Color correction
Why color correction?
The
spectral
response
of
a
CCD
is
different
of
those
of
an
output
device
or
the
human
eye.
This
is
the
reason
for
the
fact
that
perfect
color
reproduction
is
not
possible.
In
each
Pike
camera
there
is
a
factory
setting
for
the
color
correction
coefficients,
see
166.
Color
correction
is
needed
to
eliminate
the
overlap
in
the
color
channels.
This
overlap
is
caused
by
the
fact
that:
•
Blue
light:
is
seen
by
the
red
and
green
pixels
on
the
CCD
•
Red
light:
is
seen
by
the
blue
and
green
pixels
on
the
CCD
•
Green
light:
is
seen
by
the
red
and
blue
pixels
on
the
CCD
The
color
correction
matrix
subtracts
out
this
overlap.
Color correction in Allied Vision cameras
In
Allied
Vision
cameras
the
color
correction
is
realized
as
an
additional
step
in
the
process
from
the
sensor
data
to
color
output.
Color
correction
is
used
to
harmonize
colors
for
the
human
eye.
With
other
Allied
Vision
(color)
cameras
so
far,
you
had
the
opportunity
to
use
it
or
to
switch
it
off.
Pike
cameras
introduce
for
the
first
time
the
so-called
color
correction
matrix.
This
means:
you
are
now
able
to
manipulate
the
color-correction
coefficients
yourself.
Note
Configuration
To
configure
this
feature
in
feature
control
register,
see
281.
Note
Hue and saturation
do
not
show
any
effect
on
Pike
color
models
in
the
Raw8
and
Raw16
format,
because
color
processing
is
switched
off
in
all
Raw
formats.
