Abstract
A system for generating a target pixel in a target grid from a plurality of source pixels in a source grid, said system comprising, a filter controller for determining a first distance between said target pixel and a source pixel to the left of said target pixel, and a second distance between said target pixel and a source pixel to the right of said target pixel; a left portion lookup circuit for determining filter coefficients for a left portion of said target pixel in accordance with said first difference; a right portion lookup circuit for determining filter coefficients for a right portion of said target pixel in accordance with said second difference; and a filter reconstruction unit for creating a filter in accordance with said left and right portion filter coefficients, said created filter for generating said target pixel from said plurality of source pixels.
