ABSTRACT:
A method of correcting the deviation of a position at which a human face is detected using a face detection frame F. An image G within the detection frame F is divided left and right along the portion of the center axis C. The degree of similarity of mirror-symmetrical relationship between the image portions G-1and G-2obtained by the division is calculated. An amount of positional deviation d that maximizes the degree of similarity and its direction are found. The frame F is moved a distance corresponding to the amount of positional deviation d in the direction. Thus, the deviation of the detection position due to the detection frame F can be corrected by a quick and simple method.
