9.9 Set Gamma Correction
The camera supports Gamma correction function. Generally, the output of the camera’s sensor is
linear with the photons that are illuminated on the photosensitive surface of the sensor. Gamma
correction provides a non-linear mapping mechanism as shown below.
Gamma value between 0.5 and 1: image brightness increases, dark area becomes brighter.
Gamma value between 1 and 4: image brightness decreases, dark area becomes darker.
