Abstract:
An image pickup apparatus includes an object detection unit configured to detect an object, a brightness value acquisition unit configured to obtain a brightness value of each division region of an object field, an object photometric-value generation unit configured to generate a photometric value of the object from information of the object and a brightness value of each division region, a region selection unit configured to select a high brightness region, and an exposure-control photometric-value generation unit configured to generate a photometric value used for an exposure control from a photometric value of the object and a photometric value of the high brightness region.
