ABSTRACT:
Apparatus for processing motion vectors associated with a digital television image comprises a vector filter and a vector calculator for deriving a plurality of motion vectors respectively representing the motion of a pixel in the image, a circuit 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 for selecting a motion vector from the plurality in dependence on the testing.
