Important Note: By using the Optical Black (OB) transfer mode, the user can select whether to
include optical black pixels in the image stream.
7.2. Vertical binning (CM-140GE only).
The binning functions can be used to achieve higher frame rate or higher sensitivity. The
drawback is lower resolution.
Vertical binning is done by adding the charge
from pixels in adjacent lines in the horizontal
CCD register.
Fig. 13 shows the binning principle. Resolution
and frame rate for all combinations are shown
in the below table.
