<First embodiment>
The digital camera 1 acquires information on the current position by the position information acquisition unit 79, and selects one image from a plurality of image files in the folder recorded on the external recording medium 70 by the cross button 16 and the menu / OK button 17. The file is selected, and the image file analyzing unit 83 analyzes the position information set for each of the main image data identifier and the sub image data identifier of the selected image file, and at the time of reproduction on the monitor 14, The image data after the identifier having the analyzed position information closest to the information is reproduced.

  The MP file (Multipage Format file) refers to one image file configured by connecting a plurality of image data. For example, main image data I1 obtained by imaging as shown in FIG. Sub-image data I2 to In, a main identifier H1 in which time information and current position information related to the main image data I1 are set is provided in front of the main image data I1, and one or more sub-image data This is an image file provided with sub-identifiers H2 to Hn in which time information and current position information related to each sub-image data is set before each of I2-In. One or more image data related to the main image data and the corresponding sub-identifier can be stored in the extension data area.

  5A and 5B are a series of process flowcharts of the digital camera 1. First, as shown in FIG. 5A, the CPU 75 selects the MP file imaging mode in accordance with the selection of the operation mode dial 11 (step ST1). Then, the CPU 75 determines whether or not an image display mode is additionally set in the reproduction mode selected by the power lever 8 (step ST2). When the image display mode is not set (step ST2; NO), the process proceeds to another imaging mode process (step ST15). On the other hand, when the image display mode is set (step ST2; YES), the folder (MP file is recorded) recorded on the external recording medium 70 by the setting of the cross button 16, the menu / OK button 17, etc. from the user. ) Is selected (step ST3). The display control unit 71 displays thumbnails of a plurality of image data stored in the MP file in the selected folder and the file names recorded in the respective identifiers (main image data identifier and sub image data identifier). The information is displayed on the monitor 14 (step ST4). The user selects a desired image file recorded on the external recording medium 70 by setting the cross button 16 and the menu / OK button 17 (step ST5). If not selected (step ST5; NO), the wait control is repeated until it is selected.

  On the other hand, when it is selected (step ST5; YES), the MP file analysis unit 83 acquires information on the main image data and main image data identifier of the image file (step ST6). Next, the time measuring part 66 acquires the information regarding the present time (step ST7). The MP file analysis unit 83 acquires the sub image data information and sub image data identifier information of the image file (step ST8). First, as shown in FIG. 5B, the MP file analysis unit 83 analyzes whether or not information (tag) related to time is recorded in the acquired sub-image data identifier. It is analyzed whether there is information on the time closest to the information on the current time acquired by the timekeeping unit 66 from the information on the time recorded in one or more sub-image data identifiers (step ST9).

  The closest time refers to the closest time within a predetermined range. For example, when the information about the time is a day of the week, and the information about the time acquired by the time measuring unit 66 is a Tuesday, The day is within a predetermined range. Therefore, the day of the week except Monday to Wednesday does not correspond to the nearest time.

  It is also possible to specify a time range. In that case, the closest time may be based on the time at the center of the above range. For example, when 9:30 to 10:30 is specified, 10 o'clock is the standard. In addition, when October 8 and October 12 are designated, October 10 is the standard.

  When the MP file analyzing unit 83 analyzes that information on the closest time is recorded (step ST9; YES), the MP file analysis unit 83 controls display of the sub image data corresponding to the sub image data identifier for recording the information on the closest time. Control is performed so that the monitor 14 is displayed on the unit 71 (step ST10). When the monitor 14 displays the sub-image data (step ST16; YES), the process is finished. On the other hand, if the monitor 14 does not display the sub-image data (step ST16; NO), the process returns to selecting a folder (step ST3).

  On the other hand, when the MP file analysis unit 83 analyzes that information regarding the nearest time within the predetermined range is not recorded (step ST9; NO), the MP file analysis unit captures an image from the acquired sub-image data identifier. Information about time is acquired (step ST11). When information related to the imaging time is recorded in the sub-image data identifier (step ST11; YES), the MP file analysis unit 83 changes the information related to the current time acquired by the time measuring unit 66 from the information related to the imaging time. The display control unit 71 is instructed to extract the closest information and display the sub image data corresponding to the sub image data identifier in which the extracted closest information is recorded on the monitor 14. On the other hand, when information related to the imaging time is recorded in the sub-image data identifier (step ST11; NO), the display control unit 71 is instructed to display the main image data on the monitor 14 as it is.

