Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the related art, when the terminal in the automatic backlight mode is turned on, the light sensation value of the current environment can be continuously read from the light sensation device, and the currently required screen backlight brightness value is calculated according to the light sensation value, so that the function of automatically changing the screen backlight is realized according to the light sensation value.

The backlight brightness adjustment is carried out by adopting the automatic backlight mode, the backlight brightness adjustment is usually carried out by depending on the ambient light collected by the ambient light sensor, and under some special navigation scenes, the backlight brightness optimization is not thorough, for example, when a user drives a car, the terminal placing angle is shielded by a car body to the ambient light, so that the light sensing parameters collected by a fixedly arranged light sensor (such as a fixedly arranged front sensor and/or a rear sensor) are inaccurate, and the backlight brightness adjustment error is larger; for another example, in the riding navigation/walking navigation, the light sensation parameters collected by the light sensation sensors which are usually fixedly arranged are higher, and then the backlight brightness is very high during automatic adjustment, but in such a case, generally, the high backlight brightness is not needed in the terminal navigation process, and in addition, the temperature of the terminal is increased due to long-term storage of the high backlight brightness, so that the terminal can be damaged.

The present application will be described in detail with reference to specific examples.

In one embodiment, as shown in fig. 1, a screen brightness adjusting method is specifically proposed, which can be implemented by relying on a computer program and can run on a screen brightness adjusting device based on a von neumann system. The computer program may be integrated into the application or may run as a separate tool-like application.

The screen brightness adjusting apparatus may be a terminal having a screen brightness adjusting function, and the terminal includes but is not limited to: wearable devices, handheld devices, personal computers, tablet computers, in-vehicle devices, smart phones, computing devices or other processing devices connected to a wireless modem, and the like. Terminals can be called different names in different networks, for example: user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user equipment, cellular telephone, cordless telephone, Personal Digital Assistant (PDA), terminal equipment in a 5G network or future evolution network, and the like.

Specifically, the screen brightness adjusting method comprises the following steps:

step S101: and under the current environment, acquiring the backlight brightness of the screen.

In this embodiment, the terminal may pre-start the automatic backlight mode, based on the automatic backlight mode, the electronic device may automatically enable to acquire a light sensing parameter under the current environment based on the light sensor, calculate a currently required screen backlight brightness value, and then, in the automatic backlight mode, the electronic device may adjust the backlight brightness of the screen based on the calculated screen backlight brightness value; further, in the process of automatic backlight adjustment, in order to avoid that the backlight brightness after automatic backlight adjustment is not matched with the actual navigation application scene in the navigation scene corresponding to the navigation mode, the terminal may perform secondary adjustment on the backlight brightness of the screen in combination with the navigation mode, and in the process of secondary adjustment, the terminal may perform fine adjustment on the current backlight brightness. I.e. the step of step S103 is performed.

Step S102: and acquiring a current navigation mode, and controlling at least one light sensor contained in the navigation mode to acquire light sensing parameters of the current environment based on the navigation mode.

The navigation mode is associated with a current navigation state of the terminal, and common navigation states can be driving navigation, riding navigation, walking navigation, bus navigation, subway navigation and the like.

In practical application, the terminal screen brightness adjustment usually adopts an automatic backlight technology, collects light sensation parameters based on a light sensor (such as an ambient light sensor), and calculates the currently required screen backlight brightness value according to the light sensation value, thereby realizing the function of automatic screen backlight change according to the light sensation value.

In this embodiment, the terminal is previously started with an automatic backlight mode, and then the required screen backlight brightness value is calculated in the automatic backlight mode, so that the screen backlight automatic change is realized according to the light sensation value, meanwhile, the terminal acquires the backlight brightness of the screen, so that in order to avoid the backlight brightness after the automatic backlight adjustment from being mismatched with an actual navigation application scene, the terminal can determine the current navigation mode, and based on the actual navigation scene corresponding to the navigation mode, the light sensation parameters of the current environment are collected in real time or periodically by controlling the corresponding light sensor corresponding to the navigation mode.

Specifically, the terminal determines a current navigation mode, and controls a related light sensor to acquire light sensing parameters of the current environment based on the corresponding navigation mode. In this embodiment, the terminal may include a plurality of photo sensors, as shown in fig. 2, fig. 2 is a schematic view of a terminal photo sensor distribution scenario, in fig. 2, the terminal is configured with a top photo sensor disposed on the top of a terminal housing, a front photo sensor disposed on the front side of the terminal, and a rear photo sensor disposed on the back side of the terminal, and in navigation scenarios corresponding to different navigation modes, different photo sensors may be controlled to perform photo parameter collection, so as to avoid accurate measurement of photo parameters based on part of the photo sensors in corresponding navigation scenarios, avoid interference of photo parameters collected by other photo sensors, and avoid a situation that the temperature of the whole terminal is high when the number of photo sensors working simultaneously is large, for example, in a riding or walking scenario, the terminal may only control the front photo sensor to collect photo parameters in the current environment, and a rear or top light sensor is not required to be controlled for collection. Therefore, the situation that in the related technology, the light sensation parameters are collected based on a fixed mode can be avoided, if any time, the preposed light sensors are controlled to collect in the related technology, and if any time, all the light sensors are controlled to collect in the related technology. Therefore, the light sensors are intelligently controlled to collect light sensation parameters based on actual scene requirements corresponding to the navigation modes in different navigation modes, wherein the light sensors can be one or more, specifically can be light sensors, namely brightness sensors, and are used for detecting the light intensity of the environment and converting the light intensity into electric signals to be sent to the processor contained in the terminal connected with the light sensors.

