Description of the data path
Description
of
the
data
path
After
the
lens
has
been
focused
again
the
image
below
will
be
seen,
but
now
with
a
considerably
more
uniform
gradient.
Note
Configuration and storing non-volatile
To
configure
this
feature
in
an
advanced
register,
see
301.
To
store
shading
image
data
into
non-volatile memory
,

Note
•
The
SHDG_CTRL
register
should
not
be
queried
at
very
short
intervals.
This
is
because
each
query
delays
the
generation
of
the
shading
image.
An
optimal
interval
time
is
500
ms.
Note
•
The
calculation
of
shading
data
is
always
carried
out
at
the
current
resolution
setting.
If
the
AOI
is
later
larger
than
the
window
in
which
correction
data
was
calculated,
none
of
the
pixels
lying
outside
are
corrected.
•
For
Format_7
mode,
it
is
advisable
to
generate
the
shading
image
in
the
largest
displayable
frame
format.
This
ensures
that
any
smaller
AOIs
are
completely
covered
by
the
shading
correction.
•
The
automatic
generation
of
shading
data
can
also
be
enabled
when
image
capture
is
already
running.
The
camera
then
pauses
the
running
image
capture
for
the
time
needed
for
generation
and
resumes
after
generation
is
completed.
•
Shading
correction
can
be
combined
with
the
image
mirror
and
gamma
functionality.
•
Changing
binning
modes
involves
the
generation
of
new
shading
reference
images
due
to
a
change
in
the
image
size.
