An electronic device includes an eye gaze detection unit that detects a gaze position of a user, and a control unit that changes a luminance value of a background image displayed on a display unit in at least two steps. The control unit performs control to, when the luminance value is a first luminance value, change the luminance value from the first luminance value to a second luminance value after the eye gaze detection unit detects a plurality of gaze positions of the user including at least the gaze position of the user in a case where an item is displayed at a first position on the display unit and the gaze position of the user in a case where the item is displayed at a second position thereon. The eye gaze detection unit detects the gaze position of the user when the luminance value is the second luminance value.
