Solid state imaging device, driving method of solid state imaging device, and electronic device having a driving unit so that a potential of a drain of a charge reset unit is controlled
Abstract:
There is provided a solid state imaging device including a photoelectric conversion unit that performs photoelectric conversion of converting incident light into charges and accumulates the charges, a charge-voltage conversion unit that converts the charges which have been subjected to the photoelectric conversion by the photoelectric conversion unit into a voltage, a charge transfer unit that transfers charges to the charge-voltage conversion unit, a charge reset unit that resets charges of the charge-voltage conversion unit, and a driving unit that performs driving such that a potential of a drain of the charge reset unit is controlled so that the charges are accumulated in the photoelectric conversion unit and the charge-voltage conversion unit up to a saturation level, and then the photoelectric conversion unit is subject to light exposure.
