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.
