luminance contrast การใช้

In addition, human vision is sensitive to luminance contrast ratio.
Here, luminance contrast is used as an example, but the formulas can also be applied to other physical quantities.
The duration of suppression in both methods is maximized if the image being suppressed has low luminance contrast or a low spatial frequency spectrum.
The patterns are usually high in luminance contrast ( bright flashes of light alternating with darkness, or white bars against a black background ).
The " luminance contrast " is the ratio between the higher luminance, L H, and the lower luminance, L L, that define the feature to be detected.
