Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," and the like in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Further, as used herein, "and/or" means at least one of the connected objects, e.g., a and/or B and/or C, means 7 cases including a alone, B alone, C alone, and both a and B present, B and C present, both a and C present, and A, B and C present.

The screen brightness adjusting method provided by the embodiment of the invention can be applied to a mobile terminal at least comprising a first screen so as to adjust the brightness of the first screen. In practical applications, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.

The screen brightness adjusting method according to the embodiment of the present invention is explained below.

Referring to fig. 1, fig. 1 is a flowchart of a screen brightness adjusting method according to an embodiment of the present invention. As shown in fig. 1, the screen brightness adjusting method may include the steps of:

step 101, obtaining an environment brightness value of an environment where the mobile terminal is located, motion information of the mobile terminal, and display information of the first screen.

For the environment brightness value of the environment where the mobile terminal is located, the mobile terminal may be detected by the light sensor, but is not limited thereto.

The motion information of the mobile terminal may include at least one of: the moving speed, the walking steps within a first preset time length and the moving track within a second preset time length. The first preset time length and the second preset time length may be equal or different.

The display information of the first screen may be represented as, but is not limited to, application information running in the foreground of the first screen.

In a specific implementation manner, the mobile terminal may obtain the information according to a preset frequency to adjust the brightness of the screen.

In another implementation manner, the obtaining of the environment brightness value of the environment where the mobile terminal is located, the motion information of the mobile terminal, and the display information of the first screen includes:

acquiring an environment brightness value of an environment where the mobile terminal is located, motion information of the mobile terminal and display information of the first screen under the condition that target information changes;

wherein the target information comprises at least one of: the environment brightness value of the environment where the mobile terminal is located, the display information of the first screen, and the motion information of the mobile terminal.

In the embodiment of the invention, the mobile terminal adjusts the brightness of the first screen by combining the environment brightness value of the environment where the mobile terminal is located, the motion information of the mobile terminal and the display information of the first screen. Therefore, in this implementation, the mobile terminal may acquire the target information when detecting that the information changes. Therefore, compared with the method that the mobile terminal acquires the information according to the preset frequency, the method can reduce the frequency of the mobile terminal in executing the acquisition operation under the condition that the screen brightness adjustment meets the user requirement, and further can reduce the power consumption of the mobile terminal.

And step 102, determining a target brightness value according to the environment brightness value, the motion information and the display information.

In specific implementation, the mobile terminal may determine a brightness gain value according to the motion information and the display information, and further determine a target brightness value according to the environment brightness value and the brightness gain value.

Step 103, adjusting the brightness of the first screen to the target brightness value.

In a specific implementation manner, in an embodiment, the mobile terminal may adjust the brightness of the first screen to the target brightness value immediately after determining the target brightness value.

However, in some cases, such as frequent switching of applications, and fast change of ambient light, if the brightness is adjusted too fast, the screen brightness may change fast, and therefore, the screen may be flickered.

In order to reduce the phenomenon of screen splash, the specific implementation can be realized in at least the following two ways.

In a first manner, after determining the target brightness value, the mobile terminal may wait for a preset delay time period T0 to adjust the brightness of the first screen to the target brightness value, so that if it is detected again that the trigger condition is met within the preset delay time period T0 and a new target brightness value is determined, the mobile terminal may adjust the brightness of the first screen to the new target brightness value, thereby reducing the screen flicker phenomenon in a manner of delaying adjustment of the screen brightness.

In a second mode, optionally, the adjusting the brightness of the first screen to the target brightness value includes:

adjusting the brightness of the first screen to the target brightness value according to a preset mode;

in the preset mode, a brightness adjustment value and a brightness adjustment duration satisfy an exponential function relationship, and the brightness adjustment value is an absolute value of a difference value between the target brightness value and a current brightness value of the first screen.

In the second mode, in the process of adjusting the brightness of the first screen to the target brightness value, the brightness adjustment value and the brightness adjustment duration satisfy an exponential function relationship, and for convenience of understanding, please refer to fig. 2 together. In fig. 2, the brightness adjustment time period is set to 2 seconds(s), and the brightness adjustment value is set to 100. As can be seen from fig. 2, the brightness adjustment speed is slow first and then fast within the brightness adjustment duration, so that sudden changes of the screen brightness can be avoided, and the screen flashing phenomenon can be reduced.

