Description of the data path
Description
of
the
data
path
RAW
mode
is
primarily
used
to
•
save
bandwidths
on
the
IEEE1394
bus
•
achieve
higher
frame
rates
•
use
different
Bayer
demosaicing
algorithms
on
the
PC
(for
Pike
F-145
and
Pike
F-505
the
first
pixel
of
the
sensor
is
RED,
for
all
other
Pike
the
first
pixel
is
GREEN
followed
by
RED).
Sharpness
The
Pike
color
models
are
equipped
with
a
two
step
sharpness
control,
applying
a
discreet
horizontal
high
pass
in
the
Y
channel
as
shown
in
the
next
three
line
profiles.
Sharpness
0,
1
and
2
is
calculated
with
the
following
scheme:
Note
If
the
PC
does
not
perform
Bayer
to
RGB
post-processing,
the
monochrome
image
will
be
superimposed
with
a
checkerboard
pattern.
