1. A three-dimensional object detection device comprising:

  • an image capturing unit having a lens for capturing images of an area rearward of a host vehicle;

    a three-dimensional object detection unit programmed to detect a presence of a three-dimensional object in a predetermined detection area, based on the images captured by the image capturing unit, and programmed to calculate a traveling speed of the three-dimensional object;

    a host vehicle speed detection unit programmed to detect the traveling speed of the host vehicle;

    a light source detection unit programmed to detect a headlight light source corresponding to a headlight of another vehicle, within a predetermined light source detection area that includes the detection area; and

    a controller programmed to compare the traveling speed of the three-dimensional object and the traveling speed of the host vehicle upon the headlight light source not being detected by the light source detection unit, and programmed to perform a control process to suppress detection of the three-dimensional object upon determining one of the traveling speed of the three-dimensional object being equal to or less than the traveling speed of the host vehicle, and a difference between the traveling speed of the three-dimensional object and the traveling speed of the host vehicle being less than a predetermined value.
