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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
An execution main body of the method for adjusting the screen refresh rate may be the device for adjusting the screen refresh rate provided by the embodiment of the present application, or an electronic device integrated with the device for adjusting the screen refresh rate, where the device for adjusting the screen refresh rate may be implemented in a hardware or software manner. The electronic device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a method for adjusting a screen refresh rate according to an embodiment of the present disclosure. The specific process of the method for adjusting the screen refresh rate provided by the embodiment of the application can be as follows:
in 101, when detecting that an application is switched to a foreground operation, acquiring historical use information of the foreground application and a current refresh rate of a screen.
The display process of mobile terminals such as mobile phones mainly comprises picture drawing operation, picture synthesis operation and picture display operation. For example, when displaying screen content, each application (such as a desktop, a video, an application program, or the like) first performs a drawing operation to draw respective display content, and after all applications complete the drawing operation, the system synthesizes the contents drawn by all applications into one display frame and outputs the display frame to the screen for display. The refresh rate of the screen is the number of times per second that the display image is drawn, i.e., the number of screen refreshes per second, in Hz (hertz). Generally, a higher refresh rate has a larger number of frames in the same time, and a higher frame rate results in less image sticking, smoother animation, but more power consumption.
According to the method and the device, historical use information of the user on each application is counted to determine the use habit of the user on the application, a proper refresh rate is set for the application according to the use habit of the user on the application, and when the application is located in foreground operation, the refresh rate is used as a target refresh rate to adjust the refresh rate of a screen.
In this embodiment, when the electronic device is operated in a bright screen state, when it is detected that an application is switched to foreground operation, historical usage information of the application switched to foreground is acquired, where the historical usage information includes usage frequency and/or accumulated usage time of the application by a user in a historical time period. The usage frequency can be counted in a week or day period. The historical time period may be the last half year or the last three months, etc.
The application switching to the foreground application may include various scenarios, for example, a user clicks an icon of an application from a desktop to open the application, and the application is in a closed state before the application is opened, and then the application is switched from the closed state to the foreground after the user performs the operation. For another example, the user switches application a, which is running in the foreground, from the foreground to the background, while switching application B, which is running in the background, from the background to the foreground, and so on. And when detecting that the application is switched to the foreground operation, the current refresh rate of the screen.
At 102, a first target refresh rate corresponding to a foreground application is determined based on historical usage information.
The method comprises the steps of presetting a mapping relation between historical use information and a first target refresh rate in the electronic equipment, and searching the corresponding first target refresh rate according to the relation after determining the historical use information of foreground application, wherein if the use frequency of one application is higher, the application is relatively frequently used by a user, and in order to enable the user to have better use experience when using the application, the relatively higher screen refresh rate can be set for the application. Conversely, a smaller refresh rate may be set for the application. When the cumulative usage period of an application is longer, a higher refresh rate is set for it as well.
For example, in some embodiments, a mapping relationship between a refresh rate and a usage frequency interval or an accumulated usage duration interval is set, after historical usage information of a foreground application is acquired, an interval to which the historical usage information belongs is determined, and then a refresh rate corresponding to the interval is searched. In this embodiment, the minimum refresh rate is 60Hz, and the values of the refresh rate may be 60Hz, 61Hz, 62Hz, … … 120Hz … … 240Hz, and the like. For example, in some embodiments, the refresh rate may take on values of 60Hz, 90Hz, 120Hz, 240 Hz.
For example, when the cumulative service life of the application is greater than or equal to 0 and less than 10 hours, the corresponding refresh rate is 60Hz, when the cumulative service life of the application is greater than or equal to 10 hours and less than 50 hours, the corresponding refresh rate is 90Hz, and when the cumulative service life of the application is greater than or equal to 50 hours, the corresponding refresh rate is 120 Hz. And so on.
At 103, it is determined whether the current refresh rate coincides with a first target refresh rate.
At 104, when the current refresh rate does not coincide with the first target refresh rate, the refresh rate of the screen is adjusted to the first target refresh rate.
