Description of the data path
Description
of
the
data
path
Loading an LUT into the camera
Loading
the
LUT
is
carried
out
through
the
data
exchange
buffer
called
GPDATA_BUFFER.
As
this
buffer
can
hold
a
maximum
of
2
KB,
and
a
complete
LUT
at
16384 × 14-bit
is
28 KB
,
programming
can
not
take
place
in
a
one
block
Note
•
The
input
value
is
the
14-bit
value
from
the
digitizer.
•
The
two
gamma
LUTs
use
LUT
14
and
15.
•
Gamma
1
(gamma=0.7)
switches
on
LUT
14,
gamma
2
(gamma=0.45)
switches
on
LUT
15.
After
overriding
LUT
14
and
15
with
a
user
defined
content,
gamma
functionality
is
no
longer
available
until
the
next
full
initialization
of
the
camera.
•
LUT
content
is
volatile
if
you
do
not
use
the
user
profiles
to
save
the
LUT.
