Abstract

The invention concerns a method and a device for displaying surrounding objects on a display surface 1. A first number of objects within selected geographic surroundings are displayed in perspective view 2 on the display surface. Objects that are located outside of the selected geographic surroundings, but within a predetermined distance, are represented by symbols 5 that are displayed in a frame 3 on the periphery of said display surface 1. The placements of the symbols 5 along this frame 3 provide a two-dimensional representation of the actual positions of the objects.

Claims

1. A method for displaying surrounding objects on a display surface, comprising:

displaying a first number of objects within selected geographic surroundings in perspective on the display surface,

representing a second number of objects outside of said geographic surroundings, but within a predetermined distance, by symbols in a frame on the periphery of said presentation surface, and

providing a two-dimensional representation of the actual positions of the objects based on placement of the symbols in the frame.

2. A method according to claim 1, wherein symbols representing nearer objects are displayed with greater prominence relative to objects further away.

3. A method according claim 1, wherein the symbols are displayed in accordance with their direction.

4. A device used in an aircraft to display objects surrounding said aircraft, comprising:

means for displaying a first number of objects within selected geographic surroundings as symbols in a perspective view on a display surface,

means for arranging a frame on the periphery of said presentation surface, the frame is being a representation of a selected environment outside of said geographic surroundings, and

means for generating symbols in the frame for representing objects in the selected environment outside of said geographic surroundings.

5. A device according to claim 4, wherein the frame is semi-transparent and superimposed over the perspective view.
