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.
With the development of mobile terminal equipment technology, at present, the popularization rate of mobile terminal equipment such as mobile phones is higher and higher, smart phones become essential personal articles for people to go out, in order to realize good user experience, many smart phones support automatic backlight brightness adjustment, and backlight brightness is automatically driven and adjusted through different ambient light intensities.
At present, mobile terminal devices such as mobile phones and the like can intelligently adjust a backlight brightness value of a screen of the terminal device through an ambient light sensor, for example, when an ambient light intensity value detected by the ambient light sensor is small, the terminal device can set the backlight brightness value of the screen to a low value, and when the ambient light intensity value detected by the ambient light sensor is large, the terminal device can set the backlight brightness value of the screen to a high value, so that the purposes of improving visual experience of users, reducing power consumption of electronic terminals, prolonging battery working time of the terminal device to the maximum extent and the like are achieved.
However, the inventor of the present invention has found in research that, in a terminal device such as a mobile phone, two sets of backlight lamps are usually arranged in a backlight module (the number of the backlight lamps is related to the screen size of the terminal device), and when the backlight brightness is adjusted according to the ambient light intensity around the terminal device, the brightness of all the backlight lamps is adjusted according to the ambient light intensity, which results in that the existing automatic backlight adjustment cannot completely meet the requirements of users in various use scenes. For example, when a user uses the terminal device to be located in a burning sun, even if the backlight brightness is automatically adjusted to the maximum value, the user still has difficulty in seeing the content displayed on the screen of the terminal device clearly due to too strong sunlight and can only avoid the user to operate in a shady and cool place; for another example, when the user uses the terminal device in the dark, the existing terminal device automatically adjusts the backlight brightness to the minimum, and since all the backlights are turned on, the user may still feel dazzling of the screen but cannot adjust the backlight brightness to a lower level.
In order to solve the above problems, the inventors have studied and proposed a backlight adjustment method, a backlight adjustment apparatus, a terminal device, and a computer-readable storage medium in the embodiments of the present application.
The backlight adjusting method, the backlight adjusting apparatus, the terminal device and the storage medium provided by the embodiments of the present application will be described in detail through specific embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a backlight adjusting method according to an embodiment of the present application. The backlight adjusting method comprises the steps of firstly detecting the current ambient light intensity when an application processor is awakened, then determining a backlight intensity threshold interval corresponding to the current ambient light intensity, then generating a backlight switching instruction according to the backlight intensity threshold interval, wherein the backlight switching instruction is used for switching the number of backlights corresponding to the backlight intensity threshold interval in a backlight module to be turned on, and finally carrying out brightness adjustment on the backlights in the turned-on state according to the current ambient light intensity. In a specific embodiment, the backlight adjusting method may be applied to the backlight adjusting apparatus 300 shown in fig. 5 and the terminal device 100 shown in fig. 6, and the backlight adjusting method is used to improve the experience of the user in viewing the display using the terminal device. The flow shown in fig. 1 will be described in detail below. The backlight adjusting method described above may specifically include the steps of:
step S101: when the application processor wakes up, the current ambient light intensity is detected.
The backlight adjusting method provided by the embodiment can be suitable for terminal equipment, and the terminal equipment can be portable terminal equipment such as a mobile phone, a tablet personal computer and a wearable intelligent terminal. An Application Processor (AP) is disposed in the terminal device and is responsible for processing applications, such as games and web pages, running in the terminal device system.
When the application processor wakes up, the terminal device may be considered to be currently about to light up the screen for displaying, and at this time, the backlight brightness required by the screen display needs to be adjusted. Before adjusting the backlight brightness, the current ambient light intensity of the current environment where the terminal device is located may be detected by the ambient light detection module.
As a mode, the ambient light detection module can detect the light intensity of the environment where the terminal device is located in real time in the screen-off and screen-on states; the light intensity of the environment in which the terminal device is located may be detected only in the wake-up state of the application processor.
Step S102: and determining a backlight intensity threshold interval corresponding to the current ambient light intensity.
