6  Visual Adaptations and Constancy

Warning

This chapter is under active development.

Humans adapt to all sorts of sensory input, including heat, pain, smell. In all cases we care about two things: 1) the behavior after full adaptation and 2) the time course of adaptation. Before this chapter is fully developed, check out our lecture slides on adaptation.

6.1 Light Adaptation

6.2 Dark Adaptation

6.3 Chromatic Adaptation

chromatic adaptation, which is concerned with sensitivity scaling and is a direct result of light adaptation.

6.4 Color Constancy

color constancy goes beyond sensitivity scaling and involves higher-order visual functions, i.e., surface reflectance estimation.
