Solid-state imaging apparatus, driving method of the same and imaging system

A solid-state imaging apparatus having a plurality of pixels, wherein each of the pixels comprising:

• a photoelectric conversion element for converting an incident light into an electric charge;
• a first transfer element for transferring at a plurality of times the electric charge converted by the photoelectric conversion element an accumulating element for accumulating cumulatively the electric charge transferred at the plurality of times by the first transfer element;
• a second transfer element for transferring the electric charge accumulating cumulatively in the accumulating element;
• a floating diffusion region accumulating the electric charge transferred at the second transfer element;
• and
• an amplifying element for amplifying the electric charge in the floating diffusion region.

A driving method of a solid-state imaging apparatus having a plurality of pixels, wherein each of the pixels comprising:

• a photoelectric conversion element for converting an incident light into an electric charge;
• an accumulating element for accumulating the electric charge converted by the photoelectric conversion element;
• a first transfer element for transferring the electric charge converted by the photoelectric conversion element to the accumulating element;
• a second transfer element for transferring the electric charge accumulated in the accumulating element to a floating diffusion region;
• and
• an amplifying element for amplifying the electric charge in the floating diffusion region, wherein the method comprising steps of:
• transferring by the first transfer element, at a plurality of times, the electric charge converted by the photoelectric conversion element to the accumulating element;
• and
• accumulating by the accumulating element cumulatively the electric charge transferred at the plurality of times.
