  FIG. 2 is a flowchart showing the operation of the transmitting terminal, and FIG. 3 is a flowchart showing the operation of the receiving terminal.

  First, referring to FIG. 2, the mobile terminal 100 captures an image of an object (step A1) and selects whether to store the captured image in the mobile terminal (step A2). If not stored, the photographed image is deleted and the camera returns to the photographing mode again (step A1).

  When the image is stored, it is selected whether or not the position information is continuously acquired (step A3). When not acquiring, it progresses to step A8 and preserve | saves only an image.

  When acquiring position information, next, the GPS antenna 101 is accessed to the GPS satellite 800, and the latitude and longitude of the current location are acquired (step A4). It is selected from the acquired latitude / longitude data 20 whether or not to acquire more detailed information or more detailed position information (step A5). When acquiring, a map and an address using the position information providing system 900 are selected. Data is converted and transmitted to the mobile terminal 100. Next, the weather information 40 is acquired from the weather information server 700 on the Internet using the acquired position information 30 (step A6), and it is determined whether or not to save (step A7). When not saving, it is selected whether detailed information is reacquired (step A9). If reacquisition is performed, the process proceeds to step A6. If only the image and the latitude / history data 20 are not reacquired, the process proceeds to step A8.

  When the acquired information is stored in step A7, it is stored in the memory 105 of the portable terminal 100 as image data 30 together with the image (step A8). If the stored image is to be transmitted to another terminal, the process proceeds to Step A10. If not, the process is terminated.
