Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further described, but embodiment of the present invention is illustrative, rather than determinate.
The present invention is at first at the positional information that comprises printed images, and sequence information, content information propose the novel code of description method in the information of the interior printed images described feature.
Below in the present embodiment, described pixel is the least unit of composing images, the site is the pairing screen least unit of pixel with the least unit of composing images, the least unit point that the site can be printed by printing equipment is formed with the dot matrix that necessarily is regularly arranged into, and half-tone screen code is made up of the site.
The definition of the sign half-tone screen code described in the present invention: independently exist with certain code form, maximum similar degree is less than 3/4 between code, dot matrix with single gray scale distributes, have the self checking characteristics, code is the form appearance with the screen site, naked eyes are difficult for discovering, and are printed on the common color image as a kind of printing screen, a kind of code of imbedding at the printed images information of carrying out that the quality of image can not be reduced.
Sign property half-tone screen code is different from bar shaped half-tone screen code and two-dimentional half-tone screen code, the former is a self-existent code, bar codes or two-dimensional bar code as a large amount of uses at present all belong to sign property code, as long as this code is identified, just can carry out an operation.And the latter just carries out an operation after entire image or whole page or leaf printed matter are discerned.Both are very approaching again aspect a lot.
The important sign that sign property half-tone screen code is different from two-dimensional bar code is: can be printed on the printed images, and to reach together with image co-registration, i.e. the effect that the information of carrying out is imbedded under the prerequisite that the quality of image can not reduce.Sign property half-tone screen code has the homogeneous gray scale, can constitute the effect of printing screen.In addition, sign property half-tone screen code is different from another important sign of two-dimensional bar code and is: maximum similar degree is less than the ordinary two dimensional bar code between code, and antijamming capability is strong; Need not special-purpose position detection mark but realize by the formation of self code; Can carry out error correction by the rule of code, need not complicated error correction computing.
The definition of location dot matrix, with a kind of spread pattern that is different from the code dot matrix, when distortion appearred in print media, the dot matrix that is printed on each lattice position of sign half-tone screen code on the print media as quantification was called the location dot matrix.
The minimized notion of maximum similar degree between the half-tone screen code code; The implication of similar degree is exactly the similarity degree between code between so-called code, and the big more representative of its value is similar more, and resolution is low more, discerns difficult more; Otherwise similar degree is more little between code, and resolution is high more, and it is easy more to discern.
In half-tone screen code, establish S
kFor message code, n are that code is long, when m is the quantity of code, maximum similar degree A between described half-tone screen code

Here, the present invention provides between code maximum similar degree at an example below 1/2;
Maximum similar degree also has various forms in not only this a kind of form below 1/2 between the code that present embodiment proposes.Also be not only 4 code, also have 8,16,24,32 even up to the code of N position.
Maximum similar degree in the effect intuitively of the code 1/2 below is: to have the code value of figure place over half at least be different to per two codes between code, and destroyed below half still can correctly discern even this just means code.In addition, because the number of the information " 1 " of each code and information " 0 " is the same, therefore, has the function of self checking.Combination that the information " 1 " of utilizing each code and information " 0 " are arranged again is in advance as can be known, and " 1 " number of each code all is an even number except C0, so can realize the function from error correction.
We provide between a code maximum similar degree again less than 3/4, and the most significant digit of code and lowest order are the code form of " 1 ".
In above-mentioned hexacode, it is different having the content of two positions at least between any two codes, and the maximum similar degree between code is 0.67, and is more much smaller than the similar degree 0.83 of traditional binary code.In addition, the most significant digit of code and lowest order are " 1 ", can be used as the horizontal direction or the vertical direction of code are carried out self-align dot matrix.This code has the advantages that to adapt to any direction.
Fig. 2 be the present embodiment adopt with the dot matrix of code self example as six bit-identify half-tone screen codes of location dot matrix.As shown in Figure 2: first row of code and the location dot matrix of the 6th behavior at column direction, when the paper part deforms, can correctly read the dot matrix of column direction by the location dot matrix.For confirming the direction of code, first row of code is slightly different with the dot matrix of the 6th row, and the first left point of the first row dot matrix is " 0 ", and the fourth left point of the 6th row dot matrix also is " 0 ".The odd check position is classified on the code left side first as, is odd number with the number that guarantees each line code " 1 ".Secondary series to the six is classified code C0 as to C4, and the number of the code of each row " 1 " is an even number, and like this, row all can carry out odd number and even check with row, and code has fixing rule again in addition, can directly carry out the error correction of code.Secondary series, the 3rd row, the code form of the 5th row and the 6th row is as follows:
The characteristics of above code are that first code of each row and the 6th code all are numeral " 1 ".The 4th row code form is as follows:
The characteristics of above code are, first code of each row all is a numeral " 1 ", and the 6th code all be digital " 0 ", and purpose is exactly the direction of definite code.
