BLC (Back Light Compensation) ON/OFF
When BLC is turned on, the AGC, ES and IRIS operating points are 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
