When a portable telephone (2) designates a camera number of a network camera (1), a center device (3) issues an imaging command, and the center device (3) receives first image data from the network camera (1). On the other hand, the center device (3) performs model discrimination based on the information transmitted from the portable telephone (2), converts the first image data to second image data based on the model information, transmits the second image data to the portable telephone (2), and the second image data is displayed on a display section of the portable telephone (2) having received the second image data. This enables, even if the portable telephone (2) is replaced with a new one, image data appropriate to a display size of the replaced portable telephone (2) to be easily displayed.
