Description

Technical Field

[0001] The present application relates to frame rate processing technology, and in particular to an information processing method and electronic device. Background Art

[0002] Existing electronic devices support frame rate refreshes of 60, 90, and 120fps, but some applications in certain scenarios support different frame rates, some support frame rate refreshes of 90 and 120fps, and some support frame rate refreshes of 60, 90, and 120fps. If an application that supports the higher 90 and 120fps runs at a lower 60fps, frame loss and stuttering will occur. For example, when a map application is scaling the interface, if the current running interface is at 90fps, serious frame loss will occur, and the user will also visually feel obvious screen stuttering. In the prior art, users are usually required to manually switch to select a suitable frame rate, which is not only cumbersome to operate, but also gives users a poor user experience. Therefore, providing a method that can automatically switch the frame rate is an issue that needs to be urgently addressed. Summary of the invention

[0049] The third frame rate threshold is smaller than the fourth frame rate threshold, and both the third frame rate threshold and the fourth frame rate threshold are set according to the second frame rate.

[0050] In the above scheme, the scheme also includes:

[0062] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0063] Figure 1 This is a schematic diagram of the process implementation of the processing method in this application, such as Figure 1 As shown, including:

[0064] Step 101, if the display screen of the electronic device is at a first refresh rate, generating display content of the output interface of the current application based on the first frame rate;

[0065] In the present application, the electronic device may be a device with a display screen such as a computer, a television, a mobile phone, a watch, a bracelet, etc., and the electronic device may run multiple applications. When the electronic device runs at least one application, the display screen of the electronic device may generate display content of the output interface of the current application.

[0066] Specifically, the display screen of the electronic device can generate the display content of the output interface of the current application at different frame rates when it is at different refresh rates. In other words, the correspondence between various refresh rates of the display screen and each frame rate can also be stored in the database of the electronic device. When the display screen of the electronic device is at a first refresh rate, the electronic device can obtain the first frame rate corresponding to the first refresh rate based on the database, and generate the display content of the output interface of the current application at the first frame rate.

[0067] For example, the display screen of the electronic device is refreshed at 90H per second at the first refresh rate. Z The screen can be refreshed at a speed of , and when running the current application, the display content of the output interface of the current application can be generated at a speed of transmitting 90 frames per second.

[0068] Step 102, monitoring frame loss in the process of generating display content of the output interface of the current application based on the first frame rate, and obtaining a first parameter value related to the frame loss;

[0069] In the present application, the electronic device can also continuously or periodically monitor frame loss of the display content during the process of generating the display content of the output interface of the current application based on the first frame rate, and obtain a first parameter value related to the frame loss based on the monitoring result.

[0070] Here, the first parameter value related to frame loss can represent the length of time it takes for the display screen of the electronic device to lose N frames within a first time period when the display screen is generating display content of the output interface of the current application at a first frame rate, where N is greater than or equal to 2.

[0071] Specifically, in the process of generating the display content of the output interface of the current application based on the first frame rate, the electronic device can calculate the time taken by the display screen to lose N frames in the first time period, and use the time taken by the display screen to lose N frames in the first time period as the first parameter value. The time taken by the N frames to be lost can represent the total time from the loss of the first frame to the end of the loss of N frames, or can represent the total time from the transmission of the first frame to the end of the loss of N frames.

[0072] For example, the electronic device can calculate the time taken to lose 7 frames within 300 milliseconds when generating the display content of the output interface of the current application at a frame rate of 90. If the electronic device monitors that the display screen loses 1 frame at the 10th millisecond during the display content of the output interface of the current application at a frame rate of 90, the electronic device can start timing from the 10th millisecond to calculate the time taken to lose 7 frames. If the display screen is monitored to lose 7 frames at the 50th millisecond, the electronic device can determine that the time taken to lose 7 frames within 300 milliseconds is 40 milliseconds (i.e., the total time from the loss of the first frame to the end of the loss of 7 frames). If the electronic device starts timing from the transmission of the first frame of the picture during the display content of the output interface of the current application at a frame rate of 90 to calculate the time taken to lose 7 frames, if the display screen is monitored to lose 7 frames at the 50th millisecond, it is determined that the time taken to lose 7 frames within 300 milliseconds is 50 milliseconds (i.e., the total time from the transmission of the first frame to the end of the loss of 7 frames). In this way, the present application obtains the duration of the display screen losing fixed frames in the first time period by monitoring the frame loss in the process of the electronic device generating the display content of the output interface of the current application based on the first frame rate. Based on the duration of the display screen losing fixed frames in the first time period, it can be determined whether the display content of the current output interface is stuck, thereby preparing for the subsequent refresh rate switching operation.

