Auto Gain - AVT Pike Technical Manual

Description of the data path

Auto gain

All Pike cameras are equipped with auto gain feature.
Note Configuration
To configure this feature in an advanced register: See
138: Advanced register: Auto gain control
When enabled auto gain adjusts the gain within the default gain limits or
within the limits set in advanced register F1000370h in order to reach the
brightness set in auto exposure register as reference.
Increasing the auto exposure value (aka target grey value) increases the
average brightness in the image and vice versa.
The applied algorithm uses a proportional plus integral controller (PI control-
ler) to achieve minimum delay with zero overshot.
The following table shows both the gain and auto exposure CSR.
