Claim:
1. A three-dimensional object detection device comprising: an image capturing device mounted on a host vehicle, and comprising a lens for capturing images behind the host vehicle; a three-dimensional object detection unit programmed to detect a presence of a three-dimensional object in a detection area based on captured images acquired by the image capturing unit; and a nighttime assessment unit programmed to assess whether or not nighttime has fallen; a luminance detection unit programmed to detect a luminance of a plurality of image areas based on the captured image; a luminance peak detection unit programmed to detect a peak in the luminance having a luminance gradient that is greater than or equal to a predetermined reference value from among the peaks in the luminance detected by the luminance detection unit as a target luminance peak; and a controller programmed to control detection of the three-dimensional object by the three-dimensional object detection unit in an image area in which the target luminance peak is detected when an assessment has been made that nighttime has fallen by the nighttime assessment unit.
