5.2.5 Gamma Adjustment

Gamma Adjustment assumes that the sensor's gamma is 1.0 and comes into consideration when displaying
an image on a display device. It is used to encode linear luminance to match the non-linear characteristics
of display devices. Refer to chapter 8.2.5 for more details about the theory of Gamma Correction and/or
Gamma Adjustment .
Gamma adjustment is realized by the following formula, where y' is the new pixel intensity, y the original
pixel intensity and gamma the gamma value.

y = y
Users can change the gamma value under Analog Control property like shown in Figure 36. The gamma
value can be set in range from 0.1 to 4.0 by a step of 0.1. By default the gamma value is equal to 1.0 .
