The invention provides a driving method suitable for a solid-state imaging device provided with a blooming prevention structure by which the dynamic range of the solid-state imaging device can be varied suitably. Each pixel section of a solid-state imaging device includes a reset gate for controlling a resetting operation for discharging accumulated charge from a charge accumulation portion of the pixel section. By performing reset gate voltage driving so that the voltage to be applied to the reset gate may vary midway in a charge accumulation period of the pixel section, the overflow level can be raised midway in the charge accumulation period of the pixel section to expand the dynamic range. Or, the voltage to be applied to a transfer gate for controlling a transferring operation of forwarding accumulated charge from a charge accumulation portion into a floating diffusion portion or the voltage to be applied to a bias gate for controlling the potential of a floating gate is varied.
