为了检验各颜色匹配函数(CMFs)计算不同年龄观察者锥细胞响应的表现, 利用比较法实验得到56名观察者对5个色中心的20对近同色异谱色样对目视评价色差数据, 与不同颜色匹配函数比较, 分别计算标准化残差平方和因子与相关系数。结果表明, 各颜色匹配函数测试不同年龄段观察者的结果差异较大。对年轻观察者, S2, S6表现较好, CIE1931的计算结果较差；而对老年观察者, CIE1931表现较好, CIE1964的计算结果较差。选用CIE1964颜色匹配函数优化D65光源照明下不同年龄段观察者锥细胞响应, 优化后的CIE1964计算性能有所提高；同样, 检验LED光源照明下的实验结果, 测试性能也有所提高。

To test performances of different color matching functions (CMFs), we make 20 pairs of nearly metameric color patches based on 5 target colors (gray, brown, b-green, blue, and purple). The visual data from 56 observers is adopted to calculate the standardized residual sum of square and correlation coefficient. The behaviors of different CMFs from the young and old observers have large discrepancies. For young observers, S2 and S6 outperform others and CIE1931 has the worst performance. While, for old observers, CIE1931 outperforms others and CIE1964 has the worst performance. Visual data from observers under the D65 light source is used to optimize CIE1964 CMFs. After optimizing, performances for different age group improves not only for D65 light source, but also for light emitting diode source.
