摘要： A color temperature conversion method and apparatus having a luminance correction conversion function are provided. The color temperature conversion method controls a color temperature of an image display device. In the color temperature conversion method, a user-set color temperature is compared with a pre-stored basic color temperature for each sample luminance, thus converting a color temperature of an input pixel. A luminance scale factor corresponding to the user-set color temperature is calculated with respect to the converted input pixel, and a luminance correction conversion function is performed using the calculated luminance scale factor. Accordingly, a color temperature conversion method and apparatus having a luminance correction conversion function corrects luminance using a preset luminance scale factor, thus preventing distorted gray scale representation that may occur in the conversion and correction of color temperature.
