    摘要: A flesh tone region detection processor (12) detects a flesh tone region from a color still image, and a projective distribution generator (13) generates the projective distribution of the detected flesh tone region. A facial region search processor (14) searches the projective distribution for a parabola using, e.g., a genetic algorithm, and extracts a facial region candidate from the position of the found parabola. A knowledge processor (15) checks based on the aspect ratio of the region, matching with facial patterns prepared in advance, or the presence/absence of a region corresponding to hair if the extracted facial region candidate is a facial region. The user can set the processing time, the number of persons to be detected, and the face area ratio as a search end condition.
