  • Color television film scanning system using uniform motion and line arrays
    Patent number: 4310847
    Abstract: A color image is recorded on film at the television field rate. A portion of the film is illuminated, corresponding to a line in the color image, and decomposed into its component colors. The decomposed light from the line is imaged onto two or more line scanning photosensitive arrays which provide scanned signals. These scanned signals are decoded and used to provide the standard color television signals.
