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.
