Abstract: A method and system for calculating an interpolated color value for a destination pixel from color values of source pixels adjacent to the destination pixel, where calculation of the color value of the destination pixel uses one of a plurality of interpolation functions selected according to the location of the destination pixel relative to one of the adjacent source pixels. Selection of the particular interpolation may be accomplished by defining a corresponding plurality of regions within the area covered by the adjacent source pixels and assigning an interpolation function to each of the regions. The region in which the destination pixel is located is identified, and the interpolation function assigned to the identified region is applied in the destination pixel color value calculation.

Abstract: A system and method for adaptive interpolation of a color value for a destination pixel from color values of adjacent source pixels and the destination pixel's coordinate values. An adaptive color value interpolation circuit includes look-up-tables (LUTs) to store a plurality of values for each of the destination pixel's coordinates. Each of the LUTs provide to an interpolation circuit a selected one of the plurality of stored values in the LUTs according to the respective coordinate value. The interpolation circuit also receives the color values of the adjacent pixels. The interpolation circuit calculates the pixel's interpolated color value by weighting the color values of the adjacent pixels according to the selected values from the first and second LUTs.
