| dc.description.abstract | Experiments were performed on the quasi-static perception of brightness and of apparent contrast of a foveal 1-deg disk, presented either as a luminance increment or decrement against a 300 cd.m-2 background. Results suggest that the perceptual attributes of brightness and apparent (or subjective) contrast should be distinguished. For an equal brightness difference with respect to the background, luminance increments are more effective than decrements. For an equal apparent contrast it is found that increments and decrements, up to 100 cd.m-2, are about equally effective; for higher values luminance decrements are more effective. Brightness increments and decrements can both be described by a Stevens power function of the respective luminance increments and decrements. Apparent contrast can, apart from applying a usual luminance contrast formula, also be described as a power function of the luminance difference with the background. | |
