Embodiment Construction

[0031] Preferred embodiments of the present invention will be explained in detail below with reference to the accompanying drawings.

[0032] figure 2 is a block diagram showing the configuration of the image scanning apparatus according to the present invention.

[0033] refer to figure 2 , the image scanning device (10) includes an input device (100), an A / D converter (110), a control device (120), a memory device (130) and an image synthesis device (140).

[0034] The input device (100) includes an image scanning section for performing a function of scanning an image (200) and absolute coordinates for detecting a position of a surface by utilizing unevenness or the like of a surface (not shown) having an image The position detection part of the value or relative coordinate value.

[0035] The image scanning part of the input device (100) is implemented as an image input device such as a CCD or a CIS, which detects light emitted from a light source and then reflected by...

Abstract

A surface coordinate image mapping technology (SCIMT) synthesizing and restoring images by using the coordinate value of the surface of the scanned object and matching image data thereto is disclosed. The coordinate value of the position for a surface having the image data of the scanned object is determined. The image data is matched with the coordinate value of the position for the determined surface and collected. The entire image is synthesized by using the coordinate value matched with the collected image data. By performing image scanning following the above process, the entire image can be restored regardless of the size of the image data of the scanned object even when a small sized scanning device is used. Also, regardless of the scanning direction, the entire image can be easily synthesized and restored freely by a single continuous scan.

Description

technical field [0001] The present invention relates to a method for scanning an image by using coordinate values ​​of a surface to be scanned and a device using the method, more particularly, to a method for scanning the scanned surface by determining the absolute coordinate value or relative coordinate value of the surface having a document or image A method of matching image data with coordinate values ​​and restoring the image data by synthesizing the image data matched with the coordinate values ​​using the determined coordinate values ​​in the X and Y axis directions. [0002] In other words, the present invention relates to a method of reading a surface coordinate value by using a small portable image scanning device, matching scanned image data with the coordinate value, and synthesizing and / or restoring the scanned image of the image according to the coordinate value and using The device of this method, which is capable of scanning images larger than the scanner regar...
