ABSTRACT:
A face-image area is decided with comparatively good accuracy. An (N−1)th frame of a subject image α1and an Nth frame of a subject image α2are obtained by sensing the image of a subject successively. Face-image detection processing is applied to the frames of the subject images α1and α2to detect face-image areas C1, C2and C3. The face-image area C2is construed to be linked to the face-image area C1, which is the corresponding face-image area. Since a face-image area that corresponds to the face-image area C3does not exist, the face-image area C3is construed as not being linked. The linked face-image area C2in the Nth frame of the subject image α2is decided upon as a face-image area. Thus, face areas can be decided with comparatively good accuracy.
