BLC (Back Light Compensation) On/Normal
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 Normal.
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.
