description A system creates a target pixel in a target grid from a plurality of source pixels in a source grid. The system comprises a filter controller, a left portion lookup circuit, a right portion lookup circuit, a filter reconstruction unit, and a filter. The filter controller determines a first distance between the target pixel and a source pixel to the left of the target pixel, and a second distance between the target pixel and a source pixel to the right of the target pixel. The left portion lookup circuit determines filter coefficients for a left portion of the target pixel in accordance with the first difference. The right portion lookup circuit determines filter coefficients for a right portion of the target pixel in accordance with the second difference. The filter reconstruction unit creates a filter in accordance with the left and right portion filter coefficients for interpolating the target pixel from the plurality of source pixels. The filter performs the filtering operation according to the output of the filter reconstruction unit.
