  • Publication number: 20140009618
    Abstract: A lane departure warning device includes: a compartment line detection unit that detects a compartment line in an image of a running lane on which a vehicle is traveling, the image being captured by an image capturing device which the vehicle has; a dirtiness detection unit that detects dirtiness on any one of a lens of the image capturing device or a partition between an outside of a vehicle interior of the vehicle and the image capturing device; a departure judgment unit that judges whether or not the vehicle departs from the compartment line; and a warning judgment unit that when it is judged that the vehicle departs from the compartment line, outputs a warning signal based on a degree of the dirtiness detected. A position of the vehicle with respect to the compartment line when the warning signal is output varies depending on the degree of the dirtiness.
