Contrast Sensitivity Function (CSF)

What is Contrast Sensitivity Function (CSF)?

Contrast Sensitivity Function (CSF) meaning in Digital terms is A functional description of the visual systems threshold sensitivity to peak-to-peak luminance differences ( i.e., contrast) of a range of sine wave spatial frequencies. While the CSF is dependent on the average luminance viewing conditions, a single one is usually adopted for typical conditions.
