Apparatus and method for creating video outputs that emulate the look of motion picture film

Abstract

Video output emulating the broadcast look of motion picture film is created by the present invention. A video camera for real time simulation of the visual appearance of motion picture film that has been transferred or converted to a video signal comprising analog signal input conditioning circuitry, an analog to digital convertor, timing and control circuitry, an address multiplexer and memory control, a digital adder, and a digital to analog convertor. A method for creating the look of broadcast motion picture film comprising the steps of increasing the scan rate of CCD image sensors to output non-interlaced video images, converting said video images from analog to digital form, writing said video images to memory, adding a selective, adjustable amount of two dimensional, electronic artifacts to simulate film grain, reading said video images from said memory banks to a video output data bus at predetermined rates, and converting said video images from digital to analog form for recording or broadcast.
