Abstract :
This paper simulates human visual perception with regard to visual adaptation under the change of illumination. To reflect visual adaptation in scene rendering, we adopt the mathematic models simulating photopic, scotopic, and mesopic vision. We also take consideration the characteristic that adaptation to low visibility takes longer than high visibility. As a result, the outcome of the animation has a better natural feel, especially when the brightness changes greatly.
