Binning achieves a higher frame rate, as well as better sensitivity.
On the other hand, the resolution becomes less than the full frame readout.

7.3.1 The relationship between Binning Horizontal and Width/LinePitch
If Binning Horizontal is set at 1 or 2, Width/LinePitch is changed accordingly.
Binning Horizontal = 1 Width is 3328 as the maximum
Binning Horizontal = 2 Width is 1664 as the maximum
Note: If Binning Horizontal is reset to 1 after setting to 2, the maximum value is not
changed. It is necessary to set manually.
7.3.2 The relationship between Binning Vertical and Height
If Binning Vertical is set at 1 or 2, Height is changed accordingly.
Binning Vertical = 1 Height is 2476 as the maximum
Binning Vertical = 2 Height is 1240 as the maximum
Note: If Binning Vertical is reset to 1 after setting to 2, the maximum value is not changed.
It is necessary to set manually.
7.4. Digital video output (Bit allocation)
Although the AM-800GE and AB-800GE are digital cameras, the image is generated by an
analog component, the CCD sensor. The table and diagram below show the relationship
between the analog CCD output level and the digital output.
