(1) Synchronization Selection (LL/INT)
This switch is used to select the camera synchronization mode. When the camera is connected to
an AC power supply, the Line-lock (LL) mode can be used. This locks the camera frame rate to the
power supply frequency so that cameras in a system are triggered at the same point on the power
supply AC cycle. Also see 5, Line Lock Phase Adjustment Potentiometer.
(2) Backlight Compensation (BLC)
The BLC (Back Light Compensation) feature compensates for back-lit scenes by enhancing objects
in the center of the scene which would previously have been in silhouette. Select ON or OFF using
the BLC switch. Default is OFF. BLC will only function with a manual iris lens when the Electronic Iris
facility is switched on. For direct drive and auto-iris lenses, BLC will still function even though the
Electronic Iris is switched off.
(3) Gamma
Two different gamma correction options are available. Select Normal (0.45) to provide increased
visibility in dark areas of the scene, or Linear (1.0). The default setting is Normal.
