Pixel Binning for Improved Sensitivity

Pixel binning is a process that further enhances sensitivity of a CCD sensor in terms of the speed of image acquisition. This process involves taking square groups of pixels and combining them into one ‘super’ pixel, capable of holding much more light. This has the effect of reducing required exposure times. It is however important to realize that the drawback of pixel binning is a reduction in image resolution. This application note explains the different types of pixel binning available, to maximize speed of image collection whilst maintaining the quality of your images.
