PROBLEM TO BE SOLVED: To control a data communication amount when a recorded image of a camera is reproduced at a terminal device side.SOLUTION: When communication connection between a terminal device 20 and a camera 10[1] is established, the terminal device 20 requests reproduction set data (reproduction image data about an object image, a camera ID specific to the camera 10[1], and image identification information specific to the object image) from the camera 10[1]. When the terminal device 20 receives the reproduction set data transferred by the camera 10[1], it displays an image based on the reproduction image data, and on the other hand holds the reproduction set data. After communication disconnection, when communication connection is established between the terminal device 20 and a camera 10[j], the terminal device 20 receives a camera ID and image identification information from the camera 10[j] which is a reconnection device, and checks those with the held reproduction set data. If the terminal device 20 has checked that they accord, it displays an image based on the held reproduction image data again. |