According to the screen brightness adjusting method, the mobile terminal adjusts the screen brightness by combining the environment brightness value of the environment where the mobile terminal is located, the motion information of the mobile terminal and the display information of the first screen, so that the reliability of screen adjustment can be improved, and the screen brightness adjusting effect is further improved.

It should be noted that, if the mobile terminal includes other screens besides the first screen, the mobile terminal may adjust the other screens by using the screen brightness adjusting method according to the embodiment of the present invention.

For example, it is assumed that the mobile terminal includes a first screen and a second screen, and both the first screen and the second screen are in an operating state.

If the target information triggering the screen brightness adjustment is as follows: the environment brightness value of the environment where the mobile terminal is located, and/or the motion information of the mobile terminal, the mobile terminal may adjust the brightness of the first screen in combination with the environment brightness value of the environment where the mobile terminal is located, the motion information of the mobile terminal, and the display information of the first screen; and adjusting the brightness of the second screen by combining the environment brightness value of the environment where the mobile terminal is located, the motion information of the mobile terminal and the display information of the second screen.

If the target information triggering the screen brightness adjustment is as follows: the display information of the first screen does not include the display information of the second screen, which indicates that the display information of the second screen is not changed, so that the mobile terminal can only adjust the brightness of the first screen without adjusting the brightness of the second screen.

If the target information triggering the screen brightness adjustment is as follows: and detecting the display information of the second screen, wherein the target information does not include the display information of the first screen, which indicates that the display information of the first screen is not changed, so that the mobile terminal can only adjust the brightness of the second screen without adjusting the brightness of the first screen.

In this embodiment of the present invention, optionally, the determining a target brightness value according to the environment brightness value, the motion information, and the display information includes:

determining a target brightness gain value according to the motion information and the display information;

acquiring a target gain coefficient corresponding to the environment brightness value;

determining a target brightness value according to the environment brightness value and the target value;

wherein the target value is a product of the target brightness gain value and the target gain system.

In a specific implementation, the mobile terminal may determine the target brightness gain value according to the motion information and the display information in a plurality of ways, which is specifically described as follows:

the first method, determining a brightness gain value according to the motion information and the display information, includes:

determining a target scene where the mobile terminal is located according to the motion information;

acquiring a first sub-brightness gain value corresponding to the target scene;

determining a target operation scene of the first screen according to the display information;

acquiring a second sub-brightness gain value corresponding to the target operation scene;

and determining a target brightness gain value according to the first sub-brightness gain value, the second sub-brightness gain value, a first weight coefficient corresponding to the first sub-brightness gain value and a second weight coefficient corresponding to the second sub-brightness gain value.

In the method, the motion information of the mobile terminal can be used for determining the scene (such as walking, running, driving, indoor and the like) of the mobile terminal. The display information of the first screen can be used to determine the operation scene of the first screen (such as watching video, navigating, browsing web pages, talking, reading, etc.).

For the acquisition of the first sub-brightness gain value, the mobile terminal may pre-store a first corresponding relationship between the motion information of the mobile terminal and the scene, and a second corresponding relationship between the scene and the sub-brightness gain value. In this way, after the mobile terminal acquires the motion information, the first sub-brightness gain value corresponding to the target scene can be acquired directly by searching the first corresponding relationship and the second corresponding relationship.

For ease of understanding, examples are illustrated below:

the expression of the first correspondence relationship may refer to fig. 3, and the expression of the second correspondence relationship may refer to fig. 4a and 4 b.

In fig. 3, the motion information of the mobile terminal includes: the movement speed, the walking step number of 2s and the movement track within 10 s; the scene comprises the following steps: walking, running, driving, and indoors.

When the method is implemented, the mobile terminal can determine whether the moving mode of the user is leg leaning or transportation according to the steps per 2 seconds, and if the user is leg leaning, the mobile terminal distinguishes whether to walk or run according to the steps and the speed; if the vehicle is driven, whether the vehicle is driven or not is determined through the speed and the moving track.

In fig. 4a and 4b, the scene includes: walking, running, driving, and indoors. The difference between fig. 4a and fig. 4b is that: in fig. 4a, the walking scene corresponds to a sub-luminance gain value of 30, and the running scene corresponds to a sub-luminance gain value of 20; in fig. 4b, the walking scene corresponds to a brightness gain range of 25-30, and the running scene corresponds to a sub-brightness gain range of 20-25.

In addition, in fig. 4a and 4b, the sub-luminance gain value corresponding to the driving scene is 30; the sub-luminance gain value corresponding to the indoor scene is-20.

