Abstract

A motion detecting and motion compensative prediction circuit includes an integer pixel accuracy calculating unit for carrying out calculation for detecting, with an integer pixel accuracy, a portion most approximate to an object of a current frame from a predetermined reference frame, and a half pixel accuracy calculating and motion compensative prediction unit (including a buffer memory, a re-arranging unit for rearranging a picture data supplied thereto through the buffer memory by a pixel unit, and an interpolation unit for subjecting the picture data re-arranged by the re-arranging unit to linear interpolation calculation). The buffer memory, the re-arranging unit and the interpolation means of the half-pixel accuracy calculating and motion compensative prediction unit are commonly employed both of a processing for detecting a half-pixel accuracy motion vector based on the calculation result of the integer pixel accuracy calculating unit and a processing for generating a predictive-coded picture by using the motion vector.
