A system and method are directed towards enabling centralized registration for managing a selective display of visitor information to distributed social networking websites. The image processing units 7, 8 detects moving objects, such as vehicles traveling alongside a host vehicle provided with the vehicle surroundings monitoring apparatus, and oncoming vehicles, on the basis of optical flow between two images taken by the cameras at different times, respectively, and sets a representative point representing the detected moving object on the surface of a road. Then, the navigator data is compared with the map data to generate comparison data. This invention also provides a photographic element which contains a magnetic recording layer which has excellent magnetic characteristics and which is substantially photographically transparent by virtue of its low granularity and optical density.
