Abstract
An embodiment provides an imaging device including a pixel that includes a first photoelectric conversion portion, a second photoelectric conversion portion, a first transfer transistor, a second transfer transistor, and a floating diffusion portion. The first transfer transistor transfers a signal charge in the first photoelectric conversion portion to the floating diffusion portion. The second transfer transistor transfers a signal charge in the second photoelectric conversion portion to the floating diffusion portion. A potential at the first photoelectric conversion portion for the signal charge is higher than a potential at the second photoelectric conversion portion for the signal charge.
