In addition, because dot pattern naked eyes are visually present on medium surface, thereby there is infringement medium surface problem attractive in appearance.

Want to avoid occurring this kind of problem, though can consider to adopt the transparent specialty inks printing points figure responding under infrared light or ultraviolet light, have the problem that printing cost is high, reading device is complicated, and unrealistic.Especially in recent years the mobile telephone terminal with camera function being widely used the method that is not suitable for using these optical filters.

The present invention In view of the foregoing puts forward just, and its problem is to provide a kind of technology, and it only improves a little to existing printing technology, can simply and at an easy rate realize and cannot with the naked eye find out the dot pattern on medium surface, be i.e. so-called steady form point figure.

First aspect of the present invention is a kind of print structure of medium surface, it is characterized in that: be the medium surface that forms the dot pattern using in dot pattern reading system, it is by irradiating infrared light or ultraviolet light to being provided with the medium surface of dot pattern, by optics readout means reads, get its reverberation, identify this dot pattern, be transformed to output character after with it corresponding data, sound, image etc.;

The point that forms aforementioned dot pattern can be used on the ink of the random color responding in infrared ray or ultraviolet wavelength region, by printing treatment, is arranged on aforementioned medium surface.

The said ink responding in infrared ray or ultraviolet wavelength region (reaction ink) can exemplify the ink with the characteristic that the light in infrared ray or ultraviolet wavelength region responds herein, more specifically, can exemplify carbon element ink.The in the situation that of unresponsive ink in infrared ray or ultraviolet wavelength region (non-reaction ink), if with the irradiation printing surface (medium surface) in above-mentioned wavelength region, together with visible light, the light of above-mentioned ink face is also reflected, but in the situation that the ink responding in infrared ray or ultraviolet wavelength region, on ink face, absorb the reverberation that light (reaction) in infrared ray or ultraviolet wavelength region does not produce printing surface.

As the ink responding (reaction ink), except aforementioned carbon element ink, can not conform to carbon element in IR wavelength or ultraviolet wavelength region yet.For example as the molecular structure do not conform to carbon element, absorb the ink of infrared ray (reaction) characteristic, can list steady shape ink, its product is respectively for doing dense ink (trade (brand) name).

Second print structure that aspect is a kind of medium surface of the present invention, it is characterized in that: be the medium surface that forms the dot pattern using in dot pattern reading system, it is by irradiating infrared light or ultraviolet light to being provided with the medium surface of dot pattern, by optics readout means reads, get its reverberation, identify this dot pattern, be transformed to output character after with it corresponding data, sound, image etc.;

The point that forms aforementioned dot pattern can be used on the ink responding in infrared ray or ultraviolet wavelength region, by printing treatment, uses with the color of the identical colour system of color of aforementioned medium surface and is arranged on aforementioned medium surface.

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 that marks same label in figure represents same object.

First, the principle of the dot pattern using in the present invention 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 to GRID1 and GRID2.

GRID1 is No. PCT/JP03/03162 application that the inventor proposes, and GRID-2 is No. PCT/JP03/16763 application.

(dot pattern explanation: GRID-1)

Figure 71 is the figure that illustrates of dot pattern of the present invention.Figure 72 is the information point of dot pattern and the bit of the data of definition shows thus illustration enlarged drawing.Figure 73 means the key diagram that keying point is configured in to the information point at center.

Use the information I/O method of dot pattern of the present invention by the generation of dot pattern 1, the identification of this dot pattern 1 and forming according to the device of this dot pattern output information and program.; utilizing the camera of dot pattern camera head (can be also optical pickup device, the digital camera being connected with PC; camera function with the mobile telephone terminal of camera) after obtaining view data; utilize reading device, PC or with the analysis program of installing in the mobile telephone terminal of camera; first extract grid point; then by beating, there iing not the original locational point of grid point to extract keying point 2; then by information extraction, put 3 and make it digitlization, be transformed to the code of information digitalization after extracting information area.And make it the voice data that is associated with this yard of output and out of Memory, program.In addition, information point 3 can not be both code but coordinate values, also can be by digitlizations such as voice data and out of Memory.

The generation utilization point point coding generating algorithm of dot pattern 1 of the present invention, according to the regularly arranged keying point 2 of predetermining, information point 3, grid point 4.At GRID-1, among, shown in Figure 71, represent that the dot matrix of the dot pattern 1 of information configures 5 * 5 grid point 4 centered by keying point 2,4 grid point 4 around the image point at center around configuration information point 3.This dot matrix definable Any Digit information.Shown in the legend of Figure 71 in the section of dot pattern 1 (bold box) configured side by side the state of 4.But obviously, dot pattern 1 is not limited to 4 sections.

1 information and the program of correspondence with it be can in a section, login, or 1 information and the program of correspondence with it in a plurality of sections, logined.

Grid point 4 when the dot pattern 1 obtaining with camera as view data, the distortion when bending of flexible, the medium surface of the distortion of the camera lens of rectifiable this camera and oblique shooting, paper, printing.Particularly, obtain 4 grid point 4 of distortion are transformed to foursquare function (Xn, Yn)=f (X ' n, Y ' n) for correction, with obtaining the vector of correct information point 3 after this Same Function update information point.

