2 x vertical binning and 4 x vertical binning
2 x vertical binning:
2 pixel signals from 2 vertical neighboring pixels are
combined and their signals are averaged.
4 x vertical binning:
4 pixel signals from 4 vertical neighboring pixels are
combined and their signals are averaged.
Because the signal is averaged, the image will not be brighter as without bin-
ning.
Use
Format_7 Mode_2
to activate
2 x vertical binning
.
Use
Format_7 Mode_5
to activate
4 x vertical binning
.
Figure 39: 2 x vertical binning and 4 x vertical binning
Note
L
Vertical resolution
is reduced, but
signal-to noise ratio
(SNR) is increased by about 3 to 6 dB (2 x or 4 x binning).
Note
L
The image appears
vertically
compressed in this mode and
no longer exhibits a true aspect ratio.
