ABSTRACT:
A television telephone apparatus is coupled with a home-use large-screen TV receiver and a home-use telephone, and is connectable to another television telephone apparatus of a counter party via the home-use telephone and the public telephone network. The telephone television apparatus is equipped with a camera unit, so that both of an image produced by the camera unit, and an image transmitted from the television telephone apparatus of the counter party can be simultaneously displayed on the home-use large-screen TV receiver. While the handset of the home-use telephone is used to send/receive voice of operators, voice may be reproduced from the speaker of the home-use TV receiver. Both of an intermittent moving image having a standard image density and a still image having a relatively fine image density can be transmitted/received, so that the intermittent moving image and the still image can be simultaneously displayed on the screen of the home-use large-screen TV receiver.
