Charles Poynton 在这方面有很好的参考资料。他的网站非常有 90 年代内味儿,但他的书(比如《Digital Video and HD》)是我读过把色彩科学以及 gamma 与 linear light coding 解释得最清楚的入门书了。https://www.poynton.ca/Poynton-color.html
Charles Poynton has good references on this. His website is very 90s, but his books (a la Digital Video and HD) are the best clearly explained introduction to color science and gamma vs linear light coding that I've ever read. https://www.poynton.ca/Poynton-color.html
……实际相机和扫描仪中的噪点”。维基百科上说:“线性部分的目的在于让曲线在零点处不至于出现无限大的斜率,从而避免引发数值计算问题。”Poynton 在他的《Digital Video and HD: Algorithms and Interfaces》一书里谈到了“杂散光”(veiling glare),接着提到 sRGB 函数几乎完美地逆转换了 CIELAB 色彩空间中的 L*(纯粹的 2.2 gamma 就做不到这一点)。他的博士论文[1]继续……
…noise in practical cameras and scanners". Wikipedia says "The purpose of the linear section is so the curve does not have an infinite slope at zero, which could cause numerical problems." Poynton's book Digital Video and HD: Algorithms and Interfaces talks about "veiling glare" and then says that the sRGB function almost perfectly inverts L* from the CIELAB color space (a pure 2.2 gamma would not do so).
