彩色显示与 CIE 坐标

再现系统由排成一行的三个矩阵构成,完美匹配要求传感器张成锥子空间,而 CIE 色度将强度归一化消去。

1. The reproduction pipeline as matrices

The reproduction pipeline as matrices

2. The two conditions for a perfect match

The two conditions for a perfect match

3. Gamuts and the price of non-negativity

Gamuts and the price of non-negativity

4. CIE coordinates

CIE coordinates

5. Sensors may differ from cones

A camera's three sensor classes are not shaped like human cones, yet the camera feeds a display that matches colors perfectly. Which condition makes this possible?

6. Reading the gamut triangle

A display's three primaries form a triangle on the chromaticity diagram. Why do some real colors fall outside the triangle and reproduce poorly?

7. Computing chromaticity

A light has tristimulus values X=2X = 2, Y=3Y = 3, and Z=1Z = 1. Compute the chromaticity coordinate xx and write the number rounded to two decimals.
