8.6 Binning
8.6.1 Binning on Monochrome Cameras
Binning increases the camera’s response to light by summing the charges from adjacent pixels into
one pixel. Two types of binning are available: vertical binning and horizontal binning.
With vertical binning, adjacent pixels from 2 rows, 3 rows, or a maximum of 4 rows in the imaging
sensor array are summed and are reported out of the camera as a single pixel. Figure 78 illustrates
vertical binning.
On all cameras, the binning feature is available on monochrome cameras only,
except the acA1920-25, where also the color camera allows binning.
For more information about color binning, see Section 8.6.2 on page 193 .
For the acA1920-25um, vertical binning works in a different way:

Vertical binning by 2 and by 4:
The gray values of adjacent pixels from 2 rows or from 4 rows are averaged.
As a consequence, the signal to noise ratio will be increased while the
camera’s response to light will not be increased.

Vertical binning by 3:
The gray values of adjacent pixels from 3 rows are combined.
As a consequence, the signal to noise ratio will be decreased while the
camera’s response to light will be slightly increased.
We recommend using vertical binning by 2 or by 4.
