  Next, the CPU 8 receives the location information, the communication address, and the reception availability information of the communication terminal via the wireless communication unit 48 and stores them in the memory 34 (step S5).

  Next, the CPU 8 reads out the position information of the communication terminal in the receivable state from the memory 34 and the image data of the image indicating that it is in the receivable state from the image storage unit 42, and the position information of the communication terminal on the through image. An image indicating that reception is possible is superimposed and displayed at a position corresponding to (step S6). For example, when the communication terminals of the person 1 and the person 3 are in a receivable state, as shown in FIG. 3, an image indicating that the person 1 and the person 3 are in a receivable state is superimposed on the position of the person 1 and the person 3. To do. Similarly, the position information of the communication terminal that is not in a receivable state is read from the memory 34, and the image data of an image indicating that it is not in the receivable state is read from the image storage unit 42, and corresponds to the position information of the communication terminal on the through image. An image indicating that the position is not in a receivable state is superimposed and displayed (step S6). For example, when the communication terminal of the person 2 is not in a receivable state, an image indicating that the person 2 is not in a receivable state is superimposed and displayed at the position of the person 2 as shown in FIG. Here, when there is no communication terminal in a receivable state within the range displayed in the through image (step S7: No), the CPU 8 ends the series of processes.

  On the other hand, when there is a communication terminal in a receivable state within the range displayed in the through image (step S7: Yes), the CPU 8 determines whether or not the image list display button has been pressed (step S8). . When the image list display button is pressed (step S8: Yes), the CPU 8 reads the thumbnail image data added to the image data stored in the memory card 44, and displays a list of thumbnail images on the LCD display unit 26. To do.

  When the operator operates the multi-selector and the OK button to select a desired image from the thumbnail image list, the CPU 8 stores the image data of the image corresponding to the selected thumbnail image in the memory card 44. To read memory 34.

  Next, the CPU 8 determines whether or not there is a known communication terminal among the communication terminals in a receivable state existing in the range displayed in the through image (step S9). That is, the CPU 8 collates the communication address of the communication terminal in a receivable state with the communication address stored in advance in the personal information storage unit 40, and recognizes the communication terminal with the matching communication address as a known communication terminal. If there is no known communication terminal (step S9: No), the process proceeds to step S13.

  On the other hand, when there is a known communication terminal (step S9: Yes), the CPU 8 displays on the LCD display unit 26, for example, “Can the selected image data be transmitted to the communication terminal whose address is registered?” After the display, a “Yes / No” selection screen is displayed (step S10). If “No” is selected (step S10: No), the process proceeds to step S13.

  When “Yes” is selected (step S10: Yes), the image data of the image corresponding to the selected thumbnail image is read from the memory 34, and together with the communication address of the communication terminal recognized as a known communication terminal, the wireless communication unit It transmits to a web server via 48 (step S11). The image data transmitted to the web server together with the communication address is transmitted to the communication terminal corresponding to the communication address by the web server. Here, when the communication terminals in the receivable state are only known terminals, the series of processes is terminated (step S12: Yes).

  On the other hand, when the communication terminal in the receivable state is not the only known terminal (step S12: No), the CPU 8 determines whether or not the communication terminal in the receivable state is selected from the communication terminals other than the known communication terminal. A determination is made (step S13). When the communication terminal is selected (step S13: Yes), for example, when the multi-selector and the OK button are operated by the operator and an image indicating that reception is possible on the through image is selected, the CPU 8 Reads out the communication address of the communication terminal corresponding to the image data selected in step S8 and the image indicating that the selected receivable state is received from the memory 34, and transmits it to the web server via the wireless communication unit 48 ( Step S14). The image data transmitted to the web server together with the communication address is transmitted to the communication terminal corresponding to the communication address by the web server. On the other hand, when the communication terminal is not selected, the CPU 8 ends the series of processes (step S13: No).

  Here, when the web server has location information, a communication address of the communication terminal that can communicate with the web server, possession information indicating whether the communication terminal has information data that can be transmitted, and information data that can be transmitted. The information data is stored for each communication terminal. When receiving the current position information and current direction information from the digital camera 2, the web server detects a communication terminal located in the direction of the current shooting direction with reference to the current position information, and detects the detected position information of the communication terminal The communication address and possession information are transmitted to the digital camera 2.

  Next, the CPU 8 receives the location information, the communication address, and the possession information of the communication terminal via the wireless communication unit 48 and stores them in the memory 34 (step S25).

