Abstract:
1. A solid-state imaging device, comprising: a plurality of effective pixels arranged in a plurality of rows and a plurality of columns, the effective pixel including a photoelectric conversion unit configured to generate electric charges by photoelectric conversion, and a first amplifying transistor configured to output a signal from a source of the first amplifying transistor, the signal being a signal based on the electric charges generated by the photoelectric conversion unit; a plurality of reference pixels arranged corresponding to each of the plurality of columns, the reference pixel including a second amplifying transistor configured to output a signal from a source of the second amplifying transistor, the signal being a signal based on a voltage applied thereto; a first signal line to which an effective pixel is connected, the first signal line being configured to transmit the signal output by from the source of the first amplifying transistor; a second signal line to which a reference pixel is connected, the second signal line being configured to transmit the signal output from the source of the second amplifying transistor; and a difference signal output unit provided separately from the first amplifying transistor and the second amplifying transistor, the difference signal output unit being connected to the first signal line and the second signal line and configured to perform difference processing on a difference between the signal transmitted by the first amplifying transistor and the signal transmitted by the second amplifying transistor and to output a difference signal representing a result of the difference processing.
