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.
Referring to fig. 1, a flowchart of an implementation of a control method provided in an embodiment of the present application is shown, where the method may be applied to an electronic device having a display device capable of outputting content, such as a mobile phone, a pad, a notebook, and the like. The technical scheme in the embodiment is mainly used for improving the use experience of the user in outputting the content by using the electronic equipment.
Specifically, the method in this embodiment may include the following steps:
step 101: a first frame rate is obtained.
Wherein the first frame rate corresponds to an operating system in the electronic device. Specifically, the first frame rate may be understood as a refresh rate configured for a display device of the electronic device, such as a mobile phone screen, in the operating system, that is, a frame rate at which the display device can be refreshed at the highest per unit time when outputting the content.
Specifically, in this embodiment, the frame rate value of the first frame rate may be read from the configuration information of the operating system.
Step 102: a second frame rate is obtained.
The second frame rate is an actual frame rate of the content output by the display device, and is specifically a dynamic frame rate in an operating process of the first application program based on the operating system. For example, with the operation of the first application program, the content output by the display device for the first application program may have a change, and the frame rates of the changed content may be different, in this embodiment, the dynamic frame rate in the operation process of the first application program is obtained, and then the second frame rate is obtained.
For example, the first application program may be a video playing application, where a video frame played by the first application program is constantly changing, for example, switching from outputting a high-definition movie video to outputting a low-definition television video, as shown in fig. 2, so that a frame rate of the video frame is not constant, and in this embodiment, a dynamic frame rate in a process of playing the video frame by the video playing application is obtained to obtain the second frame rate.
Step 103: judging whether the first frame rate is the same as the second frame rate, if so, ending the current flow or returning to re-execute the step 101 and the step 102 so as to continue monitoring the frame rate; if the first frame rate and the second frame rate are different, step 104 is performed.
Step 104: and adjusting the frame rate value of the first frame rate, so that the electronic equipment where the operating system is located outputs the content at the adjusted first frame rate.
That is to say, in this embodiment, when the frame rate corresponding to the operating system is different from the dynamic frame rate in the running process of the first application program, the frame rate corresponding to the operating system is adjusted, so that the electronic device where the operating system is located outputs the content at the first frame rate matched with the dynamic frame rate.
It should be noted that the technical solution in this embodiment may be cycled during the process of outputting the content by the electronic device, that is, in this embodiment, the current first frame rate and the current second frame rate are continuously obtained and the first frame rate is continuously adjusted accordingly, that is, the first frame rate is adjusted by taking the first frame rate and the second frame rate as the same target, so that the first frame rate and the second frame rate can be approximately the same.
For example, as shown in fig. 3a, after step 104, in this embodiment, step 101 may be directly performed back to obtain a new first frame rate (i.e. the first frame rate adjusted last time) and a new second frame rate, and if the new first frame rate and the new second frame rate are different, the frame rate value of the new frame rate is re-filled, so that in this embodiment, the first frame rate corresponding to the operating system is continuously adjusted to enable the first frame rate corresponding to the operating system to be the same as the dynamic frame rate during the running of the first application program.
As another example, as shown in fig. 3b, after step 104, the following steps may be further included in this embodiment:
step 105: and judging whether the loop condition is met, and if so, returning to the step 101 and the subsequent steps, so that the first frame rate is continuously adjusted according to the new first frame rate and the new second frame rate according to the loop condition, and the first frame rate corresponding to the operating system can be the same as the dynamic frame rate in the running process of the first application program.
Wherein the cycling conditions include: a condition of a first duration of time apart. For example, the cycle condition is the duration of N time periods, the length of the time periods can be set according to requirements, and N is a positive integer greater than or equal to 1. Based on this, in this embodiment, step 101 and step 102 are executed every N time periods during the running process of the first application program, and step 104 is executed if it is determined that the first frame rate corresponding to the operating system is monitored every N time periods, so that the first frame rate is monitored every N time periods, further, if it is monitored that the first frame rate is different from the dynamic frame rate during the running process of the first application program, the first frame rate is adjusted once, based on this, the frame rate monitoring and the frame rate adjustment in the current time period are both performed on the basis of the first frame rate after the previous time period is adjusted, and so on, until the running of the first application program is finished or the display device is blacked, at this time, the electronic device stops outputting the content, such as the video playing application is closed, the mobile phone is blacked, or the electronic device is turned off.
