Abstract

Display brightness data were collected under a wide range of surround conditions. A 24 in. (60.96 cm) LCD display was used to generate color stimuli, and a 107 in. (271.78 cm) two-dimensional illuminator was used to generate various surround conditions. The brightness values of the display under 89 monitor–surround-luminance combinations were collected from 10 or 24 observers. The surround ratio, SR, i.e., the luminance ratio between the surround and the monitor, varied from 0 to 90. Based on the collected brightness data, we propose a new c value as the log function of the surround ratio, SR, to improve the performance of the CIECAM02 brightness predictor Q.
