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 and a separating portion between said photoelectric conversion element and an area to which a pixel source voltage is applied;
wherein an overflow path is formed at said separating portion.

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