Abstract

A scanner capable of providing extra position information and an image calibrating method are provided. The scanner can generate images with extra position information by scanning a reference pattern while scanning document. The reference pattern is positioned on the bottom face of the top housing near the scanning platform or is printed on a template, which is placed on the scanning platform. The image calibrating method calibrates the position for the images, which are scanned from a same document, by the extra position information. The image calibrating method comprises the steps of: calculating the reference coordinates (x1, y1) and (x2, y2) according to the extra position information for each image, calculating the distance (Deltax, Deltay) between the two reference coordinates and calibrating the images according to the distance (Deltax, Deltay).

That is, align the second image data The image data (or the first image data) is moved by the distance from the coordinate offset (△ X, A y). Figure 6 (B) shows the corrected image data. In addition to the correction result, the system can process the image during the scanning process. In addition to the problems caused, and the positions of the images after multiple scans can be consistent, the effect is quite significant after repeated experiments, which can effectively correct the time shadows during scanning. The positioning error enables subsequent image processing. Although the method of positioning the image data of the present invention has been described by way of example, the scope of the present invention is not limited by this. As long as it does not deviate from the gist of the present invention, those in the industry can make various modifications. For example, although in the embodiment the correction of the image data is performed by using the image data of the reference pattern scanned twice, the determination of the coordinate of the image data of the parent scan can also be corrected.

The image data positioning method described in item 4 of the scope of the patent application, wherein the step of correcting image coordinates is to shift the aforementioned second image data by a relative coordinate offset (△ X, △ y). 第16頁Page 16
