Abstract:
To provide a photoelectric conversion device with low noise at low cost. The photoelectric conversion device includes: a plurality of photoelectric conversion circuits whose output potentials change according to an amount of incident light; a plurality of reset circuits each connected to an output of each of the photoelectric conversion circuits; a plurality of amplification circuits for amplifying the output potentials of the photoelectric conversion circuits, the amplification circuits each being connected to the output of each of the photoelectric conversion circuits; a plurality of signal read circuits for reading the outputs from the amplification circuits; and a plurality of holding circuits for temporarily holding the read outputs from the amplification circuits.
