Abstract : Equations were derived which represent a first step toward the determination of the extent to which visual performance is effected by spatial summation, temporal summation, lens aberrations, and transmittance of the optical system. Numerical evaluation of these equations and comparison with experimental visual data will give a more meaningful determination of how closely the visual performance approaches quantum limitations than can be achieved by comparison to an ideal detector. While the distinction between approaches is academic, if one is interested only in rating visual performance as compared to other sensors, the distinction is vitally important if the goal is the generation of analytic models of the visual system.
