In addition, about camera 16 or scanner 17, can be configured to be connected multiple stage with PC11, also be configured to only there is any one party.Camera 16 such as takes various subject relative to worktable 18 or lighting source 16a with arbitrary Distance geometry angle etc., and camera 16, freely to arrange and the mode of movement, is installed via scaffold 18a.In scanner 17, platform or the platform installed for ADF or mechanism can also be read at the same position not shown medium installed for carrying out reading.

Image testing device 10 is such as to as the data represented as the benchmark image checking benchmark, the 1st view data be made and the 2nd view data be made as the data represented as the check image of check object compare, discrepancy (comprising dust, stains etc.) between automatic extraction the 1st view data and the 2nd view data, wherein, this benchmark image is as inspection benchmark, this check image as check object.1st view data comprises the two-value or many-valued printing view data (printing numerical data) that are exported by RIP (RasterImageProcessor: raster image processor) device.1st view data and the 2nd view data comprise: the printing images during the color printed out adjusts or the printing images in formally printing; And before printing, the view data that is made by DTP software or printing view data.

Benchmark image refers in the reference media of the complete paper in the school such as, after the printing as printing firm and client has corrected in various medium and prints the image that (printing) goes out or the image be made up of printing view data.Check image refers to the image be such as made up of the view data before printing the inspection medium of printed article etc. or printing view data or the image printed out in inspection medium.In these benchmark images and check image, comprise all images that the colour chart of word, numeral, figure, symbol, decorative pattern, photo, code etc. and IT8 or the color control bar of color adjustment etc. can be visual.But, the image be made up of the data of not visible eletric watermark etc. is sometimes also comprised.

As reference media and inspection medium, except the complete paper in above-mentioned school and printed article, the plane object such as formed by various material in addition or slightly concavo-convex paper, polyethylene film, cellophane, PET (polyethylene terephthalate), PP (polypropylene screen) subsides, cloth, metal, evaporation paper, resin, timber, stone material etc.In addition, in color material, have in color of light, luminophor etc., there is the dyestuff such as the pigment such as oiliness ink/coating, aqueous ink/dye color liquid or comprise the luminous object of color monitor of liquid crystal, EL or laser etc.

In addition, in the shape of other medium, have and can carry out printing or the various bottles, tank, PET bottle, kettle/plate/household electrical appliances etc. of processing of coating etc., in addition, also have the tablet of medicine, the panel component of equipment or electron plate etc. directly to print or carry out the object installing processing such as welding, medium can be the object in the drafting be made by various material or the stereoscopic article pasted with the product of the images such as color bar/decorative pattern/illustration/photo/drawing/word etc.Below, show as the example of applying in a flexible way in common printing process.

Functionally, image testing device 10 is formed as shown in Figure 2.That is, as shown in Figure 2, image testing device 10 has the functional structure of storage part 2, image processing part 3, Differential Detection portion 4, image production part 5, image checking portion 6 and check result handling part 7.Storage part 2 temporarily or for good and all Memory Reference image and check image.The function of the audit by comparison software of image testing device 10 has inspection area set-up function, threshold value set-up function, image registration functionality, check result Image Saving function and Inspection information list function.

Image processing part 3 using stored benchmark image at least partially with check image at least partially as the 1st view data and the 2nd view data, pixel scale carries out correspondence, carries out the picture registration process overlapped.Differential Detection portion 4, according to arbitrary threshold value, compares the 1st view data after picture registration and the 2nd view data, detects the difference between these view data.In addition, picture registration and images match are synonyms.In addition, in threshold value, exist " condition threshold " that carry out according to single threshold value " the simple threshold value " evaluated and carry out for the combination condition (such as, be different threshold values etc. for the upper limit, lower limit, each color) according to multiple threshold value evaluating.Below, when being merely denoted as " threshold value ", comprise its both sides.In addition, in " simple threshold value ", there is one " single threshold value " and plural " multiple thresholds ".In addition, in " condition threshold ", exist one " condition threshold " and plural " multiple condition threshold value ".In addition, for the region of not carrying out checking, can not threshold value be set, or make threshold value be 0.

In image processing part 3, when obtaining view data from camera 16, such as, when comparing inspection with printing numerical data, sometimes because the aberration etc. of lens produces the distortion of input picture, make in the picture registration of benchmark image and check image, the position of image grades in top and the bottom, left and right to produce and skew occurs and does not aim at.In addition, equally, in the view data obtained from scanner 17, due to the aberration etc. of lens or the inequality of scanning, even if carry out picture registration to benchmark image and check image, the situation that the position that also there is image also occurs to offset and do not aim at.

In this case, if error is less, the image that then can compare inspection to input carries out Factorization algorithm and carries out picture registration, or Scalable or rotation etc. (compound ground) are carried out to image and carries out picture registration, but, when the position of the size of image or image section is different very brokenly, image can not overlap sometimes.

Therefore, by indicating, printed article is estimated, and the position about the linea angulata (corpmark) up and down of adjustment or 4 ~ 15 places of central point overlaps, or by selecting the L word of bight linea angulata (slitter marks) or the cross section of cross part of corner, carry out the trapezoidal Image Adjusting process waiting distortion correction, easily can carry out picture registration.Or, input picture can be divided into rectangular or freely to Image Segmentation Using, by being divided into rectangular unit to carry out picture registration, in addition, also automatically can select the unique point of each image, carrying out the process of scalloping correction.In addition, about scanner image, also as described above, easily there is reading speed uneven, therefore need the correction carrying out reading images.But, when the departure of image is more than certain value, the mechanism of not carrying out picture registration also can be taked.

Image production part 5, in order to compare each other the multiple discrepancy display images producing difference further according to multiple threshold value (TH1 ~ THn), generates the discrepancy display view data of each threshold value.Image checking portion 6 uses the discrepancy of each threshold value generated display view data to carry out image inspection process.In addition, the Image Adjusting accompanied with picture registration process in image processing part 3 such as also comprises: the overstriking of line or image/subtract thin process; The various image correction process of gray correction; And the color of image correction process etc. such as the color conversion employing description document.

Thus, the view data of having carried out above-mentioned image correction process directly can carry out the inspection of word and tone etc. accurately in image checking portion 6.Check result handling part 7 generates the check result report following content gathered: the discrepancy display image of the discrepancy display view data generated by image production part 5; Based on the image of check result discrepancy display view data, wherein, in described check result discrepancy display view data, show at the difference image of the discrepancy display area corresponding with the threshold value of the optimum selected in the image inspection process at image checking portion 6 or in difference image, with the addition of indicia framing; And the number positional etc. of discrepancy.

In addition, so-called discrepancy refers to following situation.That is, discrepancy refers to there are the different whole circumstances in the images such as word/photo/figure, and it comprises: the misprints such as word drop/dust/stains; The deviation of the shape of line slightly, word or image in image that produce because of the difference of overlap bad or RIP process, that export; And the image error of noise, word, pattern correction position etc.Below, they are called discrepancy without exception.

When carrying out picture registration, pixel scale carries out correspondence, such as, the least unit being composing images with the point in image, adopts the dot information of simple physics.In addition, 1 pixel (pixel) in image is usually used as the least unit of composing images, and use as the synonym of " point ", be set to: there is the least unit of colouring information (tone or gray scale etc.) or minimum key element by during PC11 process image herein.Therefore, when monochrome, 1 point is 1 pixel, and when colour, RGB is 1 pixel, and CMYK is 1 pixel, and XYZ is 1 pixel, or L*a*b* is 1 pixel.In addition, due to the rank below pixel picture registration will be carried out, therefore, in 1 pixel scale, by carrying out based on deep or light dithering process, the image display of position alignment can be carried out exactly, until the error range below 1 pixel scale.

Colouring information can be such as CIELAB (L*a*b*) value, CIEXYZ value, colour atla displayed value, dichroic reflection waveform, spectral image, rgb value, CMYK value, concentration value, reflectance-transmittance rate, infrared wavelength, ultraviolet wavelength or the x-ray wavelength etc. that are obtained by color filter.In addition, in L*a*b*b color specification system, L* can be used to represent lightness, and form and aspect and chroma are as tone to use a*b* to represent.In addition, respectively, a* and b* represents the direction of color, and+a* represents red direction, and-a* represents green direction, and+b* represents yellow direction, and-b* represents the respective color direction in blue direction.In L*a*b* color specification system, along with the numerical value of these each parameters increases, color turns bright-coloured.

In addition, the aberration between benchmark image and check image can calculate by comparing these quantitative values above-mentioned, and is represented by Δ E or CIEDE2000 etc. of CIE1976.In addition, as the view data of printing machine or printing, by being represented by the site % value of each version of CMYK, thus, can utilize as the feedback information adjusted the color of printing machine, or for the color correct etc. of data of making a plate in design department, Yin Qian department or printing workshop.

Check result image is stored in HDD (hard disk drive) 29.In check result image, two images after benchmark image overlaps from check image and the difference image that generates respectively according to multiple different threshold value link as the respective Rotating fields of two images, and carry out data preservation.In addition, or benchmark image and check image also can be made to coincide with one another and synthesize an image, the difference image generated according to multiple different threshold value links as the Rotating fields of an image, and carries out data preservation.In addition, when specifying identification colors to the difference image generated according to each threshold value, the information of identification colors is recorded in the head of check result image.

About check result image, even if in the PC without audit by comparison software, also can read by downloading the simple and easy display view software performing exploitation in addition.In addition, check result image construction is the discrepancy that can be caused by threshold value by above-mentioned view software certification.Thereby, it is possible to according to check result image, show benchmark image and check image in the mode of stagger (あ お り), show benchmark image and check image in overlapping manner, or show two on all four positions of image in half mode adjusted.In addition, the difference image generated according to specific threshold value can be selected from multiple difference image, color display is carried out to discrepancy, alternately shows with different identification colors respectively according to multiple difference images that different threshold values generates, or alternately show after changing identification colors.In addition, the threshold value of mark display can be set, and then, by changing threshold value, making it possible to the size (pixel count) according to Threshold selection differential pixel, carrying out mark display.

Next, reference media 30A is taken off from worktable 18, in the same manner as in time loading reference media 30A, the position being placed on the regulation on worktable 18 as the inspection medium 30B of the complete paper in school or printed article etc. of the check image of check object will be printed with, take check image by camera 16 and lighting source 16a, the check image (the 2nd view data 32) obtained according to this shooting image is stored in video memory 28.

Herein, in the inspection example of the simple threshold value shown in Fig. 4, compared with the image of the 1st view data 31, in the image of the 2nd view data 32, comprise several discrepancy (mistake) E as described above.In addition, the 1st view data 31 and the 2nd view data 32 can be obtained by 1 Camiera input mode, and the operation associated codes of these two view data 31,32 as 1 paired file and Inspection is got up to be kept in the working folder of HDD29 etc.Carry out equally, a paired file under preserving can be used, carry out the continuous self-verifying of simple threshold value or condition threshold.

As mentioned above, by being used as image fetching unit or image acquisition unit and a PC11 and camera 16 played a role, first obtaining benchmark image and check image, generating and storing the 1st view data 31 and the 2nd view data 32.The mode obtaining taking image by using such a camera 16 is respectively called single Camiera input mode, it is further preferred that when taking, read benchmark image and check image with roughly the same size and resolution.

In addition, as shown in Figure 5, about these the 1st view data 31 and the 2nd view data 32, can be generated by following two Camiera input mode: in image testing device 10, equip two cameras 16 and worktable 18, under the lighting source 16a (not shown) of the same terms, a camera 16 is utilized to take the benchmark image of reference media 30A, utilize another camera 16 to take the check image checking medium 30B simultaneously, utilize PC11 to obtain two shooting images, and the ground that overlaps show.In this pair of Camiera input mode, the display frame (monitor picture) of display 12 being carried out the concentration of the input picture shown or color for adding the mixture of colours, therefore comprising the device being converted to mixing of losing lustre.

It is desirable that, in the image photographed by two cameras 16, the ratio of picture size is adjusted to identical.That is, such as, a camera 16 can be utilized to take benchmark image, similarly, utilize another camera 16 to take benchmark image, these shooting images are compared, obtain the Scalable ratio of image, then be adjusted to same size, zoom lens can be adopted to the camera lens of a camera 16, change size, change the distance between camera lens and shooting face, thus adjust, in addition, the travel mechanism of the distance adjusted individually along the movement of XY direction can also be installed in the camera.

