An Instantaneous Electronic Color-Film Analyzer

Bernard D. Loughlin, Charles E. Page, William F. Bailey, Charles J. Hirsch, Arthur J. Miller, Leonard Giarraputo

The Analyzer for negative, or positive, color original film displays instantaneously a positive color picture on a color TV tube when a color original is inserted in the device. Color balance and density are adjusted by calibrated controls whose settings are used by a printer to produce a positive closely approximating the displayed picture. The device uses TV techniques to simulate additively the subtractive properties of positive film in spectral taking sensitivities, gamma, contrast and unwanted dye absorptions.
