Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first luminance difference value may be referred to as a second luminance difference value, and similarly, the second luminance difference value may be referred to as a first luminance difference value without departing from the scope of the present application. The first luminance difference value and the second luminance difference value are both luminance difference values, but are not the same luminance difference value.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal according to an embodiment. In one embodiment, a light sensor is embedded in the terminal, and the light sensor is used for detecting the light intensity around the terminal so as to automatically adjust the display brightness of the screen of the terminal. It should be noted that the terminal of the present embodiment includes, but is not limited to, any terminal device such as a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), a vehicle-mounted computer, and a wearable device.
For example, the display brightness of the terminal and the light intensity detected by the light sensor can be shown in the following table:
| intensity of light sensing | Automatically configured display brightness |
| [0,200) | 25 |
| [200,400) | 55 |
| [400,1000) | 70 |
| [1000,3000) | 90 |
| [3000, infinity) | 250 |
Accordingly, the terminal can automatically configure a display brightness according to the current light intensity through the corresponding relationship between the light intensity and the display brightness shown in the table above, so that the display brightness of the terminal is adjusted to the display brightness corresponding to the current light intensity.
It is to be understood that the corresponding relationship between the light intensity and the display brightness is not limited to the above relationship, and different corresponding relationships between the light intensity and the display brightness may be configured as required, and is not limited herein. In addition, the method for automatically adjusting the display brightness of the terminal is not limited to adjustment through the corresponding relationship between the light intensity and the display brightness, as long as the method can automatically adjust the display brightness of the terminal according to the current light intensity.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting display brightness according to an embodiment. In an embodiment, as shown in fig. 2, a method for adjusting display brightness is provided, and this embodiment is illustrated by applying the method to a terminal, it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes steps 210 to 220.
The target application refers to an application program selected to enter by a user on the terminal. The first display brightness is display brightness which is automatically configured by the terminal according to the current light intensity sensed by the light sensor when the terminal enters a target application. The second display brightness is the display brightness which is automatically configured by the terminal according to the light intensity of the target application when the target application exits. And presetting display brightness as the total brightness of the terminal manually adjusted by a user when the target application exits. It should be noted that the preset brightness difference may be a negative value or a positive value, and is determined according to the actual adjustment condition of the user. Specifically, if the user feels that the display brightness automatically adjusted by the terminal is too dark, the display brightness needs to be adjusted to a brighter degree, and at this time, the preset brightness difference value is a positive value; if the user feels that the display brightness automatically adjusted by the terminal is too bright, the display brightness needs to be adjusted to a darker degree, and at the moment, the preset brightness difference value is a negative value.
In this embodiment, the target application exits, which may be the case that the user makes the target application enter the background, or the case that the user directly closes the application.
And step 220, adjusting the display brightness of the terminal to the target display brightness according to the preset brightness difference value and the first display brightness.
The target display brightness refers to the display brightness determined according to the preset brightness difference value and the first display brightness, and the terminal adjusts the display brightness to the target display brightness. In this step, since the target display brightness is obtained according to the preset brightness difference and the first display brightness, the target display brightness is closer to the viewing habit of the user when the target display brightness is compared with the display brightness automatically configured at the terminal. Optionally, if the preset brightness difference value is a positive value, the target display brightness is greater than the first display brightness; if the preset brightness difference value is a negative value, the target display brightness is smaller than the first display brightness; and if the preset brightness difference value is zero, the target display brightness is the first display brightness.
In this embodiment, when the user reenters the target application, the first display brightness of the terminal and the preset brightness difference corresponding to the target application may be obtained, so that the display brightness of the terminal is adjusted to the target display brightness according to the preset brightness difference and the first display brightness, that is, when the user reenters the application, the obtained target display brightness is more accurate with reference to the brightness of the terminal manually adjusted by the user when the application exits on the basis of the automatic brightness adjustment of the terminal, and the adjustment accuracy of the display brightness is improved when the user reenters the application. In addition, the brightness does not need to be manually adjusted again by the user under the application, and the adjustment efficiency of the display brightness is improved.
It will be appreciated that the method of the above embodiment is applicable to situations where the target application is not first opened.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating that a user manually adjusts the display brightness of the terminal to a preset display brightness according to an embodiment. As shown in fig. 3, during the use of the application program by the user, L1 is the display brightness automatically adjusted by the terminal, and since the user feels that the visibility and the comfort are not enough, the display brightness is adjusted to the preset display brightness L2, and the preset brightness difference Δ L is L2-L1. And when the user exits the application program, the target application and the preset brightness difference value are stored in an associated manner. When the user re-enters the target application, the first display brightness L3 automatically configured by the terminal is obtained, so that the display brightness of the terminal is adjusted to the target display brightness according to the first display brightness L3 and the preset brightness difference Δ L.
