发明名称 MOTION VECTOR CALCULATING SYSTEM FOR DETECTING A MOVING OBJECT ON A SCREEN
摘要 A motion vector Vx of a picture block X between a current input picture and a preceding frame picture is corrected to Vp, when said motion vector Vx differs from a motion vector Vr of adjacent blocks of said current input block, and (Svx<Thl, and Svp>/=Th2) is not satisfied, where Svx is a block difference of the block X between the current frame F0 and the preceding frame f2 for said motion vector Vx, Vp is one of motion vectors Vr giving the minimum value of Svr, and Svp is a block difference for said vp. 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.
