Abstract
A still picture picturephone communication system for transmitting and receiving a still picture over a telephone circuit including a handshaking process wherein prior to still picture transmission, identification code data indicating a function of the picturephone set is transmitted and received, and a decision is made as to whether the still picture is being transmitted or not. A designation code of a desired response waiting time within an identification code data used at the time of handshaking is formed, and the response is delayed by a period of time corresponding to the response waiting time. A still picture data is directly transmitted and received without handshaking. In addition character data including character information and the like can be transmitted and received, and by manipulating the picturephone set of one party the picturephone set of the other party can be made to transmit picture data therefrom. Furthermore, the picture sent from the called party can be transferred to a third party.
