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 regu-
lation 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.
Autofunction AOI
The table below illustrates the advanced register for autofunction AOI.
The possible increment of this work area position and size is 128 pixels. The