[0073] In the present application, the first parameter value related to frame loss can also represent the number of frames lost by the display screen of the electronic device within a first time period when the display screen of the electronic device generates display content of the output interface of the current application at a first frame rate.

[0074] Specifically, in the process of generating the display content of the output interface of the current application based on the first frame rate, the electronic device can also calculate the number of frame losses of the display screen in the first time period; and use the number of frame losses of the display screen in the first time period as the first parameter value.

[0075] For example, when the display screen of the electronic device generates the display content of the output interface of the current application at a 90 frame rate, the number of frame drops of the display screen within 300 milliseconds can be calculated, and the number of frame drops within 300 milliseconds (for example, 7 frames) can be used as the first parameter value. In this way, based on the number of frame drops of the display screen within a certain period of time, it can be determined whether the display content of the current output interface of the display screen is stuck, so as to prepare for the subsequent refresh rate switching operation.

[0076] In the present application, the first parameter value related to frame loss can also characterize the frame loss rate per second and the frame loss rate per N seconds of each page layer in the current application within the first time period when the display screen of the electronic device generates the display content of the output interface of the current application at the first frame rate.

[0077] Specifically, the current application being executed by the electronic device may have multiple page layers. In the process of generating the display content of the output interface of the current application based on the first frame rate, the electronic device can also monitor the frame loss of each page layer in the current application within a first time period to obtain the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, where N is greater than or equal to 2; and then use the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period as the first parameter value.

[0078] For example, the current application has a total of 4 page layers. In the process of generating the display content of the output interface of the current application based on the first frame rate, the electronic device may have frame loss in all page layers, or only one page layer may have frame loss, or no frame loss in all pages. Therefore, the electronic device can define two standards for frame loss in page layers, wherein standard one can be: at least one page layer has frame loss in the update drawing of the screen, which includes two arrays (frame loss rate per second and frame loss rate per N seconds), and standard two can be: all page layers have frame loss in the update drawing of the screen, which includes two arrays (frame loss rate per second and frame loss rate per N seconds), and standard two has a higher priority than standard one.

[0079] Here, the priority of standard 2 is higher than that of standard 1, which specifically means: if the electronic device controls the display screen to switch from the first refresh rate to the second refresh rate when standard 2 is met, it is necessary to control the display screen to switch from the second refresh rate to the first refresh rate when the second standard is met before standard 1 can be enabled, and the display screen can be controlled to perform refresh rate switching when the electronic device meets standard 1. In this way, by monitoring the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, it can be determined whether the display content of the current output interface is stuck, and based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, the standards met by the current application are determined, which can improve the accuracy of judging the stuck phenomenon and the severity of the stuck phenomenon.

[0080] In the present application, when the electronic device monitors the frame loss of each page layer in the current application within the first time period to obtain the frame loss rate per second and the frame loss rate per N seconds of each page layer within the first time period, it can specifically monitor the number of frame losses in each pulse signal of each page layer within the first time period in the process of generating the display content of the output interface of the current application based on the first frame rate; generate the frame loss rate per second of each page layer in the first time period based on the number of frame losses of each page layer in each pulse signal; and generate the frame loss rate per N seconds of each page layer in the first time period based on the frame loss rate per second of each page layer in the first time period.

[0081] For example, in the process of generating the display content of the output interface of the current application based on the first frame rate, the number of frame losses in each page layer within 1 second and the number of frame losses in each 10 seconds are monitored. Specifically, the number of frame losses in the pulse signal transmitted by each page layer within 1 second is monitored. For example, taking a 90 frame rate as an example, each page layer has 90 frames of pictures within 1 second, which corresponds to 90 pulse signals. If it is detected that at least one page layer has 5 pulse signals with frame losses within 1 second, the frame loss rate per second of at least one page layer is determined to be 5, and the frame loss rate per second is counted as 5 in Standard 1. If at least one page layer still has frame losses in the next 1 second, and the number of frame losses (for example, 7) is greater than 5, the frame loss rate per second recorded in Standard 1 is updated to the current maximum value (for example, 7). In other words, as long as there is a page layer with frame losses in Standard 1, it is counted, and the current maximum frame loss rate is recorded. Then, when 10 seconds is reached, all frame loss rates within 1-10 seconds are counted, and the sum of the frame loss rates within 1-10 seconds is used as the frame loss rate of at least one page layer in every 10 seconds. In standard one, the frame loss rate in every 10 seconds is counted as 1.

