Modelling of human color perception depending on quick color shifts on screen

摘要

The eye is considered as the most important human sensory organ. Its important part is the retina, which converts light to neural impulses by several millions of sensor cells: rods and cones. To understand this process, modelling by computer simulation is required. The well-known phenomenon of afterimages is examined in this paper. When a fast color change on screen is performed, a color after image appears temporarily. This afterimage may result in a more intensive color perception. A model was established to characterize the color perception intensity and duration depending on color changes.
