Abstract
Earlier studies found that the chromaticity of ambient illuminations have different degrees of chromatic adaptation for viewing displays. This resulted in the weakness of chromatic adaptation transforms in predicting colour appearance on mobile displays. This study is aimed to collect experimental data and to propose an incomplete chromatic adaptation function based on the chromaticities of illuminants. An image including black text and white background was rendered by means of the chromatic adaptation transform (CAT02), into 42 different white stimuli displaying under ambient lightings of 5 CCTs (Correlated Color Temperature) and 2 illuminance levels. Twenty observers assessed the neutral white for each colour stimulus. Our previous study results were also combined to fit a model with different scaling factors for the incomplete adaptation factor (D) in CAT02. The optimization based on the neutral white stimulus under each ambient lighting condition suggested that the different degrees of chromatic adaptation were jointly affected by the illuminance and chromaticity of ambient illuminations.
