Description
[technical field]
The present invention relates to a kind of scanning means and scan method, particularly relate to and a kind ofly can proofread and correct scanned crooked scanning means and scan method.
[background technology]
Scanner can be widely used in the device of archives electronization in office even the family as a kind of.Fig. 1 illustrated prior art a kind of scanner face generalized section.Scanner among Fig. 1 comprises pedestal 10, and pedestal 10 has accommodation space 11, and image obtains module 12 and is arranged in the accommodation space 11; Transparent panel 15 covers accommodation space 11; In when scanning, scanned 90 are placed on the transparent panel 15, and it is scanned 90 that cover plate 21 is pushed down, and image obtains module 12 and moves in the direction of arrow E from initial position, can scan whole scanned 90.Cover plate 21 connects pedestal 10 by bindiny mechanism 22.One end of bindiny mechanism 22 is positioned on the pedestal 10, and the other end articulates cover plate 21.Taking off scanned 90 o'clock, and earlier cover plate 21 to be raised.When large volume document was scanned, scanner shown in Figure 1 was scanned owing to will frequently picking and placeing, so efficient is lower.Therefore, the common scanner that has full-automatic inlet device that uses as shown in Figure 2.Fig. 2 illustrated prior art another kind of scanner face generalized section, it is replaced by full-automatic inlet device with the cover plate among Fig. 1 21.Full-automatic inlet device among Fig. 2 comprises being scanned between part placing plate 33, the first guide plate 31, the second guide plates, 32, the first guide plates 31 and second guide plate 32 and forms scanned transfer path.First guide plate has opening 315 in the zone that the described image of correspondence obtains the initial position of module 12, and image obtains module 12 and scans the scanned of process transfer paths by opening 315.The surface of second guide plate, 32 corresponding described openings 315 is a background block 325, and background block 325 is generally white, in order to avoid influence is to scanned scanning effect.When the promptly satisfied scanning of the skin-material of second guide plate 32 itself requires, needn't make background block 325 especially.When work, be placed on scanned (for example contribution) that be scanned on the part placing plate 33 and entering the scanned transfer path that forms between first guide plate 31 and second guide plate 32 under the driving of mechanisms such as driving wheel page by page, and be scanned at opening 315 places.Fig. 3 illustrates the local elevational schematic view of full-automatic inlet device among Fig. 2, and image obtains module 12 corresponding to scanning area 120.Fig. 4 illustrates the schematic diagram of one page contribution 91 through Fig. 3 split shed 315.At this moment, contribution 91 moves in the direction of arrow F, and image obtains module 12 and continues to obtain image, finally forms the complete image of contribution 91.With common rectangle contribution 91 is example, a problem that often occurs in this process is, the dual-side 911,912 and the arrow F direction of contribution 91 not parallel (being the head and the tail both sides 913,914 and the arrow F direction out of plumb of contribution 91), this image that can cause scanning acquisition is crooked.This problem generally is that the alignment error by full-automatic inlet device itself design or itself and pedestal 10 causes, and is difficult to eliminate fully from mechanism.
No. 6360026 (US6360026) patent descriptions of the U.S. a kind of solution of the above problems, can it be applied on the scanner shown in Figure 3 after transforming, specifically can be with reference to figure 5 and Fig. 6.Fig. 5 has illustrated a kind of local elevational schematic view of full-automatic inlet device of the scanner with contribution skew corrected function; Fig. 6 has illustrated the schematic diagram of one page contribution 91 through Fig. 5 split shed 315.As shown in Figure 5, corresponding scanning area 120 is provided with sign block 326 on background block 325, when contribution 91 along the direction of arrow H during through opening 315, image obtains in the image that module 12 obtains can comprise the image information of contribution 91 and the image information of sign block 326 simultaneously.By to information processing, can identify the border of the image of the image of contribution 91 and sign block 326, thereby calculate the skew angle of contribution 91, and then according to the image of the contribution 91 of this angle modification output.But there is shortcoming in this technology, the one, and when the contribution that scanning approaches, the pattern of sign block and color can embody in the image that obtains to some extent, influence image quality; The 2nd, owing to will carry out a large amount of information processings, cause sweep speed slack-off.
