Abstract

PURPOSE:To reduce information quantity and to economize a transmission by selecting a mouth shape parameter based on a phoneme in voice information transmitted and deforming a mouth shape model image. CONSTITUTION:A corresponding mouth shape parameter is selected from a code book 23 and sent to a memory 24 by a phoneme code in voice information from a transmitter side. The mouth shape model image previously stored is deformed for each parameter in the memory 24, is synthesized by a synthesizing part 25 with a face moving image except the mouth part sent from the transmitter side and the moving image of a face is reproduced. Consequently, since the transmission image is only face image information except the mouth part of a speaker, information quantity can be reduced.
