Abstract
An image sensor includes a first voltage source that supplies a first voltage and a plurality of pixels supplied with the first voltage. The pixel includes a photoelectric conversion unit that photoelectrically converts incident light, an accumulation unit to which an electric charge resulting from photoelectric conversion by the photoelectric conversion unit is transferred and accumulated, a transfer unit that transfers the electric charge from the photoelectric conversion unit to the accumulation unit; a second voltage source that supplies a second voltage, and a supply unit that supplies the transfer unit with a transfer signal based on either the first voltage supplied by the first voltage source or the second voltage supplied by the second voltage source.
