Abstract
The present invention relates to a scanning equipment, including a shell body, a scanning module, a file cover and a file-bearing plate, in which the shell body has a side edge portion, the side edge portion and the file cover are formed into an identical gradation-progressive colour area by means of plastic injection-moulding mode, and the colour area can be used as a mode for judging the file range. The method for judging file range includes the following steps: scanning, picking data, comparing different place and identical place of data, summing all the places with different data and combining them together, it is the range of the file.
Description
Technical field
The invention relates to a kind of scanner, and particularly relevant for a kind of side portion that can utilize housing compare with the identical gradually layer of file lid tool color region, the mode of steps such as judgement judges the scanner of file extent.
Background technology
Along with the progress and the fast development of electronics technology, computer has become one of outfit indispensable in the modern society, and multiple high performance computing system also arises at the historic moment thereupon, and existing increasing electronic product is used in daily life continually.Except utilizing the direct pick-up image pattern of digital camera, the image input operation of other relevant document or picture, all need to capture the analog image of literal or pattern by optical scanner, and to the digital signal output of converting, help the user on computer or other electronic product, carry out the actions such as demonstration, identification, editor, storage and output of image archives.
In the scanning process of scanner, with the file that will scan, be positioned on the file loading plate, then cover the file lid on the scanner, come scanned file flattening by sponge (sponge) in the traditional file lid and film (sheet), and can avoid veiling glare to inject and have influence on scanning quality.The film of its white that all file is covered captures and judges the image of file as being a kind of pattern in addition.
Among scanning system, decision influences one of key element of scanning quality, promptly be size and the scope whether scanning system can accurately judge file to be scanned, so that this scanning document image sensing component is brought into play best image pixel sensing effect in the optimal operations scope.Yet, generally speaking, scanner is treated as a kind of background color by the film in the file lid, capture the image of scanning document, because only use the background for the treatment of as scanning document with a kind of background color of colour system, when the background color of the background color of scanning document and film is close, it is the background color of scanning document that scanner can be thought the background color of film by mistake, and make computer treat the desire scanning area misjudgment of scanning document, can make the size and the scope of file to be scanned very accurately to be judged like this, thereby have influence on whole scanning quality by computer.
Please refer to Fig. 1, it is the schematic diagram of known scanner.One scan instrument 100 is applicable to scanning one file (not illustrating), and file can be placed on the file loading plate 106.One scan module 109 is configured in the file loading plate 106 times, and scan module 109 can move left and right come scanning document.One file lid 102 has a sponge 104, a film 105 and a cover plate 101, and sponge 104 and film 105 are disposed under the cover plate 101.File is positioned on the file loading plate 106, down pressing is smooth in file with file lid 102 then, by the effect of sponge 104 with film 105, this file is flattened, follow the scan module 109 in housing 108, the action that this file is swept in advance earlier, and the function of frame choosing can use the color of film 105 as background color when carrying out automatically, because only work as background with same colour system color, when the color of file of scanning is close with background color, one computer (not illustrating) can be thought the background color of film 105 by mistake to be the color of file, and cause the situation of document image erroneous judgement to take place, can't very accurately judge the size and the scope of file like this, thereby have influence on the file scanning quality, cause the low of document quality.In addition, the sponge 104 and the film 105 of the file of known scanner 100 lid 102 its objective is in order to flatten file and to avoid veiling glare to inject, sponge 104 and film 105 be not with file lid 102 be one-body molded, combine.After sponge 104 and film 105 use for a long time in addition, the situation that has color change takes place, and might influence the scanning quality of file, the sponge 104 and the film 105 that therefore must consideration more renew, so except problem consuming time, and certainly will also can increase the more expense of conversion materials.
Summary of the invention
One of purpose of the present invention is exactly at the scanner that provides a kind of file extent to judge, by the side portion of housing and the gradually layer color region of file lid, compares, step such as judgement, and the method for acquisition file extent.
For reaching above and other objects of the present invention, the method that a kind of file extent is judged is proposed, comprise the following steps: at least
Step 1: cover the work that file lid scan module begins to sweep in advance.
Step 2: scan module can capture the image of a sub-scanning area on the same horizontal reference simultaneously, scan module can obtain sub-side portion data and subfile loading plate data, then scan module can arrive and obtain another sub-side portion data and another subfile loading plate data on another horizontal reference simultaneously by that analogy, finishes up to all data acquisitions.
Step 3: the subfile loading plate data that captured on sub-side portion data that sub-scanning area captured and the same horizontal reference are compared, judge sub-side portion data and the identical place of subfile loading plate data, be defined as a sub-identical data, and judge sub-side portion data and subfile loading plate data place inequality, be defined as a sub-different pieces of information and then continue another sub-side portion data of comparison and another subfile loading plate data on same horizontal reference, and also judge another sub-identical data and another sub-different pieces of information, by that analogy, finish up to all data comparisons.
Step 4: all sub-different pieces of informations are combined, and obtain a file reference data,
And the scope of file reference data is the scope of this document.
In sum, the present invention can utilize the gradually layer color region of side portion and the gradually layer color region of file lid, has identical gradually layer color on same horizontal reference, and judges the size and the scope of file by acquisition, than reciprocity step.
One of advantage of the present invention is to reduce the erroneous judgement of automatic frame choosing (auto-crop).
Two of advantage of the present invention is that file lid can be that the mode of plastics ejection formation is made, and therefore can save the sponge and the soft board of scanner file lid.
