A technique enables intuitive understanding of a directional relationship between a photographed image and a wide area image, such as an electronic map. An image processing device includes a display controlling unit that displays a quadrangular-shaped photographic image, which is photographed from an aerial vehicle, displays a mark indicating a photographing position of the quadrangular-shaped photographic image, on a wide area image, and performs highlight display in accordance with a corresponding relationship between a direction of the quadrangular-shaped photographic image and a direction of the mark.
