Abstract
Abstract Photographic printing method and apparatus for converting abnormal, reversed or pseudoscopic three-dimensional photographic images to normal images concurrently with the printing thereof in desired size relation through interposition use of multielement lens overlays to effect selective optical inversion of component image elements and exposure of photosensitive film to such inverted relief data images.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
Apparatus for reproducing relief photographs constituted by a sheet of film having a plurality of elongated relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph, at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said photograph with the individual lens elements thereof being disposed in respective longitudinal alignment with said relief data strips thereon said multielement lens overlay including optical barrier means disposed intermediate each lens element thereof, and a photosensitive film disposed in static adjacent relation to said overlay and exposable to said inverted images of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in natural orientation.
Claim 2
Dependent Claim
141 words
Apparatus for reproducing relief photographs constituted by a sheet of film having a plurality of elongated relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph, at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said photograph with the individual lens elements thereof being disposed in respective longitudinal alignment with said relief data strips thereon said multielement lens overlay including optical barrier means disposed intermediate each lens element thereof, and a photosensitive film disposed in static adjacent relation to said overlay and exposable to said inverted images of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in natural orientation.
Claim 3
Dependent Claim
143 words
Apparatus for reproducing relief photographs constituted by a sheet of film having a plurality of elongated relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph, at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said abnormal photograph with the individual lens elements thereof being disposed in respective longitudinal alignment with said relief data strips thereon, a photosensitive film disposed in static adjacent relation to said overlay and exposable to said inverted image of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in normal orientation, and a second multielement lens overlay disposed intermediate said first mentioned lens overlay and said photograph.
Claim 4
Dependent Claim
143 words
Apparatus for reproducing relief photographs constituted by a sheet of film having a plurality of elongated relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph, at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said abnormal photograph with the individual lens elements thereof being disposed in respective longitudinal alignment with said relief data strips thereon, a photosensitive film disposed in static adjacent relation to said overlay and exposable to said inverted image of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in normal orientation, and a second multielement lens overlay disposed intermediate said first mentioned lens overlay and said photograph.
Claim 5
Dependent Claim
156 words
Apparatus for reproducing relief photograph constituted by a sheet of film having a plurality of elongate relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph including an auxiliary collimating lens disposed closely adjacent to said film and an extended area light source disposed remote from said collimating lens at its focal distance and at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said photograph with the individual lens lements thereof being disposed in respective longitudinal alignment with said relief data strips thereon and a photosensitive film disposed in static predetermined spaced relation to said overlay and exposable to said inverted images of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in normal orientation.
Claim 6
Dependent Claim
156 words
Apparatus for reproducing relief photograph constituted by a sheet of film having a plurality of elongate relief data strips each containing a continuous sequence of relief image data in reverse orientation thereon comprising illumination means disposed on one side of said photograph including an auxiliary collimating lens disposed closely adjacent to said film and an extended area light source disposed remote from said collimating lens at its focal distance and at least one multi-element lens overlay disposed in predetermined spaced relationship with the other side of said photograph with the individual lens lements thereof being disposed in respective longitudinal alignment with said relief data strips thereon and a photosensitive film disposed in static predetermined spaced relation to said overlay and exposable to said inverted images of each such sequence of relief image data on each said data strip produced by the lens elements of said lens overlay to reproduce said relief image data in normal orientation.
Claim 7
Dependent Claim
23 words
Apparatus as set forth in claim 3 including a third multielement lens array disposed intermediate said auxiliary collimating lens and said abnormal film.
