Abstract
An image sensor includes a first semiconductor substrate provided with a pixel, including a photoelectric conversion unit that photoelectrically converts incident light to generate an electric charge, an accumulation unit that accumulates the electric charge generated by the photoelectric conversion unit, and a transfer unit that transfers the electric charge generated by the photoelectric conversion unit to the accumulation unit, and a second semiconductor substrate provided with a supply unit for the pixel, the supply unit supplying the transfer unit with a transfer signal to transfer the electric charge from the photoelectric conversion unit to the accumulation unit.
