Investigating Chromatic Adaptation via Memory Colour Matching Method on a Display

Abstract

An experiment was carried out to investigate the incomplete chromatic adaptation on a self-luminous display using memory colour matching method. The goal was to distinguish between the chromatic adaptation and simultaneous colour contrast and develop models to predict each effect. Five adapting fields derived from a pilot visual matching experiment corresponding to four CCTs (2856K, 4500K, 6500K, 9000K) and fourteen familiar objects were studied. Twenty normal colour vision observers participated in the experiment. In total, 1400 matches were accumulated. Seventy corresponding pairs were obtained. The dataset was also conducted to test various CATs and to verify the D function in CAT02. The results showed that the chromatic adaptation for self-luminous display is more incomplete than that in the real scene, but the trend between CCT and degree of adaptation is consistent with our previous study.
