Abstract:
A block-oriented pixel filter for processing an input frame into an output frame, said pixel filter having a plurality of filter taps, said input frame comprised of a plurality of input pixels, said input pixels arranged into a plurality of input pixel sets, said input pixels each comprised of a plurality of input pixel components, said output frame comprised of a plurality of output pixels, the pixel filter comprising:a coefficient generator for providing coefficients; a sorter for receiving the input frame and providing groups of input pixel components selected from more than one input pixel set; a plurality of multipliers for receiving the coefficients and the groups of input pixel components and providing products thereof, where the number of multipliers is less than the number of filter taps times the number of input pixel components in an input pixel; and an accumulator for receiving the products from the multipliers and providing output pixels.
