A display control device includes a determiner and a display controller. The determiner determines a recognition accuracy based on a result of a calculator. Based on a result of the determiner, the display controller controls a displayer so as to generate an image that shows a first or second graphic in which a region indicating the direction in which a predetermined object exists is displayed in a mode different from that of another region and so as to display the image on a display medium. The first graphic is generated when it is determined that the recognition accuracy is a first recognition accuracy. The second graphic is generated when it is determined that the recognition accuracy is a second recognition accuracy lower than the first recognition accuracy. A first width of the region in the first graphic is smaller than a second width of the region in the second graphic.
