PURPOSE:To set a processing area so that an obstacle such as a front running vehicle on a picture does not influence traveling lane recognition, and to prevent the traveling lane recognition from being mistaken by providing a picture processing inhibition area setting means, etc., to set a picture processing inhibition area on image-picked up picture data on the basis of the position information of the obstacle. CONSTITUTION:The output of a radar unit 12 is stored in a memory 34 for communication through a radar processing circuit 40 and a bus 32, and a radar evaluation CPU 42 reads a stored value at every prescribed time, and detects the position of the obstacle on the coordinates. Then, the picture processing inhibition area is set on the picture data image-picked up by a CCD camera 10 by the picture processing inhibition area setting means on the basis of the position information of the obstacle, and besides, the picture data located outside the picture processing inhibition area is processed by a picture processing means, and information a traveling lane shows is outputted. Thus, even though the obstacle such as the front running vehicle enters the field of view of the CCD camera 10, it never overlaps the processing area, and therefore, the traveling lane recognition is never mistaken. |
