Abstract
A solid-state imaging device includes a plurality of unit pixels. Each unit pixel has a photodiode, a reading transistor, a floating diffusion, a capacitance adding transistor, and a reset transistor. The reading transistor reads signal electric charges from the photodiode. The floating diffusion accumulates the signal electric charges read from the reading transistor. The capacitance adding transistor selectively adds capacitance to the floating diffusion. The reset transistor resets an electric potential of the floating diffusion.