If configure grid point 4 in dot pattern 1, with camera, obtain the view data of this dot pattern 1 owing to can revising the distortion being caused by camera, even if thereby when obtaining the view data of dot pattern 1 with the popular camera that the camera lens that deformation rate is high has been installed, also can correctly identify.In addition,, even if the face that camera is favoured to dot pattern 1 reads, also can correctly identify this dot pattern 1.

Keying point 2 is as shown in Figure 71, is the grid point of rectangular arrangement 4 is positioned to 1 grid point 4 on center substantially to the point of certain orientation dislocation configuration.This keying point also can configure (with reference to Figure 82) to certain orientation dislocation by the grid point that forms four angles of dot matrix.This keying point 2 means the representative point of the dot pattern 1 in 1 dot matrix of information point 3.For example, make dot pattern 1 dot matrix center grid point 4 upwards dislocation form.When information point 3 represents that in X, Building Y target situation, the center of dot matrix becomes representative point, but this numerical value (number) is not limited to this, can be according to the corresponding change of dot matrix size of dot pattern 1.

In addition, though keying point 2 is configured in the center of dot matrix, be not limited to this, also the grid point that forms the bight of dot matrix can be configured as benchmark.

Information point 3 is the points that make various information identifications.This information point 3 be take keying point 2 as representative point, is configured in it around time, using the grid point of 44 around center as image point, as initial point, be configured on the terminal by vector performance.For example, this information point 3 by grid point 4 around, shown in Figure 72, be configured in point this image point misalignment position in order to there is direction and the length of available vector performance, be configured in 8 directions of each rotation 45 degree clockwise, show as 3 bits.Therefore, the dot pattern 1 of available 1 dot matrix performance 3 bit * 16=48 bits.

In illustrated example, by being configured in 8 directions, show 3 bits, but be not limited to this, also can show 4 bits by being configured in 16 directions, obviously can carry out numerous variations.

Information point 3 and 4 s' grid point 4 around the interval of 15～30% left and right of adjacent image point spacing preferably, interval of image point.This is because if the distance between information point 3 and image point is greater than this interval, each point is easily seen as large agglomerate, is difficult to find out dot pattern 1.In contrast, if the distance between information point 3 and image point is less than this interval, be difficult to assert the information point that makes it to have direction vector centered by adjacent any image point.

For example, information point 3, as shown in Figure 73, is configured in the clockwise direction in the region from I1 to I16 centered by keying point 2, can show as 3 bits * 16=48 bit.

In dot matrix, there is separately the independently information content, the sub-dot matrix that is not subject to out of Memory content influence also can be set.Figure 73 is the diagram of this situation, and the sub-dot matrix that 4 information points form (11,12,13, I4), (I5, I6, I7, I8), (I9, I10, I11, I12), (I13, I14, I15, I16) are separately the form that independently data (3 bits * 4=12 bit) are launched in 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 thus represents, is another kind of mode.

In addition, if for information point 3, from grid point 4 around image point use long and short two kind, direction vector is set as to 8 directions, can show 4 bits.At this moment, a long side is 25～30% left and right of the distance between adjacent image point preferably, and a short side is 15～20% left and right preferably.But the Center Gap of length information point 3 is more preferably greater than the diameter of these points.

By 4 grid point 4 around information point 3 consider outward appearance, 1 point preferably.But, when paying no attention to outward appearance, wish to set in the situation of more information amount, by giving each vector assignment 1 bit, by a plurality of bit performance information points 3, can have a large amount of information.For example, on the vector of concentrically ringed 8 directions, available 4 grid point 4 around information point 3 performance 2 ⁸information, by 16 information points of a dot matrix, become 2 ¹²⁸.

Figure 75 is information point and the table of bits example of data of definition thus, (a) represents to have configured 2 points, (b) represents to have configured 4 points, (c) represents to have configured 5 points.

Figure 76 is the variation of dot pattern, is (a) 6 information point layout types, is (b) 9 information point layout types, is (c) 12 information point layout types, (d) is the sketch of 36 information point layout types.

Dot pattern 1 shown in Figure 71 and Figure 73 is by having configured the individual illustration that configures information point 3 in 16 (4 * 4) at a dot matrix.But, this information point 3 is not limited in a dot matrix and configures 16, can carry out numerous variations.For example, can be according to the resolution of the size of information needed amount or camera, in a dot matrix, configure 6 (2 * 3) individual information points 3 (α), in a dot matrix, configure 9 (3 * 3) information points 3 (b), and in a dot matrix, configure 12 (3 * 4) individual information points 3 (c), or in a dot matrix, configure 36 (6 * 6) information points 3 (d).

Figure 77 (a), (b) are for the method for inspection message point tolerance is described, the key diagram with 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 there is redundancy, by homogeneity, process 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, under the state being presented on the medium surfaces such as printed article in information point 3, different with the next bit obtaining 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 appropriate position.

In addition, Figure 77 (b) take in order to illustrate the method that sub-dot matrix is the error of unit inspection message point, shows and makes information point I1 to the key diagram of the state arranged side by side of I16.

