Patent ID: 7375745

Claim:
A method for stitching digital images together onboard a digital imaging device, comprising: capturing a first image in a digital format; displaying at least two non-contiguous portions of the first image in a display of the digital imaging device, wherein the at least two non-contiguous portions of the first image are separated from each other by an intervening live region of the display; using the at least two non-contiguous portions of the first image to align a live version of a second image in the display, wherein the second image is an extension of the first image; capturing the second image in a digital format; and applying a computer implemented corner feature matching algorithm to determine an offset of the second image with respect to the first image required to achieve a substantially accurate alignment of the first and second images, wherein application of the computer implemented corner feature matching algorithm is limited to an overlap region of the first and second images present between the at least two non-contiguous portions of the first image, wherein a corner feature is defined by a limited pixel are within which large contrast changes exist between pixels in both horizontal and vertical directions.
