In recent work [J. Opt. Soc. Am. A36, 1022 (2019)JOAOD60740-323210.1364/JOSAA.36.001022], we found that $\Delta {E^*_\textit{ab}}/{\rm s}$ΔEab∗/s in CIELAB is not suitable for describing the perceived speed of temporal color changes in full-room illumination. Two hue transitions with the same physical speed of change, in terms of $\Delta {E^*_\textit{ab}}/{\rm s}$ΔEab∗/s, were not perceived to change at the same speed. This is not really surprising, since CIELAB was not designed to characterize the perception of temporal color transitions in illumination. In this study, we further investigate the temporal uniformity of CIELAB. The stimuli were presented in a square of 4.3° visual angle surrounded by a 4000 K adapting field, similar to the viewing condition for which CIELAB was designed (i.e., where color stimuli are presented on-axis surrounded by a static adaptation field). The human observers viewed pairs of temporal color transitions which were presented sequentially, and were asked to select the one that appeared to change faster. The results confirmed that under these conditions CIELAB was also not temporally uniform. We present preliminary attempts to improve the temporal uniformity for both CIELAB and cone-excitation spaces (i.e., LMS and DKL (Derrington-Krauskopf-Lennie [J. Physiol.357, 241 (1984)JPHYA70022-375110.1113/jphysiol.1984.sp015499]).

评估CIELAB色相角的时间均匀性。

在最近的工作中[J. 选择。Soc。上午。A36,1022(2019)JOAOD60740-323210.1364 / JOSAA.36.001022],我们发现CIELAB中的$ \ Delta {E ^ * _ \ textit {ab}} / {\ rm s} $ΔEab∗ / s不适合描述在整个房间的照明中,颜色的感知速度会发生变化。在$ \ Delta {E ^ * _ \ textit {ab}} / {\ rm s} $ΔEab∗ / s的角度来看,具有相同物理变化速度的两个色相转换不会以相同的速度变化。这并不令人感到意外,因为CIELAB并非旨在表征照明中临时颜色过渡的感觉。在这项研究中,我们进一步研究了CIELAB的时间一致性。刺激以4.3°视角的正方形呈现,周围有4000 K的适应场,类似于CIELAB设计的观看条件(即,其中颜色刺激在轴向上被静态适应场包围)。人类观察者观察了顺序呈现的成对的暂时颜色过渡,并要求他们选择看起来变化更快的过渡。结果证实,在这些条件下,CIELAB在时间上也不均匀。我们目前正在进行初步尝试,以改善CIELAB和圆锥激励空间的时间均匀性(即LMS和DKL(Derrington-Krauskopf-Lennie [J. Physiol.357,241(1984)JPHYA70022-375110.1113 / jphysiol.1984.sp015499])。 )。
