Human facial color can be applied to the display of virtual face image, emotional evaluation, individual identification, and remote health care. We already developed a method for emphasizing the individual characteristics in facial color based on a virtual face image using the HSV (hue, saturation, value) color space. In this paper, we propose a synthesis method for the virtual face image based on the analysis of facial color in dynamic emotional change. At first, the facial colors under the emotion of joy was determined quantitatively by using the HSV color space. Secondly, we examined the dynamic relation between the change of facial color and that of skin temperature under the joy in laughing. Finally, on the basis of these results, we synthesized enhanced facial color motion pictures based on an average facial color image from 68 females, and evaluated the effectiveness of these images through sensory evaluation by paired comparison.
