Note

The user level must be set to 3 to access this function.

• Peak/Average—the Auto Iris function measures both the average light level and the

peak light level of the image and combines these two readings to control Iris. Use the

Peak/Average function to shift between more Peak mode (lower values) or more

Average mode (higher values). The default value is 64 which is slightly more Average

than Peak measurement.

• Auto Iris Setpoint—sets the target exposure level for Auto Iris. The default value is

35—higher levels give higher Iris value and thus a brighter picture.

• Momentary Iris Setpoint—sets the target exposure level for Momentary Iris (not a

relevant setting for Auto Iris)

• Auto Iris Gain—sets the speed at which the Auto Iris reacts to changing lighting

conditions. 5 = slow (default), 10 = fast.

Extended Iris

The Extended Iris function automatically adjusts the video signal level by adjusting the iris

opening, the gain level and the exposure time to suit the ambient lighting conditions.

Make sure that the SW2 button is assigned to EIris (Extended Iris) in the Operator Toolbox

> User Buttons > SW2 menu.

To switch on the Extended Iris function use the assignable button SW2 at the left-front side

of the camera. When this button is pressed once, the current value of the Extended Iris

function is displayed. Press the button twice in quick succession to toggle between on and

off.
