Abstract
In this paper, a new visual model of brightness perception is introduced to resolve apparent incompatibilities among Fechner's logarithmic relation, Stevens' power law response, and psychophysical and electrophysiological Km•I/(I+S) experimental results. The proposed visual model, which is based upon combining and extending two existing ones, is shown to predict these results successfully. Thus, a unification of three apparently conflicting visual laws emerges and the versatility and validity of the new visual model is demonstrated.
