WebJan 1, 2015 · 1 Perception of Brightness. Psycho-physically, brightness is the sensation delivered to consciousness corresponding to physiological activity in the eye and brain, which in turn corresponds to physical intensity of light emitted or reflected by a surface in view, measurable by photometry (see Chap. 15 ). WebJan 1, 2024 · Brightness may be strongly modulated by both edges and luminance gradients (e.g. Soranzo et al., 2009, Zavagno and Daneyko, 2008). Given these facts, it is interesting to test how pupil size affect brightness perception and eventually interact with the type of contour defining a surface (e.g. sharp luminance change vs graded luminance …
