A moving vector between frame id detected by a moving vector detecting unit and the display positions of the subfields of pixels in a block are corrected using a moving picture correcting unit in accordance with the detection values of the moving vector. The picture quality is not deteriorated when detected. In order not to output an erroneous moving vector, a lowest correction factor S1 detected by lowest correction factor detecting unit (20) is multiplied by 1.5, the correlation factors not larger than S1 are substituted by S2 (S2≤S1), and, among a plurality of blocks with the correction factors S2, the block closest to the origin is used the starting point of the moving vector. In order not to input an erroneous moving vector to the moving picture correcting unit, a moving vector is determined by the majority decision of the moving vectors of surrounding blocks. The movement of a line has first priority. <IMAGE> |
