory name and a DCF file name. The DCF directory name and the DCF file name are character strings that have poor visibility for the user and are difficult to remember. The data format of the image file 13 is the JPEG format, and the image file 13 holds Exif attached information 28 (attached information) based on the Exif standard. The Exif attached information 28 is information relating to shooting conditions and shooting equipment, and holds at least a shooting date 28a and GPS information 28b. The shooting date / time 28a is, for example, the date / time in year, month, day, hour, minute, and second when the image file 13 is shot by the camera imaging unit 18. The GPS information 28b is information indicating the position detected by the GPS information detection unit 19 when the image file 13 is captured by the camera imaging unit 18, for example. The information indicating the position is, for example, latitude and longitude.

  The memory card 20 stores an image file 13 photographed with another electronic device. The memory card control unit 21 reads the image file 13 stored in the memory card 20. Similar to the other image files 13, the image file 13 stored in the memory card 20 is formatted according to the DCF standard and the Exif standard, and holds Exif attached information 28.

  The shooting date and time 28a is represented by a string of numbers according to the Exif standard. The Exif standard numeric string is expressed in a format of “YYYY: MM: DD HH: MM: SS” using a colon for year, month, day, hour, minute, and second. The image file 13 photographed by a digital camera that does not include the GPS information detection unit 19 has Exif attached information 28, but the GPS information 28b contains no information or Null. . When the GPS information 28b does not hold position information, the user cannot know where the image file 13 was shot. Also, when the user travels to an area with a time difference, the date and time set in the digital camera must be corrected to the local standard time. However, if the user captures the image file 13 without correcting the date and time of the digital camera to the local standard time, the shooting date and time 28a holds a date and time different from the standard time of the shooting location.

  In this case, the image file 13 holds an incorrect date and time that does not reflect the time difference as the shooting date and time 28a. Under such circumstances, the image date / time 28a or the GPS information 28b held by the image file 13 taken in the past or the image file 13 received from another person often holds inaccurate information. The system 1 has a function of correcting the information of the shooting date / time 28a or the GPS information 28b to a correct value in order to accurately cluster the image file 13.

  The TPO database 23 holds information generated based on the shooting date and time 28a and the GPS information 28b, and is used for clustering the image file 13. The clustering range selection table 24 holds information regarding the ranges of the shooting date and time 28a and the GPS information 28b input via the input unit 17. The world time difference map 25 is a world map in which regions all over the world are associated with the standard time of each region. The current location map 26 is a map showing the vicinity of the position of the portable electronic device 2 detected by the GPS information detection unit 19. The event setting table 27 holds a schedule set by the user.

FIG. 2 shows the configuration of the TPO database 23. The TPO database 23 is
An image file name 23a, a shooting period name 23b, a shooting area name 23c, an event name 23d, and a home district name 23e are held. The image file name 23a holds an image file name 23a for specifying the image file 13. The shooting period name 23b holds the period of the shooting date and time when the image file 13 was shot. The shooting area name 23c holds the area name where the image file 13 was shot. The event name 23d holds a character string arbitrarily given by the user to the image file 13 and the name of the event. The event name 23d is, for example, a character string “birthday party” given to the image file 13 taken at an event called birthday party. The home district name 23e holds the name of a region where the user usually uses a photographing device such as a digital camera. Usually, the home district name 23e is an area where the user lives, and holds a country, a prefecture, a city, and the like.

  The image file name 23a may hold a value that can identify the image file 13. Therefore, the TPO database 23 may hold an arbitrary character string uniquely given to the image file 13 as the image file name 23a instead of the image file name 23a according to the DCF standard. This arbitrary character string is the updated image file name 23a, and may be held in the data storage unit 14 or the Exif attached information 28 as the history name of the image file 13. The shooting period name 23b and the shooting area name 23c are information generated based on accurate shooting date and time 28a and GPS information 28b. If there is a time difference between the area where the user lives and the shooting location of the image file 13, the TPO database 23 holds a value reflecting the time difference as the shooting period name 23b. Further, the TPO database 23 holds the name of the area where the image file 13 was actually shot as the shooting area name 23c for the image file 13 shot with a digital camera that does not include the GPS information detection unit 19.

