12.6 Binning
12.6 Binning
12.6.1 Description
Binning sums the pixels in subsequent columns and rows, according to the binning
configuration. The result is then divided by the number of binned pixels. The binning feature
will result in images with lower resolution but significantly higher SNR. For instance, 2x2
binning will result in roughly twice the SNR (in bright areas of the image).
Binning is done in the digital domain of the camera.
Fig. 12.10 shows a schematic of 2x2 binning: pixels in a 2x2 neighbourhood (displayed as pixels
with the same color in the schematic) are binned together: their intensity values are summed
and divided by four. The output image has half the height and half the width of the input
image.

12.6.2 Camera settings
The camera supports binning settings of 1, 2, 4 or 8 in horizontal and vertical direction. The
relevant parameters for binning are shown in Table 12.2.
Property Type Description
BinningHorizontal Integer Number of pixels combined in binning in
horizontal direction.
BinningVertical Integer Number of pixels combined in binning in vertical
direction.
BinningBitshift Integer Additional left bitshift after binning (overflow is
ignored)
BinningSaturationMode Enumeration 0: no saturation indication; 1: output data is
saturated, if one of the pixels of the binning
region is saturated; 2: LSB of output data is set ’1’
if one of the pixels of the binning region is
saturated, else it is set to ’0’
Height Integer Height of the output image.
Width Integer Width of the output image.
Table 12.2: Binning parameters
Binning might increase the maximal frame rate if it is currently limited by the setting of the
maximal data rate (MaxDataRateInterface).
