5.1 Reduction of Image Size
5.1.4
Horizontal and vertical Decimation
A 2/2 decimation (horizontal decimation =2, vertical decimation =2) is available. It reads out
every second row and every second column. The resulting image has the same aspect ratio as
the original ROI but has a resolution that is reduced by 4 (by 2 in x- and y-direction). The
maximal frame rate is increased up to a factor of 4 (depending on the camera settings).
The
DecimationHorizontal
value is available for modification only when
DecimationVertical
=2. If
DecimationHorizontal
=2 then
DecimationVertical
can’t be modified. To modify
DecimationVertical
,
DecimationHorizontal
must first be set to 1.
5.1.5
Binning (FPGA)
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. 5.8 shows a schematic of 2x2 binning: pixels in a 2x2 neighbourhood (displayed as pixels
with the same colour 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.

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 5.2.
Binning may not be available on all camera revisions and models, see Appendix
B.
Binning might increase the maximal frame rate. The dimension of the output image
determines the maximal frame rate.