Referring to fig. 4, fig. 4 is a flowchart illustrating a refinement for obtaining a preset luminance difference according to an embodiment. In one embodiment, as shown in fig. 4, the step of obtaining the preset brightness difference value corresponding to the target application includes steps 410 to 430.
The configuration table is obtained according to a history record of manual brightness adjustment of a user and is used for obtaining a preset brightness difference value. Specifically, the configuration table includes at least one correspondence between the application identifier and the luminance difference value. The application identification refers to an identification representing the identity of the target application. Generally, the application identifiers should have uniqueness, and the corresponding application identifiers of different applications should be different from each other. Alternatively, the application identifier may be an application name, for example, the application identifier is an application name such as "WeChat", "Tencent video", or the like. In addition, each application may be assigned a number, such as WeChat labeled "001", Tencent labeled "002", and so on. It should be noted that, the application identifier may be configured for the application according to needs, and this embodiment is not limited. For example, in this embodiment, an application identifier is taken as an example of an application name, and a schematic diagram of a configuration table is provided, as shown in the following table:
| application identification | Difference in brightness |
| △L1 | |
| Tencent video | △L2 |
And the target application identification is consistent with the application identification corresponding to the target application. For example, if the opened application is WeChat, the "WeChat" in the configuration table is the target application identifier of the embodiment.
And step 430, taking the brightness difference value corresponding to the target application identifier as the preset brightness difference value.
In this step, for example, if the target application identifier is "WeChat", the preset luminance difference is Δ L1。
In this embodiment, in the process of obtaining the preset brightness difference corresponding to the target application, the preset brightness difference is obtained through a pre-stored configuration table, and obtaining the preset brightness difference can be achieved without too much calculation power. In addition, the configuration table is obtained according to the historical record of the manual brightness adjustment of the user, so that the use habit of the user is accurately recorded, and the obtained preset brightness difference value is more accurate.
Referring to fig. 5, fig. 5 is a flowchart illustrating another method for adjusting display brightness according to an embodiment. In the present embodiment, it is adapted to perform a pre-determination process before reading the configuration table. In one embodiment, the method for adjusting the display brightness includes steps 510 to 530.
The brightness adjustment white list is provided with an application capable of performing brightness adjustment, and the application set in the brightness adjustment white list can perform adjustment of display brightness by the methods of the above embodiments.
Specifically, in the process of actually using the application program, it is not necessary that all application programs on the terminal are adjusted by using the adjustment method of the embodiment, and only a specific application program needs to be adjusted by using the adjustment method of the embodiment, and the application program that needs to be adjusted is added to the brightness adjustment white list. For example, if a user needs a customary display brightness when watching a video, an application program related to video playing can be configured in the brightness adjustment white list.
In this step, it is determined whether the target application is one of the applications in the brightness adjustment whitelist. If yes, go to step 520; if not, go to step 530.
And step 520, reading a pre-stored configuration table to adjust the display brightness of the terminal to the target display brightness according to the preset brightness difference and the first display brightness.
In this step, if the target application is one of the applications in the brightness adjustment white list, reading a pre-stored configuration table, so as to adjust the display brightness of the terminal according to the preset brightness difference value and the first brightness difference value. The step of how to obtain the preset brightness through the configuration table may refer to the description of any of the above embodiments, and the embodiment is not limited thereto.
In this step, if the target application is not one of the applications in the brightness adjustment white list, the display brightness of the terminal is adjusted to the first display brightness.
In this embodiment, before reading the configuration table, it is determined whether the target application is one of the applications in the brightness adjustment white list, and if so, the configuration table is obtained, thereby avoiding wasting effort by directly searching the target application identifier from the configuration table. In addition, different application programs can be configured into the white list according to needs by adjusting the white list through the brightness, and compatibility is achieved.
In one embodiment, only step 510 to step 520 may be included.
It will be appreciated that the blacklist may also be used, and applications that do not require tuning may be configured into the blacklist.
It should be noted that, since the user does not necessarily perform the display brightness adjustment only once during the use of the target application, the configuration table needs to be updated by continuously detecting the latest display brightness adjusted by the user. In one embodiment, the method for adjusting display brightness of the present embodiment further includes:
continuously detecting the adjustment operation of manually adjusting the display brightness of the user in the process of using the target application by the user;
and when the adjustment operation of the user is detected, storing the difference value between the latest display brightness adjusted by the user and the second display brightness and the application identifier corresponding to the target application into the configuration table in an associated manner.