Error-detecting mode shown in Figure 77 (b) is identical with Figure 77 (a), to make 1 bit there is redundancy, (I1, I2, I3, I4), (I5, I6, I7, the I8) that 4 information points 3 of take form, (I9, I10, I11, I12), (I13, I14, I15, I16) separately independently data (3 bits * 4=12 bit) be the mode of unit inspection error.

Whether get final product like this information point 3 that 100% ground checks out dot pattern 1 has printing error on the medium surfaces such as printed article whether to have the flexible of medium surface and the deviation during due to pixelation, whether, to adjacent, configured the position deviation of the information point 3 with other data.

Figure 78 is by distributing " 0 ", the key diagram of the method for the error of inspection message point to the next bit.

Information point 3 can be by distributing " 0 " or " 1 " to this next bit, for error-detecting.In information point 3, be presented under the state on medium surface, can determination information point 3 centered by image point, when disposing the position of information point of other adjacent data, can be judged to be information point 3 and not be presented on appropriate position.For example, if the direction gage of keying point 2 is decided to be to upper direction, the data of the information point by this direction 3 definition are made as to " 0 ", when information point 3 is configured in to any one in 8 directions, for for checking that error distributes " 0 " to the next bit.That is to say, give the next bit distributed the information point 3 of " 0 " be usually located at centered by image point up and down or on left and right directions.Therefore,, when this information point 3 is positioned at incline direction, can be judged to be and be presented on appropriate position.

Figure 79 is by distributing " 1 ", the key diagram of the method for the error of inspection message point to the next bit.

So, if the direction gage of keying point 2 is decided to be to upper direction, the data of the information point by this direction 3 definition are made as " 0 ", also can be on any direction that information point 3 is configured in to 8 directions in, by distributing the error of " 1 " inspection message point 3 to the next bit.That is to say, distributed the information point 3 of " 1 " to be usually located on the incline direction centered by image point to the next bit.Therefore, when this information point 3 is positioned at up and down or on left and right directions time, can be judged to be and not be presented on appropriate position.

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, for for error-detecting, also can, by the next bit alternate allocation " 0 " and " 1 ", check the error of this information point 3.Among this error-detecting mode, can on upper and lower, left and right, 45 degree incline directions, replace information generated point, 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 centered by image point up and down, on left and right or 45 incline directions.Therefore,, in the time of in the direction when this information point 3 is positioned at up and down, beyond left and right or 45 degree incline directions, be judged to be and be not presented on appropriate position.As mentioned above, can accurately check out that information point 3 departs from the error of the direction of rotation input centered by image point.

When information point 3 being set as to 8 directions (45 degree interval) and when different in size (with reference to Figure 74), if the next 1 bit is made as to " 0 " or " 1 " in 4 bits, in the situation that departed from the some position of 3 points close to each other (1 point in the degree position of rotation 2 points+length of concentric circles ± 45), can be using this as error, 100% ground checks out error.

Figure 81 is the security for descriptive information point, represents to make the key diagram of information point 11～116 states arranged side by side.

For example, for the data of dot pattern 1 cannot with the naked eye be found out, the In of information point 3 is implemented to the computing with function (Kn) performance, with dot pattern 1 performance In=Kn+Rn, after input point pattern I n, ask for Kn=In-Rn.

Or, in order with the naked eye to find out the data of dot pattern 1, can be by take keying point 2 as representative point, a plurality of information points 3 are configured to 1 row, and these 1 row are configured to multiple row, data using the difference of the data of adjacent two row as information point 3, configure each information point 3, to eliminate the regularity of the dot pattern 1 of each dot matrix.

So, owing to cannot with the naked eye finding out the dot pattern printing on medium surface, thereby can improve security.In addition, when aforementioned dot pattern 1 is printed onto on medium surface, can random arrangement information point 3, pattern is disappeared, it is unobvious that dot pattern becomes.

Figure 82 means that the another kind of the dot pattern of the allocation position that has changed keying point configures routine key diagram.

Keying point 2 might not be configured in the center of dot matrix of the grid point 4 of rectangular arrangement.For example aforementioned, the bight of the configurable dot matrix in grid point 4.At this moment, information point 3 preferably be take keying point 2 and is configured side by side as starting point.

(the explanation of dot pattern: GRID-2)

The basic principle of the dot pattern of GRID-2 is described with accompanying drawing below.

First, as shown in Figure 83, in XY direction, every predetermined distance, suppose graticule (y1～Y7, x1～x5).The intersection point of this graticule is referred to as to grid point.And in the present embodiment, as these 4 grid point around minimum dot matrix (1 mesh), by 4 dot matrix in xy direction (4 meshes), 4 * 4=16 dot matrix (16 meshes) is as 1 block of information.The unit of this block of information is decided to be to only a kind of illustration of 16 dot matrix, obviously the dot matrix configuration information piece of any number.

And 4 angle points that form the rectangular area of this block of information are set as to angle point (x1y1, x1y5, x5y1, x5y5) (in figure, the point rising with circle).Make these 4 angle points consistent with grid point.

So, by finding out 4 angle points consistent with grid point, can identifying information piece.But, if only depend on this angle point, even if can identify, be block of information, it is towards still not understanding.If this is because direction that can not identifying information piece, even same block of information, if scanning rotation ± 90 degree or 180 degree also can become diverse information.

