The system then chooses the highest overall scoring parameter set.

choose the highest value for all of the scores
. This means that the algorithm might first
choose an
Exposure
of
2000
and a
Gain
of
25
. The second time, it might choose an
Exposure
of
1000
and a
Gain
of
50
, based on slight changes in conditions when the Autocalibrations
were performed. These two settings produce nearly identical images, however. The system
chooses the one with the highest value. An example of this is shown below.
