Abstract
A method of detecting and correcting camera rotation in a digital camera, that includes the steps of: capturing a digital image to provide a captured digital image; and analyzing the captured digital image to detect a set of lines. The set of lines are used to determine a rotation angle of the captured digital image; and the captured digital image is modified based on the rotation angle, before storing the modified digital image.
