5. Control Switches
There are 6 control switches located on the sideboard, which are for the
setting of the special features. The switches in orders are for Flickerless,
Back Light Compensation, Electronic Shutter, Automatic Gain Control,
Line-Lock and Auto Iris Lens type.
FL (Flickerless Function) On/Normal
When picture flicker fiercely, turn FL on, then the camera will stabilize
the speed of electronic shutter at 1/100(EIA) or 1/120(CCIR)
automatically, and reduce the flicker immediately. The default setting is
Normal.
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.
