Binning
Binning is the combining of two or more image sensor pixels to form a new combined pixel. A binned
image using the same exposure settings as a non-binned image will show an improved signal-to-noise
ratio, reduced scanning times (due to lower spatial resolution) and save as a smaller image file size
compared with a non-binned image, at the expense of lower image resolution.
In 2 x 2 binning, 4 physical pixels on the sensor are combined into one image pixel. This operating mode
is ideal for applications that require faster acquisition and processing times and require greater signal
collection.
For this camera, the default binning value is 1 x 1,
The Binning Vertical and Binning Horizontal features in the Image Format Control set represents the
number of horizontal pixels that will be combined (added) together.
Note: Compared to running the camera in TDI stages = 2, running the camera in 2 x 2 binning mode will
result in 4x responsivity, not 2x. Any increase in output due to binning is relative to a single sensor line
(TDI stage = 1).

Description
Binning Vertical
This feature represents the number of vertical photo-
sensitive cells that must be combined (added) together: 2.
Note: TDI stages must be set to 1 before vertical binning
can be changed to 2x.
Binning Horizontal
This feature represents the number of horizontal photo-
sensitive cells that must be combined (added) together.
