Abstract
In an intersection information provision system, multiple cameras are installed oriented towards the direction where each road extends from the intersection. Each camera captures as an image or video the state ranging from the intersection to each road. Therefore, the area of the captured image by each camera is narrowed down. When this captured image is displayed in a display unit of a navigation apparatus in a vehicle, the driver of the vehicle can perform safety check easily. Furthermore, according to the traveling direction of the vehicle at the intersection, a display pattern of several captured images to be displayed is determined. According to the determined display pattern, multiple captured images are displayed in order. Therefore, image information required to pass through the intersection safely can be offered without shortage to the driver of the vehicle.
