Display control device for displaying combined vehicle-mounted camera images with aligned vehicle icon

The display control device displays captured images around a host vehicle captured by a plurality of vehicle-mounted cameras on a display unit. The display control device includes an image combining unit configured to combine the captured images of the plurality of vehicle-mounted cameras to generate a combined image, and an icon combining unit configured to generate a composite image by combining a vehicle icon with the combined image. The icon combining unit generates the composite image so that the imaging direction of the vehicle-mounted cameras and the orientation of the vehicle icon in the combined image are aligned when viewed from the host vehicle.