  Next, the CPU 8 reads the position information of the communication terminal having the information data from the memory 34 and the image data of the image indicating that the information data is included from the image storage unit 42, and corresponds to the position information of the communication terminal on the through image. An image indicating that the information data is present at the position to be displayed is superimposed (step S26). For example, when the communication terminals of the facility 1 and the person 4 have information data that can be transmitted, as shown in FIG. 5, an image indicating that the information data is held at the position of the facility 1 and the person 4 is superimposed and displayed. . Similarly, the position information of the communication terminal having no information data is read from the memory 34, and the image data of the image indicating that the information data is not included is read from the image storage unit 42, and the position information of the communication terminal is displayed on the through image. An image indicating that there is no information data at the corresponding position is superimposed and displayed (step S26). In addition, since there is no communication terminal that does not have information data in the range of the through image illustrated in FIG. 5, an image indicating that no information data is present is not displayed. Here, when there is no communication terminal having information data in the range displayed in the through image (step S27: No), the CPU 8 ends the series of processes.

  On the other hand, if there is a communication terminal having information data in the range displayed in the through image (step S27: Yes), the CPU 8 is a known communication terminal among the communication terminals existing in the range displayed in the through image. It is determined whether or not there is (step S28). That is, the CPU 8 collates the communication address of the communication terminal existing in the range displayed in the through image with the communication address stored in advance in the personal information storage unit 40, and determines the communication terminal having the same communication address as the known communication. Recognize as a terminal. If there is no known communication terminal (step S28: No), the process proceeds to step S32.

  On the other hand, when there is a known communication terminal (step S28: Yes), the CPU 8 displays on the LCD display unit 26, for example, "Can I receive data from the communication terminal whose address is registered?" After that, a “Yes / No” selection screen is displayed (step S29). When “No” is selected (step S29: No), the process proceeds to step S32.

  When “Yes” is selected (step S29: Yes), the communication address of the communication terminal recognized as a known communication terminal is transmitted to the web server via the wireless communication unit 48. When receiving the communication address from the digital camera 2, the web server transmits information data of the communication terminal corresponding to the communication address to the digital camera 2.

  Next, the CPU 8 receives information data of the communication terminal via the wireless communication unit 48 and stores it in the memory 34 (step S30). The information data stored in the memory 34 is then stored in the memory card 44. Here, when the communication terminals existing in the range displayed in the through image are only known terminals, the series of processing ends (step S31: Yes).

  On the other hand, when the communication terminal existing in the range displayed in the through image is not the only known terminal (step S31: No), the CPU 8 determines whether a communication terminal other than the known communication terminal is selected (step S31). S32). When the communication terminal is selected (step S32: Yes), for example, the operator operates the multi-selector and the OK button, and an image indicating that there is information data of a communication terminal that is not a known terminal on the through image is selected. If so, the CPU 8 reads the communication address of the communication terminal corresponding to the selected image from the memory 34 and transmits it to the web server via the wireless communication unit 48. When receiving the communication address from the digital camera 2, the web server transmits information data of the communication terminal corresponding to the communication address to the digital camera 2.

  Next, the CPU 8 receives the information data via the wireless communication unit 48 and stores it in the memory 34 (step S33). The information data stored in the memory 34 is then stored in the memory card 44. On the other hand, when the communication terminal is not selected (step S32: No), the CPU 8 ends the series of processes.

  According to the digital camera 2 according to this embodiment, a through image is received by receiving a communication address, reception availability information, and the like of a communication terminal located in the direction of the current shooting direction on the basis of the current position information from a web server. It is possible to communicate with a communication terminal that exists in the range displayed within. In addition, an image indicating whether the communication terminal is in a receivable state or an image indicating whether the communication terminal has information data that can be transmitted is superimposed and displayed at the position of the position information of the communication terminal on the through image. By doing so, the operator can easily recognize whether communication with other communication terminals is possible. In addition, when there is a known communication terminal, data can be transmitted and received promptly without performing an operation such as selecting a communication terminal.

  In the above-described embodiment, processing is performed by distinguishing between the transmission mode and the reception mode, but the processing in the transmission mode and the reception mode may be performed collectively. Accordingly, an image indicating whether or not the communication terminal is in a receivable state and an image indicating whether or not the communication terminal has information data that can be transmitted can be simultaneously displayed on the same screen.

  Further, in the reception mode of the above-described embodiment, it may be possible to determine whether or not reception is possible before receiving information data and to receive only the information data determined to be receivable. For example, when the reception request button is pressed by the operator while an image indicating that the information data is displayed on the through image, the CPU 8 generates reception request information and sends the information to the web server. A reception request for reception determination information for determining whether or not data can be received is made. Next, the CPU 8 determines whether or not the information data can be received based on the reception determination information received via the wireless communication unit 48. When there are communication terminals having receivable information data, the CPU 8 receives information data from those communication terminals. When there is no communication terminal having receivable information data, the CPU 8 ends the series of processes. .

