    • Generation of a plurality of orthomosaic image layers for a geographical area, wherein the layers comprise different spatial resolutions and are radiometrically normalized to facilitate improved radiometric consistency when zooming relative to the geographic area. In applications that facilitate zooming with respect to a geographic area imaged by the orthomosaic layers, radiometric normalization of the orthomosaic image layers may reduce radiometric discontinuities when zooming in, zooming out, and/or panning a displayed portion that is output to the user. The orthomosaic layers may be generated based on one or more orthomosaic image layer or may be developed independently using a source images. In any regard, the radiometric normalization may include generating a normalization function based on image metadata that is calculated and may be independent of the spatial resolution of the image.
    • 生成用于地理区域的多个正交马赛克图像层,其中所述层包括不同的空间分辨率,并且被放射计量归一化,以便当相对于地理区域变焦时有助于提高辐射度一致性。 在有助于相对于由正交镶嵌层成像的地理区域进行缩放的应用中,正交镶嵌图像层的辐射归一化可以在放大,缩小和/或平移向用户输出的显示部分时减小辐射不连续性。 正交镶嵌层可以基于一个或多个正交马赛克图像层产生,或者可以使用源图像独立地开发。 在任何方面,辐射规范化可以包括基于所计算的图像元数据生成归一化函数,并且可以独立于图像的空间分辨率。

    • A navigation apparatus is provided that is highly convenient for a user to view a map screen and a menu window. A display controller 15 determines a view mode of each of a map screen and a menu window, based on information about a travel condition of a moving object from a route search unit 12 and an own-vehicle location identification unit, when the menu window is displayed according to information entered from an input unit 10. A display map generator 16 generates a map screen according to information about the view mode from the display controller 15. A display menu generator 17 generates a menu window according to information about the view mode from the display controller 15. A display unit 21 displays the map screen from the display map generator 16 and the menu window from the menu generator 17.
    • 提供了一种导航装置,其非常方便用户查看地图屏幕和菜单窗口。 显示控制器15基于关于来自路线搜索单元12和本车位置识别单元的移动物体的行驶状况的信息,在菜单窗口为“否”的情况下,确定地图画面和菜单窗口中的每一个的视图模式 根据从输入单元10输入的信息显示。显示图生成器16根据来自显示控制器15的关于视图模式的信息生成地图画面。显示菜单生成器17根据关于视图模式的信息生成菜单窗口 显示控制器15.显示单元21从显示图生成器16显示地图画面和菜单生成器17的菜单窗口。
