  • Solid-state imaging device, driving method and electronic apparatus with electric charge transfer using an intermediate potential
    Patent number: 9571772
    Abstract: A solid-state imaging device includes a pixel and a floating diffusion. The pixel includes a photoelectric conversion element that converts incident light into and electric charge, a first transfer gate that includes a plurality of electrodes and transfers the electric charge from the photoelectric conversion element, a charge holding region that holds the electric charge transferred from the photoelectric conversion element by the first transfer gate, each of the plurality of electrodes of the first transfer gate corresponding to a sub-region of the charge holding region, and a second transfer gate that transfers the electric charge from the charge holding region. The floating diffusion region holds the electric charge transferred from the charge holding region by the second transfer gate.