  3A and 3B show an example of the clustering screen 29. FIG. 3A shows a clustering screen 29 in which the home district is designated by the user, and FIG. 3B shows a clustering screen 29 in which the shooting location is designated by the user. With reference to FIG. 3A, the clustering screen 29 displays a plurality of buttons 30 that cause the system 1 to execute various operations on the upper stage of the clustering screen 29. A folder window 31 for displaying a folder name is displayed at the lower left end of the plurality of buttons 30, and an image file window 32 for displaying an image file 13 is displayed on the right side of the folder window 31. On the right side of the window 32, a map window 33 for displaying the world time difference map 25 is displayed.

  In response to the user selecting a folder that holds the image file 13, the folder window 31 displays the folder name of the selected folder. The image file window 32 displays the thumbnail image and the image file name 23a of the image file 13 held by the folder displayed in the folder window 31. The map window 33 displays the world time difference map 25 in response to the folder being selected. The world time difference map 25 is a world map that distinguishes and displays areas with the same standard time by dotted lines and colors.

  The user selects a point corresponding to the home district from the world time difference map 25 via the input unit 17. The CPU 10 stores the area name previously associated with the selected point in the TPO database 23 as the home area name 23e. As a result, the system 1 can recognize the home district as a character string.

  With reference to FIG. 3B, the clustering screen 29 displays the current location map 26 in the map window 33. The CPU 10 identifies one of the plurality of image files 13 displayed in the image file window 32. The CPU 10 refers to the GPS information 28b of the identified image file 13. When the GPS information 28b does not hold any information or holds Null, the CPU 10 displays the current location map 26 on the map window 33. The current location map 26 holds GPS information 28b corresponding to points on the map.

  At this time, since the GPS information 28b does not hold information regarding the accurate shooting location, the user selects a point corresponding to the shooting location of the image file 13 from the current location map 26. The user recalls the shooting location of the image file 13 by referring to the thumbnail image of the image file 13 and selects a point from the current location map 26. The current location map 26 is configured to be able to move places such as countries and regions and change the enlargement rate and reduction rate according to the user's preference.

  The CPU 10 acquires GPS information 28 b corresponding to the point on the selected current location map 26. The CPU 10 transmits the acquired GPS information 28 b to the GPS information conversion device 7 via the wireless transmission / reception unit 7. The GPS information conversion device 7 converts the received GPS information into an area name and transmits it to the portable electronic device 2. The CPU 10 stores the received area name in the TPO database 23 as the shooting area name 23c. As a result, the system 1 can recognize the exact shooting location of the image file 13 by the character string.

  Next, clustering processing of the image file 13 will be described. FIG. 4 shows a process flow for creating the TPO database 23. Creation of the TPO database 23 is performed as pre-processing for clustering processing. In response to the user selecting the folder or image file 13 to be clustered, the CPU 10 displays the world time difference map 25 in the map window 33 of the clustering screen 29 (S101). One point of the world time difference map 25 is selected by the user as a home district (S102). The CPU 10 stores the area name associated with the point selected as the home area in the home area name 23e of the TPO database 23 (S103).

  The CPU 10 specifies one image file 13 as a clustering target. The image file 13 may be automatically specified by the CPU 10 or specified by the user via the input unit 17. The CPU 10 checks whether or not the shooting date 28a of the specified image file 13 is within a preset range (S104). The preset range is a range from January 1, 1990 to December 31, 2037. Since digital still cameras have become popular since January 1, 1990, it is highly possible that the shooting date 28a of the image file 13 generated before January 1, 1990 is inaccurate. In addition, after 2038, electronic devices such as computers may malfunction due to UNIX and C language specifications.

  Therefore, the system 1 considers that the shooting date 28a of the image file 13 generated after January 1, 2038 is inaccurate. In step S104, when the shooting date / time 28a is within the range from January 1, 1990 to December 31, 2037, the CPU 10 determines that the value of the shooting date / time 28a is correct (Yes in S104). The CPU 10 stores the shooting date / time 28a determined to hold the correct value in the TPO database 23 as the shooting period name 23b (S106). At this time, the shooting date and time 28a is held in the shooting period name 23b in a format using characters or symbols indicating year, month, day, hour, minute, and second.

