  • Video encoding method and apparatus based on human visual sensitivity
    Patent number: 5847766
    Abstract: A video encoding method and apparatus classifies a video signal based on human visual sensitivity and determines a reference quantization step size for each classification. To determine the quantization step size for a given transmission speed in consideration of a video signal distribution characteristic, a video encoding apparatus adaptively allocates a target bit number, obtains a final quantization step size by adjusting the reference quantization step size, and encodes the video signal through utilization of the final quantization step size. Thus, the compression effect of an input video signal is increased and the picture quality of the restored image is improved.
