Claim:
1. An image capturing apparatus comprising: an image sensor including a plurality of unit pixels each having a plurality of photoelectric conversion portions for one out of a plurality of microlenses; a readout circuit that is capable of reading out pixel signals by scanning the image sensor with a first scan method of adding and reading out signals from a portion of the plurality of photoelectric conversion portions by a predetermined number of unit pixels, and a second scan method of adding and reading out signals from the plurality of photoelectric conversion portions by the predetermined number of unit pixels; a control/operation circuit configured to perform the functions of: a detection unit that obtains a defocus amount; and a controller that forms an image by determining, for each read out pixel signal, to use a pixel signal read out with the second scan method in a case in which the defocus amount is larger than a predetermined threshold value, or a larger signal out of the pixel signal read out with the second scan method and a signal obtained by using the pixel signal read out with the first scan method in a case in which the defocus amount is less than or equal to the predetermined threshold value.
