To prevent false detection of a stop line when determining the stop line from a luminance difference of a road surface.SOLUTION: A camera unit 2 has a camera portion 11 and a preceding driving environment recognizer 13. The preceding driving environment recognizer 13 obtains a luminance difference of a road surface from an image acquired by the camera portion 11, detects section line(s) intersecting a stop line candidate when a stop line candidate is detected from the luminance difference of the road surface, examines whether or not a portion sandwiched between dark portions is detected in a preset search range of the section line, and determines that the stop line candidate is not a stop line when the portion sandwiched between dark portions is detected.SELECTED DRAWING: Figure 1

    【課題】路面の輝度差から停止線を判定するに際し、停止線の誤検出を防止できるようにする。【解決手段】カメラユニット2は、カメラ部11と前方走行環境認識部13とを有し、前方走行環境認識部13は、カメラ部11で取得した画像から路面の輝度差を求め、この路面の輝度差から停止線候補を検出した場合、この停止線候補に交差する区画線を検出し、この区画線の予め設定されている検索範囲に、暗部の狭間が検出されたか否かを調べ、暗部の狭間が検出された場合、停止線候補は停止線ではないと判定する。【選択図】図1
