Abstract
A mobile station determines it elevation based on the determined position of mobile station and a database of elevation data. The determined elevation of the mobile station may be used to vertically position a computer generated graphics in an image produced by the mobile station. In one embodiment, the elevation of the mobile station is determined by obtaining the elevation of multiple positions that define an area around the mobile station and using the elevation at the multiple positions to calculate the elevation at the current position.

12. A mobile station comprising:
-
a satellite positioning system receiver that provides positioning data; a camera that produces image data; a wireless transceiver; a processor connected to the satellite positioning system receiver to receive positioning data, the camera to receive the image data, and the wireless transceiver; memory connected to the processor; a display connected to the memory; and software held in the memory and run in the processor to determine a latitude and a longitude of the mobile station based on the positioning data; and
to control the wireless transceiver to obtain elevation data for multiple positions that define an area that includes the latitude and the longitude of the mobile station; and
to calculate an elevation of the mobile station using the determined elevation data for the multiple positions; and
to produce an image on the display based on the image data; and
to produce computer generated information on the image displayed on the display, the vertical position of the computer generated information on the image is based on the calculated elevation of the mobile station. - View Dependent Claims (13, 14, 15, 16, 17)