In addition, in this pair of camera mode, even if there occurs the reference media 30A be placed on worktable 18 to input or position deviation with the size difference of inspection medium 30B, when the coincidence process carrying out input picture, by carrying out position correction and adjusted size to both benchmark images and check image in pixel scale, can picture registration be carried out, image is checked each other.

In addition, in two Camiera input mode, benchmark image and check image can be obtained by once shooting, therefore, they can be got up with the operation associated codes of Inspection as a paired file, and in being kept at HDD29 etc.Like this, a paired file under preserving can be used, carry out continuous self-verifying in the same manner as single Camiera input mode.

In addition, obtain image by single sweep instrument input mode or obtain image by single camera single sweep instrument input mode, and, obtain and carry out RIP process and the image of the printing that obtains digital (image) data or PDF data etc. according to PS (PostScript) data be input in data input part 24, the different machine compared in order to basis or view data, check with the hybrid mode based on input picture, the 1st view data 31 and the 2nd view data 32 can be generated, wherein, in single sweep instrument input mode, a scanner 17 is used to input continuously or input reference image and check image respectively, thus obtain two scan images, in single camera single sweep instrument input mode, a camera 16 and a scanner 17 is used to carry out continuously inputting or inputting respectively, thus obtain two shooting images and scan image.In addition, in these modes, same size can be adjusted to respectively by vertical/horizontal, or carry out the angularity correction of two input pictures, carry out individually checking or carrying out self-verifying continuously.

Any one party in benchmark image and check image be group version state and the opposing party for single page, group version page can be divided into single page, or carry out image retrieval, the image corresponding with single page image is extracted from group version page, and group version is carried out to each single page, overlap as group version page.

In addition, in the input media when carrying out scanner input or Camiera input, such as, about the independent page image of formation 8 pages group version, sometimes can not in position accurately from correct angle visual to, but be attached to mixed and disorderly position by hand.In addition, there is error in the stamp with the size of each page of sometimes fitting.When the picture registration carried out in this situation and difference check, according to each page, the Iamge Segmentation of laminating is become image-region, in units of each page, picture registration is carried out to every one page, carry out difference inspection.

To in the image input of printed article, the situation of thin paper being carried out to printed on both sides is described.In this case, in print inspection image surface, there is so-called back side print through phenomenon, inspection is had an impact.As for this inspection, remove the image rectification of back side print through, from back side print through mirror image, deduct the permeation parts of medium, be set to inspection image.Now, in surface image, at the part place of the print through picture registration with the back side, the image on surface is also subject to the impact of the image at the back side, therefore, be taken into the image at the back side as mirror image, and then deduct the transit dose of medium from the whole amount of the image on surface, blank parts of images mask (mask) is applied to check image face and checks.

In addition, in printed on both sides thing, when Camiera input or scanner input, in order to reduce back side print through, when inputting image reference media and inspection medium, if the paper placing black or Dark grey at the back side of medium carries out image input, then can bring the effect reducing back side print through.In addition, when scanner inputs, when being configured to check part (glide slope or the face) of medium just by CCD, CMOS of scanner or the light accepting part of laminating imageing sensor after by conveying roller, in order to make printed medium by scanner light accepting part face, in the opposition side across printed medium in scanner light accepting part face, there is printed medium pressure roller or the pressing plate with printed medium conveying function.By the color of this printed medium pressure roller or pressing plate is set to black or Dark grey, the effect of the paper of black or Dark grey can be replaced at the described back side, thus alleviate print through, the image of input media.

Below, as other example of applying in a flexible way, about the 1st view data 31 as benchmark image and the 2nd view data 32 as check image, benchmark image and check image can be preserved in advance in the video memory 28 or HDD29 of PC11, and utilize CPU21 and image control portion 23, by video memory 28, HDD29 or network line, read in, call or obtain the image generating benchmark image, check image or these both sides, also directly can read in, call or obtain the 1st view data 31 and the 2nd view data 32 that are generated by external unit.

But, such as, use audit by comparison software be taken into from camera 16 two images (benchmark image, check image) of carrying out image inspection and be kept at primary memory 22 provisionally, concentration (lightness), tone (chroma, form and aspect), contrast or gamma can be comprised.And, can be configured to: in advance by checking that setting table picture carrys out the inspection accuracy value of desired location deviation etc., such as, the 1st generated view data 31 and the 2nd view data 32 can be converted to data that are intermediate or binaryzation, and they are compared.

In addition, in the diverse situation of the input data of benchmark image and check image, for from printing machine, when the image of the output of laser printer or ink-jet printer etc., following situation can be produced: except the kind of output device, beyond the output setting of device or output accuracy, sometimes because of color or the material on output block surface, reflectivity, carry out the deviation etc. of the various factors such as the kind of inspection wavelength region may and the image checked, make the 1st generated view data 31 and the image of the 2nd view data 32 or the thickness of line segment or acutance different.

Like this, when the 1st view data 31 compared is different with the image quality of the 2nd view data 32 or the thickness of line segment, such as, (other image layer or other layer) picture registration (images match) is carried out to the 1st view data 31 and these two images of the 2nd view data 32, and show in the display frame of display 12, utilize the entirety of the image shown by instruction such as positioning equipment 15 grade, a position or multiple particular portion assign to carry out the adjustment of image, namely, carry out concentration (lightness), tone (chroma, form and aspect), contrast, the image quality adjustment of gamma etc., overstriking image or line segment respectively, coarse regulation image is added by the rotation process of image angle, or only using the central part of linear image as the line processization of key word etc. such subtract fine control, thus carry out the distortion adjustment of image.In addition, the filtration treatment that specifies or Image Adjusting process can be carried out, and then, the image procossing of the regulation of the various image correction process or Image Adjusting process etc. that comprise the color management process for carrying out hue adjustment etc. can be carried out.

That is, when the acutance difference of the image such as lens of the equipment of a and e of english lowercase character or numeral 6 and 8 etc., shooting word segment, actual conditions are, the precision of audit by comparison is poor.Carry out in the image checked at two, such as, when the thicknesses such as word are different, carry out the image procossing of the center line of the line image part of taking out word, form so-called key word, carry out the audit by comparison of text.

In addition, in the image-region of the word of two images carrying out checking, examiner carries out picture registration, while observe (replacing) display of staggering of two images, although the different group of text that still word is identical of visual identification thickness on one side, utilize positioning equipment to draw a circle to approve the image-region being identified as identical group of text to limit, in PC and audit by comparison software, be identified as the dot image of formed objects.And then, carry out the image correction process that the thickness of line segment is conformed to benchmark image or check image, thus, carry out the image procossing that can carry out identical evaluation to two images.

At the different image of the thickness of the line of the character area part to two images produced by different RIP, image resolution ratio each other or when comparing each other based on the image that the acutance such as image of printing view data and Camiera input (shooting) is different, due to the difference of the profile of image slightly, demonstrate the discrepancy as check image mistake.

At this, in order to the subtle difference produced by the profile of such image too much can not be detected, apply Fuzzy processing, inspection threshold value is controlled, under described inspection threshold value, thus only to link a certain fixation element, the profile of lines that the such as above pixel of tens of pixel links in long way carries out the control of inspections threshold value.But, when the image that the contiguous pixels shorter at contiguous pixels, such as to detect by concentration in one image be individually less than 50% is formed, likely be detected as dust etc., by programming to inspection step, make to apply Fuzzy processing, thereby, it is possible to make lines be separated with misprints (inspection impurity) such as dusts.In addition, the value of the Fuzzy processing of word and color sets individually.

In the image procossing of such regulation, section adopts the following method of being undertaken by PC11 in advance: according to intermediate value adjustment the 1st view data 31 and the 2nd view data 32 of thickness difference, or any one view data is mated with another view data any, or such as, in described image correction function, use curve correction, color table (description document) or color conversion engine, adjust image by image correction function, make at least to mate with any one view data.About description document, such as, can use the public description document of the ICC of each input equipment colored description document or JAPANCOLOR etc.Like this, the quantity of discrepancy (mistake) E caused by tonal difference can be reduced, carry out more accurate image inspection.

In addition, when utilizing 1 Bit data of the site representing printing as benchmark image or check image, such as, sometimes there is following site information: view data is such as 2400dpi, resolution is very high and data capacity is very large, when carrying out conversion of resolution, the decorative pattern as folded line is easily caused to lead to a phenomenon.In this case, because data capacity is large, therefore before carrying out picture registration, in order to be converted to the image of the gray scale with 8 bits and prevent folded line, such as, while the process carrying out making site dizzyization temporarily, the Edge contrast again of image is carried out, or carry out conversion of resolution, eliminate the folded line caused by halftone dot image thus and produce.

In addition, before carrying out picture registration process, the rotation process of the angularity correction of input picture when carrying out for taking accurately, and carry out, for the size adjustment process making two images become same size, forming CMYK4 look tertiary colour image.Using they final output images as printing, utilize in the check image for comparing with the basic data (PDF or TIFF-CMYK image) of the complete paper in school or printing.Certainly, utilized by the benchmark image of the base image as printing, such as, in press, also may be used for the sampling check of the printed article printed out.

When image-input device white rank and black rank changes or color reproduction changes, also can not get identical result even if carry out checking with identical inspection threshold value.Its reason is cause by mainly as the camera of image-input device or the variation of scanner as a rule, needs to use special chart to carry out the adjustment of input media or calibration etc., thus the image reproducing that can be fixed.

Special chart is such as that it is certain value for making limiting threshold value as checking the check image adjusting diagram of benchmark, makes in which position to carry out checking all to obtain identical check result.The content of chart is: in order to check word, in the result that words different to the thickness of word, shape (font) or character size (counting) is arranged stepwise, comprise word different or slightly deviation or the different situation of thickness, which automatically detect this subregion with character size to be found, by specifying character size in advance, automatically detect inspection threshold value.

In order to the confirmation of checking on the quality making examiner utilize checkout facility to carry out under permissible accuracy, be made check image adjusting diagram, this check image adjusting diagram is for simplifying the suitable threshold value setting in inspection.This image inspection adjusting diagram such as brings following effect: in order to carry out the audit by comparison of the 1st image and the 2nd image, under the inspection precision required, obtains optimum threshold value easily.

In addition, this check image adjusting diagram is formed with the two kinds of charts that compare of control chart by carrying out benchmark chart.In addition, this chart prints or exports in the identical medium carrying out checking.In addition, in this check image adjusting diagram, add the inspection size of word, color difference, as the stains of the printed article of printing defects or the drop of word, the pin hole of image and check time the key element such as dust.

In addition, this check image adjusting diagram is using one as the view data of benchmark or the benchmark chart that exports according to its data, character string is such as change to the white background of foreign language such as Japanese and English of the character size of about 20 and the breviary of the word of black background and fullstop/question mark/bracket/stress etc. from 4, in addition, forms etc. add the content having form line, the cromograms such as configuration IT8, plain net (screentint) or gray scale, in addition, be configured with the image such as photo or illustration, the face of such as people, landscape, flower, the pottery chinaware of black and white, word design or sample mark etc.

In addition, relative to the benchmark chart of check image adjusting diagram, control chart works in the case where there: by the font of word or image or size or the different position of color, the position having changed word, deletion or insert a word or multiple word position, changed the position of word or image, the position of word or image or towards different positions, the special color patch or site etc. of yellow solid concentration or light color be superimposed upon in blank or black background, be configured as drop word, thus, the inspection precision to various inspection thing is set further.

As described above, be made and there is almost check image adjusting diagram, in this check image adjusting diagram, hope is made to have the gray scale of several rank as character size concentration or form and aspect/chroma etc. that the difference of benchmark chart and control chart carries out detecting, and for the word of the correction of chart or the precision of images, set the threshold level that the concentration difference that can detect hope or tonal difference detect.

And then, based on as each check image adjusting diagram of benchmark image and check image and printed image data thereof, such as, inspection is compared under the threshold value wanting the permissible level being judged as non-defective unit, thus, confirm to carry out the spot size of the word checked or the tonal difference of color according to Δ E or CMYK%.In addition, in printing process, the threshold value can carrying out character size inspection and the tonal difference acceptable threshold based on this threshold value is delivered to associate printing workshop, Yin Qian department or operating department.

