ABSTRACT:
Video signals from pre-recorded video tape or a video camera are received by the present invention and processed to provide the appearance of a motion picture film recorded image. The output of the invention may be provided directly for television broadcast or recording on video tape. Simulation of film frames is provided by summing a real time signal and delayed signals to create an interpolation of preceding and succeeding video fields. Addition of mixed, clipped and filtered noise to provide the appearance of grain in photographic film and alteration of the apparent contrast provide variable artistic attributes which are adjustable for the desired film appearance.
