Abstract: A printer control unit utilizes a microprocessor and a random-access memory for storing color and cuing information in order to eliminate the need for continuously reading a tape during the printing operation. The printer control unit utilizes a single tape reader and the microprocessor is programmed to permit color tapes, cuing tapes or composite tapes to be read by the single tape reader.

Abstract: A control unit for a photographic film printer for printing motion picture film onto raw stock from a master preprint film. The operation of various functions of the printer such as color changes, fades, and the like, are controlled in accordance with a control tape bearing information for the control of the various components. Various cue signals indicating where the desired controls are to be effective during the printing process are provided by a notch or RF patch system, a separate frame counting system utilizing a separate film address information tape, or an integral frame counting cuing system wherein the film address information is provided on the same control tape with the control information.

Abstract: A programmable exposure control device for use on a photographic film printer for producing special effects in motion pictures such as a fade-in, fade-out, lap dissolve or other numerous special effects requiring variations in printing beam intensity. The exposure control device comprises a mechanical shutter capable of progressively varying the intensity of the printing beam at any predetermined rate. A control system is provided for operating the shutter and includes a memory portion for storing preselected operating curves for a plurality of film exposure characteristics. The control unit is connected to a tape reader for supplying information to the control unit, for example, relating to the length of the particular fade desired. The tape reader also may provide information for controlling the position at which a fade or other special effect is to begin or end.
