Chromatic adaptation is an important mechanism in the human visual system, which affects the perceived color appearance of scenes and objects under the illumination. Recent studies, however, found that the degree of chromatic adaptation was significantly affected by the chromaticities of the adapting condition, which is not characterized in the existing chromatic adaptation transforms and color appearance models. This work was carefully designed to investigate how the degree of chromatic adaptation needs to be considered to reproduce the overall color tone of scenes under the illumination having a wide range of chromaticities. Human observers viewed a scene under 85 light settings, and then adjusted the color appearance of the scene image shown on a smartphone display to match that of the physical scene. The adjustment of the image color appearance was achieved by performing chromatic adaptation transform with different image white points. The results clearly showed how the degree of chromatic adaptation varied with the illuminant chromaticities, and how the image white point should be adjusted to reproduce the color tone of an illuminated scene.

再现光照场景的色彩适应度的考虑

色适应是人类视觉系统中的一个重要机制，它影响光照下场景和物体的感知色彩外观。然而，最近的研究发现，色彩适应的程度受到适应条件色度的显着影响，这在现有的色彩适应变换和颜色外观模型中没有得到表征。这项工作经过精心设计，旨在研究如何需要考虑色度适应程度，以在具有广泛色度的照明下再现场景的整体色调。人类观察者在 85 种灯光设置下查看场景，然后调整智能手机显示屏上显示的场景图像的颜色外观以匹配物理场景的颜色。图像色彩外观的调整是通过对不同图像白点进行色适应变换来实现的。结果清楚地显示了色彩适应程度如何随光源色度变化，以及应如何调整图像白点以再现照明场景的色调。
