Abstract:
1. A solid-state imaging device comprising: an imaging pixel region where a plurality of imaging pixels is disposed; a vertical selecting circuit for outputting pixel signals from imaging pixels of respective columns on a selected row of the imaging pixel region to vertical signal lines provided respectively for the columns; charge integrating amps provided respectively for the vertical signal lines of the columns so as to receive inputs of pixel signals from imaging pixels of the respective columns; a horizontal selecting circuit for transferring pixel signals output from the respective charge integrating amps by one or more horizontal signal lines; a reference-potential generating unit for generating a reference potential based on a black level of the pixel signals output through the horizontal signal lines; and charging elements for charging feedback capacitors of the charge integrating amps to the reference potential generated by the reference-potential generating unit, before pixel signals are read by the vertical selecting circuit.
