Abstract
Digital video effects equipment for providing special effects by controlling the number of quantization levels for each sample of an incoming television video signal. Each video signal sample is converted into a digital signal comprising a predetermined number of binary digits. A gradation modification circuit decreases the gradation represented by the digitized video signal and the decreased gradation signal is reconverted to an analog signal. The resultant special effects gives the video picture an oil-painting-like impression.
