As shown in Figure 20, when the gray scale value of a given input pixel is 40% (before gamma is applied), then

gray scale value is 13% after gamma is applied. Because gamma has a direct impact on the displayed gray

scale level of a pixel, it also has a direct impact on the landed duty cycle of a pixel.

The IntelliBright algorithms content adaptive illumination control (CAIC) and local area brightness boost (LABB)

also apply transform functions on the gray scale level of each pixel.

But while amount of gamma applied to every pixel (of every frame) is constant (the exponent, gamma, is

constant), CAIC and LABB are both adaptive functions that can apply a different amounts of either boost or

compression to every pixel of every frame.

Consideration must also be given to any image processing which occurs before the DLPC3479 controller.
