Abstract: The image processing device counts the number of lane marking feature points. The image processing device determines whether the count number of the lane marking feature points is equal to or greater than a first threshold. The image processing device arranges the setting to use the lane marking feature points in the lane marking detection process when the count number of the lane marking feature points is equal to or greater than the first threshold. On the other hand, the image processing device counts the number of Botts' Dot feature points when the count number of the lane marking feature points is smaller than the first threshold. The image processing device arranges the setting to use the Botts' Dot feature points in the lane marking detection process when the count number of the Botts' Dot feature points is equal to or greater than the second threshold.

Abstract: An image processing apparatus includes an image acquisition unit and a determination unit. The image acquisition unit uses a camera to acquire a first image representing an area in a first relative position and a second image representing an area in a second relative position closer to the moving direction of the vehicle than the first relative position. The determination unit compares the first image with the second image acquired earlier than the first image and representing an area overlapping the first image for luminance and/or the intensity of a predetermined color component to determine whether there exists a specific area higher in luminance than the surroundings or lower in luminance than the surroundings in the first image.
