Claim:
1. An image pickup apparatus comprising: an image pickup device that receives a pair of light beams that pass through different pupil division areas of an imaging optical system with a pair of photoelectric conversion sections; an emission unit that illuminates an object; an extraction unit configured to extract light-control target area candidates from a pre-emission image that is obtained by pre-emitting said emission unit using a non-emission image and the pre-emission image; a calculation unit configured to find focused areas and defocus areas in the pre-emission image based on the pre-emission image; a selection unit configured to select a light-control target area that should be a target of light control from the light-control target area candidates according to information based on the focused areas; and a control unit configured to control emission quantity of said emission unit at a time of photographing so that luminance in the light-control target area becomes predetermined luminance, wherein said calculation unit finds the information about the focused areas based on difference information between a first phase difference signal read from one photoelectric conversion section of the pair of photoelectric conversion sections and a second phase difference signal read from the other photoelectric conversion section of the pair of photoelectric conversion sections.
