| 摘要 |
The invention relates to a method for using portable electronic equipment, which comprises a digital camera or can be used with a digital camera, to scan a surface containing text and/or drawings or sketches. According to the method, a digital photograph, which comprises the surface to be scanned, is taken with the digital camera of the electronic device. The text and/or drawings or sketches of the surface to be scanned are transferred to a digital image file, maintaining both their own and their mutual spatial arrangement. The effects that appear during the creation of the photograph comprising the surface to be scanned and that have a detrimental effect on the image, for example geometric distortion, lack of focus, blurring, shadows and/or light reflection effects, digital noise, lack of contrast and/or colorimetric shift, are removed or compensated.
