Abstract:
A camera has a face detecting section, a focusing section, and a controlling section. The face detecting section detects a face area in a shooting image plane. The focusing section calculates a defocus amount based on a relative distance of a pair of images of a light beam that has passed through a shooting lens in each of a plurality of optional areas in the shooting image plane. The controlling section designates a focusing area among the optional areas based on an output of the face detecting section and performs a focusing operation of the shooting lens based on the defocus amount in the focusing area.
