Configuration of the camera

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.
