Abstract
A device for creating a panoramic image from a plurality of images taken by a digital camera. The device comprising: an input for receiving a current image which is updated in real time when a digital image capture mechanism coupled to the input is repositioned. The device further includes a preview generator for warping or mathematically adjusting perspective of a portion of a stored previous image so as to generate an overlap portion for optimal alignment by a user of the overlap portion to the current image therewith. The warped overlap portion of the stored previous image along with the current image is presented to a viewfinder. In an alternate embodiment, a method and computer readable medium corresponding to the above system is described.
