The invention aims to reduce, in performing autofocusing on an autofocus target region determined within a face region obtained by face detection, the risk of misfocusing attributable to a background image included in the autofocus target region. To this end, a face detecting unit firstly performs face detection to determine a face region including a human face image. Then, an AF target region determination unit determines an AF target region within the face region. In this event, the AF target region determination unit can change the area ratio of the AF target region to the face region. Thereafter, based on contrast of a region, corresponding to the AF target region determined by the AF target region determination unit, of captured image data, an AF evaluation value calculation unit, a controller and a lens driving unit adjust a location where a subject image is formed by a shooting optical system.
