Patent ID: 8687100

Claim:
A solid-state imaging device comprising: a pixel section including a plurality of pixels performing photoelectric conversion arranged in the form of a matrix; a pixel signal readout section capable of column-parallel processing including an A/D conversion section configured to read out a pixel signal from the pixel section and perform analog-digital conversion of the pixel signal, the pixels being read in groups; a voltage sampling section sampling a bias voltage generated by a voltage generating circuit for a sampling period in accordance with a control signal and supplying the sampled bias voltage to the pixel signal readout section; and a control section controlling the signal readout operation of the pixel signal readout section and the voltage sampling operation of the voltage sampling section, wherein the pixel signal readout section includes a functional portion operating when supplied with the generated bias voltage, the control section exercises control such that the sampling period during which a voltage sampling operation of the voltage sampling section is performed is other than a period in which an analog signal is read out and is other than a period in which A/D conversion is carried out, and wherein the control section is configured to exercise control to vary a timing of the sampling period at which the voltage sampling section samples the bias voltage.