  The time-related information is any one of a year, a month, a day, an hour, a minute, a second, a day of the week, a holiday and a weekday. The digital camera 1 has a database (not shown), and can be converted into a desired time segment from the time acquired by the time measuring unit 66 or the imaging time recorded in the identifier, and from the converted information. Analysis and comparison of time information is possible. The same applies to the embodiments described later.

Next, the position information acquisition unit 79 acquires current position information (step ST66). The timekeeping unit 66 acquires information regarding the current time (step ST67). The MP file analysis unit 83 acquires the sub image data information and sub image data identifier information of the image file (step ST68). First, as shown in FIG. 10B, the MP file analysis unit 83 analyzes whether or not position information (tag) is recorded in the acquired sub-image data identifier. If there is no position information recorded as a display designation in the sub-image data identifier (step ST69; NO), the MP file analyzing unit 83 records time information (tag) in the acquired sub-image data identifier. Whether or not is analyzed (step ST71). On the other hand, when there is position information as a display designation in the sub-image data identifier (step ST69; YES), the recorded position information closest to the current position acquired by the current position acquisition unit 79 is recorded next. The sub image data corresponding to the sub-identifier to be extracted is extracted (step ST70), and the MP file analyzing unit 83 determines whether time information (tag) is recorded in the sub-image data identifier corresponding to the extracted sub-image data. This is analyzed (step ST71).

  The closest position refers to the closest position within a predetermined range.For example, when the information about the position is a prefecture, when the information about the position acquired by the position information income unit 79 is Tokyo, Adjacent to Saitama and Kanagawa prefectures in Tokyo. Therefore, since prefectures that are not adjacent to Tokyo are excluded, they do not fall into the closest position.

On the other hand, when the monitor 14 does not display the sub-image data (step ST77; NO), the process returns to selecting a folder (step ST62). On the other hand, when there is no position information as a display designation in the sub-image data identifier corresponding to the sub-image data (step ST69; NO), the MP file analyzing unit relates to the imaging time from the sub-image data identifier corresponding to the sub-image data. When there is information (step ST71; NO), information regarding the imaging time is acquired (step ST73). When information related to the imaging time is recorded in the sub-image data identifier (step ST74; YES), the MP file analysis unit 83 uses the information related to the imaging time to obtain information related to the current time acquired by the time measuring unit 66. The display control unit 71 is instructed to display on the monitor 14 the corresponding sub-image data in which the information closest to is recorded (step ST75). On the other hand, when the information regarding the imaging time is not recorded in the sub-image data identifier (step ST74; NO), the display control unit 71 is instructed to display the main image data as it is on the monitor 14 (step ST76).

  Note that the MP file analysis unit 83 analyzes whether or not information (tag) related to the time of the sub image data identifier is recorded, but in addition to the sub image data, information related to the time of the main image data identifier (tag) ) Is recorded in the same manner, and if the information related to the closest time is recorded in the main image data identifier, the main image data may be set to be displayed on the monitor 14.

  If sub-image data is not extracted (step ST69), the processing from step ST71 onward is performed for all sub-image data stored in the image file selected by the folder selection.

  Further, the position information is information related to the position classification of any of the country, the prefecture, the latitude / longitude, the county, the city, and the town. The digital camera 1 has a database (not shown), and can be converted into a desired position section from the position acquired by the position information acquisition unit 79 or the imaged position recorded in the identifier. It is possible to analyze and compare information on position classification from the obtained information. It is also possible to specify a range of positions. In that case, the closest position may be based on the time at the center of the above range. For example, when a radius of 30 km is specified from a specific latitude / longitude position, the specific latitude / longitude position is used as a reference. When a radius of 20 km is specified from Asakadai Station, Asakadai Station is used as a reference.

  The same applies to the embodiments described later.
