Abstract
When distribution image data indicating a defocus distribution is generated from a plurality of sets of image data including pupil-divided image data that is captured image data corresponding to part of an exit pupil, reduced image data is used. Further, based on the distribution image data, pixel data that is to be subjected to the image processing is extracted from the pupil-divided image data corresponding to the distribution image data. The extracted pixel data, the defocus distribution image data, and captured image data corresponding to the entirety of the exit pupil are recorded or output to an external device.
