ABSTRACT:
A system and method of converting a red-green-blue (RGB) pixel to a red-green-blue-white (RGBW) pixel by using a W value extraction, the RGB-to-RGBW converting system including: a lookup table generator to generate an RGBW lookup table using one or more RGB lattice points; and an RGBW value computation unit to compute an RGBW value of an input pixel with respect to an RGB value of the input pixel based on the generated RGBW lookup table.
