1. An image-capturing apparatus capable of adjusting an angle of view, comprising: a detection unit that detects a predetermined subject from a captured image; a setting unit that sets an area of the captured image as an auto-zooming frame, wherein the area includes a plurality of subjects selected from among the detected subjects, wherein, in a case in which at least one of the plurality of subjects moves out of a field of view that is larger than the auto-zooming frame, the setting unit sets the auto-zooming frame on a subject other than the subject that has moved out of the field of view; and a control unit that adjusts the angle of view so the auto-zooming frame can be captured.