Therefore, in the grid point in the inside of the rectangular area of block of information or adjacent rectangular area, configured vector point (keying point).In the figure, the point (xy3) that triangle encloses is exactly keying point (vector point), and this keying point is configured in 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, form the keying point that has configured next block of information in the grid point (x4y3) of the 1st on the plumb line of mid point of following graticule.

In the present embodiment, (between mesh) distance between grid is made as to 0.25mm.Therefore, one side block of information be 0.25mm * 4 mesh=1mm.And this area is 1mm * 1mm=1mm ².In this region, the information of 14 bits can be held, when using 2 bits wherein as controlling in the situation of data use, the information of 12 bits can be held.(between mesh) distance between grid is made as to only a kind of illustration of 0.25mm, also can in the region of for example 0.25～0.5mm, freely changes.

Among this GRID-2, information point be configured in every one from grid point to x direction, the wrong bit position of y direction.The diameter of information point is more preferably greater than 0.03～0.05mm, apart from the bias of grid point be preferably set in lattice spacing from 15～25% left and right.Because this bias is also a kind of illustration, thereby also can be not in this region, but conventionally bias is set to such an extent that be greater than in 25% situation, while detecting by an unaided eye, dot pattern forms pattern, has easy found tendency.

That is, because the offset manner apart from grid point alternately becomes departing from of (y direction) and departing from of left and right (x direction) up and down, thereby the disappearance of the configuration skewness of point, on paper, can't see Moire fringe and decorative pattern, can keep the attractive in appearance of printing paper surface.

By adopting this kind of equipping rules, information point is on a graticule that must be configured in y direction (with reference to Figure 84).So be made with following benefit.While reading dot pattern, as long as find the graticule configuring every on the straight line of y direction or x direction, the computational methods in the information processor in the time of can making to identify are simplified and high speed.

In addition, in the situation of thereby distortion former because of paper bending etc. when dot pattern, graticule often can not form correct straight line, but owing to being the mild curve of near linear, the discovery of graticule is comparatively easy, thereby can be described as a kind of error and very strong computing method of tilt capability of tackling paper distortion and reading optical system.

About the explanation of information point content, see 85 figure.In the figure ,+be grid point.Point (information point).With respect to grid point, information point is configured in-y is made as 0 during direction, and information point is configured in+y is made as 1 during direction, and with respect to same grid point, information point is configured in-x is made as 0 during direction, and information point is configured in+x is made as 1 during direction.

With Figure 86, the configuration status of concrete information point is described and reads computing method below.

Among this figure, because the information point (hereinafter referred to as information point (1)) of the numeral 1 with circle is compared with grid point (x2y1), deflection+x direction, thereby be " 1 ".In addition, because information point (2) (being the numeral with circle in figure) is compared with grid point (x3y1), deflection+y direction, thereby be " 1 ", also have, because information point 3 (being the numeral with circle in figure) is compared with grid point (x4y1), deflection-x direction, thereby be " 0 ", information point (4) numeral of circle (in the figure with) is " 0 ", information point (5) is " 0 ".

In 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, for above-mentioned information bit, be further by the information of employing calculus of finite differences described below, to obtain computing method to calculate this value, but also this information point directly can be exported as information bit.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 having used as the calculus of finite differences of GRID-2 feature is described below.

In description of the present embodiment, with () around digital watch diagram in circular around numeral (with the numeral of circle) with [] around digital watch diagram in square around numeral.

Among present embodiment, the value separately of 14 bits in block of information shows by the difference of adjacent information point.For example, the 1st bit can be by obtaining with the difference that is positioned at the information point (5) in the grid position of x direction+1 with respect to information point (1).That is to say [1]=(5)-(1).Because information point (5) is herein " 1 ", information point (1) is " 0 ", thus the 1st bit [1] for 1-0 be " 1 ".Identical therewith, the 2nd bit [2] available [2]=(6)-(2), the 3rd bit can use [3]=(7)-(3) to represent.The 1st bit～3rd bit is 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, with being positioned at information point (8) under vector point and the difference of information point (5), obtain.Therefore, the 4th bit [4]～6th bit [6] get be positioned at+x direction on 1 grid, the difference of the value of the information point of 1 grid in+y direction.

Be that available following formula is obtained the 4th bit [4]～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]～9th bit [9], get be positioned at+x direction on 1 grid, the difference of the value of the information point of 1 grid in-y direction.

Be that available following formula is obtained the 7th bit [7]～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]～12nd bit [12], get be positioned at+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

Finally, the 13rd bit [13] and the 14th bit [14], to information point (8), get with x direction on the difference of information point in lay respectively at+1 ,-1 grid position, ask in the following manner.

[13]＝(8)-(4)＝1-0＝1

[14]＝(11)-(8)＝1-1＝0

Also can be using the 1st bit [1]～14th bit [14] directly as true value, as reading out data, adopt, but for guaranteeing security, also can be by setting in advance the security table corresponding with this 14 bit, define the keying parameter corresponding with each bit, by reading out data is added, take advantage of calculation keying parameter to obtain true value.

