ABSTRACT:
A video telephone displays a still picture in a first picture mode and a still picture in a second picture mode, which is smaller than that of the first picture mode, using image data transmitted over an audio signal transmission line and includes a memory having an address capacity corresponding to the size of the still picture in the first picture mode. In this video telephone, when image data of the still picture in the first picture mode is received, the image data is written in all addresses of the memory and, when image data of the still picture in the second picture mode is received, the image data is written only in predetermined addresses of the memory. This permits the same display read-out for all addresses of the memory to display the still picture whether in the first or second picture mode.
