1. For use in a video image upconversion unit of the type that uses motion compensation to generate an interpolated field using motion vectors, a method of motion compensation comprising the steps of:

  • calculating a correlation value from the values of causal neighbor pixels of a generated field and from the values of corresponding neighbor pixels of a previous frame;

    comparing said correlation value with a threshold value; and

    setting the value of a pixel to be created within said generated field to be equal to the value of a corresponding pixel of said previous frame if said correlation value is less than said threshold value.
