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: 20
Claim 1
Independent Claim 148 words
A micro optic apparatus for recording or for reading out micro images in color, 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 color filters spaced over its surface, each color filter set defined by a plurality of single-color, 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 color filter sets being less than the number of lensettes, f. said color filter sets being movable parallel to said lensfiche, whereby such movement aligns the color filters with different sets of lensettes.
Claim 2
Dependent Claim 148 words
A micro optic apparatus for recording or for reading out micro images in color, 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 color filters spaced over its surface, each color filter set defined by a plurality of single-color, 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 color filter sets being less than the number of lensettes, f. said color filter sets being movable parallel to said lensfiche, whereby such movement aligns the color filters with different sets of lensettes.
Claim 3
Dependent Claim 21 words
The apparatus of claim 1 including, a. an opaque coating on the top of said lensfiche covering the interlensette surface thereof.
Claim 4
Dependent Claim 39 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 retractive index with variation of wavelength.
Claim 5
Dependent Claim 39 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 retractive index with variation of wavelength.
Claim 6
Dependent Claim 163 words
A micro optic apparatus for recording or for reading out micro images in color, 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 plurality of sets of color filters the filters of each set arranged among themselves in a pattern, c. an opaque mask having a plurality of through aperture sets distributed thereover, each aperture set having an outline corresponding to the pattern of each color filter set, said mask positioned to overlie the top of said lensfiche, said mask and lensfiche being relatively movable so that the mask apertures are, successively, aligned with different sets of lensettes upon such relative motion, the number of sets of mask apertures multiplied by the number of apertures in each aperture set being less than the number of lensettes, d. each color filter being in optical alignment with a single lensette.
Claim 7
Dependent Claim 163 words
A micro optic apparatus for recording or for reading out micro images in color, 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 plurality of sets of color filters the filters of each set arranged among themselves in a pattern, c. an opaque mask having a plurality of through aperture sets distributed thereover, each aperture set having an outline corresponding to the pattern of each color filter set, said mask positioned to overlie the top of said lensfiche, said mask and lensfiche being relatively movable so that the mask apertures are, successively, aligned with different sets of lensettes upon such relative motion, the number of sets of mask apertures multiplied by the number of apertures in each aperture set being less than the number of lensettes, d. each color filter being in optical alignment with a single lensette.
Claim 8
Dependent Claim 21 words
The apparatus of claim 5 including, a. an opaque coating on the top of said lensfiche covering the interlensette surface thereof.
Claim 9
Dependent Claim 14 words
The apparatus of claim 5 wherein said color filters are coated on said lensettes.
Claim 10
Dependent Claim 15 words
The apparatus of claim 5 wherein said color filters are carried by said opaque mask.
Claim 11
Dependent Claim 14 words
The apparatus of claim 5 wherein said color filters are positioned beneath said lensettes.
Claim 12
Dependent Claim 21 words
The apparatus of claim 7 including, a. an opaque coating on the top of said lensfiche covering the interlensette surface thereof.
Claim 13
Dependent Claim 21 words
The apparatus of claim 8 including, a. an opaque coating on the top of said lensfiche covering the interlensette surface thereof.
Claim 14
Dependent Claim 21 words
The apparatus of claim 9 including, a. an opaque coating on the top of said lensfiche covering the interlensette surface thereof.
Claim 15
Dependent Claim 39 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 retractive index with variation of wavelength.
Claim 16
Dependent Claim 39 words
The apparatus of claim 6 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 retractive index with variation of wavelength.
Claim 17
Independent Claim 84 words
A method of color recording macro scenes on a microfiche which carries a plurality of lensettes and which is provided with a photographic emulsion beneath said lensettes, including the steps of: a. projecting a macro scene through distributed sets of laterally spaced color filters, each color set having a plurality of color filters, each color filter being in optical alignment with a single lensette, the number of color filters times the number of color filter sets being less than the total number of lensettes.
Claim 18
Independent Claim 84 words
A method of color recording macro scenes on a microfiche which carries a plurality of lensettes and which is provided with a photographic emulsion beneath said lensettes, including the steps of: a. projecting a macro scene through distributed sets of laterally spaced color filters, each color set having a plurality of color filters, each color filter being in optical alignment with a single lensette, the number of color filters times the number of color filter sets being less than the total number of lensettes.

Dependent Claim 52 words
The method of claim 15 including the additional later step of moving said fiche relative to said mask to thereby align a different unique set of lenses with the mask apertures, and then projecting a second macro scene, this additional step being repeated for each different macro scene recorded on the emulsion.
