Abstract
A pseudo-tone processing means color-reduces each RGB component of incoming display data using pseudo-tone processing. A frame memory stores the color-reduced display data before feeding it to a display through a drive means. Color reduction is performed so that the tone number of each RGB component after color reduction is G component>R component>B component. Color reduction is unequally performed in a manner which reflects contributions of each RGB component to brightness.
