ABSTRACT:
An apparatus and method for pixel color enhancement are provided. The preferred embodiment includes a first circuitry, a second circuitry, a third circuitry, a fourth circuitry. In a preferred embodiment, the apparatus further includes a fifth circuitry. The first circuitry determines and outputs a reference value X. The second circuitry inputs the X, and (R, G, B) and subtracts X from three components (R, G, B) respectively to obtain values of (R−X), (G−X) and (B−X). The third circuitry inputs values of (R−X), (G−X) and (B−X) and scale values of (R−X), (G−X) and (B−X) by a factor S to generate values of S*(R−X), S*(G−X) and S*(B−X). The fourth circuitry16respectively adds values of S*(R−X), S*(G−X) and S*(B−X) to three components (R, G, B) to generate three enhanced components (R′, G′, B′).
