Claim Text:
1. A solid-state imaging device comprising: a plurality of pixels arranged in both row and column directions, each of the pixels comprising: a plurality of first signal lines capable of being kept in a floating potential state, each of the first signal lines being connected to each of the pixels in each column; a first scanning means for selecting the pixels that output respective signals to the respective first signal lines via the voltage signal output means corresponding to each of the pixels; and a second reset means for switching between conduction and disconnection to a power source having a second reset voltage for the first signal lines by on-off control, wherein the solid-state imaging device executes a noise signal read-out operation in which each of the first signal lines is reset to the second reset voltage by turning on the second reset means and then rendered to be in a floating potential state by turning off the second reset means; each of the charge-voltage conversion terminals in the respective pixels in one row selected by the first scanning means is reset to the first reset voltage by turning on the first reset means and then rendered to be in a floating potential state by turning off the first reset means; individual voltages at the respective charge-voltage conversion terminals are read out to the respective first signal lines in the floating potential state via the voltage signal output means corresponding to each of the respective charge-voltage conversion terminals for a predetermined period of time so that the voltages are stored in the respective first signal lines; and the voltages stored in the respective first signal lines are read out so as to output noise signals from the respective pixels in the one row, and wherein the solid-state imaging device executes an optical signal read-out operation in which each of the first signal lines is reset to the second reset voltage by turning on the second reset means and then rendered to be in a floating potential state by turning off the second reset means; individual signal charges accumulated in the respective photoelectric conversion elements are transferred to the respective charge-voltage conversion terminals by the transfer means corresponding to each of the respective photoelectric conversion elements in the respective pixels in one row selected by the first scanning means; individual voltage signals voltage-converted by the respective charge-voltage conversion terminals are read out to the respective first signal lines in the floating potential state via the voltage signal output means corresponding to each of the respective charge-voltage conversion terminals for the predetermined period of time so that the voltage signals are stored in the respective first signal lines; and the voltages stored in the respective first signal lines are read out so as to output optical signals from the respective pixels in the one row.
