Then, after determining whether or not an area display image needs to be inserted, which will be described in detail below, this image data file is written to the recording medium M via the card interface 16 by processing in the file access unit 26.

  The main control unit 12 includes an area display image setting unit 30. The area display image setting unit 30 refers to the area related information data storage unit 31 in which the area information is stored in association with the position information and the area display image data, and the area related information data storage unit 31 to capture an image. And an area determination unit 32 for determining whether or not the shooting position of the shot image obtained in the same area as the shooting position of the shot image obtained immediately before is determined to be not in the same area. In this case, the area display image generation unit 33 generates an area display image representing the area information of the area including the shooting position based on the area-related information data, and the generated area display image is displayed in the order of display of the shot image. And an area display image insertion unit 34 to be inserted at the position.

The data structure of the area related information data stored in the area related information data storage unit 31 is schematically shown in FIG. As shown in FIG. 6A, area sections are assigned to predetermined longitude areas and latitude areas, and position information and area sections are associated with each other. For example, in FIG. _{6 (a), LaX m +} 1 LoY n is assigned as the area division to a region of the latitude value X _m ~X _{m + 1} and longitude values Y _n-1 ~Y _n. Further, as shown in FIG. 6B, each area classification is further associated with the area name and area display image data representing area information of the area. Here, the area name is not limited to the place name of the area, but includes a name symbolizing the area (such as a typical building name of the area). The area-related information data is updated by connecting the digital camera to a computer main body (not shown) connected to the network using a cable C, and acquiring update information transmitted via the network. It is configured.

  The area determination unit 32 acquires the position information (shooting position information) of the shot image via the tag information generation unit 24 and takes a picture immediately before being recorded on the recording medium M via the file access unit 26. The obtained photographed image (latest photographed image) is selected based on the tag information of the image data file, the position information of the selected photographed image is acquired from the tag information, and these position information is referred to the area related information data. Whether or not the shooting position is in the same area is determined. In addition, it is good also as a structure which transmits imaging | photography position information directly from the GPS unit 13 to the area determination part 32, and is provided with the position information storage part which memorize | stores the positional information on the newest imaging | photography image recorded on the recording medium M separately.

  When the area determination unit 32 determines that the shooting position is not in the same area, the area display image generation unit 33 displays area information representing area information of the area including the shooting position from the area display image data in the area-related information data. Generate an image. Note that the area display image to be generated is the same as the format of the captured image, thumbnail image data is also generated, a file name and the like are given to the file information, and an image data file is generated in the same manner as the captured image. . Also, identification information indicating an area display image is also given to the image data file.

  When the area determination unit 31 determines that the shooting position is not in the same area, the area display image insertion unit 34 inserts the area display image generated by the area display image generation unit 33 at the position in the display order of the captured image. To do. Specifically, when the area display image is not inserted, the next value of the file number of the latest photographed image recorded on the recording medium M is set as the file number of the photographed image input by photographing. However, when an area display image is inserted, the next value of the file number of the latest captured image recorded on the recording medium M is input to the file number of the area display image, and the next value is input by shooting. Set to the file number of the captured image. That is, the image data file of the area display image has a number one smaller than the file number assigned to the image data file of the first photographed image among the photographed images in the same area as the area display image as the file number of the image data file. To be granted.

  The display control unit 27 sequentially displays the captured images in the order of the file numbers on the liquid crystal display unit 5 and displays the area display image at the insertion position. Further, by operating the control button 7, a processing menu is displayed on the liquid crystal display unit 5 via the operating system 28 and the display control unit 27. The processing mode of the main control unit 12 is set so that the user can select a process required by the user from a plurality of processes displayed on the process menu.

First, when the photographed image P is input by photographing, position information of the digital camera at the time of photographing, that is, information on the photographing position (photographing position information) is acquired (# 01). Next, the latest photographed image _An-1 recorded on the recording medium M is selected based on the photographing date / time or file number included in the image data file, and the position information of the photographed image _An-1 is selected from the tag information. Obtain (# 02). It is assumed that the file number of the selected photographed image _An-1 is n-1. Then, for the acquired position information, the area to which the shooting position belongs is specified with reference to the area related information data (# 03).

