Abstract
This study is aiming to investigate the adaptive white point of different images on a display in terms of preference and naturalness under a dark condition and five ambient lighting conditions with different correlated color temperature (CCT). Under each ambient lighting, the natural and preferred white points were assessed by eleven observers using a categorical judgment method. The data were analyzed by the weighted average method in term of CCT and the departure from the Planckian locus (Duv) for each ambient light. The results showed a general agreement between the preferred and natural white points, the adapted white also varied according to different images. The white point of the display was also dependent on the CCT of the ambient illuminant. The Duv value for the Preferred and natural white points are both slightly below the Blackbody locus (BBL).