It can be seen from the foregoing technical solutions that, in a control method provided in the first embodiment of the present application, first a first frame rate corresponding to an operating system of an electronic device is obtained, then a second frame rate based on a dynamic state of a first application program in an operating process of the operating system is obtained, and if the first frame rate is different from the second frame rate, a frame rate value of the first frame rate is adjusted, so that the electronic device where the operating system is located outputs content at the adjusted first frame rate. Therefore, in the embodiment of the application, the content is output on the electronic device according to the frame rate adjusted based on the dynamic frame rate in the running process of the first application, so that the frame rate corresponding to the operating system is matched with the dynamic frame rate in the running process of the first application, the situation of high power consumption or unsmooth output caused by mismatching is avoided, and the use experience of the user in outputting the content by using the electronic device is improved.
In an implementation manner, in this embodiment, while continuously adjusting the first frame rate, an object configuration file for the electronic device may be obtained according to the first application and the adjusted first frame rate (the latest first frame rate), where the object configuration file includes at least one object operation parameter, and the object operation parameters are used to configure the device. Specifically, after step 104, the method in this embodiment may further include the following steps, as shown in fig. 4 a:
step 106: and acquiring a target configuration file according to the first application program and the adjusted first frame rate, and configuring the equipment according to the target operation parameters in the target configuration file.
Specifically, a plurality of candidate configuration files may be set in the electronic device, each of the candidate configuration files corresponds to an application identifier of one or more application programs, and each of the candidate configuration files also corresponds to a corresponding frame rate range. That is, for each known application program in the electronic device, a corresponding candidate configuration file is preset, and for each frame rate range corresponding to the operating system, a corresponding candidate configuration file is also preset. Each of the candidate configuration files includes at least one target operation parameter, such as an operation parameter related to each hardware component and/or software component in the electronic device, such as an operation frequency of a Central Processing Unit (CPU), a CPU power supply policy, a CPU scheduling policy, a CPU process priority, a DDR (double data rate) synchronous dynamic random access memory (DDR) power supply policy, an operation parameter of an LLCC power supply policy, and the like.
It should be noted that the number and types of the operating parameters in different alternative configuration files may be the same or different, and the parameter values for the same operating parameters in different configuration files may be the same or different.
Based on this, in this embodiment, in the running process of the first application program, a corresponding target configuration file is screened from the multiple candidate configuration files according to the application identifier of the first application program and the latest first frame rate, where the target configuration file simultaneously corresponds to the application identifier of the first application program and the frame rate range where the first frame rate is located, and thus in this embodiment, the running parameters of the hardware component and/or the software component in the electronic device are configured according to each target running parameter in the configuration file.
For example, when the first application is a video playing application and the first frame rate is 30Hz, i.e. the first frame rate is in the corresponding frame rate range of 25Hz to 35Hz, a target configuration file corresponding to the video playing application and the frame rate range of 25 to 35Hz is screened from the plurality of standby configuration files, which at least comprises: the frequency value of the CPU operating frequency and the operating parameters of the DDR power supply strategy.
It should be noted that, with reference to the implementation scheme shown in fig. 3b, in the technical scheme in this embodiment, step 101 and step 102 are executed every N time periods in the running process of the first application, and step 104 and step 106 are executed when the determination in step 103 is yes, as shown in fig. 4b, so that the first frame rate corresponding to the operating system is monitored every N time periods, further, if it is determined that the first frame rate is different from the dynamic frame rate in the running process of the first application, the first frame rate is adjusted once and the device is configured once according to the adjusted first frame rate and the first application, based on this, the frame rate monitoring, the frame rate adjustment and the device configuration in the current time period are all performed on the basis of the first frame rate adjusted in the previous time period, and so on until the running of the first application is finished or the display device is turned black, at this time, the electronic device stops outputting the content, such as the video playing application is closed, the mobile phone is blank, or is turned off.
