Abstract
PURPOSE: To prevent the blurred image by coding without controlling the amplitude, by generating the forecasting erroneous signal between frames against the input signal, on which the gain becomes smaller than 1 in case the output amplitude is smaller than the estimated value, and it is passed through non-linear circuit whose gain becomes 1 in case the output amplitude is large, and making the forecast coding in the frame.
