Abstract
The multiple background device for scanning instrument and correcting device in the same operation principle includes rotation shaft, axial low light reflectivity area and axial high light reflectivity area. When the rotation shaft is in different position to make different reflecting area corresponding to the optical module, different scanned background color may be provided. When the rotation shaft rotates relatively to the optical module and the optical module rotates, several scanning lines may be obtained in the surface of the rotation shaft for correcting chromaticity.
Description
Technical field
The invention relates to a kind of background transitions and chroma correction means of scanner.This device has background colors different more than two kinds, can switch the optical module of the corresponding scanner of background color, and reaches the effect of conversion scanning background.Use same principle, also can provide the sweep trace of different colourities, and reach the effect of adjusting optical module colourity.
Background technology
General flat-bed scanner is equipped with movably optical module.When scanning, this optical module straight line moves, and can obtain the sweep trace of many reflections from file to be scanned when moving, and light sensing apparatus (optical sensor) just produces scan-image according to resulting scanning information.
When paper surface to be scanned has perforation or document edge to be scanned tear trace is arranged, scan-image can stain occur in the position of correspondence perforation, or produces shadow at image edge.It is because the bottom surface of scanner lid is a black background.Solve the above-mentioned method that stain or shadow occur and can make the bottom surface of lid into white background.
Except that the method for above-mentioned change lid bottom surface color, another kind of method is the background that forms two kinds of different colours in the bottom surface of the lid of this scanner, particularly comprises a black background and a white background.Before the use, drive this optical module according to operating position and move to selected background below, when file to be scanned to be moved passes through this optical module, just can carry out pick-up image information.Because this kind mode must be at optical module for movably just can carry out the conversion of background under the situation, so this design is only applicable to have the falt bed scanner of chart drive assembly.For example US PAT 6,166, and 394 just disclose the designed scanister of above-mentioned technology.The disclosed method of this patent case must be adjusted the position of optical module with background position difference in addition, so the positioning design more complicated of optical module.
For falt bed scanner, it, just can combine so that double-sided scanning function to be provided with the sheet fed scanner with fixed ray machine this scanner structure appropriateness change, adjustment except scanning separately the use.But because the optical module of two scanners all is designed to stationary state, so this sheet fed scanner if will by by the mobile optical module to reach the purpose of changing background color, will change angle, the distance of the corresponding file to be scanned of optical module, make the light path of image information change, resulting scan-image like this just can produce error.In other words, if will keep preferable image quality and can change background, best mode is optical module to be fixed and background is convertible, and so the light path of image information just can not be affected.
On the other hand, the optical module of sheet fed scanner must be proofreaied and correct colourity earlier before carrying out scanning.Fixed optical module can't be by obtaining the multi-strip scanning line as correction parameter, so the correction fiduciary level is not high by move mode.And according to US PAT 6,323,933 patent cases, the fixed optical module above the scanner can by by below the moving of optical module, and the correcting sheet that is positioned at certainly on the optical module of below is obtained the foundation of multi-strip scanning line as chromaticity correction.But above-mentioned patent case still existence meeting is different apart from the different optical path lengths that cause of distance of top optical module with actual file apart from the distance of top optical module because of the below optical module, produces the coarse shortcoming of chromaticity correction result.
Summary of the invention
An object of the present invention is to provide a kind of many Background apparatus of scanner, it has the function of conversion scanning background color, in order to eliminating the stain that perforation caused because of file to be scanned, or because of the shadow that the edge causes of tearing of scanning object.
Second purpose of the present invention provides a kind of chroma correction means of scanner, and it is used for scanner before carrying out scanning, by obtaining the multi-strip scanning line on these many Background apparatus, as the chromaticity correction foundation of optical module.
According to above-mentioned purpose, effect, the present invention disposes scanning window and the optical module of rotating shaft with corresponding scanner in scanner, and is formed with low light line reflection portion and high light line reflecting part in this rotating shaft.In the time of need making background transitions, this rotating shaft is rotated with the corresponding scanning window in different light reflectance positions; And need make the colourity timing, this rotating shaft only need comprise a kind of light reflectance portion and get final product; Then this rotating shaft rotation one circle makes this optical module can obtain the multi-strip scanning line for chromaticity correction.
