A road environment recognition system includes an imaging device 21 configured to capture a view in a traveling direction of a vehicle, and an electronic control unit 1. The electronic control unit 1 includes: an image processing region calculation unit configured to set a predetermined region from an image captured by the imaging device 21 as an image processing region, the predetermined region including a central part and at least a part of a characteristic object present on a road, if any, in a traveling direction of the vehicle, and to decrease the image processing region, as the vehicle approaches the characteristic object; and a characteristic object detection unit configured to detect the characteristic object based on image information of the image processing region. For example, the image processing region calculation unit sets a region, which has a predetermined angle with the central part being defined as a center, as an image processing region. |