In specific implementation, the terminal may store mapping relationships between different navigation modes and the light sensors, the mapping relationships may be represented in the form of a set, a chain table, and the like, after the terminal determines the current navigation mode, the terminal may directly determine the light sensor corresponding to the "current navigation mode" based on the mapping relationships, and then control the corresponding light sensor to acquire the light sensing parameters in the current environment based on at least one light sensor that needs to be controlled and called.

Step S103: and adjusting the backlight brightness of the screen based on the navigation mode and the light sensation parameters.

In this embodiment, the same navigation mode may correspond to different navigation scenes in practical application, for example, the same navigation mode may correspond to a daytime navigation scene or a nighttime navigation scene in the driving mode, and may correspond to an exposure scene (which may be understood as a strong ambient light) or a weak light scene in the walking or riding navigation mode. In practical application, each navigation scene corresponding to the navigation mode can be subdivided in advance based on the collected light sensation parameters (the number of the parameters can be multiple), the problem that the current backlight brightness in the automatic backlight mode has errors in different navigation scenes can exist, the terminal can determine a target navigation scene corresponding to the current navigation mode based on the scene judgment conditions aiming at different navigation scenes in the same navigation mode and the light sensation parameters, and then perform secondary adjustment on the current automatic backlight brightness based on the target navigation scene. In the embodiment, mainly for special navigation scenes in different navigation modes, relevant display requirements in the special navigation scenes are considered, and then secondary adjustment is performed on the current automatic backlight brightness.

For example, in an exposure scene in the walking/riding navigation mode, the backlight brightness of the terminal in the automatic backlight mode is usually too high, and considering that the external temperature and the current backlight brightness are too high, the terminal temperature is actually high, and a risk of terminal damage exists.

For example, in a daytime navigation scene in a driving navigation mode, a terminal can be placed on a support (such as a vehicle-mounted support), due to the relationship of the placement angle, the light sensation value acquired by a terminal light sensor is much lower than the ambient light intensity outside the vehicle (namely, the acquired ambient light has a larger error), so that the backlight brightness of the terminal based on the ambient light with a large error in an automatic backlight mode is lower, at the moment, the terminal needs to keep higher backlight brightness for navigation, and the current backlight brightness of a screen can be improved through secondary adjustment.

For example, in a night navigation scene in a driving navigation mode, the terminal can be placed on a support (such as a vehicle-mounted support), due to the relation of the placement angle, the real ambient light sensing value acquired by the light sensor is low, the low backlight brightness is not beneficial to safe driving of a user (namely, the acquired ambient light has a large error), and therefore the backlight brightness of the terminal based on the ambient light with a large error in an automatic backlight mode is low, at the moment, the terminal needs to keep the high backlight brightness for navigation, and the current backlight brightness of the screen can be improved through secondary adjustment. And so on.

Specifically, after the current navigation mode is determined, which type of navigation scene belongs to in the navigation mode is determined based on the light sensation parameters (which may be multiple), such as an exposure scene in the walking/riding navigation mode, a dim light scene in the walking/riding navigation mode, a daytime navigation scene in the driving navigation mode, a night navigation scene in the driving navigation mode, and the like.

In a possible implementation manner, a light sensation parameter range may be set in advance for each navigation scene in the navigation mode, where the light sensation parameter range may be a light sensation parameter range corresponding to light sensation parameters acquired at different parts, such as a light sensation parameter range of a front light sensor, a light sensation parameter range of a rear light sensor, and a light sensation parameter range of a top light sensor; judging whether the collected light sensation parameters of all parts respectively fall into a light sensation parameter range corresponding to a certain navigation scene in the navigation mode, if so, adjusting the backlight brightness of the current screen based on a secondary adjustment rule corresponding to the navigation scene in the navigation mode, and the method comprises the following steps:

the secondary adjustment rule may be: adjusting the backlight brightness of the current screen according to a preset fixed value, for example, reducing or increasing the backlight brightness of the current screen based on the preset fixed value;

the secondary adjustment rule may be: weighting all the acquired part light sensation parameters to obtain a weighted light sensation value, then acquiring a light sensation reference light sensation coefficient corresponding to a certain navigation scene in the navigation mode, calculating a product value of the reference light sensation coefficient and the weighted light sensation value, and then adjusting the backlight brightness of the current screen to the product value;

the secondary adjustment rule may be: and the terminal acquires the corresponding eye parameter under the current environment and determines the brightness adjustment value of the backlight brightness based on the eye parameter.

