Abstract
A solid-state imaging device according to an embodiment includes a photoelectric conversion unit, a charge transfer unit configured to transfer a charge accumulated in the photoelectric conversion unit, a first charge modulation unit to which the charge is transferred from the photoelectric conversion unit by the charge transfer unit, a second charge modulation unit, a charge accumulation unit configured to accumulate a charge overflowing from the photoelectric conversion unit during an accumulation period, a modulation switching unit configured to couple or divide the first charge modulation unit and the second charge modulation unit, and a capacitance connection unit configured to couple or divide the second charge modulation unit and the charge accumulation unit, in which, in a state of the first charge modulation unit alone and a state where the first charge modulation unit and the second charge modulation unit are coupled by the modulation switching unit, the charge accumulated in the photoelectric conversion unit is modulated into a voltage signal, and voltage signals having different conversion efficiencies are continuously read, and the charge accumulated in the photoelectric conversion unit and the charge overflowing from the photoelectric conversion unit during the accumulation period are modulated into a voltage signal and the voltage signal is read in a capacitance obtained by coupling the first charge modulation unit, the second charge modulation unit, and the charge accumulation unit.
