【摘要】 在分析彩色显示器呈色机制的基础上,讨论了如何根据使用要求调整显示器的白场和γ值、确定暗场参数的方法,推导了由数字驱动值计算显示颜色三刺激值的方法,并根据颜色叠加原理推导了一种计算显示颜色的方法。使用这种计算方法,可以在测量单色显示颜色的基础上计算复合色,从而建立显示器色彩管理的颜色查找表。这种计算方法避免了复杂的计算,还可以减少颜色测量的数量。通过实验验证了这种计算方法的正确性,计算准确性在仪器测量误差范围之内。更多还原

【Abstract】 Based on the principle of CRT the methods of adjusting CRT’s white point, black point and γvalue are discussed in this paper. The relationship between digital quantity and CIE XYZ tristimulus isalso deducted and a method of calculating CRT’s color according to the color addition is presented. Theproposed method is relative simple and fewer color measures are needed with this method. It needs onlyto measure a set of primitive colors and the additive colors are therefore can be got. The method can beeasily used to build monitors lookup table for color management system. The method is checked by theexperiment, its accuracy is relative good and the calculation errors are within the measuring error range.更多还原
