Description
Technical field
The invention belongs to a kind of code generating method that is suitable for Internet access through mobile phone photograph download multi-medium data in the field of wireless communication.
Background technology
By the end of the year 2008, cellphone subscriber's the signatory quantity only sum of China, three countries of the India and the U.S. just surpasses 1,000,000,000 according to international electrical communication Colaesce (ITU) statistics.The quantity of mobile phone production is that straight line rises always, so the value-added services businesses of mobile phone also are the focuses that attracts people's attention.Here enlarge important techniques means of mobile phone value-added service, solve the Web portal problem of mobile phone exactly, promptly how simply to make the mobile phone direct interconnection network.
Solve the Web portal problem of mobile phone, just there was the patent application that is entitled as " information service (feelings Reported provides サ one PVC ス) is provided " (patent documentation 1) in Japan as far back as 2000, proposed directly to take two-dimensional bar code with the camera function of mobile phone, the motion that can directly surf the Net.This motion extremely mobile phone manufacturer must be paid close attention to, and to the mobile phone of selling in Japan in 2005, has almost all carried and has taken the directly function of online of two-dimensional bar code.And only within half a year, mobile phone is taken two-dimensional bar code and is directly surfed the Net this function just by universal.
After this, the technology of taking the direct online of two-dimensional bar code with regard to mobile phone has had some improved patent applications again, for example Japanese famous Sharp Corp also applied for being entitled as in 2007: the patented invention content of " mobile phone terminal device and information fetch program thereof (take Bands window machine and び Qing Reported Reading and get プ ロ グ ラ system) " (patent documentation 2), it is simpler to have proposed operation, makes the higher method of discrimination of identification two-dimensional bar code.But, since two-dimensional bar code self just exist not attractive in appearance, can not directly pass through the certain commercial content of visual expression, do not have problems such as aesthstic intention.Therefore, although mobile phone can't resolve the root problem of two-dimensional bar code to the improving constantly of the recognition technology of two-dimensional bar code.
Recently, the user is not attractive in appearance at two-dimensional bar code, can not the certain problems such as commercial content of direct representation, can proposition directly become the trade mark of commodity or enterprise into two-dimensional bar code, for adapting to user's requirement, Japan in 2007 again the someone propose: the patent application of " two-dimensional bar code (the ロ go pays I Quadratic Finite Element コ one De) that has trade mark " (patent documentation 3) makes mobile phone take login technique and has promoted a grade.
But, it only is a remedial, at first this scheme is the pattern of stack trade mark on the dot matrix of two-dimensional bar code, because position that the dot matrix of two-dimensional bar code distributes and printing area are to occur at random according to the difference of code value, therefore can cause the serious distortion of pictorial trademark, the intention that influence is aesthstic.
Have again, this scheme also proposes to absorb the two-dimensional bar code that ultrared black ink prints off with having, again on two-dimensional bar code, print trade mark with infrared ray transparent color printing ink, change the camera lens of mobile phone photograph into the infrared ray camera lens, like this, even be printed with trade mark, but mobile phone can only be taken pictures out to the image of the two-dimensional bar code of infrared ray absorbing, therefore can solve the problem of trade mark and two-dimensional bar code coexistence.
But according to a kind of like this scheme, the mobile phone photograph two-dimensional bar code just can not be put together with common mobile phone camera function, thereby has improved the cost of manufacture of mobile phone, has influenced popularizing of Internet access through mobile phone photograph.In addition, print trade mark with specialty inks, also cause the raising of printing cost, its result also is unfavorable for popularizing of this technology.

