Horizontal binning
Definition
(CCD cameras only) In horizontal binning adjacent pixels of a row are com-
bined digitally in the FPGA of the camera without accumulating the black
level. CMOS cameras: 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 pat-
terns as the color version. Using Guppy PRO F-503B/C 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 x horizontal binning.
Low-noise binning
For Guppy PRO F-503, low-noise binning (averaged pixel signals) is available.
To activate this mode see Chapter
Low-noise binning mode (2 x and 4 x binning)

2 x horizontal binning
2 pixel signals from 2 horizontal
neighboring pixels are combined
and their signals are added.
2 pixel signals from 2 horizontal
adjacent same-color pixels are
combined and their signals are added
or averaged (low-noise binning).
Default: Added
4 x horizontal binning
not applicable
4 pixel signals from 4 horizontal
adjacent same-color pixels are
combined and their signals are added
or averaged (low-noise binning).
Default: Added.
Averaged? or Added?
Only added
Added or averaged.
Default: added
When the signals are averaged, the image will not be brighter than without binning.
When the signals are added, the image will be brighter than without binning.
