Abstract
The MRC (Minimum resolvable contrast) is used to evaluate the performance of watched directly imaging system. The MRC mode is deduced on the basis of human visual system and signal detection. The model which involves the influence of spatial and temporal factors reflects the limited sensitivity in different object illuminance and contrast. The simulation result shows: The calculated limited sensitivity by MRC model is consistent with the reality of system. It is a more perfect model for evaluating the performance of low- light level imaging system.
