Abstract:
A color image processing apparatus performs color image display using a red display, green display, blue display and white display. The apparatus includes a white signal generation circuit generating a white signal W based on an input red signal Rin for the red display, an input green signal Gin for the green display, and an input blue signal Bin for the blue display, a yellow signal generation circuit generating a yellow signal Ye, based on the input red signal Rin, the input green signal Gin, and the generated white signal W, and a first output white signal generation circuit generating a first output white signal Wout(1) for the white display, based on the generated white signal W and the generated yellow signal Ye.
