If both auto gain and auto shutter are enabled and if the shutter is at its upper
boundary and gain regulation is in progress, increasing the upper auto shutter
boundary has no effect on auto gain/shutter regulation as long as auto gain
regulation is active.
Auto gain control
The table below illustrates the advanced register for auto gain control.
MinValue and MaxValue limits the range the auto gain feature is allowed to use
for the regulation process. Both values are initialized with the minimum and
maximum value defined in the standard GAIN_INQ register.
Changing the auto gain range might not affect the regulation, if the regulation
is in a stable condition and no other condition affecting the image brightness is
changed.
If both auto gain and auto shutter are enabled and if the gain is at its lower
boundary and shutter regulation is in progress, decreasing the lower auto gain
boundary has no effect on auto gain/shutter regulation as long as auto shutter
regulation is active.
Both values can only be changed within the range defined by the standard
GAIN_INQ register.
Note
As with the Extended Shutter the value of MinValue and
MaxValue must not be set to a lower value than the minimum
shutter time.
