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 (402), an analog to digital converter (403), timing and control circuitry (404), an address multiplexer and memory control (405), a digital adder (406), and a digital to analog converter (407). A method for creating the look of broadcast motion picture film comprising the steps of increasing the scan rate of image sensors to output non-interlaced video images, converting the video images from analog to digital form, writing the images to memory, adding a selective adjustable amount of two dimensional, electronic artifacts to simulate film grain, reading the video images from memory to a video output data bus at predetermined rates, and converting the video images from digital to analog form for recording or broadcast. <IMAGE> |
