Embodiment one
As shown in Fig. 2 a kind of image quality processing method provided in an embodiment of the present invention is it gives, can from figure
Go out, the method can include：
The display bezel of S210, the Quick Response Code of terminal detection scanning inframe, and obtain the display bezel chi of the Quick Response Code
It is very little；
It should be noted that the display bezel size of the Quick Response Code can by the resolution of the display bezel or
The surface area of the surface area of the display bezel or the display bezel is characterized with the ratio of the surface area of the scan box.It is right
The characteristic manner of Ying Di, the interval higher limit of following default identification sizes and lower limit and the display bezel chi of the Quick Response Code
Very little characteristic manner is consistent.
Whether S220, the display bezel size of Quick Response Code described in the terminal judges are in default identification size interval；
If it is, execution step S230；Otherwise, execution step S240；
It is to be appreciated that the interval two dimension being when the terminal is capable of identify that the Quick Response Code of the identification size
The size of code display bezel is interval, when the interval higher limit of the identification size is that the terminal is capable of identify that the Quick Response Code
The full-size of the Quick Response Code display bezel, the interval lower limit of the identification size is that the terminal is capable of identify that described two
The minimum dimension of Quick Response Code display bezel during dimension code.That is, when the display bezel size of the Quick Response Code is in
During the default identification size interval, illustrate that the terminal with the information content in Quick Response Code described in Direct Recognition, and can be known
Other speed；When the display bezel size of the Quick Response Code is not at the default identification size interval, illustrate described
Terminal can not recognize the information content in the Quick Response Code, or the information content being capable of identify that in the Quick Response Code, but
Recognition speed is slower.Therefore, the interval higher limit of the identification size and lower limit are a kind of empirical values.
The Quick Response Code of inframe is scanned described in S230, the terminal recognition, and is obtained in the information that the Quick Response Code is included
Hold；
S240, the terminal adjust the display bezel size of the Quick Response Code according to default adjustable strategies, and return is held
Row step S220.
Exemplarily, the display bezel of the Quick Response Code of the terminal detection scanning inframe, can specifically utilize rim detection
Algorithm obtains the display bezel of the Quick Response Code of scanning inframe.
Quick Response Code is according to certain rules in the black and white phase of plane (on two-dimensional directional) distribution with certain specific geometric figure
Between graphic recording data symbol information, that is to say, that the display image of Quick Response Code be it is a kind of be made up of monochrome pixels two
Value image, therefore, in the display picture of scanning inframe, it is possible to use existing edge detection operator is easily by scan box
The display bezel of the Quick Response Code included in interior display picture is detected.At technical field of image processing, common edge
Detective operators are broadly divided into two types：A kind of is the edge detection operator based on first derivative, by calculating image
Grad comes detection image edge, such as：Difference edge detection, Roberts operators, Sobel operators and Prewitt operators etc.；One
Kind be the edge detection operator based on second dervative, by seeking second dervative in zero crossing detecting edge, such as：
Laplace operators, LOG operators and Canny operators etc..
In above-mentioned several operators, difference edge detection is basic and original method, according to step edge situation principle,
Edge is detected using derivative operator, this operator requesting party tropism calculates loaded down with trivial details, therefore seldom adopts；Roberts operators are one
Simplest operator is planted, the effect of its detection vertical edge is better than oblique edge, it is in effect both horizontally and vertically preferably, fixed
Position high precision, but to noise-sensitive；Sobel operators spatially easily realize, can smooth noise, it is possible to provide accurate edge side
To information, but also will detect that pseudo-edge so that positioning edge definition is relatively low；The characteristics of Prewitt operators and Sobel operators
Feature is similar to, and it can preferably process the more image of gray scale gradual change and noise；Laplace operators, because the operator is two
Order difference, the double enhancing picture noise of meeting, therefore, it is more sensitive to picture noise, and the wide edge of double image element is easily produced, easily
Edge directional information is lost, but, the operator has isotropism, sensitivity, accurate positioning is mutated to gray scale, is capable of detecting when greatly
Most edges and seldom there is pseudo-edge；LOG operators not only with smoothed image but also can reduce noise；Canny operators
Noise removal capability value-based algorithm more minimum than Roberts operator, Sobel operators and Prewitt operators will be strong, and can in noise and
Preferable balance is obtained between rim detection, real weak edge is able to detect that, but the operator also easily smooths out some sides
Edge information.
Therefore, in actual applications, the terminal can be selected wherein with reference to the characteristics of above-mentioned several edge detection operators
A kind of edge detection operator come realize scan inframe Quick Response Code display bezel acquisition.
