Detailed Description

In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
Example one
In the embodiment of the application, the execution subject of the flow is the mobile terminal. The mobile terminal includes but is not limited to: the device comprises a tablet computer, a smart phone and the like which can execute two-dimensional code display operation. Fig. 1 shows a flowchart of an implementation of a two-dimensional code display method provided in an embodiment of the present application, which is detailed as follows:
in step 101, detecting whether a two-dimensional code to be scanned exists in a display page of a current mobile terminal;
in the embodiment of the application, when the mobile terminal is in a bright screen state, whether the two-dimensional code to be scanned exists in a display page of the current mobile terminal can be detected, wherein the two-dimensional code to be scanned specifically refers to a payment code. Optionally, the mobile terminal may continuously detect whether the two-dimensional code to be scanned exists in the display page in a bright screen state; or, the mobile terminal may periodically detect whether the two-dimensional code to be scanned exists in the display page in a bright screen state; or the mobile terminal may also monitor whether a payment application program runs in the current foreground in a bright screen state, and continuously or periodically detect whether a two-dimensional code to be scanned exists in the display page when the payment application program runs in the foreground, where the execution time of step 101 is not limited here. Optionally, as shown in fig. 2, the step 101 specifically includes:
in step 1011, when the display page of the mobile terminal is refreshed, detecting whether a two-dimensional code exists in the refreshed display page;
in the embodiment of the application, the mobile terminal may be configured with a two-dimensional code detection module, and whenever a display page of the mobile terminal is refreshed (for example, when page jump is performed, a page needs to be refreshed), it may be detected whether a two-dimensional code exists on the refreshed display page. And if the two-dimension code does not exist in the refreshed display page, suspending the detection of the current display page, namely, in the process of displaying the current refreshed display page by the mobile terminal, not continuously detecting whether the two-dimension code to be scanned exists in the display page.
In step 1012, if two-dimensional codes exist in the refreshed display page, counting the number of the two-dimensional codes;
in the embodiment of the application, when it is detected that the two-dimensional code exists in the display page, it is considered that the two-dimensional code for payment often exists independently, that is, the mobile terminal often does not display a plurality of different two-dimensional codes during payment, so that the number of the two-dimensional codes displayed on the display page after refreshing can be further counted at this time, and the possibility that the two-dimensional code displayed at present is the two-dimensional code to be scanned is estimated based on the number of the two-dimensional codes.
In step 1013, if the number of the two-dimensional codes is one, it is determined that the two-dimensional code to be scanned exists in the display page of the current mobile terminal.
In the embodiment of the application, when the number of the two-dimensional codes is one, it can be considered that the probability that the two-dimensional code to be scanned exists in the display page of the current mobile terminal is high. Further, in order to improve the detection accuracy of the two-dimensional codes to be scanned, when the number of the two-dimensional codes is one, it can be determined whether the mobile terminal is currently in a code scanning payment scene by adopting other methods:
for example, a target application and a target interface for displaying the two-dimensional code may be obtained, that is, the two-dimensional code called by the interface of the application is obtained. Specifically, in a payment scenario, the two-dimensional code to be scanned is necessarily a two-dimensional code generated by calling a payment interface by an application program with a payment function, but not other types of two-dimensional codes, for example, when a friend is added to the two-dimensional code, a mobile terminal may also generate the two-dimensional code and display the two-dimensional code on a page for others to scan the code; or when reading public account content and microblog content, the tail ends of the content can often display two-dimensional codes for others to scan codes so as to realize the attention function: obviously, the two-dimensional codes are not in the scope of the two-dimensional codes to be scanned for code scanning payment in the embodiment of the present application. Therefore, the target application program and the target interface for displaying the two-dimensional code can be detected, and the two-dimensional code is more likely to be the two-dimensional code for code scanning payment only when the target application program is the payment application program and the target interface is the payment interface.
Secondly, whether the mobile terminal is in a payment scene can be further judged according to the current position of the mobile terminal. Generally, in the residential category, there are few scenarios where payment is made by a code scanning device. In fact, the code scanning device is often used in some formal commercial places, and ordinary small vendors, small stores and the like often adopt a user code scanning merchant to complete payment instead of the merchant code scanning user to complete payment. Therefore, the current position of the mobile terminal can be detected simultaneously, and the two-dimensional code is more likely to be a two-dimensional code for code scanning payment only when the mobile terminal is currently located in a preset area, namely a preset commercial place.
