Abstract
An image processing apparatus for processing image signals output from an image sensor having a plurality of unit cells each including a plurality of photoelectric conversion elements for receiving light passing through different pupil regions and each of which can be read out separately, wherein: a detection unit detects a phase difference between a plurality of images each formed on the basis of image signals of photoelectric conversion elements located in a same position in each of the plurality of unit cells; a determination unit determines a defective photoelectric conversion element; and a correction unit corrects a defective image signal of a defective photoelectric conversion element using an image signal corresponding to the defective image signal and constituting another of the plurality of images that does not include the defective image signal, based on the phase difference detected by the detection unit.
