VIDEO SYSTEM FOR SIMULATION OF MOTION PICTURE FILM

摘要

A video camera (1201) is provided for real time simulation of the visual appearance of motion picture film that has been transferred or converted to a video signal. A process is disclosed 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 the video images from analog to digital form, writing the video images to memory (812, 815, 818), adding a selective, adjustable amount of two-dimensional, electronic artifacts to simulate film grain, reading the video images from the memory banks (812, 815, 818) to a video output data bus (806) at predetermined rates, and converting the video images from digital to analog form for recording or broadcast.
