The embodiments of the present disclosure will be described below with reference to practical applications.
In the embodiment of the present disclosure, an implementation process of adjusting the screen brightness of the terminal to match the screen brightness of the current light sensing data of the preset usage scene according to the current light sensing data of the preset usage scene is first described.
In the embodiment of the present disclosure, a model training method may be adopted for the preset usage scenes to obtain the screen brightness adjustment curve of each preset usage scene through pre-training. And the screen brightness adjusting curve is used for adjusting the corresponding relation between the standard screen brightness and the light sensing data. In an embodiment, when the screen brightness is adjusted for a preset usage scene, the adjustment may be performed according to a corresponding relationship between the screen brightness and the light sensing data in the screen brightness adjustment curve. For example, the acquired current light sensing data is compared with a screen brightness adjusting curve, the screen brightness matched with the current light sensing data can be determined, and then the screen brightness of the terminal is adjusted according to the matched screen brightness to be the screen brightness matched with the current light sensing data, so that the adjusted terminal screen brightness is suitable for users to use. The screen brightness is adjusted through the preset screen brightness adjusting curve, so that the accurate screen brightness is provided for a user when a preset use scene is used, and the backlight effect of a terminal screen is improved.
The screen brightness and the light sensing data range have a corresponding relationship. The current light sensing data of the preset use scene is compared with the light sensing data corresponding to the screen brightness requirement of the preset use scene, and the screen brightness corresponding to the current light sensing data can be determined. According to the current light sensing data, the screen brightness of the terminal is adjusted, the adjusted screen brightness can be matched with the current light sensing data of the current use scene, the terminal screen can provide proper backlight brightness for the current use scene, and therefore the use experience of a user is improved.
In the embodiment of the disclosure, in order to avoid the jitter of the light sensing data and the instability of the screen brightness caused by the frequent change of the external light, the corresponding relationship between the screen brightness and the light sensing data range is set, and the screen brightness is adjusted according to the light sensing data range.
In order to enable the screen brightness of the terminal to be more stable and reduce discomfort of a user caused by the screen brightness when the user uses a preset use scene due to light sensing data jitter, another screen brightness adjusting method is further provided in the disclosure.
Fig. 2 is a flowchart illustrating another screen brightness adjustment method according to an exemplary embodiment, and as shown in fig. 2, the screen brightness adjustment method is used in a terminal and includes the following steps S21 to S24.
In the present disclosure, the implementation of step S21 and step S22 are the same as the implementation of step S11 to step S12, respectively, and are not described again here.
In step S21, the usage scenario of the terminal is identified as a preset usage scenario.
In step S22, the screen brightness of the terminal is adjusted to match the screen brightness of the current light sensing data of the preset usage scene according to the current light sensing data of the preset usage scene.
In step S23, the current light sensing data is monitored for a preset monitoring period, and the variation range of the light sensing data for the monitoring period is determined.
In the disclosed embodiment, different screen brightnesses have corresponding light sensing data ranges. In order to keep the stability of the adjusted screen brightness, the current light sensing data is continuously acquired in a preset monitoring period. And analyzing the light sensing data acquired in the monitoring period, and determining the change range of the light sensing data in the monitoring period so as to judge whether the light outside the terminal changes. According to the light sensing data change range, the screen brightness of the terminal in the current preset use scene is adjusted, the adjusted screen brightness is matched with the current light sensing data, and therefore the adjusted screen brightness is more suitable for users to use, and therefore the use experience of the users is improved.
In step S24, the screen brightness of the terminal is readjusted according to the light sensing data variation range in the monitoring period and the light sensing data range corresponding to the current screen brightness of the terminal.
In the embodiment of the disclosure, according to the change range of the light sensing data in the monitoring period, it is helpful to determine whether the light outside the terminal changes significantly or only the obtained light sensing data shakes slightly. Through the change of periodically observing light sensing data, the screen brightness of the terminal is readjusted by combining the light sensing data range corresponding to the current screen brightness of the terminal, so that the phenomenon of shaking during screen brightness adjustment is reduced, the screen brightness is flickering, and user experience is influenced.
In an embodiment, if the light sensing data variation range in the monitoring period belongs to the light sensing data range corresponding to the current screen brightness of the terminal, the screen brightness of the terminal is kept unchanged. For example: in the monitoring period, the light sensing data has no obvious fluctuation change or individual abnormal light sensing data, but the whole light sensing data change range belongs to the light sensing data range corresponding to the current screen brightness of the terminal, and the current screen brightness is maintained. For example: and when the light sensing data suddenly rises or falls and lasts for a period of time, but all the light sensing data belong to the light sensing data range corresponding to the current screen brightness, the screen brightness of the terminal is kept unchanged.
