APPARATUS FOR BAND COMPRESSION PROCESSING OF A PICTURE SIGNAL

摘要

An apparatus for band compression processing of a picture signal which generates forecasting error signal and movement vector and updates only the movement vector during a comb-out operation. During comb-out processing, a picture signal is recirculated while the movement vector is produced and accumulated. At the end of the comb-out processing, the change in the movement vector from the accumulated vector is within a desired range. Therefore, a scale of circuit does not increase for detecting the movement vector after the comb-out operation.
