Abstract
A digital imaging device is operated to capture a first image in a digital format. At least two non-contiguous portions of the first image are rendered in a display of the digital imaging device. The at least two non-contiguous portions of the first image are used to align a live version of a second image in the display, wherein the second image is an extension of the first image. The second image is captured in a digital format. A corner matching algorithm is applied to determine an offset of the second image with respect to the first image, wherein the offset is required to achieve a substantially accurate alignment of the first and second images. Application of the corner matching algorithm is limited to an overlap region intervening between the at least two non-contiguous portions of the first image.
