Abstract
An edge image generating unit 12 generates an edge image 22, into which edge points whose variation in luminance relative to a surrounding portion is equal to or more than a predetermined value have been extracted, from an image 21 captured by a camera 2. A candidate image portion extracting unit 13 extracts a candidate image portion, which is a candidate for an image portion of a dashed-line lane mark, from the edge image 22. A dashed-line lane mark recognizing unit 14 recognizes the dashed-line lane mark based on a plurality of candidate image portions each of whose length in the corresponding real space is within a predetermined range and which are continuous in a given direction among the candidate image portions.
