Abstract
An image pickup device that picks up an image of a direction not visible from a vehicle that is about to enter an intersection, and transmits the picked-up image to the vehicle is installed in the vicinity of a blind intersection. In addition, an in-vehicle device that receives the image from the image pickup device, and displays the image on a display device is mounted in the vehicle. The in-vehicle device retrieves an image pickup device identification number of an image pickup device installed at the intersection that the vehicle is about to enter and transmits the retrieved image pickup device identification number to the image pickup device and, only when an image pickup device identification number received from the image pickup device together with an intersection image and the retrieved image pickup device identification number match with each other, the in-vehicle device displays the received intersection image.
