Abstract

In the low-spatial-frequency region (below 2 c/deg) contrast sensitivity to sinusoids does not depend on spatial frequency, but does depend on the number of cycles of sinusoid. Contrast sensitivity to sinusoids can vary from 14 to 60 depending on the amount of average-luminance area or flank adjacent to the sinusoid. The influence of average-luminance flanks does not depend on the width of the flank, but does depend on the equivalent number of cycles of flank.
