SOLID-STATE IMAGING DEVICE, METHOD OF DRIVING SOLID-STATE IMAGING DEVICE, AND IMAGING SYSTEM

摘要

A solid-state imaging device includes a pixel including a photoelectric conversion element, a floating diffusion layer, a transfer transistor, a reset transistor, and an amplifier transistor, and a control unit configured to supply a first voltage to a gate of the reset transistor when the charges are accumulated in the photoelectric conversion element, the first voltage being set between a second voltage and a third voltage; subsequently supply the second voltage to the gate of the reset transistor when the reset transistor is turned on in order to reset the potential of the floating diffusion layer, and subsequently supply the third voltage to the gate of the reset transistor when the amplifier transistor outputs the signal based on the potential of the floating diffusion layer.
