PURPOSE:To display a run visual field picture nearby an intersection where a vehicle passed once by operating the current position of the vehicle and storing intersection information and a picture of a run visual field photographed nearby the intersection together with entry direction data. CONSTITUTION:An arithmetic means operates the current position of the vehicle from the outputs of an azimuth detector and a vehicle speed sensor. The intersection information stored in the 1st storage means and the current position are inputted to a decision means, which decides whether the vehicle reaches the intersection or not, or whether the vehicle passes through the intersection or to when the vehicle already reaches the intersection. When the reached intersection is not a passed intersection, the picture of the run visual field photographed by a camera is stored in the 2nd storage means together with data on the direction of entry to the intersection. Further, when the intersection is a passed intersection, data stored in the 2nd storage means is displayed on a display means. |
