What is binning in photography?

Binning is the term used to describe the technique of combining the output of adjacent pixels on a sensor. This can be performed on pixels in a single axis or, more commonly, in both directions.

What is the purpose of pixel binning?

Pixel binning is a clocking scheme used to combine the charge collected by several adjacent CCD pixels, and is designed to reduce noise and improve the signal-to-noise ratio and frame rate of digital cameras.

Does binning increase resolution?

Summary. Binning allows cameras to artificially increase pixel size in order to gather more signal at the cost of resolution, increasing the flexibility of a camera sensor. Due to the manner in which different camera sensors work, it is important to note the differences in binning between CMOS and CCD/EMCCD.

How does binning work?

Binning is a way to group a number of more or less continuous values into a smaller number of "bins". For example, if you have data about a group of people, you might want to arrange their ages into a smaller number of age intervals.
