1. An image sensor element comprising:
a first pixel including:
a first photoelectric conversion part which photoelectrically converts light to generate electric charge;
a first accumulation part which accumulates the electric charge generated by the first photoelectric conversion part; and
a first output part which outputs a first signal based on a voltage of the first accumulation part;
a second pixel including:
a second photoelectric conversion part which photoelectrically converts light to generate electric charge;
a second accumulation part which accumulates the electric charge generated by the second photoelectric conversion part; and
a second output part which outputs a second signal based on a voltage of the second accumulation part;
an output line to which the first output part and the second output part are connected and from which the first signal and the second signal are output;
a first wiring for causing the voltage of the first accumulation part and the voltage of the second accumulation part to be a first voltage;
a second wiring for causing the voltage of the second accumulation part to be a second voltage different from the first voltage; and
a control unit which controls the voltage of the first accumulation part via the first wiring and controls the voltage of the second accumulation part via the second wiring.
