BLC (Back Light Compensation) On/Off
When BLC is turned on, the AGC, ES and IRIS operating point is determined by
averaging over the center area instead of entire field-of-view, so that a dimly-lit
foreground object at center area can be clearly distinguished from brightly-lit
backgrounds.
BLC should not be used unless it is needed to compensate for back-lit.
The default setting is Off.
FL (Flickerless Function) On/Off
When picture flicker fiercely, turn FL on, then the camera will stabilize the speed of
electronic shutter at 1/100(NTSC) or 1/120(PAL) automatically, and reduce the flicker
immediately.
The default setting is Off.
ES (Electronic Shutter) Off/On
ES ON: The camera continuously adjusts the shutter speed from 1/60 (NTSC), 1/50
(PAL) second to 1/100,000 second according to the luminance conditions of the scene.
ES OFF: The shutter speed is fixed at 1/60 (NTSC), 1/50 (PAL) second.
Set ES OFF, when auto iris lens is used or flicker is observed under a very bright
fluorescent lamp. Otherwise, turn ES on for optimum performance. The default setting
is ON.
