ABSTRACT:
A white line detection apparatus comprises an extraction device that extracts an image of a white line detection processing area set within a road image captured by an image-capturing device, a maximum value estimating device that estimates a maximum value among pixel values constituting an image of road surface areas other than the white line based upon the pixel values representing the image extracted by the extraction device, a contrast reducing device that reduces the contrast of an image corresponding to pixel values equal to or lower than the maximum value among the pixel values constituting the image of road surface areas other than the white line which has been estimated and a detection device that detects the white line based upon the image whose contrast has been lowered by the contrast reducing device.
