A road is modeled using the lane border, and an actual road width is calculated according to a distance between pixels on an image coordinate using a camera parameter calculated in accordance with a position of a camera. Then it is determined If the vehicle is moving out of the lane or not; and an alarm is produced when the vehicle is moving out of the lane.