  In step S104, the CPU 10 determines that the value of the shooting date / time 28a is inaccurate when the shooting date / time 28a of the image file 13 corresponds to before January 1, 1990, or after January 1, 2038. (No in S104). Next, the CPU 10 causes the display unit 15 to display a screen that prompts the user to correct the shooting date 28a. When the value of the shooting date / time 28a is input by the user via the input unit 17 (S105), the CPU 10 stores the input shooting date / time 28a in the shooting period name 23b of the TPO database 23 (S106). . Further, the CPU 10 corrects the value of the photographing date 28a to the inputted photographing date 28a. Thereby, the TPO database 23 can hold the accurate shooting date and time 28a as the shooting period name 23b.

  Next, the CPU 10 checks whether the GPS information 28b of the identified image file 13 holds no information or Null (S107). When the GPS information 28b holds no information or when the GPS information 28b holds Null, the CPU 10 determines that the GPS information 28b does not hold the correct position information (Yes in S107). Next, the CPU 10 displays the current location map 26 in the map window 33 on the clustering screen 29 (S108). When the captured point of the image file 13 is selected from the current location map 26 via the input unit 17 (S109), the CPU 10 transmits the GPS information 28b of the selected point to the GPS information conversion device 6 ( S110).

  The GPS information conversion device 6 converts the received GPS information 28b into a region name, and transmits this region name to the portable electronic device 2 (S111). At this time, the GPS information conversion device 6 describes the area name in a form that is subdivided into a country name, a prefecture name, a municipality name, a district name, and a street name. When receiving the area name (S112), the CPU 10 stores the received area name in the TPO database 23 as the shooting area name 23c (S113). The shooting area name 23c holds the area name in a format that can be divided into a country name, a prefecture name, a municipality name, a district name, and a street name. Thereby, the shooting area name 23c can hold the exact area name where the image file 13 was shot. In step S107, when the GPS information 28b holds information that is not Null, the CPU 10 determines that the GPS information 28b holds correct position information (No in S107). Next, the CPU 10 executes the processing from step S110 to step S113, thereby causing the TPO database 23 to hold the area name as the shooting area name 23c.

  Next, the CPU 10 refers to the TPO database 23 and compares the shooting area name 23c of the identified image file 13 with the home area name 24e (S114). When the shooting area name 23c and the home district name 24e are different (No in S114), the CPU 10 determines that there is a time difference between the shooting location of the image file 13 and the home district. The situation where there is a time difference between the shooting location and the home district means that the user has taken the image file 13 in an area where the standard time is different from the home district without correcting the date and time of the electronic device such as a digital camera. To do. The CPU 10 calculates the shooting date 28a reflecting the time difference between the home district and the area name, and corrects the shooting date 28a (S115). The CPU 10 stores the corrected shooting date 28a in the TPO database 23 as a shooting period name 23b (S116). Thereby, the shooting period name 23b becomes the shooting date 28a based on the standard time of the shooting location.

  In step S114, when the shooting area name 23c matches the home district name 24e (Yes in S114), the CPU 10 determines that there is no time difference between the place where the image file 13 was shot and the home district, The process of step S116 is executed. Next, the CPU 10 confirms whether or not there is an image file 13 to be clustered that has not been subjected to the processing from step S102 to step S116 (S117). When there is an image file 13 for which the processing from step S102 to step S116 has not been executed (Yes in S117), the CPU 10 executes the processing of step S102. On the other hand, when the processing from S102 to S116 is executed for all the image files 13 (No in S117), the CPU 10 ends the processing for creating the TPO database 23.

  Next, the clustering range selection table 24 displayed on the display unit 15 will be described. FIG. 5 shows the configuration of the clustering range selection table 24. The clustering range selection table 24 is displayed on the display unit 15 because a condition for clustering the image file 13 is input. The clustering range selection table 24 includes a shooting period range window 34, a shooting area range window 35, and a notation name format selection window 36. The shooting period range window 34 is used to determine the period of the shooting date 28a of the image file 13. The user can cluster the image files 13 photographed at a desired time by selecting a range of the photographing date and time 28a of the image file 13 from the photographing period range window 34. In addition to year, month, day, hour, minute, second, year, month, day, hour, minute, year, month, day, hour, minute, second, year, month, day, hour, minute, second, or any A period is configured to be selected. Usually, the user clusters the image file 13 by “year” having a long period of the shooting date and time 28a. “Month”, “day”, and the like are shorter in the shooting date and time 28a than “year”. In FIG. 5, “year” is selected for the shooting period range window 34.

