Description

Technical Field

[0001] The present disclosure relates to the field of image processing technology, and in particular to a freeze detection method and device. Background Art

[0002] With the rapid development of terminals, users use terminals more and more frequently and for longer periods of time. When users use mobile terminals, the smoothness of image processing is one of the most direct and important factors affecting users' evaluation of terminal performance. Therefore, terminal freeze detection is of great practical significance for improving user experience.

[0003] In the related art, it is possible to determine whether the terminal is stuck by detecting whether the time consumed by the central processing unit (CPU) exceeds the time consumption threshold. Since the corresponding processing modules in image imaging include CPU, graphics processing unit (GPU) and view controller. When the processing time of any image frame in the CPU or GPU is too long, the data corresponding to the next image frame is not ready, and the terminal display interface still displays the previous image frame, causing the image processing process to be stuck. Therefore, only detecting whether the CPU is stuck will lead to inaccurate detection of stuck during image processing. Summary of the invention

[0059] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0061] With the development of science and technology, the terminal technology has become increasingly mature, which has improved the convenience of users' production and life. When users operate the terminal, the display interface of the terminal needs to be imaged on the screen. Figure 1 FIG. 1 is a schematic diagram of a terminal framework of a method for detecting a jamming according to an exemplary embodiment. Figure 1 As shown, the terminal 1 includes a central processing unit 11 (CPU), a graphics processing unit 12 (GPU) and a view controller 13. During the screen imaging process of the terminal 1, first, the central processing unit 11 calculates the view to be displayed and the corresponding display mode; secondly, the graphics processor 12 renders the view to be displayed into a bitmap and then stores it in the frame buffer; finally, the view controller 13 reads the content of the frame buffer according to the frequency, and displays the view to be displayed on the display interface of the terminal according to the corresponding display mode.

[0062] In some embodiments, when the CPU or GPU processing time of a frame of data exceeds the processing threshold, resulting in the next frame of data not being ready, so that the terminal is still displaying the image of the previous frame, frame loss will occur. If the frame loss time is too long, the terminal's display interface will be stuck, and the user experience will be reduced. Therefore, terminal jam detection is of great practical significance for developers to optimize terminal performance and improve user experience.

[0063] According to some embodiments, Figure 2 FIG. 1 is a background diagram of a jamming detection method according to an exemplary embodiment. Figure 2As shown, during the screen imaging process of the terminal, the terminal monitors the time consumed by the event processing runloop when the CPU calculates the view to be displayed and the corresponding display mode. When the terminal detects that the time consumed by the runloop exceeds the time consumption threshold, it is determined that the terminal is stuck.

[0064] In some embodiments, there is no detection scheme for whether the GPU is stuck. Therefore, when the GPU is stuck during rendering and the CPU processing time does not exceed the threshold, only monitoring the time of the runloop cycle cannot detect the stuck situation caused by the terminal image processing process, thereby affecting the user experience.

[0065] According to some embodiments, Figure 3 FIG. 1 is a schematic diagram of a method for detecting a jamming according to an exemplary embodiment. Figure 3 As shown, the terminal 110 can determine whether the terminal 110 has a jam by monitoring the time taken by the CPU to process each runloop cycle. When the terminal 110 determines that the terminal 110 has a jam, the terminal 110 can upload the jam information to the server 130 through the network 120. When the server 130 receives the jam information, the server 130 can collect statistics on the jam information. The user can optimize the terminal based on the statistical jam information, thereby improving the user experience.

[0066] It is easy to understand that the terminal includes but is not limited to: wearable devices, handheld devices, personal computers, tablet computers, vehicle-mounted devices, smart phones, computing devices or other processing devices connected to wireless modems, etc. In different networks, terminal devices can be called different names, such as: user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, cellular phone, cordless phone, personal digital assistant (PDA), terminal devices in the fifth generation mobile communication technology (5th generation mobile networks, 5G) network or future evolution network, etc. The live broadcast terminal can be installed with an operating system, which refers to an operating system that can be run in the terminal, a program that manages and controls terminal hardware and terminal applications, and is an indispensable system application in the terminal. The operating system can be an IOS system.

[0067] According to some embodiments, the terminal 110 may be connected to the server 130 via a network 120. The network 120 is used to provide a communication link between the terminal 110 and the server 130. The network 120 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc. It should be understood that Figure 2 The number of terminals 110, networks 120, and servers 130 is only illustrative. Any number of terminals, networks, and servers may be provided according to actual needs. For example, server 130 may be a server cluster composed of multiple servers. A user may use terminal 110 to interact with server 130 through network 120 to perform freeze detection, etc.

