Abstract
A maximum value Yimax and a minimum value Yimin of input pixel data Ri, Gi, Bi for each pixel are determined. A saturation adjustment value X is determined using a function g(Yimax, Yimin), white pixel data Wo is determined using a function f(Yimin), and these are used to determine output pixel data Ro, Go, Bo. Even the saturation represented by RGB three-color data is high, conversion to RGBW four-color data with improved brightness can be made, without changing the hue.
