Abstract:
1. A solid-state image capturing device having a photoelectric transducer portion, a charge transfer portion for transferring a signal charge from said photoelectric transducer portion and a charge detector portion for detecting said signal charge, in which said charge detector portion comprises: a floating diffusion section to which said signal charge is transferred; a reset drain section for draining said floating diffusion section of accumulated charges; and a reset gate section of buried-channel type which is provided between said floating diffusion section and said reset drain section, wherein said reset gate section has a plurality of reset electrodes that are provided adjacent to each other in the channel direction and which can be driven independently from each other, wherein at least one of said plurality of reset electrodes can be driven with a reset potential, a baffler potential, and an intermediate potential in between the reset and baffler potentials, and wherein at least two reset electrodes of said plurality of reset electrodes are driven concomitantly, and driving levels of said at least two reset electrodes are correlated with driving levels of a drive pulse from said charge transfer portion.