[0082] Here, standard one and standard two can be performed synchronously. If the electronic device detects that all page layers have frame loss within 1 second, the frame loss rate per second is counted at standard one, and the frame loss rate per second of standard two is also counted (for example, if all page layers have frame loss within 1 second, the frame loss rate per second of standard two is counted as 1); if one page layer does not have frame loss within 1 second, the frame loss rate per second is counted accordingly at standard one, and the frame loss rate per second of standard two is also counted (for example, the frame loss rate per second of standard two is counted as 0). In this way, by synchronously counting standard one and standard two, the degree of judgment of the jamming phenomenon of the currently displayed page can be improved.

[0083] Step 103, based on the first parameter value and the first control strategy, determine that the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate, so that the display content of the output interface of the current application continues to be generated based on the second frame rate; the second frame rate is lower than the first frame rate; wherein the first control strategy is used to characterize that the display screen displays a freeze phenomenon in outputting the display content of the output interface of the current application.

[0084] In the present application, if the first parameter value obtained by the electronic device represents the duration of time taken by the display screen of the electronic device to lose N frames within a first time period in the process of generating the display content of the output interface of the current application at a first frame rate, then when obtaining the first parameter value, the electronic device may also compare the first parameter value with a first time threshold preset in the electronic device to determine whether the duration of time taken by the display screen to lose N frames within the first time period is less than the first time threshold, and obtain a judgment result. If the judgment result represents that the duration of time taken by the display screen to lose N frames within the first time period is less than the first time threshold, it is determined that a freeze occurs in the display content of the output interface of the current application displayed on the display screen of the electronic device, and the display screen of the electronic device is controlled to switch from the first refresh rate to the second refresh rate according to the first control strategy, so that the electronic device continues to generate the display content of the output interface of the current application based on the second frame rate; wherein the second refresh rate is lower than the first refresh rate, and the second frame rate is lower than the first frame rate.

[0085] Here, the first time threshold represents the corresponding time (for example, called badTimeThreshold) set when the display content of the output interface of the current application is stuck. The first control strategy represents that when the display screen of the electronic device displays the display content of the output interface of the current application and there is a stuck phenomenon, the display screen of the electronic device is controlled to switch from the first refresh rate to the second refresh rate. In this way, by controlling the display screen of the electronic device to switch from the first refresh rate to the second refresh rate when there is a stuck phenomenon in the display content of the display screen, it can be ensured that the display content of the current application can be smoothly output.

[0086] In the present application, in order to improve the judgment result of the stuttering phenomenon, when the electronic device determines that the time taken for the display screen to lose N frames in the first time period is less than the first time threshold, the electronic device can also calculate the time taken for the display screen to lose N frames in the second time period; wherein the second time period is equal to the length of the first time period, and the difference between the starting value of the second time period and the starting value of the first time period is M, and M is greater than or equal to 1; if the time taken for the display screen of the electronic device to lose N frames in the second time period is also less than the first time threshold, it is determined that the display content of the output interface of the current application displayed by the display screen has a stuttering phenomenon, and the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate.

[0087] For example, a first time threshold (badTimeThreshold) and a second time threshold (GoodTimeThreshold) are set in the electronic device, wherein the second time threshold (GoodTimeThreshold) may be 1s, and the first time threshold (badTimeThreshold) may be 300ms, that is, the second time threshold (GoodTimeThreshold) is greater than the first time threshold (badTimeThreshold). Assuming that the maximum frame rate supported by the display screen of the electronic device is 90fps, when the output interface of the current application of the electronic device runs at 90fps by default, the electronic device can calculate the time taken for the output interface to drop fixed frames (such as 7 frames) within a first time period (such as 5 seconds) in the process of generating the display content of the output interface of the current application based on 90fps. If the time taken is less than a first time threshold (badTimeThreshold), the refresh frequency of the display screen is not switched at this time, but monitoring is continued. If the time taken for the output interface to drop fixed frames (such as 7 frames) is less than the first time threshold for two or more consecutive time periods (for example, shifted by 150 milliseconds), it is considered that the output interface is not suitable for running at 90fps, and the display screen is controlled to switch from 90fps to 60fps.

[0088] Here, when monitoring whether the time taken by the output interface of the current application program to drop fixed frames (such as 7 frames) is less than the first time threshold in two or more consecutive time periods, it is not based on the first time period (such as 5 seconds) and monitored once every 5 seconds, but at a time interval of less than 5 seconds. The interval can be as small as possible (for example, it can be monitored once every 150 milliseconds of translation). Here, monitoring is performed with a 1-second interval as an example, such as monitoring once in the first time period (1-5 seconds), monitoring once in the second time period (2-6 seconds), and monitoring once in the third time period (3-7 seconds). If the monitoring results of several times all indicate that the time taken by the output interface of the current application program to drop fixed frames (such as 7 frames) is less than the first time threshold, it means that the current output interface is not suitable for running at 90fps, and the display screen is controlled to switch from 90fps to 60fps. In this way, repeated switching of the refresh frequency of the display screen can be avoided to improve the stability after the refresh frequency switching.

