Abstract: A color conversion device includes a conversion determination module which receives input image data including a plurality of pixel data, and to determine whether a dominant color of an input image represented by the input image data is within a predetermined color conversion region, a color conversion module which performs color conversion on pixel data representing a color within the color conversion region among the plurality of pixel data when the dominant color of the input image is within the color conversion region, and a luminance conversion module which performs luminance conversion on pixel data representing a luminance within a predetermined middle luminance region among the pixel data on which the color conversion is performed.
