10.3.2 Gain
In industrial environments motion blur is unacceptable. Due to this fact exposure times
are limited. However, this causes low output signals from the camera and results in dark
images. To solve this issue, the signals can be amplified by user within the camera. This
gain is adjustable from 0 to 12 db.
Notice
Increasing the gain factor causes an increase of image noise and leads to missing
codes at Mono12, if the gain factor > 1.0.
