Binning
9.1.9
On digital cameras, you can find several operations for progressing sensitivity. One of
them is the so-called "Binning". Here, the charge carriers of neighboring pixels are aggre-
gated. Thus, the progression is greatly increased by the amount of binned pixels. By using
this operation, the progression in sensitivity is coupled to a reduction in resolution.
Baumer cameras support three types of Binning - vertical, horizontal and bidirectional.
In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and
reported to the software as one single "superpixel".
In bidirectional binning, a square of neighboring pixels is aggregated.
