Technical field
The present invention relates to effectively to be used in the technology of dot pattern reading system, this dot pattern reading system is exported the data corresponding with dot pattern by reading the medium face that has printed dot pattern.
Background technology
Well-known already by the technology that reads dot pattern output on the medium faces such as the being printed on paper data corresponding with this dot pattern.
About the permutation logic of this dot pattern, the inventor etc. have proposed several method.
In addition, by the printing technology high precision int with dot pattern, the collocation point figure has become possibility to high-density on paper.
As the patent documentation of the motion of the reading system of this type of dot pattern, appearance design 2003-528387 communique (patent documentation 1) that Anoto AB company submits to etc. is arranged.In addition, as the leading technology of the dot pattern that uses among the present invention, the PCT/JP03/03162 (for simplicity, being referred to as GRID-1) and the PCT/JP03/16763 (for simplicity, being referred to as GRID-2) that have the present patent application people to propose.
Patent documentation 1: appearance design 2003-528387 communique
Summary of the invention
Yet, among the system that has used aforementioned patent document 1 described dot pattern and since all be with optical pickup device with dot pattern as image taking, identification point figure from this image, if thereby watch the medium face attentively, dot pattern is probably with the naked eye found out.
If dot pattern is in the state that can with the naked eye find out,, thereby there is the problem that lacks confidentiality then because the information that dot pattern is represented is easily resolved.
In addition, owing to the dot pattern naked eyes visually are present on the medium face, thereby there is infringement medium face problem attractive in appearance.
Want to avoid occurring this kind problem,, have printing cost height, the complicated problem of reading device though can consider to adopt the transparent specialty inks printing points figure that under infrared light or ultraviolet light, responds, and unrealistic.The mobile telephone terminal of the band camera function that is widely used especially in recent years also is not suitable for using the method for these optical filters.
The present invention In view of the foregoing puts forward just, and its problem provides a kind of technology, and it only improves a little to existing printing technology, can be simply and realize with the naked eye finding out dot pattern on the medium face, promptly so-called steady form point figure at an easy rate.
The point that constitutes aforementioned dot pattern can be used on the printing ink of the random color that responds in infrared ray or the ultraviolet wavelength zone, is arranged on the aforementioned medium face by printing treatment.
The said herein printing ink that responds in infrared ray or ultraviolet wavelength zone (reaction printing ink) can example illustrate the printing ink with characteristic that the light in infrared ray or ultraviolet wavelength zone responds, and more specifically, can carbon element printing ink be shown example.Under the situation of unresponsive printing ink in infrared ray or ultraviolet wavelength zone (non-reaction printing ink), if penetrate printing surface (medium face) with the illumination in the above-mentioned wavelength region may, with visible light, the light of above-mentioned printing ink face also is reflected, but under the situation of the printing ink that responds in infrared ray or ultraviolet wavelength zone, the light (reaction) on the printing ink face in absorption infrared ray or the ultraviolet wavelength zone does not produce the reverberation of printing surface.
As the printing ink that in IR wavelength or ultraviolet wavelength zone, responds (reaction printing ink), except that aforementioned carbon element printing ink, also can be not contain carbon element.For example as having the printing ink that absorbs infrared ray (reaction) characteristic with the molecular structure that does not contain carbon element, can list steady shape printing ink, its product is respectively for doing dense printing ink (trade (brand) name).
The point that constitutes aforementioned dot pattern can be used on the printing ink that responds in infrared ray or the ultraviolet wavelength zone, by printing treatment, uses with the color of the identical colour system of color of aforementioned medium face to be arranged on the aforementioned medium face.
By point being set at the color with the identical colour system of color of medium face (paper), can make the existence that naked eyes can't identification point, and can when reading dot pattern, utilize the reverberation that is radiated at the infrared light on the medium face effectively to discern the some part that forms with the ink printing that responds in IR wavelength or the ultraviolet wavelength zone.
The point that constitutes aforementioned dot pattern can be used on the ink printing that responds in the infrared spectral range and forms, and uses on the upper strata of this point with the color of the identical colour system of color of aforementioned medium face or the opaque ink of random color and forms common printed layer.
If adopt foregoing invention, because the upper strata of the dot pattern that the ink printing that responds in infrared ray or ultraviolet wavelength zone forms is used with the color of medium face and is formed common printed layer with the opaque ink of colour system or random color, thereby the dot pattern of lower floor becomes the state that can't with the naked eye see.But because IR wavelength is longer than aforementioned common printed layer, but thereby point of arrival figure, utilize its reverberation can optical identification to be in the dot pattern of lower floor.
Aforementionedly be made of one or more consistent with the color of image of this position or approximate colors, the printing ink that will respond in infrared ray or ultraviolet wavelength is with the printing that overlaps of concentric circles form,
In aforementioned point, make the diameter of the highest color of color range (the highest color range look) consistent with the diameter of the point of getting with the optics readout means reads;
The site amount of asking color is measured divided by the site of the highest color range look, obtained its square root, multiply by this square root by diameter and decide versicolor diameter the highest aforementioned color range look.
If this method of employing owing to pass through with concentric circles overlapping printing points, forms the look approximate with peripheral color, point is difficult to see clearly among sneaking into peripheral color, thereby is difficult to the naked eye identify a little.
To the common separately netrual colour color range zone of a major general part aforementioned C, M, Y value, generate when painting printed data,
Calculate the K composition (black composition) in the netrual colour color range zone except aforementioned, with can be in the visible light zone K printing ink (black) in the remaining netrual colour zone of optical identification on aforementioned medium face, print the dot pattern that forms according to the information generation of pre-light input.
If this method of employing, because the image of getting with the optics readout means reads by color separation processing can identify dot pattern, thereby needn't use complicated apparatus such as infrared radiation mechanism and optical filter to constitute, only use digital camera functionality additional on general digital camera and the mobile telephone terminal promptly to can read dot pattern.In addition, by when printing at least in advance except the common separately netrual colour color range zone (being similar to the zone of the color of K printing ink (black)) of a part of CMY value generate the printed data of painting, can prevent the error that reads of the dot pattern that causes because of K printing ink (black).
When reading from RGB data that original image obtains,
To each pixel of the original image that reads, seek the pixel of the additive value minimum of R value, G value, B value, this R value, G value, B value as revising a reference value, are deducted aforementioned correction a reference value from the rgb value of other pixel;
Get aforementioned maximum and the minimum of a value that subtracts the RGB data of each pixel after the calculation, obtain its mean value, obtaining can be according to the regulation region alpha of aforementioned mean value calculation,
The all values of judging RGB whether is all in aforementioned areas α;
When not in this zone, tonal gradation is made as white (100%),
In the time of in this zone, when aforementioned mean value is made as tonal gradation, width by compression aforementioned areas α when the tonal gradation of aforementioned mean value is high, relax the width of aforementioned areas α when aforementioned tonal gradation is low, can in the zone of the dot pattern of K printing ink (black) and common printed part, in the visible light zone, carry out optical identification.