For example, when a video playing application is started on a mobile phone, a display screen on the mobile phone initially outputs a video picture of the video playing application at a refresh rate of 90Hz, based on which, when a first time period satisfies, for example, the 20 th second, the mobile phone monitors a screen refresh rate and a dynamic frame rate of the video playing application in the process of playing the video picture, if the dynamic frame rate is different from the previously set screen refresh rate of 90Hz, the screen refresh rate can be adjusted to 60Hz, and operating parameters in the mobile phone are configured according to the adjusted screen refresh rate and the adjusted video playing application; as shown in fig. 4c, with the operation of the video playing application, the second time period satisfies, for example, that the screen refresh rate and the new dynamic frame rate of the video playing application in the process of playing the video picture are continuously monitored on the mobile phone on the basis of the adjusted screen refresh rate 60Hz at the 40 th second time period, based on which, if the new dynamic frame rate and the adjusted screen refresh rate 60Hz are different, the screen refresh rate may be readjusted to 30Hz, and the operation parameters in the mobile phone are configured according to the readjusted screen refresh rate and the video playing application; continuing to follow the operation of the video playing application, when a third time period is satisfied as 60 seconds, continuously monitoring the screen refresh rate and a new dynamic frame rate of the video playing application in the process of playing video pictures on the mobile phone on the basis of the readjusted screen refresh rate of 30Hz, if the new dynamic frame rate is different from the readjusted screen refresh rate of 30Hz, readjusting the screen refresh rate to 120Hz again, configuring the operation parameters in the mobile phone according to the readjusted screen refresh rate and the video playing application, and so on, monitoring the screen refresh rate adjusted in the previous time period once when each time period is satisfied, further, if the screen refresh rate is different from the corresponding dynamic frame rate, adjusting the screen refresh rate once and configuring the mobile phone once according to the adjusted screen refresh rate and the video playing application, and the video playing application is closed, the mobile phone is blacked or is powered off, and the like.
In one implementation, when the frame rate value of the first frame rate is adjusted in step 104, the following may be specifically implemented, as shown in fig. 5:
step 501: and comparing the second frame rate with the range boundary values of the plurality of preset frame rate ranges to obtain a target frame rate range corresponding to the second frame rate.
Where there are multiple frame rate gears for the content output of the display device, each frame rate gear corresponds to a preset frame rate range, e.g., a frame rate of 30Hz gears corresponds to a frame rate range of 0-45Hz, a frame rate of 60Hz gears corresponds to a frame rate range of 46-75Hz, a frame rate of 90Hz gears corresponds to a frame rate range of 76-105Hz, a frame rate of 120Hz gears corresponds to a frame rate range above 106Hz, and so on.
Based on this, in this embodiment, the second frame rate is compared with the range boundary value of each preset frame rate range, so as to obtain the frame rate range where the second frame rate is located, that is, the target frame rate range. For example, the second frame rate of 32Hz is compared with the boundary values 0, 45, 46, 75, etc. of the above frame rate ranges, so as to obtain the frame rate range of 32Hz, i.e. the frame rate range of 0-45Hz corresponding to the frame rate notch of 30 Hz.
Step 502: and adjusting the target frame rate corresponding to the target frame rate range to be the frame rate value of the first frame rate.
The target frame rate range corresponds to a frame rate gear, and a frame rate value of the frame rate gear is a target frame rate corresponding to the target frame rate range, so that the target frame rate is set to be a frame rate value of the first frame rate. For example, when the first frame rate is 60Hz and the second frame rate is 32Hz, since the first frame rate is different from the second frame rate, a frame rate range in which 32Hz is located is obtained first: and setting a target frame rate, namely 30Hz, corresponding to the frame rate range of 0-45Hz as a frame rate value of the first frame rate, wherein the frame rate value of the first frame rate is 30Hz after adjustment.
