Abstract:
1. A vehicle equipped with: an imaging means; an image processing system which performs image processing on the basis of a road surface image captured by the imaging means; and a vehicle running condition control system which controls a running condition of the vehicle on the basis of a result of the image processing performed by the image processing system, wherein the image processing system includes: a first processing unit which searches for a first small area composed of high-luminance pixels and satisfying eligibility conditions and a second small area composed of low-luminance pixels and satisfying eligibility conditions; and a second processing unit which recognizes lane edges of a lane along which the vehicle travels on the basis of the first and second small areas found by the first processing unit; wherein the high-luminance pixels with a luminance equal to or higher than a light threshold value have a higher luminance than a first luminance of the road surface image, and the low-luminance pixels with a luminance equal to or lower than a dark threshold value have a lower luminance than a second luminance of the road surface image, and wherein the eligibility conditions are those on the size, the size and shape, the size and arrangement, or the size, shape, and arrangement in the road surface image.
