A display control apparatus performs overlapping display of a highlight image against a notification object that is visually recognized through a picture projection plane of a virtual image display apparatus used by a driver of a vehicle such that the highlight image represents the notification object. A target information acquisition section acquires target information including at least a position and a size of the notification object. A display execution section displays a first highlight image and a second highlight image in a display form capable of identifying each of the first highlight image and the second highlight image based on target information acquired by the target information acquisition section. The first highlight image corresponds to a size of the notification object, while the second highlight image results from enlarging the first highlight image at a predetermined magnification percentage.