After the first target refresh rate is determined, whether the current refresh rate is consistent with the first target refresh rate or not is judged, if the current refresh rate is inconsistent with the first target refresh rate, the current refresh rate of the screen is adjusted, for example, if the current refresh rate is smaller than the first target refresh rate, the refresh rate is increased to the first target refresh rate, and if the current refresh rate is larger than the first target refresh rate, the refresh rate is decreased to the first target refresh rate.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the method for adjusting a screen refresh rate provided in the embodiment of the present application, when it is detected that an application is switched to a foreground, historical usage information of the foreground application and a current refresh rate of a screen are obtained, a first target refresh rate corresponding to the foreground application is determined according to the historical usage information, whether the current refresh rate is consistent with the first target refresh rate is determined, and when the current refresh rate is inconsistent with the first target refresh rate, the refresh rate of the screen is adjusted to the first target refresh rate.
The method according to the preceding embodiment is illustrated in further detail below by way of example.
Referring to fig. 2, fig. 2 is a second flow chart illustrating a method for adjusting a screen refresh rate according to an embodiment of the invention. The method comprises the following steps:
in 201, when detecting that an application is switched to a foreground operation, acquiring historical use information of the foreground application and a current refresh rate of a screen.
When the electronic equipment is in the bright screen state operation, when the electronic equipment detects that the application is switched to the foreground operation, acquiring historical use information of the application switched to the foreground, for example, a user clicks an icon of an application from a desktop to open the application, and when the application is switched to the closed state before, switching the application from the closed state to the foreground after the user executes the operation.
At 202, a first target refresh rate corresponding to a foreground application is determined based on historical usage information.
The method comprises the steps that a mapping relation between historical use information and a first target refresh rate is preset in the electronic equipment, and after the historical use information of foreground application is determined, the corresponding first target refresh rate is searched according to the relation.
At 203, it is determined whether the current refresh rate coincides with a first target refresh rate.
And when the current refresh rate is the same as the first target refresh rate, the current refresh rate and the first target refresh rate are considered to be consistent, or when the current refresh rate and the first target refresh rate both belong to the same preset refresh rate interval, the current refresh rate and the first target refresh rate are judged to be consistent.
In 204, when the current refresh rate is greater than the first target refresh rate, the refresh rate of the screen is gradually decreased from the current refresh rate to the first target refresh rate according to the preset adjustment amplitude.
In 205, when the current refresh rate is less than the first target refresh rate, the refresh rate of the screen is adjusted to the first target refresh rate.
For a scene adjusted from a low refresh rate to a high refresh rate, the refresh rate can be directly set as the high refresh rate, but for a scene adjusted from the high refresh rate to the low refresh rate, if the high refresh rate is directly reduced to the low refresh rate, the display screen is easy to display in an unnatural and unsmooth manner, and very bad experience is brought to a user. Therefore, when the refresh rate of the screen needs to be reduced from the higher current refresh rate to the first target refresh rate, the intermediate refresh rate needs to be gradually reduced to buffer the change of the refresh rate, so that the user can have a process of slowly accepting the change, and the problems of unnatural and unsmooth display of the display screen are avoided.
For example, in some embodiments, 204 may include the following refinement steps:
a. when the current refresh rate is larger than the first target refresh rate, determining one or more intermediate refresh rates from large to small according to the preset adjusting amplitude and the current refresh rate;
b. and gradually reducing the refresh rate of the screen from the current refresh rate to a first target refresh rate according to one or more intermediate refresh rates from large to small.
In this embodiment, it is assumed that the preset adjustment amplitude is 5Hz, the current refresh rate is 90Hz, and the first target refresh rate is 60 Hz; then, according to the preset adjustment amplitude and the current refresh rate, the following intermediate refresh rates can be determined: 85Hz, 80Hz, 75Hz, 70Hz, 65H. Then, within a preset time (for example, 1 minute), the refresh rate is gradually (uniformly) decreased from 90Hz to 85Hz, then decreased from 85Hz to 80Hz, then decreased from 80Hz to 75Hz, then decreased from 75Hz to 70Hz, then decreased from 70Hz to 65Hz, and then decreased from 65Hz to 60 Hz. The above numbers are all examples, and in other embodiments, a suitable preset adjustment range may be set as needed.
Alternatively, in other embodiments, the refresh rate of the screen may be linearly gradually decreased from the current refresh rate to the first target refresh rate.
At 206, when it is detected that the foreground application is closed or switched to the background operation, the refresh rate of the screen is adjusted to the minimum refresh rate.
