Although geometric information is distorted when a picture’s viewing point is changed, it has been anecdotally reported that such distortions do not affect perception. Two experiments assessed pictorial constancy relative to the distortions introduced by viewing point dislocation. Results provide the first psychophysical demonstration of pictorial constancy, and indicate that constancy is based on the discrepancy between the actual and the assumed correct viewing position. An explanation of pictorial constancy is offered which can be applied to direct picture perception and to picture-in-a-picture perception.