In one implementation manner, when the frame rate value of the first frame rate is adjusted in step 104, the adjustment may be implemented in different manners based on a size relationship between the first frame rate and the second frame rate, as follows:
in one case, if the first frame rate is greater than the second frame rate, a first target frame rate which is less than the first frame rate and has the smallest difference with the first frame rate is obtained from a frame rate set comprising a plurality of preset frame rates, and the first target frame rate is adjusted to be the frame rate value of the first frame rate.
The frame rate set includes a plurality of preset frame rates, such as 30Hz, 60Hz, 90Hz, 120Hz, and the like, each preset frame rate can be understood as a frame rate shift, and each frame rate shift corresponds to a preset frame rate range. Based on this, in this embodiment, when the second frame rate is less than the first frame rate, the first frame rate is adjusted to be lower by one step, that is, the preset frequency at the frame rate step below and closest to the first frame rate is adjusted to be the frame rate value of the first frame rate. With the operation of the first application program and the cyclic execution of the technical scheme of the application, the first frame rate is gradually reduced to a frame rate gear matched with the second frame rate according to a frame rate gear corresponding to a preset frame rate, so that the first frame rate is matched with the second frame rate.
For example, taking the first application program as the video playing application as an example, if the screen refresh rate on the mobile phone, i.e. the first frame rate, is 120Hz and the dynamic frame rate of the video picture in the video playing application, i.e. the second frame rate, is 32Hz, the last gear 90Hz lower than 120Hz is set as the frame rate value of the screen refresh rate on the mobile phone. Based on this, with the video playing of the video playing application, if the dynamic frame rate of the video picture is still 32Hz, the last gear 60Hz which is lower than 90Hz is continuously set as the screen refresh rate on the mobile phone, and so on, until the screen refresh rate on the mobile phone is set to 30Hz, at this time, the frame rate value of the first frame rate is not adjusted any more, and then the new first frame rate is continuously obtained again, and the loop is executed until the video playing application is closed.
In another case, if the first frame rate is less than the second frame rate, a second target frame rate which is greater than the first frame rate and has the smallest difference with the frame rate is obtained in the frame rate set, and the second target frame rate is adjusted to the frame rate value of the first frame rate.
In this embodiment, when the second frame rate is greater than the first frame rate, the first frame rate is increased by one step, that is, the preset frequency at the frame rate step which is higher than the first frame rate and closest to the first frame rate is adjusted to the frame rate value of the first frame rate. With the operation of the first application program and the cyclic execution of the technical scheme of the application, the first frame rate is gradually increased to a frame rate gear matched with the second frame rate according to a frame rate gear corresponding to a preset frame rate, so that the first frame rate is matched with the second frame rate.
For example, taking the first application program as the video playing application as an example, if the screen refresh rate on the mobile phone, i.e. the first frame rate, is 60Hz and the dynamic frame rate of the video picture in the video playing application, i.e. the second frame rate, is 110Hz, the last gear 90Hz higher than 60Hz is set as the frame rate value of the screen refresh rate on the mobile phone. Based on this, with the video playing of the video playing application, if the dynamic frame rate of the video picture is still 110Hz, the last gear 120Hz higher than 90Hz is continuously set as the screen refresh rate on the mobile phone, at this time, the first frame rate and the second frame rate are considered to be consistent, the frame rate value of the first frame rate is not adjusted any more, the new first frame rate is continuously returned and obtained again, and the process is executed in a circulating manner until the video playing application is closed.
In one implementation, when the second frame rate is obtained in step 102, the following may be implemented, as shown in fig. 6:
step 601: and obtaining the average frame rate of the first application program in N continuous time periods in the operating system-based operation process.