There is a little characteristic when among as CMOS of optically read element etc., reading in general.This is that when influence power was very big, other color was attracted by it because of the same colour when color component deflection, or the inconsistency of device when making is also influential, and the result who for example reads often becomes the image of general green grass or young crops.If to the identification of this specific character image enforcement dot pattern, especially under the situation of claim 5 and 6 described color separation processing, because the cyan composition, the point of K printing ink (black) becomes and is difficult to read, and error often occurs reading.The technology of being revised when therefore, reading is the method for this claim 6 just.
That is, from the image that reads, retrieve the pixel of minimum as a result that adds of RGB.The pixel of the minimum as a result of adding of this kind RGB is point just.At this moment, in RGB occurring, have only under the higher situation of the value of B, be corrected for the strong image of cyan as can be known.Therefore, the pixel rgb value separately of the minimum as a result of adding of RGB as revising a reference value, is deducted this correction a reference value from other pixel.So the image that CMOS revises can revert to the state before revising.Then find out the result's that adds of RGB minimum of a value.This is the exploration to putting just.And with the darkest zone of this kind point discovery.
And, can revert to the original coloured image that the dot pattern of color seperation is adopted in the most suitable identification from other pixel if the RGB composition separately from this RGB Minimum Area deducts.
At revised image like this, get the mean value of the maximum and the minimum of a value of RGB data, when being the high value, the tonal gradation of this mean value passes through the width of compression aforementioned areas α, when aforementioned tonal gradation is low, widen the width of aforementioned areas α, can make the identification of dot pattern in the visible light zone of K printing ink (mass colour) become more easy.
Among each pixel, subtract when calculate handling aforementioned RGB composition, under the situation that becomes negative value, be made as 0 without exception.And the also available several pixels of the extraction of this RGB Minimum Area calculate the correction a reference value after repeatedly taking a sample.
To the common separately netrual colour color range zone of C, M, the Y value of major general part original image, generate when painting printed data,
Calculate the K composition (black content) in the netrual colour color range zone except aforementioned, with can be in the visible light zone K printing ink (black) in the remaining netrual colour zone of optical identification by make each the some dislocation definition information that forms original site with the regulation logic.
If adopt this method, by the site double as with the AM print process be the point of dot pattern can make perusal the time identification of printing net-point and point more difficult.
When color component is under the situation of C, M, Y, promptly become the netrual colour color range because one extracts common ground, K composition (black content), thereby be set at that to extract this K composition (black content) back double as be the dot pattern of site, but but this dot pattern also double as be the site of any one color of C, M except that aforementioned K composition (black content), Y.
C, M, any one color formation double as of Y, K with original image are the dot pattern of site, are used in the homochromy aforementioned a kind of color selecting of printing ink overlapping printing that responds in IR wavelength or the ultraviolet wavelength zone in aforementioned site.
Though this method is to have utilized the dot pattern of the site of the described AM print process of claim 7, but owing to be in the site, to use the printing ink overlapping printing points figure that responds in IR wavelength or the ultraviolet wavelength zone, thus can with site self size collocation point irrespectively.Therefore owing to do not need the CMY control that is used for color separation described in the claim 7, the size of site not the receptor site size about, thereby the size of point can be maintained fixed always, anti-stop read error.
In addition, point is overlapped to be printed in the site, because for the not multiple site of appending of printing image, thereby can not make the printing surface deepening.
Double as is that the color of the dot pattern of site can only be used any one color among C, M, Y, the K in same original copy, but also in the site of the different colours that can in same original copy, exist, corresponding with color separately, the homochromy printing ink that use responds in IR wavelength or ultraviolet wavelength zone, overlapping printing points figure.For example, if the C composition is more in certain zone in the original copy, in this zone, be a little then with C site double as, if the M composition is more in another zone, in this zone, be a little then with M site double as.
For example, under the situation that black crow and the people's who wears the yellow clothes clothes image are arranged in the picture, partly using the site double as of K composition (black content) black crow is a little, and the part of yellow clothes clothes is a little with the site double as of Y composition then.
In original image, will be set as shaded areas as the zone of the dot pattern that is used to discern, literal, sign or figure etc.;
With the zone beyond the aforementioned shaded areas of responseless printing ink in IR wavelength or the ultraviolet wavelength (hereinafter being referred to as " non-reaction printing ink ") printing;
Print aforementioned shaded areas by being used in the printing ink (hereinafter being referred to as " reaction printing ink ") that responds in IR wavelength or the ultraviolet wavelength zone, can when getting aforementioned medium face with aforementioned optics readout means reads, identify shaded areas.
If this method of employing because only masked areas is used in the ink printing that responds in IR wavelength or the ultraviolet wavelength zone, thereby can identify this masked areas in the optical pickup device of irradiation infrared light.In addition, because people's naked eyes can't be discerned the printing of using reaction printing ink and the printing of using non-reaction printing ink, thereby be difficult to the naked eye identify this masked areas.
At the color component of C, M, Y and the K of original image, form FM grazing point with the color dot random arrangement of shape;
Among the FM of aforementioned each colour content grazing point, use the locational FM grazing point of reaction printing ink (being used in the printing ink that responds in IR wavelength or the ultraviolet wavelength zone) the printing configuration of the color identical or approximate based on the point of dot pattern with the color component of original image;
With the aforementioned FM grazing point in addition of non-reaction oil ink print.
If adopt this method, be that FM with the point of the same shape of random arrangement covers dot pattern that the printing process printing is formed on the same colour system that used the printing ink that responds in IR wavelength or the ultraviolet wavelength zone in this FM grazing point or advancing colour.Because dot pattern and FM grazing point are same colour system or advancing colour, thereby with the naked eye are difficult to the identification point figure.In addition, because dot pattern is to form with the ink printing that responds in IR wavelength or the ultraviolet wavelength zone, thereby the optical identifying apparatus of available irradiation infrared light is discerned.

The specific embodiment
Embodiments of the present invention are described with reference to the accompanying drawings.
Each figure is the illustration of implementing mode of the present invention, and the part of the same label of mark is represented same object among the figure.
The principle of the dot pattern that uses among the present invention at first, is described.In the present invention, as the placement algorithm of dot pattern, two kinds of examples of inventor's invention are described.For simplicity, this is referred to as GRID1 and GRID2.
GRID1 is the PCT/JP03/03162 number application that the inventor proposes, and GRID-2 then is PCT/JP03/16763 number application.