In a possible implementation, the following is to be interpreted in conjunction with a specific implementation scenario for a process of determining the brightness adjustment value of the backlight brightness based on the eye parameter in conjunction with the eye parameter corresponding to the current environment:

the eye parameter may be understood as a fitting of one or more of parameters such as an eye distance between the terminal and the user, an eye angle between the terminal and the user, and an eye distance between the user, and it may be understood that the eye parameter associated with the user in advance may affect the backlight brightness subjectively felt by the user to be lower or higher in the actual backlight display experience of the terminal due to a change in the eye parameter between the user and the terminal. Based on this, in some embodiments, the eye parameter corresponding to the current environment may be obtained in a specific scene corresponding to the navigation mode, for example, in the driving navigation mode, since the terminal is usually fixed on the support, the variation of the eye parameter is usually small, and a reference for secondary adjustment, such as obtaining the distance between the human eyes and the terminal, the area of the eyes, and the like, may be included.

As shown in fig. 3, for a point light source emitting visible light uniformly, the total power of light emission is P0, and assuming that the area of the eye is S and the distance of the eye from the point light source is R, the power received by the eye is P:

when the point source moves from O1 to position O2, the power received by the eye decreases with distance, resulting in a decrease in brightness perceived subjectively by the human eye.

In contrast, when the point light source is moved from O2 to position O1, the power received by the eye becomes larger as the distance becomes shorter, resulting in a decrease in the luminance subjectively perceived by the human eye.

In this embodiment, by presetting the corresponding reference power Q in the terminal navigation mode, where the reference power Q may be calculated and determined according to a corresponding power conversion formula based on the backlight brightness of the screen of the terminal, or calibrating the power values corresponding to different backlight brightness in advance, such as recording in a table form, the relative screen backlight brightness may be determined based on the power Q.

The terminal can acquire image data in the current environment through the included image sensor (such as a front camera, a structured light sensor, and the like), and then analyze the image data to extract corresponding eye parameters in the current environment, such as an eye distance R and an eye area S between the user and the terminal. In some embodiments, the individual change rate of the general eye area of each user is small, and the terminal may pre-store the general eye area corresponding to the user, that is, the eye area S does not need to be determined by the image sensor.

At this time, the terminal may calculate the reference total power P0 based on the reference power Q, the eye area S, and the eye distance R, derived based on the above formula,

then, the current reference backlight brightness is calculated according to the corresponding power conversion formula based on the reference power P0, and then the current backlight brightness of the screen is adjusted by the reference backlight brightness.

In addition, the eye angle a between the terminal and the user can be included in the secondary adjustment process, the terminal calculates the corresponding relation between the eye angle a and the angle influence factor b in a statistical manner by collecting sample data containing different eye angles in an actual application environment in advance, then calculates the power product value of the P0 and the influence factor b after the P0 is calculated, converts the current reference backlight brightness based on the power product value, and then adjusts the current backlight brightness of the screen to the reference backlight brightness.

In the embodiment of the application, a terminal obtains backlight brightness of a screen in a current environment, then obtains a current navigation mode, controls at least one light sensor contained in the terminal to acquire light sensing parameters of the current environment based on the navigation mode, and adjusts the backlight brightness of the screen based on the navigation mode and the light sensing parameters. By acquiring the backlight brightness in the current environment and then taking the navigation mode and the light sensation parameters into the reference for the optimal adjustment of the backlight brightness of the screen based on the light sensation parameters acquired by the corresponding light sensation devices in the current navigation mode, on one hand, the light sensation devices can be intelligently controlled to acquire the light sensation parameters based on the actual scene requirements corresponding to the navigation mode in different navigation modes; on the one hand, whether the terminal belongs to a special scene needing to optimize and adjust the backlight brightness in a certain navigation mode is determined based on intelligently acquired light sensation parameters and in combination with the navigation mode, so that the terminal can optimize and adjust the backlight brightness of the screen in the scene, the situation that the backlight brightness adjustment effect is poor in partial scenes due to the fact that the backlight adjustment is carried out on the ambient light acquired by the ambient light sensor in the related technology is avoided, the backlight optimization effect of the backlight adjustment is improved, and the accuracy of the backlight adjustment is improved.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another embodiment of a screen brightness adjusting method according to the present application. Specifically, the method comprises the following steps:

step S201: and under the current environment, acquiring the backlight brightness of the screen.

Specifically, refer to step S101, which is not described herein again.

Step S202: the current navigation mode is obtained.

Specifically, refer to step S102, which is not described herein again.

Step S203: and determining the navigation mode as a first navigation mode, and controlling the contained front light sensor to acquire a first light sensing parameter in the current environment.

Further, in this embodiment, in order to subdivide special scenes in different navigation modes, the current corresponding movement speed of the terminal is taken as a reference, and each navigation mode is at least divided into a first navigation mode with a slow movement speed and a second navigation mode with a fast movement speed.

Further, the terminal is provided with a speed threshold, the movement speed corresponding to the first navigation mode is smaller than or equal to the speed threshold, and the movement speed corresponding to the second navigation mode is larger than the speed threshold.

In some implementations, the first navigation mode may be a non-vehicle navigation mode, such as a cycling navigation mode, a walking navigation mode, and so forth, and the second navigation mode may be a vehicle navigation mode, such as a driving navigation mode.

