EverFocus EHD525EX BLC Back Light Compensation ON/OFF, FL Flickerless Function ON/OFF

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.
