PROBLEM TO BE SOLVED: To eliminate deviation between an impression of an observer who sees a real object and that of an observer who sees an object in a video. SOLUTION: In the system, video light is emitted from a projector 2 and displayed to a screen 1 and a virtual reality video including an object is displayed in a virtual reality space. The system is provided with: a real object 11 having prescribed real length; real object observation openings 12 for allowing the observer to observe the real object 11; and VR object observation openings 13 for allowing observation of the real object 11 in the virtual reality space by displaying a virtual reality video including the real object 11. A position relation between the real object 11 in the virtual reality space and the VR object observation openings 13 is the same as a real position relation. When the observer inputs the length of the real object 11 in the virtual reality space observed through the VR object observation openings 13 to a size input part 14, a scaling ratio of the virtual reality video to be displayed on the screen 1 is operated by an operation device 3 on the basis of the input length and a prescribed real length of the real object 11.
