Abstract
Physiological receptors have different sensitive degrees to stimuli of different intensities. Eyes as an ordinary perceptive organ have different resolution thresholds to the gray scales stimuli of different intensities. This study under the ideal illuminations adopts constant-stimuli method in psychophysicals experiment methods to analyze the change rules of visual threshold perspectives when target grayscale and threshold perspective change alternatively. This study has total 20 subjects, 6 background grey levels and 11 kinds of perspectives to obtain the change rules of visual threshold perspectives for different background grey levels under the 400 lx illumination, taking the grayscale ratio under 50 % recognition rate as the grayscale ratio of the threshold perspective, taking that under 95 % recognition rate as the grayscale ratio required for basically no perspective error, and obtain the corresponding fitting formula to provide the referential basis for designs.
