The present invention is provided with a data analysis unit 11 that, on the basis of data from an outside recognition unit 32 provided to a vehicle, acquires from among previously stored recognition models a model approximate to a recognition model recognized by the outside recognition unit 32, and that reproduces the acquired model in the form of computer graphics images. The data analysis unit 11 is provided with: a difference extraction unit 114 that compares the reproduced computer graphics images and data from the outside recognition unit 32 and extracts a difference therebetween; an object recognition unit 116 that recognizes an object relating to the difference extracted by the difference extraction unit 114; and a scene reconfiguration unit 117 that creates computer graphics images having the object recognized by the recognition unit 116 reflected therein.
