Abstract: An image processing apparatus generates a left-eye viewpoint image and a right-eye viewpoint image, detects one or more pairs that are each a pair of a partial image of the left-eye viewpoint image and a partial image of the right-eye viewpoint image that are similar to each other, performs, for each of the one or more pairs, image adjustment processing for adjusting the three-dimensionality of one of or both of the partial images of the left-eye and right-eye viewpoint images, displays the left-eye viewpoint image or the left-eye viewpoint image after the image adjustment processing in a manner such that this image is capable of being observed with a left eye, and displays the right-eye viewpoint image or the right-eye viewpoint image after the image adjustment processing in a manner such that this image is capable of being observed with a right eye.
