What is Binning Mode and how does it work?
Binning mode improves low-light performance, increases sensitivity, produces better signal-to-noise ratios and increases framerates by combining and averaging pixels.
Binning combines adjacent pixels within same color plan to increase low light performance. Combining pixels in this way reduces the effective image resolution by a factor of 4; the active pixel array of a 10MP camera in binning mode is 2.5MP.
10MP without binning at 6 fps
10MP 1080P binning mode at 30 fps
The following images compare images from a 10MP camera with and without binning.