Further, when the terminal is in the first navigation mode, such as in the riding and walking navigation modes, and when the terminal includes a plurality of sensors, the terminal may only control the front light sensor to acquire the light sensation parameters in the first navigation mode, that is, in the first navigation scene, the light sensation parameters may be accurately measured based on the front light sensor, so as to avoid interference of the light sensation parameters acquired by other light sensors and avoid a situation that the temperature of the whole terminal is high when the number of light sensors working simultaneously is large, for example, in the riding or walking scene, the terminal may only control the front light sensor to acquire the light sensation parameters in the current environment, and does not need to control the rear or top light sensor to acquire the light sensation parameters. In addition, the shielding of the front light sensor of the terminal is less in the first navigation mode, so that accurate light sensing parameters can be measured.

The front light sensors may be one or more in configuration, when the front light sensors are multiple, the front light sensors may form a light sensing array, and the light sensors may specifically be light sensors, that is, brightness sensors, for detecting the light intensity of the environment, and converting the light intensity into an electrical signal to be sent to a processor included in a terminal connected to the light sensors.

Step S204: determining that the navigation mode is a second navigation mode, controlling the included front light sensor to acquire the first light sensing parameter in the current environment, controlling the included rear light sensor to acquire the second light sensing parameter in the current environment, and controlling the included top light sensor to acquire the third light sensing parameter in the current environment;

further, when the terminal is in the second navigation mode, such as the driving navigation mode, in which the user of the terminal usually drives inside the vehicle, as shown in fig. 5, fig. 5 is a corresponding scene schematic diagram in the driving navigation mode, the terminal is placed on a support (vehicle-mounted support) as shown in fig. 5, and due to the relationship between the placement angle and the terminal fixing position, the terminal can control the front light sensor, the rear light sensor, and the top light sensor included therein to simultaneously collect light sensing parameters in the environment, and based on the light sensing parameters in each collection environment, it is determined more accurately whether the terminal is a special scene in the navigation mode, such as a scene a requiring backlight brightness adjustment during daytime navigation, and a scene b requiring backlight brightness adjustment during night navigation. It can be understood that in special scenes such as scene a and scene b, the light sensation values collected by the light sensors are usually controlled to be much lower than the ambient light outside the vehicle (i.e. the collected ambient light has a larger error).

Specifically, the terminal controls the contained front light sensor to work, so that the first light sensing parameter in the current environment can be acquired; controlling the included rear light sensor to work, and enabling the second light sensor parameter in the current environment to be collected; and controlling the included top light sensor to work, so as to collect the third light sensing parameter in the current environment.

Step S205: if the navigation mode is the first navigation mode, when the first light sensation parameter is larger than a first light sensation threshold value, the backlight brightness of the screen is reduced.

In practical application, in a first navigation mode corresponding to riding navigation/walking navigation and the like, generally acquired light sensation parameters are higher, and then backlight brightness during automatic adjustment is very high, but generally under the condition, high backlight brightness is not required in a terminal navigation process, and in addition, the temperature of the terminal is increased due to long-time storage of the high backlight brightness, so that the terminal is damaged. And so on.

In this embodiment, whether the terminal is in an exposure scene corresponding to the first navigation mode (i.e., the ambient light is high) is determined by setting a first light sensation threshold, where the first light sensation threshold is a threshold or a critical value of a first light sensation parameter. In practical application, the first light sensation threshold value may be preset before the terminal leaves a factory, or may be changed by a user of the terminal on a corresponding setting interface in a later use process.

Specifically, in an exposure scene in the first navigation mode, the backlight brightness of the terminal in the automatic backlight mode is usually too high, and considering that the external temperature and the current backlight brightness are too high, the terminal temperature is actually high, and a risk of terminal damage exists.

In a possible implementation manner, the terminal may adjust the backlight brightness of the current screen according to a preset fixed value (which may be understood as a brightness adjustment value corresponding to the exposure scene in the first navigation mode), such as reducing the backlight brightness of the current screen based on the preset fixed value.

In one possible embodiment, the terminal may obtain an eye parameter, such as an eyeball distance, between the terminal and the user in the current environment. Then, a brightness adjustment value of the backlight brightness is determined based on the eye parameter, and the backlight brightness of the current screen is reduced according to the brightness adjustment value.

In addition, when the first light sensing parameter is less than or equal to the first light sensing threshold, the backlight brightness of the current screen may not be adjusted.

Step S206: if the navigation mode is the second navigation mode, when the third light sensation parameter is greater than the first light sensation parameter and the third light sensation parameter is greater than the second light sensation parameter, the backlight brightness of the screen is improved.

In practical application, as shown in fig. 5, in a daytime navigation scene in a corresponding second navigation mode, such as driving navigation of a motor vehicle, a terminal is placed on a support (such as a vehicle-mounted support), due to the relationship of the placement angles, the incident angle of a front light sensor of the terminal is right opposite to the inner side of a vehicle roof, the external light sensitivity value of the vehicle cannot be detected, the rear light sensor incident angle of the terminal is right opposite to a vehicle instrument panel area, the external light sensitivity value of the vehicle cannot be detected, so that the light sensitivity value acquired by the light sensor of the terminal is much lower than the external ambient light intensity (i.e., the acquired ambient light error is larger), and the terminal backlight brightness of the ambient light based on the large error in the automatic backlight mode is lower, at this time, the terminal needs to maintain higher backlight brightness for navigation, and the current backlight brightness of a screen can be improved through secondary adjustment.

