For a thorough understanding of the concept please find some properties of the possibilities (including
optional binning modes) in the diagram below.
The standard OPAL camera only offers two binning modes: no binning (1x) and 2x vertical binning.

Theoretical charge values of camera in binning modes. Table 8.1:
(*: optional only; not available on a standard camera)
NOTE: There are particular drawbacks in vertical binning. These will be discussed in par 8.2.3.
Vertical binning mode is set by means of the VBIN command.
Command syntax: VBINy
where
y=0 denotes no binning
y=1 denotes binning enabled; two vertical pixels are added
y=2 denotes binning enabled; four vertical pixels are added (OPTIONAL)
y=3 denotes binning enabled; eight vertical pixels are added (OPTIONAL)
The actual binning mode can be read back from the camera
Command syntax: VBIN?
Reply message: y
where
y = as above
Horizontal binning mode is set by means of the HBIN command.
Command syntax: HBINx (OPTIONAL)
where
x=0 denotes binning off
x=1 denotes binning on; two horizontal pixels are binned (not available on the standard camera)
The actual binning mode can be read back from the camera
Command syntax: HBIN? (OPTIONAL)
Reply message: x
where
x = as above
Binning is not available on a color camera because binning neighboring pixels would make the Bayer
color pattern useless.
