<p>An auxiliary video warning device for vehicles has multiple video extracting elements for extracting video images around a vehicle. Using a video switch unit, selected video signals are sent to a vehicle display to enlarge the driver's view. A video identifying unit analyzes images outside the vehicle from a certain perspective, determining whether there is any moving object and whether its distance is changing. The result is used to automatically set off an alarm to notify the driver. During the motion of the vehicle, if any vehicle in a neighboring lane changes lanes or crosses lines illegally, an alarm is sent to the driver for better safety.</p> |
