Abstract
An imaging device includes first and second photoelectric conversion portions, a charge holding portion, first and second transfer transistors, and an amplifier portion, wherein in a first control operation, from a state in which the first and the second transfer transistors are off, the first transfer transistor is turned on while the second transfer transistor remains off, in a second control operation, the first and the second transfer transistors are being on, and a difference between a control voltage provided in the first control operation to the first transfer transistor to turn on and a control voltage provided to the first transfer transistor to turn off is smaller than difference between a control voltage provided in the second control operation to the first transfer transistor to turn on and the control voltage provided to the first transistor to turn off.