In the case, true value T can use Tn=[n]+Kn (n:1～14, Tn: true value, [n]: read value, Kn: keying parameter) ask for.Having held the security table of this kind of keying parameter can login in the ROM in optical pickup device in advance.

For example, as security table, set in the situation of following keying parameter,

K1＝0

K2＝0

K3＝1

K4＝0

K5＝1

K6＝1

K7＝0

K8＝1

K9＝1

K10＝0

K11＝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

The corresponding relation of information bit described above and security table and true value is shown in Figure 87.

More than illustrated from information point acquired information bit, asked for the situation of true value with reference to security table, but also can according to true value, generate in 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, in the situation of T1=1, T2=0, T3=1, the available following formula of the 1st bit [1]～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]～3rd bit [3] represents.

[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 explanation is below omitted, the value of point (8)～(14) also can be asked for equally, according to this value collocation point.

And the initial value of point (1)～(3) is any random number (0 or 1).

That is,, by the value of adding information bit [1]～[3] to initial point (1)～(3) of distributing, can obtain the value of point (5)～(7) on the y direction graticule being configured in below.Identical with it, by the value of information bit [4]～[6] that add in the value in point (5)～(7), can obtain the value of point (8)～(10), also have, by the value of the information bit that adds [7]～[9], can obtain the value of point (12)～(14) on these.The value of information bit [10]～[12] that add thereon also has, if can be obtained the value of point (15)～(17).

About point (4) and (11), can subtract and calculate information bit [13] by according to the aforementioned point (8) calculating, the information bit that adds [14] is asked for respectively.

As mentioned above, in the present embodiment, according to the some configuration on graticule y (n-1), determine the some configuration on graticule yn, by repeating successively this process, can determine the configuration of all information points.

More than that imagination is used the GRID-1 of explanation above and the following concrete example of the dot pattern of GRID-2 explanation, but in following concrete example, not only can be suitable for the dot pattern computing method of GRID-1 described above or GRID-2, so long as hold the technology of information by dot pattern, can use any dot pattern.

Concrete example (1)

In following concrete example, the ink (reaction ink) of take in the region responding at optical camera elements such as cmos sensors and absorbing infrared ray or ultraviolet wavelength is typical example, with having used the example that absorbs the carbon element ink of IR wavelength to be illustrated, even if but do not conform to carbon, so long as there is the ink of these characteristics.For example, as thering is the molecular structure that does not conform to carbon, absorb the ink of ultrared characteristic, can use and connect diaphanous ink (invisible printing ink).By using this kind to connect the steady shape ink of diaphanous what is called, can will set to such an extent that be more difficult to find.

Fig. 1 uses and the carbon element ink printing point of paper with colour system, uses the non-carbon element ink of 4 looks (YMCK) to implement common printed example on this.

If adopt this concrete example, owing to being what to use with the color printing point of the identical colour system of color of paper (medium surface), thereby be with the naked eye difficult to find out this point.

In this concrete example, when paper look is pure white or almost connects in the situation of subalbous nattierblue, black) or blue or green (C) printing points if use the ash (K:, can make to have carried out common printed region on it and be difficult to find out a little that carbon content is controlled to about a few percent.Obviously, if use the invisible printing ink (trade (brand) name) that does not conform to carbon element but respond in IR wavelength region, be difficult to the naked eye know another.

In addition,, under using primary colors and containing compared with the situation of the paper of warm tones color (media), preferably use Y ink and invisible printing ink (trade (brand) name) printing points.

Carbon content in ink is preferably in 10% left and right, but, by improving the shooting performance of element, even if carbon contains, only has a few percent, also can identify with infrared optical reading device.

Concrete example (2)

This concrete example, as Fig. 2 (a) and (b), is by the printing opaque ink that further overlaps on the point in the upper printing of paper (medium surface), to make the example of naked eyes None-identified point.

Opaque ink herein refers to the ink that visible light cannot see through.That is to say, can be by the long infrared ray of ripple be passed through, the short visible light of wavelength can't pass, and realize naked eyes and can not identify, and the dot pattern that infrared ray is responded.

That is to say, on paper (medium surface) first with (Fig. 2 (a)) after carbon element ink printing point, use color or its advancing colour of this paper, or the region (Fig. 2 (b)) of any topped aforementioned point of opaque non-carbon element ink printing, and then the non-carbon element ink by 4 kinds of colors (CMYK) carries out common printed on this.

At this moment, under state shown in Fig. 2 (b), due to by the printing of opaque non-carbon element ink, point is by topped, thereby with the naked eye None-identified goes out hereunder the point of printing, but due to the penetrable aforementioned opaque non-carbon element ink layer of infrared ray, at the point of carbon element ink, be partly absorbed, infrared ray can not be from this some part reflection, and therefore available optical pickup device is accurately identified this point.

In the situation of the non-carbon element ink of White-opalescent that is used as characteristic to prepare, because opacity is original just high, even thereby some printing use with common black (K) carbon element ink, still can maintain very high disguise.

