ABSTRACT:
A method of motion-compensated interpolation of a picture signal (Pi) having input fields, comprises the steps of providing (ME) motion vectors (D) between a first and a second input field of the picture signal (Pi), and providing (MC1, OC) an interpolated field (Po) on the basis of at least one input field in dependence upon the motion vectors (D). At least one further motion vector (Dmax) is furnished (C2) in addition to each provided motion vector (D), whereby the interpolated field (Po) is furnished (MC1, MC2, OC) in dependence upon both the first-mentioned motion vectors (D) and the further motion vectors (Dmax).
