Quizplus · Accepted Answer

Relative luminance is a measure of the lightness or darkness of a stimulus relative to its surroundings. Brightness constancy is the ability to perceive objects as maintaining their color and brightness even under different lighting conditions. Relative luminance plays a key role in achieving brightness constancy, as the visual system takes into account the luminance of the surrounding environment when perceiving the brightness of an object.
