Abstract
Abstract An apparatus for use as both a camera and a viewer. As a camera, light from an object is broken up by a planar array of N lenses into N identical images which fall onto an opaque mask. A small aperture lies within each image, but at a different relative zone so that the apertures are non-homologous with respect to the image. Light passing through the apertures strikes virgin photographic emulsion of a lensfiche. The lensfiche is indexed and the process repeated for the next object. After emulsion development, the lensfiche is sequentially illuminated from the rear and each object (macroscene) sequentially reconstructed by projection on a viewing screen. For one embodiment, the method of recording consists of forming N identical and non-overlapping images, taking one portion from each of the N images, the N portions being non-homologous and dispersed from each other, and photographically recording N non-homologous portions. For readout, the N portions are projected and magnified on a screen to reconstitute the original object, the N portions now coalesced to form a coherent, non-dispersed image.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A combination projector and camera projection apparatus including, a. a generally planar array of objective lenses, b. an opaque scene mask, said mask being at a distance from said lenses equal to the image distance of said lenses, c. septa extending from said objective lenses to said scene mask, said septa defining cells, the septa forming with their intersection with said scene mask a plurality of identical zones on said scene mask, each zone corresponding to a single lens of the array, d. said scene mask having apertures, there being an aperture for and corresponding to each of said objective lenses and to each of said zones, the optic axis of each objective lens intersecting a corresponding, single one of said zones on said scene mask, the apertures of said scene mask being non-homologously positioned with respect to the said zones of the scene mask so that no two apertures of said scene mask have the same homologous position in their respective zones.
Claim 2
Dependent Claim
163 words
A combination projector and camera projection apparatus including, a. a generally planar array of objective lenses, b. an opaque scene mask, said mask being at a distance from said lenses equal to the image distance of said lenses, c. septa extending from said objective lenses to said scene mask, said septa defining cells, the septa forming with their intersection with said scene mask a plurality of identical zones on said scene mask, each zone corresponding to a single lens of the array, d. said scene mask having apertures, there being an aperture for and corresponding to each of said objective lenses and to each of said zones, the optic axis of each objective lens intersecting a corresponding, single one of said zones on said scene mask, the apertures of said scene mask being non-homologously positioned with respect to the said zones of the scene mask so that no two apertures of said scene mask have the same homologous position in their respective zones.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 wherein the intersection of the optic axis of each objective lens with its corresponding zone on said scene mask is at the center of the zone.
Claim 4
Dependent Claim
39 words
The apparatus of claim 1 wherein the intersection of the optic axis of each objective lens with its corresponding zone on said scene mask is at the center of the said aperture corresponding to and positioned within each zone.
Claim 5
Dependent Claim
127 words
The apparatus of claim 1 including, a. a lensfiche having a photographic emulsion on one side thereof and a plurality of integral lensettes on the other side thereof, opaque portions extending around said lensettes to form aperture stops for said lensettes, said lensfiche being parallel to and contiguous to said scene mask, said scene mask positioned between said lensfiche and said lens array, b. a second opaque mask overlying and parallel to said lensettes, said second mask having openings, said openings being larger than the said lensette aperture stops, there being a corresponding second mask opening for each said lens of said objective lens array, c. a light-scattering viewing screen parallel to and spaced from said lensfiche a distance equal to the image distance of said lensettes.
Claim 6
Dependent Claim
15 words
The apparatus of claim 1 wherein the optic axes of said objective lenses are parallel.
Claim 7
Dependent Claim
28 words
The apparatus of claim 1 wherein the optic axes of said objective lenses diverge from an imaginary point on the same side of the lenses as said septa.
Claim 8
Dependent Claim
16 words
The apparatus of claim 6 wherein the centers of said lenses lie on a common plane.
Claim 9
Dependent Claim
26 words
The apparatus of claim 6 including a light refracting prism covering each opening of said scene mask and being on the side thereof adjacent said septa.
