Colour Image Enhancement Based on a Gamut Extension Algorithm for Laser Displays
B-L. Na, Y-Y. Wu and W-S. Wang

The chromaticity coordinates of three primary colours are different between the laser display and the other stand television displays; the gamut range of laser is much larger than the other displays. So the images reproduced by laser display would also have higher saturation, but sometimes the high saturation images are too flaming to watch, and easy to make the viewer fell fatigue. To solve the problem, this paper proposed a new gamut mapping system, the system is applied based on the image contents. The images reproduced by the new system are more flaming and more beautiful than usual.
