RGB颜色空间转换小笔记
摘自书籍: Advanced High Dynamic Range Imaging (second edition, 2018) Francesco Banterle,Alessandro Artusi,Kurt Debattista,Alan Chalmers CRC Press,Taylor & Francis Group sRGB presents a non-linear transformation for each color channel to linearize the signal when displayed on LCD and CRT display. Such a nonlinear transformation is called an electro-optical transfer function (EOTF) in the standards community. Its inverse is typically called an opto-electrical transfer function (OETF). This is because there is a non-linear relationship between the output intensity generated by the displaying device