And, when employing the image be taken into by image-input device, according to the characteristic of the input media arranged separately all departments, carry out the coincidence pre-service setting that size or the distortion of image are corrected individually, and optimum inspection threshold value of applying in a flexible way, thus, there is the advantage enabling printing firm unify the quality management benchmark between whole intra-company or outsourcing.In addition, by optimum inspection threshold value of applying in a flexible way, the image be taken into by the image-input device arranged respectively agency etc. can also be used.

In addition, having the 1st view data 31 of printing net-point or the 2nd view data 32 is when generating according to the shooting image obtained by scan image or the camera 16 of scanner 17, produces so-called folded line sometimes according to the read-out resolution of scanner 17 or camera 16.In this case, by the adjustment of the scanning resolution to printing net-point, scan with the resolution being difficult to produce folded line, or, utilize folded line to remove software and site dizzyization based on soften handled of benchmark image and check image carried out to image during input or the image that inputted and acutance is strengthened.Or, can carry out printing or after further digitizing, obtaining inspection image printing net-point being become the unconspicuous FM screen of folded line etc.

In addition, when the 1st view data 31 or the 2nd view data 32 be read by scanner 17 generated at medium 30B prints out for reference media 30A or check benchmark image or check image by printing machine, as mentioned above, during the wet condition that ink is not dry after just printing, produce fault sometimes.

That is, at scanner 17 when reading reference media 30A or checking wet condition on medium 30B black, read under the state sometimes contacting with conveying roller or the image reading unit of scanner 17 and have stains in printed article.Under these circumstances, image inspection accurately can not be carried out.

Therefore, as shown in Figure 6, use medium holding plate 39, this medium holding plate 39 is by reference media 30A or check that medium 30B remains and can read non-contiguously with the conveying roller of scanner 17 or image reading unit.And then, on this medium holding plate 39, coating makes reference media 30A or checks that medium 30B installs and removes sorbing material or cementing agent freely, or utilize the double faced adhesive tape etc. that can again peel off to fit, and utilize mask (mask) frame round the periphery of medium.By such medium holding plate 39, inspection medium can be made not to be transferred roller and to pollute and carry non-contactly.

Thus, medium holding plate 39 is arranged on the reading part of scanner 17, thus the reading face of alignment scanning instrument 17, such as, even if image surface is down, proof or printed article also can be made not to depart from from the plate of medium holding plate 39 and read, obtain scan image.

In addition, by offering trickle hole on whole of this medium holding plate 39, placing and check medium and carry out air adsorption from lower surface, thus, deflate and become complete adsorption plate.And, in medium holding plate 39, the adsorption paper with adsorption function is fitted onboard, therefore, does not need expensive adsorption plant, become the medium holding plate that price is cheap and easy.In addition, also can in the following way: by blowing out strong air from the downside of plate, paper is attached to upper plate, thus fits equably.Therefore, having can in the convenience needing to carry out applying in a flexible way in the whole devices checked.

Next, as described above, in video memory 28 store the 1st view data 31 and the 2nd view data 32 at least partially each other, namely benchmark image in whole or in part and check image such as carry out accordingly in pixel scale in whole or in part picture registration (images match) process.In addition, in the image testing device 10 of the 1st embodiment, for the image of the 1st view data 31 and the 2nd view data 32 of carrying out picture registration, in the display frame of display 12, the discrepancy image compared is set to different colors and carries out picture registration by utilization each other, or alternately switches (staggering) display, in addition, carry out show tags frame with same color or different colours, or in display frame the presence or absence (ON/OFF) of alternately show tags frame.In addition, discrepancy image can be made further and show with alternately switching (staggering) with the image of indicia framing round discrepancy, making examiner easily confirm discrepancy image.

Specifically, picture registration process carries out picture registration to make the 1st view data 31 and the 2nd view data 32 precision, and pixel scale carries out picture registration correspondence, in picture registration process, as the inter-process of the process that overlaps, carries out two steps continuously.In the 1st step, carry out the pre-service of the preparation for the environment that overlaps.Namely, carry out as described abovely adding coarse regulation or subtracting the resolution adjustment in the correction of fine control etc. and the public coordinate axis of two images, and then by the poor adjustment of vertical with horizontal relative picture size, the removal of relative scalloping, picture position corrects, picture size corrects and image angle correction adjusts.In addition, in the picture registration process of the 2nd step, such as, use the various known method of unique point coincidence, coincidence, multiple spot coincidence, Factorization algorithm coincidence or any segmentation coincidence etc. at 1, carry out the coincidence of position alignment.

As mentioned above, in utilization, in single job, when the different positions adjustment of image, anglec of rotation adjustment or the adjustment of adjustment size are excessive, depart from when once adjusting permissible range and cannot adjust, be divided into more than twice, carry out program as additional adjustment (additional adjustment) process.In addition, image control portion 23 in order to make the input picture of benchmark image and check image towards aim at or in order to erect image on monitor picture towards showing, by making image rotate freely the function of certain angle with 90 ° of units in principle, such as, when splitting the characteristic of device or group version page or when multiaspect group version being carried out to check image when changing benchmark image and angle, make image towards unification.Like this, carrying out angle initialization in the front and back checked, carrying out angle rotation then and there when checking, in addition, use image feature for can only carry out the printed article inputted etc. from the back side, thereby, it is possible to make benchmark image and check image towards or direction consistent.

In addition, before picture registration process is carried out to the benchmark image be stored in video memory 28 or HDD29 and check image or after carrying out picture registration process, can carry out is the Iamge Segmentation process of multiple area image by Iamge Segmentation, and concrete condition will be described below.And then, the 1st image section region group data of each area image that are partitioned into and the 1st view data 31 of the 2nd image section region group data and the 2nd view data 32 process unit as later each process will be represented, utilize the part that a threshold value or multiple threshold value inspection are partitioned into, and carry out showing and preserving.

In addition, in utilization, in benchmark image and one or both in check image respectively because hand pastes (Shou Stickers) etc. and image each several part and corresponding image size or image be pasted into angle is distinguished different, for each each subregion self-corresponding, automatically or by positioning equipment be subregion by Iamge Segmentation, picture registration process is carried out to each subregion.

In addition, such as, if according to being the carve information opened of A4 by the Iamge Segmentation opened of A1 after group version and adding the template having group version page information, page number is given to the subregion image of the image both sides checked, then give A to benchmark image, in addition, give B to check image, be kept in working folder, then can carry out the Automatic continuous batch processing checked.In addition, on the contrary, according to page group version information, make the file after segmentation and single page order, open the group version images match of duplex page order or presswork, carry out image combination, thus check all sidedly.

In addition, can in the benchmark image be stored in video memory 28 or HDD29 and check image, by the identical parts of images of the image such as text or pattern, namely the text being positioned at the position corresponding with the content images of identical position or subregion described later or pattern etc. is formed, there is the image of the part of identical content element and the order association of image inspection, or go out the image corresponding with the same section further described below by image inspection process image zooming-out, and associate with benchmark image and check image, the parts of images these associated is as the 1st view data 31 and the 2nd view data 32, carry out picture registration.

Next, the image testing device 10 of the 1st embodiment is such as by using audit by comparison software, 1st view data 31 and the 2nd view data 32 of having carried out picture registration are compared, extract the concentration (lightness) between these two view data 31,32, tone (chroma, form and aspect, L*a*b* value or Δ E value) and position deviation etc., detect difference.

Difference can be: as rgb value, CMYK value, CIEXYZ value, the L*a*b* value of the color data of image; Based on the aberration (Δ E, CIEDE2000 etc.) of concentration value, colour atla table colour, point light value, reflectance-transmittance rate; Or according to the image that infrared wavelength, ultraviolet wavelength and x-ray wavelength etc. obtain.In addition, about difference, can be separated and compare concentration and the tone of the color of the 1st view data 31 and the 2nd view data 32, detecting respectively.

As the concrete example being separated concentration and tone, such as, can enumerate: after the 1st view data 31 and the 2nd view data 32 are converted to L*a*b* data, be separated into L value and a*b* value; Or be separated according to lightness, chroma, form and aspect.In addition, compare about data, can as described above, such as, carry out each other in data that are many-valued or two-value.

About before changing with change after the inspection of color of image, the description document of input equipment and the monitor description document of output device can be used, carry out L*a*b* conversion to CIEXYZ image or RGB image, the data as the site % or ink amount that represent CMYK show.In addition, the CPU21 forming the Differential Detection portion 4 played a role as above-mentioned differential sensing units after the tone of the 1st view data 31 and the 2nd view data 32 is converted to L*a*b* value from CIEXYZ or RGB image, can be converted to aberration Δ E or CMYK to detect difference.

As shown in Figure 4, as difference one example, such as, in the 1st view data 31 and the 2nd view data 32 by when the check image line shown in line segment S there are differences point (mistake) E, detect and check the mark.Show in image at the discrepancy completing the check result discrepancy display view data 33 of picture registration shown in Fig. 4, the check image line of line segment S there are differences a little, therefore, such as with can the mode of visual identification, with show tags frame 34 round this discrepancy display area (mistake display area).

As shown in Figure 7, after detecting difference, such as, the difference of multiple threshold value (TH1 ~ THn) to the 1st difference image detected and the 2nd difference image is utilized to compare.In addition, about this multiple threshold value, such as, examiner can set arbitrarily/change by using input such as the operation of mouse 13, keyboard 14, positioning equipment 15 etc.Or, also according to what threshold value of the front and back of the threshold value of basic settings can check.In addition, as mentioned above, no matter be simple threshold value or condition threshold, all can apply in a flexible way.

When needing to make the inspection precision severization in a part of region in the whole image carrying out checking check, such as, only will mark the subregion such as assumed name or two-dimensional bar as close examination position in advance, set strict threshold value, thus, only utilize the threshold value different from entirety to set to this position, thus check uniformly according to multiple threshold value simultaneously.In addition, also can carry out merely the segmentation in check image region, to after each segmentation, threshold value that the section sets of especially specifying is other, other non-setting section is set to the identical threshold value registered as standard, thus checks according to multiple threshold value.

And, known: when to obtain for the multiple threshold value of whole image setting multiple difference image compare each other, if shown continuously according to each threshold value, then discrepancy display part figure place can increase and decrease variation.Owing to can there is the 1st view data 31 and the 2nd view data 32 checkout discrepancy point each other of each threshold value of increase and decrease to this discrepancy display area, therefore, as mentioned above, using this discrepancy as discrepancy display area, indicia framing 34 etc. can be utilized to surround discrepancy display image and to show.In addition, as shown in Figure 8, such as, the numerical value of threshold value is less (checking that precision becomes strict), then based on the difference of multiple threshold value and the quantity of the discrepancy (mistake) of result based on the comparison more, the numerical value of threshold value larger (checking that precision becomes loose), then based on the difference of multiple threshold value and the quantity of the discrepancy (mistake) of result based on the comparison fewer.As mentioned above, in the region of not carrying out checking, do not set threshold value, or threshold value is set to 0.

In addition, select the subregion of (setting) whole image, utilize multiple threshold value to check uniformly simultaneously, at the discrepancy display image when observing with display of staggering of the check result to the threshold value based on two or more than three, in multiple threshold value, for subregion image, optimum threshold value easily can be selected.In addition, equally, first, when hope utilizes optimum threshold value to check each subregion of the image of the inspection thing (medium) as benchmark, benchmark image and check image are split in the same manner, such as, coordinate the inspection threshold value originally set, utilize the threshold value of strong and weak several grade to check uniformly simultaneously, for each image of the subregion in segmentation, show separately or in a view, select and preserve, to select the discrepancy display image of optimum check result from the discrepancy display image of the check result checked out according to multiple threshold values of the several grade of power uniformly respectively.The threshold value of the subregion selected, in checking below, can be worth by default and carry out preserving/utilizing.

In the discrepancy image file of each rank that is corresponding with the independent subregion of the image carrying out checking, multiple inspection threshold level, can respectively to the display image additional setting layer of the identification colors of discrepancy, and save as discrepancy display image (hereinafter referred to as " discrepancy display image ") of check result.In addition, the discrepancy display image of the check result under preserving, all easily can carry out the switching display of each inspection threshold value and the display of color differentiation.