(dot pattern explanation: GRID-1)
Figure 71 is the figure that illustrates of dot pattern of the present invention.Figure 72 then is the information point of dot pattern and the illustration enlarged drawing that shows of the bit of the data of definition thus.Figure 73 is the key diagram that expression is configured in the keying point information point at center.
Use the information I/O method of dot pattern of the present invention to constitute by the identification of the generation of dot pattern 1, this dot pattern 1 and according to the device of this dot pattern output information and program.Promptly, utilizing the camera of dot pattern camera head (also can be optical pickup device, the digital camera that is connected with PC, the camera function of the mobile telephone terminal of band camera) obtains after the view data, utilize the analysis program of installing in the mobile telephone terminal of reading device, PC or band camera, at first extract grid point, then there be not the original locational point of grid point to extract keying point 2 by beating, make it digitlization by information extraction point 3 then, extract the code that is transformed to behind the information area information digitalization.And make it to export the voice data that is associated with this yard and other information, program.In addition, information point 3 both can not be code but coordinate values, also can be with digitlizations such as voice data and other information.
The generation utilization point point coding generating algorithm of dot pattern 1 of the present invention is according to the regularly arranged keying point of predesignating 2, information point 3, grid point 4.At GRID-1, among, shown in Figure 71, the dot matrix of the dot pattern 1 of expression information is the grid point 4 of center configuration 5 * 5 with keying point 2, configuration information point 3 around the image point at the center that 4 grid point 4 center on.This dot matrix definable Any Digit information.Shown in the legend of Figure 71 in the section of dot pattern 1 (bold box) disposed 4 state side by side.But obviously, dot pattern 1 is not limited to 4 sections.
Can in a section, login 1 corresponding with it information and program, or in a plurality of sections, login 1 corresponding with it information and program.
If configuration grid point 4 in dot pattern 1, obtain the view data of this dot pattern 1 owing to can revise the distortion that causes by camera with camera, even thereby when obtaining the view data of dot pattern 1, also can correctly discern with the popular camera that the high camera lens of deformation rate has been installed.In addition, even the face that camera is favoured dot pattern 1 reads, also can correctly discern this dot pattern 1.
In addition,, be not limited thereto, also the grid point that constitutes the bight of dot matrix can be disposed as benchmark though keying point 2 is configured in the center of dot matrix.
In illustrated example, show 3 bits on 8 directions by being configured in, but be not limited thereto, also can show 4 bits by being configured in 16 directions, obviously can carry out numerous variations.
About 15～30% of distance interval between the preferably adjacent image point in the interval of the image point that information point 3 and 4 s' grid point 4 centers on.This is because if the distance between information point 3 and image point greater than this at interval, then each point easily is seen as big agglomerate, is difficult to find out dot pattern 1.In contrast, if the distance between information point 3 and image point is difficult to then assert that adjacent any image point is the information point that the center makes it to have direction vector less than this at interval.
For example, information point 3 is that the center is configured in the zone from I1 to I16 in the clockwise direction with keying point 2 shown in Figure 73, can show as 3 bits * 16=48 bit.
In dot matrix, have separately the independently information content, the sub-dot matrix that is not subjected to the out of Memory content influence also can be set.Figure 73 promptly is the diagram of this situation, and sub-dot matrix (I1, I2, I3, I4), (I5, I6, I7, I8), (I9, I10, I11, I12), (I13, I14, I15, the I16) that 4 information points constitute is separately the form that data (3 bits * 4=12 bit) are independently launched on information point.By this seed dot matrix being set, can sub-dot matrix being that unit easily carries out error-detecting described later.
The direction vector of information point 3 (direction of rotation) is preferably evenly stipulated every 30～90 degree.
Figure 74 is the illustration that the bit of data of information point and definition is thus represented, is another kind of mode.
In addition, if at information point 3, the image point that centers on from grid point 4 uses the long and short two kind, and direction vector is set at 8 directions, then can show 4 bits.At this moment, about 25～30% of the distance between the long preferably adjacent image point of a side, a side who lacks preferably about 15～20%.But the Center Gap of length information point 3 is more preferably greater than the diameter of these points.
Consider outward appearance by the information point 3 that 4 grid point 4 center on, preferably 1 point.But,, wish to set under the situation of more information amount,, can have a large amount of information with a plurality of bit performance information points 3 by giving each vector assignment 1 bit when paying no attention to outward appearance.For example, on the vector of concentrically ringed 8 directions, the information of information point that available 4 grid point 4 center on 3 performances 28 becomes 2128 with 16 information points of a dot matrix.
Figure 75 is the information point and the table of bits example of data of definition thus, and (a) 2 points have been disposed in expression, and (b) 4 points have been disposed in expression, and (c) 5 points have been disposed in expression.
Figure 76 is the variation of dot pattern, (a) is 6 information point layout types, (b) is 9 information point layout types, (c) is 12 information point layout types, (d) is the sketch of 36 information point layout types.
Figure 77 (a) and (b) are for the method for inspection message point tolerance is described, with the key diagram of STA representation information point I1 arranged side by side to information point I16.
In 13 bit of aforementioned 1 information point 3, make 1 bit have redundancy, handle the upper bit of the data that obtain from information point In and the next bit of the data that obtain from information point In+1 by homogeneity, be presented in information point 3 under the state on the medium faces such as printed article, different with the next bit that obtains from information point In+1 for the moment when the upper bit of the data that obtain from this information point In, be judged to be information point 3 and be not presented on the appropriate position.
In addition, Figure 77 (b) is to be the method for the error of unit inspection message point in order to illustrate with sub-dot matrix, shows to make the key diagram of information point I1 to the state arranged side by side of I16.
Error-detecting mode shown in Figure 77 (b) is identical with Figure 77 (a), be to make 1 bit have redundancy, (I1, I2, I3, I4), (I5, I6, I7, the I8) that constitutes with 4 information points 3, (I9, I10, I11, I12), (I13, I14, I15, I16) separately independently data (3 bits * 4=12 bit) be the mode of unit inspection error.
Get final product 100% ground like this and check out whether the information point 3 of dot pattern 1 has printing error on the medium face such as printed article whether the flexible of medium face is arranged and because the deviation during pixelation, whether, disposed the position deviation of information point 3 with other data to adjacent.
Figure 78 is by giving the next Bit Allocation in Discrete " 0 ", the key diagram of the method for the error of inspection message point.
Figure 79 is by giving the next Bit Allocation in Discrete " 1 ", the key diagram of the method for the error of inspection message point.
So, if with the direction dictates of keying point 2 is last direction, to be made as by the data of the information point 3 of this direction definition " 0 ", also can be on any direction that information point 3 is configured in 8 directions in, by giving the error of the next Bit Allocation in Discrete " 1 " inspection message point 3.That is to say, give the next Bit Allocation in Discrete the information point 3 of " 1 " to be usually located at the image point be on the incline direction at center.Therefore, be positioned at up and down or on the left and right directions time, decidable is not for being presented on the appropriate position when this information point 3.
