Description of the data path
Description
of
the
data
path
Horizontal binning
In
horizontal
binning
adjacent
horizontal
pixels
in
a
line
are
combined
digitally
in
the
FPGA
of
the
camera
without
accumulating
the
black
level:
2 × horizontal binning:
2
pixel
signals
from
2
horizontal
neighboring
pixels
are
combined.
4 × horizontal binning:
4
pixel
signals
from
4
horizontal
neighboring
pixels
are
combined.
8 × horizontal binning:
8
pixel
signals
from
8
horizontal
neighboring
pixels
are
combined.
Light sensitivity
This
means
that
in
horizontal
binning
the
light sensitivity
of
the
camera
is
also
increased
by
a
factor
of
two
(
6 dB
),
4
(
12 dB
)
or
8
(
18 dB
).
Signal-to-noise
separation
improves
by
approx.
3,
6
or
9
dB.
Horizontal resolution
Horizontal
resolution
is
lowered,
depending
on
the
model.
Format_7 Mode_1
By
default
and
without
further
remapping
use
Format_7 Mode_1
for
2
×
horizontal
binning.
Note
Vertical resolution
is
reduced,
but
signal-to noise ratio
(SNR)
is
increased
by
about
3,
6
or
9
dB
(2
×,
4
×
or
8
×
binning).
Note
If
vertical binning
is
activated
the
image
may
appear
to
be
over-exposed
and
may
require
correction.
Note
The
image
appears
vertically
compressed
in
this
mode
and
no
longer
exhibits
a
true
aspect
ratio.