At this, when having carried out the image input for individual inspiration, installing printing machine, the situation that input media etc. carries out based on the inline self-verifying of input is continuously inferior, easily can select optimum threshold value according to the number of the discrepancy of each threshold value in respective multiple threshold value.In addition, even if in the PC without audit by comparison software, also can download simple and easy (display) view software of in addition exploitation, the discrepancy for the check result in above-mentioned shows image, confirms the difference based on threshold value.

In the image testing device 10 of the 1st embodiment, be conceived to use such multiple threshold values, according to the discrepancy display image of each threshold value, generating can the discrepancy display view data of visual identification discrepancy display area.As shown in Figure 9, the discrepancy of each threshold value display view data 41 ~ 45, such as, utilizes indicia framing 34, with can the mode of visual identification, the discrepancy display area corresponding with threshold value be shown as discrepancy display image.

Cong, in the example shown in Fig. 9, generates the discrepancy display view data 41 ~ 45 that the display mode of the quantity of this indicia framing 34 in the discrepancy display image of each threshold value or the area of discrepancy part etc. is different.In addition, the discrepancy display view data 41 ~ 45 of these each threshold values generated such as can be kept in video memory 28 or HDD29 as the check result discrepancy display view data 33 of Rotating fields.

Check image is divided into subregion, gives the threshold value of each this subregion, for concentration difference, aberration or tonal difference, carry out check result by each subregion and whether to conform to the check result display of display or carry out zero × judge display.

Necessary part in check image is split, for each partitioning portion region, utilizing the threshold value of specifying to check, when revising the threshold value of the parts of images be partitioned into, can preserve according to this revised threshold value.In inspection afterwards, also can check according to the threshold value after changing, the positional information of the part of this segmentation and threshold value are preserved/registered, can call at any time, thus apply in a flexible way.

In addition, in image testing device 10, according to difference image and the comparative result of the number based on above-mentioned such multiple threshold value and indicia framing, such as, when observing continuously each threshold value, when threshold value changes, discrepancy number positional increases sometimes sharp, can for each threshold value, use the algorithm of the regulation of the threshold value calculated before discrepancy number positional just will suddenly increase, threshold value is defined as limiting threshold value, generates the discrepancy display view data 44 based on this limiting threshold value.

Herein, limiting threshold value is the threshold value that can detect discrepancy (optimum), and, be the threshold value of the limit under the condition of the subtle difference point that can not detect the position not being discrepancy.In addition, (such as, view data 43 can be shown to discrepancy display view data 41 and discrepancy) each other to the discrepancy display view data of different threshold values respectively and compare, generate the discrepancy display view data based on this comparative result.

In addition, image testing device 10, such as by using audit by comparison software, uses the discrepancy display view data 41 ~ 45 of each threshold value generated to carry out various image inspection process.In image inspection process, such as, can enumerate: for the discrepancy display image of each discrepancy display view data 41 ~ 45, in the display frame of display 12, use different identification colors (red to discrepancy display image, blue, yellow etc.), so that visual identification the mode of discrepancy display area can be gone out, alternately or successively switch the discrepancy display image of ground display each threshold value plural, the respective discrepancy image of the multiple inspection threshold value of mark display, in addition, carry out the ON/OFF display of the indicia framing of discrepancy image, in addition, carrying out staggers display and mark display simultaneously shows.In addition, also show by overlapping or guide look the multiple discrepancy images identified according to identification colors, display is attached with multiple discrepancy images of the ON/OFF function of indicia framing in a view, makes easier Recognition Different dot image.

Like this, in order to will the detection of the discrepancy changing threshold value do not needed to reduce to the limit, find the threshold value of the optimum that can find necessary word drop or dust/damage, need to improve or reduce threshold value, in order to easily confirm how its result changes, need to make the state of the state of the mark of the discrepancy display area of initial inspection threshold value and the mark of other threshold value automatically carry out alternately, thus switch ground display frame, or utilize positioning equipment in the mode of a touching, picture is alternately shown with switching.

In addition, by using the discrepancy display view data 41 ~ 45 of each threshold value, in image testing device 10, multiple threshold value can be utilized simultaneously to carry out image inspection uniformly, thus obtain suitable check result.Thus, examiner such as by observing the discrepancy display image of the check result discrepancy display view data 33 demonstrated in the display frame of the display 12 shown in Fig. 4, easily can detect the discrepancy of (between the 1st view data 31 and the 2nd view data 32) between benchmark image and check image.Therefore, whoso, can not had error by an image inspection and is easily carried out the image inspection of certain rank.

So far, described content compares the word or tone etc. of benchmark image and check image, utilizes a threshold value to show the discrepancy image of the difference of the image of the part of its correspondence, and show round difference with indicia framing.But, such as, check medium as the bubbles such as the thin stains on the paper carrying out checking or ethene etc. sometimes and produce inappropriate situation.In this case, the 3rd threshold value needing the 1st threshold value that printed part is checked and the 2nd threshold value and the part of the dielectric materials such as paper is checked.In addition, such as, in color etc. checks, sometimes need the change confirming stains or color for each colour of solution such as red, blue or yellow, thus need the n-th threshold value.

In addition, on the other hand, although in order to the emulation inspection also not carrying out the discrepancy shown for there is some differences can be carried out, multiple threshold value of applying in a flexible way.Such as, threshold value is set in order to the quantity of limit markers frame display.This is because, such as, exist in the different word of thickness (Gothic and Ming Dynasty's body etc.), or, even identical word, digital picture and there is concentration difference from the word the image that camera etc. inputs.Emulation inspection is carried out as same image in order to be not identified as discrepancy image, for this reason, such as, tackle as follows: the word large to concentration sets high threshold value, and cut down (cutoff) high concentration, do not carry out the evaluation etc. of the concentration of more than finite concentration, thus the inspection that the concentration difference that can carry out not causing the difference by word is evaluated.

In addition, when the contrast of the image making evaluation region that enter low strength range, that be weakened (cutin) returns to original, contrast can be improved linearly, but, utilize Log to change to make middle gray scale less change or square conversion (y=x ²) etc. concentration is changed, expand the concentration difference of noise level and check image.Thereby, it is possible to check as follows: even if improve lower threshold value further, more remove noise, also can not bring impact to the detection of discrepancy image.

Like this, to carry out mark display with frame round the mode of the discrepancy image generated according to the word of benchmark image and check image and the difference of tone, but also can arrange and the other threshold value limited is shown to this mark, thus, such as, the discrepancy image that counts, not show tags frame is carried out as discrepancy for not needing.In addition, by the threshold value of setting for carrying out the evaluation different from the inspection threshold value for generating discrepancy image, thus, such as, the display of discrepancy image can be made at least to find dust or stains thus carry out mark to show.

In addition, such as, in discrepancy display image, when when there are differences discrepancy display area place a little not show tags frame 34, or when representing that the discrepancy display area place of less desirable discrepancy or unnecessary discrepancy shows indicia framing 34, such as, can by operation positioning equipment 15 etc., the discrepancy of the check result discrepancy display view data 33 that the display frame of display 12 shows shows indicia framing 34 that is additional in image or deleted representation discrepancy display area.

And, when indicia framing 34 will be added, the image inspection scope needing the part of carrying out discrepancy display can be specified, add indicia framing 34, thus, according to integral image, automatically threshold value is corrected, the difference in the image section region needed for extracting/generating, thus automatically obtain the discrepancy threshold value in the region that can detect the discrepancy display area corresponding with this indicia framing 34.In addition, on the contrary, when wanting delete flag frame 34, the image inspection region not needing the display section of carrying out discrepancy can be specified, delete flag frame 34, thus, in order to do not detected the mark result of the discrepancy in the region of the discrepancy display area corresponding with deleted indicia framing 34, automatically threshold value is corrected, from integral image, delete the indicia framing 34 of required image part.Now, also can show tags frame 34 add or delete vestige.

In addition, such as, when carrying out image inspection in the 1st view data and the 2nd view data of the image at expression word, such as, when producing the excessive deficiency of a word or several word because of word amendment operation, even if character string is below identical, but all show as different parts later, in practical, word inspection cannot be carried out.Therefore, in the case of necessary, image testing device 10 can automatically extract String Region or utilize positioning equipment that the examination scope of the image comprising the quantity of excessive not enough word is generated as the 1st view data and the 2nd view data again, again carries out image inspection.

In addition, image testing device 10 can carry out the image inspection paying attention to particular color.Especially, for Y (yellow) though the color being or 100% patch concentration visual time also more shallow special color etc., it no matter is visual or equipment inspection, all be difficult to carry out image inspection, therefore, under these circumstances, be set to following concentration value or L*a*b*, carry out image inspection.In this case, specifically, such as, for the image inputted by input equipment such as camera 16 grade, the 1st view data and the 2nd view data from taking image is made to carry out picture registration, after the concentration detecting examination scope (inspection part) according to PPF data, PDF, 1 bit tiff printed data etc. or L*a*b*, differential comparison is carried out to from the concentration data of described PPF data etc. and the concentration data of the 2nd view data, thus carry out image inspection, thereby, it is possible to check reliably.

In addition, above-mentioned each process is by such as graphics processing unit, differential sensing units, image generation unit, realizes as the audit by comparison software etc. installed or preserve in PC11, CPU21 of image inspection unit and primary memory 22.The discrepancy display view data 41 ~ 45 in check result discrepancy display view data 33 or each several part region is included in the data relevant to check result, discrepancys display images based on these display view data 33,41 ~ 45 such as can utilize the GUI structure of regulation, are presented in the lump in the display frame of display 12 with the data comprising the word that represents check result or numeral etc.

As mentioned above, in the image testing device 10 of the 1st embodiment, picture registration is carried out to detect difference to the 1st view data 31 and the 2nd view data 32, for the difference detected, the discrepancy display view data of each threshold value in the multiple threshold values set by generation.And then, use these discrepancys to show view data and carry out image inspection, therefore, such as, can image inspection special as follows be carried out.

As shown in Figure 10, such as, the discrepancy display image of the check result discrepancy display view data 33 that the display frame of display 12 shows shows as follows: to show the mode of image 51 ~ 58 image based on the discrepancy of multiple area images corresponding with subregion, multiple inspection portion 1 ~ 8, be divided into 8 matrix images.As mentioned above, these each area images form process unit respectively as the 1st view data 31 and the 2nd view data 32.Therefore, in subregion, each inspection portion 1 ~ 8, such as can demonstrate the discrepancy display image 51 ~ 58 showing indicia framing 34 (not shown) etc., wherein, show the discrepancy that indicia framing 34 represents the discrepancy display view data based on different threshold value.

Namely, in the example in the figures, in subregion, inspection portion 1,6,7, indicia framing 34 can be utilized, so that the visual identification mode that goes out discrepancy display area the discrepancy display image 51,56,57 of the discrepancy display view data based on threshold value A can be shown, equally, in subregion, inspection portion 2,4, in 5, show the discrepancy display image 52 of the discrepancy display view data based on threshold value B, 54,55, in subregion, inspection portion 3,8, show the discrepancy display image 53,58 of the discrepancy display view data based on threshold value C.

The indicia framing 34 of the discrepancy display image 51 ~ 58 in subregion, each inspection portion 1 ~ 8 such as can as described above, for each threshold value A ~ C, show etc. under the state of giving the different identification colors such as redness, blueness, yellow respectively.In addition, the position of subregion, each inspection portion 1 ~ 8 or scope such as can, by employing the operation input of mouse 13, keyboard 14, positioning equipment 15 etc., be carried out arbitrarily setting/changing by examiner.

Like this, represent benchmark image and check image two view data 31,32 check result, in the discrepancy display image of check result discrepancy display view data 33 that shows in the display frame of display 12, for each subregion, inspection portion 1 ~ 8, represent the discrepancy display area of the discrepancy (comprise image error, misprint or revise position etc.) corresponding from different threshold value A ~ C, such as, show by indicia framing 34 etc.Thus, examiner, by the display frame of observation display 12, easily can detect the discrepancy between the 1st view data 31 in subregion, each inspection portion 1 ~ 8 and the 2nd view data 32.

In addition, as mentioned above, with multiple subregions image for process unit, generate discrepancy display view data, carry out image inspection process, therefore, examiner is by operation input, the threshold value of each subregion, inspection portion 1 ~ 8 is suitably changed, thereby, it is possible to the display mode freely changing indicia framing 34 grade of display in discrepancy display image 51 ~ 58 shows.

