Abstract
Abstract This invention is a camera for use in making true color photographs which is especially useful in aerial and space photography applications. In accordance with the invention, the camera provides a gray scale reference image for each scene photographed. This reference image is exposed on an edge of the film by means of a light characteristic reference image negative disposed in close proximity to the film surface and fiber optic light transmission means which transmits light energy to the negative such that the edge of the film is exposed through the reference negative. Edge disposition of the reference image enables automatic processing of true color prints from the negative. The reference image may be made with a light source located in or near the camera and/or with light from the natural or artificial scene-illuminating source. A spot representing the density of the scene being photographed may be exposed adjacent to the one or two gray scale images by light passing through the camera lens and an internal lens system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A color data acquisition camera having a principal lens system adapted to produce a framed record of an event on a photosensitive color film surface comprising a principal lens system adapted to expose a framed first segment area on said photosensitive film and a light characteristic reference image means adapted to produce a light characteristic reference image upon a second segment area of said photosensitive film coadjacent one edge of said framed first segment area, said reference image means being a color reference means of the gray scale reference variety, said reference image means including a light characteristic reference image negative disposed in close proximity and in parallel relation to said second segment area of said phOtosensitive film and means for exposing said second segment area through said reference image negative coincident in time with exposure of said first segment area, said means for exposing said second segment area including an artificial light source internally disposed within said camera and light transmission path means adapted to conduct the light output thereof to said color reference image means.
Claim 2
