ABSTRACT:
An apparatus that determines the presence of an element such as fog interfering with the visibility of a frontal view of an driver in an vehicle in an environmental atmosphere in ahead of the vehicle equipped with the apparatus in the daytime is provided. In this apparatus, the determination of whether the presence of the element is determined based on an image that captured by a vehicle-mounted camera and in which a picture of an obstacle located on a road over which the vehicle is traveling is masked. In the determination, a reliability of determining the presence of the element is considered by measuring the effect of masking the obstacle.