As for fig. 4a, each scene corresponds to a sub-brightness gain value, so that after the mobile terminal determines the target scene where the mobile terminal is located, the mobile terminal can obtain the first sub-brightness gain value corresponding to the target scene by looking up the corresponding relationship in fig. 4 a.

As for fig. 4b, since the walking scene and the running scene respectively correspond to a sub-luminance gain range, if the mobile terminal determines that the target scene is the walking scene or the running scene, it is further required to determine a sub-luminance gain value from the corresponding scene as the first sub-luminance gain value.

Optionally, the obtaining a first sub-brightness gain value corresponding to the target scene includes:

acquiring the movement speed in the movement information;

and determining a first sub-brightness gain value corresponding to the movement speed from a target sub-brightness gain range corresponding to the target scene.

In this embodiment, the mobile terminal may further pre-store a correspondence between the motion speed and the sub-luminance gain value, and further may determine the sub-luminance gain value corresponding to the motion speed as the first sub-luminance gain value from a target sub-luminance gain range corresponding to the target scene.

In a specific implementation, in the corresponding relationship between the motion speed and the sub-luminance gain value, the motion speed and the sub-luminance gain value are inversely related, that is, the faster the motion speed is, the smaller the sub-luminance gain value is.

In one implementation, the correspondence between the motion speed and the sub-luminance gain value can be determined by the following formula: IN_SCE-2.5 · S + 32.5. Further, IN_SCEAn integer may be taken. Wherein, the S tableIndicating the speed of movement, IN_SCERepresenting the sub-luminance gain values.

It should be understood that the sub-luminance gain values corresponding to each scene in fig. 4a and 4b are only examples, and are empirical values, and the following describes the setting of the sub-luminance gain values corresponding to each scene in fig. 4 a:

for a walking scene, the probability of operating the mobile phone is relatively low during walking, and certain potential safety hazards exist. When a user needs to acquire information from a mobile phone screen, if the content of the screen is difficult to identify by eyes of the user due to too low brightness, the potential safety hazard is deepened. Therefore, in a walking scene, its corresponding sub-luminance gain value may be set to 30.

The running scene is similar to the walking scene, but considering that the user runs in a dark environment, the brightness gain is too high, the screen brightness is too glaring, the user can be blinded instantly, and the potential safety hazard is increased, so that the first sub-brightness gain can be reduced by 10 compared with the walking scene.

The brightness of a use scene under the driving condition needs to be enhanced to a certain degree, so that the situation that the driving safety is influenced by a driver who spends more energy on seeing a navigation picture clearly due to too dark is avoided.

The indoor light is relatively soft and is not in a moving posture generally, and the proper reduction of the brightness is beneficial to eye fatigue.

It should be understood that the correspondence relationships in fig. 3 and fig. 4a are merely examples, and the specific expressions of the parameters in the correspondence relationships are not limited thereby. The sub-luminance gain may have a value range of [ -100,100], but is not limited thereto.

For the acquisition of the second sub-brightness gain value, the mobile terminal may determine the target operation scene of the first screen according to the display information of the first screen. In specific implementation, the display information of the first screen may be represented as a type to which an application program running in the foreground of the first screen belongs, and the terminal may have a third corresponding relationship between the application program type and the running scene in advance, so that the mobile terminal may determine the target running scene of the first screen after acquiring the display information of the first screen.

For example, in the third correspondence, the game application may correspond to a game running scene; the video application program can correspond to a video running scene; the chat application may correspond to a chat scenario; the reading application program can correspond to a reading running scene; the navigation application may correspond to a navigation scenario, etc.

The mobile terminal may further pre-store a fourth corresponding relationship between the operation scene and the sub-brightness gain value. In this way, after the mobile terminal determines the target operation scene, the sub-brightness gain value corresponding to the target operation scene can be determined as the second sub-brightness gain value directly by searching the fourth corresponding relation.

For ease of understanding, examples are illustrated below:

the expression of the fourth correspondence relationship may refer to fig. 5. In fig. 5, the operational scenario (which may also be referred to as a function) includes: video, navigation, web page, chat, standby, talk, read, lighting.

And (5) viewing a screen operation scene. The video is an artistic work of light and shadow, and many detailed contents can depict more details through the gorgeous degree of colors, the contrast of light and shade and the like. Therefore, the sub-brightness gain value of the video scene is greatly improved for better restoring the content details, especially the dark details.

