Abstract

PURPOSE:To contrive to improve the coding efficiency by limiting an area surrounding a human face as a narrower area than the changing area and distincting the fact area and other area in terms of the assigned bit number in coding and applying the coding to the areas thereby reproducing more naturally the face to offer easy to see picture. CONSTITUTION:An area extraction circuit 105 extracts areas of face, eye, mouth from an output of an inter-frame differential generating circuit comprising frame memories 102, 104 and a frame delay 103. The signal stored in the frame memory 102 is fed to a block forming circuit 106 for the coding and blocked and compared with the signal of the preceding frame stored in a frame memory 113 and a moving vector is obtained by a moving detection circuit 115. The obtained difference signal is fed to a moving area detection circuit 107, from which only a block including the moving area is selected and fed to the coding circuit 108 and the block address is outputted to a multiplexer circuit 110.
