Abstract
A color transforming device using brightness information of an image and a display device having the same are disclosed. The color transforming device includes a color transformation memory for storing coefficient information in order to process a color transformation of an input image based on brightness of the input image; and a color transformation processing unit for correcting a color of the input image by using the coefficient information stored in the color transformation memory and outputting the color corrected input image. The present invention provides a color transforming method suitable to a display device automatically controlling output brightness according to brightness of input image by performing a color transformation according to the brightness of input image. When the present invention is implemented to the PDP, color information of input image signal is accurately reproduced by performing the color transformation according to the APC level of input image.
