Description of the data path
Horizontal binning
Definition (CCD cameras only) In horizontal binning adjacent pixels of a row are combined
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 mono-
chrome CMOS sensor of Guppy PRO F-503B uses the same binning patterns 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 bin-
ning but not for averaged binning (low-noise binning). Signal-to-noise separa-
tion 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)
(only Guppy PRO F-503) on page 232.
Binning mode CCD models (monochrome) Guppy PRO F-503B/C
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.
