Abstract
An approach to reducing interpolation error is described. This approach generally involves using an offset correction table, populated with predetermined offset correction values, to reduce the error introduced by linear interpolation. This approach includes calculating an approximate inverse quantized value. The offset correction table is accessed, and a corrected inverse quantized value is then calculated.
