A "contrast sensitivity function" is a diagram that illustrates the relationship between:
A) orientation and similarity
B) uniform connectedness and proximity
C) sinusoidal gratings and visual angle
D) spatial frequency and sensitivity

Question

Quizplus · Accepted Answer

The contrast sensitivity function illustrates the relationship between spatial frequency (cycles per degree of visual angle) and sensitivity to contrast. It shows the contrast threshold required for detection of a sinusoidal grating at different spatial frequencies.