When the area including the shooting positions of the shot image P and the shot image _An-1 is specified, it is determined whether or not they are in the same area (# 04). If it is determined that they are not in the same area (# 04 No branch), an area display image representing the area information of the area including the shooting position of the shot image P is generated from the area display image data in the area related information data (# 05). In addition, as described above, an image data file is also generated.

  FIG. 7 shows an example of the generated area display image. A typical building (an example of area information) in the area where the captured image P is captured is B Castle, and a symbol image (painting image) of B Castle is generated as the area display image. In this image, the area name (B Castle) is synthesized as a character image, and the number of shots is displayed when the number of shot images in the area is determined.

  In order to insert the generated area display image at a position in the display order of the captured image P, a file number n is assigned to the image data file of the area display image (# 06). A file number n + 1 is assigned to the image data file of the captured image P (# 07). As a result, the captured image P is positioned next to the area display image.

The captured image P to which the file number is assigned and the image data file of the area display image are recorded on the recording medium M via the file access unit 26 (# 09). On the other hand, when it is determined that the shooting positions of the shot image P and the shot image _An-1 are in the same area (# 04 Yes branch), the file number n is assigned to the image data file of the shot image P and recorded. It is recorded on the medium M (# 09).

The display control unit 27 sequentially displays the thumbnail image data on the liquid crystal display unit 5 in the order of the file number of the image data file. Therefore, as shown in FIG. 8, when the area display image is not inserted, the photographed image P (file number n) is next to the photographed image _An-1 (file number n-1) as shown in FIG. ) Is displayed, but when an area display image is inserted, as shown in (b), the captured image A _n-1 (file number n-1), the area display image (file number n), and the captured image P are displayed. They are displayed on the liquid crystal display unit 5 in the order of (file number n + 1).

  Further, as described above, the display control unit 27 includes the table of contents screen generation unit 27a. When the table of contents screen display is selected from a processing menu screen (not shown), the table of contents screen generation unit 27a displays the recording medium M. The file name of the area display image recorded in the table is read out, and a table of contents screen as illustrated in FIG. 9 is displayed as a table of contents item (table of contents information). In FIG. 9, the right column of each table of contents item (area a, area b, area c) shows the number of captured images included in the area. When the user selects a desired table of contents item from these table of contents items, an area display image corresponding to the selected table of contents item is displayed on the liquid crystal display unit 5, and this area is displayed by operating the control button 7. The captured images can be sequentially displayed using the display image as a base point.

Furthermore, in this embodiment, the area display image is generated in the same format as the captured image, and the image data file is recorded on the recording medium M together with the image data file of the captured image. The area display image is also printed out at the insertion position. That is, a photographic print can be obtained in the order of the photographic image A _n-1 , the area display image, and the photographic image P. In addition, when the photographic print of the area display image is not necessary and the display on the liquid crystal display unit 5 is sufficient, only thumbnail image data may be generated.

First, when the photographed image P is input by photographing, position information of the digital camera at the time of photographing, that is, information on the photographing position (photographing position information) is acquired (# 11). Next, this photographing position information is transmitted to the server S via the transmission / reception unit 19 (# 12).

  In the server S, first, shooting position information is received (# 101), and based on the received shooting position information, the area related information of the area to which the shooting position belongs is extracted with reference to the area related information database 52 (# 102). This is transmitted to the digital camera (# 103).

  In the digital camera, the area-related information from the server S sent in response to the transmission of the shooting position information is acquired (# 13), and the latest area display image recorded in the recording medium M is read out (#). 14). Then, the two area display images are compared, and if they are the same, if the shooting position is in the same area, it is determined that they are not in the same area if they are different (# 15). The area information transmitted last time may be stored separately, and the area information transmitted from the server S may be compared to perform area determination.