In another embodiment, if the light sensing data change range in the monitoring period does not belong to the light sensing data range corresponding to the current screen brightness of the terminal when the light sensing data change, the screen brightness is adjusted, so that the light sensing data change range in the monitoring period belongs to the light sensing data range corresponding to the adjusted screen brightness, and the use by a user is facilitated. For example: and if the light sensing data in the light sensing data change range in the monitoring period is higher than the light sensing data in the light sensing data range corresponding to the current screen brightness of the terminal screen, reducing the screen brightness of the terminal, so that the light sensing data change range in the monitoring period belongs to the light sensing data range corresponding to the adjusted screen brightness. And if the light sensing data in the light sensing data change range in the monitoring period is lower than the light sensing data in the light sensing data range corresponding to the current screen brightness of the terminal screen, the screen brightness of the terminal is improved, and the light sensing data change range in the monitoring period belongs to the light sensing data range corresponding to the adjusted screen brightness. Therefore, the use requirements of the user are met, and the use experience of the user is improved.
The embodiment of the present disclosure will describe an implementation process for identifying whether a terminal usage scenario is a preset usage scenario.
In an embodiment, the usage scenario of the terminal may be identified as a preset usage scenario according to one or a combination of current geographic location information of the terminal, current motion state information of the terminal, currently running application information of the terminal, and the like.
In an example, the embodiment of the present disclosure may acquire current geographic position information of the terminal through a Global Positioning System (GPS), and determine whether an environmental scene where the terminal is currently located is a preset environmental scene according to the current geographic position information. It is assumed that the preset environmental scene includes an indoor environment and an outdoor environment. And the current geographic position is acquired by the GPS and is a cinema, so that the environment scene can be determined to be a preset indoor environment scene. The current geographic position is acquired through the GPS and is an outdoor place such as a park, and the environment scene where the current geographic position is located can be determined to be a preset outdoor environment scene.
In another example, the current motion state information of the terminal is obtained through an acceleration sensor, and whether the current motion state scene of the terminal is a preset motion state scene is determined according to the current motion state information. For example, the preset motion state scenario includes: a walking scene, a running scene, a vehicle-mounted moving scene, and the like.
The current motion state information of the terminal is obtained through an acceleration sensor or the acceleration sensor and a gyroscope sensor, and then the motion state scene where the terminal is located at present is determined to be a preset motion state scene. And when the current motion state scene of the terminal is determined to be the preset motion state scene according to the current motion state information, providing proper screen brightness for the user, and facilitating the use of the user.
In another example, whether the application currently running on the terminal is a preset application scene can be determined according to the application type currently running on the terminal. For example, the preset application scene may be a camera, a game, a social chat, and the like. And identifying the application scene currently operated by the terminal, and further providing proper screen brightness according to the preset application scene, so that the terminal is convenient for a user to use.
When the screen brightness is adjusted, the brightness is adjusted according to current light sensing data obtained by the light sensor of the terminal acquiring outside light. In the related art, the external light is obtained through a front light sensor of the terminal. However, the front light sensor is easily shielded. When the front light sensor is shielded, the light sensing data acquired by the light sensor easily shakes, the current external light environment cannot be accurately identified, accurate screen brightness cannot be provided when the screen brightness is adjusted, the backlight effect is unsatisfactory, and the use experience of a user is influenced.
The screen brightness convenient to adjust is more stable, and the problem that the screen brightness brings discomfort to a user when the user uses a preset use scene due to the fact that the light sensing data shake is reduced.
In the present disclosure, light sensors are disposed on both the front and rear sides of the terminal. As shown in fig. 3, a front light sensor is disposed in the direction of the terminal screen. As shown in fig. 4, a rear light sensor is arranged on the back of the terminal screen. The front light sensor is mainly used for acquiring light sensing data on the front side of a terminal screen. The rear light sensor is mainly used for acquiring light sensing data on the back face of the terminal, can be located at any position of the back face of the terminal, and can be arranged below the flash lamp for the convenience of attractiveness of the appearance of the terminal. For convenience of description, the light sensing data acquired by the front light sensor in a preset usage scenario is referred to as first light sensing data. The light sensing data acquired by the rear light sensor in the preset usage scene is referred to as second light sensing data. Through leading optical line sensors and rearmounted optical line sensors, acquire terminal screen external light environment under presetting the use scene, help the terminal more comprehensive acquire the terminal external light sensing data, and then provide stable screen brightness, the user of being convenient for uses.
In the embodiment of the present disclosure, the first light sensing data and the second light sensing data may be combined in a combination manner such as weighting or averaging, so as to finally determine the light sensing data of the terminal.
