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.
