Organic light emitting diodes (OLEDs) are considered to be among the best flat panel display technologies owing to their wide viewing angles, high-speed response, high resolution, and simple structure. OLEDs exhibit a wide color gamut exceeding 100 % of the national television system committee (NTSC) sRGB gamut ratio. However, most movies and images are made to comply with standard specifications of the sRGB color gamut. If a sRGB image is displayed on a wide gamut display, the color tone will be distorted. In this paper, we propose a color gamut mapping system using the CIE-1931 XYZ color space for digital image processing. White point and RGB primaries correction provide color gamut correction for different measurement devices of the color gamut. An evaluation using images shows that the proposed system can convert a wide color gamut such as that of OLEDs to the color gamut of the user’s choice without color distortion.