In this embodiment, as a way, each backlight intensity threshold interval corresponds to the number of backlight lamps turned on, and the same backlight intensity threshold interval may correspond to a plurality of ambient light intensities. For example, when the ambient light intensity is greater than 0 and less than or equal to a, the ambient light intensity corresponds to a backlight intensity threshold interval a, and the backlight intensity threshold interval a corresponds to turning on 1 group of backlight lamps; when the intensity of the ambient light is greater than a and less than or equal to B, corresponding to a backlight intensity threshold interval B, wherein the backlight intensity threshold interval B corresponds to 2 groups of backlight lamps which are turned on; when the intensity of the ambient light is greater than b and less than or equal to C, the intensity of the ambient light corresponds to a backlight intensity threshold interval C, and the backlight intensity threshold interval C corresponds to the opening of 3 groups of backlight lamps; and so on.
Step S103: and generating a backlight lamp switching instruction according to the backlight intensity threshold interval.
In this embodiment, the backlight lamp switching instruction may be used to switch the number of backlight lamps corresponding to the backlight intensity threshold interval in the backlight module to an on state.
As one mode, the backlight module of the terminal device includes a backlight lamp switching circuit and a plurality of sets of backlight lamps. The control module of the terminal device can determine a backlight intensity threshold interval matched with the current ambient light intensity according to the current ambient light intensity reported by the ambient light detection module, and then generate a corresponding backlight switching instruction according to the determined backlight intensity threshold interval, wherein the backlight switching instruction can be used for controlling the backlight switching circuit to switch the backlight which needs to be turned on.
Step S104: and adjusting the brightness of the backlight lamp in the open state according to the current ambient light intensity.
In this embodiment, after the backlight lamps corresponding to the switching number and the current ambient light intensity are turned on, an automatic backlight brightness adjustment algorithm may be further activated according to the current ambient light intensity to adjust the brightness of the backlight lamps in the turned-on state.
As a mode, the brightness of the backlight after brightness adjustment has a corresponding relationship with the current ambient light intensity, and when the ambient light intensity is higher, the total backlight brightness value provided by each group of backlights is higher; the total backlight brightness value provided by each set of backlights is smaller when the ambient light intensity is smaller.
In some possible implementation scenarios, for example, when the ambient light intensity around the terminal device gradually increases (for example, when the terminal device moves outdoors along an indoor corridor, the ambient light irradiated to the terminal device may gradually increase), the backlight intensity threshold interval corresponding to the backlight intensity threshold interval may gradually change from the backlight intensity threshold interval corresponding to 1 group of backlights to the backlight intensity threshold interval corresponding to 2 groups of backlights, and when the brightness of the first group of backlights increases to the maximum value, the backlight switching circuit rapidly switches the backlights to 2 groups, and at this time, because the second group of backlights also provides backlight brightness for the entire display screen, as a way, the backlight brightness of the first group of backlights may decrease, and as the ambient light intensity increases, the brightness of the two groups of backlights is adjusted to gradually increase; alternatively, the brightness of the first group of backlights may be kept constant after being raised to the maximum value, and only the brightness of the second group of backlights may be adjusted to gradually increase as the intensity of the ambient light increases.
It is understood that the brightness adjustment manner and logic of each group of back light lamps in the on state may be arbitrary, and only the total back light brightness of all the turned-on back light lamps is increased along with the increase of the ambient light intensity. In some embodiments, the adjustment of the brightness of the backlight may also introduce other characteristic parameters, which are used as criteria for brightness adjustment simultaneously with the current ambient light intensity, to further optimize the accuracy of brightness adjustment.
According to the backlight adjusting method provided by one embodiment of the application, when the application processor of the terminal device is awakened, the number of the backlight lamps needing to be started can be determined according to the current ambient light intensity, and after the number of the terminal device backlight lamps to be started is switched, the brightness of the backlight lamps in the starting state can be adjusted according to the ambient light intensity, so that the adjustable range of the backlight is expanded, more accurate automatic backlight brightness adjustment is realized, and the experience of a user watching the screen of the terminal device is improved.
Referring to fig. 2, fig. 2 is a flow chart illustrating a backlight adjusting method according to another embodiment of the present application. The flow shown in fig. 2 will be described in detail below. The backlight adjusting method described above may specifically include the steps of:
step S201: when the application processor wakes up, the current ambient light intensity is detected.
Step S202: and acquiring the application program information of the current foreground application operated by the current foreground.
In this embodiment, the current foreground application may be an application program currently running in the system foreground of the terminal device, and the current foreground application may display a corresponding image or interface on a human-computer interaction interface (such as a touch display screen) of the terminal device, so as to be viewed or operated by a user.
The application information may include various feature information of the current foreground application, such as an application name, an application type, an application size, and the like, which may be used to represent a current running state of the current foreground application.
