Abstract
In a navigation device (Unv), a processor reads directional object data (Ddr) from a storage onto a working area . The directional object data (Ddr) has a message plane and a plain plane, thereby representing a directional object whose planes are each facing in a different direction. Based on the positional relationship between the user's current position and the directional object, the processor determines whether to render the message plane or the plain plane of the directional object. In the case of the message plane, the processor renders it opaque. On the other hand, the processor renders the plain plane transparent or translucent. In this manner, the resulting display image data generated by the navigation device (Unv) can represent maps meeting the user's demands and needs
