Abstract:
1. A driving method of a solid-state imaging apparatus including a plurality of pixels, each comprising: a photoelectric conversion portion; a carrier holding portion including a semiconductor region capable of accumulating signal carriers generated in the photoelectric conversion unit, and a control electrode arranged above the semiconductor region sandwiching an insulating film between the semiconductor region and the control electrode, such that the carrier holding unit holds the signal carriers generated in the photoelectric conversion portion; an amplifying portion; and a transfer portion having a transfer electrode for controlling an electrical connection between an input portion of the amplifying portion and the carrier holding portion, wherein the driving method comprises steps of: supplying the transfer electrode with a first voltage for turning off the electrical connection through the transfer portion, the first voltage being in a polarity opposite to a polarity of a voltage supplied to the transfer electrode during the turning on period of the transfer portion; and supplying the control electrode with a second voltage during a period of holding the carrier by the carrier holding portion, the second voltage being in the same polarity as the first voltage and being larger than the first voltage.
