Description

The aim of the current study was to analyse the effect of ambient illumination on brightness matching on a computer display. A human size light booth, equipped with LED and fluorescent light sources, was constructed to create uniform ambient illumination for visual tests with similar chromatic characteristics. The participants adjusted the luminance of a uniform chromatic stimulus presented on a display to be equal to that of the ambient. The recorded display luminance values show large variability among the test participants and differences between the used illuminations depending on the stimulus colour. In case of white stimulus, the matched brightness values were similar while in the case of the yellow stimulus the LED ambient appeared brighter. One conclusion is that when matching a display to its ambient in terms of brightness, observers may demonstrate less variability when the ambient colour is closer to the display colour.