[0089] In another embodiment, if the first parameter value obtained by the electronic device represents the number of frames lost by the display screen of the electronic device in a first time period during the process of generating the display content of the output interface of the current application at a first frame rate. When obtaining the first parameter value, the electronic device can also compare the number of frames lost by the display screen in the first time period with a preset frame number threshold. If the comparison result represents that the number of frames lost by the display screen in the first time period reaches the frame number threshold, it is determined that the display screen displays the display content of the output interface of the current application and freezes, and the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate according to the first control strategy. In this way, it can be ensured that the display content of the current application can be output smoothly.

[0090] In the present application, in order to improve the stability of the display screen after switching the refresh rate, when the number of frame drops of the display screen in the first time period reaches the frame number threshold, the electronic device may not switch the refresh frequency of the display screen first, but continue to calculate the number of frame drops of the display screen in the second time period; wherein the second time period is equal to the length of the first time period, and the difference between the starting value of the second time period and the starting value of the first time period is M, and M is greater than or equal to 1; if the number of frame drops of the display screen in the second time period reaches the frame number threshold, it is determined that the display screen displays the output interface of the current application program and the display content is stuck, and then the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate according to the first control strategy. In this way, the accuracy and stability of switching the refresh frequency of the display screen can be improved.

[0091] Here, the first control strategy represents that when the display screen displays the content of the output interface of the current application program and freezes, the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate.

[0092] In the present application, if the first parameter value obtained by the electronic device represents the frame loss rate per second and the frame loss rate per N seconds of each page layer in the current application in the process of generating the display content of the output interface of the current application at the first frame rate, when the electronic device obtains the first parameter value, the electronic device can also determine whether each page layer has frame loss or part of the page layers have frame loss based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period. If frame loss occurs in each page layer, the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate by the first sub-strategy; if it is determined that at least one page layer has frame loss based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate by the second sub-strategy; wherein the priority of the first sub-strategy is higher than the priority of the second sub-strategy.

[0093] In the present application, the priority of the first sub-strategy is higher than the priority of the second sub-strategy means that: when each page layer of the electronic device has frame loss, and the frame loss rate is greater than the preset threshold, it means that the current system load is large. At this time, the electronic device can forcibly control the refresh rate of the display screen to switch from the first refresh rate to the second refresh rate. When the electronic device controls the refresh rate of the display screen to switch from the first refresh rate to the second refresh rate using the first sub-strategy, the electronic device will continue to monitor the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period until it is detected that each page layer has frame loss, and the frame loss rate is less than the preset threshold, and the display screen is controlled to switch from the second refresh rate to the first refresh rate using the first sub-strategy, and then the second sub-strategy is activated, and when the electronic device detects that at least one page layer of the current application has frame loss, the display screen is controlled to switch from the first refresh rate to the second refresh rate using the second sub-strategy.

[0094] Specifically, when the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate by the first sub-strategy, if the frame loss rate per second of each page layer at the second frame rate is less than the third frame rate threshold, and the frame loss rate per N seconds of each page layer at the second frame rate is less than the fourth frame rate threshold, the refresh rate of the display screen is controlled to switch from the second refresh rate to the first refresh rate, so that the electronic device can control the refresh rate of the display screen from the first refresh rate to the second refresh rate by the second sub-strategy when determining that at least one page layer has a frame loss phenomenon based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period; wherein the third frame rate threshold is less than the fourth frame rate threshold, and the third frame rate threshold and the fourth frame rate threshold are both set according to the second frame rate (such as based on 60fps). In this way, the switching speed of the refresh rate can be increased to reduce the system load, and the stability of the display screen after switching the refresh rate can be protected.

[0095] In the present application, the electronic device determines that frame loss occurs in each page layer based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period. The electronic device can also compare the frame loss rate per second of each page layer in the first time period with the first frame rate threshold, and compare the frame loss rate per N seconds of each page layer in the first time period with the second frame rate threshold to obtain a comparison result. If the comparison result indicates that the frame loss rate per second of each page layer in the first time period is greater than the first frame rate threshold, and the frame loss rate per N seconds of each page layer in the first time period is greater than the second frame rate threshold, then it is determined that the display content of the current display screen is stuck. At this time, the refresh rate of the display screen can be controlled to switch from the first refresh rate to the second refresh rate using the first sub-strategy; wherein the first frame rate threshold is less than the second frame rate threshold, and the first frame rate threshold and the second frame rate threshold are both set based on the first frame rate (such as 90fps as a benchmark).

