Abstract

PURPOSE: To shorten the time required for transmission and to facilitate grasping of the screen outline by designating only the area necessary for monitor from the reception side for transmission and then magnifying the picture image up to an optional ratio at the reception side for reproduction.
CONSTITUTION: Control circuit 6 controls address conversion circuit 7 in accordance with the address control signals which are transmitted from the reception side via the circuit and received through MODEM5, and then decides the address of the data to be transmitted. According to this decided address, the data of 1-screen memory 3 is transmitted via transmission circuit 4. At the reception side, the data of the transmitted partial picture is magnified or reduced with the prescribed ratio laterally or vertically and then memorized in 1-screen memory 13 to be then repro duced through monitor picture receiver 17.
