APPARATUS FOR CONTROLLING AUTO WHITE BALANCE AT A HIGH COLOR TEMPERATURE TO INCREASE COLOR REPRODUCTIVITY

摘要

PURPOSE: An apparatus for controlling auto white balance at a high color temperature is provided to adjust an RGB balance at a high color temperature.;CONSTITUTION: An auto white balance controller(110) compares an RGB color value detected by a color temperature sensing unit(108) with a CCM table register of a CCM(Color Correction Matrix) table. The auto white balance controller automatically adjusts the RGB color value. The auto white balance controller supplies the RGB color value to a color gain adjusting unit(106) properly for white balance. An image processor(112) receives and processes RGB data in which white balance is adjusted by the auto white balance controller from the color gain adjusting unit.;COPYRIGHT KIPO 2010
