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 3 dB.
This reduces vertical resolution. The new resolution is approximately 1/2 of
the original resolution.
Format_7 Mode_6 By default use Format_7 Mode_6 for 2 x vertical binning.
This reduces vertical resolution, depending on the model.
Figure 39: 2 x vertical binning
Note
L
Vertical resolution is reduced, but signal-to noise ratio
(SNR) is increased by about 3 (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.
