<p>PURPOSE:To detect a motion vector based on easy judgement and by a simple operation by detecting a vector with the minimum degree of matching detected by block matching, arranging peripheral vectors sequentially, performing a correlative arithmetic operation with a reference wave, and generating output in accordance with correlation. CONSTITUTION:Only vector quantity (x,y) with the minimum degree of matching is obtained after performing the block matching. Thereby, the correlation detection of the peripheral vectors is performed. For example, at a remainder comparator 31, a position of deviation with the minimum remainder per block is detected, and it is outputted as the motion vector of a plate, and is supplied to a delay circuit group 32. An orthogonal transform circuit 33 for Fourier transformation, etc., and a peak detection circuit 34 are provided, and a decision signal when a peak exists at a spatial frequency(sf)=1, 2, and 3 of axis of abscissa is taken out to the output 38 of an OR gate 35. The decision signal is supplied to a sub blocking circuit, and also, the motion vector is outputted to the output of an AND gate 36.</p> |