Among above explanation, for be only on paper with carbon element ink printing the overlap example of printing of opaque ink for region of point, but also can be as shown in Figure 3, first with (Fig. 3 (a)) after carbon element ink printing point, then use the whole paper surface of opaque non-carbon element ink printing.(Fig. 3 (b)).

In the case, the overall printed that adopts opaque non-carbon element ink to carry out, available random color.

At this moment, what illustrate with Fig. 2 is identical, under the state shown in Fig. 3 (b), due to by the printing of opaque non-carbon element ink, put capped, thereby the point of printing hereunder cannot with the naked eye be identified, but because infrared ray can see through aforementioned opaque non-carbon element layer, in the some part of carbon element ink, be absorbed, infrared ray cannot be from this some part reflection, therefore, available infrared optical reading device is accurately identified this point.

And the color of the carbon element 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 is all expected to have aforementioned infrared absorption effect because of the carbon that contains aforementioned a few percent.

By predetermine the color of the opaque non-carbon element ink on the upper strata of printing on whole paper, the point of Qi lower floor printing is used the carbon element ink that is similar to color with the color of aforementioned overall printed, more effectively hidden point.

Concrete example (3)

Concrete example shown in Fig. 4 is the carbon element ink printing point of using with background 4 looks (chromatic number is any) the same color of this position, color is a little sneaked among the color of periphery, more easily hidden example.

Fig. 4 (a) illustrates common single color point, and Fig. 4 (b) illustrates the point by the concentric circular regions formation of 4 kinds of colors.

This concrete example is that to adopt the net-point printing of AM print process be prerequisite, 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 concentric circles printing, prints successively Y (Huang), M (dark red), C (green grass or young crops), K (black) from lower floor.

The size of each color dot of printing, by making the diameter of the color that color range is the highest (the highest look of color range: be Y) herein diameter with dot pattern unanimously, by this color range the site amount (%) of high look be made as X0%, when the site amount of required colour is made as to x%, diameter of all kinds available following formula calculates.

Therefore, when the site amount of the Y site amount that is 70%, M the site amount that is 50%, C the site amount that is 30%, K is 20%, diameter of all kinds respectively following (with reference to Fig. 5 (a)).

In addition K (black) composition is overlapped respectively in the situation that on the various compositions of C, M, Y, diameter of all kinds is (with reference to Fig. 5 (d)) as follows.Can, by K composition (black content) is overlapped on the various compositions of other C, M, Y, reduce the use chromatic number of ink like this.

Wish further to reduce in the situation of chromatic number, among this printing, dominant by certain color, or wish certain color obvious (object look), only this object look also can be reduced to the chromatic number that forms point for point.

In addition, if adopt this concrete example, a little easily hidden owing to not only making, simultaneously not only with the K performance dot pattern of carbon element ink, can prevent and outside the K of the non-carbon element ink because using on common printed site, sneak into the color blackening that the K of carbon element ink produces.

Concrete example (4)

Concrete example shown in Fig. 6 and Fig. 7 illustrates by color separation processing and only extracts know-why a little.

In this concrete example, illustrate when common printed and do not use black (K), only use CMY ink to carry out, the recognition methods while only using black (K) performance to form the point of dot pattern.

At this moment, the ink that uses in the printing of common printed and point is so long as ink that can optical identification in visible light region, and any ink all can.

After the coloured image input RGB picture buffer of having used the camera head of CMOS imaging apparatus, CCD imaging apparatus etc. to take the paper (medium surface) that adopts this kind of method printing, carry out color separation processing in optical pickup device.Fig. 6 (a) illustrates RGB composition ratio of all kinds now.

Generally speaking, among the CMOS of optically read element etc., while reading, there is the characteristic that more or less.This be because, color component deflection is of the same colour, when influence power is large, other color is also subject to its index, or inconsistency also has impact during fabrication, for example, the result reading is often the image (with reference to Fig. 6 (a)) of whole general green grass or young crops.If this specific character image is implemented to dot pattern identification, the in the situation that of color separation processing, due to the existence of cyan composition, the point of K ink (black) is often difficult to read as black, occurs reading error.Therefore, when reading, revised.

That is, from the image reading, retrieve the pixel of the result minimum that adds of RGB.So, the pixel of the result minimum that adds of RGB is a little certainly.Now, in RGB, occur only having in the inconsistent situation that B value is high, be knownly corrected for the image that cyan is strong.Therefore using the pixel of the result minimum that adds of RGB rgb value separately 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 correction.

Then as previously mentioned, for example, to revised image (Fig. 6 (d)), get the maximum of RGB data and the mean value of minimum of a value of each pixel, the width of when Fig. 6 (f) (for example) compression aforementioned areas α when high by the tonal gradation at this mean value, when aforementioned tonal gradation is low, (for example Fig. 6 (e)) widens the width of aforementioned areas α, and the identification of the dot pattern that can make to adopt K ink (black) in visible light region is more easy.

Among each pixel, subtract while calculate processing aforementioned RGB composition, become in the situation of negative value and be made as without exception 0.And the extraction of this RGB Minimum Area also calculates correction a reference value after a plurality of samplings of more available pixels.

In this concrete example, in the situation that print dark netrual colour (grey) with CMY outside point, due to can not with the some difference that adopts color separation processing, thereby identification point only.But, if printing is only light netrual colour (grey), because this part is not as some identification, thereby no problem.

