Abstract
A picture communication apparatus includes an extracting circuit for extracting video data of at least one portion from video data inputted thereto, an encoder for respectively encoding the extracted video data and the remaining video data, and a multiplexer for multiplexing the encoded video data. When encoding the video data, predetermined amount of codes are allocated to the respective video data. This suppresses deterioration in the picture quality when conducting an image communication via a transmission path having a low transmission rate. The transmitted video is displayed on a contoured display.
