Abstract
Provided is a method of controlling a digital image processing apparatus for detecting a face from continuously input images, the method comprising operations (a) to (c). In (a), if a face is detected, image information of a body area is stored. In (b), if the face is not detected, a body having the image information stored in (a) is detected. In (c), if a current body is detected after a previous body was detected in (b), an image characteristic of the previously detected body is compared to an image characteristic of the currently detected body, and a movement state of the face is determined according to the comparison result.