Such as, if the inspection precision of the threshold value A of subregion, inspection portion 1 is changed lower, display or the display area of the indicia framing 34 then on discrepancy display image 51 reduce, on the contrary, if the inspection precision of threshold value A will become very high, then display number or the display area of the indicia framing 34 on discrepancy display image 51 will increase.In subregion, each inspection portion 1 ~ 8, freely can carry out such image inspection.

And, as mentioned above, owing to the process unit of the 1st view data 31 and the 2nd view data 32 can be set to the subregion image after segmentation, therefore, can the position of expectation in subregion, each inspection portion 1 ~ 8, further free setting carried out to subregion, inspection portion 1a ~ 1e or carry out Factorization algorithm and set, thus in the subregion 1a ~ 1e of each inspection portion, carrying out the image inspection of the discrepancy display view data employing different threshold value respectively.

Figure 10 shows: such as, and in the subregion, inspection portion 1 of display discrepancy display image 51, setting subregion, inspection portion 1a ~ 1e further, becomes the state demonstrating the discrepancy display image 59 comprising discrepancy display image 61 ~ 65.In the subregion 1a ~ 1e of each inspection portion, also can show the indicia framing 34 etc. of the discrepancy of the discrepancy display view data representing different threshold value respectively.

In the example in the figures, in the 1a of subregion, inspection portion, indicia framing 34 can be passed through, so that the visual identification mode that goes out discrepancy display area the discrepancy display image 61 of the discrepancy display view data based on the numerical value of color threshold B and the numerical value of concentration threshold B can be demonstrated, equally, the discrepancy display image 62 of the discrepancy display view data based on the numerical value of color threshold A and the numerical value of concentration threshold B is demonstrated in the 1b of subregion, inspection portion, in the 1c of subregion, inspection portion, demonstrate the discrepancy display image 63 of the discrepancy display view data based on the numerical value of color threshold C and the numerical value of concentration threshold B, in the 1d of subregion, inspection portion, demonstrate the discrepancy display image 64 of the discrepancy display view data based on the numerical value of color threshold B and the numerical value of concentration threshold A, in the 1e of subregion, inspection portion, demonstrate the discrepancy display image 65 of the discrepancy display view data based on the numerical value of color threshold B and the numerical value of concentration threshold A.Like this, also can easily detect between benchmark image and check image between discrepancy.

In addition, in image testing device 10, no matter benchmark image and check image are expression images in whole or in part as described above, are the little and narrow area image or the parts of images be mapped that are split to form further by parts of images, and can process as the 1st view data and the 2nd view data.Therefore, can the view data of the benchmark image before the various inspection of expression be kept in HDD29, according to the view data represented as the image of one of check object, from the multiple images in HDD29, automatically retrieve and extract the view data of the image representing inspected object, and process as the 1st view data and the 2nd view data.

Specifically, such as, when representing the view data of the image of word, figure, pattern etc. as check object to PC11 input, image based on inputted view data is generated as the 1st view data.And then, the view data that automatically his-and-hers watches are shown as the image of inspected object carries out image retrieval, or retrieve and extract the view data associated by corresponding job name in advance, after being the 2nd view data by the Computer image genration based on this view data, picture registration process etc. is carried out to these the 1st view data and the 2nd view data, carry out image inspection, wherein, described inspected object carries out with the image of the view data based on this input checking corresponding, same shape word, figure, pattern etc.

About image retrieval, such as can after have selected the character string of medium or a part for Graphics/Image that will check printed article, by work data instruction or through image retrieval process technology, from the character string or photograph image etc. of the dielectric image compared, automatically extract similar image, check and show difference.In image retrieval process; PC or portable information terminal equipment can be passed through; retrieve and extract the intrinsic information (inherent feature that in the colouring information of image, video or video, the video such as shape of object has) of the image photographed, or retrieve and extract the result after by view data hashed.In addition, the technology that the video or information of preserving similar or identical object are retrieved is used.In the image of the electronizations such as HP/ e-book, electronics leaflet, electronic newspaper, retrieve too.

When the inline inspection in printing, have employed as under type: using school complete paper, the OK list checked out or as the image such as PDF, JPEG or TIFF of the base image of printed article for benchmark image, the check image in printing can be inputted them continuously, carry out overlapping and comparing.When inline inspection, can according to multiple threshold value multiple set, multiple check result is shown in real time in monitor picture, automatic decision is carried out in inspection imposes a condition, or show abnormal in monitor picture, carry out the display judged to examiner's (press operator) request.

When carrying out Automatic continuous batch processing inspection, carrying out checking that corresponding identical job name is each other according in the consecutive job names such as job number order, such as, if benchmark image is A image and add A in job name, if check image is B image, and add B at job name, thus be set to an image or be set to each page of respective image, or, further in the image of each subregion of each page, carry out the threshold value setting of multiple inspection benchmark respectively, carry out continuous review by automatic batch processing.In this case, such as, for multiple inspection threshold value, multiple settings can be carried out by the threshold value of ± 1 grade.

Now, as the pre-service of batch processing, can according to group version composition information, input picture after the page group version of printing machine is divided into each single page respectively, for the segmentation image of 1 page of unit, segmentation page graphical arrangement is stack states and is kept in identical file, in addition, benchmark image and check image are kept in identical file folder, in units of 1 page, compare inspection by Automatic continuous batch processing.

In this case, benchmark image uses identical image in checking at 1 time, but in check image, when producing printing concentration, stains or word drop etc. in the variation because of printed state, image changes sometimes, therefore, benchmark image is saved as source images, and the source images under use preservation, as benchmark image, carries out picture registration with check image in real time, thus, the audit by comparison of image is accurately carried out all the time.In addition, about threshold value, it is further preferred that obtain the threshold value of the front and back of the threshold value being considered to optimum, from wherein selecting simultaneously.Next, utilization example is below described.

In order to improve the efficiency of Inspection, according to the work unit of correspondence, need repeatedly automatically to process continuously.But, there is following situation: be not single page at the benchmark image compared and these both sides of check image, one side (consider printing sheets folding) is the image of the state after page group version, and the opposing party neither single page, and has carried out group version opening under viewed status.

This operation comprises the operation that group version page is divided into single page by (1).When splitting, what (2) needed the unwanted picture of the surrounding for removing page (do not use as printed article, the part dismissed) cuts out operation.It is further preferred that in order to automatically carry out this operation, in each page, carry out the setting of cutting out linea angulata.In addition, (3) carry out the setting of dividing method.Such as, left and right 2 segmentation, up and down segmentation, upper and lower 2 segmentations and left and right 4 are split, be folded into " (top) is aimed at above " or " (bottom) is aimed at below ", and then, need to carry out the appointment of beginning page or folding several inferior indicative input.

In addition, (4), when carrying out automatic reclosing, with any one in benchmark image or check image for benchmark, are automatically retrieved according to filename or thumbnail image, are become image.When the side image etc. that to be digital picture, the opposing party be made by DTP software be by scanner or Camiera input, in the concentration of two images, produce difference.When concentration there are differences, need carry out colour examining by image surface colour examining function described later and be converted to dot area percentage (%), and carry out the gray correction of data, make the concentration of the middle tone of data identical with the opposing party, thus, (5) can not produce the difference of image because of the tonal difference of the image of both sides.

In addition, the image (6) carrying out checking is divided into cancellate matrix in length and breadth, carries out picture registration.In addition, if there is the very thin word or the difference of fuzzy problem (feint problem (levelofunsharpness: lack unity and coherence clear)) of line or the difference of the thickness of line that are caused by reasons such as the lens of input equipment or sensor elements, the check image concentration that can be observed the image section of word or line is different.Under these circumstances, by the concentration correction process of blurred portions image, make by the fuzzy thickness caused of image color, word or line unified, thereby, it is possible to check out the difference of word or line exactly.After having carried out image rectification through such operation, compare inspection, thereby, it is possible to carry out offline image inspection accurately or consecutive image inspection.

Factorization algorithm is carried out to the image of printed patterns face (areaofprintedimage: print image zone), by the image surface colour examining (colormeasurementofimagearea: the color measuring of image-region) of matrix part (unit) unit, detect the difference of the gray scale of the color of two images carrying out checking, for above situation, there are two methods.In first method, pattern entirety is such as divided into each rectangular unit of 10mm, in order to remove, colour examining is carried out exactly on the impact of the adjacent unit of color periphery, with the center in each cell mesh region after segmentation for benchmark, according to the area occupation ratio set (such as, 60%), more split to refinement in each cell mesh region, carry out colour examining.Such as, according to the reading aperture size unit of about 1mm ~ 3mm (can freely set) that can be identified as color, the value of chromatism in cell mesh region is calculated.Now, can according to each aperture in cell mesh region, L*a*b* value is converted to from the rgb value calculated, the aberration L*a*b* value of the aperture size unit in the region of the unit after whole Factorization algorithm being added up to gather is divided by aperture quantity, average, calculate CMYK%, carry out color evaluation.

In addition, in second method, such as, observe monitor picture, while the spot area about utilizing positioning equipment to select 1mm ~ 3mm angle, colour examining is carried out to any specific position in pattern plane.Such as, in this case, while observe monitor picture, while for the pattern part in advance as middle tone and patch (site 100%) portion, to close to grey portion, the colour of skin, monochrome (C, M, Y, K) or the plain net portion of the color of the part of secondary colors (R, G, B), gray scale portion or drafting department each color carry out colour examining, calculate the difference value of benchmark image and check image, automatic analysis is carried out to the difference of gradation of image universe, thus, calculates the corrected value to each gray scale.

Use any one in above-mentioned two methods, use to compare tone (tonalityofthecolor) and analyze and the result that obtains, the bearing calibration of gray scale is calculated according to the difference of the gray scale of integral image, therefore, automatically can correct the color reproduction of identical operation, word can be eliminated and check mistake.When there is larger difference in gray-scale rendition in the area of the pattern such as photo, illustration, figure supposed in image and character area or when the concentration of gray correction or the difference direction of tone contrary, correcting area can be divided into independent, carry out different concentration or the correction of tone.On the other hand, when carrying out colour of solution, needing to detect tonal difference, therefore, the image before the correction carrying out concentration gray scale or tone being compared, each other thereby, it is possible to guarantee colour of solution precision.

When carrying out the self-verifying of " judging that whether a slice identical image compared is identical with the check image of carrying out typesetting in multiaspect layout mode " with a slice image section (simultaneously) for benchmark image, the interim image calling benchmark image from storer, in the mode of each one side (singleimage), continuously picture registration and audit by comparison are carried out to the image carrying out typesetting in multiaspect layout mode.In addition, when by when carrying out the image construction of nested (embedding) multiaspect (stepandrepeat) layout, equally, extracted by the separation of the image being embedded with an image of benchmark image, the interim image calling benchmark image from storer, at each same position place of the multiaspect layout image of check image, carry out picture registration and audit by comparison continuously.

Now, if benchmark image and check image towards with vary in size, then in the stage overlapping process, carry out image rotation, the process of adjustment size, in the mode of each one side, carry out whole picture registrations continuously successively.When the difference towards, magnification and picture position of check image is clear and definite, in advance benchmark image or check image are provided to the parameter instruction towards (sense of rotation or angle) and Scalable rate (%) of the unique point of the image overlapped, displacement and image, carry out picture registration and audit by comparison according to the order of each image of multiaspect layout.When clear and definite image characteristic point is more than 2, this position can be specified overlap.Certainly, also can carry out the extraction of automated characterization point to these picture registrations, automatically carry out whole operation.In addition, make a described image (singleimage) and the alignment of multiaspect (stepandrepeat) image, object images is fitted, primary image is set to multiaspect image, carries out picture registration to check with the multiaspect image of check image.

In addition, there is following method: in a galley, the multiple different printing operations being referred to as joint group (gangjob) are aimed at, carries out multiaspect layout, by the galley write image of laser to printing, print.The method is disposable carries out multiple presswork and the paper cut the waste in vain remaining, achieves time and cost cutting.

