Abstract
The present invention embodies high-accuracy white point adjustment with a simple circuit configuration according to an efficient algorithm in a display system for full digital processing. More particularly, the present invention is directed to a digital video interface for inputting a digital video signal outputted from a host system and a liquid-crystal display monitor for applying color conversion to the digital video signal inputted by the digital video interface without using a look-up table, in which an adjusted-value input logic for inputting adjusted values at predetermined points to achromatic colors between maximum- and minimum-gray-scale achromatic colors and a controller LSI for computing a digital video signal inputted by the digital video interface so as to converge chromaticity coordinates for achromatic colors and outputting a computed digital value in a pipeline manner are used.
