15.7.1 色视觉色感觉的主要特征已经在第1.2节中作过介绍。这里我们仅局限于:(a)讨论辨别颜色的视觉性能;(b)简要介绍色视觉的理论;(c)介绍色视觉的缺陷。 15.7.1 色的辩别和色度的稳定性[3a] 我们希望知道,一种颜色必须变化多少,这种变化才能被一个普通的观察者发觉。由于色感觉的三维性,这种变化可能是三个参数(色相、饱和度和亮度)的任何一个或者是它们的任意组合。在这一节中,我们分别介绍在色相和饱和度方面发生变化时
15.7.1 The main features of the color visual color perception are described in Section 1.2. Here we confine ourselves only to: (a) discussing the visual properties that distinguish color; (b) briefly introducing the theory of color vision; and (c) introducing defects in color vision. 15.7.1 Color Discrimination and Chromaticity Stability [3a] We want to know how much a color must change before it can be detected by a normal observer. Due to the three-dimensional nature of the color perception, the change may be any one of three parameters (hue, saturation and brightness) or any combination thereof. In this section, we introduce separately when there is a change in hue and saturation
