Patent ID: 7714920

Claim:
A solid-state imaging device comprising: a photosensitive region provided on a semiconductor substrate and having photosensitive cells which are two-dimensionally arranged in row and column directions, each photosensitive cell including a photoelectrical conversion section, a signal charge transfer section for transferring a signal charge accumulated in the photoelectrical conversion section, a signal charge accumulation section for accumulating the signal charge transferred through the signal charge transfer section, and amplification section for amplifying the signal charge accumulated in the signal charge accumulation section, and a signal charge reset section for resetting the signal charge accumulated in the signal charge accumulation section; and a power supply line for supplying a pulsed power supply voltage to the photosensitive cells, the power supply line being provided on the semiconductor substrate; and a row selection for driving the signal charge transfer section and the signal charge resetting section of each photosensitive cell, the row selection section being provided on the semiconductor substrate, wherein the power supply line is connected to the amplification section of each of the photosensitive cells, wherein said solid-state imaging device: supplies to the power supply line, as the power supply voltage, a first voltage and a second voltage, which is lower than the first voltage, so as to output signals from a selected plurality of the photosensitive cells which are aligned in one row; applies a low level voltage and a high level voltage to the signal charge reset section and the signal charge transfer section in each of the selected plurality of the photosensitive cells within a time period during which the first voltage is supplied, such that the amplification section in each of the selected plurality of the photosensitive cells are in an operational state; and applies a low level voltage and a high level voltage to the signal charge reset section in each of the selected plurality of the photosensitive cells within a time period during which the second voltage is supplied, such that the amplification section in each of the selected plurality of photosensitive cells are in a non-operational state, and wherein a potential of the second voltage is higher than zero potential.
