The stability is improved with which focus control is performed by an image capture device that brings a face region image into focus according to the contrast method. A human detection circuit 3 performs a human image search by using a threshold value Thh1. A face detection circuit 2 performs a face image search by using a threshold value Thf1. When an entire body image region corresponding to an entire body of a person is detected and a face image region corresponding to a face of the same person is detected in the captured image through the human image search and the face image search, the face detection circuit 2 performs redetermination with respect to the face image region by using a threshold value Thf2. The redetermination by using the threshold value Thf21 has higher accuracy compared to the face image search by using the threshold value Thf1.
