In portable videophone unit 10, an image is displayed in display 11 at the point in time at which all the image data of the image to be displayed are complete, and until then, the display of the previous image is continued. Furthermore, when the completeness of all the image data of the next image to be displayed cannot be confirmed within a preset time period, or when a predetermined number of data retransmission requests has been reached when the ARQ method is employed, it is possible to discard the image data of that image and to conduct the decoding of the image data of a subsequent image.
