Abstract
There is provided a solid-state imaging device including a pixel array section having a plurality of unit pixels two-dimensionally arranged therein, the unit pixels including at least a photoelectric conversion section, a charge holding section, a transfer section, and a reset section, and a drive control section which controls driving of the unit pixels in a manner that a voltage as a signal level and a voltage as a reset level are each read out serially per row. The drive control section controls readout of the voltage of the charge holding section in accordance with initialization of the charge holding section performed by the reset section before the charge transfer by the transfer section.

A solid-state imaging device comprising:
- a pixel array section having a plurality of unit pixels two-dimensionally arranged therein, the unit pixels each including at least
- a photoelectric conversion section,
- a charge holding section which holds charges accumulated in the photoelectric conversion section,
- a transfer section which transfers the charges accumulated in the photoelectric conversion section to the charge holding section, and
- a reset section which resets the charges in the charge holding section;
- and
- a drive control section which controls driving of the unit pixels in a manner that a voltage as a signal level and a voltage as a reset level are each read out serially per row, the signal level corresponding to the charges accumulated in the charge holding section, the reset level corresponding to charges in the charge holding section after the reset section resets the accumulated charges,
- wherein the drive control section controls readout of the voltage of the charge holding section in accordance with initialization of the charge holding section performed by the reset section before the charge transfer by the transfer section,
- wherein the drive control section controls the driving of the unit pixels in a manner that the reset section performs the charge resetting in reading out the voltage of the charge holding section on a readout row and a non-readout row which is other than the readout row when a number of initialization rows is larger than a number of the readout rows in the pixel array section, the readout row including the charge holding section of which voltage is simultaneously read out, the initialization row including the charge holding section which is simultaneously initialized before the charge transfer by the transfer section.
