Abstract

The motion compensated temporal interpolator is capable of determining when a background scene is covered or uncovered by a foreground object by projecting motion vectors determined for the output field onto temporally adjacent input fields (i/p1, i/p2) and detecting the number of times each input pixel is used as a source for the output pixel - covering corresponds to multiple pixel use in the following field while uncovering corresponds to multiple pixel use in the preceding field. The motion vectors for output pixels in a covered area can then be corrected by forward projecting vectors from the preceding frame pair whereas output pixels in an uncovered area are corrected by backward projecting vectors from the following pair. <IMAGE>
