BINNING
Note: the binning feature is used by the 4K model of camera only. (This feature does not apply to the 2K
models.)
Binning is the combining of two 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.
For this camera, the default horizontal binning value is 1.
The Binning Horizontal features in the Image Format Control set represents the number of horizontal
pixels that will be combined (added) together.
