    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.
