Abstract:
1. An image capturing apparatus, comprising: an image sensor having a plurality of segmental pixels each comprising a microlens, a plurality of photoelectric conversion units arranged in two-dimensions and corresponding to the microlens; a controller configured to switching between a first readout mode and a second readout mode for obtaining a pair of image signals based on unprocessed output signals from the image sensor; and a focus adjustment unit configured to carry out focus adjustment based on a phase difference of the pair of image signals acquired from the image sensor, wherein, in the first readout mode, charges accumulated in a part of the plurality of photoelectric conversion units that is in a first section of each segmental pixel divided in a first pupil-division direction are added and readout, and in the second readout mode, charges accumulated in a part of the plurality of photoelectric conversion units that is in a second section of each segmental pixel divided in a second pupil-division direction are added and readout.