Therefore, during printing, need not dark-greyly be its prerequisite, if but adopt this concrete example, by color separation processing, can identify a little.

Because this concrete example does not need special infrared radiation function and filter function, thereby can from the photographs of the shootings such as the digital camera function with additional existing digital camera, mobile telephone terminal and WEB camera, identify a little.

If conclude above processing procedure, as long as implement following process in optical pickup device.

1) first calculate the highest light of RGB of each pixel and the mean value X of the grade of low light (maximum 100%).

2) then, according to the difference of the highest light of RGB and low light, whether be greater than certain value α, judge that this object is only no in tonal gradation (judgement gray scale).

For example establish α=-1/10X+10.

Herein 10 are correction factors, in situation due to X infinite approach 100%, be judged to be tonal gradation 100 (white), thus no problem, but in order not occur decision errors (being judged to be white error in low region) in the situation that tonal gradation is low, implement+10 and revise.

3), in the situation between α > greatest level-the lowest class, X is set as to the grade of tonal gradation.

4), in the situation between α < greatest level-the lowest class, tonal gradation is set as to 100% (white).

5) according to tonal gradation real-time image processing, after binarization, be judged to be a little.

Correction factor is set as to 10 herein, but obviously also can be set as 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 that the point of dot pattern is doubled as to the example into the black site of printing.

Figure 10 is among AM print process, during using site as the point of dot pattern, when the configuration logic of figure is GRID-1, left figure is the original image of C, M, Y, right figure extracts a part of K composition (black content) from C, M, Y, and dot pattern is doubled as to the enlarged drawing into the printing surface of site.Among this figure, as the K carbon element ink printing of point.Owing to only extracting the K composition (black content) of the site amount being equivalent to a little from original image C, M, Y, 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 in common component, can be used as after the minimum site amount a little reading using this as K composition collocation point.

Figure 11 is among AM print process, during using site as the point of dot pattern, when the configuration logic of figure is GRID-1, left figure is the original image of C, M, Y, right figure all extracts K composition (black content) from C, M, Y, and dot pattern is doubled as to the enlarged drawing into the printing surface of the site of K.Among this figure, as the K of point, with carbon element ink or non-carbon element ink printing, take with the color seperation identification point of explanation in concrete example (4) is precondition.

Figure 12 is among AM print process, point using site as dot pattern is, the configuration logic of figure is that GRID-1 is, left figure is the original image of C, M, Y, and right figure extracts enlarged drawing dot pattern being doubled as after the K composition (black content) of image printing coideal as the printing surface of the site of K1 and K2 from original image C, M, Y.Among this figure, non-carbon element ink printing for K1, K2 carbon element ink printing, K1 is the site doubling as dot pattern, K2 is used in and in the region of this K1, can be used as the minimum site amount a little the reading printing that overlaps.Therefore, the point of K2 is only less than K1, can be used as the identification point of the free degree.

Figure 13 is among AM print process, point using site as dot pattern is, when the configuration logic of figure is GRID-2, left figure is the original image of C, M, Y, and right figure doubles as the enlarged drawing into net-point printing face by dot pattern extract a part of K composition (black content) from C, M, Y after.Among this figure, as the K carbon element ink printing of point.Owing to only extracting the K composition (black content) be equivalent to site amount from original image, thereby there is K composition (black content) in the C of right figure, M, Y.

Figure 14 is among AM print process, during using site as the point of dot pattern, when the configuration logic of figure is GRID-2, left figure is the original image of C, M, Y, right figure extracts whole K compositions (black content) from C, M, Y, with the site of K, doubles as the enlarged drawing into the printing surface of dot pattern.Among this figure, as carbon element ink or the non-carbon element ink printing for K of point, take with the color seperation identification point of explanation in concrete example (4) is precondition.

Figure 15 is among AM print process, during using site as the point of dot pattern, when the configuration logic of figure is GRID-1, left figure is the original image of C, M, Y, and right figure doubles as the printing surface enlarged drawing into the site of K1 and K2 by dot pattern extract the desirable K composition (black content) of image printing from original image C, M, Y after.Among this figure, non-carbon element ink printing for K1, K2 carbon element ink printing, K1 is the site doubling as dot pattern, K2 is used in and in the region of this K1, can be used as the minimum site amount a little the reading printing that overlaps.Therefore, the point of K2 is only less than K1, can be used as the identification point of the free degree.

As mentioned above, the point of this concrete example is by doubling as site but depart from the position of former site, with its offset manner definition information.

That is to say, dot pattern is that point is configured in to (grid point) that the intersection point of graticule is principle originally, but in this concrete example, is collocation point in the grid point every, and all the other are as the information point printing that departs from grid point.

About the definition of this information point, due to front, illustrated, thereby the description thereof will be omitted herein.

If adopt this concrete example, as above-mentioned, owing to the substantive site existing on printing surface can being doubled as point, thereby with the naked eye identification point is almost unable to handle.

For can being all suitable for to depart from the dot pattern of grid point definition information.