And navigating the operation scene. The navigation scene is relatively complicated, especially driving navigation, because the change of external environment light leads to the cell-phone screen luminance to change sharply, and human eye adaptation speed can not catch up again, can bring very big visual difficulty to the user, even bigger potential safety hazard. Therefore, in the navigation scene, a larger sub-brightness gain value is set, the influence of ambient light on the screen brightness is reduced, and the brightness change in the navigation scene is more reasonable and safer.

The web browsing has videos, characters and pictures, the brightness is properly improved for better restoring the details of the pictures and the videos, and the situation that the brightness is too high and dazzling is avoided under the condition of white background and black characters exists.

Under the chat environment, characters are more, pictures are gathered less, the brightness is slightly improved, and the viewing experience of the pictures is improved to a certain extent.

The brightness is properly reduced during the call, but cannot be reduced too low, so that the operation of the call interface is influenced.

In a reading scene, the reading device is generally static, is not rich in colors, and is easy to fatigue eyes. Therefore, the sub-brightness gain value is set to-15, the stimulation of light to eyes is reduced, and the recognition rate of characters is also ensured.

The lighting scene is that the flash lamp is used for lighting the surrounding environment, and at the moment, more sub-brightness gain values for reducing the screen brightness are beneficial to enlarging the pupils of the eyes of the user and seeing the surrounding dark environment more clearly.

It should be understood that the correspondence relationship in fig. 5 is merely an example, and the concrete expression form of each parameter in the correspondence relationship is not limited thereby. The sub-luminance gain may have a value range of [ -100,100], but is not limited thereto.

In this manner, the mobile terminal may determine a sum of a first product and a second product as the target brightness gain value, wherein the first product is a product of the first sub-brightness gain value and the first weight coefficient, and the second product is a product of the second sub-brightness gain value and the second weight coefficient.

It should be understood that the present invention is not limited to the specific values of the first weighting factor and the second weighting factor, and the specific values can be determined according to actual requirements. For example, in one implementation, the first weighting factor and the second weighting factor may be determined to be 1, that is, the mobile terminal may directly determine the sum of the first sub-luminance gain value and the second sub-luminance as the target luminance gain value. In another implementation, the sum of the first weight coefficient and the second weight coefficient may be defined as 1.

Mode two

Acquiring a third sub-brightness gain value corresponding to the motion information and a fourth sub-brightness gain value corresponding to the display information;

and determining the target brightness gain value according to the third sub-brightness gain value, the fourth sub-brightness gain value, a third weight coefficient corresponding to the third sub-brightness gain value and a fourth weight coefficient corresponding to the fourth sub-brightness gain value.

In this manner, the mobile terminal may pre-store a fifth corresponding relationship between the motion information and the third sub-luminance gain value, and a sixth corresponding relationship between the display information and the fourth sub-luminance gain value. In this way, after the mobile terminal acquires the motion information and the display information, the mobile terminal may directly acquire the third sub-brightness gain value and the fourth sub-brightness gain value by searching the fifth corresponding relationship and the sixth corresponding relationship.

In the second mode, "the target brightness gain value is determined according to the third sub-brightness gain value, the fourth sub-brightness gain value, the third weight coefficient corresponding to the third sub-brightness gain value, and the fourth weight coefficient corresponding to the fourth sub-brightness gain value" may be the same as the specific expression form of "the target brightness gain value is determined according to the first sub-brightness gain value, the second sub-brightness gain value, the first weight coefficient corresponding to the first sub-brightness gain value, and the second weight coefficient corresponding to the second sub-brightness gain value" in the first mode, "which may refer to the above description, and thus, the description is omitted here.

Compared with the first mode and the second mode, the target scene corresponding to the motion information does not need to be determined, and the target operation scene corresponding to the information is displayed, so that the rate of determining the target brightness gain value can be improved.

In specific implementation, the mobile terminal may obtain the target gain coefficient corresponding to the environment brightness value in a plurality of ways.

In one mode, the mobile terminal may pre-store a corresponding relationship between the environment brightness value and the gain coefficient, so as to determine the target gain coefficient corresponding to the environment brightness value directly by searching the corresponding relationship.

In another mode, the mobile terminal may pre-store a calculation formula of the gain coefficient f:

wherein, IN_LSRepresenting the ambient brightness value.

IN_LSIn the range of 0 to 100, of fThe variation is the upper half of the sinusoid as shown in figure 6. As can be seen from FIG. 6, IN_LSFrom 50 to 0, or from 50 to 100, the gain factor tapers off; IN_LSAt 0 and 100, the gain factor is 0.

