Abstract:
1. An imaging apparatus comprising: a plurality of pixels including at least a first photoelectric conversion unit, a second photoelectric conversion unit, a floating diffusion portion, a first transfer transistor configured to transfer an electric carrier generated at the first photoelectric conversion unit to the floating diffusion portion, and a second transfer transistor configured to transfer an electric carrier generated at the second photoelectric conversion unit to the floating diffusion portion; a first conductive member electrically connected to a gate electrode of the first transfer transistor; a second conductive member electrically connected to a gate electrode of the second transfer transistor; and a control unit electrically connected to the first transfer transistor and the second transfer transistor via the first conductive member and the second conductive member respectively; wherein a distance of closest proximity between the first conductive member and the floating diffusion portion is shorter than a distance of closest proximity between the second conductive member and the floating diffusion portion; and wherein the control unit is configured to perform: a first control operation for turning on the first transfer transistor from a state in which both of the first transfer transistor and the second transfer transistor are off, while keeping the second transfer transistor off, and a second control operation for setting the first transfer transistor and the second transfer transistor being on in parallel with each other in a state in which an electric carrier transferred by the first control operation is held at the floating diffusion portion.
