Addition of Compass Orientation to Images as Meta-Tags

Idea: Matthias Marke, DE-Muenchen; Gerald Clemens, DE-Muenchen

Today, pictures taken by digital cameras are saved without information about the direction the camera (e.g. north, west, south or east) is pointing while photographing.

It is proposed to store the point of the compass as a meta-tag with the picture. The point of the compass can either by obtained manually by user selection or automatically by an integrated compass or GPS device. This information can for example be stored as a value pair (x, alpha), where x is the horizontal coordinate in the digitized picture and alpha is the angle between the point of the compass in the picture and a reference direction, like for example north (Fig. 1). Optionally, it is possible to store the total circular measure covered in the photographed region. This can be calculated from the lens properties and settings. With this information it is possible to show an orientation indicator as shown in Fig. 2.