Fig. 7 is that the code with Fig. 4 is embedded to the example in the trade mark.As shown in Figure 7,701 is the information dot matrix, and 702 are the location dot matrix, and 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 is secondary perpendicular positioning lattice array.The dot matrix of the white of Fig. 4 code is kept, and the black part overlaps with the pattern of trade mark, image or figure etc., and can obtain can the direct representation trade mark, macroscopical code of the pattern of image or figure etc.Be the pattern of expression trade mark, image or figure etc. that more can be true to nature, white dot matrix part also can same trade mark, the pattern of image or figure etc. overlaps, and just the gray value minimum gradation value that is less than general pattern gets final product.
Fig. 8 is that the code with Fig. 6 is embedded to the example in the trade mark.As shown in Figure 8,801 is the information dot matrix, and 802 are the location dot matrix, and 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 is secondary perpendicular positioning lattice array.The dot matrix of the white of Fig. 6 code is kept, and the black part overlaps with the pattern of trade mark, image or figure etc., and can obtain can the direct representation trade mark, macroscopical code of the pattern of image or figure etc.Be the pattern of expression trade mark, image or figure etc. that more can be true to nature, white dot matrix part also can same trade mark, the pattern of image or figure etc. overlaps, and just the gray value minimum gradation value that is less than general pattern gets final product.
Fig. 9 is that the code with Fig. 4 is embedded to the example in the image.The dot matrix of the white of Fig. 4 code is extracted out, be transformed into yellow dot matrix.The yellow color component in the pattern of trade mark, image or figure etc. is removed again, overlapped with yellow dot matrix, can obtain can the direct representation trade mark, macroscopical code of the pattern of image or figure etc.

Below, introduce the principle and the structure of the microcosmic code that the present invention proposes.Be defined as the microcosmic code, consider that exactly the lattice dimensions of its code is below the 0.1mm at the invisible numerical value of the naked eyes that Rayleigh criterion calculated generally.
At first, two-dimentional macroscopical code that Fig. 3 provides is to be based upon the code means that viewpoint realized that printing area is strengthened.If from opposite viewpoint, promptly the minimized angle of printing area is set out, and can draw binary system microcosmic code form shown in Figure 12.
(a) of Figure 13 is code " 1 ", (b) is code " 0 ".On recorded information be by: it is " 1 " that information point is arranged, and no information point is " 0 ".This phenomenon can be thought the difference realization information record that occurs by printing.On physics, also may be 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.
Macroscopical code of the two dimension that Fig. 4 provides also is to be based upon the code means that viewpoint realized that printing area is strengthened.Also can be from opposite viewpoint, promptly the minimized angle of printing area is set out, and can draw binary system microcosmic code form shown in Figure 13.
(a) of Figure 14 is code " 0 ", (b) is code " 1 ", (c) is code " 2 ", (d) is code " 3 ".Be by the different directly records in the position of dot matrix bit information more than on recorded information.This phenomenon not only can be thought by the difference realization information record of printing dot matrix state, also can think the geometry phenomenon by different lattice positions or different shape realization information record.On physics, also may be interpreted as the phase modulated outcome record information of the dot matrix in the grid that is to use two dimensional image.
In like manner, two-dimentional macroscopical code that Fig. 5 provides also is to be based upon the code means that viewpoint realized that printing area is strengthened.Same from opposite viewpoint, promptly the minimized angle of printing area is set out, and can draw binary system microcosmic code form shown in Figure 14.
(a) of Figure 15 is code value " 0 ", (b) is code value " 1 ", (c) is code value " 2 ", (d) is code value " 3 ", (e) is code value " 4 ", (f) is code value " 5 ".Be by the different directly records in the position of dot matrix bit information more than on recorded information.This phenomenon not only can be thought the difference realization information record that occurs by printing, also can think the geometry phenomenon by different lattice positions or different shape realization information record.On physics, also may be interpreted as the phase modulated outcome record information of the dot matrix in the grid that is to use two dimensional image.
And two-dimentional macroscopical code that Fig. 6 provides also is to be based upon the code means that viewpoint realized that printing area is strengthened.Same from opposite viewpoint, promptly the minimized angle of printing area is set out, and can draw binary system microcosmic code form shown in Figure 15.
(a) of Figure 16 is code value " 0 ", (b) is code value " 1 ", (c) is code value " 2 ", (d) being code value " 3 ", (e) is code value " 4 ", (f) is code value " 5 ", (g) being code value " 6 ", (h) is code value " 7 ", (i) is the location dot matrix.Identical with above-mentioned principle, be by the different directly records in the position of dot matrix bit information more than on recorded information.This phenomenon not only can be thought the difference realization information record that occurs by printing, also can think the geometry phenomenon by different lattice positions or different shape realization information record.On physics, also may be interpreted as the phase modulated outcome record information of the dot matrix in the grid that is to use two dimensional image.
The form according to matrix of the dot matrix that a plurality of above-mentioned Figure 13-16 are provided is arranged, and can constitute one group of information module.
The dot matrix image that at first defines the Two dimensional Distribution of planographic is:
[formula 1]
ζ＝ψ(x，y)
Because image ζ is the image of binaryzation, so 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 must draw a code value in given coordinate system.Figure 16 is the example that 4*4 the such microcosmic dot matrix of Figure 15 is constituted a code.
As shown in figure 17, for example establish S
11=0, S
12=0, S
14=2, S
15=2, S
21=4, S
22=4, S

