Patent ID: 7912310

Claim:
A method that scales a first picture to a second picture, the method comprising: pre-computing a plurality of filters to be applied to all the pixels of the first image with one or more processors; organizing the pre-computed filters in an order in which the pixels of the first image are to be processed; (a) selecting a plurality of pixels from the first image; (b) applying a particular one of the pre-computed filters to the selected plurality of pixels to produce an output pixel, wherein the particular one of the pre-computed filters is a next filter in the order of the pre-computed filters; and (c) repeating (a) and (b) for all pixels of the first image to produce a plurality of output pixels that make up the second image; and wherein at least one of the plurality of filters comprise coefficients that are a sinc function of an argument, the argument being a function of at least the distance between a first pixel in a top field of the first image and a first pixel in a bottom field of the first image.