In the embodiment of the disclosure, light sensing data are acquired through the front light sensor and the rear light sensor respectively, so that when the front light sensor is sheltered, the acquired first light sensing data are unstable, the light sensing data acquired from the terminal are subject to error, and the stability of the screen brightness is affected. For example: when the terminal is used for playing games, the front light sensor is often shielded by fingers of a user, so that the first light sensing data acquired by the front light sensor can shake, and the light sensing data for adjusting the screen brightness is unstable. However, the rear light sensor cannot be easily shielded, and therefore the second light sensing data acquired by the rear light sensor is stable, and the first light sensing data and the second light sensing data are acquired simultaneously, so that the external light sensing data of the current terminal can be determined, and the adjustment of the screen brightness is more stable.
In an embodiment, the first light sensing data and the second light sensing data are combined in a weighted manner according to the assigned weight, so as to obtain the light sensing data of the terminal. Because the first light sensing data and the second light sensing data both have accuracy, weighting processing is performed through the assigned weight, data errors are reduced, and the light sensing data acquired by the terminal is more accurate.
In an embodiment, the assigned weights include a first weight and a second weight. In the embodiment of the present disclosure, a weight value of the first weight is set to be greater than a weight value of the second weight. When the light sensing data of the terminal is determined by combining the first light sensing data and the second light sensing data, the acquired first light sensing data is compared with the acquired second light sensing data, the light sensing data with the larger data value is weighted by using the first weight, and the light sensing data with the smaller data value is weighted by using the second weight.
In the embodiment of the disclosure, the first weight is assigned to the light sensing data with a higher data value in the first light sensing data and the second light sensing data, so that the accuracy of the light sensing data acquired by the terminal is not affected by backlight or backlight of an external light source, and the screen brightness of the terminal is stabilized conveniently.
In one implementation scenario, assume that the first weight is 0.7 and the second weight is 0.3. When the terminal is used in a backlight, for example, when a user sits under a desk lamp and uses the terminal in a bed, the first light sensing data is 500 lux, and the second light sensing data is 300 lux, then the light sensing data of the terminal is 470 lux after the weighting processing, that is, the 500 lux is multiplied by 0.7 and the 400 lux is multiplied by 0.3. When the user lies on the terminal, the acquired first light sensing data is 300 lux, the acquired second light sensing data is 500 lux, and the light sensing data of the terminal is 470 lux after weighting processing, wherein the 500 lux is multiplied by 0.7 and the 400 lux is multiplied by 0.3, and the light sensing data is the same as the light sensing data of the backlight acquisition terminal, so that the screen brightness cannot be changed, and the stability of the screen brightness is convenient to maintain.
In another embodiment, fixed weights are set for the front light sensor and the rear light sensor, such as: the first weight is the weight of the front light sensor for acquiring the first light sensing data, and the second weight is the weight of the rear light sensor for acquiring the second light sensing data. The fixed weight of the light sensor is set in a determined mode, so that the accuracy of the light sensing data of the terminal is improved under the condition that the light source is stable, the stability of the screen brightness is kept for a long time, and the use experience of a user is improved.
In the embodiment of the disclosure, after the use scene of the terminal is identified, the light sensing data of the current use scene of the terminal is determined by using the light sensing data respectively collected by the front light sensor and the rear light sensor, so that the accuracy of determining the identified use scene of the terminal can be further improved. For example: and positioning the current geographic position as the home of the user according to the GPS, and acquiring the current motion state as static through the accelerometer sensor, so that the current use scene of the terminal can be determined as indoor game playing. The current indoor light source can be determined to be a point light source according to the front sensor and the rear sensor, and then the current use scene can be determined to be a desk lamp scene, so that the screen brightness of softer light brightness needs to be matched.
By applying the embodiment of the disclosure, the screen brightness of the terminal can be simply and easily adjusted to match the screen brightness of the preset use scene aiming at the preset use scene. As shown in fig. 5, when the front light sensor and the rear light sensor are used to acquire light sensing data, the GPS is used to acquire geographical position information, and the acceleration sensor is used to acquire operation state information of the terminal (whether the terminal is mounted on a vehicle or is walking), the usage scene of the terminal is identified. And if the identified use scene is the preset use scene. For example, the usage scene of the terminal is recognized as one or more scenes of a camera shooting scene, a walking scene, a table lamp scene, an indoor scene, a game scene, a lying scene and the like. According to the screen brightness adjusting requirement corresponding to the preset use scene, the screen brightness can be directly adjusted to be matched with the screen brightness of the current use scene.
In the embodiment of the disclosure, when the use scene of the terminal is identified as the preset use scene, the screen brightness of the terminal is adjusted to match the screen brightness of the current light sensing data of the preset use scene according to the current light sensing data of the preset use scene, so that the terminal screen can provide more appropriate backlight brightness for the current use scene, and the use experience of a user is improved.
