Abstract
Abstract A method and apparatus is disclosed which utilizes a novel compressed parallax photographic technique to create pictorial parallax panoramagrams having an illusion of depth. A traversing camera having an objective lens means and an optically transparent lenticular screen disposed above the film is caused to traverse an arcuate path about the object to be photographed. The arcuate excursion distance is greatly enlarged over the distances utilized in prior art techniques and the camera, rather than continuously photographing the object throughout the arcuate excursion, photographs the object only at sampled locations along its arc of excursion. The film in the camera is advanced only when the camera is taking a photographic sample. The inventive technique is such that a much greater degree of parallax can be obtained without any loss of resolution and fidelity of the photographic image.
