7.1.
ALC (Auto Luminance Control)
Sets the control level for the auto-iris of the lens. The FLC function sets the camera to flicker-less mode. See
also note on flicker-less mode under Fix Shutter (7.3.)
NOTE :
ALC is disabled when AES is switched on.
Settings:
OFF, ON - Luminance Level, -40 to +40; FLC (flicker-less), OFF, ON
7.2.
AES (Auto Electronic Shutter)
Adjusts the shutter speed according to light conditions. This function is typically used together with manual
iris lenses or as an alternative to AGC and DGC.
Settings:
OFF, ON, Luminance Level, -40 to +40
7.3.
Fix Shutter
Allows manual setting of the camera’s shutter speed (exposure time) to adjust the amount of light that
reaches the CCD sensor. When using this function, it is recommended to use an auto-iris lens to
automatically adjust the sensitivity of the camera to variations in light conditions.
Settings:
OFF, ON - Shutter speed PAL 1/50; NTSC 1/60, (flicker-less – PAL 1/100; NTSC 1/120), 1/180,
1/350, 1/500, 1/750, 1/1000, 1/2000, 1/4000 and 1/10 000 seconds.
NOTE 1:
When operating with artificial light sources, such as incandescent bulbs, halogen light or fluorescent tubes,
flickering in the image can occur. To eliminate flickering, set the shutter to 1/120 for PAL cameras (50Hz
mains) and 1/100 for NTSC cameras (60Hz mains).
NOTE 2:
Fix Shutter is switched OFF when the AES functions is enabled.
7.4.
Peak/Average
Makes the auto-iris lens respond more to the highlights (peak) or more to the darker (average) scenes.
Settings:
OFF, ON - Peak Mix Level, A <–> P (10 to 90%)
7.5.
Back Light compensation (BLC)
This function is used to compensate for objects in front
of a bright background, e.g. in front of a window. 48
blocks, within a matrix of 8(h) x 6(v) can be configured to
increase exposure by a predetermined amount.
Settings:
OFF, ON – individual blocks within an
area 8(h) x 6(v).
