10.9 Binning
10.9.1 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 103
illustrates vertical binning.
On all cameras, the binning feature is available on monochrome cameras only,
except the acA1920-25 and acA2500-14, where also the color camera allows
binning.
On the acA750-30gm, only horizontal binning by 2 is available.
acA1920-25gm and acA2500-14gm
For these cameras 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.