Figure 80 is to the next bit alternate allocation " 0 " and " 1 ", the key diagram of the method for the error of inspection message point.
Also have, in 1 information point 3 of common configuration,, also can check the error of this information point 3 by giving the next bit alternate allocation " 0 " and " 1 " in order to be used for error-detecting.Among this error-detecting mode, can about, about, 45 degree alternately generate information point on the incline directions, eliminate the regularity of dot pattern.That is to say, give the next bit alternate allocation the information point 3 of " 0 " and " 1 " be usually located at the image point be the center about, about or on 45 incline directions.Therefore, about this information point 3 is positioned at, about or on the direction of 45 degree beyond the incline directions time, be judged to be and be not presented on the appropriate position.As mentioned above, can check out accurately that information point 3 departs from the image point error of the direction of rotation input that is the center.
When information point 3 being set at 8 directions (45 degree at interval) and when different in size (with reference to Figure 74), if in 4 bits, the next 1 bit is made as " 0 " or " 1 ", then under the situation of the some position of having departed from 3 points close to each other (1 point in concentric circles ± 45 degree position of rotation, 2 points+length), can be with this as error, error is checked out on 100% ground.
Figure 81 is the security for descriptive information point, and expression makes the key diagram of information point I1～I16 state arranged side by side.
For example, for the data that make dot pattern 1 can't with the naked eye be found out,,, after the input point pattern I n, ask for Kn=In-Rn with dot pattern 1 performance In=Kn+Rn to the computing that the In of information point 3 implements to use function (Kn) performance.
Perhaps, in order with the naked eye to find out the data of dot pattern 1, can be by being representative point with keying point 2, a plurality of information points 3 are configured to 1 row, and these 1 row are configured to multiple row, the difference of the data of adjacent two row as the data of information point 3, is disposed each information point 3, so that eliminate the regularity of the dot pattern 1 of each dot matrix.
So, owing to can't with the naked eye find out the dot pattern that prints on the medium face, thereby can improve security.In addition, when being printed onto aforementioned dot pattern 1 on the medium face, but random arrangement information point 3 disappears pattern, and it is unshowy that dot pattern becomes.
Figure 82 is the routine key diagram of another kind configuration of the dot pattern of the expression allocation position that changed keying point.
(the explanation of dot pattern: GRID-2)
Use the basic principle of the dot pattern of description of drawings GRID-2 below.
At first, shown in Figure 83, on the XY direction every predetermined distance supposition graticule (y1～Y7, x1～x5).The intersection point of this graticule is referred to as grid point.And in the present embodiment, as the minimum dot matrix (1 mesh) that these 4 grid point center on, with 4 dot matrix on the xy direction (4 meshes), promptly 4 * 4=16 dot matrix (16 meshes) is as 1 block of information.The unit of this block of information is decided to be only a kind of illustration of 16 dot matrix, obviously the dot matrix configuration information piece of any number.
And 4 angle points that will constitute the rectangular area of this block of information are set at angle point (x1y1, x1y5, x5y1, x5y5) (among the figure, the point that rises with circle).Make these 4 angle points consistent with grid point.
So, by finding out 4 angle points consistent with grid point, can the identifying information piece.But, if only depend on this angle point, be block of information even can identify, it is towards still not understanding.If this is because direction that can not the identifying information piece, even same block of information, if scanning rotation ± 90 degree or 180 degree also can become diverse information.
Therefore, disposed vector point (keying point) on the grid point in the inside of the rectangular area of block of information or adjacent rectangular area.In the figure, the point (xy3) that triangle enclosed is exactly keying point (a vector point), and this keying point is configured on the 1st grid point of vertical line top of mid point of form line of configuration information piece top.Identical therewith, in this block of information, constitute the keying point that has disposed next block of information on the 1st the grid point (x4y3) on the plumb line of mid point of following graticule.
In the present embodiment, (between mesh) distance between grid is made as 0.25mm.Therefore, one side block of information be 0.25mm * 4 meshes=1mm.And this area is 1mm * 1mm=1mm
2The information that can hold 14 bits in this zone under the situation of 2 bits as the control data use wherein, can be held the information of 12 bits.(between mesh) distance between grid is made as only a kind of illustration of 0.25mm, also can in the zone of for example 0.25～0.5mm, freely changes.
Among this GRID-2, information point be configured in every one promptly from grid point on the position of x direction, y direction dislocation.The diameter of information point is more preferably greater than 0.03～0.05mm, apart from the bias of grid point preferably be set in lattice spacing from about 15～25%.Because this bias also is a kind of illustration, thereby also can be not in this zone, but set bias greater than under 25% the situation usually, when detecting by an unaided eye, dot pattern formation pattern has easy found tendency.
That is and since about alternately becoming apart from the offset manner of grid point (y direction) depart from and about the departing from of (x direction), thereby the configuration skewness of point disappears, and can't see Moire fringe and decorative pattern on the paper, can keep the attractive in appearance of printing paper surface.
By adopting this kind equipping rules, information point is on a graticule that must be configured in y direction (with reference to Figure 84).So done following benefit.When reading dot pattern, as long as find the graticule that disposes every on the straight line of y direction or x direction, the computational methods in the information processor in the time of can making identification are oversimplified and high speed.
In addition, under the situation of thereby distortion former because of paper bending etc. when dot pattern, graticule often can not constitute correct straight line, but owing to be the mild curve of near linear, the discovery of graticule is more or less freely, thereby can be described as a kind of error and very strong computing method of tilt capability of tackling the paper distortion and reading optical system.
See 85 figure about the explanation of information point content.In the figure ,+be grid point.Be point (information point).With respect to grid point, information point is configured in-be made as 0 during the y direction, information point is configured in+be made as 1 during the y direction, with respect to same grid point, information point is configured in-be made as 0 during the x direction, information point is configured in+be made as 1 during the x direction.
The configuration status of concrete information point is described and reads computing method with Figure 86 below.
Among this figure, owing to be with the information point (information point (1) hereinafter referred to as) of the numeral 1 of circle to compare with grid point (x2y1), deflection+x direction, thereby be " 1 ".In addition, because information point (2) (being the numeral of band circle among the figure) is compared with grid point (x3y1), deflection+y direction, thereby be " 1 ", also have, because information point 3 (being the numeral of band circle among the figure) is compared with grid point (x4y1), deflection-x direction, thereby be " 0 ", information point (4) (numeral of band circle among the figure) is " 0 ", information point (5) is " 0 ".
Under the situation of the dot pattern shown in Figure 86, information point (1)～(17) are following value.
