To provide an image feature emphasis device, a road surface feature analysis device, an image feature emphasis method, and a road surface feature analysis method that can improve precision of feature detection on a road surface in a road surface image.SOLUTION: An image feature emphasis device according to an embodiment has a region acquisition unit and an image feature emphasis processing unit. The region acquisition unit acquires a region of a road surface part from a picked-up image. The image feature emphasis processing unit varies, based upon the highest luminance value and the lowest luminance value in the acquired region of the road surface part, a luminance value in the region of the road surface part so as to emphasize features of the region of the road surface part.SELECTED DRAWING: Figure 2

【課題】路面画像における路面の特徴検出の精度を向上することができる画像特徴強調装置、路面特徴解析装置、画像特徴強調方法及び路面特徴解析方法を提供することである。【解決手段】実施形態の画像特徴強調装置は、領域取得部と、画像特徴強調処理部とを持つ。領域取得部は、撮像された画像から、路面部分の領域を取得する。画像特徴強調処理部は、取得された前記路面部分の領域内の最高輝度値と最低輝度値とに基づいて、前記路面部分の領域内の輝度値を変更することによって前記路面部分の領域の特徴を強調する。【選択図】図２
