Abstract
A solid-state imaging apparatus which effects an electronic shutter operation comprises a solid-state imaging device made up of a plurality of photosensitive pixels arranged in a matrix on a semiconductor substrate, a driving circuit for driving the solid-state imaging device and also controlling the photoelectric conversion time of the photosensitive pixel, a vertical CCD for clipping a first signal obtained during a longer photoelectric conversion time in the solid-state imaging device, at a specified level or above, and then adding the clipped signal to a second signal obtained during a shorter photoelectric conversion time, and a signal processing circuit for amplifying and outputting the added signal, and setting an amplification degree for the second signal to a value larger than an amplification factor for the first signal.
