ABSTRACT:
A method for digitally magnifying images applied to an electronic device includes the steps of: reading in a preview image inputted into the electronic device; executing a 2-fold image magnifying process to the preview image; executing a fuzziness removing process to the preview image; segmenting the preview image into a background area and a text area, executing a correspondingly text strengthening process to the text area; and determining if the preview image is magnified up to a predetermined amplification factor; if yes, outputting the preview image after being magnified to a display screen for displaying the preview image; and otherwise, going back to re-execute the 2-fold image magnifying process to the magnified preview image, and then executing the fuzziness removing process and the text strengthening process, in order to generate the preview image magnified about 4-fold or more.