[0096] Here, in order to ensure the stability of the refresh rate switching, the electronic device determines that each page layer has a frame loss phenomenon based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, and the frame loss rate per second of each page layer in the first time period is greater than the first frame rate threshold, and the frame loss rate per N seconds of each page layer in the first time period is greater than the second frame rate threshold. In this case, the frame loss of each page layer in the current application in the second time period (such as a 150 millisecond shift between the first time period) is further monitored to obtain the frame loss rate per second and the frame loss rate per N seconds of each page layer in the second time period, where N is greater than or equal to 2; if the frame loss rate per second of each page layer in the second time period is greater than the first frame rate threshold, and the frame loss rate per N seconds of each page layer in the second time period is greater than the second frame rate threshold, it is determined that the display interface of the current display screen has a freeze phenomenon, and the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate using the first sub-strategy; wherein the first time period is equal to the second time period, and the difference between the starting value of the first time period and the starting value of the second time period is M, and M is greater than or equal to 1. For example, the first time period is 1-5 seconds, the second time period is 2-6 seconds, and the first time period and the second time period are both 5 seconds long, but the first time period and the second time period are shifted at intervals of 1 second. In this way, the accuracy of the monitoring results can be improved by monitoring at smaller time intervals.

[0097] In the present application, when the electronic device controls the display screen to switch from a first refresh rate to a second refresh rate, the electronic device can also generate the display content of the output interface of the current application based on the second frame rate, and can also continue to monitor the frame loss of the electronic device in the process of generating the display content of the output interface of the current application based on the second frame rate, so as to obtain a second parameter value related to the frame loss; wherein the second parameter value can represent the number of frame losses of the display screen within a preset second time threshold in the process of the display screen of the electronic device generating the display content of the output interface of the current application based on the second frame rate, and the second time threshold can represent the corresponding time when the display screen displays the display content of the output interface of the current application without a freeze phenomenon; it can also represent the number of frames and the number of frame losses that meet the first frame rate requirement of the display screen within a first time period in the process of the display screen generating the display content of the output interface of the current application based on the second frame rate; it can also represent the frame loss rate per second and the frame loss rate per N seconds of at least one page layer or all page layers in the current application in the first time period in the process of the display screen generating the display content of the output interface of the current application based on the second frame rate. When the electronic device determines that the refresh rate of the display screen of the electronic device is switched from the second refresh rate to the first refresh rate based on the second parameter value and the second control strategy, the electronic device can continue to generate display content of the output interface of the current application based on the first frame rate.

[0098] Here, the second control strategy is used to indicate that the display screen of the electronic device displays the output interface of the current application program without any freeze.

[0099] Specifically, in the process of generating the display content of the output interface of the current application based on the second frame rate, the electronic device can also calculate the number of lost frames of the display screen within a second time threshold (GoodTimeThreshold); wherein the second time threshold represents the corresponding time preset when the display content of the output interface of the current application displayed on the display screen does not show any freeze phenomenon; if the number of lost frames of the display screen within the second time threshold is less than the first frame number threshold, it is determined that the display content of the output interface of the display screen does not show any freeze phenomenon, and at this time the refresh rate of the display screen can be controlled to switch from the second refresh rate to the first refresh rate according to the second control strategy.

[0100] Here, the second time threshold and the first frame number threshold are both related to the number of switching times of the refresh rate of the display screen.

[0101] For example, when the electronic device switches from the first refresh rate of 90fps to the second refresh rate of 60fps, if the number of frame drops of the display interface of the display screen does not exceed 7*(n+1) within the time of 2^n*GoodTimeThreshold (n=0,1,2,…), it will switch back to 90fps, where n is the time, and n increases with the number of times the display interface switches between 90fps / 60fps, and 2^n*GoodTimeThreshold will become longer. When n is 0, the square of n is 1, and 1 multiplied by the second time threshold GoodTimeThreshold (such as 1 second) is equal to 1 second, and as the number of switching increases, when n is 1, the square of n is 2, and 2 multiplied by the second time threshold GoodTimeThreshold (such as 1 second) is equal to 2 seconds, and so on.

[0102] The specific processing flow of this solution is as follows:

[0103] 1) Assume that the maximum frame rate supported by the display screen of the electronic device is 90fps, and the display interface of the display screen runs at 90fps by default;

[0104] 2) Calculate the time (e.g., 80 milliseconds) it takes for the display interface to drop fixed frames (e.g., 7 frames). If the time is less than the threshold badTimeThreshold (e.g., 300 milliseconds) and this happens in three consecutive time windows (the time windows are shifted by 150 ms), then the display interface is considered unsuitable for running at 90 fps and returns to 60 fps.