(1)＝1
(2)＝1
(3)＝0
(4)＝0
(5)＝0
(6)＝1
(7)＝0
(8)＝1
(9)＝0
(10)＝1
(11)＝1
(12)＝0
(13)＝0
(14)＝0
(15)＝0
(16)＝1
(17)＝1
In the present embodiment, be further to obtain computing method to calculate this value for above-mentioned information bit, but also this information point directly can be exported as information bit with the information of employing calculus of finite differences described below.In addition, for this information bit, also can calculate true value by the value of calculation process security table described later.
With Figure 86 the information acquisition method that has used as the calculus of finite differences of GRID-2 feature is described below.
In description of the present embodiment, the numeral that centers on square in the digital watch diagrammatic sketch that centers on the circular numeral that centers on (numeral of band circle) usefulness [] in the digital watch diagrammatic sketch that centers on ().
Among present embodiment, the 14 bits value separately in the block of information is by the difference performance of adjacent information point.For example, the 1st bit can be by obtaining with the difference that is positioned at the information point (5) on x direction+1 grid position with respect to information point (1).That is to say [1]=(5)-(1).Because information point (5) herein is " 1 ", information point (1) is " 0 ", thereby the 1st bit [1] is " 1 " for 1-0.Identical therewith, the 2nd bit [2] available [2]=(6)-(2), the 3rd bit can be used [3]=(7)-(3) expression.The 1st bit～the 3rd bit such as following.
In following differential type, value takes absolute value.
[1]＝(5)-(1)＝0-1＝1
[2]＝(6)-(2)＝1-1＝0
[3]＝(7)-(3)＝0-0＝0
Then, about the 4th bit, obtain with being positioned at the information point (8) under the vector point and the difference of information point (5).Therefore, the 4th bit [4]～the 6th bit [6] get be positioned at+the x direction on 1 grid, the difference of the value of the information point of 1 grid on the+y direction.
Be that available following formula is obtained the 4th bit [4]～the 6th bit [6] like this.
[4]＝(8)-(5)＝1-0＝1
[5]＝(9)-(6)＝0-1＝1
[6]＝(10)-(7)＝1-0＝1
Then, about the 7th bit [7]～the 9th bit [9], get be positioned at+the x direction on 1 grid, the difference of the value of the information point of 1 grid on the-y direction.
Be that available following formula is obtained the 7th bit [7]～the 9th bit [9] like this.
[7]＝(12)-(8)＝0-1＝1
[8]＝(13)-(9)＝0-0＝0
[9]＝(14)-(10)＝0-1＝1
Then, about the 10th bit [10]～the 12nd bit [12], get be positioned at+the x direction on the difference of information point of 1 grid, specific as follows.
[10]＝(15)-(12)＝0-0＝0
[11]＝(16)-(13)＝1-0＝1
[12]＝(17)-(14)＝1-0＝1
At last, the 13rd bit [13] and the 14th bit [14], to information point (8), get with the x direction on lay respectively at+difference of information point on 1 ,-1 grid position, ask in the following manner.
[13]＝(8)-(4)＝1-0＝1
[14]＝(11)-(8)＝1-1＝0
Also can be with the 1st bit [1]～the 14th bit [14] directly as true value, as reading The data, but for guaranteeing security, also can be by setting in advance the security table corresponding with this 14 bit, define the keying parameter corresponding, by adding to take advantage of and calculate the keying parameter and obtain true value to reading data with each bit.
In the case, true value T can use Tn=[n]+Kn (n:1～14, Tn: true value, [n]: read value, Kn: the keying parameter) ask for.The security table that has held this kind keying parameter can be logined among the ROM in optical pickup device in advance.
For example,, set under the situation of following keying parameter as security table,
K1＝0
K2＝0
K3＝1
K4＝0
K5＝1
K6＝1
K7＝0
K8＝1
K9＝1
K10＝0
K11＝0
K12＝0
K13＝1
K14＝1
True value T1～T14 can obtain by following respectively
T1＝[1]+K1＝1+0＝1
T2＝[2]+K2＝0+0＝0
T3＝[3]+K3＝0+1＝1
T4＝[4]+K4＝1+0＝1
T5＝[5]+K5＝1+1＝0
T6＝[6]+K6＝1+1＝0
T7＝[7]+K7＝1+0＝1
T8＝[8]+K8＝0+1＝1
T9＝[9]+K9＝1+1＝0
T10＝[10]+K10＝0+0＝0
T11＝[11]+K11＝1+0＝1
T12＝[12]+K12＝1+0＝1
T13＝[13]+K13＝1+1＝0
T14＝[14]+K14＝0+1＝1
More than the corresponding relation of Shuo Ming information bit and security table and true value is shown in Figure 87.
Illustrated more than that behind information point acquired information bit ask for the situation of true value with reference to security table, but also can generate according to true value under the situation of dot pattern in contrast, available [the n]=Tn-Kn of the value of n bit [n] asks for.
As an example herein, under the situation of T1=1, T2=0, T3=1, the available following formula of the 1st bit [1]～the 3rd bit [3] is asked for.
[1]＝1-0＝1
[2]＝0-0＝0
[3]＝1-1＝0
And the available following differential type of the 1st bit [1]～the 3rd bit [3] is represented.
[1]＝(5)-(1)
[2]＝(6)-(2)
[3]＝(7)-(3)
Herein, one pays the initial value of (1)=1, (2)=1, (3)=0, can point (5)～(7) of obtaining as described below.
(5)＝(1)+[1]＝1+1＝0
(6)＝(2)+[2]＝1+0＝1
(7)＝(3)+[3]＝0+0＝0
Though following explanation is omitted, the value of point (8)～(14) also can be asked for equally, gets final product according to this value collocation point.
And the initial value of point (1)～(3) is any random number (0 or 1).
That is, add the value of information bit [1]～[3], can obtain the value that is configured in point (5)～(7) on the following y direction graticule by giving initial point (1)～(3 of distributing).Identical with it, by the value of information bit [4]～[6] that on the value of point (5)～(7), add, can obtain the value of point (8)～(10), also have, by the value of the information bit that on these, adds [7]～[9], can obtain the value of point (12)～(14).Also have,, can obtain the value of point (15)～(17) thereon as if the value of information bit [10]～[12] that add.
About point (4) and (11), can subtract and calculate information bit [13] by according to the aforementioned point (8) that calculates, the information bit that adds [14] is asked for respectively.
As mentioned above, in the present embodiment, according to the some configuration on the configuration of the point on the graticule y (n-1) the decision graticule yn, by repeating the configuration that this process can determine all information points successively.
More than be that imagination uses the GRID-1 of above explanation and the dot pattern of GRID-2 that following concrete example is described, but in following concrete example, it is not the dot pattern computing method that only can be suitable for the GRID-1 or the GRID-2 of above explanation, so long as hold the technology of information, can use any dot pattern by dot pattern.
