Abstract
An image capturing device of a wireless device is used to aid in location determination of the wireless device using imaging techniques. A scene is selected, an image of the scene is formed, and the image is then processed to determine location information based on the image. The location information is then displayed on tie wireless device or sent to a requesting entity. The scene may include a familiar landmark, a street sign or a coded sign with location information. Additionally, the scene may include an optical source transmitting an optical signal with location information.
