ALC (Auto Light Control)
ALC function has two control methods, which is AGC (Auto Gain Control) and auto shutter. The AGC and auto
shutter can be set individually.
The camera parameters are adjusted to brightness of image is maintained with target brightness automatically
with ALC function.
AGC or auto shutter have to set “On” to activate ALC function.