After the foreground runs for a period of time, if the electronic device detects that the foreground application is closed or detects that the foreground application is switched to the background, and the current display interface is switched to the desktop, the refresh rate of the screen is adjusted to be the minimum refresh rate, namely 60Hz, so that when the user does not use the application, the power consumption is reduced, and through the dynamic mode, when the application frequently used by the user or the application operated for a long time runs in the foreground, the screen is adjusted to be a higher refresh rate, and the user experience is improved; on the contrary, for example, when the desktop is displayed or the application which is not used by the user and has short service time runs in the foreground, the screen is adjusted to a lower refresh rate, so that the power consumption is reduced, and the balance between the user experience and the power consumption is ensured.
If the foreground application is switched to the background and other applications are switched to the foreground, the dynamic adjustment of the refresh rate of the screen is controlled according to the processes 201 to 206 again so as to adapt to the use condition of the electronic equipment by the user.
As can be seen from the above, in the method for adjusting the screen refresh rate provided in this embodiment, when the refresh rate of the screen is adjusted to be lower, in order to avoid the problem that the image display is not smooth due to the fact that the reduction range is too large because the refresh rate is directly reduced from a higher refresh rate to a lower refresh rate, the intermediate refresh rate is determined first, and the electronic device is sequentially adjusted from the current refresh rate to each of the intermediate refresh rates in the order from the current refresh rate to the first target refresh rate until the current refresh rate is adjusted to the first target refresh rate, so as to buffer the change of the refresh rate.
In some embodiments, before obtaining the historical usage information of the foreground application and the current refresh rate of the screen, further comprising: judging whether the foreground application is in a preset blacklist or not; if not, acquiring historical use information of the foreground application and the current refresh rate of the screen.
In this embodiment, to further reduce power consumption, a user may add some applications with a long duration to the blacklist, for example, some video playing applications, or game applications, and these applications may generally have a high cumulative usage time or usage frequency due to an excessively long duration, and if the applications are continuously refreshed at a high refresh rate, the power consumption may be excessively high. Therefore, if a user wants to guarantee the standby time of the mobile phone, the applications can be added into the blacklist, and even if the applications are switched to be operated in the foreground, the refresh rate of the applications cannot be increased.
Referring to fig. 3, fig. 3 is a third flow chart illustrating a method for adjusting a screen refresh rate according to an embodiment of the invention. The method comprises the following steps:
in 301, when detecting that an application is switched to a foreground operation, acquiring historical use information of the foreground application and a current refresh rate of a screen.
At 302, a first target refresh rate corresponding to a foreground application is determined based on historical usage information.
In 303, a current ambient light level is obtained and a second target refresh rate corresponding to the ambient light level is determined.
Because human eyes have different sensitivities to screen stroboflash under different light brightness conditions. On the basis of the foregoing embodiment, after the first target refresh rate is determined, the current ambient light brightness is detected, and a second target refresh rate is determined according to the detected ambient light brightness and the mapping relationship between the preset ambient light brightness and the target refresh rate.
At 304, it is determined whether the first target refresh rate is not less than the second target refresh rate.
When the first target refresh rate is not less than the second target refresh rate, execute 306; when the first target refresh rate is less than the second target refresh rate, 308 is performed.
At 305, it is determined whether the current refresh rate coincides with a first target refresh rate.
At 306, when the current refresh rate does not coincide with the first target refresh rate, the refresh rate of the screen is adjusted to the first target refresh rate.
At 307, it is determined whether the current refresh rate is consistent with a second target refresh rate.
At 308, when the current refresh rate is inconsistent with the second target refresh rate, the refresh rate of the screen is adjusted to the second target refresh rate.
After the second target refresh rate is determined, the higher of the first target refresh rate and the second target refresh rate is taken as the refresh rate to be finally adjusted. For example, if the first target refresh rate is not less than the second target refresh rate, the refresh rate of the screen is adjusted to the first target refresh rate when the current refresh rate is not identical to the first target refresh rate. And if the first target refresh rate is smaller than the second target refresh rate, adjusting the refresh rate of the screen to be the second target refresh rate when the current refresh rate is inconsistent with the second target refresh rate. The refresh rate corresponding to different ambient light brightness may be an empirical value, where the refresh rate may be positively correlated with the ambient light brightness, that is, the brighter the ambient light brightness is, the higher the refresh rate is to avoid stroboflash.
Therefore, the method for adjusting the screen refresh rate provided by the embodiment integrates the use condition of the user to the application and the ambient light brightness, and dynamically adjusts the refresh rate of the electronic device, so that the screen is ensured not to have stroboflash under various ambient light brightness, and the picture is ensured to have better fluency.
