Abstract

A distance detection device mounted on a vehicle and the driver of the vehicle can recognize an obstacle in front of him through the device on the road on which he is driving. The device is electronic with a TV camera, memory and CRT. Those units enable the drive not only to recognize an obstacle on the road, but also to know the distance from his vehicle to an obstacle in front of him such as another vehicle.
