Abstract:
A solid state image pickup device comprising:a photoelectric conversion element line having a plurality of first and second conversion elements disposed alternately, the first and second photoelectric conversion elements converting light having different colors into electric charges; first transfer means for transferring electric charges generated by the plurality of first photoelectric conversion elements to an external circuit; a first transfer gate for transferring the electric charges generated by the plurality of first photoelectric conversion elements to said first transfer means; a first drain for draining unnecessary electric charges generated by the plurality of first photoelectric conversion elements; a first drain gate for transferring the unnecessary electric charges generated by the plurality of first photoelectric conversion elements to said first drain; second transfer means for transferring electric charges generated by the plurality of second photoelectric conversion elements to an external circuit; a second transfer gate for transferring the electric charges generated by the plurality of second photoelectric conversion elements to said second transfer means; a second drain for draining unnecessary electric charges generated by the plurality of second photoelectric conversion elements; a second drain gate for transferring the unnecessary electric charges generated by the plurality of second photoelectric conversion elements to said second drain; and a controller for independently controlling a charge transfer by said first and second transfer gates or by said first and second drain gates.
