<p>PURPOSE:To obtain a portrait image encoding system by which a processing is easy and whose data compression efficiency is high. CONSTITUTION:At the time of encoding, a portrait original image 101 undergoes expression/motion-analysis 102 and is parameter-conversion 103. Then, an expression/motion parameter 107 for three-dimensional models 104a-c is obtained. The three-dimensional models are constituted of plural models different in resolution and expression areas, and they are adaptively switched by the moving amount 106 of a whole head part or the face. At the time of decoding, one of three-dimensional models 104d-f is modeldeformed 109 by the expression/ motion parameter 107 and a decoding picture 112 can be obtained through the processing of luminance/color addition 110 based on an initial image 111.</p> |
