Abstract
An in-vehicle white line recognition apparatus is disclosed. Form an image captured by a camera, the apparatus extracts multiple white line candidates including a first white line candidate and a second white line candidate. The apparatus calculates a certainty factor of each white line candidate, the certainty factor indicating a degree of certainty that the each white line candidate represents the white line. When the first and second white line candidates are within a predetermined range and when a ratio of contrast of the first white line candidate to that of the second white line candidate is less than a predetermined value, the apparatus decreases the certainty factor of the first white line candidate.
