Abstract
A solid-state imaging device comprising: a photoelectric conversion element generating photo-generated charges; an accumulation well accumulating the charges; a modulation well holding the charges from the accumulation well; a modulation transistor controlled by the charges held in the modulation well and that outputs a signal corresponding to the charges; a transfer control element changing the potential barrier of a transfer channel between the accumulation and modulation wells to control transfer of the charges; an unwanted charges discharging control element controlling the potential barrier of an unwanted charges discharging channel coupled to the accumulation well, and discharging charges that overflow from the accumulation well during a period other than the transfer period when the photo-generated charges are transferred; and a residual charges discharging control element controlling the potential barrier of a residual charges discharging channel coupled to the modulation well, and discharging residual charges in the modulation well.
