A motion compensator includes a video data selector, a video data editor, a vector reference data editor, a delay unit, a region data editor, and a delay unit. The video data editor outputs present frame video data and average video data. The vector reference data editor outputs previous compensation video data and present compensation video data. The region data editor outputs present frame region data, previous compensation region data, and present compensation region data. The video data selector selects one of four video data pieces based on the three pieces of region data and outputs the selected data to the video output unit.

Video processor and video processing method

To realize image conversion processing by means of filtering using a multi-tap structure without requiring that a memory to use has a high-speed capability, a merge circuit merges sampled input image signals for every plurality pieces of continuous pixel data and outputs signals, and a memory element stores approximately one frame of output data from the merge circuit The memory element outputs signals to a memory element in accordance with outputs from a memory element which stores control data which are calculated in advance. The memory element stores a larger number of input signals received from the memory element than the number of taps of a filtering circuit and outputs signals to a selection circuit The selection circuit selects signals required by the filtering circuit from input signals received from the memory element and outputs signals to the filtering circuit The filtering circuit generates output image signals, using input signals received from the selection circuit