Or, whether the mobile terminal is in the payment scene or not can be judged according to the current posture of the mobile terminal. Generally speaking, a code scanning device adopted by a merchant often requires a mobile terminal of a user to be placed flat with a screen facing downward (i.e., the screen is parallel to a horizontal plane) for code scanning payment; or the mobile terminal of the user is required to be vertically placed, the screen is forward (namely the screen is vertical to the horizontal plane), and code scanning payment is carried out. When a user plays a mobile phone to read the contents of the microblog or the public number (in this case, a two-dimensional code may be carried in the contents), or when a friend is added to the contents by scanning the code for another person, the screen of the mobile terminal often forms a certain inclination angle with the horizontal plane. Therefore, by detecting the posture of the mobile terminal, the two-dimensional code is more likely to be the two-dimensional code for code scanning payment only when the mobile terminal is currently in the posture that the screen is horizontally or vertically placed. Of course, considering that it is difficult for a user to achieve an absolute horizontal placement and an absolute vertical placement when holding the mobile terminal, the horizontal placement actually refers to a preset horizontal range (i.e., allowing the horizontal direction to be inclined within a preset angle range), and the vertical placement actually refers to a preset vertical range (i.e., allowing the vertical direction to be inclined within a preset angle range), which is not limited herein.
Further, a front camera of the mobile terminal can be triggered to judge whether the mobile terminal is in a payment scene. If the front camera detects that a code reading window of code scanning equipment exists in front, the two-dimensional code can be considered to be a two-dimensional code for code scanning payment.
The above-mentioned several ways of detecting whether the mobile terminal is in the code scanning payment scenario may be executed simultaneously or may be executed by choosing, which is not limited herein.
In step 102, if the two-dimension code to be scanned exists, storing the two-dimension code to be scanned as a two-dimension code image to be scanned;
in this embodiment of the application, once it is detected that the two-dimensional code to be scanned exists in the display page, the mobile terminal may store the two-dimensional code to be scanned as a two-dimensional code image to be scanned, so as to be used in subsequent adjustment and display. Optionally, for the payment security of the user, the two-dimensional code image to be scanned is not stored in a media library directly accessible from the foreground, but stored in a cache database. Optionally, as shown in fig. 3, the step 102 specifically includes:
in step 1021, detecting whether the two-dimensional code to be scanned has a storage option, if yes, executing step 1022, and if not, executing step 1023;
in the embodiment of the application, some two-dimensional codes can pop up a storage option through long-time pressing operation of a user; considering that the two-dimensional code to be scanned is a payment code, the possibility that the storage function is disabled exists, and therefore, whether the two-dimensional code to be scanned has a storage option or not can be detected first, specifically, whether the mobile terminal simulates long-time pressing operation of a user or not, and whether the two-dimensional code to be scanned has the storage option or not is detected by whether a storage option frame is popped up or not.
In step 1022, a two-dimensional code storage instruction is generated, and the two-dimensional code to be scanned is stored as a two-dimensional code image to be scanned based on the two-dimensional code storage instruction;
in this embodiment of the application, if it is detected that the two-dimensional code to be scanned has a storage option, it can be known that the two-dimensional code to be scanned can be currently stored, based on this, a two-dimensional code storage instruction can be generated, and based on the two-dimensional code storage instruction, the two-dimensional code to be scanned is stored as a two-dimensional code image to be scanned.
In step 1023, a screen shot is performed on the current page to obtain a screen shot image;
in the embodiment of the application, if it is detected that the two-dimensional code to be scanned does not have a storage option, it can be known that the two-dimensional code to be scanned cannot be stored currently, and based on this, a screenshot function of the system can be called to perform screenshot on the current page, so as to obtain a screenshot image. Alternatively, the screenshot image may be temporarily stored in the cache database instead of the media library.
In step 104, the two-dimensional code to be scanned is segmented in the screenshot image, and the segmented two-dimensional code to be scanned is stored as a two-dimensional code image to be scanned.