Concrete example (1)
In following concrete example, with in the zone that responds at optics imaging apparatus such as cmos sensors and the printing ink (reaction printing ink) of absorption infrared ray or ultraviolet wavelength be typical example, with having used the example that absorbs the carbon element printing ink of IR wavelength to be illustrated, even but carbon containing not gets final product so long as have the printing ink of these characteristics.For example,, absorb the printing ink of ultrared characteristic, can use near transparent printing ink (invisible printing ink) as having carbon-free molecular structure.By using this kind, can will set to such an extent that be difficult to more find near transparent so-called steady shape printing ink.
Fig. 1 uses and the carbon element ink printing point of paper with colour system, uses the non-carbon element printing ink of 4 looks (YMCK) to implement common printed example on this.
If adopt this concrete example, owing to be what to use with the color printing point of the identical colour system of color of paper (medium face), thereby with the naked eye be difficult to find out this point.
Black) or blue or green (C) printing points in this concrete example, when the paper look is pure white or almost under the situation of nattierblue near white, carbon content is controlled at ash about a few percent (K:, then can make and carry out common printed zone on it and be difficult to find out a little if use.Obviously, if use the invisible printing ink (trade (brand) name) that does not contain carbon element but in the IR wavelength zone, respond, then be difficult to identification with the naked eye.
In addition, when using primary colors and containing under the situation than the paper (medium) of warm tones color, preferably use Y printing ink and invisible printing ink (trade (brand) name) printing points.
Carbon content in the printing ink is preferably in about 10%, but, by improving the shooting performance of element, has only a few percent even carbon contains, and also can discern with the infrared optical reading device.
Concrete example (2)
This concrete example is as Fig. 2 (a) and (b), is to make the example that naked eyes can't identification point by the printing opaque ink that further overlaps on the point of going up printing at paper (medium face).
Opaque ink herein is meant the printing ink that visible light can't see through.That is to say, can pass through that the short visible light of wavelength can't pass, realize that naked eyes can not discern by making the long infrared ray of ripple, and the dot pattern that infrared ray is responded.
That is to say, on paper (medium face) at first with (Fig. 2 (a)) after the carbon element ink printing point, use color or its advancing colour of this paper, or the zone (Fig. 2 (b)) of any topped aforementioned point of opaque non-carbon element ink printing, and then the non-carbon element printing ink with 4 kinds of colors (CMYK) carries out common printed on this.
At this moment, under state shown in Fig. 2 (b), because printing by opaque non-carbon element printing ink, point is by topped, thereby with the naked eye can't identify hereunder the point of printing, but because the penetrable aforementioned opaque non-carbon element ink lay of infrared ray, partly be absorbed at the point of carbon element printing ink, infrared ray can not be from this partial reflection, and therefore available optical pickup device is accurately discerned this point.
Under the situation of using the non-carbon element printing ink of preparing as characteristic of White-opalescent because opacity is original just high, even thereby the some printing use with common black (K) carbon element printing ink, still can keep very high disguise.
Among above explanation, for be only on paper with the carbon element ink printing zone of point with the overlap example of printing of opaque ink, but also can at first, use the whole paper surface of opaque non-carbon element ink printing more as shown in Figure 3 with after the carbon element ink printing point (Fig. 3 (a)).(Fig. 3 (b)).
In the case, comprehensive printing of adopting opaque non-carbon element printing ink to carry out, available random color.
At this moment, identical with Fig. 2 explanation, under the state shown in Fig. 3 (b), owing to the printing by opaque non-carbon element printing ink, point has been capped, thereby the point of printing hereunder can't with the naked eye be discerned, but because infrared ray can see through aforementioned opaque non-carbon element layer, be absorbed on the some part of carbon element printing ink, infrared ray can't be from this some part reflection, therefore, available infrared optical reading device is accurately discerned this point.
And the carbon element color of ink of printing points needs not to be black (K).That is to say, as long as this is that no matter which kind of color all is expected to have aforementioned infrared absorption effect because contain the carbon of aforementioned a few percent.
By being predetermined the opaque non-carbon element color of ink on the upper strata of on whole paper, printing, at the some use of its lower floor's printing and the carbon element printing ink of the approximate color of color of aforementioned comprehensive printing, can more effectively hidden point.
Concrete example (3)
Concrete example shown in Figure 4 is to use and background 4 looks (chromatic number is any) of this position carbon element ink printing point with a kind of color, makes color a little sneak among the color of periphery easier hidden example.
Fig. 4 (a) illustrates common single color point, and Fig. 4 (b) illustrates the point with the concentric circular regions formation of 4 kinds of colors.
This concrete example is to be prerequisite with the net-point printing that adopts the AM print process, the technology of the point that printing is disguised high.
This figure (b) illustrates the example with the carbon element ink printing point of 4 looks.
In the case, the point of shades of colour (4 look) is the concentric circles printing, prints Y (Huang), M (dark red), C (green grass or young crops), K (deceiving) successively from lower floor.
The size of each color dot of printing is by making the diameter of the highest color of color range (color range high luminance relay: be Y herein)
Diameter with dot pattern
Unanimity,
The site amount (%) of the high luminance relay of this color range is made as X0%, when the colored site amount of ask is made as x%, diameter of all kinds
Available following formula calculates.
Therefore, amount is 70% when the site of Y, and the site amount of M is 50%, and the site amount of C is 30%, and the site amount of K is 20% o'clock, and diameter of all kinds is following (with reference to Fig. 5 (a)) respectively.
In addition, K (black) composition is overlapped under the situation on the various compositions of C, M, Y diameter of all kinds following (with reference to Fig. 5 (d)) respectively.Can overlap on the various compositions of other C, M, Y by making K composition (black content) like this, reduce the use chromatic number of printing ink.
Wish further to reduce under the situation of chromatic number, dominant by certain color among this printing, or wish certain color showy (purpose look), only this purpose look is used for a little also can reducing the chromatic number that constitutes point.
In addition, if adopt this concrete example,, be not only to show dot pattern simultaneously with the K of carbon element printing ink owing to not only make a little hiddenly easily, can prevent the color blackening that the K that sneaks into carbon element printing ink outside the K because of the non-carbon element printing ink that uses on the common printed site produces.
Concrete example (4)
The concrete example of Figure 6 and Figure 7 illustrates by color separation processing and only extracts a little know-why.
In this concrete example, illustrate and do not use black (K) when common printed, only use CMY printing ink to carry out, the recognition methods when only constituting the point of dot pattern with black (K) performance.
At this moment, the printing ink that uses in the printing of common printed and point is so long as printing ink that can optical identification in the visible light zone, and any printing ink all can.
