The embodiment of the disclosure provides a screen brightness adjusting method, which includes the steps that light sensors arranged in front and at back of a terminal are used for obtaining light sensing data around the outside of the terminal, and then the brightness of a screen of the terminal is adjusted according to the light sensing data, so that the terminal can provide stable screen brightness when in use, discomfort brought to user experience by screen brightness jitter is avoided, and the user experience is enhanced.
It can be understood that the terminal involved in the embodiments of the present disclosure may include: cell phones, tablets, notebooks, etc., and are not limited in this disclosure.
Fig. 1 is a flowchart illustrating a screen brightness adjusting method according to an exemplary embodiment, where the screen brightness adjusting method is used in a terminal, as shown in fig. 1, and includes the following steps S11 to S13.
In step S11, first light sensing data collected by the front light sensor is acquired, and second light sensing data collected by the rear light sensor is acquired.
In the embodiment of the disclosure, the light sensors are arranged on the front side and the rear side of the terminal. A front light sensor is arranged in the direction of the terminal screen, and 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 of the terminal.
For convenience of description, the light sensing data acquired by the front light sensor is referred to as first light sensing data. The light sensing data acquired by the rear light sensor is referred to as second light sensing data.
In the embodiment of the disclosure, the external light environment of the screen of the terminal is acquired through the front light sensor and the rear light sensor, so that the terminal can acquire the external light sensing data of the terminal more comprehensively, and further stable screen brightness is provided, and the user can use the terminal conveniently.
In step S12, light sensing data of the terminal is determined based on the first light sensing data and the second light sensing data.
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 step S13, the screen brightness of the terminal is adjusted according to the light sensing data.
In the embodiment of the disclosure, different terminal use scenes have different screen brightness parameters, and the different screen brightness parameters correspond to different light sensing data ranges. For example: when the mobile phone is in a use scene such as a game or a video, the screen needs to be high-bright. When the mobile phone is used under a night desk lamp, the mobile phone needs soft screen brightness. According to the acquired light sensing data, the light sensing data range to which the acquired light sensing data belong is determined, and then the screen brightness of the terminal is adjusted, so that the screen brightness suitable for the user is provided. When the light sensing data are abnormally floated, the influence of jitter on the brightness of a terminal screen is reduced. The application scenario may include: camera, game, social chat, etc., and are not limited in this disclosure.
In an embodiment, in order to maintain the stability of the screen brightness parameter, the light sensing data in the specified monitoring period is acquired, the light sensing data acquired in the specified period is analyzed through a preset analysis model, the change trend of the light sensing data in the period is determined, whether the light around the terminal changes obviously or not is judged, and then the current screen brightness of the terminal is adjusted according to the change trend, so that the adjustment of the screen brightness is more reasonable and more suitable for users to use, and the use experience of the users is improved.
In another embodiment, according to the variation trend of the light sensing data in the designated monitoring period, if the light sensing data has no obvious fluctuation change or has individual abnormal light sensing data and is in the light sensing data range corresponding to the current screen brightness of the terminal screen, the current screen brightness is maintained. When the light sensing data changes, for example, 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 also kept unchanged. If the change trend of the light sensing data is obviously increased and is higher than the light sensing data range corresponding to the current screen brightness of the terminal screen, the brightness of the screen is reduced, so that the screen brightness is more suitable for the current light, and the use by a user is facilitated. If the change trend of the light sensing data is obviously reduced and is lower than the light sensing data range corresponding to the current screen brightness of the terminal screen, the brightness of the screen is improved, the use requirement of a user is met, and the use experience of the user is improved.
Through above-mentioned embodiment, utilize leading optical line sensors and the rear optical line sensors at terminal to acquire the light sensing data of both sides around the terminal, the light condition at present terminal can be acquireed to more accurate, makes the adjustting of the lighteness of terminal screen more stable, is favorable to promoting user's use and experiences.
Fig. 2 is a flow chart illustrating another brightness adjustment according to an exemplary embodiment, which makes the screen brightness of the terminal more stable and more accurate by combining the scene where the terminal is located. The scene may include: the present disclosure is not limited to walking, indoor, lying, and other scenes.
As shown in fig. 2, the screen brightness adjusting method is used in a terminal, and includes the following steps S21 to S24.
In the present disclosure, the implementation of step S21, step S22 and step S24 are the same as the implementation of step S11 to step S13, respectively, and are not described again.
In step S21, first light sensing data collected by the front light sensor is acquired, and second light sensing data collected by the rear light sensor is acquired.
In step S22, light sensing data of the terminal is determined based on the first light sensing data and the second light sensing data.
In step S23, the scene where the terminal is currently located is determined, and the screen brightness of the terminal is adjusted to match the brightness of the scene where the terminal is currently located.
In the embodiment of the disclosure, according to the acquired light sensing data, the brightness of the current screen is adjusted by combining with the determination of the scene where the current terminal is located, so that the terminal screen is more suitable for the current use state of a user when being used, and further, the display effect of screen backlight is improved, and the use experience of the user is improved.
In one embodiment, the current geographic location of the terminal is determined by obtaining current geographic location information of the terminal through a Global Positioning System (GPS), for example: in the cinema or outdoor places such as parks, the screen brightness is conveniently improved or reduced according to the current environment, the appropriate screen brightness is provided, and the use by users is convenient. Or the current motion state information of the terminal is acquired through the acceleration sensor or by combining with the gyroscope sensor, so that the motion state of the user is judged, and the appropriate screen brightness is provided for the user according to the current motion state information, so that the user can use the device conveniently. The motion state may include: walking, running, carrying vehicles for movement, and the like.
In another embodiment, the sensing data of the GPS and the accelerometer sensor are acquired simultaneously, and the screen brightness is adjusted together by combining the light transmission data of the terminal, so that the backlight effect of the screen brightness is optimized, and the adjusted screen brightness is more suitable for users. For example: according to the application scene of the current game, the screen brightness is improved by combining the current light sensing data. The method comprises the steps of positioning a home of a user according to a GPS, obtaining a current motion state as static through an accelerometer sensor, obtaining a scene that the current state of the user is lying according to a fixed relation between an accelerometer sensor coordinate system and a terminal position coordinate system, reducing a brightness value for improving screen brightness, improving comfort of the user, and improving use experience of the user.
In step S24, the screen brightness of the terminal is adjusted according to the light sensing data.
Based on the same inventive concept, the embodiment of the disclosure also provides a screen brightness adjusting device.
