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.
