Description
Technical field
The present invention relates to a kind of sheet folder and scanning bearing calibration of sub-scanning, particularly a kind of scanning bearing calibration that realizes continuous dynamic calibration to the sheet clamping structure.
Background technology
When using flat or portable scanner, before scanning, generally a process of doing correction can be arranged all, this aligning step comprises three aspects: the time for exposure proofreaies and correct, deceives and proofread and correct and white the correction.So-called black the correction is meant the standard black signal of the black correction data of utilization as the scanning imagery element; So-called white correction is meant and utilizes the reference white picture signal of white correction data as the scanning imagery element.
In the prior art, trimming process is separated with formal scanning process, proofreaies and correct afterwards earlier and scans, and the process of correction normally scans specific correction masterplate.The general flow of proofreading and correct comprises: the motion scan module perhaps is provided with scanning module and initially is parked in correction masterplate position to specific correction masterplate position; Open scanning light source, the correction exposure time; Time for exposure is scanned this correction masterplate after proofreading and correct and accomplishing when scanning light source is opened, generate white correction data, and this correction masterplate of scanning when scanning light source is closed generates black correction data; After all proofreading and correct completion, scanning module gets into formal scanning process.
The shortcoming of this scanning bearing calibration is, proofreaies and correct with formal scanning process and independently accomplishes, and causes scanning process discontinuous, not intelligent, and the user uses inconvenience.
Summary of the invention
To the problems referred to above, the present invention provides a kind of sheet folder of sub-scanning and uses the scanning bearing calibration of this sheet folder, to reach correction is placed on the purpose of accomplishing and do not influence quality of scanning in the single pass process.
The sheet folder of sub-scanning provided by the invention comprises the body in order to the clamping scanning object, and this body places in the scanning means along the plane of scanning motion, and this scanning direction, body upper edge comprises correction window and scanning window successively.Correction window is used for the auxiliary white correction data that generates, and this correction window is first width along the Breadth Maximum of first direction, and this first direction is perpendicular to this scanning direction, and this first direction and this scanning direction all are parallel to this plane of scanning motion.The scanning window is used for this scanning object of sub-scanning, and this this first direction of scanning windowsill has second width, and this second width is smaller or equal to this first width.
According to of the present invention folder, correction window has at interval with scanning windowsill scanning direction.
Based on of the present invention folder, this sheet folder comprises also that along the scanning direction guide surface, this guide surface are arranged at an end of body, and correction window is arranged between this guide surface and the scanning window.
Scanning bearing calibration provided by the invention may further comprise the steps.(1) aforesaid is inserted and put into scanning means.(2) search the position of this correction window along this scanning direction.(3) confirm the position of this correction window after, scan this correction window and generate white correction data.(4) scan the interior scanning object of this scanning window, obtain scan-image, and utilize this white correction data that this scan-image is proofreaied and correct.
According to scanning bearing calibration of the present invention, step (1) also comprises before: open this scanning means and carry out exposure correction, obtain first time for exposure and black correction data; Also comprise afterwards in step (1): use this first time for exposure to begin scanning along this scanning direction from an end of this sheet folder.
Further, in step (4), also comprise: use the scanning object in this scanning window of this scanning first time for exposure, and utilize respectively and should deceive correction data and reach this white correction data this scan-image is proofreaied and correct.
According to scanning bearing calibration of the present invention, between step (1) and step (2), also comprise: close scanning light source, an end that presss from both sides from this sheet uses preset time for exposure to begin scanning along this scanning direction, generate and deceive correction data; Open this scanning light source then, and continue scanning.
Further, in step (3), also comprise: after confirming the position of this correction window, this scanning means is carried out exposure correction, obtained for first time for exposure; After accomplishing exposure correction, scan this correction window and generate this white correction data.
Further, in step (4), also comprise: use the scanning object in this scanning window of this scanning first time for exposure, and utilize respectively and should deceive correction data and reach this white correction data this scan-image is proofreaied and correct.
According to scanning bearing calibration of the present invention, in step (2), utilize the different positions of confirming this correction window of this correction window with the GTG signal of this body.
Through the present invention, can correction be placed in the normal scanning process, do not influence the quality of scan-image simultaneously, also can reduce whole sweep time, and more meet user's use habit.
