DIGITAL ZOOM AND PAN Problem: It was known that one can view a digital image and “zoom” (i.e., magnify a portion of an image and appearing to move into the image) and “pan” (i.e., move across or around within the plane of that image). However, prior systems have failed to produce high quality, high resolution digital images having the ability to zoom within the image and to pan around the image without pixelation. Solution: Iviewit’s answer to this problem can be generally described as a method of providing a digital image file for viewing in a viewing window of a user display, the viewing window having a predetermined size. The method includes providing a digital image having an image size comprising a fixed number of pixels representative of an image, the image size being greater than the predetermined viewing window size. The digital image file is associated with a user interface that is configured to display the digital image in the viewing window and to allow a user to zoom into and pan around in the image displayed in the viewing window while maintaining high image quality. According to one example, multiple images can be stitched together after scanning, and before or after compression, thereby creating a panoramic scene or image, or simply a scene requiring a plurality of photographs.
