1. An imaging apparatus comprising:
at least one memory and at least one processor which function as a plurality of units comprising:
(1) an acquisition unit configured to acquire a representative brightness of a high brightness region of an image;
(2) a setting unit configured to set a target brightness of the high brightness region, based on a display brightness of a display device that displays the image;
(4) an exposure control unit configured to control exposure based on the representative brightness and the target brightness of the high brightness region; and
(5) a correction unit configured to perform gradation correction, based on the target brightness and a dynamic range of a scene in which the image has been captured,
wherein the dynamic range is expressed by a number of steps, which increases in stages in accordance with a width of the dynamic range, and
wherein the correction unit performs the gradation correction in a case where the dynamic range has a predetermined number of steps or more, and does not perform the gradation correction in a case where the dynamic range has less than a predetermined number of steps.