It should be noted that the above calculation formula is only an example, and the relationship between the ambient brightness value and the gain coefficient is not limited thereby.

In a specific implementation, the mobile terminal may determine the target brightness value according to the environment brightness value and the target value in a plurality of ways.

In one manner, the mobile terminal may directly determine the sum of the ambient brightness value and the target brightness value as the target brightness value. In another mode, the mobile terminal may set a third weight c and a fourth weight d in advance for the environment luminance value, where c + d is 1, so that the target luminance value is c × environment luminance value + d × target value. Of course, the above-mentioned manner is only an example, and the present invention is not limited to the concrete expression of "determining the target brightness value according to the environment brightness value and the target value".

It should be noted that, the various alternative embodiments described above may be implemented in combination with each other or separately, and the embodiments of the present invention are not limited thereto.

For example, in one embodiment, the screen brightness calculation implementation principle is: on the basis of the ambient brightness value obtained by the light sensor, the function gain (i.e. the operation scene gain of the above contents) and the scene gain are increased to perform brightness compensation.

The main calculation formula is as follows:

B＝IN_LS+f(IN_FUN+IN_SCE)

wherein, B is a target brightness value, B belongs to [0,100], if the calculation result is more than 100,100 is selected, and if the calculation result is less than 0, 0 is selected;

IN_LSindicating the ambient brightness value, IN, detected by the sensor_LS∈[0,100]；

IN_FUNRepresenting the functional gain value, IN_FUN∈[-100,100]A second sub-luminance gain value corresponding to the above;

IN_SCErepresenting a scene gain value, IN_SCE∈[-100,100]A first sub-luminance gain value corresponding to the above;

f represents a coefficient of the function gain and the scene gain, and f ∈ [0,1], corresponds to the gain coefficient described above.

Where f has the effect of controlling the intensity of the functional gain and scene gain versus sensor brightness compensation, 0 for compensation off, and 1 for intensity maximum.

Examples are:

in a burning sun, the sensor will send 100 values and the screen brightness should be adjusted to be brightest. At this time, if IN_FUN＝-20，IN_SCEIf f is equal to 1 and-10, then B is calculated to be 70, and the screen will be obscured in a strong light environment. At this time, we need to set the f value to 0, and turn off the compensation of the function gain and the scene gain to the photosensor.

IN the case of the navigation mode, f is set to 1, namely IN is used for driving at night _LS0, but two gains IN_FUN＝30，IN_SCE30, yielding B60. This is that the screen brightness is not so dark as to be very difficult to recognize, nor so bright as to be very obtrusive.

In practical applications, the correspondence of fig. 3, fig. 4a (or fig. 4b) and fig. 5 may be stored in a database. Specifically, the database may hold the following data: the method comprises the steps of automatically adjusting a brightness switch, a brightness value, a function gain (two data of a default gain and a personalized gain) and a scene gain (two data of the default gain and the personalized gain). The cases of environmental (i.e., the scenario of the foregoing) gains include: walking, running, driving, commuting, indoors; the cases of scene (i.e., the operational scenes of the foregoing) gains include: video, navigation, web page, chat, standby, talk, read, lighting.

As shown in fig. 7, in the case of a change in the target information, the brightness calculation system may be triggered to operate. At this time, the brightness calculation system may obtain an environment brightness value of an environment in which the mobile terminal is located, the motion information of the mobile terminal, and the display information of the first screen, read the configuration in the database, and determine a target brightness value of the first screen.

It should be noted that the sub-luminance gain values corresponding to the scenes in fig. 4a, 4b and 5 can be understood as the initial configuration. Since the requirements of different user groups for the screen brightness are different, the configuration of the sub-brightness gain value cannot be fixed, and the sub-brightness gain value needs to be dynamically configurable.

Optionally, before determining the brightness gain value according to the motion information and the display information, the method further includes:

updating at least one of the first sub-luminance gain value and the second sub-luminance gain value if a trigger condition is satisfied;

wherein the meeting of the trigger condition comprises at least one of:

receiving screen brightness configuration information of a server;

and detecting that the brightness value of the first screen is adjusted in the target scene and the target operation scene by the user.

