Horizontal Binning - AVT Pike Technical Manual

Description of the data path

Horizontal binning

In horizontal binning adjacent horizontal pixels in a line are combined dig-
itally 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 separation 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.
