Specifying Auto Iris Gain
Although this value is factory-set, it can be adjusted as needed.
To adjust the value, use either the auto iris gain adjustment trimmer (refer to the Lens Manual) or display operations.
Regardless of the method of adjustment used, the most recent setting takes precedence.
The same auto iris gain value applies to all users, regardless of the current user. Thus, there is no need to switch users
in advance. Unlike most other setting adjustments, any changes to this setting also apply to user 0.
