Abstract
An image processing apparatus comprises an acquiring unit configured to acquire pixel signals in which light fluxes from a subject are stored, each pixel signal being such that a pixel has stored a pupil-divided light flux obtained by performing pupil division on the light flux; a determination unit configured to determine, with respect to pixels of the pixel signals that are associated with a predetermined region, whether or not a pixel value of each pixel satisfies a predetermined relationship to a pixel value of a pixel having stored another light flux from the same subject; and a detection unit configured to detect that there is an external factor that varies the pixel value in the predetermined region if the pixels of the pixel signals include a predetermined number or more of pixels that are determined to satisfy the predetermined relationship.
