To provide a lane mark recognition device that can improve recognition accuracy of lane marks of a specific color.SOLUTION: A lane mark recognition device acquires information on a lane mark on a road surface from a parallax image acquired from images captured by an in-vehicle stereo camera device (a camera device having an image sensor with a RCCC layer) 101, acquires a percentage of a first color component (e.g., yellow component) of the road surface area estimated based on the information on the lane mark, and changes a threshold for recognizing a second color component (e.g. yellow component) of the lane mark based on the percentage of the first color component (e.g. yellow component).SELECTED DRAWING: Figure 3

    【課題】特定の色のレーンマークの認識精度を向上させることのできるレーンマーク認識装置を提供する。【解決手段】車載ステレオカメラ装置(RCCCレイヤを持つ撮像素子を有するカメラ装置)101により取得された画像から得られる視差画像から路面上のレーンマークの情報を取得し、前記レーンマークの情報に基づいて推定された路面領域の第1の色成分(例えば黄成分)が占める割合を取得し、前記第1の色成分(例えば黄成分)の割合に基づいて、前記レーンマークの第2の色成分(例えば黄成分)を認識するための閾値を変更する。【選択図】図3
