PURPOSE: To calculate exact motion vectors even if they are fade-in and fade-out images and images having frickers. CONSTITUTION: In a block I, an accumulation is performed by inputting the picture element a (m, n) within a template in an adder 101, adding the picture element to the output of a latch 103 and reinputting the picture element in the latch 103, and the total of all the picture element values within the template is determined. Next, the average value is determined, the subtraction of this value and the picture element value delayed by a delay device 107 is performed in an adder 111, and this value is defined as a new template. In a block II, the average value of the candidate blocks Within a search window is determined, this value is subtracted from the picture element value of the candidate block, this picture element value is defined as a new candidate block and the distortion is determined with the new templete. |
