Preferably, the size of described information symbol is pre-seted according to the identification region.For example, identification region is square, It is classified as x2It is individual square；For example, the identification region is 3*3 square centimeters, be classified as 9 it is square, it is each square to be The size of described information symbol, i.e., 1 square centimeter；And for example, 36 square, each square as described information symbols are classified as Size, i.e., 0.25 square centimeter.
Preferably, the size of described information symbol is pre-seted always according to the number of colours.For example, described information symbol Size is inversely proportional with the number of colours, and the number of colours is bigger, and described information symbol is smaller.Preferably, always according to described GTG quantity pre-sets the size of described information symbol.For example, the size of described information symbol is inversely proportional with the GTG quantity, The GTG quantity is bigger, and described information symbol is smaller.So, an information code element can accommodate bigger information content.
For example, GTG quantity is set for the various basic colors in the identification region of colored high-order latent image code, for example, by The number of colours determines each basic color, i.e., described basic color is related to the number of colours.And for example, the setting steps In, it is that the identification region of colored high-order latent image code sets number of colours and GTG quantity.And for example, in the setting steps, The GTG that identification region for colored high-order latent image code is set and the number of colours of colored high-order latent image code matches Quantity, for example, the GTG quantity is equal with the number of colours.And for example, in the setting steps, always according to the grey exponent number Amount sets the identification region of the colored high-order latent image code, so, can be according to being adjusted flexibly GTG quantity The size of identification region.For example, the identification region is directly proportional to the GTG quantity, in the present embodiment, colored high-order is stealthy The size of image code is not a rated value, but is flexibly set according to GTG quantity, and a width can be made very in practical application Big pictorial poster；Preferably, the positioning grid that the pictorial poster is viewed and admired without obvious, obstruction, so as to stealthy as colored high-order Image code uses.
Preferably, before the setting steps, in addition to step：Determine identification region.For example, a kind of colored high-order is stealthy The generation method of image code, it comprises the following steps：Determine identification region；Identification region for colored high-order latent image code is set Put GTG quantity；Obtain data to be encoded；The data to be encoded are encoded, multiple tools are generated according to the GTG quantity There is the information code element of some grades of GTGs, output includes the identification region of each described information symbol.And for example, the generation method includes Following steps：Determine identification region；For the identification region of colored high-order latent image code, GTG quantity is set；According to the GTG The identification region is set or adjusted in quantity；Obtain data to be encoded；The data to be encoded are encoded, according to the ash The multiple information code elements with some grades of GTGs of exponent number amount generation, output include the identification region of each described information symbol.
Preferably, the determination identification region, including positioning area and the information area of the identification region are determined, or, really The information area of the fixed identification region and positioning area therein or positioning mark；Or determine the information code of the identification region Positioning area or positioning mark in member.Preferably, the positioning area is set by row, for example, often row sets a positioning area.Again Such as, the determination identification region, the information area for determining the identification region is only included；So, it can obtain and substantially not position The colored high-order latent image code in area, for example, the lattice at three angles of existing Quick Response Code.Preferably, described information area is set Put the positioning area；And for example, described information symbol sets the positioning area.Preferably, each described information symbol sets an institute State positioning area；Or some described information symbols share a positioning area, for example, there is 300 information code elements, are divided into 3 groups, often Group information symbol shares a positioning area, shares 3 positioning areas；Or whole described information symbols share a positioning Area, for example, the positioning area is set in the upper left corner of the identification region, the lower left corner, the upper right corner or the lower right corner, described in whole Information code element shares the positioning area.So, the capacity of colored high-order latent image code can be increased.
Preferably, in the setting steps, the shape of described information symbol is also set up.For example, described information symbol is square Shape.Preferably, described information symbol is square.Preferably, the shape of described information symbol, example are set according to the GTG quantity Such as, the GTG quantity is bigger, and the edge of the shape of described information symbol is more；And for example, the GTG quantity is bigger, the letter The shape for ceasing symbol is more complicated；And for example, the shape of described information symbol has some convex portions, and the GTG quantity is bigger, described The convex portion of information code element is more；Preferably, the convex portion quantity of described information symbol is equal with the GTG quantity；Preferably, often One described information symbol sets a positioning area, using the positioning area of the convex portion as described information symbol.For example, The convex portion is essentially pixel grid, and the pixel grid on its both sides is colourless or light, and the convex portion is dark color.It is preferred that , according to the size of GTG quantity setting described information symbol.For example, the size of described information symbol and the grey exponent number Amount is inversely proportional, for example, the GTG quantity is bigger, described information symbol is smaller.
