专利汇可以提供Compressed parallax photography专利检索，专利查询，专利分析的服务。并且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.，下面是Compressed parallax photography专利的具体信息内容。
1. A traversing camera arrangement for parallax photography comprising: camera means including an objective lens means, a shutter mechanism, an optical screen means having a plurality of focusing elements thereon, and film means disposed behind said optical screen means; excursion means for said camera means for moving said camera means along an arcuate excursion path about an object to be photographed; push means for effecting relative displacement between said film means and said optical screen means; shutter control means for opening and closing said shutter mechanism; timing control means operable when said camera means is moving along said arcuate excursion path for periodically and synchronously actuating said shutter control means and said push means, said timing control means actuating said shutter control means and said push means only at selected sampling periods throughout the excursion path of said camera means, the relative movement between said film means and said optical screen means being in a direction opposite to the direction of camera means movement along said excursion path; synchronizing means for synchronizing and regulating said timing control means and said excursion means with respect to one another, the summation of each relative displacement between said film means and said optical screen means throughout the entire excursion path of said camera means being substantially equal to the width of one focusing element on said optical screen means; and a magnetic brake means for disabling and restraining operation of said push means between said selected sampling periods.
