Claim One:
1. An image processing apparatus comprising: an image acquisition unit configured to acquire a captured image obtained by imaging at least one of a projection surface onto which an image is projected so that the optical axis of projected light projected from a projection device and the projection surface form an acute angle and a perimeter of the projection surface; a shadow detection unit configured to detect, based on the captured image, a shadow produced by an object entering the optical path of the projected light on at least one of the projection surface and the perimeter of the projection surface; a pointed position determination unit configured to determine, based on the detected shadow, a position that differs from the position of the shadow on the projection surface and that has a predetermined relation with the position of the shadow to be a pointed position pointed by a user; and a pointing information output unit configured to output information corresponding to the determined pointed position.
