ABSTRACT:
In a method of interpolating the motion vectors at all pixel positions in a frame on the basis of the motion vectors at plural predetermined representative points to perform motion compensated prediction of moving pictures, there is adaptively selected one of a method for dividing the frame into plural areas and interpolating the motion vector every area is selected from a conventional method of linearly interpolating a motion vector by using all the surrounding representative points, a method of separately detecting motion vectors for an area, a method of further dividing an area into plural subareas, a method of temporarily converting the values of the motion vectors at the representative points into values to be used for the motion vector interpolation, and a method of setting a fixed value as a prediction value.
