Abstract
The utility model relates to an image scanning device with a multi-channel optical filtering module. The image scanning device can collect the images of a scanned file with various optical effects at one time. Through collecting the images with various optical filtering effects, the image scanning device can offer help for the automatic processing process of the subsequent images, including background interference with various colors on a filtering manuscript, enhance partial color signals, and particularly extract anti-counterfeit information on the manuscript, thereby greatly enhancing the adaptability of the scanning device.
Description
Technical field
The utility model relates to a kind of image scanning device, can disposable collection be scanned the image of the multiple different optical effect of document.
Background technology
Scanning of image equipment such as existing scanner, cleaning-sorting machine, its scanning theory is identical, " line " scanning of promptly original copy being carried out is called as " main scanning ", and photo-electric conversion element such as linear CCD are called " subscan " with respect to the parallel mobile scanning input of original copy.The implementation of " subscan " comprises parallel moving photoconductor conversion element and two kinds of parallel mobile original copys.Image how to gather the special optical requirement then is a new problem, and some products are realized by pasting filter membrane or installing the mode of filtering eyeglass additional, can only obtain a subpicture but the shortcoming of such method maximum is a single pass, and certain limitation is arranged.
Summary of the invention
The purpose of this utility model then is at above-mentioned the deficiencies in the prior art, for satisfying diversified image acquisition demand, designed a kind of multichannel optical filtering formula module, can in the process of single pass, realize gatherer process the image of a plurality of different optical filter effects.
The purpose of this utility model can realize by following measure:
A kind of image scanning device that has multichannel optics filtering module, promptly a multichannel optics filtering module 1 is installed at photo-electric conversion element 3 front ends of image scanning device, include a plurality of optical path independently mutually in the multichannel optics filtering module 1, the colour filter 2 of different optical effect is installed at the front end of each optical path.By behind the multichannel optics filtering module 1, form a plurality of scan channels like this, can in the process of single pass, obtain the image of a plurality of different optical filter effects after handling through photo-electric conversion element 3 with different optical filter effect.
The beneficial effects of the utility model are:
By gathering the image of different optical filter effect, can offer help for follow-up visual automation processing procedure, comprise the versicolor ambient interferences of filtering on the original copy, strengthen the part color signal even can extract anti-counterfeiting information on the original copy, strengthened the adaptability of scanning device greatly.
Description of drawings
Fig. 1 is the sectional view of multichannel optics filtering module 1 of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
Multichannel optics filtering module 1 of the present utility model can be the combination of a plurality of rectangular channels as shown in the figure, front and back printing opacity, sealing all around.At the passage front end colour filter 2 of different-effect can be installed, photo-electric conversion element 3 be installed to obtain the image of different optical filter effect at the end of passage.
Embodiment 1: the end of each passage of multichannel optics filtering module 1 is linear photo-electric conversion element of correspondence separately, and each linear photo-electric conversion element can work independently, and obtains the image of different optical filter effect in the process of single pass respectively.
Embodiment 2: the end of all passages of multichannel optics filtering module 1 can a shared matrix photo-electric conversion element, and the data that the matrix photo-electric conversion element is obtained can be by obtaining the image of different optical filter effect after the processing that splits combination.
Embodiment 3: during the information such as infrared or Ultraluminescence security devices that obtain to have on the original copy as need, operable corresponding colour filter can extract in conjunction with corresponding light source.
Claims (2)
1, a kind of image scanning device that has multichannel optics filtering module, it is characterized in that photo-electric conversion element (3) front end installation multichannel optics filtering module (1) at image scanning device, multichannel optics filtering module (1) includes a plurality of optical path independently mutually, front and back printing opacity, sealing all around, the front end of each optical path is equipped with the colour filter (2) of different optical effect.
2, the image scanning device that has multichannel optics filtering module according to claim 1, it is characterized in that can be separately corresponding linear photo-electric conversion element of end of each passage of described multichannel optics filtering module (1), all passages also can a shared matrix photo-electric conversion element.
