    • An information providing apparatus allowing appropriate confirmation of contents of information which assists travel of a mobile object, presented by an image display section, even when the image display section providing information which assists travel of the mobile object as an image display is placed under a condition producing vibration not smaller than a predetermined level. The equipment has an image display section (22) mounted in a vehicle and allowing image display of information which assists travel of the vehicle, a vibration sensor (44) detecting vibration not smaller than a predetermined level produced on the image display section (22) and sending a detection output signal, and an operation control section (30) modifying a display mode of information presented as an image display by the image display section (22), into the one having contents of the information are more readily recognizable, when the detection output signal from the vibration sensor (44) expresses that the image display section (22) is in a vibration-sustained state in which vibration not smaller than a predetermined level is sustained over a duration of time not shorter than a predetermined duration.

    • A map display unit is provided with a set uni that sets a rule for extracting map information from a storage device. The set unit sets a first rule for most preferentially extracting map information on the largest scale and a second rule for most preferentially extracting map information on a specified scale. For this reason, if the first rule is set, a map on the largest scale having detailed information can be displayed, even if a map were switched. Therefore, the accuracy of route guidance can be enhanced by displaying a map suitable when passing through complicated geographical features or city. On the other hand, if the second rule is set, an arbitrary scale can be specified. For example, if a map on the smallest scale is specified, it can overlook a wide range of area and therefore the entire planed route can easily be grasped.
    • 地图显示单元设置有设置用于从存储设备提取地图信息的规则的集合单元。 设置单元设置用于最优先提取最大比例的地图信息的第一规则和用于以优先提取指定比例的地图信息的第二规则。 因此,如果设置了第一规则,即使切换地图,也可以显示具有详细信息的具有最大尺度的地图。 因此,通过在通过复杂的地理特征或城市时显示适合的地图,可以提高路线引导的准确性。 另一方面,如果设定了第二规则,则可以指定任意比例。 例如,如果指定了最小尺度的地图,则可以忽略广泛的区域,因此可以容易地掌握整个计划路线。

    • A group of maps corresponding to the present position detected by a position detection unit is retrieved from a storage unit. Also, a map on the same scale as a map being displayed is extracted from the retrieved group of maps. If there is an overlapped portion between the extracted map and the map being displayed, they are displayed with the overlapped portion held. With this, both the map being displayed and the extracted map can be displayed as if they were continuous to each other, and the present-position mark can be displayed without being jumped considerably.
    • 从存储单元检索由位置检测单元检测到的与当前位置对应的一组地图。 此外,从所检索的地图组中提取与正在显示的地图相同尺度的地图。 如果提取的地图和正在显示的地图之间存在重叠部分,则显示其重叠部分被保持。 由此,显示的地图和提取的地图都可以如同彼此连续地显示,并且可以显着地显示当前位置标记而不会相当大的跳跃。

    • A screen for a rear projection type television set including a Fresnel sheet and a lenticular sheet. Horizontal diffusion of projection light is carried out by a plurality of lenticular lenses which are arranged on the incident surface of the lenticular sheet in parallel with black stripes arranged on the emergent surface of the lenticular sheet. Vertical diffusion of the projection light is effected by a plurality of spherical or aspherical lenticular lenses which are arranged on the incident surface of the Fresnel sheet in a direction perpendicular to the pitch direction of the lenticular lenses formed on the lenticular sheet. This configurations provides a large visual field angle in both the horizontal and vertical directions.
    • 一种背投式电视机的屏幕,包括菲涅耳片和透镜片。 投影光的水平扩散由布置在双凸透镜片的出射表面上的黑条平行布置在透镜片的入射表面上的多个双凸透镜进行。 投影光的垂直扩散由多个球形或非球面双凸透镜实现,所述球形或非球面双凸透镜在垂直于形成在透镜片上的双凸透镜的俯仰方向的方向上布置在菲涅耳片的入射表面上。 这种构造在水平和垂直方向都提供了大的视场角。
