11.2. White Balance Setting
Display of the White Balance pull-down menu:
To display natural colours, the camera needs to know the reference colour temperature of the light source.
Based on this reference colour temperature the camera will calculate the correct values for all colours. The
camera can perform a measurement by itself or the user can set up the reference colour temperature manually.
The scale unit of the colour temperature is Kelvin [K]. The following list shows the colour temperature of some
light sources for reference.
The users can select one of the White Balance Control modes according to the operating environment.
