Described herein is a run environment recognizing apparatus. The run environment recognizing apparatus comprises an imaging device for sensing the direction of traveling of a host vehicle as imaging vision, a radar for detecting the direction of traveling of the host vehicle as a detection range, an image processing device for recognizing traveling lanes, leading vehicles and stationary objects located ahead of the host vehicle, based on the image information sensed by the imaging device and the result of detection by the radar, and a display for displaying the results of recognition by the image processing device. The image processing device includes means for setting vehicle regions indicative of the leading vehicles within the image information, based on the result of detection by the radar. Thus, the influence of the leading vehicles in the process for recognizing the traveling lanes within the image information is eliminated by the vehicle regions.