In the embodiment of the invention, the mobile terminal can dynamically configure the sub-brightness gain value in two ways, one is remote configuration of the server, and the other is personalized configuration. The server is remotely configured in such a way that the latest configuration information is pushed by the server under the condition of networking of the devices. The customized configuration is that when the current brightness is not satisfied by the user, the brightness can be manually adjusted to achieve a satisfactory effect. At the moment, the system updates the current operation scene of the mobile terminal and the sub-brightness gain value of the scene where the mobile terminal is located currently and stores the sub-brightness gain value as personalized configuration information. When the system reads the sub-brightness gain value, the personalized configuration is preferentially used, and if the personalized configuration does not have the response function or the sub-brightness gain value of the scene, the default configuration is used. As shown in fig. 8, the mobile terminal may read the personal configuration in the presence of the personal configuration when reading the configuration of the database; and if the personal configuration does not exist, reading the default configuration and determining the target brightness value.

And optimizing the server configuration. The server has a continuously iterative and refined configuration, and each time there is an improvement, the configuration is pushed to each terminal to replace the original default configuration. Therefore, the user experience effect can be continuously improved. The process of configuring and adjusting the server is simple, the configuration file is pushed to the mobile terminal through the network, and then the original configuration file is replaced.

On the other hand, local customized tuning. The sensitivity to light and the requirements are different according to different users. User dissatisfaction and inadaptation to the brightness scheme of the current system configuration may occur, and the user may turn off the automatic brightness adjustment and perform manual brightness adjustment. At this time, after the user adjusts the brightness, the brightness becomes an input variable for system tuning, and a user personal configuration scheme is generated to supplement the system configuration scheme.

As an addition to the default configuration, the personal configuration is a special scenario added by the user. The scene trigger is calibrated by a plurality of subdivision environment parameters, and once the scene is reproduced, the brightness configuration reads the configuration scheme information. Calibrating parameters: time, location, environment, motion status, etc. This special scenario can be considered as a special case, not affected by the luminance calculation of the system. Such as: in the 'driving' + 'navigation' mode, the gain is +60 brightness, but a certain user thinks that the navigation can hear the sound, the screen brightness is too high, electricity is consumed, the screen brightness is actively reduced, a special scene of the user is created at the moment, and information such as the current time, the current position, an external scene, a use scene, a motion state and the like is stored. If there is a day that is very close to this special scene, the brightness configuration will use the special scene, and the brightness of the special scene is not configured according to the calculated gain any more.

For a scene that receives the screen brightness configuration information of the server, the mobile terminal may update the sub brightness gain value indicating the update in the configuration information.

And adjusting the brightness value of the first screen for the scene in which the user is detected in the target scene and the target running scene.

IN specific implementation, the formula B is equal to IN_LS+f(IN_FUN+IN_SCE) Known as IN_FUN+IN_SCE＝(B－IN_LS) IN this scenario, IN_LSAnd f are not changed, therefore, the mobile terminal can calculate IN according to the screen brightness adjusted by the user_FUN+IN_SCE. The mobile terminal may then derive IN from the calculation_FUN+IN_SCEUpdating at least one of the first sub-luminance gain value and the second sub-luminance gain value.

IN before update_FUNIs IN_FUN1IN before update_SCEIs IN_SCE1Updated IN_FUNIs IN_FUN2Updated IN_SCEIs IN_SCE2Calculated IN_FUN+IN_SCEIs P.

IN one implementation, the mobile terminal may calculate the updated IN according to the following calculation formula_FUNIs IN_FUN2And updated IN_SCEIs IN_SCE2：

IN_FUN2＝IN_FUN1×P/(IN_SCE1+IN_FUN1)；

IN_SCE2＝IN_SCE1×P/(IN_SCE1+IN_FUN1)。

IN another implementation, the mobile terminal may maintain IN_FUNUpdate IN only, unchanged_SCEExemplary, IN_SCE2＝IN_SCE1+(P－(IN_SCE1+IN_FUN1))。

IN another implementation, the mobile terminal may maintain IN_SCEUpdate IN only, unchanged_FUNExemplary, IN_FUN2＝IN_FUN1+(P－(IN_SCE1+IN_FUN1))。

It should be noted that the above implementation is only an example, and the present invention is not limited to the specific implementation of updating at least one of the first sub-luminance gain value and the second sub-luminance gain value.

Therefore, the flexibility of determining the sub-brightness gain value can be improved, and the brightness adjusting effect of the screen can be further improved.

In the embodiment of the present invention, the direct purpose of the screen brightness adjustment is two: 1. comfort of the user's eyes; 2. definition of screen content. Aiming at the first point, the brightness can be adjusted by capturing the size of the eye pupil of the user through the camera, when the pupil is shrunk, the light is too strong, otherwise, the light is too weak. Of course, the effect of ambient light is also taken into account.
