Abstract:
1. An imaging device, comprising: a plurality of pixels being disposed two-dimensionally and each having a photoelectric conversion unit, a charge-voltage conversion unit converting a charge transferred from the photoelectric conversion unit into a voltage, a transfer unit transferring the charge from the photoelectric conversion unit to the charge-voltage conversion unit, an amplifying unit outputting a pixel signal according to the voltage of the charge-voltage conversion unit, and a reset unit resetting the voltage of the charge-voltage conversion unit; a vertical driving unit supplying a driving signal driving the pixels to the plurality of pixels; vertical signal lines being provided to correspond to respective columns of the plurality of pixels and to which the pixel signal is supplied; a sample hold unit sampling and holding the pixel signal supplied to each of the vertical signal lines according to a sampling control signal, and supplying to horizontal signal lines according to a horizontal driving signal; a horizontal driving unit supplying the horizontal driving signal to the sample hold unit; and a horizontal driving control unit supplying a plurality of kinds of pulse signals relating to a reading of the pixel signal from the sample hold unit to the horizontal signal lines, wherein: a circuit controlling the reset unit among the vertical driving unit is operated by an identical current source with the horizontal driving unit; the horizontal driving control unit supplies the plurality of kinds of pulse signals to the horizontal driving unit at each horizontal reading period; and the horizontal driving control unit supplies dummy pulse signals to the horizontal driving unit at least at a part of period during a period from a start time point of each horizontal blanking period to a last signal sampling time point at the horizontal blanking period from among signal sampling time points defined by the sampling control signal.
