    • 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.
    • 拍摄从即将进入交叉点的车辆不可见的方向的图像并将拍摄图像发送到车辆的图像拾取装置安装在盲路交叉口附近。 另外,车载装置中,将从图像拾取装置接收图像并在显示装置上显示图像的车载装置安装在车辆中。 车载装置检索安装在车辆即将进入的交叉点处的图像拾取装置的图像拾取装置识别号码,并将检索到的图像拾取装置识别号码发送到图像拾取装置,并且仅当图像拾取装置 从摄像装置接收的识别号与交叉图像和检索到的图像拾取装置识别号码相互匹配,车载装置显示接收到的交叉图像。