In printed article Inspection when the layout of joint group multiaspect (following, when be called simple " joint group "), often form a version of carrying out printing by the operation of multiple client.Therefore, it is desirable that, according to the version unit of joint group, the image checked is carried out in input, is saved in a file.In addition, owing to sometimes there is the arrangement of the single page of entanglement in a version, therefore, after individually image input being carried out to respective printed data, the configuration sequence of benchmark image and check image is corresponded to identical, automatically or by positioning equipment, the image configurations of being undertaken checking is moved, continuously and side by side carry out picture registration and audit by comparison process.In joint group image inspection, benchmark image also becomes a check image by arranging identical arrangement with joint group, thus, also can be applied to the inline inspection in such as printing.

As mentioned above, in the multiaspect layout of the multiple operations based on joint group, need the benchmark image of multiple operation and carry out one side for each operation of multiple operation further and to fold or the check image of multiaspect layout checks.Such as, 15 kinds of operations of card printing thing, respectively as 15 benchmark images, on the other hand, for each operation in 15 each operations, carry out multiaspect layout to same operation, and the image amounting to 15 kinds is 40 by joint group.In this case, the check image corresponding with one of multiple benchmark image is automatically retrieved and has been carried out the image of one or more surfaces layout, carries out overlapping and checking.In addition, the check image corresponding with one of subsequent reference image retrieves continuously has automatically carried out the image of one or more surfaces layout, carries out overlapping and checking, then repeatedly carries out this action, until carried out the inspection of last benchmark image and check image.In addition, by Inspection information list described later, job instruction is indicated in advance, thus, even if when to different operations is carried out multiaspect layout to print with each client, appointments such as checking threshold value also easily can be changed.In addition, independent check result report can be exported to each client, transmit check result to suitable responsible official.

In addition, also can carry out multiaspect layout to said reference image, become the arrangement identical with check image, carry out picture registration and inspection.In addition, the check image after corresponding benchmark image and one or more surfaces layout is checked with above-mentioned joint group in order to automatically retrieve, and carry out graphical arrangement, can for each the independent flow diagram picture as benchmark image, obtain single page image or organize the positional information that version becomes each image of multiaspect, thus, automatically specify and check position, be set to multiaspect layout image, carry out picture registration and inspection.

As mentioned above, in the image testing device 10 of the 1st embodiment, such as, even if examinant no matter for the word of foreign language or figure, even when examinant can not understand its content, also benchmark image can be set to and check image compares, detect difference, therefore, having can be easy and carry out exactly checking such convenience.In addition, also can pass through the means such as OCR (opticalcharacterrecognition: optical character identification) from image, extract text, carry out text data inspection each other.

[the 2nd embodiment]

Figure 11 is the figure for illustration of the image inspection in the image testing device of the 2nd embodiment of the present invention.The image testing device of the 2nd embodiment can be realized by the 26S Proteasome Structure and Function identical with the image testing device 10 of the 1st embodiment.In the 2nd embodiment, image inspection as follows can be carried out.

2nd embodiment relates to following situation: although be transfused to and carry out the benchmark image of the 1st view data and the 2nd view data shown and check image is identical content on monitor picture, subregion is made up of different typesettings.In addition, in each page image corresponding with the multi-page pictures after page group version, or when comparing inspection with described joint group image, use identical technology to check.Below, the explanation of subregion image is carried out.

Make to be made up of different typesettings but the subregion image 71 ~ 73 of the check image corresponding with the subregion image of benchmark image is associated with each other, carry out picture registration process.Such as, the order CMM1 of image inspection is set to M1 subregion image, CMM2 is set to M2 subregion image, CMMn is set to Mn subregion image and associates, thus associating.And then, for each the subregion image associated, be set to the 1st view data and the 2nd view data, carry out picture registration process, and be handled as follows.

As mentioned above, in inspection in content element when identical but the benchmark image that typesetting is different and check image, at the word to the correspondence in the 1st view data and the 2nd view data, the various subregions such as photo or figure image 71, 72, when the content element of 73 compares each other, in order to carry out picture registration, such as, positioning equipment is utilized to cross the region of carrying out each several part that correspondence compares in benchmark image, automatically image retrieval is carried out to the area part of the correspondence of check image, extract the region of copying benchmark image and surround frame, the subregion of the correspondence of check image is specified with encirclement frame, associate.Now, by positioning equipment, cross its various subregion with frame, in order to associate, utilize branch's numbering name of subregion to associate with job name, correspondence is carried out to each subregion typesetting, with frame round image check.In addition, can together with check image, the subregional positional information of appendix.About check result, freely picture display can be carried out to any one in each benchmark image and check image.

As mentioned above, when carrying out joint group image inspection, preparation carries out multiple flow diagram pictures of joint group as benchmark image.In addition, multiple check image, for each operation, carries out one side (one side) or multiaspect layout to same flow diagram picture.Therefore, by Inspection information list 49, for each the independent flow diagram picture as benchmark image, obtain carried out joint group single page image or multiaspect layout image positional information separately as check image, based on this information, be made order according to Inspection information list 49.Or, by carrying out the benchmark image of this whole operation and associating between check image, thereby, it is possible to automatically carry out picture registration and inspection.In addition, or, can be undertaken as instruction of issuing orders by Inspection information list 49: specify the benchmark image of whole operation and word, the picture material such as pattern or figure of check image; The repetition number of the check image of instruction multiaspect layout; And automatically retrieve instruction, thus, automatically carry out associating of benchmark image and check image, automatically performed the picture registration between whole benchmark image of joint group and check image and inspection.In addition, can in the order of Inspection information list 49, input comprises the indication information of the full content needed for inspection of inspection area or inspection precision.

Employ the Inspection information list 49 formed like this, the basic inspection shown in Figure 13 and to revise a series of flow processs of operation as follows.First, (1) Inspection information list 49 is carried out to the input (step S100) of job information or operation directive command.About inputted job information, according to from special printing management system or MIS (ManagementInformationSystem: operation information management system) work data and carry out the electronic bill of operation instruction, select the picture of the PC of Inspection, obtain the information needed for Inspection information list 49.Acquired information such as have business responsible official, Customer Information (exabyte, be responsible for name, deployment or post), information that order operation is relevant (job name, order day, delivery time target date, enter original text data, enter original text thing (color model etc.), complete size, black number of color, printing number of packages, the kind of paper, number of pages, surface working, method for folding, method of modifying) etc. information.Inspection personnel selection examiner name, Inspection name.

Next, select time check data, check position, Inspection operation, and, select (2) benchmark image/check image (step S102), select (3) to check instruction (step S104), actually to check.The selection of benchmark image/check image is such as carried out in the following way: select to have carried out the image of digital input by camera or scanner to PDF or printed article, and be saved in the image file of Inspection information list 49.In addition, inspection instruction in, comprise intra-company or and client between control information.

In inspection instruction, prepare other layer for determining the inspection area checking thing or inspection numerical data, in inspection area, according to operation directive command, chain is connected to inspection directive command.In addition, in inspection instruction, be written with above-mentioned inspection directive command and check instruction remarks.When checking, by audit by comparison software, picture registration is carried out to the benchmark image of (2) selected and check image, on this basis, utilize by the threshold value of the inspection instruction of (3) by writing in other layer, the inspection directive command according to determining the height checking precision compares inspection.In addition, can positioning equipment be used, specify the scope of examination manually or automatically.

Like this, after having carried out inspection, (4) outgoing inspection report the test (step S106).In check result report, be divided into the layer of separating with check image, utilize the indicia framing of the difference between benchmark image and check image representing (2) to show check result.In within it holding, except Inspection information, also record time check data, inspection deployment, examiner, the numbering determining the inspection position of Differential Detection position and inspection error location, Differential Detection position and check wrong content, inspection area, threshold value and check result etc.

In check result report, when checking as NG, (5) export and revise instruction (step S108).Revise instruction and comprise (a) internal calibrations amendment instruction and (b) client calibration modifications/change instruction.Suppose, when recording inspection mistake (checking defective print) in check result report, according to the inspection instruction of (3) inspection instruction hurdle, confirm word or the color of inspection area, if there is bad position, in the correction instruction hurdle that the check result of (4) is reported or the layer different from check image, revise position by recording for the directive command of text or automatic calibration and revise content (dot gains correcting value, the correcting value of the site % of the gray correction method of pattern or each version of CMYK, the diff of L*a*b*, or aberration Δ E etc.), carry out the instruction that the CTP of the Yin Qian department of front operation is exported automatically or manually.

In addition, start and carry out the DTP application software cooperated and the plug-in card program developed in addition with the content that above-mentioned correction indicates, according to the correction directive command of Inspection information list 49, carry out manually and auto modification.On the other hand, about the correction that can not automatically process, according to the content revising instruction text, carry out manual correction by positioning equipment.

And then, utilize image testing device, picture registration/audit by comparison is carried out to benchmark image and the revised check image of automatic/hand of (2) before checking, if two images do not have difference, then exports (6) correction conclude report (step S110).Such as, when there is uncorrected part in a part, turn back to step S108, in automatic mark to correction instruction, revise.

When revising, exporting (7) and checking correction history (daily record) (step S112).Revise in history in inspection, according to operation directive command, automatically will when, in which operation, have been undertaken checking several times by whom or revised operation and whether operation completes or whether school is complete as daily record, additional links or write in the file or other storage file of Inspection information list 49.In addition, export (8) client to propose with report (step S114).Propose, with in report, to reflect the information of the part in the check result report of final (4), and propose to client client.Propose, with when being reported as " responsibility check and correction is complete "/NG, in being recorded (5) correction instruction of step S108, again to start to revise operation when client.

Finally, according to operation directive command, export (9) job scheduling control report (step S116).By job scheduling control report, according to the confirmation of inspection image folder, be automatically made the progress control table till correction of a final proof is played from first revisal to check image.These information are passed to progress control system etc., for confirming what degree the flow chart of each operation is accomplished to.

In addition, by being delivered in business management system or MIS, thus, according to the color correct number of times of word correction number of times or image, in addition, cut down effect etc. according to the color adjustment number of times of printing, printing time, cost management, electric power, the kind of use ink or carbon dioxide, can, in design department, Yin Qian department, printing workshop department, make utilization effect improved visual.In addition, after school is complete, be divided into by operation slip up the image caused discrepancy and by printing the person of placing an order cause enter the correction after original text change, be any according to the reason of operating cost, carry out distribution absorption of costs being still assigned to business to workshop, and pass to MIS etc.

Next, to according to the important inspection indicating means comprised in Inspection information list 49 and Inspection, the mechanism and the effect thereof that export miscellaneous service control report are described.First, (3) are checked that instruction is described.(3) inspection instruction inspection instruction be following instruction: have recorded client and think the significant points that the word of particular importance maybe should carry out image etc. inspection and confirms, and instruction the operating personnel of each operation to the important threshold value confirming the rank of point and inspection precision etc. completed when situation (automatically) checks or when confirming check result.Specifically, indicate as follows.

Be enabled in the PC11 and audit by comparison software that use in image review systems or image testing device 10, picture registration is carried out to the 1st view data 31 and the 2nd view data 32, compares inspection by the inspection order be recorded in the layer different from check image such as threshold values.In addition, also can use positioning equipment, manually carry out the appointment of the scope of examination.

About check result, as shown in figure 15, such as, in the back cover sheet 70 of the inspection appraisal report reported in the check result of (4), shown by the indicia framing 34 in the discrepancy display image of check result discrepancy display view data 33, and the difference of Show Color is carried out with the frame 71 of different colors, wherein, institute's check result discrepancy display view data 33 is the results of carrying out picture registration and difference inspection to the 1st view data 31 and the 2nd view data 32 and generating.In addition, check result can in the such as back cover sheet of Inspection information list 49, display in the 2nd page or check result report the 2nd page etc.

In addition, as shown in figure 16, such as, in the surperficial page 72 of check result report, record the threshold value according to each inspection area and the discrepancy number of the word that checks out and color and each check threshold value.In addition, about the discrepancy of color, according to being described the L*a*b* value after file transform from RGB, aberration (Δ E) or tonal difference is shown as in addition.In addition, so-called tonal difference to refer to from L*a*b* value divided by the Δ a after L* value and Δ b value at this, in the implication that term and aberration are distinguished, have employed the performance that tonal difference is such.These also can in the such as surperficial page of Inspection information list 49, display in the 1st page or check result report the 1st page etc.

In addition, about Inspection information list 49, the words of single page export by each single page, and the words of group version export by group version work unit.But, when by group version assignment partition be single page check, be set to single page unit or group version page, export (issue) Inspection information list 49.

