COLOR IMAGE PROCESSING METHOD AND DEVICE, LCD

摘要

PURPOSE: A COLOR IMAGE PROCESSING METHOD AND DEVICE, an LCD are provided to preform high-precision white point adjustment with a simple circuit formation based on efficient algorithm in a display system in full digital processing. CONSTITUTION: The device is equipped with a digital video interface(13) for inputting a digital video signal outputted from a host device, an adjustment value input means which is an LCD monitor 11 for executing color conversion without using a lookup table relative to the digital video signal inputted by the digital video interface(13), for inputting an adjustment value at a prescribed point relative to an achromatic color ranging from a maximum gradation achromatic color to a minimum gradation achromatic color, and a controller for operating in the focusing direction of chromaticity coordinates in the achromatic color relative to the digital video signal inputted by the digital video interface(13) based on the adjustment value inputted by the adjustment value input means.
