Abstract
A video encoder for reducing the deterioration of picture quality of a compress coded video signal by implementing a method for deciding the number of picture elements needed to properly encode an inputted video signal. The decision is calculated based on the difficulty of compressing the inputted video signal and the number of picture elements needed to accurately reproduce a compressed inputted video signal. The decision circuitry decides the number of picture elements needed for compression of the inputted video signal allowing the number of codes generated in the encoding process to be decreased and quantization accuracy improved. The main advantage is a reduction in deterioration of the video signal usually found when reproducing a compress coded video signal.
