Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a flowchart of a control method according to a first embodiment of the present application is provided, and 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 for 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. In particular, 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 may be refreshed at a maximum per unit time when outputting content.
Specifically, in this embodiment, the frame rate value of the first frame rate may be read in the configuration information of the operating system.
Step 102: a second frame rate is obtained.
The second frame rate refers to an actual frame rate of content output by the display device, and specifically is a dynamic frame rate in a running process of the first application program based on the operating system. For example, with the running of the first application, the content output by the display device for the first application may change, and the frame rate of the changed content may be different.
For example, the first application may be a video playing application, where the video frames played by the video playing application are continuously changed, such as from outputting high-definition movie video to outputting low-definition drama video, as shown in fig. 2, so that the frame rate of the video frames is not constant, and in this embodiment, the dynamic frame rate during playing of the video frames 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 the first frame rate is the same as the second frame rate, ending the current flow or returning to re-executing the steps 101 and 102 so as to monitor the frame rate continuously; 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, 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 that matches the dynamic frame rate.
It should be noted that, the technical solution in this embodiment may be circulated in the process of outputting the content by the electronic device, that is, in this embodiment, the current first frame rate and the second frame rate are continuously obtained, and the first frame rate is continuously adjusted accordingly, that is, the first frame rate is adjusted with the first frame rate and the second frame rate being the same as the target, so that the first frame rate and the second frame rate approach to be the same.
For example, as shown in fig. 3a, after step 104, the embodiment may directly return to step 101 to obtain a new first frame rate (i.e. the first frame rate adjusted before) 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 refilled and adjusted, so that the first frame rate corresponding to the operating system can be the same as the dynamic frame rate during the running process of the first application program by continuously adjusting the first frame rate corresponding to the operating system in the embodiment.
As another example, as shown in fig. 3b, after step 104, the present embodiment may further include the following steps:
step 105: judging whether the circulation condition is satisfied, and executing step 101 and subsequent steps in a return manner under the condition that the circulation condition is satisfied, thereby continuously adjusting the first frame rate according to the new first frame rate and the new second frame rate according to the circulation condition, so that 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: conditions of the first duration interval. For example, the cycle condition is a duration of N time periods, and the length of the time periods may be set according to the requirement, where N is a positive integer greater than or equal to 1. Based on this, in this embodiment, step 101 and step 102 are executed once every N time periods during the running of the first application program, and step 104 is executed if the determination in step 103 is yes, so that the first frame rate corresponding to the operating system is monitored once every N time periods, further, if it is monitored that the first frame rate is different from the dynamic frame rate during the running 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 all performed on the basis of the first frame rate after the adjustment in the previous time period, and so on, until the running of the first application program is finished or the display device is blacked out, at this time, the electronic device stops outputting the content, such as the video playing application is closed, the mobile phone blacked out or shutdown.
It can be seen from the above technical solution that, in the 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 dynamic second frame rate during a running process of a first application program based on the operating system is obtained, and if the first frame rate and the second frame rate are different, then the 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 program, 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 program, the conditions of high power consumption or unsmooth output caused by mismatching are avoided, and the use experience of a user for outputting the content by using the electronic device is improved.
In one implementation, while the first frame rate is continuously adjusted in this embodiment, a target configuration file for the electronic device may be obtained according to the first application program and the adjusted first frame rate (the latest first frame rate), where the target configuration file includes at least one target operation parameter, and these target 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 obtaining 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 alternative configuration files may be provided in the electronic device, where each alternative configuration file corresponds to an application identifier of one or more application programs, and each alternative configuration file also corresponds to a corresponding frame rate range. That is, for each known application in the electronic device, a corresponding alternative configuration file is preset, and for each frame rate range corresponding to the operating system, a corresponding alternative configuration file is also preset. Each of the configuration files includes at least one target operating parameter, such as an operating parameter related to each hardware component and/or software component in the electronic device, such as an operating frequency of the CPU CPU (central processing unit), a CPU power policy, a CPU scheduling policy, a CPU process priority, a double rate synchronous dynamic random access memory DDR power policy, an operating parameter of an LLCC power policy, and so on.
