Abstract
Abstract An autostereoscopic picture is produced in which the width of the lineiform image bands of the stereo pairs within each lenticule are varied and adjusted to compensate for the visual parallax between the stereo pairs of the 3-D photograph according to the depth of field of each 3-D photograph in order to accommodate the interoccular distance and viewing angle of the eyes to improve the depth-of-field and 3-D effect of each 3-D photograph.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
An image array formed on the photosensitive surface of lenticular print film, said image array consisting of a multiplicity of stereoscopic image pairs of lineiform image bands within each lenticule, with the image bands of each stereoscopic image pair nearest the center of the lenticule having a width substantially different from the image bands of the stereoscopic image pairs farther from the center.
Claim 2
Dependent Claim
63 words
An image array formed on the photosensitive surface of lenticular print film, said image array consisting of a multiplicity of stereoscopic image pairs of lineiform image bands within each lenticule, with the image bands of each stereoscopic image pair nearest the center of the lenticule having a width substantially different from the image bands of the stereoscopic image pairs farther from the center.
Claim 3
Dependent Claim
54 words
The image array of claim 1 in which the image band of each stereoscopic pair is on each side of the center of the lenticule with the image bands of the stereoscopic image pairs nearest the center having a width substantially different from the image bands of the stereoscopic pairs farther from the center.
Claim 4
Dependent Claim
41 words
The image array of claim 2 in which the image bands of the stereoscopic pairs nearest the center of the lenticule have a width substantially greater than the width of the image bands of the stereoscopic pairs farthest from the center.
Claim 5
Dependent Claim
41 words
The image array of claim 2 in which the image bands of the stereoscopic pairs farthest from the center have a width substantially greater than the width of the image bands of the stereoscopic pairs nearest the center of the lenticule.
Claim 6
Dependent Claim
41 words
The image array of claim 3 in which the image bands of the stereoscopic pair nearest the center has a width of from 1.25 to 3 times the width of the bands of the stereoscopic image pair farthest from the center.
Claim 7
Dependent Claim
41 words
The image array of claim 4 in which the image bands of the stereoscopic pair farthest from the center has a width of from 1.25 to 3 times the width of the image bands of the stereoscopic pair nearest the center.
Claim 8
Independent Claim
92 words
A method of forming an image array on the photosensitive surface of the lenticular print film with said image array consisting of a multiplicity of image bands of the stereoscopic pairs within each lenticule, with the image bands of each stereoscopic pair nearest the center of the lenticule having a width substantially different from the image bands of the stereoscopic pairs farthest from the center, which comprises projecting the images on negatives taken from a stereoscopic camera through projecting lenses so that the image bands are of unequal width as indicated above.
Claim 9
Independent Claim
92 words
A method of forming an image array on the photosensitive surface of the lenticular print film with said image array consisting of a multiplicity of image bands of the stereoscopic pairs within each lenticule, with the image bands of each stereoscopic pair nearest the center of the lenticule having a width substantially different from the image bands of the stereoscopic pairs farthest from the center, which comprises projecting the images on negatives taken from a stereoscopic camera through projecting lenses so that the image bands are of unequal width as indicated above.
Claim 10
Dependent Claim
47 words
The method of claim 7 in which there are a plurality of identical images projected side by side in each image band comprises focusing the projecting lens on each image band with each negative so that the images in each image band are in a side-by-side relationship.
Claim 11
Dependent Claim
24 words
The method of claim 7 in which the projecting lens scans each image band and projects a series of images onto each image band.
Claim 12
Dependent Claim
26 words
The method of claim 7 in which the aperture of the projecting lens is adjusted so that a single image is projected onto each image band.
