ABSTRACT:
At low light levels, the floating diffusion output stage of a CCD imager has the peaks of the reset pulses applied to its reset gate reduced. This introduces spatial integration in the direction of line scan that improves the signal-to-noise ratio of the video samples supplied as imager output.
