Motion vector selection in television images

摘要

Apparatus for processing motion vectors associated with a digital television image comprises a vector filter (36 Fig. 2) and a vector calculator (37) for deriving a plurality of motion vectors respectively representing the motion of a pixel in the image, a circuit 101, 104 for testing the accuracy of each motion vector by differencing pixels shifted in dependence on the motion vector from two successive fields of the image to a common position in a field interpolated between the two fields, and a vector selector 103 for selecting a motion vector from the plurality in dependence on the testing.
