Description of the data path
Auto gain
All Pike cameras are equipped with auto gain feature.
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 aver-
age 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.
