To solve the problem in which road signs previously detected cannot be properly translated via simple operations while a car is moving.SOLUTION: A road sign display device includes: a sign image database which stores road sign images for each region; an image recognition unit which recognizes a road sign located ahead of a moving vehicle; an obtaining unit which obtains a region in which the vehicle is moving; an identification information management unit which creates identification information indicating that the road sign has been recognized by the image recognition unit while the vehicle is moving; an operation unit for instructing to start translation of the road sign according to user operation; and a display control unit which, if the identification information has been created when the user operation is performed, reads out from the sign image database and display a road sign image of a pre-set region which corresponds to a recognition image with which the road sign has been recognized.SELECTED DRAWING: Figure 1

    【課題】車両走行中に過去に認識した道路標識を簡単な操作で適宜翻訳することができない。【解決手段】道路標識画像を地域別に記憶した標識画像データベースと、車両の進行方向に位置する道路標識を認識する画像認識部と、前記車両の走行地域を取得する取得部と、前記車両の走行中に前記画像認識部で前記道路標識が認識されたことを示す識別情報を設定する識別情報管理部と、前記道路標識の翻訳開始をユーザ操作により指示する操作部と、前記ユーザ操作がなされた場合に、前記識別情報が設定されていれば、前記道路標識を認識した認識画像と対応する予め設定された地域における前記道路標識画像を前記標識画像データベースより読み出して表示する表示制御部とを備える道路標識表示装置。【選択図】図1
