Abstract
A motion vector V.sub.x of a picture block X between a current input picture and a preceding frame picture is corrected to V.sub.p, when said motion vector V.sub.x differs from a motion vector V.sub.r of adjacent blocks of said current input block, and (S.sub.v.sbsb.x <T.sub.hl, and S.sub.v.sbsb.p .gtoreq.T.sub.h2) is not satisfied, where S.sub.v.sbsb.x is a block difference of the block X between the current frame F.sub.0 and the preceding frame f.sub.2 for said motion vector V.sub.x, V.sub.p is one of motion vectors V.sub.r giving the minimum value of S.sub.v.sbsb.r, and S.sub.v.sbsb.p is a block difference for said v.sub.p. The present invention provides correct motion vector of a moving object on a screen irrespective of noise in a picture signal and sudden intensity change. The present invention is applicable to a frame interpolation in a television standard system conversion system, and an efficient coding of a television signal.
