    • PROBLEM TO BE SOLVED: To provide a navigation technique with high visibility and availability, which can appropriately vary the position of a view point and/or a depression angle in 3D displaying, in response to the class of a road on which a user currently travels, or its traveling state.
      SOLUTION: A navigation system searching a route for guiding, along which a mobile object moves from its departure place to a designated destination, on the basis of road map data previously storing data representing classes of roads to be prepared, is equipped with a current position detecting section 40 which detects the current position of the mobile object; a traveling road class recognizing section 43 which recognizes the class of the current traveling road, based on the road map data and the current position; a view point positioning section 44 which adjusts the position of the view point in displaying on a screen, based on the recognized class of the road; and a display control section 46 which varies the displaying on the screen in accordance with the position of the view point determined by the view point positioning section 44.

    • PROBLEM TO BE SOLVED: To secure safety so as to avoid an obstacle for driving and to prevent a driver from receiving discomfort at displaying of an image related to an institution superimposed on a real scenery.
      SOLUTION: The image display device for vehicles displays the institution-related image about the institution, in order to make the information related to the institution existing in front of the vehicle visible in superimposed on the real scenery, which is visible through a window from the driver of the vehicle in order to provide the driver with such information. The display control is performed in a display format such that the prescribed institution related image is displayed, when the institution is visible and that the prescribed institution-related image is not displayed, when the institution is not visible. At this time, the display of the simple image indicating the position of the institution and the detailed image explaining the attribute of the institution as the institution-related image is possible.

    • 要解决的问题:为了确保安全性,以避免驾驶障碍,并且防止驾驶员在显示与叠加在真实风景上的机构有关的图像时感到不适。

      解决方案:车辆的图像显示装置显示与该机构有关的机构相关图像,以便使与车辆前方有关的信息可以叠加在真实风景上可见的信息,其可通过 窗口从车辆司机向司机提供这样的信息。 当机构不可见时,机构可见并且没有显示规定的机构相关图像的显示格式进行显示控制,使得规定的机构相关图像被显示。 此时,表示机构的位置的简单图像的显示以及将机构的属性解释为机构相关图像的详细图像是可能的。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To correct altitudes of grid points by depending on altitudes of one or more specific points nearby. SOLUTION: A searching part 41 in a program 40 detects a plurality of proximity points on a pair of contour line point sequences in respect to slope land grid points positioned between contour line point sequences with two different altitudes, and an altitude calculation part 42 determines the altitudes at the grid points on the basis of the positions and altitudes of these proximity points. A correction altitude determining part 43 determines altitudes of the grid point corresponding points corresponding to correction-targeted slope land grid points which should be positioned nearby the slope land specified points in respect to the correction-targeted slope land grid points, wherein the correction-targeted slope land grid points are positioned nearby at least one slope land specified point positioned between the pair of contour line point sequences and positioned between the pair of the contour line point sequences. And the determining part 43 determines the corrected altitudes of the correction-targeted slop land grid points by depending on the attributes of the grid point corresponding points and the positional relationship between the grid point corresponding points and the correction-targeted slope land grid points.
