ABSTRACT:
A method and apparatus for predicting how any given spatio-temporal light distribution would change an observer's pupil diameter. The method generates the instantaneous effect of luminance driving the pupil diameter, the cumulative driving function of the pupil diameter, and the evolving pupil diameter. Using the evolving pupil diameter together with the input luminance, the method computes the retinal illuminance distribution for the given input illuminance. The method is implemented as a software routine executed by a general purpose computer.
