计算机模拟色仿真研究

根据色度学的原理，探讨在常规的ＴＶＧＡ彩色显示器上模拟具有要求的ＣＩＥ色品坐标和亮度值的颜色的技术。在对彩显进行白平衡调整和荧光粉色度特性定标的基础上，考虑了三原色荧光粉之间的相关性，提出了一种分段线性回归并逐次叠加逼近的算法。利用与测色系统的通信接口获得实测样品色的光谱反射比数据，经数据分析和处理，直接对显示器颜色缓冲器进行底层编程和迭代修正，在ＣＲＴ上得到了逼真的颜色。

Research on Computer Color Simulation

Based on the theory of colorimetry , the technology for simulating colors having desired CIE chromaticity coordinates and luminances on general TVGA CRT monitors is discussed. On white-balance adjustment and calibration of the color monitor, the relation between the RGB phosphors is studied, thus a model with piecewise linear programming and progressively addition approaching algorithm is setup. Having obtained the spectral reflectance of the sample color to be simulated by an interfance with a color measurement system9 the frame buffer of the monitor is directly programmed and the digital input values to it is corrected by iteration such that a vivid color is displayed on the CRT color monitor.