[0105] 3) After returning to 60fps, if the number of frame drops of the display interface does not exceed 7*(n+1) within 2^n*GoodTimeThreshold (n=0,1,2,…), it means that the number of frame drops of the current display content is small, then switch back to 90fps, and then loop through steps 2 to 3;

[0106] 4) When the refresh rate of the display interface of an application needs to be switched, reset it back to the default value of 90fps and repeat steps 1 to 3.

[0107] In the present application, in the process of generating the display content of the output interface of the current application based on the second frame rate, the electronic device can also calculate the number of frames and the number of lost frames that meet the first frame rate requirement in the first time period; if the number of frames that meet the first frame rate requirement in the first time period reaches the first frame number threshold, and the number of lost frames is less than the second frame number threshold, it is determined that the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate; or, if the number of frames that meet the first frame rate requirement in the first time period reaches the first frame number threshold, and the number of lost frames is less than the second frame number threshold, the number of frames and the number of lost frames that meet the first frame rate requirement in the second time period are calculated; if the number of frames that meet the first frame rate requirement in the second time period reaches the first frame number threshold, and the number of lost frames is less than the second frame number threshold, it is determined that the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate; wherein the second time period is equal to the first time period, and the difference between the starting value of the second time period and the starting value of the first time period is M, and M is greater than or equal to 1. For example, the first time period refers to 1-5 seconds, the second time period refers to 2-6 seconds, and so on. That is, the first time period and the second time period are shifted at a smaller time interval. In this way, the detection accuracy of the frame rate can be improved.

[0108] The specific processing flow of this solution is as follows:

[0109] 1) Assume that the maximum frame rate supported by the display screen of the electronic device is 90fps, and the display interface of the display screen runs at 90fps by default;

[0110] 2) Calculate the number of frame drops of the display within a certain time window (such as 300ms). If the number of frame drops exceeds a threshold (such as 7) and occurs in three consecutive windows (such as the window sliding with a translation of 150ms), it is considered that a freeze occurs, and the refresh rate of the display is controlled to switch from 90fps to 60fps.

[0111] 3) If after the display interface of the display screen is switched to 60fps, within a relatively long period of time (such as within 1s), the number of frames drawn within 11ms is 90% or more and there are few frame drops (such as less than 3 frames), and the conditions are met in 3 consecutive windows (such as the window sliding in 500ms), then it is considered that the display interface of the display screen can run at 90fps, and the refresh rate of the display screen is controlled to switch from 60fps to 90fps;

[0112] 4) When the refresh rate of the display interface of an application needs to be switched, reset it back to the default value of 90fps and repeat steps 1 to 3.

[0113] In the present application, the electronic device determines that at least one page layer has a frame loss phenomenon based on the frame loss rate per second and the frame loss rate per N seconds of each page layer in the first time period, and when the refresh rate of the display screen is controlled to switch from the first refresh rate to the second refresh rate by the second sub-strategy, the electronic device can also continue to monitor the frame loss rate per second and the frame loss rate per N seconds of each page layer at the second frame rate. When it is determined based on the monitoring results that not all page layers have a frame loss phenomenon, but only at least one page layer has a frame loss phenomenon at the second frame rate, the frame loss rate per second of the page layer where the frame loss occurs is compared with the fifth frame rate threshold, and the frame loss rate per N seconds of the page layer where the frame loss occurs is compared with the sixth frame rate threshold. If the comparison result indicates that the frame loss rate per second of at least one page layer at the second frame rate is less than the fifth frame rate threshold, and the frame loss rate per N seconds of at least one page layer at the second frame rate is less than the sixth frame rate threshold, it is determined that the display interface of the current display screen no longer freezes, and the refresh rate of the display screen can be controlled to switch from the second refresh rate to the first refresh rate.

[0114] The fifth frame rate threshold is smaller than the sixth frame rate threshold, and both the fifth frame rate threshold and the sixth frame rate threshold are set according to the second frame rate (eg, based on 60 fps).

[0115] The specific processing flow of this solution is as follows:

[0116] 1) Assume that the maximum frame rate supported by the display screen of the electronic device is 90fps, and the display interface of the display screen runs at 90fps by default;

[0117] 2) Assuming that the current application has 4 page layers, if the frame loss rate of at least one page layer per second in Standard 1 is greater than a certain frame rate threshold, it is considered that the running interface of the current display screen runs well at 90fps; if the frame loss rate of at least one page layer per second in Standard 1 is greater than a certain frame rate threshold (such as 15 frames) and the frame loss rate of at least one page layer every N seconds is greater than a certain frame rate threshold (such as 90 frames), it is considered that the running interface of the current display screen has a slight freeze. At this time, you can continue to observe (such as 10 seconds) and if the above situation still occurs, the current running interface of the control display screen is switched from 90Hz to 60Hz.