Carry out color separation processing after the coloured image input RGB picture buffer that the paper (medium face) that this kind of employing method is printed has used the camera head of CMOS imaging apparatus, CCD imaging apparatus etc. to take in optical pickup device.Fig. 6 (a) illustrates the RGB composition ratio of all kinds of this moment.
Generally speaking, among the CMOS of optically read element etc., there is the characteristic that more or less when reading.This be because, color component deflection is of the same colour, when influence power was big, other color also was subjected to its index, or inconsistency is also influential during fabrication, for example, the result who reads often is the image (with reference to Fig. 6 (a)) of whole general green grass or young crops.If this specific character image is implemented dot pattern identification, under the situation of color separation processing, because the existence of cyan composition, the point of K printing ink (black) often is difficult to read as black, error occurs reading.Therefore, when reading, revised.
That is, from the image that reads, retrieve the pixel of minimum as a result that adds of RGB.So, RGB's adds as a result that the pixel of minimum is a little certainly.At this moment, occur among the RGB having only under the high inconsistent situation of B value, be corrected for the strong image of cyan as can be known.Therefore with the pixel rgb value separately of the minimum as a result of adding of RGB as revising a reference value, from other pixel, deduct this correction a reference value (Fig. 6 (b)～(c)).So, the revised image of CMOS can revert to the state before revising.
Then as previously mentioned, to revised image (for example Fig. 6 (d)), get the maximum of RGB data of each pixel and the mean value of minimum of a value, width by when Fig. 6 (f) (for example) compression aforementioned areas α when the tonal gradation of this mean value is high, (for example Fig. 6 (e)) widened the width of aforementioned areas α when aforementioned tonal gradation was hanged down, and can make to adopt the identification of dot pattern in the visible light zone of K printing ink (black) more easy.
Among each pixel, subtract when calculate handling aforementioned RGB composition, become under the situation of negative value and be made as 0 without exception.And calculate the correction a reference value after a plurality of samplings of the also available pixels of the extraction of this RGB Minimum Area.
In this concrete example, outside the point with CMY printing under the situation of dark netrual colour (grey) since can not with the some difference of adopting color separation processing, thereby identification point only.But, if printing only is light netrual colour (grey), because the conduct point identification of this part, thereby no problem.
Therefore, need not dark-greyly be its prerequisite during printing, but, can identify a little by color separation processing if adopt this concrete example.
Because this concrete example do not need special infrared radiation function and filter function, thereby can from the photographs of shootings such as the digital camera function of adding and WEB camera, identify a little with existing digital camera, mobile telephone terminal.
If conclude above processing procedure, as long as in optical pickup device, implement following process.
1) at first calculates the mean value X of the grade (maximum 100%) of the highest light of RGB of each pixel and low light.
2) then, whether greater than certain value α, judge that this object only denys in tonal gradation (judgement gray scale) according to the difference of the highest light of RGB and low light.
For example establish α=-1/10X+10.
Herein 10 are correction factors, because X infinitely near under 100% the situation, is judged to be tonal gradation 100 (white), thereby no problem, but, implement+10 and revise in order decision errors (in low zone, being judged to be white error) under the low situation of tonal gradation, not occur.
3) under the situation between α＞greatest level-the lowest class, X is set at the grade of tonal gradation.
4) under the situation between α＜greatest level-the lowest class, tonal gradation is set at 100% (white).
5) implement image according to tonal gradation and handle, be judged to be a little after the binarization.
Correction factor is set at 10 herein, but obviously also can be set at other numerical value, the calculating formula of α can be in conjunction with the characteristic definition of CMOS.
Concrete example (5)
This concrete example is with the some double as of the dot pattern example for the black site of printing.
Figure 10 is among the AM print process, during as the point of dot pattern, when the configuration logic of figure was GRID-1, left side figure was the original image of C, M, Y with the site, right figure extracts a part of K composition (black content) from C, M, Y, be the enlarged drawing of the printing surface of site with the dot pattern double as.Among this figure, as the K carbon element ink printing of point.Owing to from original image C, M, Y, only extract the K composition (black content) that measure the site that is equivalent to a little, thereby among C, the M of right figure, Y, there is K composition (black content).That represent this principle is Fig. 7.That is to say, among this figure, from the color component CMY of the periphery of collocation point, extract and can be used as in the common component after the minimum site amount that a little reads this as K composition collocation point.
Figure 11 is among the AM print process, during as the point of dot pattern, when the configuration logic of figure was GRID-1, left side figure was the original image of C, M, Y with the site, right figure be from C, M, Y with the whole extractions of K composition (black content), be the enlarged drawing of printing surface of the site of K with the dot pattern double as.Among this figure,,, be precondition with color seperation identification point with explanation in the concrete example (4) with carbon element printing ink or non-carbon element ink printing as the K of point.
Figure 12 is among the AM print process, with the site be as the point of dot pattern, the configuration logic of figure is that GRID-1 is, left side figure be the original image of C, M, Y, and right side figure extracts the enlarged drawing of printing surface that image prints behind the K composition (black content) of coideal with the dot pattern double as site that is K1 and K2 from original image C, M, Y.Among this figure, K1 is that double as is the site of dot pattern with non-carbon element ink printing, K2 carbon element ink printing, K1, and K2 is used in and can be used as the minimum site amount that a little the reads printing that overlaps in the zone of this K1.Therefore, as long as the point of K2 is less than K1, and the identification that can be used as the free degree is used a little.
Figure 13 is among the AM print process, with the site be as the point of dot pattern, when the configuration logic of figure was GRID-2, left side figure be the original image of C, M, Y, and right side figure is to be the enlarged drawing of net-point printing face with the dot pattern double as after the extraction a part of K composition (black content) from C, M, Y.Among this figure, as the K carbon element ink printing of point.Owing to from original image, only extract the K composition (black content) be equivalent to the site amount, thereby among the C of right figure, M, the Y K composition (black content) is arranged.
Figure 14 is among the AM print process, during as the point of dot pattern, when the configuration logic of figure was GRID-2, left side figure was the original image of C, M, Y with the site, right figure extracts whole K compositions (black content) from C, M, Y, be the enlarged drawing of the printing surface of dot pattern with the site double as of K.Among this figure,, be precondition with color seperation identification point with explanation in the concrete example (4) as K the carbon element printing ink or the non-carbon element ink printing of point.
Figure 15 is among the AM print process, with the site during as the point of dot pattern, when the configuration logic of figure is GRID-1, left side figure be the original image of C, M, Y, and right side figure is that to extract from original image C, M, Y that image prints behind the desirable K composition (black content) the dot pattern double as be the printing surface enlarged drawing of the site of K1 and K2.Among this figure, K1 is that double as is the site of dot pattern with non-carbon element ink printing, K2 carbon element ink printing, K1, and K2 is used in and can be used as the minimum site amount that a little the reads printing that overlaps in the zone of this K1.Therefore, as long as the point of K2 is less than K1, and the identification that can be used as the free degree is used a little.
