Abstract
An off-lane alarm apparatus is disclosed in which upon the increase of the height of a pickup sensor mounted on a car, the increased portion is provided for an image processing device. The image processing device then determines a necessary outside area of a predetermined lane width with other input or switched data to mask an image portion corresponding to the necessary outside area for the car's off-lane detection.
