ABSTRACT:
A photosensitive apparatus comprising a plurality of sets of photodiodes and a plurality of amplifiers, each amplifier being operatively connected to one set of photodiodes. A transfer circuit is associated with each photodiode for loading a charge from the photodiode to a storage node associated therewith. Readout means sequentially unload charges from each storage node in the set of transfer circuits through the amplifier, so that multiple photodiodes may operate through a single amplifier.
