Title: OBJECT DETECTOR
Abstract:
 Provided is an object detector making it possible to minimize any drop in accuracy of object detection under a low brightness environment such as nighttime or in tunnels, thereby minimizing failure in speed/inter-vehicle distance control, pre-crash safety systems, and the like. The object detector is provided with: a distance calculation unit (105) for calculating the distance to objects in the vicinity of the vehicle on the basis of images taken by a plurality of imaging units (102, 103); an extraction unit (106) for extracting, from among the objects in the images, an object that is at least in a distant region away from the vehicle on the basis of the distance calculated by the calculation unit (105) and is of a specific color; and an output unit (108) for outputting the distance to the object extracted by the extraction unit (106).
