  • Patent number: 7751970
    Abstract: To safely and easily provide information that an operator needs, when a mobile body has started to move, a first acquiring unit and a second acquiring unit respectively acquire corresponding image information. Using the acquired image information and map information, an extracting unit extracts map information identical to the image information of the scenery around the mobile body. A selecting unit selects, from the extracted map information, an object that coincides with the position of the point viewed by the operator in the image information of the scenery around the mobile body. An output unit outputs information concerning the selected object.
