In the present embodiment, provide the method determining code element information region and image information region, code element can be realized quickly and accurately to be divided into code element information region and image information region, simply efficiently.
Step 404, uses the color value in the code element information region of code element to replace the pixel value of the position in correspondence code metamessage region in the second region to be fused of still image.
Particularly, obtain the color value in the code element information region of code element, and determine the position in correspondence code metamessage region in the second region to be fused, thus use the color value obtained to replace the pixel value of corresponding position in still image.Such as, when the color of code element is black, then the pixel value of position corresponding with the code element information region of this code element in still image is all set to black pixel value; On the contrary, when the color of code element is white, then the pixel value of position corresponding with the code element information region of this code element in still image is all set to white pixel value.
In the present embodiment, by above-mentioned steps 402 ~ step 404, code element is divided into code element information region and image information region, and uses the color value in the code element information region of code element to replace the pixel value of the position in correspondence code metamessage region in the second region to be fused of still image.The position in the code element information region of corresponding code element in still image is made to comprise code element information, the position in the image information region of corresponding code element then remains the image information of still image, reaches the object of the image co-registration of the position of corresponding with still image for code element code element.
In one embodiment, in code element fusion steps, the code element in first of Quick Response Code to be fused the region to be fused is also comprised with the step of the image co-registration of the position of corresponding code element in the second region to be fused of still image the step adjusting pixel value, specifically comprise: judge that whether code element is the code element of the attribute information representing Quick Response Code to be fused, if then adjust the pixel value of the position in the image information region of corresponding code element in the second region to be fused according to the color value in the image information region of code element; The pixel value of the position in the image information region of corresponding code element in the second region to be fused is not adjusted when being judged as NO.
Wherein, the step of step adjustment pixel value can before step 404, also can be after step 404.The each code element in image to be fused can be traveled through, perform the step of above-mentioned steps 404 and adjustment pixel value respectively.
With reference to figure 6, here first with Quick Response Code to be fused for QR code (Quick Response, responds Quick Response Code fast) illustrates the structure composition of Quick Response Code to be fused.Quick Response Code to be fused comprises attribute information district and data field, and the information in attribute information district and data field all represents with the form of code element.Wherein data field is used for the data of memory encoding, and attribute information district is for storing the attribute information of Quick Response Code to be fused, and this attribute information is the necessary information identifying Quick Response Code to be fused.Attribute information district comprises position sensing figure, position sensing figure marker space, positioning pattern, correction graph, format information and version information etc.When a code element in the first region to be fused of Quick Response Code to be fused is positioned at the attribute information district of Quick Response Code to be fused, can judge that this code element is as the code element of attribute information representing Quick Response Code to be fused.
In the present embodiment, add the step of adjustment pixel value, owing to representing that the code element of attribute information is to can correctly identify that Quick Response Code plays decisive role, fault-tolerant ability is poor, therefore should for representing that the code element of attribute information does differentiation process.Particularly, the pixel value of the position in the image information region of corresponding code element in the second region to be fused can be adjusted according to the color value in the image information region of code element.The position in the image information region of corresponding code element in fused images is made both to have remained the image information of still image like this, code element information can be embodied again, effectively improve the stability identifying Quick Response Code, guarantee that the 2 D code information in the dynamic two-dimension code image of fused images and the final acquisition generated can be correctly validated.
In one embodiment, in the step of adjustment pixel value, the step adjusting the pixel value of the position in the image information region of corresponding code element in the second region to be fused according to the color value in the image information region of code element specifically comprises: the color judging code element; If black, then reduce the pixel value of the position in the image information region of corresponding code element in the second region to be fused according to the first predetermined amplitude; If white, then increase the pixel value of the position in the image information region of corresponding code element in the second region to be fused according to the second predetermined amplitude.
In the present embodiment, because Quick Response Code scanning software is when scanning Quick Response Code, first can remove the colouring information in Quick Response Code, by Quick Response Code binaryzation, such as when representing pixel value with 0 ~ 255, pixel value lower than 128 can be judged to be black by Quick Response Code scanning software, and the pixel value of more than 128 is judged to be white.Therefore in the present embodiment, the pixel value of the position in the image information region of black code element corresponding in the second region to be fused is reduced, make the image of this position be more easily judged to be black by Quick Response Code scanning software; The pixel value of the position in the image information region of corresponding white symbol in the second region to be fused is increased, makes the image of this position be more easily judged to be white by Quick Response Code scanning software.Thus decrease the interference that the image information when identifying Quick Response Code in dynamic two-dimension code image causes, guarantee that the 2 D code information in the fused images that generates and the final dynamic two-dimension code image obtained can be correctly validated.
In one embodiment, the code element information region in code element is positioned at the central part of code element.In the present embodiment, code element information region is positioned at the central part of code element, and image information region is positioned at the surrounding of code element.In the fused images of such acquisition, the position in correspondence code metamessage region comprises code element information, the position of correspondence image information area then remains image information, and the image information of multiple positions in the image information region of corresponding adjacent code element is coupled together, when parts of images information is replaced by code element information, still can keep the overall profile of image, be conducive in fused images and the expression of general image information in dynamic two-dimension code image.
