Patent ID: 8144225

Claim:
An amplification type solid-state imaging device comprising: a pixel part having a photoelectric transducer, a transfer transistor to transfer a signal charge from the photoelectric transducer to a signal charge accumulating portion, a reset transistor to reset a voltage of the signal charge accumulating portion and an amplifying transistor whose source side is connected directly to a read signal line and amplifies and reads the voltage of the signal charge accumulating portion; a control section that controls the transfer transistor and the reset transistor and controls a drain side voltage of the amplifying transistor; and a select transistor inserted between a drain side of the amplifying transistor and a high voltage power source side, the select transistor being controlled by the control section, wherein the control section resets the voltage of the signal charge accumulating portion by turning on the reset transistor for a prescribed period in a state in which the voltage of the read signal line is retained at a first voltage by making the drain side voltage of the amplifying transistor have a low voltage out of a high voltage and the low voltage before a signal charge from the photoelectric transducer is transferred to the signal charge accumulating portion and thereafter making the drain side voltage of the amplifying transistor have the high voltage to make the read signal line have a second voltage higher than the first voltage, whereby the voltage of the signal charge accumulating portion becomes higher than a voltage immediately after resetting.
