Enhancing image quality of an initial full image of a document includes subdividing the initial full image of the document into a number of segments, directing a user to take photographs with a smartphone to provide a separate segment image for each of the segments by presenting on a screen of the smartphone a view of the document having lines superimposed thereon corresponding to the segments, and merging the separate segment images to provide an enhanced full image. The number of segments may depend upon a size of text in the initial full image and a desired height of text in the enhanced full image. The initial full image may be provided by a photograph taken by the user with the smartphone. The view of the document having lines superimposed thereon corresponding to the segments may provide a target to the user for photographing the segments.
