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 ΔLmin, proposed by Narisada as an estimate of visual processability in the range of adaptation luminance -1.0 ≤ log La ≤ 3.0. The numerical values of contrast Kmin=ΔLmin/La 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 ΔLmin 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.
