Octal system information shown in Fig. 6 is grandThe information recording rate of seeing code is 0.33, and printing area rate is 8/9. Printing area rate is very high, but equally believes with Fig. 5Breath recording ratio declines a lot. Therefore,, from the situation of information recording rate and the consideration of printing area rate, can adopt Fig. 4Code form, can consider the code form of Fig. 6 if emphasis is considered the quality of image.
The code of Fig. 4 is embedded to the example in trade mark by Fig. 7. As shown in Figure 7,701 is information dot matrix, and 702 is locationDot matrix, 703 is that main horizontal location dot matrix is capable, and 704 is main perpendicular positioning lattice array, and 705 is that secondary horizontal location dot matrix is capable, and 706 areSecondary perpendicular positioning lattice array. The white dot matrix of Fig. 4 code is retained to the pattern of black part and trade mark, image or figure etc.Overlap, can obtain can direct representation trade mark, macroscopical code of the pattern of image or figure etc. For table that more can be true to natureShow the pattern of trade mark, image or figure etc., white dot matrix part also can same trade mark, the pattern of image or figure etc. overlaps, justGray value is less than the minimum gradation value of general pattern.
The code of Fig. 6 is embedded to the example in trade mark by Fig. 8. As shown in Figure 8,801 is information dot matrix, and 802 is locationDot matrix, 803 is that main horizontal location dot matrix is capable, and 804 is main perpendicular positioning lattice array, and 805 is that secondary horizontal location dot matrix is capable, and 806 areSecondary perpendicular positioning lattice array. The white dot matrix of Fig. 6 code is retained to the pattern of black part and trade mark, image or figure etc.Overlap, can obtain can direct representation trade mark, macroscopical code of the pattern of image or figure etc. For table that more can be true to natureShow the pattern of trade mark, image or figure etc., white dot matrix part also can same trade mark, the pattern of image or figure etc. overlaps, justGray value is less than the minimum gradation value of general pattern.
The code of Fig. 4 is embedded to the example in image by Fig. 9. The white dot matrix of Fig. 4 code is extracted out, be transformed into HuangColor dot battle array. Again the yellow color component in the pattern of trade mark, image or figure etc. is removed, then is overlapped with yellow dot matrix,Obtaining can direct representation trade mark, macroscopical code of the pattern of image or figure etc.
The code of Fig. 6 is embedded to the example in image by Figure 10. The white dot matrix of Fig. 6 code is extracted out, be transformed intoYellow is the code of the Y color dot matrix in CMYK tetra-looks. Again the yellow color component in the pattern of trade mark, image or figure etc. is goneFall, then overlap with yellow dot matrix, can obtain can direct representation trade mark, the macroscopic view generation of the pattern of image or figure etc.Code. In like manner, the white dot matrix of Fig. 6 code is extracted out, being transformed into blueness is the code of the C color dot matrix in CMYK tetra-looks, alsoThe white dot matrix of Fig. 6 code can be extracted out, being transformed into pink is the code of the M color dot matrix in CMYK tetra-looks, also canSo that the white dot matrix of Fig. 6 code is extracted out, being transformed into black is the code of the K color dot matrix in CMYK tetra-looks, now, and mobile phoneCamera also can add infrared ray optical filtering camera lens, directly use infrared illumination, receive ultrared black and white by cameraImage, carries out code identification and can improve processing speed and can be used as the application in commodity counterfeit prevention field.

Introduce principle and the structure of the microcosmic code of the present invention's proposition below. Be defined as microcosmic code, consider exactly its generationThe invisible numerical value of naked eyes that the size of the point of code generally calculates in Rayleigh criterion is below 0.1mm.
First, the two dimension macroscopic view code that Fig. 3 provides, is to be based upon the viewpoint that makes as far as possible printing area strengthen to realizeCode means. If from contrary viewpoint, the minimized angle of printing area is set out, and can draw the binary system shown in Figure 12Microcosmic code form.
(a) of Figure 13 is code " 1 ", is (b) code " 0 ". In recorded information, be to pass through: having information point is " 1 ", without letterBreath point is " 0 ". This phenomenon can think that the difference that occurs by printing realizes information recording. In physics, also can separateBe interpreted as the saltus step of a pulse on two dimensional surface. Utilize the distribution of different frequency to realize recording of information in other words conj.or perhaps.
Two-dimentional macroscopical code that Fig. 4 provides is to be also based upon the viewpoint that makes as far as possible printing area strengthen to realizeCode means. Also can be from contrary viewpoint, the minimized angle of printing area is set out, and can draw the binary system shown in Figure 13Microcosmic code form.
(a) of Figure 14 is code " 0 ", is (b) code " 1 ", is (c) code " 2 ", is (d) code " 3 ". In recorded informationOn be the different directly records in the position bit informations more than by dot matrix. This phenomenon not only can think to pass through printing pointsThe difference of battle array state realizes information recording, also can think to realize information note by different lattice positions or different shapesThe geometry phenomenon of record. In physics, also may be interpreted as is the phase-modulation knot that uses the dot matrix in the grid of two dimensional imageFruit recorded information.
In like manner, the two dimension macroscopic view code that Fig. 5 provides, is to be also based upon the viewpoint that makes as far as possible printing area strengthen to realizeCode means. Same from contrary viewpoint, the minimized angle of printing area is set out, and can show that two shown in Figure 14 entersMicrocosmic code form processed.
