What goes into a matrix color space? The ubiquitous sRGB color space will serve as our specimen color space. Pictures are used to illustrate xyY space, chromaticity coordinates, D# white points, and the meaning of
在wikipedia上,RGB color model和RGB color space是分开的。在RGB color model里,也这样写道:The RGB color model itself does not define what is meant by red, green, and blue colorimetrically, and so the results of mixing them are not specified as absolute, but relative to the primary colors. Wh...
Source: https://en.wikipedia.org/wiki/Chromaticity#/media/File:PlanckianLocus.png The CIE chromaticity diagram (Figure 3) would ideally display the true color tones for all x,y pairs in the perceivable range of colors, which corresponds to a horseshoe-shaped part of XYZ color space, ...
Also found in: Wikipedia. Adobe RGBA color space defined by Adobe in 1998 that enables images edited in RGB to translate accurately to most color printers (CMYK printers). The Adobe RGB color model has a much greater color gamut than sRGB and Apple RGB, but not as large as CIE Lab. ...
图片来自https://en.wikipedia.org/wiki/CIE_1931_color_space 有了xy色度图,就可以通过xy的值找到对应的颜色。注意xy色度图只有色度信息,没有亮度信息,但我们前面说过,XYZ三刺激值中的Y就表示亮度。x,y,Y完整表示了一个测试光的色度和亮度,因此xy色度图也称为xyY色度图。 X和Z刺激值可以从x和y与Y计算回来...

色彩模型(Color Model)[1]:is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary col...
本文主要介绍Color Model。Color Space常常涉及到许多具体的数学操作。两者在概念上有时候也会混淆一谈,倒也无所谓,基本上只有行业内人士才需要严格区分概念。 B: 常用的Color Model简介: http://en.wikipedia.org/wiki/Color_models RGB在计算机显示中广泛采用(比如LCD,LED),其原色(Primary color)为RGB,是一种加...
详细可以参考wiki:http://en.wikipedia.org/wiki/Color_space B: 常用的Color Model简介: http://en.wikipedia.org/wiki/Color_models RGB在计算机显示中广泛采用(比如LCD,LED),其原色(Primary color)为RGB,是一种加性color model。意思是它是用哪几种光源来投射合成颜色的。几种光源(在纯黑背景上)被混合在...
The values are in what the spec calls "camera color space", "camera native color space", "camera space", "same color space as the raw image data". It's also common outside of the DNG spec to refer to color filter arrays samples as RGB: https://en.wikipedia.org/wik...
