An image pickup device 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 extraction unit extracts candidates from a pre-emission image. A calculation unit finds focused areas and defocus areas in the pre-emission image. A selection unit selects a light-control target area from the candidates according to information about the focused areas. A control unit controls emission quantity so that luminance in the light-control target area becomes predetermined luminance. The 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 and a second phase difference signal read from the other photoelectric conversion section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus with emission unit, control method therefor, and storage medium storing control program therefor","description":"An image pickup apparatus capable of obtaining focusing information at the time of photometry for emission control and of controlling an emission quantity appropriately.
