Binning

Binning is the process where the charge on two (or more) 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 binning by using CamExpert.

Genie supports horizontal and vertical binning independently, by a factor of 2 in each axis. Specifically if horizontal binning only is activated, a nominal 640x480 image is reduced to 320x480. If vertical binning only is activated, the image is reduced to 640x240. With both binning modes activated, the resulting image is 320x240.

Vertical binning also provides an increase in maximum acquisition frame rate. The frame rate increase depends on the camera model and amount of vertical cropping used. The following graphic illustrates binning.
