United States Patent 4777102
A method for electronic "dry" development of latent images in conventional types of color photographic films comprising interrogating the film with a series of different color light beams, each corresponding in color frequency with a different color sensitivety of the film and each having a time-amplitude energy content that is sufficient to drive that latent color image in the film into a condition of saturation. Deriving from each of said different color interrogations an electrical signal, corresponding to the latent image in that color, and recording said electrical signals. An apparatus for performing said method comprises a portable, light tight enclosure, containing a series of different color interrogating light beam generating mechanism, light energy detectors, and electrical recorders.
