4.1.8 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.

Example
◄ Figure 18
Full  frame  image,  no 
binning of pixels.
◄ Figure 19
Vertical  binning  causes 
a vertically compressed 
image  with  doubled 
brightness.
◄ Figure 20
Horizontal  binning  causes  a 
horizontally  compressed  im-
age with doubled brightness.
◄ Figure 21
Bidirectional 
binning 
causes  both  a  hori-
zontally  and  vertically 
compressed image with 
quadruple brightness.
◄ Figure 22
Bidirectional 
binning 
causes  both  a  horizon-
tally and vertically com-
pressed image with six-
teenfold brightness.