As mentioned above, the point of this concrete example is the site by double as but departs from the position of former site, with its offset manner definition information.
That is to say that dot pattern is that the intersection point that point is configured in graticule is (grid point) of principle originally, but is at collocation point on one grid point in this concrete example, all the other are then as the information point printing that departs from grid point.
About the definition of this information point, illustrated owing to preceding, thereby omitted its explanation herein.
If adopt this concrete example, as above-mentioned, owing to can be a little with the substantive site double as that exists on the printing surface, thereby with the naked eye identification point almost is unable to handle.
For can all being suitable for the dot pattern that departs from grid point definition information.
In addition, the inventor etc. recognize in order to read with the infrared optics reading device, under the situation with the point of K carbon element ink printing dot pattern, because the some position difference of the K site of the non-carbon element printing ink of printing, thereby if on paper (medium face), repeat print these, finally blackening can appear, but if adopt the present invention, because with the dot pattern double as is the site of K, only in common printed, carry out 4 look printings, thereby blackening appears can be as in addition with K ink printing dot pattern the time, can make printing surface keep beauty.
Under the situation of the black of site (K) double as for point, owing to need make and a little depart from grid point, the possibility of some connection therefore adjacent one another are is big during than common site.Common site is often connecting more than 50%.Therefore, in this concrete example, need the site amount is adapted to maximum about 20～25%.But,, the shape of point handles, even then the site amount still can be discerned above 50% if being made high-precision image.
Fig. 8 illustrates in this concrete example point is printed as foursquare situation, and Fig. 9 illustrates the conglobate situation of printing.
Want under the situation that does not have black (K) colour content fully, or Detection Point under few situation, preferably show a little with site minimum a few percent (if printing precision is low, then percentage should be bigger) that is not less than of amount.
Adopting the infrared radiation mode to be applicable under the situation of this concrete example, also can as shown in figure 16, point be adapted to the size of being convenient to discern print afterwards by in the printing of point, using K carbon element printing ink.
Among Figure 16 (a) and (b), with account for 50% K composition (black content) 30% as this figure (a) ', (b) ' shown in, except that CMY, prevent adjacent some contact by K being reduced 30%.Among this figure, in order to describe, will put at interval and be made as equalization, but as aforementioned, double as to be under the situation of site and information point at the same time, obviously can in this configuration, produce deviation.Figure 17 is the figure of the dot pattern of brief description GRID-1, and it overlaps on the site of square configuration and has disposed the information point of black ring shape.
Concrete example (6)
This concrete example is by being provided with shaded portions in 1 printing image, making this cover shape becomes discernible example.
In this concrete example, by the zone being divided into the part of using non-carbon element printing ink CMYK to print in the image with the regulation shape, and the part of using carbon element printing ink to print, read with the literal of carbon element ink printing and pattern, various code with infrared mode.
Specifically as shown in figure 18, in image, set and wish the hidden shape of covering, then shown in Figure 19 (a), with the part outside the non-carbon element ink printing shaded portions.
Then shown in Figure 19 (b), with carbon element ink printing shaded portions.
So promptly finish the image shown in Figure 19 (c).At this moment, owing to contain the printing ink of carbon element and do not contain the printing ink quality characteristic of carbon element how much different, thereby inharmonious sense appears in order to prevent to detect by an unaided eye, preferably shaded portions or non-shaded portions are carried out the ink colors correction, so that do not see the printing of covering the border.Obviously also can be without carbon element printing ink, and be to use the printing ink that has added invisible printing ink.
If the image shown in this Figure 19 (c) is carried out infrared radiation, read its reverberation with the infrared optical reading device, owing to have only shaded portions to absorb infrared ray with the carbon element ink printing, thereby can identify occlusion image zone shown in Figure 180.What this shaded areas adopted in this concrete example (6) is the shape of the capitalization A of ABC, but should the zone also can adopt the shape of other literal, sign, figure.In addition, the dot pattern printing that illustrates in also available other concrete example of the printing of this shaded areas.
Concrete example (7)
This concrete example illustrates and does not use net-point printing, but adopts hidden (stealth) printing technology of the dot pattern of FM screen mode of printing.
FM screen mode of printing is (with reference to the Figure 20) that utilizes onesize picture element density represent images.
In this concrete example, by the part that only will put, promptly only will constitute the CMY that a little pixel portion is used homochromy carbon element printing ink, remainder then uses non-carbon element printing ink, utilizes infrared radiation to get final product identification point.
But among the point that constitutes dot pattern, shown in Figure 20 (b), in the absence of colouring information, need to distribute the homochromy of periphery with the pixel exchange color of periphery or to pixel as shown in figure 21, generate the shape that can be used as an identification with carbon element printing ink.
In addition, when not having fully among the pixel of periphery under the situation of colouring information, need to come printing points by generating the color that is similar to paper with carbon element printing ink.
In the above embodiment, the situation when using 4 looks (CMYK) carbon element printing ink has been described, but also can be identical with concrete example (3), omit mass colour (K), show with CMY3 look carbon element.That is to say,, from CMYK, remove the K composition, become component to be increased on the CMY this, the color that the color range of raising CMY is come adjusting point at each pixel that constitutes point.Can show a little with CMY3 look carbon element printing ink without black (K) like this, thereby chromatic number is reduced.Do not have in the pixel under the situation of colouring information, can exchange color with the pixel of periphery, or distribute the homochromy of periphery, generate the shape that can be used as an identification with carbon element printing ink to pixel.
In addition, among FM screen mode of printing, also the available point double as is black (K), and the periphery of point is only existing with CMY three color tables.
That is to say, utilize the domination area of point, i.e. (printing area/count), the CMY that the common color range of each color range (maximum 100%) of contained pixel CMY separately in the zone of 1 point has partly been deducted is as the color range of this pixel, the color range of this common ground is added in above-mentioned zone, if remove with 100%, can calculate the pixel count that constitutes the point that available black shows.Can form point (with reference to Figure 22) by on this, disposing black (K) pixel twist from the center of collocation point.
As above-mentioned, identical with the method for concrete example (5), can use the color separation processing technology Detection Point of concrete example (4).
If adopt this concrete example, because needn't be with carbon element printing ink and the non-carbon element printing ink K printing ink (black) of repeating print, thereby can suppress the blackening of printing surface.
But in this concrete example, do not have fully under the situation of black in the domination zone of the point of (on the medium face) on the paper, need to use black (K) the performance point of the minimum pixel number that can be used as an identification.
