Abstract: An image scanning apparatus with scan-starting point positioning function comprising a casing, a carriage and a calibration sheet is provided. Of which, the casing comprises a scan-platform used to place documents to be scanned, while the calibration sheet, which is fixed to the inner surface of the carriage and lies between the home line of the carriage and the upper wider margin of the scan-platform, comprises a hollowed-out mark completed through a punch-cutting manufacturing process. The mark can be defined using a predefined function set and has a reference point. After the carriage has moved to a scan line, the reference point can be located according to the intersection points between the mark scanned and the scan line accompanied by the predefined function set of the mark. Of which, the calibration sheet and the inner surface of the casing are of different levels of brightness.

Abstract: A method for constructing a Gamma table to perform Gamma correction according to the Gamma table. First, select (2M+1) major sampling pixel data, which divide a Gamma curve into 2M major segments. Next, obtain the maximum difference between the n-th major sampling line and the n-th major Gamma segment; according to the maximum difference, select (2Rn−1) minor sampling pixel data from the n-th major Gamma segment. Last, store the Gamma corresponding relationship of all major and minor sampling pixel data in the Gamma table. The execution of Gamma correction includes the following steps. First, select the a-th major sampling pixel datum according to the first M bits of an input pixel datum. Next, select the b-th and the (b+1)-th minor sampling pixel data according to the (M+1)-th bit to the (M+Ra)-th bit of the input pixel datum. Finally, obtain the Gamma corresponding relationship of the input pixel datum via interpolation using the b-th and the (b+1)-th minor sampling pixel data.

Abstract: An apparatus for positioning a scanning starting point of an image scanning apparatus includes a platen, carriage, and a number of marks. The X-Y coordinate system defined by the platen has an X-axis defined by a first wide margin of the platen and a Y-axis defined by a first long margin of the platen. The carriage moves along the Y direction. The marks inside the image scanning apparatus indicate different Y coordinate values. The method for positioning a scanning starting point of an image scanning apparatus is as follows: the nearest mark to the document to be scanned is first chosen as a reference point. The vector from an image starting point of the document to be scanned to the reference point is then obtained. The carriage finally moves to the reference point chosen as a starting point and proceeds to scan.