In addition, it is necessary to explanation, Quick Response Code in scan box it is shown that square-shaped patterns shape, therefore, except can be with
Outside the display bezel of the Quick Response Code that scanning inframe is obtained by rim detection, can be with directly by way of picture recognition, i.e.,
The display bezel of the Quick Response Code of scanning inframe is directly positioned and obtained using two-dimension code pattern feature.The figure of the Quick Response Code
Feature can include that the special identifier refers to two-dimension code pattern one or more in the parameters such as shape, color, special identifier
A kind of distinctive mark, such as QR codes, conventional two-dimentional code type, wherein three in its four corners are printed on similar
The square pattern of " returning " word, as shown in figure 3, therefore, it can position and obtain by " returning " the shape pattern in detection Quick Response Code
Take the display bezel of the Quick Response Code of scanning inframe.
Exemplarily, for step S240, the terminal adjusts the display of the Quick Response Code according to default adjustable strategies
Frame size, specifically can include process is implemented as follows：
When the display bezel size of the Quick Response Code higher limit interval more than the identification size, the terminal passes through
The numerical value of regulation parameter Zoom is reducing the display bezel size of the Quick Response Code；
When the display bezel of the Quick Response Code is smaller in size than the interval lower limit of the identification size, the terminal passes through
The numerical value of regulation parameter Zoom is increasing the display bezel size of the Quick Response Code.
It should be noted that parameter Zoom is the focal length for adjusting camera in the terminal, in camera position
In the case of constant, focal length is longer, claps narrower into the scenery scope of picture, and subject is also bigger.Parameter Zoom
Value in the terminal camera shoot focal length can be directly proportional, i.e. Zoom values are bigger, in the terminal camera shooting Jiao
Away from longer, the picture of shooting is bigger, and the display bezel size of the Quick Response Code of the terminal scanning inframe is also bigger；Or
Person, the focal length that the value of parameter Zoom shoots with camera in the terminal can also be inversely proportional to, i.e. Zoom values are bigger, the end
The focal length that camera shoots on end is shorter, and the picture of shooting is less, the display bezel of the Quick Response Code of the terminal scanning inframe
Size is also less.
A kind of image quality processing method is embodiments provided, the method can interpolate that the display of scanning inframe Quick Response Code
Whether frame size is interval in default identification size, when the display bezel size of the Quick Response Code is not at default identification
When size is interval, the display bezel size of the adjustment Quick Response Code can be passed through so that the terminal quickly recognizes and obtain quilt
The information content of the Quick Response Code of scanning, so as to improve the experience of user, facilitates user to the scanning of Quick Response Code and uses.
Embodiment two
For convenience to the understanding of such scheme, the embodiment of the present invention will be with reference to concrete application scene to above-mentioned technical proposal
Specific implementation process be described.
For example, we set such a scene：User A from supermarket shopping out after, it is found that information desk is carried out and " swept
Sweep " surrounded by other users around courteous activity, but the panel of the Quick Response Code now puted up, therefore user A can only be single
Handss are held high and have turned on the mobile phone of " sweep and sweep " function and be scanned against the Quick Response Code panel of distant place, now captured in scan box
Picture as shown in figure 4, it can be seen that the current value of parameter Zoom be 0.5x.Clearly for not using above-mentioned
The mobile phone of the technical scheme that embodiment one is provided, because the image in 2 D code in the picture captured by scanning inframe is too little, leads
Cause the mobile phone None- identified and obtain the information content that the Quick Response Code is included, now user A is because crowded and another
It is portable and manually to adjust the size of the Quick Response Code display picture in scan box just from the thing of supermarket's purchase, so as to shadow
Uses of the user A to two-dimensional code scanning is rung.
But, for the mobile phone for employing the technical scheme that above-described embodiment one is provided, will preferably solve above-mentioned shadow
Ring use problems of the user A to two-dimensional code scanning.Specifically, when " sweep and sweep " function of mobile phone is unlocked, mobile phone will be utilized
The display bezel of the Quick Response Code of built-in edge detection algorithm detection scanning inframe, further, mobile phone will be obtained relatively easily
Whether the display bezel size for taking the Quick Response Code is 16.0%, and judge the display bezel size of the Quick Response Code in default
Identification size interval (assume default identification size interval be [60%, 1]), it is clear that judged result is the aobvious of the Quick Response Code
Show the frame size lower limit interval less than the default identification size, therefore mobile phone by increasing parameter-embedded Zoom automatically
Numerical value come elongate the camera on mobile phone shooting focal length, the display picture of the Quick Response Code of magnified sweep inframe is come with this so that
The display bezel size of the Quick Response Code after adjustment is about 96%, it is clear that the display bezel size of the Quick Response Code after adjustment is in described
Default identification size is interval, and the display picture of the Quick Response Code after amplification is as shown in figure 5, it can be seen that parameter Zoom
