Abstract: The present invention provides a method and apparatus for calculating position information of an image captured by an imaging device, the method including capturing the image by an imaging device; determining whether position information is available; measuring a movement direction and a velocity of the imaging device, when the position information is not available; re-determining whether the position information is available; selectively acquiring a current reference point using the position information, when the position information is now available; and calculating the position information corresponding to the image based on the movement direction, the velocity, and the current reference point.
