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-080GE/CM-080GE-RA 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.
The CM-080GE/CM-080GE-RA has ON or OFF function for Vertical Binning:
