An image processing apparatus calculates a near image distance, corresponding to a distance from a virtual viewpoint to a first viewpoint among viewpoints of a plurality of images, and a far image distance, corresponding to a distance from the virtual viewpoint to a second viewpoint among the viewpoints of the plurality of images, which is relatively distant from the virtual viewpoint compared with the first viewpoint, sets a search range, determines parallax vectors corresponding to search reference block coordinates by executing block matching processing within the search range and by using a first block image, included in a near image and corresponding to the search reference block coordinates and the near image distance, and a second block image, included in a far image and corresponding to the search reference block coordinates and the far image distance, and generates an image viewed from the virtual viewpoint by using the parallax vectors.
