Similarly, a virtual vehicle of the own vehicle that parks/stops on the road shoulder 71′ is displayed as well at the second display device 4 as a moving image of a virtual image 75′ as being superimposed to the taken scenery 39. The virtual image 75′ is displayed so that the virtual vehicle travels on the arrow of the symbol image 73′ as having the arrow as the trajectory therefor. Specifically, the virtual image 75′ appears to move out frontward from a position just in front of the screen of the monitor device 24 as illustrated in FIG. 22A and moves to and stops on the planned parking/stopping space indicated by the symbol image 72′ illustrated in FIG. 22B.
