    摘要： A sheet-fed scanning device capable of detecting a document edge includes a scanning module and an automatic document feeder. The scanning module scans a document with a light ray. The automatic document feeder feeds the document across a scanning region on a sheet passageway for the scanning module to scan. In this invention, a section of a guide plate of the sheet passageway located within the scanning region is formed with a concave portion, wherein the document moving across the scanning region is located between the concave portion and the scanning module, such that the intensity of a first brightness of the concave portion sensed by the scanning module is far smaller than the intensity of a second brightness of the document sensed by the scanning module. Thus, it is possible to facilitate the document edge detection and the document skew correction.

    摘要： One method for determining a gray background value of a scanned document having left, right, top and bottom edges includes obtaining a scanned image of a horizontal strip which includes at least one portion of the document and which includes at least one non-document area, and includes creating a histogram of pixel values, of the horizontal strip, inside the document edges while excluding from the histogram pixel values, of the horizontal strip, located outside the document edges. Another method for determining a gray background value includes obtaining a scanned image of a vertical strip. One method for determining skew of a scanned document includes obtaining a scanned image, which includes a leading document edge, using vertically-displaced successive horizontal scan lines, includes determining points of the leading edge, and includes fitting a line to the points. Another method for determining a skew uses horizontally-displaced successive vertical scan lines.