It should be noted that the number and types of the operating parameters in the different alternative configuration files may be the same or different, and the parameter values for the same operating parameters in the different configuration files may be the same or different.
Based on this, in the running process of the first application program in this embodiment, the corresponding target configuration file is selected 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 corresponds to the application identifier of the first application program and the frame rate range where the first frame rate is located, so that 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 program is a video playing application and the first frame rate is 30Hz, that is, in the corresponding frame rate range of 25Hz-35Hz, the target configuration files corresponding to the video playing application and the frame rate range of 25-35 are selected from the plurality of standby configuration files, where at least the target configuration files include: the frequency value of the CPU operating frequency and the operating parameters of the DDR power supply strategy.
It should be noted that, in conjunction with the implementation scheme shown in fig. 3b, the technical scheme in this embodiment executes step 101 and step 102 once every N time periods during the running process of the first application program, and executes step 104 and step 106 if the first time period is determined to be positive in step 103, as shown in fig. 4b, thereby monitoring the first frame rate corresponding to the operating system once 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, adjusting the first frame rate once, and configuring the device once according to the adjusted first frame rate and the first application program, based on this, the frame rate monitoring, the frame rate adjustment, and the device configuration on the current time period are all performed on the basis of the adjusted first frame rate of the previous time period, and so on until the running of the first application program is finished or the display device is blacked out, at this time, the electronic device stops outputting content, such as the video playing application is turned off, blacked out or turned off, and so on.
For example, when a video playing application is started on a mobile phone, a display screen on the mobile phone outputs video pictures of the video playing application with a refresh rate of 90Hz initially, based on the video pictures, when a first time period is satisfied, such as 20 seconds, 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 pictures, 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 operation parameters in the mobile phone are configured according to the adjusted screen refresh rate and the video playing application; as shown in fig. 4c, with the video playing application running, continuing to monitor the screen refresh rate and the new dynamic frame rate of the video playing application in playing the video frames on the basis of the adjusted screen refresh rate of 60Hz on the mobile phone at the second time period meeting the requirement of 40 seconds, based on which, if the new dynamic frame rate and the adjusted screen refresh rate of 60Hz are different, the screen refresh rate can be readjusted to 30Hz, and the running parameters in the mobile phone can be configured according to the readjusted screen refresh rate and the video playing application; continuing to run with the video playing application, when the third time period satisfies 60 seconds, continuing to monitor the screen refresh rate and the new dynamic frame rate of the video playing application in the process of playing video pictures 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 running parameters in the mobile phone according to the readjusted screen refresh rate and the video playing application again, and so on, and monitoring the screen refresh rate adjusted in the previous time period once when each time period satisfies, 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 until the video playing application is closed, the mobile phone is turned off or turned off, and the like.
In one implementation, when adjusting the frame rate value of the first frame rate in step 104, this may be specifically implemented as follows, as shown in fig. 5:
step 501: and comparing the second frame rate with range boundary values of a plurality of preset frame rate ranges to obtain a target frame rate range corresponding to the second frame rate.
Wherein the content output for the display device has a plurality of frame rate steps, each frame rate step corresponding to a preset frame rate range, e.g. a frame rate of 30Hz steps corresponding to a frame rate range of 0-45Hz, a frame rate of 60Hz steps corresponding to a frame rate range of 46-75Hz, a frame rate of 90Hz steps corresponding to a frame rate range of 76-105Hz, a frame rate of 120Hz steps corresponding to a frame rate range above 106Hz, etc.
Based on this, in this embodiment, the second frame rate is compared with the range boundary values of the respective preset frame rate ranges, thereby obtaining the frame rate range in which 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 of 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 gear 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 frame rate value of the frame rate gear is the target frame rate corresponding to the target frame rate range, and therefore the target frame rate is set to be the 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, the frame rate range in which 32Hz is located is obtained first: and setting the target frame rate corresponding to the frame rate range of 0-45Hz, namely 30Hz, as the frame rate value of the first frame rate, and setting the frame rate value of the first frame rate to be 30Hz after adjustment based on the target frame rate of the frame rate range of 0-45 Hz.
