Abstract
Abstract Camera apparatus for securing three dimensional photographic images wherein equivalent relative displace-ment between the subject to be photographed and the camera to effect deposition of a continuous series of images on a photosensitive film through a multiple-element lens overlay adjacent thereto is optically effected by interposition of displaceable light reflecting means intermediate the camera and subject and a photo-sensitive film construction wherein the photosensitive emulsion is integrally superposed on a multielement lens overlay of selectively variable character.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
170 words
An apparatus for taking relief photographs of a subject on a photosensitive film comprising mirror means, means for displacing said mirror means along an eliptical path means for rotating said mirror means as said mirror means is displaced along the eliptical path so that an image of a subject located at one focal point of the elipse will be reflected to the other focal point thereof, camera means located at one of the focal points of the elipse and incorporating a multi-element lens array disposed closely adjacent a photosensitive film and means for effecting exposure of a continuous time sequenced series of images of a subject located at the other focal point of the elipse in the plane of said photosensitive film under each lens element of said array, and means for selectively rotating said camera means about said one focal point for receiving the image of the subject located at the other focal point reflected by said mirror means as said mirror means is displaced along the eliptical path.
Claim 2
Independent Claim
170 words
An apparatus for taking relief photographs of a subject on a photosensitive film comprising mirror means, means for displacing said mirror means along an eliptical path means for rotating said mirror means as said mirror means is displaced along the eliptical path so that an image of a subject located at one focal point of the elipse will be reflected to the other focal point thereof, camera means located at one of the focal points of the elipse and incorporating a multi-element lens array disposed closely adjacent a photosensitive film and means for effecting exposure of a continuous time sequenced series of images of a subject located at the other focal point of the elipse in the plane of said photosensitive film under each lens element of said array, and means for selectively rotating said camera means about said one focal point for receiving the image of the subject located at the other focal point reflected by said mirror means as said mirror means is displaced along the eliptical path.
Claim 3
Dependent Claim
39 words
An apparatus for taking relief photographs according to claim 1 further comprising means for maintaining the optical axis of said camera means coincident the point of tangency between said mirror means and its eliptical path during its displacement therealong.
