A solid-state image sensor and an image capture apparatus are provided that can realize image acquisition and distance measurement while restraining the circuit scale from increasing. The solid-state image sensor includes a plurality of pixels each including a sensor unit that generates a pulse with a frequency that is based on a reception frequency of a photon, and a counter that can operate in a first mode of counting the number of pulses of a signal generated by the sensor unit, and a second mode of counting the number of pulses of a predetermined signal that is based on an elapsed time from a timing at which light is emitted from a light emitting unit.
