Abstract
An image capturing apparatus comprises: an image sensor having multiple segmental pixels each including multiple photoelectric conversion units arranged two-dimensionally for receiving light beams that have passed through different pupil regions, the photoelectric conversion units being divided for each segmental pixel in a first or second pupil-division direction for addition reading; a determination unit configured to determine an edge direction of an image for each divided area of the image sensor; a decision unit configured to, based on the determined edge direction, decide for each divided area either the first or second pupil-division direction; a reading control unit configured to perform addition reading of the segmental pixels by dividing the photoelectric conversion units in the first or second pupil-division direction decided, and to control the image sensor such that pairs of image signals are outputted; and a focus adjusting unit configured to carry out phase difference focus adjustments.
