Horizontal binning
Definition
(CCD models only) In
horizontal binning
adjacent pixels of a row are combined
digitally in the FPGA of the camera without accumulating the black level. CMOS
models: horizontal binning is done in the CMOS sensor.
With the CMOS sensor of Guppy PRO F-503C, color binning is possible. The
monochrome CMOS sensor of Guppy PRO F-503B uses the same binning
patterns as the color version. Using Guppy PRO F-503B, F-503C you can choose
between averaging and additive binning.
Light sensitivity
This means that in horizontal binning the
light sensitivity
of the camera is also
increased by a factor of two (
6 dB
) or 4 (
12 dB
). This is only true for added
binning but not for averaged binning (low-noise binning). Signal-to-noise
separation improves by approx. 3 or 6 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.
Figure 43: 2 × vertical binning (Guppy PRO F-503B, F-503C)
Note
Vertical resolution
is reduced, but
signal-to noise ratio
(SNR)
is increased by about 3 or 6 dB (2 × or 4 × binning).
Note
The image appears
vertically
compressed in this mode and no
longer exhibits a true aspect ratio.
If
vertical binning
is activated the image may appear to be
overexposed and may require correction.
