Abstract

We compute the gamut of coordinates in the Commission Internationale de l'Eclairage chromaticity diagram that correspond to positive frequency-limited functions having only three degrees of freedom (a trichromatic system). The results suggest that practical colors are either suitably frequency limited to be represented by three samples or have suitably frequency-limited metamers.

摘要

我们计算了国际照明委员会色度图中与仅具有三个自由度的正频率受限函数（三色系统）相对应的色域坐标。结果表明，实际颜色要么适当地限制频率，以便由三个样本表示，要么具有适当地限制频率的同色异谱色。
