摘要：
There is less study for ordinary LCD display color gamut boundary calculation. In order to accurately and quickly acquire the gamut boundary of an ordinary LCD display screen, a novel calculation method which coupled iterative method and the inverse calculation model was proposed. The reverse characteristic calculation method is: first, the approximation input values of the known XYZ were calculated using GOG model, and then the input value RGB of known XYZ was calculated by successive approximation method, a positive characteristic model and the function between the main stimulus and primary input value were adopted during the process of successive approximation calculation. The calculation steps are: the initial value of iterative calculation is appointed firstly, then XYZ of color point which belongs to any elevation angle on any hue surface is calculated by iterative computation. Then the device value RGB of the XYZ is calculated. Lastly, whether the color point located on the color gamut boundary is based on the values of RGB. Experimental results show that the new algorithm requires fewer samples and less computation time, and its calculation results can better meet the actual requirements than SMGBD. The results indicate that this method can well calculate color gamut boundary of ordinary LCD screen. © 2019, Science Press. All right reserved.
