MOTION ESTIMATION

摘要

In a method of estimating motion vectors, motion parameters (p1-p4) are determined (PC) for a given field (n-1) of a video signal; and motion vectors (D(X, n)) for a field (n) of said video signal are determined in dependence upon at least one predetermined motion vector (D(x-X, y-Y, n), D(x+X, y-Y, n), D(x, y+2Y, n-1)) and at least one additional motion vector (PV(X)) derived (PG) from said motion parameters (p1-p4).
