Abstract
A lane departure judgment apparatus is configured to detect a lane-dividing line based on image information output from an image-capturing device that acquires an image of an area outside a vehicle, and to judge whether or not departure of the vehicle from the lane-dividing line occurs based on a distance between the vehicle and the lane-dividing line, wherein when an angle of the vehicle with respect to the lane-dividing line thus detected is constant, the distance between the vehicle and the lane-dividing line to be used to judge whether or not departure of the vehicle occurs is changed according to whether the vehicle is being driven on a road having a lane-dividing width that is greater than a predetermined width or on a road having a lane-dividing width that is smaller than a predetermined width.
