Abstract
An imaging system may comprise a plurality of pixels to selectively operate in a first operating mode or a second operating mode. When operating in the first operating mode, the plurality of pixels is binned during an exposure phase such that an output during a readout phase corresponds to a summed photocurrent that is a sum of a plurality of concurrent photocurrents, each corresponding to one of the plurality of pixels. When operating in the second operating mode, the plurality of pixels is not binned during the exposure phase such that an output during the readout phase corresponds to a set of separate photocurrents, each corresponding to one of a set of the plurality of pixels.
