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

A method of driving a solid-state imaging device including a pixel, the pixel including a first photoelectric conversion unit, a first floating diffusion, a first select transistor, a first output transistor, and a first voltage control transistor, the method comprising:

• the first photoelectric conversion unit generating and accumulating signal charge by receiving light having entered the pixel and photoelectrically converting the light;
• the first floating diffusion retaining the signal charge generated by the first photoelectric conversion unit;
• the first select transistor controlling selecting of the pixel according to a first selection signal;
• the first output transistor outputting the signal charge in the first floating diffusion as a pixel signal when the pixel is selected by the first select transistor;
• and
• the first voltage control transistor controlling a voltage of an output end of the first output transistor according to a second selection signal;
• and
• a drive circuit applying the first selection signal and the second selection signal to the first select transistor and the first voltage control transistor, respectively, to turn on the first select transistor and turn off the first voltage control transistor during a reset operation and a readout operation, and to turn on the first voltage control transistor and turn off the first select transistor during the accumulating the signal charge.
