Solid-state imaging element, method for driving the same, and camera system
First Claim
1. A solid-state imaging element, comprising:
- unit pixels each of which has a photoelectric conversion element, a transfer switch for transferring charge stored in said photoelectric conversion element and a charge store part for storing charge transferred by said transfer switch;
wherein negative voltage is applied to a gate of said transfer switch for the period during which a charge transfer pulse is not applied to the gate.

Abstract
Since the great number of elements constituting a unit pixel having an amplification function would hinder reduction of pixel size, unit pixel n,m arranged in a matrix form is comprised of a photodiode, a transfer switch for transferring charges stored in the photodiode, a floating diffusion for storing charges transferred by the transfer switch, a reset switch for resetting the floating diffusion, and an amplifying transistor for outputting a signal in accordance with the potential of the floating diffusion to a vertical signal line, and by affording vertical selection pulse φ Vn to the drain of the reset switch to control a reset potential thereof, pixels are selected in units of rows.
