Example 1
For image 1, increasing the bright-
ness with
ExposureTime
is sufficient
to achieve the
BrightnessAutoNomi-
nalValue
.
2
Example 2
For image 2, increasing the bright-
ness with
ExposureTime
is not enough
to reach the value of
BrightnessAu-
toNominalValue
.
Therefore, the gain is increased after
reaching
ExposureAutoMaxValue
.
BrightnessAutoPriority = GainAuto

with
Gain
is not enough to reach the
value of BrightnessAutoNominalValue.
Therefore, the ExposureTime is in-
creased after reaching
