Abstract:
A color correction system for use in correcting the look of a motion picture film scene comprisinga source of illumination, a color control unit for receiving light from the source of illumination, the color control unit having a plurality of light valves for allowing individual colors to be varied and incrementally changed to produce a resulting projection beam having selected color levels, a film projector disposed for receiving the resulting beam, the film projector having a motion picture driving system for feeding the motion picture film through the projector and having an optical system for projecting frames of film onto a viewing screen, a film position encoder for detecting film position, a light valve control interface connected to the color control unit for providing control signals for controlling light values thereof in adjusting color levels thereof, and the interface for receiving position data from the encoder, and a terminal for receiving and storing signals from the interface representative of the color levels selected and film position from the encoder, and for enabling this information to be provided to a motion picture film printer for control of color levels in the printer for printing a subsequent film scene.
