摘要： The present disclosure discloses methods, systems and scanners for scanning document with varying light intensity. The method includes receiving a bound document positioned on an upper surface of a platen, for scanning, wherein the bound document, when opened for scanning, includes a flat region and a curved region. A distance between the bound document positioned on the platen and a contact image sensor (CIS) is continuously monitored and measured, to detect the curved region. Upon detection, a control command is generated to vary the intensity of the light to be emitted from a light source. Then, light with varying intensity is emitted for illuminating the curved region of the bound document. Thereafter, the light reflected from the bound document is received for capturing an image of the bound document. Finally, a digital version of the bound document is generated without any dark strip or without any distortion.

摘要： The disclosure discloses methods and systems for intelligent copying of bound documents. The method includes receiving a selection of copying a bound document via a user interface. The user interface is presented to the user to input whether a starting page of the bound document for copying is a left-side page or a right-side page. Then, multiple pages of the bound document are scanned to generate corresponding scanned images. Finally, the generated scanned images are arranged in the same order as per the arrangement of pages in the original bound document.
