Abstract:
1. An image capturing apparatus comprising: an image sensor including a plurality of two-dimensionally arranged pixels including pixels each having a pair of photoelectric conversion units arranged to output a pair of image signals obtained by independently receiving a pair of light beams that have passed through different exit pupil regions of an imaging optical system; a first filter formed from a summation filter; a second filter formed from the summation filter and a differential filter; an acquisition unit arranged to acquire an f-number of the imaging optical system; a filtering unit arranged to perform filtering of the pair of image signals by selecting the first filter when the f-number is less than a predetermined threshold and selecting the second filter when the f-number is not less than the threshold; and a focus detection unit arranged to perform focus detection by a phase difference method based on the pair of image signals that have undergone the filtering by the filtering unit.
