Color coding and decoding system for use in micrographics

Claim 1

A color coding and decoding device for use in micrographics including, in combination: a. a camera body; b. a light spectrum dividing means secured in said camera body for splitting the light spectrum from a scene of which a picture is to be taken into first and second different spectral portions; c. first and second lens in said camera receiving said first and second spectral portions; d. a slide member in said camera having negative film holding means for holding first and second black and white film negatives in said camera in positions behind said first and second lens respectively for exposure to spectral bands within said first and second spectral portions, when the slide member is in a first position; and e. projection light means behind said holding means, said holding means also including transparency holders for holding transparencies behind said lens and permitting light to pass from said projection light means through the transparencies when said slide member is moved to a second position, whereby first and second black and white negatives are provided from which positive prints may be made in the form of slide transparencies and subsequently received in said transparency holders for projection back through said lens and said spectrum dividing means onto a screen such that the spectral portions are recombined to produce the original scene.
