The present invention relates to a method for achieving boundary localization in a scanning apparatus, as well as to a scanning apparatus, which is capable of achieving intelligent judgement on boundary localization of the scanned file by means of this method, through an effective combination of optical, electronical and mechanical techniques.
This application claims priority from China Patent Application No. 200910238868.4, filed on 30 Dec. 2009, the contents of which are hereby incorporated by reference in their entirety for all purposes.
With the scanning apparatus of conventional art, upon scanning an item of an undefined format, unwanted marginal corners often appear although files or pictures to be scanned is enabled to be scanned and stored. Thus, the scanned files obtained usually need to be re-processed by other softwares.
The scanning apparatus is generally classified into two types, the first is the paper feeding type, the other is the backboard type. The backboard type generally means that the entire plane surface that can be sensed by the whole of the sensor module of the scanning apparatus is scanned, or the file is scanned while being placed at the position of a defined specification, and the processing method for the item to be scanned having a special specification or shape is utterly absent. Then, as to the paper feeding type scanning apparatus, an activation lever is generally provided at the file inlet, thus the width of the file may be determined; then whether or not the scanning of the file is completed is judged via the passing switch provided at the paper inlet. Thus the operation has to be carried out manually, and as to the item to be scanned having a special shape, the boundary localization is still unsatisfying.
One of the purposes of the present invention, a scanning apparatus capable of achieving boundary localization, is to solve the problems in the conventional art.
The present invention may be realized with the following technical solution:
A method for achieving boundary localization during scanning, said method comprises: a regular ribbon, a sensor module capable of detecting the ribbon, and the file to be scanned is placed between the ribbon and the sensor module; said sensor module first scans the ribbon information and stores it in the storage module of the scanning apparatus; said file to be scanned is placed between the sensor module and the ribbon, the sensor is capable of deriving the boundary position of the file to be scanned by means of contrast measurement through the measured ribbon portion covered by the file to be scanned.
Wherein, the ribbon is composed by regular color codes. The color code may consist of graphs, patterns or color blocks successively arranged that have color differences.
A paper feeding type scanning apparatus capable of achieving the method of boundary localization during scanning, said scanning apparatus comprises: a scanning apparatus processor and a scanning apparatus scanning terminal, the scanning terminal is provided with a CIS module, and is further provided with a ribbon that is correspondingly placed between the CIS module and the file to be scanned; said ribbon is a strip-like ribbon with alternating colors and is provided at the paper inlet of the scanning terminal of the scanner; the ribbon is composed by transversely connecting color grids having a common width, and the paper to be scanned is provided between the ribbon and the CIS module; said CIS module is connected with the storage elements of the memory of the scanning apparatus. The ribbon is composed by the color grids with at least two different colors arranging in the length direction of the strip of the ribbon.
Wherein, a preferable ribbon is a ribbon with three alternating colors, that is, the red, green and blue colors.
A backboard type scanning apparatus capable of achieving the method of boundary localization during scanning, the scanning terminal of said scanning apparatus comprises a scanning plane provided with a sensor module and an upper cover opposite to the scanning plane for fixing the item to be scanned, said upper cover is provided on the surface opposite to the sensor module with a ribbon; said ribbon is covering on the whole of the upper cover; the color codes on the ribbon is composed by color blocks with different colors or patterns regularly arranged; said sensor module is connected with the storage elements of the memory of the scanning apparatus.
Wherein, a preferable ribbon may be a ribbon with three alternating colors, that is, the red, green and blue colors, or the ribbon is a ribbon that is composed by squares, triangles and circles that are regularly arranged.
With the scanning apparatus capable of achieving boundary localization provided by the present invention, while it is ensured that the operation is convenient, and the structure is simple, it is enabled to achieve a precise boundary localization on the item to be scanned, thus the post-processing of the scanned file by the user is facilitated.
Hereinafter, the present invention is further explained referring to
As shown in
Referring to what is shown in
Upon completion of the scanning, the paper 103 passes automatically, thus the ribbon 101 is re-exposed to be under the CIS module 102 of the scanning terminal. At this time, by the same principle as above, the scanning apparatus will immediately interrupt the scanning of the file, thus the realization of the file boundary localization is attained.
With reference to
During actual operation, that is, upon shipment or calibration, the ribbon 205 on the backboard may be fully scanned by the scanner, and the content thus obtained will be stored in the storage of the scanner perfectly.
When the scanner is to be used for scanning a file, the upper cover 201 needs to be opened first, then the file 206 is placed on the glass plate 204, and the upper cover 201 is closed. At this time, since the file is located between the CIS module 203 and the upper cover 201, the ribbon 205 may be covered by the file 206, and the CIS module 203 is incapable of scanning the content of the portion of the ribbon 205 that is being covered. As shown in
The above is a detailed introduction of the scanner and the particular operational manner thereof provided by the present invention. The specific structure and the implementation method thereof of the present invention is set forth with particular examples in the present context and the above embodiments are merely intended to help understand the core idea of the present invention. Meanwhile, as to those with ordinary skills in the art, according to the idea of the present invention, modifications may be made to the specific manner of implementation and the scope of application. To sum up, the content of the present description is not to be considered as limiting the present invention thereto.
