Imaging device, focusing control method of the imaging device, and integrated circuits

An imaging apparatus for focusing in a contrast method in the face image region to improve the stability of the focus control. By a face image retrieval using a threshold Thf1 by person image retrieval and face detection circuit 3 using the threshold Thh1 by the person detecting circuit 2, a face image corresponding to the face of the whole body image area and the same person, corresponding to the whole body of a person If the region and was detected in the captured image, the face detection circuit 3, the detected face image area, re-determination using the threshold Thf2 can search the face image with higher accuracy than the facial image search using the threshold Thf1 I do.
