Abstract
A motion vector detecting circuit calculates a residual between the reference block read from a frame memory and retrieving block at the predetermined position of a retrieving frame to output to an operation control circuit. The operation control circuit discriminates whether a residual value supplied from the motion vector detecting circuit is larger than the threshold value Th and the threshold value Th which is smaller than Th or not respectively and controls the vector detecting circuit corresponding to such discrimination result. When the residual value is larger than the threshold value Th , the motion vector detecting circuit instructs execution of the motion vector detecting process utilizing the comparatively wider retrieving range. When the residual value is less then the threshold value Th and is larger than the threshold value Th , the motion vector circuit instructs execution of the motion vector detecting process utilizing the comparatively narrower retrieving range. Moreover, when the residual value E is less than the threshold value Th , the motion vector detecting circuit instructs stop of execution of the motion vector detecting process. As explained above, the motion vector detecting process can be executed corresponding to the input image data.
