Patent ID: 8502872

Claim:
A thermal infrared solid-state imaging device comprising: a pixel array having pixels containing at least one or more series-connected diodes disposed two-dimensionally in the horizontal direction and the vertical direction; a plurality of horizontal drive lines for connecting one end of each of the diodes commonly in each row; a plurality of vertical signal lines for connecting other end of each of the diodes commonly in each column; a vertical power supply line for supplying power to each horizontal drive line by way of a first switch, and commonly connecting the plurality of horizontal drive lines; a vertical scanning circuit for driving the switch; integrating circuits for integrating voltages at the ends of the vertical signal lines for a predetermined integration time; and current sources connected to the vertical signal lines at an opposite end to the end of the vertical signal line which is connected to the integrating circuit, wherein the integration time is equally divided substantially into two periods, and during one divided period of the integration time, energization is performed between one end of the vertical power supply line and the current source, and during the other divided period of the integration time, the energization is performed between other end of the vertical power supply line and the current source.
