基于计算机仿真的颜色认知实验方法研究

近年来计算机仿真的实验研究方法逐渐成为颜色认知研究的主流方法，该方法克服了传统方法的诸多缺陷。本研究在现有技术的基础上构建了颜色研究仿真系统，并改进了CIE规定的有关CRT显示器颜色标定的方法。笔者通过颜色匹配实验考察了人对CRT显示器上仿真照明体颜色外观的辨别精度，结果表明上述颜色仿真系统在颜色认知实验中具有良好的适用性，并发现被试在计算机模拟颜色刺激的条件下，可进行精确的颜色匹配；不同照明条件下的色差有所不同。这些结果也为建立颜色认知模型提供了人的基准匹配数据。

A Research on the Method of Color Recongnition Experimentations with Computer Simulation Technology

The method of using computer simulation technology is gradually becoming the mainstream experimentation method in the color recognition research field in recent years, after overcoming a good many shortcomings of the traditional methods. A color simulation system was formed on the basis of the existing technology and with the improvement of the CRT monitor color calibration methods stated by CIE. Human distinction precision of color, which was the color appearance of simulated CIE illuminant displayed on the CRT monitor, was measured by a color matching experiment. The result showed that the simulation system had sound applicability in the color recognition experiment, the subjects could do high precision color matching under the condition of computer simulated color stimuli, and the color difference varied with the condition of illumination. The measured data could be used as the baseline of human color constancy models.