In this embodiment, the terminal enables the first light sensation parameter in the current environment to be acquired by controlling the contained front light sensation device to work; controlling the included rear light sensor to work, and enabling the second light sensor parameter in the current environment to be collected; and controlling the included top light sensor to work, so as to collect the third light sensing parameter in the current environment. The method comprises the following steps of accurately judging a corresponding daytime navigation scene needing backlight brightness adjustment in a second navigation mode based on a first light sensation parameter, a second light sensation parameter and a third light sensation parameter, and specifically comprises the following steps:

judging whether the third light sensation parameter acquired by the top light sensor is greater than the first light sensation parameter acquired by the front light sensor or not and whether the third light sensation parameter acquired by the top light sensor is greater than the second light sensation parameter acquired by the rear light sensor or not;

when the third light sensation parameter is greater than the first light sensation parameter and the third light sensation parameter is greater than the second light sensation parameter, the terminal is usually in a daytime navigation scene in which the backlight brightness needs to be adjusted in the second navigation mode, the terminal usually needs to keep high backlight brightness for navigation at the moment, and the backlight brightness of the screen is improved by the terminal through secondary adjustment.

In a possible implementation manner, the terminal may adjust the backlight brightness of the current screen according to a preset fixed value (which may be understood as a brightness adjustment value corresponding to the daytime navigation scene in the second navigation mode), such as increasing the backlight brightness of the current screen based on the preset fixed value.

In one possible embodiment, the terminal may obtain an eye parameter, such as an eyeball distance, between the terminal and the user in the current environment. And then determining a brightness adjustment value of the backlight brightness based on the eye parameter, and increasing the backlight brightness of the current screen according to the brightness adjustment value.

In addition, when the third light sensing parameter is less than or equal to the first light sensing parameter, and/or the third light sensing parameter is less than or equal to the second light sensing parameter, the backlight brightness of the current screen may not be adjusted.

Step S207: if the navigation mode is the second navigation mode, when the first light sensation parameter is smaller than a second light sensation threshold, the second light sensation parameter is smaller than a third light sensation threshold, and the third light sensation parameter is smaller than a fourth light sensation threshold, the backlight brightness of the screen is reduced.

In practical application, in a night navigation scene in a second navigation mode such as motor vehicle driving navigation, a terminal can be placed on a support (such as a vehicle-mounted support), due to the relation of the placement angle, the actual ambient light sensitivity value acquired by a light sensor is lower, and the lower backlight brightness is not beneficial to safe driving of a user (namely, the acquired ambient light error is larger), so that the backlight brightness of the terminal based on the ambient light with large error in the automatic backlight mode is lower, at the moment, the terminal needs to keep higher backlight brightness for navigation, and the current backlight brightness of a screen can be improved through secondary adjustment. And so on.

The second light sensation threshold is a threshold value or a critical value of the first light sensation parameter for judging the night navigation scene, the third light sensation threshold is a threshold value or a critical value of the second light sensation parameter for judging the night navigation scene, and the fourth light sensation threshold is a threshold value or a critical value of the third light sensation parameter for judging the night navigation scene.

In this embodiment, the second light sensation threshold, the third light sensation threshold, and the fourth light sensation threshold may be preset before the terminal leaves the factory, or may be changed by a user of the terminal on a corresponding setting interface in a later period of use.

In this embodiment, the terminal accurately determines a night navigation scene in the second navigation mode, which needs to adjust the backlight brightness, based on the first light sensation parameter, the second light sensation parameter, and the third light sensation parameter, specifically:

judging whether a first light sensation parameter acquired by a front light sensor is smaller than a second light sensation threshold value or not, whether a second light sensation parameter acquired by a rear light sensor is smaller than a third light sensation threshold value or not and whether a third light sensation parameter acquired by a top light sensor is smaller than a fourth light sensation threshold value or not;

when the first light sensation parameter is smaller than the second light sensation threshold, the second light sensation parameter is smaller than the third light sensation threshold, and the third light sensation parameter is smaller than the fourth light sensation threshold, the terminal is usually in a corresponding night navigation scene needing to adjust backlight brightness in the second navigation mode, the terminal usually needs to keep high backlight brightness for navigation, and the terminal improves the backlight brightness of the screen through secondary adjustment.

In a possible implementation manner, the terminal may adjust the backlight brightness of the current screen according to a preset fixed value (which may be understood as a brightness adjustment value corresponding to the night navigation scene in the second navigation mode), such as increasing the backlight brightness of the current screen based on the preset fixed value.

In addition, when the first light sensing parameter is greater than or equal to a second light sensing threshold, the second light sensing parameter is greater than or equal to a third light sensing threshold, and the third light sensing parameter is greater than or equal to a fourth light sensing threshold, the backlight brightness of the current screen may not be adjusted.

