The following describes the control method provided by the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 shows a flowchart of a control method according to an embodiment of the present application, the method including:
step S1: and under the condition that the target graphic identification is displayed on the target interface, acquiring the target characteristic information of the target graphic identification.
Optionally, the target graphic identification comprises any one of a two-dimensional code, a bar code, and the like.
Optionally, identifying whether the current situation is a situation of displaying the target graphic identifier, the method includes: detecting whether the user input is used for calling out the target graphic identification. And if so, identifying the target graphic identifier in the called display interface. And if the target graphic identifier is recognized, judging that the target graphic identifier is displayed.
Otherwise, if the user input for calling out the target graphic identifier is not detected; or the target graphic identifier is not recognized in the called display interface; it is determined not to be the above-described case, thereby maintaining the current screen brightness.
Optionally, the target interface is a current display interface. The target interface, by reference, identifies the interface of the program in which the target graphic resides.
Optionally, after the target graphic identifier is identified, the area where the target graphic identifier is located on the target interface, so as to obtain the target feature information of the target graphic identifier.
Optionally, the target feature information includes, but is not limited to: pattern density, fault tolerance, etc., characteristic information that has an effect on the success rate of scanning the target pattern identifier.
Step S2: and acquiring first screen brightness corresponding to the target characteristic information according to the target characteristic information.
The first screen brightness is the lowest screen brightness which meets the requirement of successfully scanning the target graphic identifier.
The first screen brightness is preset screen brightness according to the target characteristic information.
Step S3: and acquiring the target screen brightness of the target interface.
The target screen brightness is the current screen brightness of the target interface.
The purpose of this step is to determine whether the current screen brightness supports successful scanning of the target graphic identifier.
Step S4: and controlling the target interface to keep the target screen brightness under the condition that the target screen brightness is greater than or equal to the first screen brightness.
In this step, based on the logic, when the target screen brightness is greater than or equal to the first screen brightness, which indicates that the current screen brightness supports successful scanning of the target graphic identifier, the current screen brightness is maintained.
In this way, in the embodiment of the present application, in the case of displaying the target graphic identifier, the target feature information of the target graphic identifier is first acquired. Then, in a preset corresponding relation, first screen brightness corresponding to the target characteristic information is obtained. Wherein the first screen brightness is the lowest screen brightness required for successfully scanning the target graphic identifier, and the target characteristic information may be a necessary characteristic associated with the scanning success rate. Further, the current target screen brightness of a target interface displaying the target image identifier is obtained to judge whether the target screen brightness supports successful scanning of the target image identifier, and when the target screen brightness is larger than or equal to the first screen brightness, the target screen brightness is considered to support successful scanning of the target image identifier, and the screen brightness does not need to be increased, and the current target screen brightness is kept. Therefore, the phenomenon that the screen is exploded and bright in the prior art can be effectively reduced, discomfort of eyes of a user is relieved, and harm to the eyes of the user is reduced.
In the flow of the control method according to another embodiment of the present application, step S1 includes:
substep A1: and obtaining the density and the fault tolerance rate of the target graphic identifier.
In this step, the target characteristic information includes density and fault tolerance.
Optionally, after the area where the target graphic identifier is located on the target interface, the density and the fault tolerance rate of the target graphic identifier are analyzed.
Step S2, including:
substep A2: and acquiring first screen brightness corresponding to the first target grade and the second target grade according to the first target grade corresponding to the density and the second target grade corresponding to the fault tolerance.
On one hand, the graphical identification in the embodiment has a fault tolerance function, and can still be scanned after the graphical identification is partially shielded. Therefore, the fault tolerance rate refers to the ability of the graphic identifier to be scanned after being blocked. The higher the fault tolerance, the more parts of the graphical identification can be occluded. The fault tolerance rate is represented by letters, and the fault tolerance capability grades are divided into: l, M, Q, H grades, and L, M, Q, H grades, increasing in order. Further, in L, M, Q, H, the maximum values of the fault tolerance rates corresponding to each level are 7%, 15%, 25%, and 30%, respectively.
On the other hand, the density of the graphic symbols in the present embodiment refers to the image content per unit area in the graphic symbols. The more image content per unit area, the greater the density of graphical indicia.
The value range is divided into at least two sub-ranges according to the value range of the density of the graphic identifier, each sub-range corresponds to one grade, and the corresponding grade is gradually increased along with the increase of the density of the graphic identifier in each sub-range.
Optionally, the density of graphical indicia is divided into a plurality of levels, e.g., high, medium, and low. The highest values of the densities corresponding to each grade are sequentially increased.
Therefore, by analyzing the density and the fault tolerance of the target graphic identifier, a first target level corresponding to the density of the target graphic identifier and a second target level corresponding to the fault tolerance can be obtained.
Further, a plurality of density levels and a plurality of fault tolerance levels can be combined in a cross mode, and the required lowest screen brightness is obtained by combining the density levels and the fault tolerance levels in each group and serves as the preset screen brightness of the corresponding group.
Therefore, in this step, a first screen brightness corresponding to both the first target level and the second target level is acquired.
In this embodiment, the density and the fault-tolerant rate of the target graphic identifier are combined, and the two factors affecting the scanning success rate obtain the corresponding first screen brightness according to the levels to which the target graphic identifier and the fault-tolerant rate belong, that is, the lowest screen brightness of the image identifier corresponding to the density level and the fault-tolerant rate level are scanned successfully, so that the discomfort phenomenon caused by the screen explosion to the user is avoided on the basis of ensuring that the target image identifier is scanned successfully.