The 4th row code form also can be placed on first row, or in other row.
Though the maximum similar degree between this code is 0.67, remove first row and the 6th location dot matrix of going, the maximum similar degree between the code of code section is 0.5.In addition, this coded representation quantity of information is 1.75 bytes, and the scope of sign is 32,768 kinds of codes.
Fig. 3 is with the dot matrix of code self example as four bit-identify half-tone screen codes of location dot matrix.Different with Fig. 3, the location dot matrix is the oblique line dot matrix of the upper left corner to the lower right corner.Every behavior even number dot matrix can carry out verification and error correction.
The dot matrix of code self is as follows as the specific code form of four bit-identify half-tone screen codes of location dot matrix:
The characteristics of above-mentioned code are, first of first line code, second of second line code, the 3rd of the third line code, last position of fourth line code all is " 1 ", and can constitute from the upper left corner to the lower right corner all is the oblique line dot matrix of " 1 ", in order to position.
Fig. 4 be another form with the dot matrix of code self example as the 6*4 bit-identify half-tone screen code of location dot matrix.As shown in Figure 4, this fotmat code has increased the anchor point of last column, and its characteristics are except can carrying out in the horizontal direction the location of diagonal line form, and vertical direction also can position.
The characteristics of the code of first row are that first is " 1 " all with last position, is used to carry out the location of horizontal direction.
The characteristics of the code of second row are that the 3rd is " 1 ", is used to carry out the location of horizontal direction.
The characteristics of the code of the third line are that the 4th is " 1 ", is used to carry out the location of horizontal direction.
The characteristics of the code of fourth line are that second all is " 1 " with the 5th, also is the location that is used to carry out horizontal direction.
Last provisional capital is " 1 ", is used for the location of vertical direction, and the expression of code direction.
With the dot matrix of code self be as the characteristics of the 6*5 bit-identify half-tone screen code of location dot matrix, each row must have two with upper for " 1 " can be used as reference point.The number of each row " 1 " is an even number, can carry out even check or error correction.The expression quantity of information is 1.5 bytes, 16,384 kinds of code forms.Maximum similar degree is that antijamming capability is stronger than natural binary code below 0.67 between code.
The size of above-mentioned sign half-tone screen code code " 1 " and spacing only are 1 to 4 printing points, therefore cover on the printed images, and naked eyes are difficult for identification, and be little to the picture quality influence.
Fig. 5 is the code constructive method of another sign property half-tone screen code.
At first provide maximum similar degree between a code less than 4 codes of 1/2, be characterized between per two codes positions different more than two being arranged.Specific code is constructed as follows:
As shown in Figure 5; It is being that cardinal rule constitutes below 1/2 with maximum similar degree between code that the code of sign property half-tone screen code is recorded and narrated part, maximum similar degree is under the situation below 1/2 between the code that sign property half-tone screen code constitutes, except code " 0 ", the number of the code of each code " 1 " all is an even number, after connecting an anchor point, the number that has constituted the code " 1 " of each line code all is an odd number, utilize the formed natural verification rule of code self, can carry out checking treatment each sign property half-tone screen code.Sign property half-tone screen code makes the number of the dot matrix code " 1 " of each row constitute even number at the most up verification dot matrix of having set up between code; Can carry out checking treatment to each row between code.Here, be that the code value of zero code is defined as odd number for the number of " 1 " with code value.Another characteristics of the formation of sign property half-tone screen code are; On two limits at adjacent the formed right angle of code, the for example left side and bottom, or top and the right side people are the means of setting up the location dot matrix: the error correction of sign property half-tone screen code is at the dot matrix distribution rule below 1/2 with maximum similar degree between code, the result of verification in addition, the overall treatment as a result of detection and localization.
For example among Fig. 5,501 behavior even check row, 502 and 503 is anchor point array and row, and 504 code values are the method for expressing of C0, and 505 code values are the method for expressing of C1, and 506 code values are the method for expressing of C2,507 code values are the method for expressing of C3.
Below just provided the dot matrix of code self example as the sign half-tone screen code of location dot matrix, not only these several half-tone screen codes are copied said method, can constitute and comprise 8,12,16,24,32, and the N position is at interior various sign half-tone screen codes.As long as the similar degree between code, uses the authentication code of the dot matrix of code self as the verification dot matrix less than below 3/4, all belong within the invention scope of the present embodiment.
