Patent ID: 8259204

Claim:
A solid-state imaging device comprising: a unit cell including, a photodiode configured to accumulate a signal charge obtained by photoelectric conversion of incident light, an amplifying transistor which includes a control electrode capacitively coupled to a vertical signal line, and configured to amplify the signal charge outputted from the photodiode and output the amplified signal charge to the vertical signal line, and a reset transistor configured to reset a voltage at the control electrode of the amplifying transistor; a first power supply configured to supply a drain voltage to the amplifying transistor; and a second power supply configured to supply a drain voltage to the reset transistor; and a controller configured to set the first power supply, which supplies the drain voltage to the amplifying transistor, and a voltage at the vertical signal line to a low level; set the second power supply, which supplies the drain voltage to the reset transistor to a high level; turn on the reset transistor on a first selection line so as to reset a voltage at the control electrode of the amplifying transistor; turn off the reset transistor on the first selection line; and increase the first power supply and a voltage at the vertical signal line, by setting the second power supply to a low level so as to change the voltage at the control electrode of the amplifying transistor on the first selection line.