In one implementation, when adjusting the frame rate value of the first frame rate in step 104, it may be implemented in different manners based on the magnitude relation 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 that is less than the first frame rate and has a minimum difference from the first frame rate is obtained from a frame rate set including a plurality of preset frame rates, and the first target frame rate is adjusted to a 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, etc., each of which may be understood as a frame rate range, and each of which corresponds to a preset frame rate range. Based on this, in the present embodiment, when the second frame rate is smaller than the first frame rate, the first frame rate is adjusted by one gear, that is, the preset frequency in the gear of the frame rate below 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 running 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 the frame rate gear corresponding to the preset frame rate, so that the matching of the first frame rate and the second frame rate is realized.
For example, taking a first application program as an example of a video playing application, if the screen refresh rate on the handset, i.e. the first frame rate, is 120Hz and the dynamic frame rate of the video pictures in the video playing application, i.e. the second frame rate, is 32Hz, then the last gear 90Hz below 120Hz is set as the frame rate value of the screen refresh rate on the handset. Based on this, with video playing of the video playing application, if the dynamic frame rate of the video picture is still 32Hz, then the last gear 60Hz lower than 90Hz is continuously set to 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 which time the first frame rate and the second frame rate are considered to be consistent, then the frame rate value of the first frame rate is not adjusted any more, then the process continues to re-acquire the new first frame rate, and so on, and the process is circulated until the video playing application is turned off.
In another case, if the first frame rate is less than the second frame rate, a second target frame rate that is greater than the first frame rate and that has a minimum difference from the frame rate is obtained in the set of frame rates, 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 gear, that is, the preset frequency in the gear above the first frame rate and closest to the first frame rate is adjusted to be the frame rate value of the first frame rate. With the running of the first application program and the cyclic execution of the technical scheme of the application, the first frame rate is gradually increased to the frame rate gear matched with the second frame rate according to the frame rate gear corresponding to the preset frame rate, so that the matching of the first frame rate and the second frame rate is realized.
For example, taking a first application program as an example of a video playing application, if the screen refresh rate on the handset, i.e. the first frame rate, is 60Hz and the dynamic frame rate of the video pictures in the video playing application, i.e. the second frame rate, is 110Hz, then the last gear 90Hz above 60Hz is set as the frame rate value of the screen refresh rate on the handset. Based on this, with the video playing of the video playing application, if the dynamic frame rate of the video picture is still 110Hz, then the last gear 120Hz higher than 90Hz is continuously set to be 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, then the frame rate value of the first frame rate is not adjusted any more, then the new first frame rate is continuously obtained again, and the cycle is performed until the video playing application is closed.
In one implementation, when the second frame rate is obtained in step 102, this may be achieved as shown in fig. 6 by:
step 601: an average frame rate of the first application over a continuous N time periods during the operating system based run is obtained.
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 particular value may be set as desired. That is, the average frame rate for each time period is calculated for N time periods before the current time in the present embodiment, respectively, as shown in fig. 8.
Step 602: the second frame rate is obtained from the average frame rate.
For example, the average frame rates of the N time periods may be summed and averaged in the present embodiment, so that an average value between the N average frame rates is taken as the second frame rate; alternatively, one frame rate is selected as the second frame rate among the average frame rates of the N time periods in the present embodiment, for example, a frame rate in which one, the maximum, the minimum, or the middle of the size order is random is selected as the second frame rate.
In one implementation, there may be a plurality of cases where the first frame rate and the second frame rate differ in meaning, as follows:
in one case, the first frame rate and the second frame rate being different means that: the difference between the first frame rate and the second frame rate is greater than or equal to a control threshold 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 gear with a different frame rate, 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, which can be understood as actually that the first frame rate and the second frame rate do not match in frame rate value. For example, if the first frame rate is 120Hz and the second frame rate is 32Hz, then the difference 88 is far above the control threshold 15, at which point the first frame rate and the second frame rate are considered to be different; for another example, if the first frame rate is 30Hz and the second frame rate is 32Hz, then the difference 2 does not exceed the control threshold 15, at which point the first frame rate and the second frame rate are considered to be the same.