In this embodiment, the obtained target feature information is related to the scanning success rate. For example, the scan success rate is associated with the complexity of the graphical identification, and thus, the target feature information includes a density that determines the complexity. In further embodiments, the target characteristic information may also include other factors associated with the scan success rate.
In the flow of the control method according to another embodiment of the present application, before step a2, the method further includes:
step B1: and determining the corresponding preset screen brightness based on any one of the at least two levels of the graphic identifier density and any one of the at least two levels of the graphic identifier fault tolerance.
And the corresponding preset screen brightness is increased along with the increase of the density grade. As the level of the fault tolerance increases, the corresponding preset screen brightness decreases.
| Density/fault tolerance ratio | L：7％ | M：15％ | Q：25％ | H：30％ |
| Is low in | 70 | 55 | 25 | 25 |
| In | 120 | 70 | 55 | 25 |
| Height of | 250 | 120 | 70 | 55 |
TABLE 1
Referring to table 1, any one of the plurality of fault tolerance levels is crossed with each density level to obtain a lowest screen brightness corresponding to the lowest fault tolerance level, which is used as a corresponding preset screen brightness.
Wherein, the lower the density, the higher the fault tolerance rate, the higher the success rate of scanning, the faster the scanning, the lower the required minimum screen brightness. And so on.
Optionally, a value range of 25-250 of the screen brightness value is referred to, the obtained combination of the density level and the fault tolerance level is combined, and a plurality of lowest screen brightness values corresponding to different combinations in one-to-one correspondence are selected from the value range of the screen brightness value according to the scanning success rate corresponding to all the combinations.
In this embodiment, according to the density and the fault tolerance of different graphic identifiers, the corresponding scanning difficulty level can be obtained, and thus the required minimum screen brightness can be obtained. For example, the harder it is to scan, the higher the minimum screen brightness required. Further, according to the difficulty degree of scanning, in the value range of the screen brightness value, the minimum screen brightness required by different difficulty degrees of scanning is determined. Therefore, the density grade, the fault tolerance grade and the preset screen brightness in the table 1 can be obtained, so that in practical application, the corresponding preset screen brightness is directly determined and then compared with the current target screen brightness, further, the situation that the graphic identification is successfully scanned frequently in a mode of exploding the screen is avoided, and discomfort and harm to a user are reduced.
In the flow of the control method according to another embodiment of the present application, after step S3, the method further includes:
step C1: and under the condition that the target screen brightness is smaller than the first screen brightness, controlling the target interface to change from the target screen brightness to the first screen brightness within a preset time according to a preset linear relation.
Optionally, the linear relationship in this embodiment may refer to the formula: and y is ax + b.
Wherein y is the first screen brightness, a is the screen brightness increase per second, x is the preset time, and b is the current target screen brightness.
Optionally, it is recommended that x is set within 2s, so that the brightness of the screen can be finished in a short time for the user to scan, and meanwhile, the phenomenon of screen explosion can be avoided.
In this embodiment, if the current target screen brightness is not enough to support successful scanning of the target graphic identifier, the screen brightness is increased to the first screen brightness in a linear adjustment manner, so that discomfort and injury to the user are effectively reduced by giving more light adaptation time to the eyes of the user on the basis of ensuring successful scanning of the graphic identifier.
In the flow of the control method according to another embodiment of the present application, after the step C3, the method further includes:
step D1: and under the condition that the brightness of the target screen is less than the first screen brightness, identifying a target area corresponding to the target graphic identifier in the target interface.
The target area is used for displaying a target graphic identification.
Step D2: the brightness of the control target area is changed from the target screen brightness to the first screen brightness.
Optionally, a linear adjustment mode is adopted to brighten the target area displaying the target graphic identifier.
In this embodiment, if the current target screen brightness is not enough to support successful scanning of the target graphic identifier, only the target area displaying the target graphic identifier is brightened, and other areas of the target interface still maintain the target screen brightness, so that discomfort and injury to the user are further reduced by reducing the screen brightness area on the basis of ensuring successful scanning of the graphic identifier.
In a flow of the control method according to another embodiment of the present application, in a case where the target screen brightness is smaller than the first screen brightness, the current target screen brightness is saved before the screen brightness is adjusted. And if the user exits the target interface, namely exits the display interface of the graphic identifier, restoring to the target screen brightness according to the linear relation of y ═ ax + b. Therefore, the screen brightness can not be continuously kept in a brighter state, and discomfort and harm to the user are further reduced.
In summary, the present disclosure is directed to determining a minimum screen brightness required by a user according to a difficulty level of scanning a graphic identifier when the user opens the graphic identifier such as a two-dimensional code, and maintaining the current screen brightness when the current screen brightness satisfies the minimum screen brightness, so as to reduce the occurrence of a screen explosion phenomenon and solve a problem of dazzling the user due to sudden strong light when the user opens the two-dimensional code. In addition, when the current screen brightness does not meet the lowest screen brightness, the screen linear gradual brightening is only carried out on the area where the graphic identification is located, the screen brightness area is reduced, certain brightness adapting time is given to human eyes, and the problem that a user is dazzling due to sudden strong light when the two-dimensional code is opened is solved. The typical scene of this application is if, sit public transit or cinema at night and open the two-dimensional code carelessly, and the cell-phone screen is very bright suddenly, causes discomfort such as dazzling, not good user experience, and this problem is effectively solved to this embodiment, brings better use for the user and experiences.
