Take Green as correction standard, and manually adjust other two channels (R channel and B
channel) to let these three channels have same value.
Here we take Green as an example. For specific Balance Ratio Selector value, please refer to
the actual condition.
In order to avoid repeated correction after rebooting the camera, it is recommended to save
white balance parameter to User Set after white balance correction. You can refer to the
Section Save and Load User Set for details.
If the light source and color temperature in environment change, you need to correct white
balance again.
11.16 Set Gamma Correction
The Gamma correction function may differ by camera models.
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.
