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

