ABSTRACT:
A microprocessor control controls the operation of a color video printer to produce color photographic copies from color video images. The printer includes a monochrome cathode ray tube (CRT) and an exposure station which is located along an optical path from the CRT and at which is positioned self-processing photographic elements. A video signal circuit provides a color video signal constituting frames of interlaced odd and even fields repeated at broadcast field frequency, wherein each field includes three concurrent color component video signals respectively representing first, second and third colors of a field image. A rotatable filter has red (R), green (G), and blue (B) filters sequentially movable into the optical path. The rotation of the filter is synchronized by the microprocessor control with the field frequency of the color video signal. The microprocessor control actuates a gate connected between the video signal circuit and the CRT to expose a photographic element positioned at the exposure station to a sequence of six color field images corresponding to a full resolution color frame image. The microprocessor control also inhibits exposure of the photographic element when the filter wheel is not rotated in synchronism with the field frequency of the color video signal.
