    Abstract: An image scanner having an improved scanning quality is disclosed. Two different color blocks having an interface therebetween are provided on the document platform of the image scanner. The image pickup device passes by the color blocks prior to the document area so that color calibrations and/or error detection can be performed before the scanning operation is performed. By this way, the color data such as the brightness of the obtained image can be compensated, and the deflection rate and/or the amplification error of the image pickup device can be corrected.

    Abstract: A method for quick determination of a scan start point for an image scanner is disclosed. The image scanner includes a photo-processing device and a scanning platform for placing thereon a document to be scanned. The scanning platform is printed with a pattern mark which is located between a home position and a scan start point of the photo-processing device, and has a specified point being a predetermined first shift to the scan start point along a specific direction. According to the method, the photo-processing device moves a predetermined distance from the home position to a pre-scan position overlapping with the pattern mark, then moves a calculated distance from the pre-scan position to the specified point, and moves another predetermined distance from the specified point to the scan start point along the specific direction.

    Abstract: In a method for initializing an image scanner having a scanning module and an automatic document feed (ADF) glass, the scanning module is moved in a forward direction toward the ADF glass to search for a reference mark located within a relatively close proximity to the ADF glass. The scanning module is moved forward to search for a black-white transition in response to the reference mark being located and the scanning module is moved in a backward direction away from the ADF glass in response to the black-white transition being located. The scanning module is stopped when the image sensor of the scanning module is aligned with an origin mark to thereby accurately position the scanning module.
