Binning and Subsampling Decimation
Binning
The principal objective of the binning function is to reduce the image resolution with better final
image quality than a subsampling function. Binning reduces the output resolution by summing
several pixels together and has the advantage of reducing aliasing, increasing signal-to-noise
ratio (SNR). Subsampling – as opposed to binning – has the advantage of increasing the output
frame rate by reducing the number of rows read out, but also can introduce aliasing in the final
image. Subsampling, however, increases the output frame rate more than binning.
The following graphic illustrates the concept of 4:1 binning for a monochrome image sensor. The
values of pixels P1, P2, P3 and P4 are summed together resulting in a single larger pixel output
value.
The binning feature can be used on the full resolution image or within any area of interest.
You cannot apply both binning and subsampling decimation simultaneously.
Color cameras do not support binning.
