Abstract

The invention relates to a map display technology, and particularly relates to a map display method, a map display device and a computer readable medium. The map display method comprises the steps ofobtaining ambient brightness; determining a transparent value of a map image according to the ambient brightness, wherein the transparent value is positively related to the ambient brightness; and obtaining map data; and displaying the map image according to the map data and the transparent value. According to the map display method and device, the problem that a user cannot observe an electronicmap due to the influence of sudden change of screen brightness can be solved.

Description

technical field [0001] The present invention relates to map display technology, in particular to a map display method, a map display device, and a computer-readable medium. Background technique [0002] A map is an image symbol model or graphical mathematical model that reflects the objective reality with certain mathematical rules (ie patterning), symbolization, and abstraction. According to certain mathematical rules, the map reflects the natural and human phenomena on the earth (or other planets) in a reduced size on the plane by using the language of the map and through cartographic synthesis, so as to reflect the spatial distribution, combination, connection, and quantity of various phenomena. and quality characteristics and their evolution over time. [0003] At present, thanks to the wide application of electronic devices such as computers and mobile phones in cartography, maps are no longer limited to symbols and graphics expressed on paper (or similar media), but c...
