Paper Abstract

In this study, we investigated how the luminance ratio of the surround field (Ls) to that of the central field (Lc) influence the perceived blackness of the central field in a simple configuration of concentric circle (Experiment 1) and in digital images of masterpieces (Experiment 2). Results of Experiment 1 showed that perceived blackness of the central field becomes more blackish and deeper as the contrast between Lc and Ls increases. Results of Experiment 2 showed that perceived blackness of black area surrounded by relatively bright area in artistic images is stronger than the perceived blackness given by the same luminance contrast between the center and surround in a concentric circular configuration.