In this embodiment of the application, the two-dimensional code to be scanned is first positioned in the screenshot image to determine a specific position of the two-dimensional code to be scanned, then the two-dimensional code to be scanned is segmented based on the specific position of the two-dimensional code to be scanned in the screenshot image, and the segmented two-dimensional code to be scanned is stored as a two-dimensional code image to be scanned. Optionally, after the payment operation based on the two-dimensional code to be scanned is completed, deleting the two-dimensional code image to be scanned from the cache database to avoid that the two-dimensional code image continues to occupy system resources of the mobile terminal.
In step 103, adjusting the size of the two-dimensional code image to be scanned based on the screen size of the mobile terminal;
in the embodiment of the application, when the application calls the two-dimensional code to be scanned to be displayed in the page, the two-dimensional code is often large in size and occupies the central position of the screen, so that the code scanning device is not easy to align when code scanning operation is performed. Therefore, in the embodiment of the present application, when the two-dimensional code image to be scanned, which is saved and obtained based on the two-dimensional code to be scanned, is obtained, the size of the two-dimensional code image to be scanned may be adjusted based on the screen size of the mobile terminal. Optionally, as shown in fig. 4, the step 103 specifically includes:
in step 1031, acquiring the screen size of the mobile terminal;
in step 1032, a target width value is calculated based on the screen size and a preset adjustment ratio;
in the embodiment of the present application, the mobile terminal may first obtain its screen size from its own parameters. Considering that the mobile terminal is generally rectangular, here, when obtaining the screen size, the length value of the short side of the mobile terminal is focused, and the target width value is obtained based on the multiplication of the length value of the short side and the preset adjustment ratio. Alternatively, the adjustment ratio may be a fixed value, such as 0.3, 0.4, etc.; or, the adjustment ratio may also be a dynamically changing value, specifically, the distance between the mobile terminal and the code scanning device may be obtained through a distance sensor disposed on the front side of the mobile terminal, and it is considered that the smaller the distance is, the closer the screen of the mobile terminal and the code scanning device is, the larger the area on the screen display area read by the code scanning device is, and the smaller the area occupied by the object with the same size on the screen display area is; thus, the target width value may be adjusted in a proportional relationship based on the distance within a preset ratio range, which may be [0.2,0.8] for example, and is not limited herein. Further, when the adjustment ratio is a fixed value, the target width value may also be uniquely determined, and based on this, the target width value may be locally stored in the mobile terminal after the target width value is obtained through initial calculation; when the method of the embodiment of the application is needed to be used for displaying the two-dimensional code subsequently, the target width value can be directly called to adjust the size of the two-dimensional code image to be scanned.
In step 1033, the size of the two-dimensional code image to be scanned is adjusted according to the target width value.
In this embodiment of the application, after the target width value is obtained, the two-dimensional code image to be scanned is scaled, so that the width of the two-dimensional code image to be scanned matches the target width value.
In step 104, the two-dimensional code image to be scanned after the size adjustment is displayed at more than two preset positions of the screen of the mobile terminal.
In this embodiment of the application, after the size adjustment operation is performed on the to-be-scanned two-dimensional code image, the to-be-scanned two-dimensional code image after the size adjustment may be displayed at a plurality of preset positions on the screen of the mobile terminal. Specifically, the adjustment ratio may correspond to a plurality of different preset positions. For example, when the adjustment ratio is 0.4, the display condition of the two-dimensional code image to be scanned is as shown in fig. 5-a; when the adjustment ratio is 0.25, the display condition of the two-dimensional code image to be scanned is as shown in fig. 5-b, and the corresponding relationship between the adjustment ratio and the preset position is not limited here. Through step 104, a tiling operation of the two-dimensional code to be scanned on the screen can be realized. Optionally, an execution time may be defined for the step 104, for example, the two-dimensional code image to be scanned after the size adjustment is displayed at two or more preset positions on the screen of the mobile terminal, and is kept for a preset time period; after a preset time period, returning to the original display page, that is, returning to the display page in step 101; or after the code scanning device reads the two-dimensional code and successfully executes the deduction operation, triggering a display page to display the related feedback information of successful payment.
Therefore, in the embodiment of the application, the mobile terminal determines whether the mobile terminal is in a payment scene currently through modes such as posture and position, the size of the two-dimensional code to be scanned is adjusted in the payment scene, the two-dimensional code after size adjustment is finally tiled and displayed on a screen, and the success rate of the code scanning device in reading the two-dimensional code of the mobile terminal can be improved to a certain extent.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
