Abstract(in English) This study investigated the relationship between the perceived lightness of a surface and the spatial layout of the surrounding environment. The experiment used multiple images of indoor and outdoor scenes with different spatial layouts. Participants responded the perceived lightness of a test patch presented on the images, by adjusting that of a comparison patch presented on a uniform gray background. The scene images have an equal mean luminance, which was same as that of the gray background. Analyses showed that the responses varied according to the surrounding scene, and that they could not be explained by the contrast effect of the adjacent luminance distributions. This result suggests that perceived lightness is affected by a higher processing that estimates illumination conditions from the surrounding spatial layout.
