20110115959 | Solid-state imaging device, method of driving the device, and camera system - A solid-state imaging device includes: a pixel section formed by pixels performing photoelectric conversion arranged in a matrix; a pixel signal readout section capable of column-parallel processing including an A/D conversion function for reading out a pixel signal from the pixel section and performing analog-digital conversion of the signal, the pixels being read in groups; a voltage sampling section sampling a bias voltage generated by an internal or external voltage generating circuit for a 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. The pixel signal readout section includes a functional portion. The control section exercises control such that the voltage sampling operation is performed in a period other than at least either of a period in which an analog signal is read out or in which A/D conversion is carried out. | 05-19-2011 |
