Abstract
An image processing apparatus comprises: a dividing unit that divides two frame images into a plurality of divided areas; a determination unit that determines a representative point for each of the divided areas in one of the two frame images; a setting unit that, for each of the two frame images, sets image portions for detecting movement between the two frame images, based on the representative points; and a detection unit that detects movement between the two frame images based on correlation values of image signals in the set image portions, wherein for each of the divided areas, the determination unit determines a feature point of the divided area or a predetermined fixed point as the representative point of the divided area in accordance with a position of the divided area in the one frame image.