Wherein N is a positive integer greater than or equal to 1, and the time period is a historical time period before the current time. For example, a time period may be 10 seconds or 30 milliseconds, and the specific value may be set according to the requirement. That is, in the present embodiment, the average frame rate of each time period is calculated for N time periods before the current time, respectively, as shown in fig. 8.
Step 602: and obtaining a second frame rate according to the average frame rate.
For example, in this embodiment, the average frame rates of the N time periods may be added and averaged, so that an average value between the N average frame rates is taken as the second frame rate; alternatively, in this embodiment, one frame rate is selected as the second frame rate from the average frame rates of the N time periods, for example, a random one, a maximum, a minimum, or a middle frame rate in the order of magnitude is used as the second frame rate.
In one implementation, the first frame rate and the second frame rate may be different, as follows:
in one case, the first frame rate and the second frame rate are different, meaning that: the difference value between the first frame rate and the second frame rate is larger than or equal to the control threshold value corresponding to the first frame rate.
The control threshold corresponding to the first frame rate may be a fixed preset value, and when the first frame rate is in a different frame rate gear, the corresponding control thresholds are the same, for example, the control threshold corresponding to the 120Hz gear and the control threshold corresponding to the 30Hz gear are respectively 15. Based on this, in this embodiment, the difference between the first frame rate and the second frame rate is compared with the control threshold, and if the difference exceeds the control threshold, the first frame rate and the second frame rate are considered to be different, and it can be actually understood that the first frame rate and the second frame rate are not matched in frame rate value. For example, if the first frame rate is 120Hz and the second frame rate is 32Hz, the difference 88 is far above the control threshold 15, and the first frame rate and the second frame rate are considered to be different; as another example, if the first frame rate is 30Hz and the second frame rate is 32Hz, the difference 2 does not exceed the control threshold 15, and the first frame rate and the second frame rate are considered to be the same.
Or, the control threshold corresponding to the first frame rate may not be a fixed value, and when the first frame rate is in a different frame rate shift, the corresponding control thresholds are different. For example, the control threshold for the 120Hz gear is 16, while the control threshold for the 30Hz gear is 5. Based on this, in this embodiment, the difference between the first frame rate and the second frame rate is compared with the control threshold corresponding to the first frame rate, and if the difference exceeds the corresponding control threshold, it is considered that the first frame rate is different from the second frame rate, and actually, it can be understood that the first frame rate is not matched with the second frame rate at the frame rate gear corresponding to the first frame rate. For example, if the first frame rate is 120Hz and the second frame rate is 110Hz, the difference 10 does not exceed the control threshold 16 corresponding to the 120Hz first frame rate, and the first frame rate and the second frame rate are considered to be the same; as another example, if the first frame rate is 30Hz and the second frame rate is 36Hz, the difference 6 has exceeded the control threshold 5 corresponding to the first frame rate of 30Hz, and the first frame rate and the second frame rate are considered to be different.
In one case, the first frame rate and the second frame rate are different, meaning that: the second frame rate is not within the frame rate range corresponding to the first frame rate.
The frame rate range corresponding to the first frame rate may be understood as a frame rate range corresponding to a frame rate shift position where the first frame rate is located, for example, a frame rate shift position of 30Hz corresponds to a frame rate range of 0-45Hz, a frame rate shift position of 60Hz corresponds to a frame rate range of 46-75Hz, a frame rate shift position of 90Hz corresponds to a frame rate range of 76-105Hz, and a frame rate shift position of 120Hz corresponds to a frame rate range above 106 Hz. Based on this, in this embodiment, the range boundary value of the frame rate range corresponding to the second frame rate and the first frame rate is subjected to size determination to determine whether the second frame rate is the same as the first frame rate.
For example, if the first frame rate is 120Hz and the second frame rate is 110Hz, the second frame rate is in a frame rate range of 106Hz or more corresponding to the frame rate of 120Hz, and the first frame rate and the second frame rate are considered to be the same; for another example, if the first frame rate is 30Hz and the second frame rate is 46Hz, the second frame rate is not in the frame rate range of 0-45Hz corresponding to the frame rate of 30Hz, and the first frame rate and the second frame rate are considered to be different.
