1. An image capturing apparatus comprising:
an image sensor configured to be able to output an image capturing signal, in which a subject image is captured, and a focus detection image signal, for which light that has passed through regions with different exit pupils of an imaging optical system has been photoelectrically converted; and
at least one processor or circuit configured to function as:
a focus detection unit configured to set, in the output signal of the image sensor, a focus detection range for performing focus detection, and to perform focus detection, in each of a plurality of focus detection frames in the focus detection range, based on the focus detection image signal; and
a focus adjustment unit configured to perform a focus adjustment, during a shooting preparation operation and a shooting operation, based on an output of the focus detection unit, for tracking a subject,
wherein the focus detection unit makes the focus detection range for tracking the subject and performing the focus adjustment for the subject during the shooting operation broader than a range of a focus detection display frame indicating a focus detection range displayed in a display unit and makes the focus detection range during shooting preparation operation within the range of the focus detection display frame.
