Abstract
Official abstract text for this publication.
A solid state imaging device including multiple unit pixels including a photoelectric converter generating electrical charge in accordance with incident light quantity and accumulating the charge, a first transfer gate transferring the accumulated charge, a charge holding region holding the transferred charge, a second transfer gate transferring the held charge, and a floating diffusion region converting the transferred charge into voltage; an intermediate charge transfer unit transferring, to the charge holding region, a charge exceeding a predetermined charge amount as a first signal charge; and a pixel driving unit setting the first transfer gate to a non-conducting state, set the second transfer gate to a conducting state, transfer the first signal charge to the floating diffusion region, set the second transfer gate to a non-conducting state, set the first transfer gate to a conducting state, and transfer the accumulated charge to the charge holding region as a second signal charge.
First claim
Opening claim text (preview).
What is claimed is: 1. A solid state imaging device comprising: (1) a unit pixel including (a) a photoelectric converter configured to generate electrical charge in accordance with incident light quantity and accumulate the charge therein, (b) a first transfer gate configured to transfer the charge accumulated in the photoelectric converter, (c) a charge holding region configured to hold the charge transferred from the photoelectric converter by the first transfer gate, (d)…