[0068] Figure 4 is a flow chart of a jam detection method according to an exemplary embodiment. Figure 4 As shown, the jam detection method can be applied to an image processing scenario, for example. The method can be implemented by a computer program and can be run on a terminal including an image display function, including the following steps:

[0069] In step S11, if it is detected that the central processor obtains display information for the image, the time-consuming detection subthread of the graphics processor is triggered;

[0070] According to some embodiments, the execution subject of the embodiment of the present disclosure may be a terminal, and the operating system included in the terminal may be an IOS system. The central processing unit (CPU) is the computing and control core of the computer system and is the final execution unit for information processing and program running. The CPU of the embodiment of the present disclosure may be a processor in a terminal. The CPU may be used to calculate the displayed view and specific display information. The CPU does not specifically refer to a fixed CPU. For example, when the CPU identifier changes, the CPU will also change accordingly.

[0071] In some embodiments, the image may be a single image or an image in a set of images. An image set refers to a group of at least one image. The image set does not specifically refer to a fixed set. For example, when the number of images included in the image set changes, the image set may also change accordingly. For example, when the images included in the image set change, the image may also change accordingly.

[0072] According to some embodiments, the image does not specifically refer to a fixed image. For example, when the image content of the image changes, the image may also change accordingly. For example, when the image identifier of the image changes, the image may also change accordingly.

[0073] It is easy to understand that the display information refers to the display information corresponding to the image determined by the CPU, including but not limited to the image view information of the displayed image, the display method of the image, the display position of the image, etc.

[0074] Optionally, a graphics processing unit (GPU), also known as a display core, visual processor, or display chip, is a microprocessor that is specifically used to perform image and graphics related operations on personal computers, workstations, game consoles, and some mobile devices (such as tablets, smart phones, etc.). The GPU of the disclosed embodiment refers to a microprocessor that renders the view information to be displayed into a bitmap and then stores the frame buffer. The GPU does not specifically refer to a fixed GPU. For example, when the GPU identifier changes, the GPU will also change accordingly.

[0075] In some embodiments, a thread is the smallest unit that the operating system can schedule operations on. A thread refers to a single sequential control flow in a process. A process can have many threads, and each thread executes different tasks in parallel. For example, an image processing process may include a GPU image processing thread and a CPU image processing thread. The GPU image processing thread is used to render the view to be displayed into a bitmap and then store it in the frame buffer. The CPU image processing thread is used to calculate the view to be displayed and the corresponding display method.

[0076] It is easy to understand that the time-consuming detection sub-thread refers to the sub-thread added to the GPU image processing thread during the image processing process and is responsible for monitoring the GPU time consumption. In other words, the time-consuming detection sub-thread does not affect the operation of the GPU image processing thread during the image processing process. The time-consuming detection sub-thread is only used to obtain the time spent by the GPU during the rendering process of a certain image. The time-consuming detection sub-thread can be a thread that is executed concurrently with the GPU image processing thread during the image processing process. The time-consuming detection sub-thread does not specifically refer to a fixed sub-thread. For example, when a modification instruction for the time-consuming detection sub-thread is received, the time-consuming detection sub-thread may also change accordingly.

[0077] According to some embodiments, when the terminal executes the jam detection method, if it is detected that the central processing unit obtains display information for an image, a time-consuming detection sub-thread that can trigger a graphics processor is performed.

[0078] In step S12, a time-consuming detection subthread is used to obtain a first processing duration corresponding to the image;

[0079] According to some embodiments, the first processing duration is the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image. The first processing duration does not specifically refer to a fixed duration. For example, when the graphics processor is in a stuck state, the first processing duration may also change accordingly. For example, when the rendering speed of the graphics processor changes, the first processing duration may also change accordingly.

[0080] In some embodiments, when the terminal executes the jam detection method, if it is detected that the central processor obtains display information for the image, then the time-consuming detection subthread that can trigger the graphics processor is detected. The terminal can use the time-consuming detection subthread to obtain the first processing duration corresponding to the image. For example, the terminal can use the time-consuming detection subthread to obtain the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image, that is, the terminal can obtain the duration between the start of rendering the image and the completion of rendering the image.

[0081] In step S13, if the first processing time is greater than or equal to the first time threshold, it is determined that the GPU freeze detection result is that the GPU is in a freeze state.

[0082] According to some embodiments, when the terminal executes the jam detection method, if it is detected that the central processing unit obtains the display information for the image, a time-consuming detection sub-thread is detected for triggering the graphics processor. The terminal can use the time-consuming detection sub-thread to obtain the first processing duration corresponding to the image. For example, the terminal can use the time-consuming detection sub-thread to obtain the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image, that is, the terminal can obtain the duration between the start of rendering the image and the completion of rendering the image. When the terminal obtains the first processing duration, if the first processing duration is greater than or equal to the first duration threshold, the terminal can determine that the jam detection result of the graphics processor is that the graphics processor is in a jammed state.

