Abstract:
1. An image sensor comprising a plurality of pixels, each pixel having: a plurality of photoelectric conversion units configured to receive a plurality of light fluxes that pass through different exit pupil regions of an optical system that is disposed on an object side of said image sensor and accumulate charges, respectively; a separation portion configured to separate said plurality of photoelectric conversion units; and a setting unit configured to selectively set an electric potential of said separation portion to any one of a plurality of electric potentials, wherein: signals in accordance with accumulated charges can be separately read out from said plurality of photoelectric conversion units; and when an electric potential of a separation portion that separates said plurality of pixels is taken as a reference potential, the plurality of electric potentials include a first electric potential that is higher than the reference potential, a second electric potential that is lower than the reference potential, and a third electric potential that is higher than the reference potential and lower than the first electric potential.
