2 x horizontal binning and 4 x horizontal
binning
2 x horizontal binning:
2 pixel signals from 2 horizontal neighboring pixels
are combined and their signals are averaged.
4 x horizontal binning:
4 pixel signals from 4 horizontal 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_1
to activate
2 x horizontal binning
.
Use
Format_7 Mode_4
to activate
4 x horizontal binning
.
Figure 40: 2 x horizontal binning and 4 x horizontal binning
Note
L
Horizontal resolution
is reduced, but
signal-to noise ratio
(SNR) is increased by about 3 or 6 dB (2 x or 4 x binning).
Note
L
The image appears
horizontally
compressed in this mode
and no longer exhibits a true aspect ratio.
