  In step S <b> 101, the mobile phone 2 shifts to a shooting mode, and the imaging unit 11 captures a subject in response to a user operation. In step S <b> 102, it is determined whether or not the image data indicating the captured image is to be stored in the storage unit 15 of the mobile phone 2.

  As a result of the determination, if the image is not saved, the photographed image is deleted and the process ends. Note that the processing may return to step S101. If the image is to be stored, the process proceeds to step S103. In step S103, the user is requested to determine whether or not to obtain reference position information (latitude / longitude data) as a reference. If the reference position information is not acquired based on the user's selection, the procedure proceeds to step S111, and the image (standard image data 22) is saved.

  When the reference position information is acquired, the process proceeds to step S104. In step S104, the GPS function unit 12 receives information from a GPS (Global Positioning System) satellite 7, and acquires the latitude and longitude of the current location. In step S105, the mobile phone 2 requests the user to determine whether or not auxiliary information is to be acquired from the acquired latitude / longitude data. When the user selects acquisition of auxiliary information such as detailed position information, the process proceeds to step S106. If the auxiliary information is not acquired, the process proceeds to step S109.

In step S201, the mobile phone 2 that requests sharing of the image data with auxiliary information 21 (hereinafter referred to as another mobile phone 2) selects whether to perform image sharing in response to a user operation. As a result of the selection, when the sharing of the image data 21 with auxiliary information is requested, the process proceeds to step S202, and when the image data 21 with auxiliary information 21 is not shared, the process ends. In step S202, detailed position information 26 is set in order to specify the image data 21 with auxiliary information to be shared.

  In step S203, after setting the detailed position information 26, a sharing request is transmitted to the mobile phone 2 having the image data 21 with auxiliary information. In step S204, the mobile phone 2 that has received the sharing request receives a determination result as to whether or not data sharing is permitted. If sharing is permitted as a result of the determination, the process proceeds to step S205. If sharing is not permitted, the process ends. When the sharing request is accepted in step S205, the other mobile phone 2 automatically receives the shared data from the mobile phone 2 having the image data 21 with auxiliary information.

  FIG. 6 is a flowchart illustrating the operation of the mobile phone 2 that holds the image data 21 with auxiliary information. In step S <b> 301, the mobile phone 2 holding the image data with auxiliary information 21 receives the sharing request transmitted from the other mobile phone 2. In step S302, it is determined whether or not data sharing is permitted. If sharing is permitted as a result of the determination, the corresponding data is automatically transmitted to another mobile phone 2. When sharing is not permitted (when a sharing request is not accepted), a rejection notice is transmitted to another mobile phone 2.

  When storing images taken with the mobile phone 2, additional information (location information, weather, map) is acquired from the GPS (Global Positioning System) satellite 7 and each database on the Internet, and together with the taken images The image data is stored in the mobile phone 2. The mobile phone 2 has a function of displaying such additional information on the output unit 14 of the mobile phone 2.
