Abstract:
A method for generating a lookup table for color correction for a display device includes obtaining measured stimulus values for grayscales of primaries displayed on the display device, obtaining target stimulus values for the grayscales of the primaries, and obtaining the lookup table by comparing the measured stimulus values for the grayscales of the primaries and the target stimulus values for the grayscales of the primaries. The measured display characteristic is employed to calculate the corresponding lookup table for color correction for the display device for achieving a desired color temperature and brightness curve. It makes the adjustment of color temperature and brightness more accurate and quicker, to reduce cost.
