ABSTRACT:
A motion data image compression system comprises a first element to divide an I'th frame (I=1, 2, . . . N-1) between the two frames F.sub.O and F.sub.N out of N frames (where N is an integer of 2 or more) of digital motion image data, into a block B.sub.I formed of a plural number of pixels, and to determine the motion vector MVOI of frames F.sub.O and F.sub.I for each of the divided blocks B.sub.I and to determine the block B.sub.O that uses the motion vector MVOI to predict the block B.sub.I, a second element to determine the motion vector MVNI between frame F.sub.N and F.sub.I for each block B.sub.I and that uses the motion vector MVNI to determine the block B.sub.N that predicts the block B.sub.I, a third element that determines the motion vectors MVON and MVNO of frame F.sub.N and F.sub.O for each block B.sub.I, and uses the motion vectors MVON and MVNO to determine the predictive motion vector MVOI' between frame F.sub.O and F.sub.I, determine the block B.sub.O, that predicts the block B.sub.I, determine the predictive motion vector MVNI' between frames F.sub.N and F.sub.I, and that uses the predictive motion vector MVNI' to determine the block B.sub.N, that predicts block B.sub.I and the block B.sub.ON, that is the linear sum of blocks B.sub.O, and B.sub.N', a fourth element that determines the block B.sub.DC from the average value of block B.sub.I, and a fifth element that selects the block out of the blocks B.sub.O, B.sub.N, B.sub.ON, and B.sub.DC for which the correlation with block B.sub.I is greatest.
