Abstract
In an image sensor containing an array of pixels, a pixel signal corresponding to the state of a photosensitive element is read-out of each pixel and compared with a threshold. If the pixel signal exceeds the first threshold, the state of the photosensitive element is reset and an analog-count voltage that corresponds to the pixel is incremented.