In the embodiment of the application, a terminal obtains backlight brightness of a screen in a current environment, then obtains a current navigation mode, controls at least one light sensor contained in the terminal to acquire light sensing parameters of the current environment based on the navigation mode, and adjusts the backlight brightness of the screen based on the navigation mode and the light sensing parameters. By acquiring the backlight brightness in the current environment and then taking the navigation mode and the light sensation parameters into the reference for the optimal adjustment of the backlight brightness of the screen based on the light sensation parameters acquired by the corresponding light sensation devices in the current navigation mode, on one hand, the light sensation devices can be intelligently controlled to acquire the light sensation parameters based on the actual scene requirements corresponding to the navigation mode in different navigation modes; on one hand, whether the terminal belongs to a special scene needing to optimize and adjust the backlight brightness in a certain navigation mode is determined based on the intelligently acquired light sensation parameters and in combination with the navigation mode, so that the terminal can optimize and adjust the backlight brightness of the screen in the scene, and for example, in corresponding scenes corresponding to the first navigation mode and the second navigation mode, the terminal can correspondingly increase or decrease the backlight brightness. The situation that the backlight brightness adjusting effect is poor under partial scenes due to the fact that backlight adjusting is carried out by the ambient light collected by the ambient light sensor in the related technology is avoided, the backlight optimizing effect of backlight adjusting is improved, and the accuracy of backlight adjusting is improved.

Referring to fig. 6, fig. 6 is a schematic flowchart illustrating another embodiment of a screen brightness adjusting method according to the present application. Specifically, the method comprises the following steps:

step S301: under the current environment, the backlight brightness of the screen is acquired.

Specifically, refer to step S101, which is not described herein again.

Step S302: and acquiring a current navigation mode, and controlling at least one light sensor contained in the navigation mode to acquire light sensing parameters of the current environment based on the navigation mode.

Specifically, refer to step S102, which is not described herein again.

Step S303: and monitoring the light sensation change rate of the light sensation parameters and the current motion data.

The light sensation change rate is used for representing the change degree of the light sensation parameter in unit time, and in this embodiment, whether the terminal has interference of a light interference source which appears suddenly at a certain moment or not can be judged according to the light sensation change rate. For example, in a night navigation scene, when a user of a terminal drives a vehicle to travel, a vehicle in front may be interfered by "vehicle light (light interference source)" in front due to a short travel distance, and at this time, a light sensation change rate may change abruptly.

The motion data and the data in the navigation motion process associated with the current terminal navigation state, such as motion speed, acceleration and motion distance; further, in the driving navigation scenario, the motion data may further include a separation distance (e.g., a separation distance from a vehicle in front), a relative speed (e.g., a relative speed with a vehicle in front), a motion time point (if there is a light interference source, the motion time point is an interference time point), and the like.

In this embodiment, the terminal may comprehensively determine whether there is interference from the light interference source in the navigation process by combining the light sensation change rate and the current motion data; further, when the interference of the light interference source exists, the light sensation value acquired by the terminal light sensor is much higher than the actual environment light outside the vehicle (namely the acquired environment light has larger error due to the light interference source), so that the terminal backlight brightness of the environment light with large error in the automatic backlight mode is inaccurate, if the terminal backlight brightness is too high, at the moment, the terminal can combine the light sensation change rate and the current motion data simultaneously, and the current backlight brightness of the screen can be adjusted through secondary adjustment. Such as turning down the current backlight brightness of the screen.

In some embodiments, the light sensation change rate of the light sensation parameter and/or the current motion data may be collected by a sensor device other than the terminal itself, that is, the terminal may be combined with an internet of things (e.g., an internet of vehicles) in an actual navigation scene, the terminal directly establishes a communication connection with a current navigation motion tool (e.g., a driving vehicle) through the internet of things, and then collects corresponding motion data based on the current navigation motion tool, for example, a radar velocimeter/range finder is used to detect a motion parameter, such as a relative distance, a relative speed, an interference time point, and the like, of a preceding vehicle, and, for example, a light sensor on the current navigation motion tool is used to detect the light sensation change rate of the light sensation parameter. Further, whether the terminal has interference of a suddenly appearing light interference source at a certain moment is judged based on the light sensation change rate and the motion data, and the backlight brightness of the screen is adjusted in a backlight mode under the condition that the interference exists.

Step S304: and determining an interference parameter corresponding to the light interference source based on the light sensation change rate and the motion data, and determining an adjustment factor based on the interference parameter.

The disturbance parameter comprises at least one of relative speed, disturbance time point, interval distance and light sensation change rate.

The disturbance parameter may be understood as a factor which disturbs the backlight adjustment determined on the basis of the motion data. In this embodiment, the disturbance parameter includes at least one of a relative speed, a disturbance time point, a separation distance, and a light sensation change rate.

In this embodiment, in an actual application environment, when the terminal is in a navigation scene and there is interference generated by a light interference source on backlight adjustment, usually multiple interference factors interfere with fitting, so that the backlight brightness of the terminal in the automatic backlight mode based on the environment light with large error is inaccurate, for example, is high. In the secondary adjustment process, the interference parameters corresponding to the light interference source are input to the backlight adjustment model based on the trained backlight adjustment model, and the adjustment factors corresponding to the interference parameters can be output. The adjustment factor is used for performing secondary adjustment on the current backlight brightness in the automatic backlight mode.

