Video menu - Special features

Auto lighting

The Auto Lighting item of the the video menu compensates
for variations in the frequency of the power supply used for
gas discharge lamps (fluorescent or HMI lighting).
The frequency of power supply generators can vary from the
nominal value. This variation affects the lighting which in turn
affects the colour balance. If camera system and lighting are
supplied by the same power source, then the base station
auto lighting function can automatically adjust the exposure
to follow the variations and maintain a constant colour balance.
This correction only works when the camera exposure time is
set to the 50Hz or 60Hz position.
