Binning Function
Binning is the process where the charge on two adjacent pixels is combined. This results in
increased light sensitivity since there is twice the sensor area to capture photons. The sensor
spatial resolution is reduced but the improved low-light sensitivity plus lower signal-noise ratio may
solve a difficult imaging situation. The user can evaluate the results of the binning function on the
Falcon4 by using CamExpert.
Horizontal and vertical binning functions are applied together, by factors of 2 in each axis (2x2).
Specifically with binning activated, a nominal 640x480 image is reduced to 320x240.
Vertical binning is performed in-sensor and horizontal binning digitally; therefore with binning there
is an increase in acquisition frame rate (maximum frame rate at full resolution, minimum exposure
time = 1206.2 fps (M4480) and 664.4 fps (M4400)).
The following graphic illustrates the horizontal and vertical binning mechanism.