In one implementation, in addition to adjusting the first frame rate when the second frame rate is different from the first frame rate in this embodiment, the frame rate value of the first frame rate may be adjusted based on a usage state parameter of an operating system or based on a frame rate setting operation of a user. For example, a setting value for the first frame rate is first obtained, and then the setting value is adjusted to the frame rate value of the first frame rate.
Wherein the setting value may be determined based on a use state parameter of the operating system or based on a frame rate setting operation. The usage status parameter of the operating system herein may include a parameter based on an application program run by the operating system, such as a first application program or another application program, where different application programs correspond to different setting values. And the frame rate setting operation refers to an operation generated by setting the frame rate on a setting interface provided by an operating system of the electronic device by a user. Specifically, the user may set the frame rate value of the first frame rate on a setting interface of the operating system according to a requirement, so that the electronic device obtains the setting value thereof according to the frame rate setting operation generated thereby and sets the setting value as the frame rate value of the first frame rate.
For example, when a video playing application is started on a mobile phone, based on the technical scheme in this embodiment, the mobile phone sets a setting value corresponding to the video playing application, such as 90Hz, as a screen refresh rate of the mobile phone, so that a display screen on the mobile phone outputs a video picture of the video playing application with 90Hz as a refresh rate, and at the same time, the mobile phone monitors the screen refresh rate and a dynamic frame rate of the video playing application in a process of playing the video picture, and if the dynamic frame rate is different from a previously set screen refresh rate, the refresh rate can be reset according to the dynamic frame rate, for example, a 120Hz frame rate gear corresponding to a dynamic frame rate of 110Hz is set as the screen refresh rate, so that playing of the video picture with a high frame rate is supported with a high refresh rate, thereby avoiding a situation where the picture is not smooth;
then, the mobile phone continues to monitor the screen refresh rate and the dynamic frame rate of the video playing application in the process of playing the video pictures, because the dynamic frame rate may change as the video playing application continues to play the video pictures, such as change to 66Hz, because the screen refresh rate at this time is 120Hz, which is different from the dynamic frame rate 66Hz, based on this, the screen refresh rate is reset according to the dynamic frame rate, for example, the 90Hz frame rate gear corresponding to the dynamic frame rate 66Hz is set as the screen refresh rate, so that the video pictures are output at the frame rate refresh rate, and the energy consumption of the mobile phone is reduced while smooth picture playing is realized;
then, the mobile phone continues to monitor the screen refresh rate and the dynamic frame rate of the video playing application in the process of playing the video pictures, because the dynamic frame rate may change with the video playing application, for example, to 110Hz, because the screen refresh rate at this time is 90Hz, which is different from the dynamic frame rate of 110Hz, based on this, the screen refresh rate is reset according to the dynamic frame rate, for example, the 120Hz frame rate gear corresponding to the dynamic frame rate of 110Hz is set as the screen refresh rate, so that the playing of the video pictures with high frame rate is supported with high refresh rate, thereby avoiding the situation that the pictures are not smooth;
and so on until the video playing application is closed or the mobile phone is blank.
If the user sets the screen refresh rate through the setting interface on the mobile phone in the above process, the screen refresh rate on the mobile phone is set as the setting value in the setting operation of the user, and along with the running of the video playing application, the screen refresh rate on the mobile phone can be correspondingly set as the frame rate value corresponding to the video playing application, and in the process of playing the video picture by the video playing application, the screen refresh rate and the dynamic frame rate of the video picture are continuously monitored according to the time period, and the screen refresh rate is continuously adjusted accordingly.
Meanwhile, software and hardware parameters such as CPU operation frequency and the like on the mobile phone can be set according to the video playing application and the continuously adjusted screen refresh rate and the corresponding configuration file, so that the power consumption and the picture output performance of the mobile phone are further balanced.