[0118] The frame rate thresholds here are all set based on 90fps. For example, the display can transmit 90 frames in 1 second, of which the time to transmit 1 frame is about 11 milliseconds, and setting 15 frames is 165 milliseconds.

[0119] 3) After the current running interface is switched from 90Hz to 60Hz, if the frame loss rate per second in standard one drops to a certain range (such as less than 5 frame loss rate per second), and the frame loss rate per N (such as every 10 seconds) in standard one is less than 30, it is considered that the stuttering phenomenon no longer occurs. At this time, the current running interface of the control display is switched from 60Hz to 90Hz.

[0120] 4) When the frame loss rate per second in standard 2 is greater than a certain threshold (such as 10 frames), and the frame loss rate per second in standard 2 meets the above conditions within 3 consecutive seconds, it is considered that the current system load is high, and the electronic device will force the refresh rate of the display screen to switch back from the default 90fps to 60fps, and ignore steps 2-3 until the frame loss rate per second in standard 2 drops below a certain threshold (such as 3 frames), and the frame loss rate per N seconds (such as 10 seconds) in standard 2 drops to a threshold (such as 20), then control the refresh rate of the display screen to switch from 60fps to 90fps. After the refresh rate of the display screen is switched from 60fps to 90fps according to the parameters in standard 2, check the parameters in standard 1, and repeat steps 2-3.

[0121] 5) When the refresh rate of the display interface of an application needs to be switched, reset it back to the default value of 90fps and repeat steps 1 to 4.

[0122] Here, in Standard 1, if at least one page layer has frame loss in different pulse signals within the same second, the number is counted according to the number of frame losses. For example, there are 4 layers in total, among which layer 1 loses 1 frame, layer 2 loses 1 frame, and layer 3 and layer 4 have no frame loss within the same second, then the number is 1 at the frame loss rate per second of Standard 1; if layer 1 loses 1 frame, layer 2 loses 3 frames, and layer 3 and layer 4 have no frame loss within the same second, then the number is 3 at the frame loss rate per second of Standard 1 (the maximum value of frame loss). Then, when the time condition of every N seconds is met, the sum of the number of frame losses per second in Standard 1 is used as the number of frame losses per N seconds in Standard 1.

[0123] In Standard 2, if at least one page layer has no frame loss in different pulse signals within the same second, the count is 0. For example, if layer 1 loses 1 frame, layer 2 does not lose frames, layer 3 loses frames, and layer 4 also loses frames, then it is recorded as 0 in Standard 2. If all page layers have frame loss in different pulse signals within the same second, the count is 1. For example, if layer 1 loses 1 frame, layer 2 loses 1 frame, layer 3 loses 1 frame, and layer 4 also loses 1 frame, then it is recorded as 1 in Standard 2. If all page layers have frame loss in different pulse signals within the same second, and layer 1 loses 1 frame, layer 2 loses 3 frames, layer 3 loses 1 frame, and layer 4 loses 2 frames, then it is recorded as 3 in Standard 2 (the maximum value of frame loss). Then, when the time condition of every N seconds is met, the sum of the number of frame losses per second in Standard 2 is used as the number of frame losses per N seconds in Standard 2.

[0124] In the present application, according to the satisfied criterion 2, in the process of controlling the refresh rate of the display screen from 90fps to 60fps with the first sub-strategy, only the number of frame losses per second is considered, and the frame loss rate every N (such as 10) seconds may not be considered. This is to achieve the switching as quickly as possible to speed up the switching efficiency of the refresh rate of the display screen.

[0125] However, according to the second criterion that is met, when the refresh rate of the display screen is switched from 60fps to 90fps using the first sub-strategy, both the frame loss rate per second and the frame loss rate per N seconds (such as 10 seconds) must be considered. This is to ensure the stability and accuracy of the refresh rate of the display screen after switching.

[0126] The present application monitors frame loss in the process of the display screen generating the display content of the output interface of the current application at the current frame rate. When it is determined that the display content of the current output interface is stuck, the refresh rate of the display screen is adaptively switched according to the stuck situation, thereby reducing the visual stuck phenomenon of the display screen to the user, and eliminating the need for the user to manually switch the frame rate and the tedious operation caused by the tedious operation.