The adjustment operation is an operation of manually adjusting the display brightness by the user. If the adjustment operation of the user is detected, the difference value between the latest display brightness adjusted by the user and the second display brightness is used as the latest preset brightness difference value, so that the latest preset brightness difference value and the target application identifier are stored in the configuration table in an associated mode, the preset brightness difference value in the configuration table is updated, the preset brightness difference value is made to be consistent with the habit of the user as much as possible, and the accuracy of the adjustment of the display brightness is guaranteed.
It is to be understood that, before storing the difference between the latest display brightness adjusted by the user and the second display brightness and the application identifier association corresponding to the target application into the configuration table, it may also be determined whether the target application is one of the brightness adjustment white lists, and if so, the difference between the latest display brightness adjusted by the user and the second display brightness and the application identifier association corresponding to the target application are stored into the configuration table.
Before storing the difference value between the latest display brightness adjusted by the user and the second display brightness and the application identifier corresponding to the target application in the configuration table in an associated manner, determining whether the target application is one of the applications in the brightness adjustment white list, and if so, storing the difference value between the latest display brightness adjusted by the user and the second display brightness and the application identifier corresponding to the target application in the configuration table in an associated manner, so that the data volume occupied by the configuration table can be reduced, and the time for searching the preset brightness difference value is also reduced.
Referring to fig. 6, fig. 6 is a flowchart illustrating another method for adjusting display brightness according to an embodiment. The embodiment is suitable for the scene that the display brightness of the terminal is adjusted to the target display brightness after the unification of the user. In one embodiment, as shown in fig. 6, another method for adjusting display brightness is provided, which includes steps 610 to 640.
This step may refer to the description of any of the above embodiments, which is not repeated herein.
And step 620, prompting a user whether to adjust the display brightness of the terminal to the target display brightness.
In this step, the manner of prompting the user includes, but is not limited to, voice prompt, pop-up box prompt, etc., and is not limited herein. For example, if the user performs the frame flipping prompt, the user may be prompted whether to adjust the display brightness or not by displaying a word such as "whether to adjust the display brightness to the brightness manually adjusted last time" on the terminal; if through voice prompt, then can whether adjust the user through voice broadcast "whether will show brightness adjustment to the brightness of last manual adjustment" sound such as.
In this step, if the user selects adjustment, the display brightness of the terminal is adjusted to the target display brightness according to the preset brightness difference value and the first display brightness difference value.
And step 640, responding to the result that the user selects not to adjust, clearing the corresponding relation between the application identifier corresponding to the target application and the brightness difference value in the configuration table, and adjusting the display brightness of the terminal to the first display brightness.
In this step, if the user chooses not to adjust, the corresponding relationship between the application identifier corresponding to the target application and the brightness difference value in the configuration table is cleared, and the display brightness of the terminal is adjusted to the first display brightness. By clearing the corresponding relation between the application identifier corresponding to the target application and the brightness difference value in the configuration table, the data volume occupied by the configuration table can be reduced.
In one embodiment, the method for adjusting the display brightness may include only steps 610 to 630.
Referring to fig. 7, fig. 7 is a schematic view of a scenario for prompting a user whether to adjust according to an embodiment. In one embodiment, as shown in fig. 7, if the user selects "√" then the display brightness of the terminal is adjusted to the target display brightness based on the preset brightness difference and the first display brightness difference; and if the user selects the x, clearing the corresponding relation between the application identifier corresponding to the target application and the brightness difference value in the configuration table, and adjusting the display brightness of the terminal to the first display brightness.
The following describes how to adjust the display brightness of the terminal to the target display brightness according to the preset brightness difference and the first display brightness.
In one embodiment, the step 220 of adjusting the display brightness of the terminal to the target display brightness according to the preset brightness difference and the first display brightness includes:
and taking the sum of the preset brightness difference value and the first display brightness as the target display brightness, and adjusting the display brightness of the terminal to the target display brightness.
In this embodiment, for example, the first display brightness is L3, and the preset brightness difference is Δ L, then the target display brightness is L3+ Δl.
It can be understood that, the target display brightness of the embodiment is a sum of the display brightness and a preset brightness difference, and even if the difference between the first light intensity of the periphery when the user exits the application and the second light intensity of the periphery when the user reenters the application is larger, the accuracy of the display brightness adjustment can be further improved by determining the target display brightness adjustment mode through the preset brightness difference.
