Auto Back-light Compensation
This intelligent auto BLC is a newly developed digital light level control system, it is
activated automatically by screen histogram (contrast) and 225 area window
weighting integration to control iris gain and white balance simultaneous, so that the

Compensation may be insufficient when the background is extremely
bright