In a specific implementation manner, interference sample data in an actual navigation application environment is obtained in advance, feature information is extracted, a score corresponding to the interference sample data is labeled, the feature information includes at least one interference parameter (relative speed, interference time point, interval distance, light sensation change rate, and the like), and a backlight adjustment model is created. The backlight adjustment model may be trained by using a large amount of interference sample data, for example, the backlight adjustment model may be implemented based on at least one of a Convolutional Neural Network (CNN) model, a Deep Neural Network (DNN) model, a Recurrent Neural Network (RNN), a model, an embedding (embedding) model, a Gradient Boosting Decision Tree (GBDT) model, and a Logistic Regression (LR) model, and the backlight adjustment model may be trained based on the interference sample data to which the standard factor has been labeled, so that a trained backlight adjustment model may be obtained.

In the embodiment of the present application, the backlight adjusting model may create an initial model by using a hidden markov model (DNN-HMM model) introducing an error back propagation algorithm, and after extracting feature information of the interference sample data, input the feature information into the DNN-HMM model, a training process of the DNN-HMM model generally consists of two parts, namely, forward propagation and backward propagation, in the forward propagation process, a server inputs feature information corresponding to the sample-interference sample data, and transmits the feature information to an output layer after a transfer function (also referred to as an activation function and a conversion function) operation of hidden layer neurons (also referred to as nodes) from an input layer of the neural network model, wherein each layer of neuron states affects a next layer of neuron states, calculates an actual output value-abnormal information type at the output layer, calculates an expected error between the actual output value and an expected output value, and adjusting parameters of the DNN-HMM model based on the expected error, wherein the parameters comprise a weight value and a threshold value of each layer, and generating a backlight adjusting model after training.

Specifically, the desired error may be a mean square error MSE, which may be obtained by calculating a mean square error MSE between the actual output value and the desired output value, where the mean square error MSE may use the following formula:

wherein m is the number of output nodes, p is the number of training samples, is an expected output value, and is an actual output value.

In addition, a Markov Model (HMM) based convolutional neural network is created, the features of the interference sample data can be abstracted to a state sequence of the HMM, the interference features of the same state are different in each aspect due to the influence of external factors, the different interference features (such as a set of relative speed, interference time point, interval distance and light sensation change rate) can be regarded as the same set of state sequence, the different interference features correspond to the same HMM, and the occurrence and transition of the state can be described by using a probability matrix in the Model. For the same eye state, the corresponding HMM should be unique. The Hidden Markov Model is analyzed and established through the collected interference features, each interference factor in a group of interference features has certain correlation, interference vectors corresponding to the group of interference features also have relatively stable spatial structures in the process of vectorizing each interference factor, therefore, a plurality of states divided along the vertical direction can be respectively expanded to contain HMMs changing along the horizontal direction, the HMM in the vertical direction is called a main HMM, a plurality of groups of HMMs Embedded in the horizontal direction are called sub-HMMs, and the expanded one-dimensional HMM Embedded with state transition in the horizontal direction can be called an Embedded Hidden Markov Model (EHMM). A large amount of interference sample data is obtained in advance, then the interference characteristics extracted from the interference sample data are trained on the backlight adjustment model based on the interference sample data marked with the adjustment standard factors, and the trained backlight adjustment model can be obtained.

Step S305: backlight adjusting the backlight brightness of the screen based on the adjustment factor.

In one possible embodiment, the backlight adjustment process may be to add the current backlight brightness to the adjustment factor, and perform the backlight adjustment by taking the added sum as a target value of the backlight brightness adjustment.

In one possible embodiment, the backlight adjustment process may be to multiply the current backlight brightness by the adjustment factor, and perform the backlight adjustment by taking the multiplied product as the target value of the backlight brightness adjustment.

In the embodiment of the application, a terminal obtains backlight brightness of a screen in a current environment, then obtains a current navigation mode, controls at least one light sensor contained in the terminal to acquire light sensing parameters of the current environment based on the navigation mode, and adjusts the backlight brightness of the screen based on the navigation mode and the light sensing parameters. By acquiring the backlight brightness in the current environment and then taking the navigation mode and the light sensation parameters into the reference for the optimal adjustment of the backlight brightness of the screen based on the light sensation parameters acquired by the corresponding light sensation devices in the current navigation mode, on one hand, the light sensation devices can be intelligently controlled to acquire the light sensation parameters based on the actual scene requirements corresponding to the navigation mode in different navigation modes; on one hand, whether the terminal belongs to a special scene needing to optimally adjust the backlight brightness in a certain navigation mode is determined based on intelligently acquired light sensation parameters and in combination with the navigation mode, so that the terminal can optimally adjust the backlight brightness of the screen in the scene, the situation that the backlight brightness adjustment effect in partial scenes is poor due to the fact that the backlight adjustment is carried out depending on the ambient light acquired by an ambient light sensor in the related art is avoided, the backlight optimization effect of the backlight adjustment is improved, and the accuracy of the backlight adjustment is improved; on one hand, the backlight brightness can be adjusted according to the adjusting factor determined by the interference parameter under the condition of determining the interference parameter corresponding to the light interference source based on the light sensation change rate and the motion parameter, the adjusting mode is diversified, and the accurate adjustment of the backlight brightness is further realized.

