Patent ID: RE42157

Claim:
A system having a photoelectric converter comprising: a plurality of photoelectric converting elements formed on a substrate, each of the photoelectric converting elements including a first electrode layer and a second electrode layer, an insulating layer formed between the first and second electrode layers for inhibiting a first type of carriers from passing through the layer, a semiconductor layer, and an injection blocking layer for inhibiting said first type of carriers from being injected into the semiconductor layer; a switch elements for applying an electric field to each layer of said photoelectric converting section in a direction so that said first type of carriers are introduced from said semiconductor layer to said second electrode layer in a refresh mode or in a direction so that said first type of carriers generated by light incident on said semiconductor layer remain in said semiconductor layer and said second type of carriers are introduced to said second electrode layer in a photoelectric conversion mode; and a signal processing means for processing signals output from the photoelectric converting elements.