  The shooting area range window 35 is used to determine the area range in which the image file 13 was shot. The user can cluster the image files 13 photographed in the desired region by selecting the region range where the desired image file 13 was photographed from the photographing region range window 35. The shooting area range window 35 is configured to select a country, a prefecture, a municipality, a district, a street address, or all from a country to a street address. In FIG. 5, “country” is selected for the shooting area range window 35.

  The notation name format selection window 36 is used to select a format for displaying the shooting period name 23b and a format for displaying the shooting area name 23c. The notation name format selection window 36 includes a shooting period name format window 36a and a shooting area name format window 36b. The user can determine the display format of the shooting period name 23b and the shooting area name 23c by selecting the display format from the shooting period name format window 36a and the shooting area name format window 36b. The shooting period name format window 36a is configured so that, for example, the year can be selected from the year, the year, the Japanese calendar, the combination of the year and the Japanese calendar, or a display format using a hyphen. For example, the year is "2013", the year is "2013", the Japanese calendar is "2013", the combined writing is "2013 (2013)", and the hyphen is "2013". is there.

  The shooting area name format window 36b is configured to select, for example, a format for displaying all of a prefecture name, a prefecture name, or a country to an address. For example, the prefecture name is “Japan Nara Prefecture”, the prefecture name is “Japan”, and all (sequential names) are “Aoyamadai 1-1, Ikoma City, Nara Prefecture, Japan”.

  In the system 1, the image file 13 is preferably clustered in two layers. For example, in the shooting period range window 34, the user clusters the image file 13 by “year”, which means a period from the beginning of the year to the end of the year, as the first hierarchy. Next, the user clusters the image file 13 as “second month” with “month” meaning from the beginning of the month to the end of the month. Further, the user searches the desired image file 13 quickly and easily by clustering the image file 13 clustered by “month” with the logical product of the area ranges selected in the shooting area range window 35. It becomes possible.

  FIG. 6 shows an example of the clustering screen 29. When the “clustering” button is pressed from the buttons 30, the clustering screen 29 displays a hierarchical clustering window 37 instead of the map window 33. In the upper part of the hierarchical clustering window 37, a “first hierarchy” button 38 and a “second hierarchy” button 39 for clustering the image file 13 in two stages and a character string “notation name format” are displayed. Is done. A shooting period range window 34, a shooting area range window 35, and a notation name format selection window 36 are displayed below the "first hierarchy" button 38, the "second hierarchy" button 39, and the character string "notation name format". The

  After pressing the “first layer” button 38, the user selects an arbitrary item from each of the shooting period range window 34, the shooting area range window 35, and the notation name format selection window 36. The CPU 10 refers to the shooting period name 23b and the shooting area name 23c in the TPO database 23, and specifies the image file 13 corresponding to the item selected in the shooting period range window 34 and the shooting area range window 35. The CPU 10 refers to the TPO database 23 and acquires the shooting period name 23b and the shooting area name 23c corresponding to the shooting period and shooting area selected in the shooting period range window 34 and the shooting area range window 35. The CPU 10 creates the first hierarchical clustering by the logical product of the acquired shooting period name 23b and the shooting area name 23c. When creating the first hierarchical clustering, the CPU 10 creates a first hierarchical clustering name 40 (clustering name) that combines the shooting period name 23b and the shooting area name 23c. In the first hierarchical clustering name 40, for example, “2011 Japan”, the shooting period and the shooting area are continuously displayed. Further, the clustering name 40 may display the shooting period and shooting area in a form using the symbol “+”, such as “2011 + Japan”.

  The user presses the “second layer” button 39 after pressing the “first layer” button 38. Next, the user selects an arbitrary item from each of the shooting period range window 34, the shooting area range window 35, and the notation name format selection window 36. The CPU 10 refers to the TPO database 23 and creates the second hierarchical clustering based on the shooting period and shooting area selected in the shooting period range window 34 and the shooting area range window 35. Further, the CPU 10 creates the second hierarchy clustering name 41 (clustering name) in a format corresponding to the item selected in the notation name format selection window 36. The first hierarchical clustering name 40 and the second hierarchical clustering name 41 are displayed in the folder window 31. The image clustering name 42 (clustering name) created as the file name of the image file 13 is displayed in the image file window 32 together with the thumbnail image in the image file window 32. The CPU 10 may store the created image clustering name 42 in the TPO database 23 as the image file name 23 a according to the setting of the system 1.