In addition, the screen brightness adjusting device provided by the above embodiment and the screen brightness adjusting method embodiment belong to the same concept, and details of the implementation process are found in the method embodiment, and are not described herein again.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments.

An embodiment of the present application further provides a computer storage medium, where the computer storage medium may store a plurality of instructions, and the instructions are suitable for being loaded by a processor and executing the screen brightness adjustment method according to the embodiment shown in fig. 1 to 6, and a specific execution process may refer to specific descriptions of the embodiment shown in fig. 1 to 6, which is not described herein again.

The present application further provides a computer program product, where at least one instruction is stored in the computer program product, and the at least one instruction is loaded by the processor and executed by the method for adjusting screen brightness according to the embodiment shown in fig. 1 to 6, where a specific execution process may refer to specific descriptions of the embodiment shown in fig. 1 to 6, and is not described herein again.

Referring to fig. 11, a block diagram of an electronic device according to an exemplary embodiment of the present application is shown. The electronic device in the present application may comprise one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, memory 120, input device 130, and output device 140 may be connected by a bus 150.

Processor 110 may include one or more processing cores. The processor 110 connects various parts within the overall electronic device using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120 and calling data stored in the memory 120. Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), field-programmable gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a communication chip.

The Memory 120 may include a Random Access Memory (RAM) or a read-only Memory (ROM). Optionally, the memory 120 includes a non-transitory computer-readable medium. The memory 120 may be used to store instructions, programs, code sets, or instruction sets. The memory 120 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing various method embodiments described below, and the like, and the operating system may be an Android (Android) system, including a system based on Android system depth development, an IOS system developed by apple, including a system based on IOS system depth development, or other systems. The data storage area may also store data created by the electronic device during use, such as phone books, audio and video data, chat log data, and the like.

Referring to fig. 12, the memory 120 may be divided into an operating system space, where an operating system is run, and a user space, where native and third-party applications are run. In order to ensure that different third-party application programs can achieve a better operation effect, the operating system allocates corresponding system resources for the different third-party application programs. However, the requirements of different application scenarios in the same third-party application program on system resources are different, for example, in a local resource loading scenario, the third-party application program has a higher requirement on the disk reading speed; in the animation rendering scene, the third-party application program has a high requirement on the performance of the GPU. The operating system and the third-party application program are independent from each other, and the operating system cannot sense the current application scene of the third-party application program in time, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third-party application program.

In order to enable the operating system to distinguish a specific application scenario of the third-party application program, data communication between the third-party application program and the operating system needs to be opened, so that the operating system can acquire current scenario information of the third-party application program at any time, and further perform targeted system resource adaptation based on the current scenario.

Taking an operating system as an Android system as an example, programs and data stored in the memory 120 are as shown in fig. 13, and a Linux kernel layer 320, a system runtime library layer 340, an application framework layer 360, and an application layer 380 may be stored in the memory 120, where the Linux kernel layer 320, the system runtime library layer 340, and the application framework layer 360 belong to an operating system space, and the application layer 380 belongs to a user space. The Linux kernel layer 320 provides underlying drivers for various hardware of the electronic device, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 340 provides a main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system runtime library layer 340 is an Android runtime library (Android runtime), which mainly provides some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 360 provides various APIs that may be used in building an application, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, session management, resource management, and location management. At least one application program runs in the application layer 380, and the application programs may be native application programs carried by the operating system, such as a contact program, a short message program, a clock program, a camera application, and the like; or a third-party application developed by a third-party developer, such as a game application, an instant messaging program, a photo beautification program, a screen brightness adjustment program, and the like.

The kernel operating system layer 420 includes an operating system kernel, drivers, and underlying program frameworks that provide functionality closer to hardware for use by program frameworks located in the core services layer 440. The core services layer 440 provides system services and/or program frameworks, such as a Foundation framework, an account framework, an advertisement framework, a data storage framework, a network connection framework, a geographic location framework, a motion framework, and so forth, as required by the application. The media layer 460 provides audiovisual related interfaces for applications, such as graphics image related interfaces, audio technology related interfaces, video technology related interfaces, audio video transmission technology wireless playback (AirPlay) interfaces, and the like. Touchable layer 480 provides various common interface-related frameworks for application development, and touchable layer 480 is responsible for user touch interaction operations on the electronic device. Such as a local notification service, a remote push service, an advertising framework, a game tool framework, a messaging User Interface (UI) framework, a User Interface UIKit framework, a map framework, and so forth.

In the framework illustrated in FIG. 14, the framework associated with most applications includes, but is not limited to: a base framework in the core services layer 440 and a UIKit framework in the touchable layer 480. The base framework provides many basic object classes and data types, provides the most basic system services for all applications, and is UI independent. While the class provided by the UIKit framework is a basic library of UI classes for creating touch-based user interfaces, iOS applications can provide UIs based on the UIKit framework, so it provides an infrastructure for applications for building user interfaces, drawing, processing and user interaction events, responding to gestures, and the like.