In one embodiment, the step 220 of adjusting the display brightness of the terminal to the target display brightness according to the preset brightness difference and the first display brightness includes:
determining a target brightness difference value according to the preset brightness difference value, wherein the target brightness difference value is the product of the preset brightness difference value and a weight factor, the weight factor is positively correlated with an automatically configured brightness difference, and the automatically configured brightness difference is the difference value between the first display brightness and the second display brightness;
and taking the sum of the target brightness difference and the first display brightness as the target display brightness, and adjusting the display brightness of the terminal to the target display brightness.
Illustratively, the weighting factor is 1+ (L3-L1)/L3, and the target display luminance is [1+ (L3-L1)/L3] × Δ L + L3, where L3 represents the first display luminance, L1 represents the second display luminance, and Δ L represents the preset luminance difference.
In this embodiment, the target brightness difference is determined according to the preset brightness difference, so that the sum of the target brightness difference and the first display brightness is used as the target display brightness, and the obtained target display brightness refers to the difference between the first display brightness and the second display brightness, so that even if the difference between the peripheral second light intensities is large when the user reenters the application, the final target display brightness can be compensated to a certain extent, and the display brightness adjustment accuracy is further improved.
In one embodiment, the step 220 of adjusting the display brightness of the terminal to the target display brightness according to the preset brightness difference and the first display brightness includes:
determining whether a first brightness difference value corresponding to the first display brightness exists in the target application;
if so, taking the first brightness difference value as the preset brightness difference value;
and if the preset brightness difference value does not exist, taking one of other brightness difference values as the preset brightness difference value, wherein the other brightness difference values are brightness difference values except the first brightness difference value in the brightness difference values corresponding to the target application.
In this embodiment, because the light intensity around the terminal may affect the viewing experience of the user, for the same application program, if the light intensity around the terminal is different, the brightness manually adjusted by the user is different, and the corresponding preset brightness difference values are different, that is, for the same application program, the preset brightness difference values corresponding to different light intensities around the terminal are also different. Therefore, when the display brightness of the terminal is adjusted, whether the target application has a first brightness difference value corresponding to the first display brightness is determined, if yes, the first brightness difference value is used as the preset brightness difference value, and the obtained target display brightness is more accurate. And if the brightness difference value does not exist, taking one of the other brightness difference values as the preset brightness difference value.
In one embodiment, taking one of the other luminance difference values as the preset luminance difference value includes:
acquiring second display brightness corresponding to each other brightness difference value;
determining a second brightness difference value between the second display brightness corresponding to each other brightness difference value and the first display brightness;
and taking the other brightness difference value corresponding to the minimum second brightness difference value as the preset brightness difference value.
In this embodiment, the second display brightness corresponding to each of the other brightness difference values is obtained, the second brightness difference value between the second display brightness corresponding to each of the other brightness difference values and the first display brightness is determined, and the other brightness difference value corresponding to the smallest second brightness difference value is used as the preset brightness difference value, so that the obtained preset brightness difference value is more accurate.
In one embodiment, the step of obtaining the second display brightness corresponding to each of the other brightness difference values may be obtained by a configuration table. Specifically, the brightness difference obtained by each manual adjustment by the user and the corresponding second display brightness are stored in the configuration table in an associated manner, so that the second display brightness corresponding to each other brightness difference can be obtained through the configuration table. Illustratively, the configuration table may be referred to as follows:
| application identification | Automatically configured display brightness | Difference in brightness |
| L31 | △L11 | |
| L32 | △L12 |
Illustratively, if the second display is displayedIf the luminance L31 is consistent with the first display luminance L1, Δ L will be11As a preset brightness difference value; if the L31 and the L32 are not consistent with the first display luminance L1, the difference between L31 and L1 and the difference between L32 and L1 are calculated respectively, and the luminance difference corresponding to the minimum difference is taken as the preset luminance difference. For example, if the difference between L31 and L1 is less than the difference between L32 and L1, Δ L will be11As a preset luminance difference value.
In one embodiment, optionally, one of the other luminance difference values is used as the preset luminance difference value, and the last stored luminance difference value may also be used as the preset luminance difference value.
It is understood that if one of the other luminance difference values is taken as the preset luminance difference value, the setting may be performed as needed, and the embodiment is not limited.
It should be understood that although the various steps in the flowcharts of fig. 2, 4-6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 4-6 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
