Adaptive Display White Point Under Various Ambient Conditions. Part 2: Dual Illumination

Year: 2026

Type: article

Abstract: ABSTRACT Adaptive displays are designed to enhance the user viewing experience by dynamically responding to ambient lighting conditions. In Part 1 of our research, we examined the influence of ambient light on chromatic adaptation and, consequently, on the optimal adjustment of the display white point. The findings, however, do not extend to a critical scenario in which users view displays near windows, either facing the window or with their back towards it, resulting in distinct foreground and background illumination. This specific situation has not been systematically investigated in previous studies. In the present study, we conducted three carefully controlled experiments to examine how the correlated color temperature (CCT) and illuminance of both the foreground and background influence chromatic adaptation. Our results indicated that background illumination exerted a more pronounced effect on chromatic adaptation compared with foreground illumination. The foreground illumination only had a minor effect when the background CCT and illuminance were low. Notably, when the foreground CCT was higher than 6500 K, the degree of chromatic adaptation was generally elevated.