Step S203: and determining a backlight intensity threshold interval corresponding to the current ambient light intensity and the application program information according to the current ambient light intensity and the application program information.
In this embodiment, different application programs may correspond to different most suitable backlight intensities, and as one mode, the application program information of each application program may be associated with the most suitable backlight intensity and used as a characteristic parameter to influence the corresponding relationship between the current ambient light intensity and the backlight intensity threshold interval. It is understood that different applications, under the same ambient light intensity, may correspond to different backlight intensity threshold intervals; the application information of the same application in different operating states may also correspond to different backlight intensity threshold intervals.
Step S204: and generating a backlight lamp switching instruction according to the backlight intensity threshold interval.
In this embodiment, the backlight lamp switching instruction is used to switch the number of backlight lamps corresponding to the backlight intensity threshold interval in the backlight module to on.
In some embodiments, the application information may include application scene information including a base brightness value and a brightness position distribution of at least one scene displayed during the running of the current foreground application.
For example, when the foreground application is a video playing application, it can play video images with multiple scenes, such as a bright daytime scene, a warm dusk scene, and a dark night scene, etc., in different scenes, the image brightness values of the video images are different, for example, the image brightness value in the daytime scene is significantly higher than the image brightness value in the night scene, and the image brightness value can be used as the reference brightness value of the corresponding scene.
For example, in a dusk scene, the brightness of the sky is significantly greater than the brightness of the ground backlight, and if the sky is located at the upper right of the image and the ground backlight is located at the lower left of the image, the brightness position distribution of the scene (or the image or the picture) is high at the upper right and low at the lower left.
Step S205: and determining the brightness position distribution of the current scene according to the application scene information.
In this embodiment, the luminance position distribution of the currently displayed image scene may be obtained in real time according to the application scene information of the current foreground application.
Step S206: based on the brightness position distribution of the current scene, backlight lamp position information corresponding to the current scene is acquired.
In this embodiment, after the luminance position distribution of the current scene is acquired, the position information such as the backlight corresponding to the luminance position distribution can be acquired. As one way, the backlight position information is associated with the position of the backlight currently on in the backlight module.
Step S207: a backlight position switching instruction is generated based on the backlight position information.
In this embodiment, the backlight position switching instruction may be used to control the backlight switching circuit to switch the backlight lamps in the backlight module, the number of which corresponds to the backlight intensity threshold interval and the position of which corresponds to the backlight position information, to the on state.
For example, under the condition that the intensity of ambient light is not changed, the brightness position distribution of the previous scene is high in middle brightness and low in surrounding brightness, when the previous scene is displayed, the backlight lamps located at the corresponding positions in the middle of the display screen of the terminal device are turned off, and the backlight lamps located at the corresponding positions in the surrounding of the display screen are turned on; when the previous scene is switched to the current scene for display, the brightness position distribution of the current scene is high at the upper right and low at the lower left, and the backlight at the position corresponding to the brightness position distribution needs to be turned on, at this time, the backlight at the position corresponding to the middle upper right around the display screen can be turned off, and the backlight at the position corresponding to the middle lower left around the display screen can be turned on.
As a way, in a position with lower brightness in the brightness position distribution of the current scene, a backlight lamp may be turned on to reinforce the brightness of the display picture corresponding to the position; the backlight can also be turned off to enhance the contrast of the whole picture. It can be understood that, according to different preferences of users, backlight position information corresponding to the same brightness position distribution may be different, and the backlight position information may be configured in a user-defined manner according to the preferences of users, or may be automatically optimized according to the usage habits of users.
In some possible embodiments, in order to adjust the backlight brightness more accurately according to the scene brightness position distribution under the condition that the ambient light intensity is not changed, the number of backlights corresponding to different backlight position information may also be different, that is, when the ambient light intensity is not changed, the scene backlight brightness position distribution may affect the number, position, and brightness of the backlights which are finally turned on.
In this embodiment, after the backlight corresponding to the current ambient light intensity and the current scene is turned on, the brightness of the backlight in the turned-on state may be adjusted according to the current ambient light intensity, and specifically, step S208 and step S209 may be performed.
Step S208: and determining a reference brightness value of the current scene according to the application scene information.
Step S209: and adjusting the brightness of the backlight lamp in the starting state according to the current ambient light intensity and the reference brightness value of the current scene.
