From: Influence of Spatial and Chromatic Noise on Luminance Discrimination
Examples of the stimuli with different Weber contrast between the target and the background. (A) Target: 4 cd/m2; Background = 40 cd/m2; Weber contrast = 90%. (B) Target: 10 cd/m2; Background = 40 cd/m2; Weber contrast = 75%. (C) Target: 15 cd/m2; Background = 40 cd/m2; Weber contrast = 62.5%. (D) Target: 20 cd/m2; Background = 40 cd/m2; Weber contrast = 50%. (E) Target: 25 cd/m2; Background = 40 cd/m2; Weber contrast = 37.5%. (F) Target: 30 cd/m2; Background = 40 cd/m2; Weber contrast = 25%.
