A video conference system includes terminals where each terminal extracts only an object image from a picture that includes an object and a background. The extracted object image signal is transmitted to a controller to be synthesized on a background image, and a synthesized image is simultaneously transmitted to a plurality of terminals. Each of the plurality of terminals encodes only an object image signal corresponding to a conference participant out of a photographed video signal to output an encoded object signal. Each terminal receives and decodes a compression-encoded image signal to display a compressed image. A multi-point controller receives and decodes the encoded object signals from the plurality of terminals to restore object images, adjusts the size of the object images, synthesizes a background image with the size-adjusted object images, and compression-encodes the synthesized image to output the compression-encoded image signal to the plurality of terminals.
