Abstract
A pixel in an integrated-circuit image sensor is enabled to output, throughout a sampling interval, an analog signal having an amplitude dependent, at least in part, on photocharge integrated within a photosensitive element of the pixel. A plurality of samples of the analog signal are generated during an initial portion of the sampling interval that is shorter than a settling time for a maximum possible level of the analog signal.
