Abstract

The invention provides a display method and a corresponding display device thereof. The display method comprises the following steps: the geographic position of a target and the scale of the target in a first display area of a screen are extracted; a first map containing the target is displayed at the first display area in the scale of the target, and is served as a base map; a second map containing the target is displayed at a second display area of the screen in a maximal scale in a superimposed manner; and the first display area is larger than the second display area. The display device comprises a map data base, an extraction unit, a display processing unit and a display unit. The invention provides a display method and a corresponding display device which are used to watch the global information and partial detailed information of the image by a user. During the image display process, the image displayed by the display method or the display device can be switched among the optional scale, the maximal scale, and the combination of the optional scale and the maximal scale, thereby meeting the different watching requirements of users.

Description

technical field [0001] The present invention relates to a display method and a display device, and more specifically, the present invention relates to a display method and a display device capable of simultaneously displaying the same image at two different scales. Background technique [0002] With the increasing popularity of automobiles, vehicle navigation technology has also developed rapidly. In common navigation software, the scale of the general map is fixed during the navigation process to facilitate guidance. The zoom function of the navigation map basically needs to be triggered by user operations. [0003] Often when the speed of the car changes greatly, the user may need a different map display experience. For example, when the speed of the vehicle is slow, the user needs to enlarge the scale of the map so as to easily see the road conditions and POI (abbreviation of Point of Interest) information next to his parking space; when the speed of the vehicle is fast...
