Color Rendition Using Three-Dimensional Interpolation

A precise, multi-purpose color reproduction algorithm is introduced. This algorithm adopts 3-dimensional interpolation instead of matrix maskings or formulas. To install this calculation algorithm in devices, a simplified circuit using several LUT(ROM/RAM) and one multiplier/accumulator was developed. It can be operated up to 2 MHz pixel frequencies and its calculation error is estimated to be less than one-tenth of conventional method.