[0127] Figure 2 The structure of the electronic device in this application is shown in FIG. Figure 1 , as shown in the figure, including:

[0128] A generating unit 201, configured to generate display content of an output interface of a current application based on a first frame rate if a display screen of the electronic device is at a first refresh rate;

[0129] A monitoring unit 202 is used to monitor frame loss in the process of generating display content of the output interface of the current application based on the first frame rate, and obtain a first parameter value related to the frame loss;

[0130] A determining unit 203 is configured to determine, based on the first parameter value and the first control strategy, that the refresh rate of the display screen is switched from the first refresh rate to a second refresh rate, so that display content of the output interface of the current application program continues to be generated based on the second frame rate; the second frame rate is lower than the first frame rate;

[0131] The first control strategy is used to indicate that a freeze occurs in the display content of the output interface of the current application displayed on the display screen.

[0132] In a preferred embodiment, the monitoring unit 202 is also used to monitor frame loss in the process of generating the display content of the output interface of the current application based on the second frame rate, obtain a second parameter value related to the frame loss; and trigger the determination unit 203 when the second parameter value related to the frame loss is obtained.

[0133] The determination unit 203 is also used to determine whether the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate based on the second parameter value and the second control strategy; the second control strategy is used to characterize that the display screen displays the output interface of the current application without any lag.

[0134] In a preferred embodiment, the monitoring unit 202 specifically calculates the duration of N frames lost in the first time period during the process of generating the display content of the output interface of the current application based on the first frame rate, and uses the duration of N frames lost in the first time period as the first parameter value. Wherein, N is greater than or equal to 2; the duration of N frames lost represents the total duration from the loss of the first frame to the end of N frames lost. Alternatively, the duration of N frames lost represents the total duration from the transmission of the first frame to the end of N frames lost. If the duration of N frames lost in the first time period is less than the first time threshold, the determination unit 203 is triggered to determine that the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate; the first time threshold represents the time corresponding to the freeze phenomenon of the display content of the output interface of the current application; or, if the duration of N frames lost in the first time period is less than the first time threshold, the monitoring unit 202 calculates the duration of N frames lost in the second time period; the second time period is equal to the length of the first time period, and the difference between the starting value of the second time period and the starting value of the first time period is M, and M is greater than or equal to 1; if the duration of N frames lost in the second time period is less than the first time threshold, the determination unit 203 is triggered to determine that the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate.

[0135] In a preferred solution, the monitoring unit 202 is specifically used to calculate the number of lost frames within a second time threshold in the process of generating the display content of the output interface of the current application based on the second frame rate; the second time threshold represents the time corresponding to when the display screen displays the display content of the output interface of the current application without freezing. If the number of lost frames is less than the first frame number threshold, the monitoring unit 202 triggers the determination unit 203 to determine that the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate; wherein the second time threshold and the first frame number threshold are both related to the number of times the refresh rate of the display screen is switched.

[0136] In a preferred embodiment, the monitoring unit 202 is further configured to calculate the number of lost frames in a first time period during the process of generating display content of an output interface of the current application based on the first frame rate; if the number of lost frames in the first time period reaches a frame number threshold, the monitoring unit 202 triggers the determination unit 203 to determine that the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate;

[0137] Alternatively, if the number of frame losses in the first time period reaches a frame number threshold, the monitoring unit 202 may further calculate the number of frame losses in a second time period; the second time period is equal to the first time period in length, and the difference between the starting value of the second time period and the starting value of the first time period is M, where M is greater than or equal to 1; if the number of frame losses in the second time period reaches the frame number threshold, the monitoring unit 202 triggers the determination unit 203 to determine that the refresh rate of the display screen is switched from the first refresh rate to the second refresh rate.

[0138] In a preferred embodiment, the monitoring unit 202 is further configured to calculate the number of frames and the number of lost frames that meet the first frame rate requirement within a first time period during the process of generating the display content of the output interface of the current application based on the second frame rate; if the number of frames that meet the first frame rate requirement within the first time period reaches a first frame number threshold, and the number of lost frames is less than a second frame number threshold, the monitoring unit 202 triggers the determining unit 201 to determine that the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate;

[0139] Alternatively, if the number of frames that meet the first frame rate requirement in the first time period reaches a first frame number threshold, and the number of lost frames is less than the second frame number threshold, the monitoring unit 202 calculates the number of frames and the number of lost frames that meet the first frame rate requirement in the second time period; if the number of frames that meet the first frame rate requirement in the second time period reaches a first frame number threshold, and the number of lost frames is less than the second frame number threshold, the monitoring unit 202 triggers the determination unit 201 to determine that the refresh rate of the display screen is switched from the second refresh rate to the first refresh rate; the second time period is equal to the first time period in length, and the difference between the starting value of the second time period and the starting value of the first time period is M, and M is greater than or equal to 1.