And for example, a kind of generation method of colored high-order latent image code, it comprises the following steps：It is hidden to pre-set colored high-order The identification region of shape image code, for example, determining the identification region of the colored high-order latent image code；Wherein, the cog region Domain is used for the information code element for placing colored high-order latent image code to be identified；For example, the identification region set positioning area with The information area, wherein, the positioning area is non-specific to offend the eye setting, i.e., it is same or like with the expression-form in described information area, no Viewed and admired as obstruction, such as the positioning area and described information area are partial graphical or image, it is preferred that the positioning area Positioning mark with some pixels composition, to identify；Pre-set the number of colours and GTG of colored high-order latent image code Quantity；Obtain data to be encoded；Coding step：The data to be encoded are encoded, export identification region.It is for example, described The information area includes some square symbols.And for example, described information area includes some rectangle symbols.Preferably, in addition to step：Using The identification region is as colored high-order latent image code and shares, such as by network sharing, and for example, is entered by mobile terminal Row is shared.
For example, pre-seting the identification region of colored high-order latent image code, the identification region includes positioning area and information Area；Preferably, the positioning area is arranged in described information area.For example, the positioning area includes correction graph, such as it is used for A fixed reference figure of matrix notation position is established, decoding software there can be moderate damage by it in image In the case of, resynchronize the coordinate image of image module；Described information area includes coding region, such as is not accounted for by functional graphic With the region that can be encoded to data or error correction code word.It should be noted that character count designator, ECI designators, The existing planar bar code technology such as separator, full stop, it is arranged at the identification region, will not be described here, of the invention and its each Embodiment is described in detail only for each inventive point, each embodiment and its correlation technique feature.
For example, pre-set the number of colours of colored high-order latent image code；For example, chromatic number based on the number of colours Amount, wherein, the color in the number of colours, including some basic colors；For example, the number of colours is 3, and it is corresponding, it is described Color includes 3 kinds of basic colors；And for example, the GTG quantity is 16, i.e., including 16 grades of GTGs, so, colored high-order latent image A total of 48 kinds of colors of identification region of code.And for example, the number of colours is 8, and the GTG quantity is 64, i.e., described color bag 8 kinds of basic colors are included, every kind of basic color has 64 grades of GTGs, totally 512 kinds of colors.And for example, colored high-order latent image code is pre-seted Number of colors scale, each number of colours in table to should quantity some basic colors, it is corresponding pre- for example, number of colours is 3 The 3 kinds of basic color RGB set, and for example, number of colours 7, the corresponding 7 kinds of basic colors pre-seted, such as the yellowish green ultramarine of blood orange Purple, by that analogy.
For example, the number of colours is 256, the GTG quantity is also 256, then a total of 65536 kinds of colors, i.e., every One basic color includes the color of 256 kinds of different GTGs, and each GTG is corresponding with the color of 256 kinds of basic colors of difference.For example, also Including step：Change or adjust the number of colours and/or the GTG quantity.Wherein, the basic color is some bases Color, such as three basic colors of RGB, and for example, 12 GTGs are coordinated per color, then a total of 36 kinds of colors.It is for example, basic Color cooperatively forms the GTG colour system of relevant rudimentary color from different GTGs.And for example, in addition to step：Pre-set number of colours and base The mapping table of plinth color；The mapping table is used in follow-up coding or decoding, phase is obtained according to number of colours The basic color information answered, for example, basic chromatic number amount is 3, corresponding basic color is RGB；And for example, basic chromatic number amount is 4, right The basic color answered is red, yellow, green and blue；And for example, basic chromatic number amount is 8, and corresponding basic color is the yellowish green ultramarine purple indigo of blood orange；And for example, Basic chromatic number amount is 64 or 128, and corresponding basic color is the related colour system set by each image processing software, by that analogy. When under normal circumstances, using factor of the number of colours as storage information, if number of colours is higher, in follow-up identification Cheng Zhong, the requirement to hardware device is higher, and has the advantages of information capacity is big；It can also be used as and deposit only with GTG quantity The factor of information is stored up, now color is intended only as the form of expression of colored high-order latent image code, and its essential storage information is Grey Quick Response Code, gray processing processing is carried out to image during identification, without considering color factors.
