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 a charge store part for storing charge transferred by said transfer switch and a reset switch for resetting said charge store part;
wherein said reset switch is driven by a reset pulse and said reset pulse for one of said unit pixels is also employed to drive said transfer switch of at least one of the other of said unit pixels.

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 loating 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 φVn to the drain of the reset switch to control a reset potential thereof, pixels are selected in units of rows.