(a) of Figure 15 is code value " 0 ", is (b) code value " 1 ", is (c) code value " 2 ", is (d) code value " 3 ", (e)For code value " 4 ", (f) be code value " 5 ". It in recorded information, is the different directly records in the position bit more than by dot matrixInformation. This phenomenon not only can think that the difference occurring by printing realizes information recording, also can think by notSame lattice position or different shapes realize the geometry phenomenon of information recording. In physics, also may be interpreted as is to useThe phase-modulation outcome record information of the dot matrix in the grid of two dimensional image.
And the two dimension macroscopic view code that Fig. 6 provides, is to be also based upon the viewpoint that makes as far as possible printing area strengthen to realizeCode means. Same from contrary viewpoint, the minimized angle of printing area is set out, and can show that two shown in Figure 15 entersMicrocosmic code form processed.
(a) of Figure 16 is code value " 0 ", is (b) code value " 1 ", is (c) code value " 2 ", is (d) code value " 3 ", (e)For code value " 4 ", (f) be code value " 5 ", be (g) code value " 6 ", be (h) code value " 7 ", be (i) location dot matrix. With above-mentionedPrinciple is identical, is the different directly records in the position bit information more than by dot matrix in recorded information. This phenomenon not onlyCan think that the difference occurring by printing realizes information recording, also can think by different lattice positions or differenceShape realize the geometry phenomenon of information recording. In physics, also may be interpreted as is to use in the grid of two dimensional imageThe phase-modulation outcome record information of dot matrix.
The form according to matrix of the dot matrix that a plurality of above-mentioned Figure 13-16 are provided is arranged, and can form one group of informationModule.
First the dot matrix image that defines the Two dimensional Distribution of planographic is:
[formula 1]
ζ＝ψ(x，y)
Due to the image that image ζ is binaryzation, therefore the value of ζ is " 0 " or " 1 ".
Suppose that x and y value are nonrandomnesses, a plurality of microcosmic dot matrix as Figure 12-15 are in given coordinate systemMust draw a code value. Figure 16 is the example that 4*4 the such microcosmic dot matrix of Figure 15 is formed to a code.
As shown in figure 17, for example establish S11＝0，S12＝0，S14＝2，S15＝2，S21＝4，S22＝4，S24＝6，S25＝6，S41＝0，S42＝0，S44＝2，S45＝2，S51＝4，S52＝4，S54＝6，S55=6. Code value is:
[formula 2]

It is n*m that microcosmic dot matrix can be made up of with the matrix of a vertical m dot matrix a horizontal n dot matrix, and n and m can be numerals 1,Or 2, even can arrive infinite. Microcosmic dot matrix can print with CMYK random color, also can use infrared ray, ultraviolet ray,Or this journey ink printing. Also the image lattice of available electron form represents.
The distribution of miniature dot matrix can be the distribution of two-dimension non linearity, establishes;
[formula 3]
xi+1-xi=κ P (τ) κ is arbitrary integer
I=1,2 ..., n, P (τ)=0-1 is random function
yj+1-yj=ν P (ε) ν is arbitrary integer
J=1,2 ..., m, P (ε)=0-1 is random function
x1=0 and y1＝0
The form that microcosmic dot matrix can be distributed by two-dimension non linearity dot matrix shows,
[formula 4]
ξ＝ψ{κP(τ)，νP(ε)}
Each and every one dot matrix of the microcosmic code of the form performance that above-mentioned two-dimension non linearity dot matrix distributes is owing to being random distribution, because ofThis does not have certain code value as information module. If there is appointing including Euclidean distance but provide oneThe benchmark dot matrix of meaning distance scale, just can draw a fixing code value.
The microcosmic code of the form performance being distributed by two-dimension non linearity dot matrix can have special answering under many circumstancesUse effect.
Figure 18 is the location mode of cross benchmark dot matrix. As shown in figure 18, benchmark dot matrix is cross, and information dot matrix dividesCloth is on 4 angles of benchmark dot matrix, and in one group of information module, cross benchmark dot matrix can form by one, also can be by multipleSeveral compositions. Benchmark dot matrix also can be made up of other any forms.
Benchmark dot matrix can print by any one the above color in CMYK tetra-looks, can use appointing in RGB tri-looksMore than one colors of anticipating represent, also can use infrared ray, ultraviolet color, or magnetic ink prints or represents.
Figure 19 is the anti-false trademark that adopts microcosmic code technique and holographic technique to make. As shown in figure 19; 1901 is printingHave the part of microcosmic code, 1902 is holographic false proof image section. The image that is printed with the part of microcosmic code uses microcosmic generationCode reading device carries out code and reads, and holographic false proof image section can directly with the naked eye distinguish the true from the false. Carry out very with reading deviceThe feature that puppet is distinguished is high to genuine/counterfeit discriminating precision, although it is more directly perceived with the naked eye to distinguish the true from the false, and the precision distinguishing the true from the falseLow. This two kinds of methods of discerning the false from the genuine are combined, merged the feature of two kinds of methods of discerning the false from the genuine.
Figure 20 represents the characteristic that RGB color and CMYK color have in mutually converting. As shown in figure 20; By CMYK groupIn the countless colors that become, always can find more than one color, this color printing is on print media, if pass through imageSensor is taken pictures or is scanned, and this RGB image is carried out CMYK point of version by the RGB image forming again, and the CMYK's obtaining is eachIndividual value, is not equal to each value of initial CMYK. Utilize this characteristic in addition the above-mentioned formation characteristic for microcosmic code can realizeDigitized anti-counterfeit printing.
