Abstract
An image capturing apparatus comprises an image sensor comprising an imaging pixel for receiving light through an opening with a center position coincident with the optical axis of a microlens, first and second focus detection pixels for receiving pupil-divided light through a first and second opening offset in first and second directions from the optical axis of a microlens, respectively; ROM for storing shading correction data; correction coefficient generation unit for generating shading correction coefficients respectively for the imaging pixel, and the first and second focus detection pixels from the shading correction data; and correction unit for subjecting a signal for the imaging pixel to shading correction with the use of the shading correction coefficient for the imaging pixel, and subjecting signals for the first and second focus detection pixels to shading correction with the use of the shading correction coefficients for the first and second focus detection pixels.
