!!! Warning
|
|
This is an **Expert Parameter**! Only change it if you understand what it does!
|
|
|
|
After changing this parameter you need to update your reference image and alignment markers!
|
|
|
|
!!! Note
|
|
A higher gain means that the sensor has a greater response to light, but also makes sensor noise more visible.
|
|
|
|
This is used when **CamAgc** is on.
|
|
|
|
!!! Note
|
|
The **Gain** is an analog multiplier applied to the raw sensor data.<br>
|
|
The **Ceiling** is the maximum gain value that the sensor will use.