  If it is determined that the shooting position is not in the same area (# 15 No branch), processing for converting the area display image data in the acquired area-related information into the same format as the shot image is performed, which is the same as the shot image An image data file is generated (# 16).

  Next, in order to insert the area display image at the position in the display order of the captured image P, a file number is assigned to the image data file of the area display image (# 17). If the file number of the recorded photographed image is n-1, the file number n is assigned. A file number n + 1 is assigned to the image data file of the captured image P (# 18). As a result, the captured image P is positioned next to the area display image.

  The captured image P to which the file number is assigned and the image data file of the area display image are recorded on the recording medium M via the file access unit 26 (# 20). On the other hand, when it is determined that the shooting position is in the same area (# 15 Yes branch), the file number n is assigned to the image data file of the shot image P (# 19), and is recorded on the recording medium M ( # 20). As a result, the image data files are sequentially displayed on the liquid crystal display unit 5 in the order of the file numbers.

[Another embodiment 2]
In the above-described embodiment, the area display image is inserted when the areas including the shooting positions are different. However, even if the areas including the shooting positions are the same, the shooting date and time intervals are separated by a predetermined period or more. In such a case, an area display image representing the period information may be inserted together with the area information.

  For example, in the first embodiment, the area related information data storage unit 31 stores an area display image representing period information together with the area information as area display image data associated with the period information. Further, when the area determination unit 32 determines that the shooting position of the shot image is in the same area, the area determination unit 32 is further configured to determine whether or not the interval between shooting dates is within a predetermined period. This predetermined period can be set based on the period of the period information associated with the area display image data, for example. And when it determines with it not being in a predetermined period, the area display image generation part 33 is comprised so that an area display image may be produced | generated based on the area display image data which include the said imaging | photography date in the period of a period information. The area display image generated in this way is inserted by the area display image insertion unit 34.

In this case, the processing after it is determined that the captured image P input by imaging and the latest captured image _An-1 recorded on the recording medium M are in the same area is as follows. First, the shooting date and time is acquired from the image data file of the shot image P or directly from the clock unit 17, and whether or not this shooting date and time is included in the period set in the period information of the area display image corresponding to the shot image _An-1. To determine. If it is determined that the shooting date / time is not within the period, an area display image is generated based on another area display image data associated with the period information including the shooting date / time, and this is displayed as the shot image P. Insert at the position before the display order. On the other hand, if it is determined that the shooting date / time is within that period, the area display image is not inserted.

  Also in the above-described first embodiment, if the area display image representing the period information together with the area information is stored in the area related information database 52 of the server S as the area display image data associated with the period information. Good. Upon receiving the shooting position information transmitted from the digital camera, the server S refers to the area related information database based on the shooting position information and the reception date and time, and obtains area display image data of the area including the shooting position. Then, the area display image data including the reception date and time in the period set in the period information is selected and transmitted to the digital camera. In the digital camera, whether or not insertion is necessary is determined by comparing whether or not the transmitted area display image is the same as the previously transmitted area display image. As a result, even if the area including the shooting position is the same, if the shooting interval is longer than a predetermined period and, as a result, a different area display image is transmitted, the area display image is inserted. Become.

  In addition, even when the area including the shooting position is different, the area display image including the shooting date and time in the period determined by the period information by referring to the period information from the area display image data of the area including the shooting position. A configuration may be adopted in which data is extracted and inserted.

[Another embodiment 3]
In the above-described embodiment, the area display image is configured as a composite image of the symbol image and the character image. However, the area display image may be configured by the symbol image or the character image. In particular, by using only a character image, it is possible to reduce the amount of data and make it easier to identify the captured image.

[Another embodiment 4]
A configuration may be used in which area-related information such as area information and area display image is held inside the digital camera and acquired from an external device (server). Moreover, you may comprise so that a part of area related information may be hold | maintained at a digital camera and others at a server. For example, the area information associated with the position information may be held inside the digital camera, and the area display image may be acquired from the server according to the area determination result.
