Patent ID: 8830368

Claim:
A solid-state imaging device in which first and second substrates in which circuit components constituting each pixel are arranged are electrically connected to each other, wherein the pixel includes a photoelectric conversion unit that is arranged in the first substrate, an amplification circuit that amplifies a signal generated by the photoelectric conversion unit and outputs the amplified signal, a signal accumulation circuit that is arranged in the second substrate and accumulates the amplified signal output from the amplification circuit, a selection circuit that electrically connects the signal accumulation circuit to a vertical signal line and selects one of a first state in which the amplified signal accumulated in the signal accumulation circuit is output to the vertical signal line and a second state in which the signal accumulation circuit is electrically disconnected from the vertical signal line, and a differential amplification circuit that includes a first input terminal connected to a predetermined voltage and a second input terminal connected to the vertical signal line.
