The outside environment recognition in front of the direction of a first image is obtained in a first exposure mode according to a brightness value of an external surroundings and receives a second picture in a second exposure mode, the exposure time of that of the first exposure mode, and makes it possible to determine whether a light source emits light by itself or not. The outside environment recognition in front of the direction of the identified, based on the first image, an area of the vehicle the from a preceding vehicle is taken up in a detection range of, in a position of the light source on the basis of the luminance of the second image, and assigns the position of the light source and the region of the vehicle to.
