8.1.7. Binning

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.

◄ Figure 24

binning of pixels.
◄ Figure 25
Vertical binning causes
a vertically compressed 
image
with
doubled
brightness.
◄ Figure 26
Horizontal
binning
causes  a  horizontally 
compressed image with

◄ Figure 27
Bidirectional 
binning 
causes both a hori-
zontally  and  vertically 
compressed image with
quadruple brightness.
