Three-dimensional color photographic process, apparatus and product

Claim 2

In a stereo color picture, a carrier sheet having photographically recorded thereon a composite image having a balanced, single, sharply focused, a-curate color image of objects from an object plane of interest and laterally displayed stereoscopically related color images of objects corresponding to fforeground and background planes, said stereoscopically related color images being of mutually exclusive but complementary colors.

Claim 3

Apparatus for making stereo pictures, comprising: a lens having an aperture stop, filter, and image receiving medium disposed to receive a focused image of a particular plane of interest from an object space, means dividing the plane of the aperture stop into mutually exclusive left and right segments, including a filter disposed over the left segment at the aperture stop plane to eliminate a first predetermined portion of the spectrum, and a second filter positioned in the right segment of the aperture stop plane to eliminate a second predetermined portion of the spectrum, said portions of the spectrum selected to be mutually exclusive and further selected to contain equal spectral content having approximately equal brightness on the human eye so that rays from an object in the plane of interest and object space are divided into two groups at said aperture stop plane and converged into coincidence and focused in the plane of the image receiving medium to form a composite image having a balanced, single, sharply focused, accurate color image of objects from said plane of interest and laterally displaced, stereoscopically related color images of objects in all other planes from said object space.

Claim 4

Apparatus for making stereo pictures, comprising: a lens having an aperture stop, filter, and image receiving medium disposed to receive a focused image of a particular plane of interest from an object space, means dividing the plane of the aperture stop into mutually exclusive left and right segments, including a filter disposed over the left segment at the aperture stop plane to eliminate a first predetermined portion of the spectrum, and a second filter positioned in the right segment of the aperture stop plane to eliminate a second predetermined portion of the spectrum, said portions of the spectrum selected to be mutually exclusive and further selected to contain equal spectral content having approximately equal brightness on the human eye so that rays from an object in the plane of interest and object space are divided into two groups at said aperture stop plane and converged into coincidence and focused in the plane of the image receiving medium to form a composite image having a balanced, single, sharply focused, accurate color image of objects from said plane of interest and laterally displaced, stereoscopically related color images of objects in all other planes from said object space.

Claim 5

Apparatus as in claim 2 including means for blocking out a significant percentage of the rays passing through the upper and lower extremes of the aperture stop thereby reduce upper and lower edgewise blur whereby lateral image edges fused in the mind of the viewer yield an impression of overall sharpness of image since lateral fusion can take place in the viewer''s mind and upper and lower blur is eliminated by the blocking means.

Claim 6

Apparatus as in claim 3 in which said blocking means comprises an opaque stop having portions throughout regions consisting of upper and lower wedges symmetrically disposed about vertical and horizontal lines interesting the center of said aperture stop.

Claim 7

Apparatus as in claim 3 in which said blocking means is opaque over the uppermost and lowermost areas of the aperture stop.

Claim 8

Apparatus as in claim 3 wherein said blocking means blocks all areas of said stop except for horizontally spaced apart and symmetrically disposed openings on which said filters are disposed.

Claim 9

Apparatus as in claim 5 wherein said openings are circular and have center to center spacing of about 1/2 the diametral dimension of said aperture stop.
