摘要： PROBLEM TO BE SOLVED: To provide coding and decoding technology in which an unpleasant quantization distortion is suppressed to a prescribed level, so as to reduce a loop back disturbance due to an interruption of a transformation coefficient. SOLUTION: A code amount control circuit 109 obtains a quantization parameter Q proportionate to a buffer sufficiency amount D and a coefficient discontinuation parameter L inversely proportional to the square of the quantization parameter Q. A characteristic of low-frequency transmission processing of a pre-filter 101 is changed so that a gain of a frequency component corresponding to a transformation coefficient yn discontinued, based on the coefficient discontinuation parameter L is zero. Therefore, while avoiding a deterioration of compression efficiency, a loop back disturbance is avoided.

摘要： PURPOSE:To obtain the time space picture filter in which unnatural disturbance such a double image is not caused by controlling a characteristic of a spatial filter with a compression ratio of a picture to execute spatial frequency limit or emphasis for a picture signal. CONSTITUTION:A frame memory 10 delays an input picture signal by one frame period and gives a signal of an existing frame and a signal of one preceding frame to a motion vector detection circuit 20. The motion vector detection circuit 20 adopts the so-called block matching method to obtain a local moving quantity of a picture. A coefficient generating circuit 30 controls coefficients k0-k3 based on a compression ratio of the coding of a picture signal and a horizontal component vx of the moving quantity of the motion vector detection circuit 20. The coefficients k0-d3 are given to variable coefficient circuits 40-43 forming an adaptive horizontal filter 200 and the adaptive horizontal filter 200 controls a high frequency component of the picture signal so that it is stepwise attenuated as the coding compression ratio gets lower and the motion quantity gets larger.
