An image processing apparatus obtains an image signal of an image pickup element having a pupil division unit that restricts light of an optical image of an object arriving at each pixel of the element to light from a specific pupil area of a photographing lens. A memory unit stores information of a pixel defect of the element. An image shift unit determines a shift amount of the image signal of the photographed object corresponding to an image re-formation plane for every pupil area, to shift the image signal on the basis of the plane. A defect correction unit corrects an image signal of a defective pixel using the shifted image signal of a pixel other than the defective pixel, in accordance with the information of the pixel defect. An image re-formation unit re-forms an image corresponding to the image re-formation plane from the corrected image signal. |
