METHOD AND APPARATUS OF FACIAL IMAGE CONVERSION BY INTERPOLATION/EXTRAPOLATION FOR PLURALITY OF FACIAL EXPRESSION COMPONENTS REPRESENTING FACIAL IMAGE

An input/output control mechanism receives facial image information of different facial expressions of a plurality of human beings to provide control so that a normalization processing mechanism normalizes each facial image information. A facial expression generation mechanism converts the normalized facial image information into facial expression components, and averages the facial expression components for each facial expression to store the same as average facial expression components. The input/output control mechanism has the facial expression component converted by the facial expression generation mechanism after the applied facial image information is normalized. The facial expression generation mechanism converts the facial expression components of the applied facial image information according to a difference between an average facial expression component corresponding to a facial expression of applied facial image information and an average facial expression component of a specified facial expression. Synthesized facial image information is generated from the converted synthesized facial expression component.
