IMAGE-PROCESSING DEVICE FOR ESTIMATING THE MOTION OF OBJECTS SITUATED IN SAID IMAGE

A TV image processing device includes a Kalman filtering estimation member (50) which provides for each image point "i" having coordinates Z.sub.i a displacement vector DK(Z.sub.i) based on information contained in two successive images I(Z.sub.i,t) and I(Z.sub.i,t-TR) separated by a period TR. It further includes a second estimation member (60) for providing for each point "i" a displacement vector DB(Z.sub.i), a quality measuring member (70) for evaluating the vectors DK(Z.sub.i) and DB(Z.sub.i) and for influencing a selector (80) for the vectors so as to select that one of the two vectors DB(Z.sub.i) and DK(Z.sub.i) which provides the best estimation quality for the output vector D(Z.sub.i). The Kalman filtering member has an input (90) for receiving the selected vector D(Z.sub.i).