  The user can easily execute various functions such as copying, slide show, printing, and transmission of the image file 13 by operating the button 30. For example, when the user selects “May 5 Nara” as the second hierarchical clustering name 41 displayed in the folder window 31 and then presses the “Copy” button 30, the CPU 10 The image file 13 corresponding to the two-tier clustering name 41 is copied to the external storage device 3. When the user selects the second hierarchical clustering name 41 and then presses the “slide show” button 30, the CPU 10 displays the image file 13 corresponding to the second hierarchical clustering name 41 on the display unit 15 as a slide show. Play in mode.

  Next, the logical product executed in the clustering process will be described. FIG. 7 shows an example of logical product and clustering name. In FIG. 7, A indicates a set of image files 13 corresponding to the conditions selected in the shooting period range window 34, and B indicates a set of image files 13 corresponding to the conditions selected in the shooting area range window 35. Show. A * B is a logical product of A and B, and indicates a set of image files 13 that satisfy both the conditions of A and B. The CPU 10 refers to the TPO database 23 and clusters the image file 13 corresponding to A * B, which is the logical product of A and B.

  The first hierarchical clustering name 40 will be described by taking the first hierarchical clustering as an example. When the set of A is the image file 13 whose shooting period name 23b is “2011” and the set of B is the image file 13 whose shooting region name 23c is “Japan”, the first layer clustering name 40 is, for example, , “2011 Japan”, “2011 + Japan”, “2011 * Japan”. Similarly, in the case of the second hierarchical clustering, the second hierarchical clustering name 41 is expressed as, for example, “May 5 Nara”, “May 5 + Nara”, “May 5 * Nara”. In the second hierarchical clustering name 41, for example, “2011” and “Japan” may be simultaneously displayed at distant positions on the display unit 15. Further, the first layer clustering name 40 and the second layer clustering name 41 may be virtual folder names or virtual file names instead of actual folder names or file names related to the image file 13.

  Next, clustering processing by hierarchization will be described. FIG. 8 shows a flow of clustering processing. The CPU 10 displays the clustering screen 29 on the display unit 15 (S201). The clustering screen 29 displays a hierarchy clustering window 37 having a “first hierarchy” button 38 and a “second hierarchy” button 39. In response to the user pressing the “first hierarchy” button 38 (S202), the CPU 10 adds a shooting period range window 34, a shooting area range window 35, and a notation name format selection window 36 to the hierarchy clustering window 37. Is displayed (S203).

  When the user selects an item in each of the shooting period range window 34, the shooting area range window 35, and the notation name format selection window 36 (S204), the CPU 10 captures the shooting period name 23b and the shooting area name in the TPO database 23. 23c is referred to (S205). The CPU 10 performs the first hierarchical clustering based on the items selected in the shooting period range window 34 and the shooting area range window 35 and the shooting period name 23b and the shooting area name 23c (S206). The CPU 10 creates the first hierarchical clustering name 40 based on the shooting period name 23b and the shooting area name 23c (S207).

  In response to the user pressing the “second hierarchy” button 39 (S208), the CPU 10 newly adds a shooting period range window 34, a shooting area range window 35, and a notation name format selection to the hierarchy clustering window 37. The window 36 is displayed (S209). When the user selects an item in each of the shooting period range window 34, the shooting area range window 35, and the notation name format selection window 36 (S210), the CPU 10 captures the shooting period name 23b and the shooting area name in the TPO database 23. 23c is referred to (S211). The CPU 10 performs second layer clustering based on the items selected in the shooting period range window 34 and the shooting area range window 35, and the shooting period name 23b and the shooting area name 23c (S212).

  Next, the CPU 10 creates a second hierarchical clustering name 41 based on the shooting period name 23b and the shooting area name 23c (S213). The CPU 10 hierarchically displays the first hierarchical clustering name 40 and the second hierarchical clustering name 41 in the folder window 31 (S214). Further, the CPU 10 creates the image clustering name 42 and displays it on the image file window 32 together with the thumbnail image of the image file 13 (S215), and ends the clustering process.

