Solid-state imaging element, imaging device, and control method of solid-state imaging element

An imaging device comprising:

• a first transfer transistor that transfers a charge from a photoelectric conversion element to a charge holding section;
• a second transfer transistor that transfers a charge from one of the charge holding section and the photoelectric conversion element to a first floating diffusion layer;
• an overflow gate that causes the second floating diffusion layer to hold a charge having overflowed from the photoelectric conversion element;
• and
• a signal processing circuit that synthesizes a first pixel signal according to a voltage of the first floating diffusion layer and a second pixel signal according to a voltage of the second floating diffusion layer.

A control method of a solid-state imaging element, the control method comprising:

• a first transfer procedure in which a first transfer transistor transfers a charge from a photoelectric conversion element to a charge holding section;
• a second transfer procedure in which a second transfer transistor transfers a charge from one of the charge holding section and the photoelectric conversion element to a first floating diffusion layer;
• and
• a procedure in which an overflow gate causes a second floating diffusion layer to hold a charge having overflowed from the photoelectric conversion element.
