Abstract

color images are usually viewed on CRT monitor screen under ambient light sources. The feeling for reproduced color on CRT monitor depends on white point of ambient light source and the CRT monitor screen. Therefore, if the effect of ambient light source is not considered, then the reproduced color does not match the intrinsic color. This paper proposes a method to investigate the effect of ambient light source on color appearance of a CRT monitor which is posited in a room illuminated by an experimental light source. The investigation for the effect of ambient light consists of two elements. One is the flare effect that the reflection on the CRT monitor screen which produced by the ambient light source. Another is the change of adaption in white point. When the images are viewed on a CRT monitor screen under ambient light, the sate of adaption is affected by both the white point of the monitor and ambient light source. Therefore, these two effects were analyzed in the experiments.