Wherein, the GTG be by it is most bright with it is most dark between brightness change, divide into several pieces.In order to carry out signal Input corresponding screen intensity management and control.Every digitized video all forms as combined by many points, and these points are also known as picture Plain (pixels), each usual pixel can show many different colors, and it is by three sub- pictures of red, green, blue (RGB) Element composition.Each sub-pixel, the light source of its behind can show different gray scales.And GTG is represented by most The dark stratum level to different brightness between most bright.This intermediate level is more, and the picture effect that can be presented is also finer and smoother. By taking 8bit panel as an example, 28 powers can be showed, equal to 256 luminance levels, then referred to as 256 GTGs.In lcd screen Each pixel, combined by the red, green, blue of different luminance levels, ultimately form different color points.That is, screen The color change that each is put on curtain, all it is by forming caused by the gray scale variation of three RGB sub-pixels of this point in fact. For example, the identification region for pre-seting colored high-order latent image code is matrix two-dimensional barcode, and for example, using PDF417, The code systems such as Datamatrix, QR Code, Code 49, Code 16K, Code one set the knowledge of colored high-order latent image code The related encoding and decoding rule on other region and basis, but not with various embodiments of the present invention for positioning area, the information area and information code element Deng extra setting mutually conflict, the difference with existing code system, be defined by the explanation of various embodiments of the present invention.Below mainly with Illustrate various embodiments of the present invention exemplified by QR Code codes, but it is understood that, various embodiments of the present invention are equally applicable to other codes The colored high-order latent image code of system.For example, using QR Code codes, the identification region of colored high-order latent image code is pre-seted. For the ease of adapting to various use environments, and for example, the color of colored high-order latent image code is pre-seted according to target identification ability Quantity, it includes GTG quantity, for example, set 8 grades of GTGs, 16 grades of GTGs, 64 grades of GTGs, 128 grades of GTGs, 256 grades of GTGs, 512 grades of GTGs, 1024 grades of GTGs or 2048 grades of GTGs or even 65536 grades of GTGs etc..
It is as follows to refer to 1 dimension code information storage：
X bars black and white 1 ties up code information storage：2x；
For example, it is 1bit (2 that 1 black and white 1, which ties up code information storage,1=2) it is 2bit that, 2 black and white 1, which tie up code information storage, (22=4) it is 3bit (2 that, 3 black and white 1, which tie up code information storage,3=8).
X bar n GTGs 1 tie up code information storage：nx；
For example, 14 GTGs 1 dimension code information storage is 1bit (41=4)；24 GTGs 1 dimension code information storage is 2bit(42=16)；34 GTGs 1 dimension code information storage is 3bit (43=64).
And for example, one 10 1 dimension code information storages are as follows：
10 black and white 1 ties up code information storage：210Bit information storages.
10 4 ranks 1 tie up code information storage：410Bit information storages.
10 n ranks 1 tie up code information storage：n10Bit information storages.Visual information storage increases considerably.
2 dimension code information storages are expanded to again：
X bars black and white 2 ties up code information storage：2(2X)；
X bar n ranks 2 tie up code information storage：n(2X)；For example, described information area includes some square symbols；For example, using Square 2 dimension code, then it is n that X bars n ranks 2, which tie up code information storage,(2X), and for example, described information area includes some rectangle symbols；For example, Code is tieed up using rectangle 2, then in same identification region, the long wide Y of X+, vertical and horizontal common X+Y bars n ranks colour 2 ties up code information storage For n(X+Y)。
One 10 2 dimension code information storages are as follows for another example：
10 black and white 2 ties up code information storage：220Information storage.
10 4 ranks 2 tie up code information storage：420Information storage.
10 8 ranks 2 tie up code information storage：820Information storage.
10 n ranks 2 tie up code information storage：n20Information storage.
And for example, using color as another information recording medium, such as there are three kinds of basic colors, i.e. three primary colours, then X bars 2 It is as follows to tie up code information storage：
The rank three primary colours 2 of X bars 4 tie up code information storage：(3*4)(2X)Information storage.
The rank three primary colours 2 of X bars 8 tie up code information storage：(3*8)(2X)Information storage.
X bar n ranks three primary colours 2 tie up code information storage：(3*n)(2X)Information storage.
And for example, using color as another information recording medium, such as there are 64 kinds of basic colors, i.e. 64 primary colours, then X bars 2 It is as follows to tie up code information storage：
The primary colours 2 of 4 rank of X bars 64 tie up code information storage：(64*4)(2X)Information storage.
