Abstract

Using the method of predicting the discrimination probability of visual stimuli and the objects of actual scenes, an analysis is carried out of the threshold luminance difference ΔL<sub>min</sub>, proposed by Narisada as an estimate of visual processability in the range of adaptation luminance -1.0 ≤ log L<sub>a</sub> ≤ 3.0. The numerical values of contrast K<sub>min</sub>=ΔL<sub>min</sub>/L<sub>a</sub> substantially differ from the threshold contrasts obtained in Blackwell's experiments and those calculated by us for the same conditions of visual perception. The results of the analysis give a basis for assuming that the proposed value of ΔL<sub>min</sub> needs to be refined. It is shown that the probability of discriminating the stimulus (the object) can be used as an estimate of the visual processability.
