Solid-state imaging device and camera system

摘要

A solid-state imaging device includes a pixel array with unit pixels each having a photoelectric conversion device arranged in a matrix. Column signal lines are wired with respect to one column in the pixel arrangement and pixels are regularly connected to the column signal lines in accordance with rows in which pixels are positioned. A pixel signal reading unit has a column processing unit that reads pixel signals in units of plural pixels from the pixel array and performs column processing to read signals on a column basis, wherein the pixel signal reading unit includes a column input unit which can connect one or plural column signal lines arranged at a corresponding column to an input of one column processing unit through plural capacitors connected in parallel The column input unit has switches which can change a connection state between capacitors and column signal lines corresponding to the column.
