Conversion is performed from the light quantity information and a first aperture value of the imaging optical system, so that the first aperture value is converted into a second aperture value according to the focus detection position. A conversion coefficient is set according to the second aperture value and an exit pupil distance. A correction value to correct output signals from an imaging unit is obtained according to the second aperture value and an exit pupil distance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus detection apparatus, control method thereof, and storage medium storing program","description":"Light quantity information of an imaging optical system is acquired according to a focus detection position in an imaging screen.
