Abstract

With a matching procedure, we studied the temporal properties of direct brightness (or lightness) and chromatic changes (produced by modulation of the region being matched) and induced brightness and chromatic changes (produced by modulation of the surround of the region being matched). The amount of direct brightness and color change was found to vary only slightly with temporal frequency over the 0.5-8 Hz range studied, whereas induced changes were found to occur only at low temporal frequencies, below about 2.5 Hz. With high temporal-frequency modulation of the surround, the induced patterns appeared to flicker but not to change in brightness or color. Despite the fact that chrominance and luminance temporal contrast sensitivity functions are very different, the temporal induction curves for color and brightness were very similar. However, brightness induction was found to increase approximately linearly with increasing surround modulation up to very high levels, whereas the amount of color induction was much less dependent on the modulation depth of the surround.

摘要

通过匹配程序，我们研究了直接亮度（或明度）和色度变化（由匹配区域的调制产生）以及诱导亮度和色度变化（由匹配区域周围的调制产生）的时间特性。发现在所研究的0.5 - 8赫兹范围内，直接亮度和颜色变化的量随时间频率变化仅略有不同，而诱导变化仅在低于约2.5赫兹的低时间频率下出现。当对周围进行高时间频率调制时，诱导图案似乎会闪烁，但亮度或颜色不会改变。尽管色度和亮度时间对比敏感度函数非常不同，但颜色和亮度的时间诱导曲线非常相似。然而，发现亮度诱导随着周围调制的增加大致呈线性增加，直至非常高的水平，而颜色诱导的量在很大程度上较少依赖于周围的调制深度。
