ABSTRACT:
A motion compensation technique for color video signals involves deriving at least one principal component from the video signals by means of a hotelling transform circuit and a matrix, and applying motion compensation to an interpolator (or to a compressor/decompressor) on the basis of the derived principal component. The technique avoids the need to provide three separate compensation circuits for each of the video signals while ensuring that optimum use is made of the color information in the video signals.
