1. A method of creating an image from a device, comprising: acquiring first and second images from first and second areas of the device, said first and second images having overlapping portions; estimating said overlapping portions to obtain an approximate shift amount to align approximately said first and second images; analyzing said overlapping portions, using a defined cross-correlation algorithm, to calculate a precise shift amount to align the first and second images; and using said calculated precise shift amount to join the first and second images together to form a joined image.
