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 the wireless device or sent to a requesting entity. The scene may include a familiar landmark, a street sip or a coded sip with location information. Additionally, the scene may include an optical source transmitting an optical signal with location information.

L'invention concerne un dispositif de capture d'images dans un dispositif sans fil, aidant à déterminer la position du dispositif sans fil au moyen de techniques d'imagerie. Un lieu est sélectionné ; une image de ce lieu est créée et cette image est ensuite traitée pour permettre de déterminer des informations de position sur la base de ladite image. Ces informations de position sont ensuite affichées sur le dispositif sans fil ou envoyées à une entité requérante. Le lieu peut comporter un point de repère familier, une plaque de rue ou un signe codé avec des informations de position. En outre, ce lieu peut comporter une source optique émettant un signal optique avec des informations de position.