  Thus, the folder window 31 can present the clustering state with high visibility to the user by displaying the first hierarchical clustering name 40 and the second hierarchical clustering name 41 in a hierarchical manner. In addition, since the system 1 holds the TPO database 23, the clustering name in which the shooting period name 23b and the shooting area name 23c are accurately and objectively reliable can be displayed. It is possible to easily recognize the status of clustering. Thereby, the user can search for the desired image file 13 quickly. Clustering based on the shooting period name 23b and the shooting area name 23c can adjust the clustering range according to the purpose. Thereby, in order to identify the image file 13 simply, the user does not need a troublesome operation of individually inputting a character string such as the event name 23d. Even if the shooting period names 23c are the same, the image file 13 can be clustered by changing the shooting region name 23c. Furthermore, by using the TPO database 23, the system 1 can correct the shooting period name 23b when the shooting period name 23b is inaccurate due to the time difference.

  Next, a method for searching for an image file 13 and a folder that holds the image file 13 will be described. FIG. 9 shows an example of the clustering screen 29 for search. The search clustering screen 29 includes a search window 43 for inputting a character string by the user. When the “search” button 30 is pressed by the user on the clustering screen 29 shown in FIG. 6, the CPU 10 displays a search window 43 on the clustering screen 29 instead of the “search” button 30. The user can search for a desired image file 13 or folder by inputting a character string into the search window 43.

  The character string input to the search window 43 is a part or all of the shooting period name 23b, the shooting area name 23c, and the event name 23d. For example, when a part of a character string is input to the search window 43, the CPU 10 displays a menu of a plurality of candidates in the search window 43 by indexing a place name association dictionary associated with preset place names. For example, when “East” is input to the search window 43, the CPU 10 associates “Tokyo”, “Higashimurayama”, and “Higashi Ikoma”, which are associated with place names, and displays a plurality of candidates in a menu on the search window 43. . The user can easily and quickly input the entire character string into the search window 43 by selecting a desired word from a plurality of candidates, and can search the image file 13 with an accurate area name.

  Further, when a word related to the season or time such as “spring”, “autumn”, “dusk”, “morning”, or “daytime” is input to the search window 43, the CPU 10 sets the preset date and time, season and time. Index the dictionary about. For example, when words such as “spring”, “autumn”, “dusk”, “morning”, or “daytime” are input to the search window 43, the CPU 10 determines a date and time range based on a preset rule. The image file 13 is searched based on the determined date and time range. As described above, the system 1 includes various dictionaries in addition to the search window 43, so that the user can search for the desired image file 13 easily and quickly.

  Next, clustering processing using the event setting table 27 will be described. FIG. 10 shows an example of the event setting table 27 and the TPO database 23. The event setting table 27 holds date / time information 27a that holds the date and time, place information 27b that holds the name of the place, and event information 27c that holds the name of the event. The user sets a schedule for the event setting table 27 displayed on the display unit 15. Here, as a schedule, for example, attendance at a birthday party held in Nara city from 20:00 to 22:00 on February 5, 2012 is set. At this time, the date information 27a holds “February 5, 2012 from 20:00 to 22:00”, the location information 27b holds “Nara City”, and the event information 27c holds “Birthday Party”.

  The CPU 10 stores the image file name 23a, the shooting period name 23b, and the shooting area name 23c in the TPO database 23 in response to the image file 13 being shot using the camera imaging unit 18. Next, the CPU 10 refers to the event setting table 27. The CPU 10 confirms whether or not the shooting period name 23b corresponds to the date / time information 27a and the shooting area name 23c corresponds to the location information 27b. For example, when the shooting period name 23b is "February 5, 2012 20: 20: 7" and the date / time information 27a is "February 5, 2012 from 20:00 to 22:00", the CPU 10 It is determined that 23b corresponds to the date information 27a. Further, when the shooting area name 23c is “Omiya, Nara City, Nara Prefecture, Japan” and the location information 27b is “Nara City”, it is determined that the shooting area name 23c corresponds to the location information 27b.

  When the shooting period name 23b and the shooting area name 23c correspond to the date / time information 27a and the shooting area name 23c, the CPU 10 causes the TPO database 23 to hold “birthday party” of the event information 27 as the event name 23d. Thus, the user can hold the character string “birthday party” as the event name 23d in the TPO database 23 without inputting the character string. The user can cluster the image file 13 using the event name 23d. Further, the user can change the existing clustering name or the name of the image file 13 to a name including the event name 23d. Thus, by using the event setting table 27, the user can not only manage his / her schedule but also cluster the image file 13 based on the event name 23d.
