and 11, acquiring a plurality of identification codes to be displayed.
In this step, when a plurality of identification codes to be displayed are obtained, specifically, the content to be identified may be obtained, the content to be identified is divided into a plurality of parts of content, and identification codes corresponding to each part of content are respectively generated to obtain a plurality of identification codes.
The identification code may be a bar code or a two-dimensional code, and the like.
The content to be identified may be, but is not limited to, text, links, pictures, and other information. The specific way of dividing the content is various, for example, for text, the content may be divided into multiple sentences or multiple segments according to semantics, for link, the content may be divided in units of one link, for picture, the content may be divided in units of one picture, and so on. When the identification code is generated, reference may be made to an existing generation technology, for example, when the identification code to be displayed is a two-dimensional code, the existing two-dimensional code generation technology is adopted to generate the corresponding identification code, which is not described herein again.
And 12, displaying each identification code in a time-sharing manner in a preset display area.
In the scheme of this application, can show when a plurality of discernment code division based on same display area, compare with the correlation technique, in the display area of equidimension, can show more recognizable content, resource utilization is higher, can reach environmental protection effect.
In practical application, if the content to be identified by the identification code is more and the limited display area is not enough to contain all the content, the content to be identified can be divided into a plurality of parts of content, the identification code is generated for each part of content respectively, the identification code corresponding to each part of content is obtained, and then each identification code is displayed in a time-sharing manner based on the same display area, so that the display of the identification code to be displayed is realized.
Specifically, there are various implementations of the step 12, and the following list is illustrative but not limiting of several possible implementations.
In a possible embodiment, in the step 12, displaying each identification code in a preset display area in time may specifically include: and displaying different identification codes in the preset display area at different time periods. In this embodiment, a plurality of time periods are set, one identification code is displayed every time one time period is reached according to the display sequence of each part of content, and after the time period is ended, the display of the identification code is ended, the next time period is entered, and the next identification code is displayed. The duration of each time period can be equal, the duration can be set according to actual needs, the duration can be set to be shorter, and rapid time-sharing display is achieved, for example, the duration of the time period is set to be within 10 seconds, for example, 5 seconds.
Suppose that the content to be identified is divided into 3 parts of content, 3 corresponding identification codes are generated, each 5 seconds is a time period, the first identification code is displayed in the display area for 5 seconds, then the second identification code is displayed in the display area for 5 seconds, and finally the third identification code is displayed in the display area for 5 seconds, according to the display sequence, so that the display of the identification codes to be displayed is realized.
In another possible embodiment, in step 12, displaying each identification code in a preset display area, includes: grouping the identification codes; and displaying different groups of identification codes in the preset display area at different time periods. When grouping, the number of the identification codes of at least one group is more than or equal to 2. In this embodiment, the difference from the previous implementation manner of step 12 is that two identification codes can be displayed in a time period, and a specific implementation manner is exemplified below by taking a two-dimensional code as an example.
It is understood that the two-dimensional code includes a position detection pattern (see the pattern surrounded by the circle 20 in fig. 2), which may refer to the related art and is not described herein again. Then, the displaying the identification codes of different groups in the preset display area at different time periods may specifically include: when displaying each group of identification codes, selecting one identification code from the group of identification codes as a main identification code, and respectively using other identification codes in the group of identification codes as slave identification codes; as shown in fig. 3, the master id 31 is displayed in a predetermined display area, and the slave id 32 is displayed in an area where the position detection pattern of the master id 31 is located. In the present embodiment, in order to increase the content that the identification code can contain, the area where the position detection pattern is located is fully utilized, and the area is also used as a display area, and a small amount of recognizable content is added, so that the recognizable content of the identification code is increased as a whole, and the content capacity of the identification code is increased.
Since the display area of the master id is larger than that of the slave id, it is necessary to ensure that the master id contains more content than the slave id. Correspondingly, when the content to be included is divided, the difference between the number of the different parts of the content can be made larger, specifically, the content to be identified can be divided according to the size of the preset display area and the size of the area where the position detection graph is located, for example, the content to be identified can be divided into 8 parts of content, a larger part of the content of part 1, a smaller part of the content of parts 2, 3 and 4, a larger part of the content of part 5 and a smaller part of the content of parts 6, 7 and 8, then, when displaying, the identification codes corresponding to the parts 1 to 4 can be divided into a first group, the identification code corresponding to the part 1 of the content can be used as a main identification code, the identification code corresponding to the parts 2 to 4 of the content can be used as a slave identification code, similarly, the identification codes corresponding to the parts 5 to 8 of the content can be divided into a second group, and the identification code corresponding to the part 5 of the content can be used as a main identification code, the identification codes corresponding to the 6 th to 8 th parts of contents are used as slave identification codes, 5 seconds are still used as a time period, the 1 st 5 seconds are used for displaying the main identification codes of the first group in the display area, 3 slave identification codes are displayed in the areas where the detection graphs at the three positions of the main identification codes are located, the 2 nd 5 seconds are used for displaying the main identification codes of the second group in the display area, and 3 slave identification codes are displayed in the areas where the detection graphs at the three positions of the main identification codes are located.
In another possible embodiment, the grouping the identification codes includes: grouping the three identification codes into a group; correspondingly, in different time periods, different groups of identification codes are displayed in the preset display area, which may specifically include: when each group of identification codes is displayed, the identification codes are respectively displayed in three areas (such as A, B, C areas shown in fig. 4) of the preset display area divided by the Y shape, and two adjacent identification codes share two position detection graphs. This embodiment provides another kind of new display form of identification code, can see from fig. 4, the display form of this embodiment, three-dimensional display effect has been reflected, to the occasion that needs to show a plurality of two-dimensional codes, originally, 9 position detection figures are needed, if regard as above-mentioned identification code with a plurality of two-dimensional codes, three two-dimensional code sharing position detection figure, only need four position detection figures (the position of position detection figure has been schematized to dot 40 in fig. 4) can, this kind of multi-dimensional display form, the region that the position detection figure occupy has been saved greatly, the capacity of distinguishable content has been increased, the outward appearance aesthetic measure has also been promoted, more can let the two-dimensional code exert more diversified, more humanized service's effect, just can let the user higher to the viscosity nature of product.
In practical application, based on the solutions of the above embodiments, dynamic display of the identification code can be completed in a short time, and in this process, the displayed identification code can be identified by using a corresponding identification code identification technology, so that the content to be identified can be obtained. For example, based on the delayed photography function of the camera, all displayed identification codes are recorded by using the default delay algorithm of the camera and corresponding contents are identified, so that high-capacity display is achieved while all contents can be rapidly and normally displayed, and user experience is guaranteed while the function is achieved. The delay algorithm of the camera is a mature technology, and can be implemented by reference, which is not described herein again.