Alternatively, 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 gear, the corresponding control threshold is different. For example, a control threshold value for a 120Hz gear is 16, and a control threshold value for a 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, the first frame rate and the second frame rate are considered to be different, which can be understood as that the first frame rate and the second frame rate are not matched in 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, then the difference 10 does not exceed the control threshold 16 corresponding to the first frame rate of 120Hz, at which point the first and second frame rates are considered to be the same; for another example, if the first frame rate is 30Hz and the second frame rate is 36Hz, then the difference 6 has exceeded the control threshold 5 corresponding to the first frame rate of 30Hz, at which point the first frame rate is considered to be different from the second frame rate.
In one case, the first frame rate and the second frame rate being different means 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 range in which the first frame rate is located, for example, a frame rate range of 0-45Hz is corresponding to a frame rate range of 30Hz, a frame rate range of 46-75Hz is corresponding to a frame rate range of 60Hz, a frame rate range of 76-105Hz is corresponding to a frame rate range of 90Hz, and a frame rate range of 106Hz or more is corresponding to a frame rate range of 120 Hz. Based on this, in the present embodiment, the size judgment is made on the range boundary value of the frame rate range corresponding to the second frame rate and the first frame rate 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, then the second frame rate is in a frame rate range of 106Hz or more corresponding to a frame rate gear of 120Hz, where 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, then the second frame rate is not in the range of 0-45Hz frame rate corresponding to the frame rate gear 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, the frame rate value of the first frame rate may be adjusted based on a usage status parameter of the operating system or based on a user's frame rate setting operation. For example, a setting value for the first frame rate is obtained first, and then the setting value is adjusted to a frame rate value of the first frame rate.
Wherein the setting value may be determined based on a usage status parameter of the operating system or based on a frame rate setting operation. The usage status parameter of the operating system may include a parameter based on an application program executed by the operating system, such as a first application program or other application programs, where different application programs correspond to different setting values, and in this embodiment, when it is monitored that a certain application program is executed on the operating system, in a correspondence table between an application program and a frame rate, the setting value corresponding to the application program is read and adjusted to the frame rate value of the first frame rate. And the frame rate setting operation refers to an operation generated by a user performing frame rate setting on a setting interface provided by an operating system of the electronic device. Specifically, the user may set the frame rate value of the first frame rate on the setting interface of the operating system according to the requirement, and thereby, the electronic device obtains the setting value thereof according to the frame rate setting operation thus generated and sets it 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 the 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 video pictures of the video playing application at the refresh rate of 90Hz, meanwhile, the mobile phone monitors the screen refresh rate and a dynamic frame rate of the video playing application in the process of playing the video pictures, if the dynamic frame rate is different from the 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 the dynamic frame rate 110Hz is set as the screen refresh rate, and thus, the playing of the video pictures with high frame rate is supported at high refresh rate, so that the situation of unsmooth pictures is avoided;
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 video pictures, and as the video playing application continues to play video pictures, the dynamic frame rate may change, for example, to 66Hz, and as the screen refresh rate is 120Hz, which is different from the dynamic frame rate 66Hz, 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 refresh rate of the frame rate, and the mobile phone energy is reduced while the smooth playing of the pictures 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 video pictures, and as the video playing application continues to play video pictures, the dynamic frame rate may change, for example, to 110Hz, and as the screen refresh rate at this time is 90Hz and is different from the dynamic frame rate 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 110Hz is set as the screen refresh rate, so that the playing of the video pictures with high frame rate is supported at high refresh rate, and the situation of unsmooth pictures is avoided;
And so on until the video playback application is turned off or the handset is black.
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 as the video playing application operates, 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 pictures by the video playing application, the screen refresh rate and the dynamic frame rate of the video pictures are continuously monitored according to the time period, and the screen refresh rate is continuously adjusted accordingly.
Meanwhile, the mobile phone can set software and hardware parameters such as CPU running frequency and the like on the mobile phone according to the video playing application and the continuously adjusted screen refresh rate and corresponding configuration files, so as to further balance the power consumption and picture output performance of the mobile phone.