42=0, S
44=2, S
45=2, S
51=4, S
52=4, S
54=6, S
55=6.Then code value is:

It is n*m that the 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.The microcosmic dot matrix can print with the CMYK random color, also can use infrared ray, ultraviolet ray, or this journey ink printing.Also the image lattice of available electron form is represented.
The distribution of miniature dot matrix can be the distribution of two-dimension non linearity, establishes;
[formula 3]
x
I+1-x
i=κ P (τ) κ is an arbitrary integer
I=1,2 ..., n, P (τ)=O-1 is a random function
y
J+1-y
j=ν P (ε) ν is an arbitrary integer
J=1,2 ..., m, P (ε)=O-1 is a random function
x
1=0 and y
1=0
Then the microcosmic dot matrix can be showed by the form that the two-dimension non linearity dot matrix distributes, promptly
[formula 4]
ξ＝ψ{κP(τ)，νP(ε)}
Therefore each and every one dot matrix of the microcosmic code of the form performance that above-mentioned two-dimension non linearity dot matrix distributes does not have certain code value as the information module owing to be random distribution.If but provide a benchmark dot matrix, just can draw a fixing code value with any distance yardstick that comprises Euclidean distance.
The microcosmic code that the form that is distributed by the two-dimension non linearity dot matrix shows can have special effect under many circumstances.
Figure 18 is the location mode of cross benchmark dot matrix.As shown in figure 18, the benchmark dot matrix is a cross, and the information dot matrix is distributed on 4 angles of benchmark dot matrix, and in one group of information module, cross benchmark dot matrix can be formed by one, also can be made up of a plurality of.The benchmark dot matrix also can be made up of other any forms.
The benchmark dot matrix can print with any one the above color in CMYK four looks, can represent with any one the above color in RGB three looks, 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 for being printed with the part of microcosmic code, and 1902 is the holographic false proof image section.The image that is printed with the part of microcosmic code uses microcosmic code reading device to carry out code and reads, and the holographic false proof image section can directly with the naked eye distinguish the true from the false.Carrying out the characteristics that the true and false distinguishes with reading device is to genuine/counterfeit discriminating precision height, though it is relatively more directly perceived with the naked eye to distinguish the true from the false, the precision that distinguishes the true from the false is low.This two kinds of methods of discerning the false from the genuine are combined, merged the characteristics of two kinds of methods of discerning the false from the genuine.
Figure 20 represents the characteristic that had in RGB color and the mutual conversion of CMYK color.As shown in figure 20: in the countless colors of forming by CMYK, always can find more than one color, this color printing is on print media, if take pictures or scan by imageing sensor, the RGB image that is constituted, this RGB image is carried out CMYK again divide version, each value of resulting CMYK is not equal to each value of initial CMYK.Utilize that this characteristic is above-mentioned in addition can to realize digitized anti-counterfeit printing for the formation characteristic of microcosmic code.
Advantageous effect of the present invention is:
1. the invention provides a kind of mobile phone and just can directly surf the Net by directly take pictures trade mark or pattern of picture taking lens, but and the formation scheme of macroscopical code of downloading data.

Can realize multimedia to the printed matter that is embedded with arbitrarily information. Can be applied to the to go sightseeing guide of map, the network selling of product sample, the judgement of true and false commodity.
3. the dot matrix that the invention allows for the two-dimension non linearity space distributes, and has in the situation that does not have the benchmark dot matrix, does not have certain code value. And must obtain a definite code value behind the given benchmark dot matrix, this acquires a special sense in information security field.
4. what the present invention proposed carries out the true and false discriminating of name brands with mobile phone, can simply judge by naked eyes, by can accurately distinguishing true from false by mobile phone.
5. macroscopical code of the present invention's proposition has maximum printing area, and pictorial trademark directly is printed on the code. It is long-pending that the microcosmic code has the ND smallest point front of naked eyes, is embedded in the printing images, do not affect picture quality.