Next, the report of (4) check result is described.As shown in figure 14, in the check result report of (4), the following information obtained after carrying out image inspection is comprised.

(main contents of check result report)

(a) Inspection display image and wrong display area: the display image showing the discrepancy of mistake etc.,

B () quality of colour checks curve map and numerical value color evaluation: show quality of colour check result,

(c) individual inspiration result: the image inspection result showing independent discrepancy display area,

(d) Integrated Checkout result: show comprehensive image inspection result (good no judgement or average color difference etc.),

(e) message: the remarks showing perhaps modification method etc. in the correction to check result,

In addition, show about these pictures, by the operation of image testing device 10, make various check image switch to the display of wrong display frame or message area.

As shown in figure 14, check result report 49A is a part for Inspection information list 49, its content shows as illustrated in the display frame of display 12, and the output for printing or data output can be carried out as shown in Figure 15 and Figure 16 like that, can also show together with the report of the various evaluations in the check result of image inspection representing image testing device 10.This check result report 49A according to the prior setting value of examiner automatically or inputted by the operation of examiner, such as, is made according to the inspection designation data of preserving in HDD29 or former inspection correction historical data automatically.

To this, in the data in DTP makes or proof, for the data of the color scheme of previous first revisal, again school or client or the PDF that brought by client etc., need to be confirmed whether to revise as indicated, therefore, so far, need visual identification.In order to make their robotizations by equipment inspection, except the input for independent benchmark image and check image being set to a pair or make file preservation, picture registration, inspection, report carry out except processed continuously batch facility, also need to carry out the inspection instruction of (3) of recording as the inspection order recording inspection area, content and inspection threshold value.

Therefore, such as, after job name, additional odd-numbered carries out job name registration to benchmark image, and with the filename of the mode additional input original copy or data that become even-numbered, carries out job name registration to check image.In addition, be set to following mechanism: by arranging Automatic continuous batch program in advance, only according to job name, page number and reference number of a document, paired image is made automatically to the data be input in same file folder, carry out picture registration, according to the inspection instruction of (3), automatically perform whole Inspections.In addition, check result is as a part for Inspection information list 49, and additional numbers in the version of filename (setting benchmark image as A image, if check image is the filename of B image etc.) and checks sequence, carries out printout and data are preserved.

That is, in be made Inspection information list 49, show: the content-data representing the Inspection unit of the information relevant to Inspection; Indicia framing etc. is utilized to represent the image of the discrepancy display image of discrepancy display area etc.; Represent that the quality of colour of quality of colour check result checks curve map; The numerical value color evaluation of image inspection result is represented with the numerical value of L*a*b* value or aberration Δ E; Represent the Integrated Checkout result of comprehensive image inspection result; And represent the individual inspiration result etc. of image inspection result of independent discrepancy display area.In addition, in the display frame demonstrating check result report 49A, various display switching push button, image reading button can be shown simultaneously and point to the connection instruction button etc. of the server of signal conditioning package 110 described later or the audio/video contact information systems (multimedia information system) of above-mentioned (10).

Such as, whether correctly revise about revising position in DTP flow chart, the mark making the cue mark on the marker at expression correction position and caused by inspection shows with overlapping, at the position of not implementing to revise, do not exist by checking the mark caused, therefore, easily judge, OK is shown when completing and all revising, if there is still uncorrected position, at least one place, then show NG and/or show and do not revise position, and be recorded in check result report 49A.

In the inspection of the character area of printed article, when showing checkout discrepancy point according to the discrepancy of the image checking dust, stains or damage etc., catch the connected size of pixel as discrepancy block, block larger for the total pixel count of block is judged as the difference of word.On the other hand, if there is the mark at the amendment correction position of word, then in report, record correction complete, if there is no the mark at the amendment correction position of word, then capture as mistake, in report, record NG.

Be wire about the pixel count of discrepancy or discrepancy block and be the discrepancy below number pixel or can by the dust of the visual smallest point fully confirmed on printed article, it is the size about the block of 5 pixels when the image of the resolution of 200dpi, more than this, such as more than the block of 20 pixels, the block that overall concentration is more shallow counts as dust, and carries out report record to the quantity of dust.In addition, about dust/damage/fuzzy/be infected with the discrepancys such as stains, indicated by different marker colors, easily can carry out correction operation.

In addition, in check result report 49A, not only character image can be used, Δ E can also use numerical value (such as, 1.3,2.0,3.5,4.0,5.9 etc.) or evaluate with symbol (such as, AAA, AA, A, B, C, D etc.) hierarchically show, thus adopt and be usually considered to hold wield labeling method (such as, OK/NG or zero/× etc.).In addition, using a part for this report result as the proposition report being supplied to client as described above, (8) client can be set to and propose with report.

Finally, reflect the information of " content from the presswork of bar code subsidiary in MIS or presswork bill etc. " and " from the printing instruction of client or quality management person with based on the amendment correction instruction content corrected ", and then, record the result of determination checking responsible official.In Inspection information list 49, integrate all or part of of the information of following (KTA-A) ~ (KTA-KI), the check result in this operation have input OK, terminate the operation to this operation.

But, finally, obtain printing place an order responsible official or person liable license before, even if check result OK, the operation of flow chart does not also complete, and therefore, can be divided into and check and to terminate and operation completes, report in 49A being described below information in check result.

(A) examiner, Inspection, check number of times (1,2,3 ..., n time check),

(B) date-time, checks position, Inspection operation, checks number of times, checks threshold value, checks printing surface image,

(C) the existing supervision time, this supervision time,

(D) instruction at correction position of each examination scope frame and the judgement of OK/NG,

(E) volume check of the detection of wrongly written character and dust, and dust

(F) color box of the aberration (values of Δ E etc.) utilizing numerical value preset with expression, shows the color evaluation (difference of hue difference ah E and CMYK%) at the important colour examining position of being specified by client,

(G) situation (OK/NG) of check result.

Next, revise instruction to (5) to be described.When the correction instruction of display (5) in the individual inspiration result display field in the check result report 49A shown in the Figure 14 comprised in the Inspection information list 49 shown in Figure 12 time, demonstrate the position becoming the mistake (discrepancy) revised the position of omitting, the dust detecting check image or be called stains because of this inspection.

Revise instruction indicate to is represented by indicia framing etc. discrepancy display image in discrepancy display area carry out what kind of revise ability passable, the responsible official of all departments is easily revised according to Inspection information list 49.In addition, in correction instruction, can comprise and indicate according to the correction of correspondence, the actual CPU21 of image testing device 10 that makes carries out the correction order revised automatically.

In addition, in check result report 49A, image illustrates by indicia framing and color the position of the difference of more than the threshold value that there is setting, and, such as, about being difficult to the part automatically judging difference, by checking that whether responsible official carries out revising the word at position by the judgement correctly revised, if OK, then carry out admitting to confirm request in the indicia framing of this part.Color differentiation under other color can be used to carry out this situation.

In addition, having constructed following mechanism: when needing the judgement judging authority person, directly or by the communication means such as audio/video contact information systems or E mail, having sent check result report 49A, and receiving feedback at once.About the position confirmed the instruction that the difference of color is revised, image marks measuring point and measures numbering, CMYK% is shown in other picture, when being greater than pre-determined difference, utilizing the Show Color at a glance easily found out to represent and carrying out preset aberration according to the size of difference.

In the appointment based on the amendment correction position corrected, the layer that can be made together with image or to separate with image, in the enterprising row labels of layer, also can by the mode making the information of record in advance become transparent overlap, even if overlapped in display image in correction position and correction content, also indication information can be read.Thereby, it is possible to whether the position free of errors determined for carrying out revising correctly is revised.When carrying out word correction, finally visually can confirm word, also can select the indicia framing on layer, make it possible to judge fast the result that amendment is revised, thus in check result report 49A, reflect OK or NG at once.

In addition, such as, in DTP flow chart, whether correction is implemented about correction position, cue mark on the marker at expression correction position and the mark caused by inspection can show with overlapping, at the position of not implementing to revise, owing to not existing by checking the mark caused, thus easily judge to obtain.In addition, about the correction content of word, can show in prompting frame by clicking mark, therefore, it is possible to whether carry out the judgement of correct correction at once.OK is set in the completed situation of whole corrections, if there is the position that at least one place is not revised, then be set to NG, and carry out preserving and record as check result report 49A and progress control data, or, as the information representing progress control, the display frame of display 12 shows.And then, send whole job history to PC, thus be reflected as progress control data.

In printing process, comparing finally organizing the complete paper of edition data or school with the printed article of sampling out, thus, the discrepancy numbers such as the difference of the image produced in examination India and China, dust or stains being recorded in check result report 49A.In addition, utilize concentration or the tone of image, will detect that the part mark of difference is on the image 79 reduced by printed article in the left side of Figure 14, and be recorded in check result report 49A.Information is converted into and revises indication information order together with these remarks needing the position revised, and becomes the correction instruction of next correcting process of instruction (5), automatically on monitor picture, can also carry out feature display to correction position.

About correction instruction, such as image such as display such as the discrepancy of JPEG, tiff image etc. can be converted to PDF form and be written to reports in the file of the layer that 49A is different from check result, can also by checking the number or zero shape circle and charge to responsible name etc., carry out correcting or the confirmation/unconfirmed of instruction of correction etc.

In addition, about the various data comprised in Inspection information list 49, such as be saved in the server of the signal conditioning package in image review systems described later, by using intra-company LAN, WAN, leased line network, in the front of the operator of printing machine, confirm at once, thus can be used in the color adjustment of printing machine, or, if directly construct out the interface with printing machine, then directly can control the black key of printing machine.

But, in this case, by being made black family curve in advance, in this black family curve, the black scale arranged on the printer illustrates the relation between dial plate (dial) value of the opening and closing amount of Mo Jian and the pattern area rate of printed article, thereby, it is possible to calculate correcting value out of ink more accurately.

In addition, about the color correct instruction having carried out the image after checking, the image correction function that carries in DTP application software or the RIP that applies in a flexible way is started carrying out color correct instruction.In this case, observe the image shown in the PC monitor of client or the monitor of portable information terminal, carry out by the following method on one side.

By curvature correction function, numerical value (CMYK%) is utilized to carry out the correction of assignment curve or middle tone,

From the image shown with different brightness, select optimum image,

The color correct instruments such as dropper function are used directly to revise,

From the image of shown various grey balances, select optimum image.

[the 4th embodiment]

Figure 17 is the figure of the image review systems that the 4th embodiment of the present invention is shown, Figure 18 is the encryption of the view data that checks of the carrying out illustrated in image review systems etc. and the figure of distributed and saved, Figure 19 is the figure of the recovery of the view data illustrating that the carrying out of encryption in image review systems and distributed and saved checks etc., and Figure 20 is the printing work flow figure in image review systems.In the image review systems 100 of the 4th embodiment, via network 101, the multiple signal conditioning packages 110 comprising personal computer or workstation etc. are connected for communicating each other with multiple portable information terminals 120 of portable phone, smart mobile phone, notebook, flat board etc.In addition, signal conditioning package 110 or portable information terminal 120 have phone (call function) or video receiving function is used as audio/video contact information systems, can construct multimedia communications system.

Each signal conditioning package 110 has above-mentioned image testing device 10 respectively, and such as, at least one signal conditioning package 110 has the function as server, and out of Memory treating apparatus 110 and portable information terminal 120 have the function as client.According to the image review systems 100 formed like this, via network 101, our company of printing firm, printing workshop, agency or client etc. are in each signal conditioning package 110 arranging diverse location respectively or portable information terminal 120, such as, described multimedia communications system can be utilized to confirm the image inspection result of benchmark image and check image.

As mentioned above, in order to more rapidly and construct out the workflow of printing easily more accurately, need to realize digital network flow process, this digital network flow process is used for by the information communication unit of the safety of network line of applying in a flexible way to greatest extent, carry out from printed article etc. from a series of quality management till the inspection corrected when playing delivery.Therefore, whenever carrying out order operation, the Inspection information list 49 of numeral of applying in a flexible way.

In the 9th function of Inspection information list 49, comprise: the operation directive command using Inspection information list 49, pass through network, the view data and the Inspection information list 49 that carry out inspection are safely (following, as required, be called " inspection view data etc. ") transmitting-receiving.In addition, the data of receiving and dispatching are that carry out checking or before checking descriptive language, the document data comprising the view data of photo or illustration etc. or the check image data etc. such as text data, HTML (HyperTextMarkupLanguage: HTML (Hypertext Markup Language)) data, XML (eXtensibleMarkupLanguage: extend markup language) data.

