Claim 18:
19. An electronic apparatus, comprising:
a signal processor;
a first photoelectric conversion element;
a first floating diffusion electrically coupled to the first photoelectric conversion element;
a first transistor, a gate of the first transistor being electrically coupled to the first floating diffusion;
a second transistor, one of a source and a drain of the second transistor being electrically coupled to one of a source and a drain of the first transistor; and
a third transistor, one of a source and a drain of the third transistor being electrically coupled to the one of the source and the drain of the first transistor and the one of the source and the drain of the second transistor, wherein the other of the source and the drain of the third transistor is electrically coupled to a node that receives a constant voltage,
wherein a gate of the third transistor is electrically connected to a node that receives a voltage control signal that controls the third transistor to be on during accumulation of signal charge by the first photoelectric conversion element and to be off during signal charge readout.
