Visual Sensation and Perception

Vision is an important function of human understanding of the world. Vision includes “sense” and “perception,” so it can be further divided into visual sensation and visual perception. In many cases, visual sensation is often called vision, but in fact visual perception is more important and complicated (Aumont 1994; Davis 2001; Finkel and Sajda 1994; Peterson and Gibson 1994; Zakia 1997).
