Abstract
A solid-state imaging device including: a pixel section formed by a matrix-like array of a plurality of pixels performing photoelectric conversion; and a pixel signal readout section reading out a pixel signal from the pixel section in units for reading each formed by a plurality of pixels, wherein the pixel signal readout section includes a column-parallel type ADC group formed by a plurality of analog-digital converters (ADCs) for performing A-D conversion of a pixel reset level, and a signal processing system, the signal processing system obtaining only an average value of results of A-D conversion of pixel reset levels for a plurality of pixels and automatically adjusting an input offset value for the conversion range of the ADCs such that the average value of pixel reset levels will be adequately positioned with respect to the A-D conversion range.
