5) Exposure control
The exposure control method is selectable from the fixed exposure and the auto exposure.
This control method is valid when “ON” selecting at ALC only.
a) Fixed exposure
The exposure time is adjustable by the exposure time setting.
b) AEE
The exposure time adjusts automatically to meet the ALC target level.
Please change the ALC target level and the auto exposure control settings.

7) AEE tolerance
When the difference between the current brightness and the ALC target level becomes smaller than this
setting, the auto exposure control stops.
8) AEE threshold
When the difference between the current brightness and the ALC target level becomes greater than
“AEE thr AEE tolerance”, the auto exposure control starts.
9) AEE speed
Please set the maximum amount of the exposure time change for the auto exposure control.
When sets “0”, there is no limit.
10) Gain control
