<p>A video processing method and system for motion compensated filtering of interlaced television signals comprising a motion estimation device for producing motion vectors corresponding to each output sampling site, a vector processor generating a set of input coordinates for each output sampling site depending on its corresponding motion vector, a data store in memory for storing input pixel values and providing a variable delay, a plurality of multipliers and corresponding coefficient stores, and an adder to sum the partial result from each multiplier, the multipliers multiply an input pixel value, selected from the data store depending on part of the input coordinate, by a coefficient selected from the coefficient store depending on another part of the input coordinate, the filter aperture (set of filter coefficients) is selected depending on the vertical velocity component of the motion vector supplied by the motion estimation device.</p> |
