at least one processor and at least one memory functioning as a plurality of units comprising:

(1) a detection unit configured to detect (a) a first area inside an image that corresponds to a subject and (b) a second area inside the image that corresponds to a part of the subject;

(2) a calculation unit configured to calculate a plurality of evaluation values from a plurality of information of feature points inside the image, respectively, and

(3) a control unit configured to perform control of outputting information related to a ranging area to a display unit displaying the image,

wherein the control unit performs control of outputting, to the display unit, (a) inside a display area corresponding to the first area, a selected one of (i) first information representing the second area detected by the detection unit and (ii) a plurality of second information based on the plurality of evaluation values calculated by the calculation unit, as a candidate for a ranging area corresponding to the subject, together with (b) information representing the first area detected by the detection unit, and

wherein the control unit selects the ranging area from the candidate for the ranging area corresponding to the plurality of second information displayed on the display unit based on a user operation.
