Zusammenfassung:When operating as a transmitter, a cellular phone 1 stops transmission of image data even during execution of a video phone communication in the case where a difference (movement) Dv between the image data of two frame images that are continuous in time series is smaller than a predetermined value (specific value Th). On the other hand, when operating as a receiver, the cellular phone 1 displays a still picture by using the image data that has been finally received until receiving the new image data.
