PROBLEM TO BE SOLVED: To reduce, in performing autofocusing on an autofocus target region determined based on a face region obtained by face detection, the risk of misfocusing attributable to a background image included in the autofocus target region. SOLUTION: A face detecting unit 130 performs face detection to determine a face region including a human face image. Then, an AF target region determination unit 131 determines an AF target region within the face region. In this event, the AF target region determination unit 131 can change the area ratio of the AF target region to the face region. Based on contrast of a region, corresponding to the AF target region determined by the AF target region determination unit 131, of captured image data, an AF evaluation value calculation unit 132, a controller 133 and a lens driving unit 134, adjust a location where a subject image is formed by a photographing optical system 10.
