Abstract
Abstract A color micro optic apparatus which employs black and white photographic film in taking and yet produces color images upon readout. Distributed sets of contiguous color filters, each set having (for example) red, green, and blue filters, are sequentially aligned with corresponding sets of lensettes of microfiche. In use as a camera, red light activates only those emulsion portions of the microfiche which are beneath the red filters, similar discrimination occurring with the blue and green filters. After the emulsion is developed only those emulsion areas beneath filters which have passed light are transparent. For readout, the developed emulsion and filters receive white light (in the opposite direction) to reconstruct a color image.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
201 words
A micro optic apparatus for recording micro images to yield three-dimensional color scenes upon projection, said apparatus including, a. a lensfiche, said lensfiche defined by a transparent sheet having a plurality of interspaced lensettes on its top surface thereof and a photographic emulsion on its bottom surface, b. first and second masks positioned adjacent the top of said lensfiche, and parallel thereto, c. said first mask having a plurality of duplicate sets of color filters spaced over its surface, each of said duplicate color filter sets defined by a plurality of color filters, d. each color filter adapted to be optically aligned with a single lensette, e. the number of color filters in each color filter set multiplied by the number of duplicate color filter sets being less than the number of lensettes, f. said duplicate color filter sets being movable parallel to said lensfiche, whereby such movement aligns the color filters with different sets of lensettes, g. said second mask having a plurality of distributed slots therein and being movable relative to said first mask, said slots being alternately aligned with one set of said duplicate sets and blocked out the other set of said duplicate sets, and vice versa.
Claim 2
Dependent Claim
201 words
A micro optic apparatus for recording micro images to yield three-dimensional color scenes upon projection, said apparatus including, a. a lensfiche, said lensfiche defined by a transparent sheet having a plurality of interspaced lensettes on its top surface thereof and a photographic emulsion on its bottom surface, b. first and second masks positioned adjacent the top of said lensfiche, and parallel thereto, c. said first mask having a plurality of duplicate sets of color filters spaced over its surface, each of said duplicate color filter sets defined by a plurality of color filters, d. each color filter adapted to be optically aligned with a single lensette, e. the number of color filters in each color filter set multiplied by the number of duplicate color filter sets being less than the number of lensettes, f. said duplicate color filter sets being movable parallel to said lensfiche, whereby such movement aligns the color filters with different sets of lensettes, g. said second mask having a plurality of distributed slots therein and being movable relative to said first mask, said slots being alternately aligned with one set of said duplicate sets and blocked out the other set of said duplicate sets, and vice versa.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 including, a. an opaque film on the top of said lensfiche covering the interlensette surface thereof.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1 wherein the color filters of each set of said duplicate sets are for a different color, and are the same for all sets of said duplicate sets.
Claim 5
Dependent Claim
28 words
The apparatus of claim 3 wherein the color filter of all sets are arrayed in the same manner, and wherein said sets and said duplicate sets are contiguous.
Claim 6
Dependent Claim
190 words
A micro optic apparatus for recording micro images to yield three-dimensional color scenes upon projection, said apparatus including, a. a lensfiche, said lensfiche defined by a transparent sheet having a plurality of interspaced lensettes on its top surface thereof and a photographic emulsion on its bottom surface, b. a mask positioned adjacent the top of said lensfiche and parallel thereto, c. said mask having a plurality of sets of slots distributed over its surface, d. a plurality of color filters carried by said lensfiche, said filters being arranged in duplicate sets, each set containing a plurality of color filters, each of said slots having an outline corresponding to the outline of each of said color filter sets, e. each color filter optically aligned with a single lensette, f. the number of color filters in each color filter set multiplied by the number of color filter sets being less than the number of lensettes, g. said mask being alternately movable from one position where said slots are Aligned with one set of said duplicate sets, and another position where said slots are aligned with the other set of said duplicate sets.
Claim 7
Dependent Claim
190 words
A micro optic apparatus for recording micro images to yield three-dimensional color scenes upon projection, said apparatus including, a. a lensfiche, said lensfiche defined by a transparent sheet having a plurality of interspaced lensettes on its top surface thereof and a photographic emulsion on its bottom surface, b. a mask positioned adjacent the top of said lensfiche and parallel thereto, c. said mask having a plurality of sets of slots distributed over its surface, d. a plurality of color filters carried by said lensfiche, said filters being arranged in duplicate sets, each set containing a plurality of color filters, each of said slots having an outline corresponding to the outline of each of said color filter sets, e. each color filter optically aligned with a single lensette, f. the number of color filters in each color filter set multiplied by the number of color filter sets being less than the number of lensettes, g. said mask being alternately movable from one position where said slots are Aligned with one set of said duplicate sets, and another position where said slots are aligned with the other set of said duplicate sets.
Claim 8
Dependent Claim
14 words
The apparatus of claim 5 wherein said color filters are coated on said lensettes.
Claim 9
Dependent Claim
14 words
The apparatus of claim 5 wherein said color filters are positioned beneath said lensettes.
Claim 10
Dependent Claim
21 words
The apparatus of claim 5 including, a. an opaque film on the top of said lensfiche covering the interlensette surface thereof.
Claim 11
Dependent Claim
21 words
The apparatus of claim 6 including, a. an opaque film on the top of said lensfiche covering the interlensette surface thereof.
Claim 12
Dependent Claim
64 words
The apparatus of claim 1 wherein the lensettes corresponding to and associated with each set of color filters are not all of the same radii of curvature, to thereby compensate for variation in refractive index with variation of wavelength, the radii of the lensettes being such that all wavelengths of color light passing through the lensettes towards said emulsion are focused on said emulsion.
Claim 13
Dependent Claim
64 words
The apparatus of claim 5 wherein the lensettes corresponding to and associated with each set of color filters are not all of the same radii of curvature, to thereby compensate for variation in refractive index with variation of wavelength, the radii of the lensettes being such that all wavelengths of color light passing through the lensettes towards said emulsion are focused on said emulsion.
Claim 14
Dependent Claim
64 words
The apparatus of claim 2 wherein the lensettes corresponding to and associated with each set of color filters are not all of the same radii of curvature, to thereby compensate for variation in refractive index with variation of wavelength, the radii of the lensettes being such that all wavelengths of color light passing through the lensettes towards said emulsion are focused on said emulsion.
Claim 15
