(1) Synchronisation Selection (LL/INT)
This switch is used to select the camera synchronisation mode. When the camera is connected
to an AC supply the Line-lock (LL) mode can be used. This locks the camera frame rate to the
mains frequency so that cameras in a system are triggered at the same point on the mains AC
cycle. Also see 5, 6 and 7 Line Lock Phase Adjustment.
(2) Backlight Compensation (BLC)
The BLC (Back Light Compensation) facility compensates for back-lit scenes by enhancing
objects in the centre 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 facility 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.
