How Binning Settings Affect Image Quality
Pixel binning refers to the process of combining data from adjacent CCD pixels to form a
single larger pixel. As a result, this provides faster acquisition speeds and, in most images,
improved light sensitivity. However, pixel binning is achieved at the cost of reduced
resolution. A binning of 2x2 means that 4 adjacent pixels are combined into one larger
pixel. A binning of 3x3 means that 9 pixels are combined into one, 4x4 means that 16 are
combined into one, and so on.