In addition, in order to receive and dispatch inspection view data etc. safely, as shown in Figure 18, Figure 19, for each document data or for each image checked inspection view data etc., copy according to the quantity of the security can guaranteeing information recovery, be divided into character string, photo or pattern etc., be encrypted.In addition, when segmenting the data of inspection view data etc., every a slice subdivided data is given for using random number to recover the recovery label of image from subdivided data, and subdivided data is kept in independent server or distributed and saved in multiple server.In addition, in order to improve security further, it is desirable that, make several n of server be greater than copy several m, make to utilize the information from a server to restore data.In addition, document data or inspection view data etc. also can not be divided into character string, photo or pattern etc.In addition, the encryption of image can be carried out before or after duplicating image, or carried out before it is split or after segmentation.In addition, when using public-key with private key, private key is sent in addition to the other side side.

At receiver side, receive from the server preserved, for each image carrying out checking or once, use random number, utilize and restore label to be subdivided and encrypted document data or inspection view data etc. are restored, and then, password is decrypted, based on document data or inspection view data etc. carry out operation management.In addition, so-called server refers to the server of independently server or cloud mode herein, freely can carry out distributed and saved by mix server, carries out the data protection countermeasure of attacking away from the external information such as server failure or cyberterrorism, thus applies in a flexible way.In addition, by indicating setting program action in advance, utilize single job automatically to carry out copying, encrypt, segment, give employ random number recovery code until the instruction of distributed and saved.In addition, the recovery of the calling of its contrary preservation file, partition data, the deciphering of random number that accesses to your password also automatically are carried out by single job.

As an example, first, according to the unit of each character string, photo or pattern, to the plural Image Segmentation Using checked, according to segmentation unit, image is encrypted, or according to not having situation about splitting to be encrypted image, and then, be rectangular by the image subdivision after encryption, give the recovery code of random number employed, this recovery code is used for carrying out image restoration to all images fragment of the size of data being subdivided into about 1KB.And then, disposable or dividually above-mentioned segmentation is sent to necessary server or client rs PC.

At receiver side, for the fragment figure picture after each segmentation, from preserved independent or multiple server or client rs PC, call the multiple segmentation files forming and independently check corresponding image, be aggregated into and be integrated in the segmentation file of.Utilize the recovery code employing random number, image restoration is carried out to the fragment figure picture that this segmentation is set a file, to the decrypt data after each encryption, be integrated into an image that will carry out checking, and be set to can visual identification, thus, carry out checking the distributed and saved by view data etc., and carry out safe information management by information communication unit.

In addition, in the 10th function of Inspection information list 49, comprise: intra-company's rectifying inspection and and client between rectifying inspection in, use communication unit to carry out easily with the transmitting-receiving of benchmark image, check image and the discrepancy data checked and discrepancy correction order and the communication for the report contact talk for discrepancy position.That is, its basic function is the video communication of band audio-frequency function, the data communication carrying out the image checked, the communication of inspection order and the log information etc. of the situation of inspection, and carries out inspection contact by multimedia communication.As mentioned above, as the countermeasure that information leakage does not occur in this case, more preferably, the image of inspection is such as divided into the regions such as word photo or pattern as described above, and then, according to segmentation unit, be encrypted in addition, be sent to necessary server or client rs PC, at receiver side, there is the recovery system that can be decrypted.In addition, the information for relevant Inspection information list 49 is carried out too.

Namely, as an example, image testing device 10 to the signal conditioning package 110 of certain position carries out image input, via network 101, the 1st generated view data 31, the 2nd view data 32 and Inspection information list 49 are sent to the image testing device 10 of the signal conditioning package 110 being positioned at other position.In the image testing device 10 of signal conditioning package 110 receiving the 1st view data 31 and the 2nd view data 32 of sending, carry out image inspection process, and then, the Inspection information list 49 comprising the data relevant with check result to these view data 31,32 is sent to signal conditioning package 110 that be positioned at other position, that have server capability.

In the signal conditioning package 110 receiving the Inspection information list 49 comprising relevant access code and inspection result data etc. in the check result of sending, out of Memory treating apparatus 110 or portable information terminal 120 pass through multimedia communications system, in mode of freely reading, share the Inspection information list 49 of the data relevant to check result etc.In multimedia communications system, except there is computer function, also there is phone, video, mail, inspection correction or revise the mutual transmission-receiving functions such as directive command, therefore, between transceiver terminal, extremely careful communication transmission can be carried out.

Like this, if apply in a flexible way the various information equipments connected by network 101 alone or in combination, then such as, from long-range signal conditioning package 110, via network 101, utilize and comprise the Inspection information list 49 indicating relevant data etc. to preserved check result and correction (correction), carry out the correction of printed data, or carry out image inspection or reexamine, or check result is informed to out of Memory treating apparatus 110, or while utilize video or audio frequency to obtain record, while obtain contact, thus, can prevent from transmitting error, easily can confirm progress msg according to control information, production efficiency and cost cutting effect etc.

In addition, by the Image Saving of the plural image and check result that will compare inspection as in the signal conditioning package 110 of server, thus, no matter wherein, all can carry out reading or again checking via network 101.Such as, the proof image as benchmark is there is in our company of printing firm, digitizing is carried out to it or preserves as database (DB), thus, examiner can via network 101, utilize the image testing device 10 in the signal conditioning package 110 at the scene at each printing workshop, the whole nation, image input or the image after checking are forwarded in check result view, in the signal conditioning package 110 at each printing workshop, utilize image testing device 10 individually, picture registration is carried out to the image of the printed article after image input, bad position is checked, thus, the rank that the discrepancy of the threshold value considered between each printing workshop is detected is consistent, thus the inspection can carried out under unified specification.In addition, also can send data etc. relevant to check result to client, thus can carry out from client to the access of signal conditioning package 110 with server capability.

In Inspection information list 49, by preserving date saved time of initial Inspection, Date Of Change time of file, Gu Keming, job name, text, data retrieval function based on thumbnail, thus, the data management of each client can be processed in real time, therefore, improve the efficiency of in-company data encasement operation, and, when carrying out the communication relevant with the instruction of the correction of typesetting, word or image etc. to client, instantaneously can provide required information, thus both sides can be made to advance operation efficiently.

In image review systems 100, in order to the scheduling features such as process management software or MIS of applying in a flexible way, monitor print result at once, from image testing device 10, the number completing position of the number of difference and the checkpoint at amendment correction position is counted, output report, and send online via network 101.Thus, make the confirmation at the amendment correction position between each signal conditioning package 110 and towards subsequent processing operation excessively become reliable.

In addition, color management department in image review systems 100 or operating department etc., numerical value can be utilized the color of the image of the result of the image inspection in printing or after printing to be confirmed as difference, therefore, it is possible to reduce the chance at the printing workshop that client goes on business long-range because (vertical Chi meeting い) is checked in printing.Thereby, it is possible to improve the operating efficiency of printing, reduce printing cost.

But, in this case, as image input device, it is most desired that, adopt following image input device: about the color filter of camera or scanner, do not use RGB, and use CIEXYZ color filter, thereby, it is possible to high precision utilizes L*a*b* value to carry out digitizing to image.Further, it is expected that standard deviation Δ E uneven in the colour examining precision of color, colour examining precision repeatedly, face is less than 0.1.In addition, the color management carrying out monitor, display and proof press is exactly also very important.

In addition, via network 101, in the image preserved from the signal conditioning package 110 with server capability, automatically retrieve and select and compare a benchmark image of inspection and the image of check object, be set to check image.Especially, DTP (DeskTopPublishing: the desktop printing) data of the printed article that the several years modify about carrying out chronically printing, if have invoked old image (falling back) mistakenly, then sometimes the data finally utilized are recorded in database, when automatically retrieving, do not call final page data, and be backwards to the image to correct mistakes etc.Therefore, by showing relevant approximate image all the time or show whether there is page data when retrieving simultaneously, the error fallen back is eliminated thus.It is desirable that, image review systems 100 has search engine, this search engine, in the change, correction of image file, is preserved and shows a series of change history, reliably carrying out required final image or the preparation of page data.

In addition, in the signal conditioning package 110 of our company of printing firm inside, construct database server (DB server), password is transmitted to client (person of placing an order), and the DB region providing client special in units of file, thereby, it is possible to be separated safely with the data of other client and utilize.In addition, in total data, from the stage entering original text, the code that Additional Customer is special in filename, and make it have and can not get data wrong and the mechanism being transmitted to other client, and, apply the encryption of inspection view data above-mentioned or described later etc., copying and finely divided specimens preserving, thereby, it is possible to carry out the DB management of the security function with height.

But, need to realize have sent the situation of data for not recognizing mistake thus making the third party watch the information leakage countermeasure of data etc.As this countermeasure, carrying out the data of data encryption by sending, resolving code or password being directly transferred to client or taking on department, guarantees the safety of data transmit-receive thus.

That is, applying in a flexible way in network 101 when comparing the benchmark image of inspection, the control information between check image and client or correcting image, there is not information leakage in (a).In addition, even if need to construct the server fail storing (b) PC of correspondence image, the memory storage of portable information terminal or cloud etc., the system also can restored at once.In order to realize the function of above-mentioned (a) and (b), such as, aforesaid following methods can be adopted.

Necessary total data is thought for reading in network 101 or the document sent, image, order paper and other litigant, these data are encrypted, and then, can the form of completely reversibility segment these data, copy and secret distributed and saved in a plurality of storage devices, even if make the fault or the cyber attack that there occurs information equipment, also can restore this data from out of Memory equipment.

Such as, even if break down in a part of position of PC or HDD or multiple position, also can restore out from the multiple HDD preserving the inspection view data that is replicated more etc.In addition, even if information flows out to outside, can not restore the data segmented, therefore can not reveal.Like this, in order to restore, such as, carry out each image segmenting sheet with rectangular and additionally in the overall sheet segment information that obtains restoring code.In addition, even if even restore out, if there is no the parsing key of encrypted information, then can not resolve.About this series of utilization operation, function can be added in the inspection instruction of (3) of above-mentioned Inspection information list 49.In addition, the segmentation mode of these data extensively applies to common information management neatly.

Next, about the utilization of image review systems 100 more specifically, enumerating the situation being applied to printing firm is example, illustrates as follows with reference to Figure 20.In addition, in fig. 20, parenthesized English character, represent the classification of each relation department, (A) represents client, and (B) represents outlet, and (C) represents our company, and (D) represents workshop.In addition, parenthesized numeral (1) ~ (14) represent operation.Therefore, in the following description, in the combination of parenthesized numeral and parenthesized English, only utilize respectively except the numeral of the numeral of removing parenthesis or parenthesized numeral is to represent the operation of flow process, be described.

First, benchmark image and model printout are taken to the outlet of agency etc. by client (client) (1-A).In outlet, according to benchmark image and model printout, (1-B) have passed through being made of order bill, comprise being made of the Inspection information list 49 of the content of Customer Information or operation, check instruction be made after, after being encrypted from (2-B) outlet, be sent to the operating management portion of our company of (2-C) printing firm, wherein, described inspection instruction indicates inspection area and the precision prescribed of benchmark (substantially) threshold value checked, important word, photo and figure etc.In the operating management portion of our company of (2-C) printing firm, the order bill data sent from certain agency, the color model printout data from client and the view data as its source data or PDF data etc. are encrypted, be sent to our company, request design portion carries out design based on these data and DTP operation (3-C).

In (3-C) design portion receiving request, design and DTP operation is carried out based on the PDF data received, with reference to color model printout data, carry out correction and the making of various image, in addition, generate the DTP data of the typesetting design having carried out text etc., together with these DTP data, be made to the first revisal data before the anterior request print of (C-3) print.And then, print in front portion at (3-C), according to typesetting/group version, RIP process is carried out to DTP data, such as, except 1 bit image data, be made 8 bit correction print datas needed for colour of solution or first revisal PDF data, compare inspection with model printout.When checking, using the inspection instruction from agency's request, to determining the baseline threshold of Basic examination precision or setting for the precision prescribed of inspection area, thus, carrying out the inspection corresponding with the requirement of client.
