The
Goldeye
G
contains
a
chain
of
image
processing
modules,
called
the
image
processing
chain
.
The
first
module
(called
Analog
Gain
)
receives
the
source
signal
from
the
sensor.
Each
of
the
subsequent
modules
receives
the
output
data
of
the
previous
module
as
input.
The
behavior
of
each
module
is
configurable
by
software
via
specific
GigE
features.
That
way,
it
is
possible
to
set
parameters
or
operation
modes
for
each
module.
Each
module
passes
on
the
data
to
the
succeeding
module.
The
output
of
the
last
module
is
stored
in
the
frame
memory,
which
in
turn
passes
it
on
to
the
GigE
interface
for
output.
Image
corrections
for
SWIR
sensors
The
corrections
applied
to
the
image
are
of
special
relevance
within
the
Goldeye
camera.
They
are
applied
by
the
following
modules.
•
Non
‐
uniformity
correction
(NUC)
•
Background
correction
(BC)
•
Defect
pixel
correction
(DPC)
The
corrections
need
special
correction
data
that
must
be
provided
prior
to
operating
the
image
processing
chain.
Determination
and
storage
of
correction
data
For
each
individual
camera,
specific
correction
data
is
determined
during
the
manufacturing
process.
All
necessary
correction
data
is
stored
within
the
camera‘s
non
‐
volatile
flash
memory
ex
works.
During
camera
start
‐
up,
the
available
correction
data
is
copied
from
the
flash
memory
onto
the
correction
data
memory
for
real
time
access.
From
the
correction
data
memory,
the
correction
data
is
transferred
to
the
individual
correction
modules.
The
correction
data
transfer
is
synchronized
with
the
transfer
of
image
data
from
the
sensor.
A
correction
module
may
also
write
back
to
the
correction
data
memory,
depending
on
its
functionality.
The
IR
specific
image
correction
modules
are
described
in
detail
below.

of
features
in
the

document.
It
describes
the

camera
controls
for
Allied

GigE
cameras
as
