Vertical binning
Vertical binning increases the light sensitivity of the camera by a factor of
two by adding together the values of two adjoining vertical pixels output as
a single pixel. At the same time this normally improves signal to noise sep-
aration by about 2 dB.
Format_7 Mode_2 By default use Format_7 Mode_2 for 2 x vertical binning.
This reduces vertical resolution, depending on the model.
Figure 51: 2 x vertical binning
Note
L
Vertical resolution is reduced, but signal-to noise ratio
(SNR) is increased by about 3 dB (2 x binning).
Note
L
If vertical binning is activated the image may appear to be
over-exposed and may require correction.
Note
L
The image appears vertically compressed in this mode and
no longer exhibits a true aspect ratio.