In addition, the inventor etc. recognize in order to read with infrared optics reading device, in situation with the point of K carbon element ink printing dot pattern, because the some position of the K site of the non-carbon element ink of printing is different, if thereby repeat print these on paper (medium surface), finally there will be blackening, if but adopt the present invention, owing to dot pattern being doubled as to the site into K, only in common printed, carry out 4 look printings, thereby there is blackening can be when in addition with K ink printing dot pattern, can make printing surface keep beauty.

In situation about the black of site (K) being doubled as into point, because needs make a little to depart from grid point, large when therefore the possibility of some connection adjacent one another are is than common site.Common site often more than 50% is connecting.Therefore, in this concrete example, need site amount to be adapted to maximum 20～25% left and right.But, if being made to high-precision image, the shape of point processes, even if site amount still can be identified over 50%.

Fig. 8 illustrates in this concrete example point is printed as to foursquare situation, and Fig. 9 illustrates the conglobate situation of printing.

Want in the situation that there is no black (K) colour content completely, or Detection Point in few situation, preferably with site minimum a few percent (if printing precision is low, percentage should be larger) that is not less than of amount, show a little.

In the situation that adopting infrared radiation mode to be applicable to this concrete example, also can, by using K carbon element ink in the printing at point, as shown in figure 16, point be adapted to the size of being convenient to identify and print afterwards.

Among Figure 16 (a), (b), by account for 50% K composition (black content) 30% as this figure (a) ', (b) ' as shown in, except CMY, by K is reduced to 30%, prevent that adjacent point from contacting.Among this figure, in order describing, an interval to be made as to equalization, but as aforementioned, to double as at the same time in the situation into site and information point, obviously can in this configuration, produce deviation.Figure 17 is the figure of the dot pattern of brief description GRID-1, and it overlaps and has configured the information point of black ring shape on the site of square configuration.

Concrete example (6)

This concrete example by arranging shaded portions in 1 printing images, and making this cover shape becomes discernible example.

In this concrete example, by region being divided into regulation shape to the part of using non-carbon element ink CMYK to print in image, and the part of using carbon element ink to print, with infrared mode, read with the word of carbon element ink printing and pattern, various code.

Specifically as shown in figure 18, in image, set and wish the hidden shape of covering, then as shown in Figure 19 (a), by the part outside non-carbon element ink printing shaded portions.

Then as shown in Figure 19 (b), with carbon element ink printing shaded portions.

So, complete the image shown in Figure 19 (c).At this moment, because how much different the ink containing carbon element is with the ink quality characteristic that does not conform to carbon element, thereby there is inharmonious sense in order to prevent from detecting by an unaided eye, preferably shaded portions or non-shaded portions are carried out to ink colors correction, to do not see the printing of covering border.Obviously also can be without carbon element ink, but use the ink that has added invisible printing ink.

If the image shown in this Figure 19 (c) is carried out to infrared radiation, with infrared optical reading device, read its reverberation, owing to only having the shaded portions with carbon element ink printing to absorb infrared ray, thereby can identify the occlusion image region shown in Figure 18.What this shaded areas adopted in this concrete example (6) is the shape of the capitalization A of ABC, but this region also can adopt the shape of other word, sign, figure.In addition the dot pattern printing that, the printing of this shaded areas also illustrates in available other concrete example.

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 only, by the part of point, only the pixel portion that forms point is used to the CMY of homochromy carbon element ink, remainder is used non-carbon element ink, utilizes infrared radiation to get final product identification point.

But among the point of formation dot pattern, as shown in Figure 20 (b), in the absence of colouring information, need to exchange color or distribute the homochromy of periphery to pixel with the pixel of periphery as shown in figure 21, with carbon element ink, generate the shape that can be used as an identification.

In addition, among the pixel of periphery, do not have completely in the situation of colouring information, need carry out printing points by generating the color approximate with paper with carbon element ink.

In the above embodiment, the situation while using 4 looks (CMYK) carbon element ink has been described, but also can be identical with concrete example (3), omit mass colour (K), with CMY3 look carbon element, show.That is to say, for each pixel that forms point, remove K composition from CMYK, this one-tenth component is increased to CMY upper, the color range that improves CMY is carried out the color of adjusting point.Can with CMY3 look carbon element ink, show a little without black (K) like this, thereby chromatic number is reduced.In pixel, do not have in the situation of colouring information, can exchange color with the pixel of periphery, or distribute the homochromy of periphery to pixel, with carbon element ink, generate the shape that can be used as an identification.

In addition, among FM screen mode of printing, also available point doubles as black (K), and the periphery of point is only existing with CMY tri-color tables.

That is to say, utilize the domination area of point, i.e. (printing area/counting), the CMY that the common color range of each color range of contained pixel CMY separately in the region of 1 point (maximum 100%) 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 of the point that forms available black performance.By configure twist black (K) pixel from the center of collocation point on this, can form point (with reference to Figure 22).

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, due to needn't be with carbon element ink and the non-carbon element ink K ink (black) of repeating print, thereby can suppress the blackening of printing surface.

But in this concrete example, on paper, in the domination region of the point of (on medium surface), do not have completely in the situation of black, need to use black (K) the performance point of the minimum pixel number that can be used as an identification.