In this embodiment, as a manner, the reference brightness value of the current scene may be used as a feature parameter to associate the brightness value finally adjusted by the backlight in the on state.
In some embodiments, similar to the above-mentioned brightness position distribution, when the ambient light intensity and the brightness position distribution are substantially unchanged, the finally adjusted backlight brightness value corresponding to the same reference brightness value may be different, and may be set according to the preference or usage habit of the user.
For example, when a user watches a movie indoors through a terminal device, since the brightness of an image in the movie may be adjusted to the brightness most comfortable for the viewer at the late stage of movie production, the brightness value of the backlight finally adjusted at this time may be changed only according to the change of the indoor ambient light, and does not need to be adjusted according to the change of the current scene.
For another example, when a user plays a game indoors through a terminal device, a current game application may have a plurality of scenes with different reference brightness values, such as a cloudy day and a sunny day, because the user needs to accurately capture each target in a game image without being affected by the scene with a lower reference brightness value, the finally adjusted backlight brightness value needs to be referred to the reference brightness value in the current game scene while referring to indoor ambient light, and when the reference brightness value of a certain scene is too low (threshold judgment can be performed on the reference brightness value), the overall backlight brightness value can be improved to reinforce the backlight brightness displayed on the screen, so that the user can capture the target displayed in the image more easily, and the game experience of the user is improved.
Referring to fig. 3, in some embodiments, after step S202 is performed, step S210 may be performed.
Step S210: and judging whether the current foreground application exists in a preset backlight adjustment application list or not.
It will be appreciated that the user's requirements for backlight adjustment may be different for different application information. In this embodiment, a user may select an application that needs to perform the backlight adjustment method provided in this embodiment and add the application to the backlight adjustment application list.
Step S211: and when the current foreground application does not exist in the preset backlight adjustment application list, generating inquiry information.
In this embodiment, the query information may be used to query whether to add the current foreground application to the backlight adjustment application list. The query message may be a text, image or voice message, as one of the ways. After acquiring information of the application program currently running in the foreground, query information can be generated and whether the currently running foreground application needs to be added to the backlight adjustment application list or not can be queried, and a user can select addition or non-addition on a human-computer interaction interface of the terminal device.
In some embodiments, the application added to the backlight adjustment application list is adapted for backlight adjustment of the associated ambient light intensity and application information; but not to the applications in the backlight adjustment application list, is only applicable to backlight adjustment of the associated ambient light intensity.
Referring to fig. 4, in some embodiments, a user may further configure a backlight intensity threshold interval corresponding to the current application program under the current ambient light intensity in a customized manner, and specifically, step S212 and step S213 may be performed.
Step S212: and acquiring a custom configuration instruction.
In this embodiment, the custom configuration instruction may be configured to configure a backlight intensity threshold interval corresponding to the application information under the current ambient light intensity. As a mode, a user-defined configuration item can be provided on a system setting interface of the terminal device, and a corresponding user-defined configuration instruction is generated according to the setting operation of the user.
For example, when a user uses the terminal device indoors, because the intensity of the ambient light at the same position in the room generally does not change much, the user may configure the backlight intensity threshold interval of the current foreground program under the current ambient light intensity, so that the terminal device may apply the same backlight adjustment configuration to the current foreground application when the user uses the terminal device at the same position next time.
Step S213: and acquiring backlight intensity threshold intervals corresponding to the application program information under a plurality of preset ambient light intensity threshold intervals respectively according to the user-defined configuration instruction.
In this embodiment, different preset threshold intervals of the ambient light intensity may correspond to different threshold intervals of the backlight intensity. After the backlight intensity threshold interval configured by the user under the current ambient light intensity is obtained, the corresponding relation between the ambient light intensity corresponding to the current application program information and the backlight intensity threshold interval can be calculated, the backlight intensity threshold interval favored by the user and corresponding to the current application program information under various ambient light intensities can be further predicted, and intelligent backlight adjustment configuration is achieved.
Compared with the backlight adjustment method shown in fig. 1, the backlight adjustment method provided in another embodiment of the present application further realizes more accurate backlight intensity threshold interval division and backlight brightness adjustment according to an application program running in a current foreground in combination with a scene in the application program, and supports user-defined configuration of the number of backlights to be turned on according to user preferences, thereby further expanding the application range of the scheme, realizing more accurate and intelligent backlight adjustment, and effectively improving the user experience of a user.
