International ClassG06T 015/10AbstractA video special effects system and method includes at least one signal system operating in real time to transform one or more input video signals to generate an output video in response thereto, a work station, an operator control panel and a control system communicating with the signal systems, the work station and the control panel. Control surfaces defined by one or two control curves are developed at the work station and subsequent used by the control system to define a video effect in which portions of the input video images are selectively mapped to the control surfaces and subsequently manipulated to define an output video image. The control system operates to define each parameter controlling the output image at selected event times and to individually interpolate each given parameter between the event times at which the parameter is defined. The signal systems generate the output images in response to input images and the instantaneous values of control parameters defined by the control system.Other References
