AI/AES Mode Selector
The Auto Electronic Shutter (AES) feature compensates for excessive light
levels by automatically adjusting the shutter speed of the camera. Select
AES for manual iris lenses. The default setting is AI.
Auto Iris Lens Type Selector (Video Drive or
Direct DC Drive)
Automatic iris lenses (Direct Drive (DC) or Video Drive types) are connected
to the camera via a 4-pin square socket located at the side of the camera.
Select the AI switch on the rear of the camera for all automatic iris lenses.
Then set the Auto Iris Lens Type Selector to VIDEO (Video drive) or DD
(Direct DC drive), depending on your particular lens. The default setting is
DD.
Backlight Compensation
If a strong background light such as a window exists in a scene, the camera
tries to compensate by reducing the overall exposure. This means that areas
surrounding the window become too dark. Set the backlight compensation
(BLC) to ON to eliminate the effect of an area of strong background lighting
in a scene. The default setting is BLC OFF.
BLC will only function with a manual iris lens when the Electronic Iris feature
is switched on. For Direct Drive and Video drive lenses, BLC will function
even though the Electronic Iris feature is switched off.
AGC Low / AGC High
The Automatic Gain Control feature can improve picture quality when the
level of scene illumination is low. For most applications, select AGC HIGH
(the default setting).
