Abstract
A method of correcting distortions in digital images captured by a digital camera system includes capturing a visual image with a digital camera having a camera body, converting the visual image to a digital format to form a captured digital image, determining camera angle position data by measuring relative lengths of a plurality of beams passing between the camera body and an object to be photographed, and removing distortions associated with camera angle position based on the camera angle position data to form a corrected digital image. The method further includes storing permanently both the captured digital image and the corrected digital image in a single memory, and storing the camera angle position data as a picture file header associated with the captured digital image. The camera angle position data is selectively employed to form the corrected digital image and to enable removal of corrections from a corrected digital image.
