Solid-state imaging device having photoelectric converting portions and first and second transfer portions

Abstract

A solid-state imaging deviceis provided with a plurality of photoelectric converting portionsand first and second shift registers. Each photoelectric converting portionhas a photosensitive regionwhich generates a charge according to incidence of light and which has a planar shape of a nearly rectangular shape composed of two long sides and two short sides, and a potential gradient forming regionwhich forms a potential gradient increasing along a predetermined direction parallel to the long sides forming the planar shape of the photosensitive region, in the photosensitive region,. The plurality of photoelectric converting portionsare juxtaposed along a direction intersecting with the predetermined direction. The first and second shift registersacquire charges transferred from the respective photoelectric converting portionsand transfer them in the direction intersecting with the predetermined direction to output them. This achieves the solid-state imaging device capable of quickly reading out the charge generated in the photosensitive region, without complicating image processing.
