摘要：

In the mesopic range, cones and rods of the retina are simultaneously responsible for visual perception. They do not have the same physiological behaviour, both in their response to light and in their temporal comportment. But after the retinal processing, they share the same circuitries to the brain. The aim of this work is to develop a computational model that simulates the physiological mechanisms occurring in retinal cells in nnesopic lighting conditions. This computational retina should be able to react to images of visual scenes in the same way as the eye does in front of the real scene. It is built of spatiotennporal filters that mimic the functioning of the retinal layers. In order to validate our approach, this paper compares our results to the results of the new recommended system for nnesopic photometry based on visual performance.
