— Retinal‐illuminance distributions are the inputs of vision and of vision models, yet there has not until now been a model to compute retinal‐illuminance distributions from externally measured luminance distributions. The problematic part of the luminance‐to‐illuminance transformation is that retinal illuminance is proportional to pupil diameter, and pupil diameter has not been connected analytically to the spatiotemporal distribution of light. To remedy this deficiency, the present paper outlines a pupil‐diameter model that is currently part of an image‐quality metric. The model, a generalization of the model of Trezona with dynamics adapted from Stark, allows easy computation of retinal illuminance from measured luminance distributions in space and time.
