Description of the data path
The algorithm is based on the assumption that the R-G-B component sums of the
samples are equal, i.e., it assumes that the mean of the sampled grid pixels is to
be monochrome.
Auto shutter
In combination with auto white balance, Pike cameras are equipped with auto-
shutter feature.
When enabled, the auto shutter adjusts the shutter within the default shutter
limits or within those set in advanced register F1000360h in order to reach the
reference brightness set in auto exposure register.
Increasing the auto exposure 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.
Note
Target grey level
parameter in
SmartView
corresponds to
Auto_exposure
register 0xF0F00804 (IIDC).
Increasing the auto exposure value increases the average
brightness in the image and vice versa.