  The reception determination information may be category information indicating a category such as a store or an office. That is, it is assumed that, for example, the category “restaurant” is selected by the operator in a state where the category information of the information data included in the communication terminals of the facility 1 and the person 4 (see FIG. 5) is received by the reception request. The CPU 8 collates the received category information with the selected category of restaurant, and determines whether or not the received category information includes information related to the restaurant.

  Here, when the category information about the facility 1 includes information related to the restaurant and the category information about the person 4 does not include information related to the restaurant, the CPU 8 can receive the information data held by the communication terminal of the facility 1. It is determined that the information data of the communication terminal of the person 4 cannot be received.

  The reception determination information may be age information indicating how many years of age the communication terminal holder can transmit information data. That is, it is assumed that the operator's age is designated by the operator in a state where the age information of the information data held by the communication terminal of the facility 1 (see FIG. 5) is received by the reception request. The CPU 8 collates the received age information with the specified age, and determines whether or not the information data of the communication terminal having the received age information can be received. For example, it is assumed that the received age information about the facility 1 indicates that it can be transmitted to a communication terminal holder 18 years of age or older. On the other hand, it is assumed that the operator designates his / her age as 19 years old. In this case, the CPU 8 determines that the information data included in the communication terminal of the facility 1 can be received.

  The reception determination information may be expiration date information indicating the expiration date of the information data. That is, when the expiration date information of the information data held by the communication terminal of the facility 1 (see FIG. 5) is received by the reception request, the CPU 8 collates the received expiration date information with the received date and time, and receives the received expiration date information. It is determined whether the information data of the communication terminal having can be received. For example, it is assumed that the expiration date information about the received facility 1 is July 31, 2010. Here, when the date and time when the expiration date information of the information data held by the communication terminal of the facility 1 is received as of August 10, 2010, the CPU 8 does not receive the information data held by the communication terminal of the facility 1. Judge that it is possible.

  The reception determination information may be capacity information indicating the capacity of information data. That is, when the capacity information of the information data possessed by the communication terminals of the facility 1 and the person 4 (see FIG. 5) is received by the reception request, the CPU 8 receives the sum of the capacity based on the received capacity information and a preset reception. The available capacity is collated, and it is determined whether or not the information data of the communication terminals of the facility 1 and the person 4 can be received. For example, when the capacity that can be received by the digital camera 2 is 1 GB, the capacity information about the facility 1 indicates that the information data of the communication terminal of the facility 1 is 700 MB, and the capacity information about the person 4 is It is assumed that the information data that the communication terminal of the person 4 has is 500 MB. In this case, since the total amount of information data based on the capacity information exceeds 1 GB, the CPU 8 determines that the information data held by the communication terminals of the facility 1 and the person 4 cannot be received.

  In the reception mode of the above-described embodiment, an image indicating whether or not the information data is present at a position corresponding to the position information of the communication terminal on the through image is superimposed and displayed, but the communication terminal can transmit An image indicating whether or not it is in a state may be superimposed and displayed. That is, the CPU 8 receives the reception determination information from the web server, and determines whether or not the information data can be received based on the reception determination information. Then, an image indicating that it is in a transmittable state or an image indicating that it is not in a transmittable state may be superimposed and displayed at a position corresponding to the position information of the communication terminal on the through image.

  In the above-described embodiment, the web server detects the communication terminal located in the direction of the current shooting direction with reference to the current position information of the digital camera 2, but further detects the communication terminal to be detected. You may limit to the thing located in the predetermined distance on the basis of the current position information of the digital camera 2. For example, only communication terminals located within 10 m with respect to the current position of the digital camera 2 in the direction of the shooting direction of the through image may be detected.

  In the transmission mode of the above-described embodiment, the case where image data is read from the memory card 44 and transmitted to the web server is described as an example, but the type of data transmitted to the web server is not limited. For example, the mail data of the created e-mail may be transmitted to the web server.

  Further, in the transmission mode of the above-described embodiment, the image indicating that it is not in the receivable state is shown by hatching as shown in FIG. Any display method can be used as long as the image can be displayed. For example, an image indicating that it is in a receivable state may be displayed in cream, and an image indicating that it is not in a receivable state may be displayed in red. Similarly, in the reception mode, any display method may be used as long as the operator can intuitively understand that no information data is provided.
