Abstract
Abstract Three-dimensional photographs are produced in which there are three image bands within each lenticule in which each image band is between 8.5 degrees and 11 degrees in width in order to permit a photograph to be viewed from wider angles so that the eyes will see adjacent stereo pairs from any viewing angle and the picture will be in total focus. A three lens camera is provided to take these photographs.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
31 words
An image array formed on the photosensitive surface of lenticular print film, said image array consisting of two stereoscopic image pairs within a group of three image bands in each lenticule.
Claim 2
Dependent Claim
31 words
An image array formed on the photosensitive surface of lenticular print film, said image array consisting of two stereoscopic image pairs within a group of three image bands in each lenticule.
Claim 3
Dependent Claim
26 words
The image array of claim 1 in which each image band occupies space between approximately 81/2 and 11 degrees of the viewing angle of the lenticule.
Claim 4
Dependent Claim
28 words
The image array of claim 2 in which there is a plurality of identical images of the same two-dimensional view in each image band in a side-by-side relationship.
Claim 5
Dependent Claim
17 words
The image array of claim 2 in which there is a single image in each image band.
Claim 6
Dependent Claim
90 words
A three lens three-dimensional camera in which the lenses are arranged in substantially the same horizontal plane with the distance between adjacent lenses being equal and determined by the focal length of the lenses and size of the negative being utilized so that when the film is projected onto lenticular photographic material so that the image taken through the center lens of the camera is projected onto the photographic material at the center of the lenticule with the images from the other two lenses being projected on each side thereof.
Claim 7
Dependent Claim
