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 x horizontal binning:
2 pixel signals from 2 horizontal neighboring pixels are
combined.
4 x horizontal binning:
4 pixel signals from 4 horizontal neighboring pixels are
combined.
8 x 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 sep-
aration 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 x horizontal binning.
