PROBLEM TO BE SOLVED: To provide a lane mark recognition device capable of improving detection accuracy of a lane mark even when there is an influence of a shadow.SOLUTION: A color determination part 14 defines, as yellow, a color of pixels on an object area of a photographed image 21 of an RGB color camera 2, under any one condition of conditions that a value of B of object area pixels within a road area presumed as a road image part is smaller than a value of B of comparative area pixels within a road area including a road image part other than the lane mark, and that a value Tobtained by subtracting the value of B from a value of R of the object area pixels is larger than a value Cobtained by subtracting the value of B from the value of R of the comparative area pixels.

    【課題】影の影響がある場合においても、レーンマークの検知精度を向上させることができるレーンマーク認識装置を提供する。【解決手段】色判定部14は、RGB方式のカラーカメラ2の撮像画像21に対して、道路の画像部分であると推定される道路領域内の対象領域画素のBの値がレーンマーク以外の道路の画像部分を含む道路領域内の比較領域画素のBの値より小さいこと及び当該対象領域画素のRの値からBの値を引いた値TR−Bが比較領域画素のRの値からBの値を引いた値CR−Bより大きいことの少なくとも1つを要件として、当該対象領域の画素の色を黄色とみなす。【選択図】図1
