General default number is usually any value to be taken in [0,255], but optional default number is 128, each meeting It is by the color component change of a default number in three color components, and by this color component change default number Two values, the color that the two numerical value eventually form can be used to distinguish, the binary operator (0 and 1) of two dimensional code to be processed, It is namely equivalent to, obtains the mapping relations of preset color and binary operator, facilitate later period two dimension code reading.The two numerical value The numerical value that can be pre-defined optional two values can not also be done herein in [0,255] depending on being needed according to user It limits.
Illustratively, if two dimensional code to be processed by set region be not divided set region, this is set region Interior color can be original color in black or white, that is, two dimensional code to be processed；It is, color difference components U and Two color difference components of color difference components V are the second color component of default number and the third color component of default number, brightness Component Y is the first color component of default number change.The luminance component Y of default number change is where luminance component Y The brightness range in remove numerical value other than 128.The color is by the color difference components U of default number, the color difference point of default number Amount V and luminance component Y is obtained.The color difference components U of default number can be that the color difference components V of 128, default number can be 128 and luminance component Y can be negated 128 numerical value, for example, luminance component Y is 0 or 255.The case where luminance component Y is 0 Under, then original color in two dimensional code to be processed is black；Or in the case where luminance component Y is 255, then two dimension to be processed Original color in code is white.
If two dimensional code to be processed set region be have been divided, and reset color set region, then this is set Color in region, the resetting color set in region in two dimensional code exactly to be processed.It is, it is, color difference components U The second color component and color difference components V for default number change are the third color component of default number, and luminance component Y is First color component of default number change.It is, color difference components U, default number that the color is changed by default number What the color difference components V and luminance component Y of default number change was obtained.Color difference components U is the second color of default number change Component, color difference components U is the numerical value removed other than 128 within the scope of the color difference where the color difference components, for example, color difference components U is 0 or 255.Default number change color difference components U can for 0 or 255, default number color difference components V can be 128 with And luminance component Y can be 0 or 255.In this way can be on the Color mode that last time is set region, only one color of change divides Amount is equivalent to the color difference components U plane for being embedded in default number change on the two dimensional code of luminance component Y using color difference components U A two dimensional code.
Similarly, color difference components U be default number the second color component and color difference components V be default number change third Color component；Alternatively, the second color component for changing of two color difference components default numbers of color difference components U and color difference components V and The third color component of default number change；Then again by the first color component and the second color component and third color component When, luminance component Y is 0 or 255.Color difference range where above-mentioned color difference U component is [0,255], where above-mentioned color difference V component Color difference range is [0,255], and the Color Range where above-mentioned color is [0,255].It is equivalent to, above-mentioned color includes: original Color and resetting color, specific color determine according to the actual situation.
In order to get two dimensional code to be processed, this step 110 can be using following at least one possible realization side Formula obtains two dimensional code to be processed, specifically includes:
In one possible implementation, from preset two-dimensional code data library, obtain any two dimensional code, by this two Tie up code conduct, two dimensional code to be processed；Preset two-dimensional code data library is for storing the pre-stored required two dimensional code of user.In this way User is facilitated to be directly obtained two dimensional code to be processed.
Since above-mentioned preset two-dimensional code data inventory is the committed memory the problem of, to solve this problem, another In the possible implementation of kind, the binary sequence of the two dimensional code of reception user's input, the preset rules based on binary sequence, Generate two dimensional code to be processed.User can input binary sequence in real time in this way, reduce above-mentioned preset two-dimensional code data library Committed memory, generates two dimensional code to be processed in time, also meets the requirement that user inputs two dimensional code in time.
Above-mentioned binary sequence is made of binary operator, and wherein binary operator is respectively 0,1.First binary system is calculated Symbol is one in binary operator, and the second binary operator is another in binary operator.For example, the first binary system is calculated Symbol is 0, and the second binary operator is 1；Second binary operator is 1, and the first binary operator is 0.
The preset rules that following binary sequence is used in above-mentioned alternatively possible implementation, generate to be processed two Tie up code:
By every tetrad of the binary sequence of two dimensional code, it is divided into one group of binary system subsequence；By all groups Binary system subsequence, generate two dimensional code to be processed.Subsequent use is facilitated to handle every group of binary system subsequence in this way, side Just region is set where every four binary numbers of later-stage utilization to be decoded.
Step 120, each region that set is divided as L row × L column resetting color area, and L is greater than or equal to 2.
Wherein, if the unallocated color for being set region can pass through scanning as black or white in two dimensional code to be processed The color for being set region of two dimensional code to be processed or the resetting color for resetting color area, and then distinguish and obtain binary sequence.
If being set the color in region as black or white, these are already divided into L by region is set2It is a set region after, Division is obtained into L2It is a to be set region, referred to as reset color area.
In this step 120, divides each region that set and specifically included as L row × L resetting color area arranged: is irregular to draw Divide each region that set as L row × L column resetting color area.As long as the resetting color zones of respective resetting color can be shown Domain belongs to protection scope of the embodiment of the present invention.
Due to irregularly dividing each resetting color area size for being set region and may be such that two dimensional code shows It is different, it has not been convenient to which that the size of unified adjustment resetting color area it is uncomfortable also to make user's visual sense, therefore in order to solve this A problem, step 120 of the embodiment of the present invention can be using following at least one possible implementations, and division is each to be set region The resetting color area arranged for L row × L:
In one possible implementation, point each region that set is evenly dividing as L row × L column resetting color zones Domain.In this way can be according to the number of the required division of unified setting, division is each to be set region, further, it is possible to convenient uniform It shows resetting color area, improves users'comfort.
