    • A route guiding apparatus provides information for a route using public transportation as an alternative to a vehicular route. In addition to searching for a vehicular route from a current location to a destination, it is determined whether the current location and the destination are within a zone in which public transportation can be used. When the current location and the destination are determined to be within a public transportation zone, a route using public transportation is searched for. Subsequently, the cost of the route using public transportation and the cost of the vehicular route are compared. When the cost of the public transportation route falls within a predetermined limit, the apparatus indicates the public transportation route. The route costs are calculated considering factors such as required travel time and ticket fees. The apparatus may also recommend public transportation when no parking is available near the destination, or based on traffic information concerning the vehicular route.
    • 路线引导装置提供使用公共交通的路线的信息作为车辆路线的替代。 除了搜索从当前位置到目的地的车辆路线之外,还确定当前位置和目的地是否在可以使用公共交通的区域内。 当前位置和目的地确定在公共交通区域内时,搜索使用公共交通工具的路线。 随后,比较使用公共交通工具的路费和车辆路线成本。 当公共交通路线的成本落在预定限度内时,装置表示公共交通路线。 路线费用是根据所需的旅行时间和机票费用来计算的。 该装置还可以在目的地附近没有停车场的情况下,或者基于关于车辆路线的交通信息来推荐公共交通工具。

    • A camera is disposed on a door mirror whose operating position is changeable between a deployed position and a retracted position, so that the positional relationship of the camera with a vehicle body changes as the operating position of the door mirror changes. A region corresponding to the operating position of the door mirror is partially extracted from the entire shot area of an image taken by the camera. That is, the angular direction of the region partially extracted from the entire shot area taken by the camera when the door mirror is in the deployed position and the angular direction of the region partially extracted from the entire shot area taken by the camera when the door mirror is in the retracted position are made different from each other by an angle equal to the angle difference between the two positions of the door mirror. The camera-taken images of the extracted regions are conformed to the screen of a display. Thus, the vehicle traveling direction appearing on the display remains unchanged regardless of changes in the operating position of the door mirror.
    • 照相机设置在门镜上,其操作位置在展开位置和缩回位置之间是可变的,使得照相机与车身的位置关系随着门镜的操作位置改变而改变。 从摄像机拍摄的图像的整个拍摄区域中部分地提取对应于门镜的操作位置的区域。 也就是说,当门镜处于展开位置时,由摄像机拍摄的整个拍摄区域部分地提取的区域的角度方向,并且当门处于展开位置时区域的角度方向部分地从照相机拍摄的整个拍摄区域中提取 反射镜处于缩回位置的方式彼此不同,角度等于门镜的两个位置之间的角度差。 提取的区域的照相机拍摄图像符合显示器的屏幕。 因此,出现在显示器上的车辆行驶方向与门镜的操作位置的变化无关。
