A color CRT image display system was used to present adapting backgrounds that were spatially and temporally varied. Three observers adjusted the chromaticity of test stimuli to produce an achromatic appearance under a variety of adapting conditions. The achromatic-appearing chromaticities were used as measures of the observers' states of chromatic adaptation. The spatial configuration of the adapting background was varied to measure the spatial extent of the mechanisms responsible for chromatic adaptation. The temporal configuration of the adapting background was varied to measure the time-course of these mechanisms. The results show that chromatic adaptation is spatially localized with a time-course on the order of 10 sec. Since the mechanisms were shown to be spatially localized, the observed temporal integration across eye movements is required to allow these mechanisms to adjust to the spatially integrated scene chromaticity.
使用彩色阴极射线管图像显示系统呈现空间和时间上变化的适应背景。三名观察者调整测试刺激的色度，以在各种适应条件下产生无色外观。呈现无色外观的色度用作观察者颜色适应状态的度量。改变适应背景的空间配置以测量负责颜色适应的机制的空间范围。改变适应背景的时间配置以测量这些机制的时间进程。结果表明，颜色适应在空间上是局部化的，时间进程约为10秒。由于已证明这些机制在空间上是局部化的，因此需要观察到的跨眼球运动的时间整合，以使这些机制能够适应空间整合的场景色度。