[0083] In some or related embodiments, if it is detected that the central processing unit obtains display information for an image, the time-consuming detection sub-thread of the graphics processor is triggered, and the time-consuming detection sub-thread is used to obtain the first processing duration corresponding to the image in the image set corresponding to the image, and the first processing duration is the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image. If the first processing duration is greater than or equal to the first duration threshold, the stuttering detection result of the graphics processor is determined to be that the graphics processor is in a stuttering state. Therefore, the first processing duration can be obtained through the time-consuming detection sub-thread, and whether the graphics processor is stuttered can be determined based on the duration. This can improve the situation where only the CPU can be determined to be stuttered when stuttering occurs during image processing, and can reduce the situation where only detecting whether the CPU is stuttered leads to inaccurate stuttering detection during image processing, can improve the accuracy of stuttering detection, and can improve the user experience.

[0084] Figure 5 FIG. 1 is a flow chart of a jam detection method according to an exemplary embodiment. Figure 5 As shown, the jam detection method includes the following steps:

[0085] In step S21, if it is detected that the central processor obtains display information for the image, the time-consuming detection sub-thread of the graphics processor is triggered;

[0086] The specific process is as described above and will not be repeated here.

[0087] In some embodiments, Figure 6 FIG. 1 is a timing diagram of a jam detection method according to an exemplary embodiment. Figure 6 As shown, the terminal can use the runloop to detect whether the CPU is in a stuck state. When the terminal detects that the central processor obtains the display information for the image, the terminal can trigger the time-consuming detection sub-thread of the graphics processor.

[0088] According to some embodiments, the terminal controls the central processor to obtain display information for the image, for example, the display position of the image and the display view information.

[0089] In step S22, if it is determined to perform frame callback processing on the image, the drawing start time point corresponding to the image is obtained;

[0090] According to some embodiments, the drawing start time point refers to the time point when the GPU starts rendering the image. The drawing start time point does not specifically refer to a fixed time point. The drawing start time point can be, for example, starting from zero, or the current time point when the image starts drawing. For example, the drawing start time point can be the current time point when the image starts drawing. When the time point when the CPU obtains the display information for the image changes, the drawing start time point can also change accordingly.

[0091] In some embodiments, when the terminal detects that the central processor obtains display information for an image and triggers the time-consuming detection subthread of the graphics processor, if it is determined to perform frame callback processing on the image, the terminal can obtain the drawing start time point corresponding to the image.

[0092] It is easy to understand that the terminal obtains the drawing start time point corresponding to the image, for example, which can be 1.20 seconds at 13:25 on January 5, 2020.

[0093] In step S23, a blank image view corresponding to the image is added, and blank image view addition completion information is sent to the time-consuming detection sub-thread;

[0094] According to some embodiments, a blank image view refers to a simple view added to determine whether the GPU is stuck. A blank view does not specifically refer to a fixed view. An image view refers to a view or a control for displaying an image. When the rendering information of the terminal for the image changes, the blank image view may also change accordingly.

[0095] According to some embodiments, the blank image view addition completion information is used to indicate that the addition of the blank image view has been completed. When the terminal determines to perform frame callback processing on the image, the terminal can obtain the drawing start time point corresponding to the image. The terminal can add a blank image view corresponding to the image and send the blank image view addition completion information to the time-consuming detection subthread.

[0096] In step S24, if it is determined that the triggering graphics processor has completed rendering of the image view of the image, a time-consuming detection subthread is used to obtain a rendering completion time point corresponding to the image;

[0097] According to some embodiments, when the terminal adds a blank image view corresponding to an image, the terminal can control the GPU to render all views corresponding to the image on the blank image view. In other words, when the terminal determines that the triggering graphics processor has completed rendering of the image view for the image, the terminal can use a time-consuming detection subthread to obtain the rendering completion time point corresponding to the image.

[0098] In some embodiments, the terminal uses a time-consuming detection sub-thread to obtain the rendering completion time point corresponding to the image, for example, which can be 1.29 seconds at 13:25 on January 5, 2020.

[0099] In step S25, the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image is determined as the first processing duration corresponding to the image;

[0100] The specific process is as described above and will not be repeated here.

[0101] According to some embodiments, the first processing duration is the duration between a drawing start time point corresponding to the image and a rendering completion time point corresponding to the image.

[0102] In some embodiments, if it is determined to perform frame callback processing on the image, the terminal can obtain the drawing start time point corresponding to the image. If it is determined that the triggering graphics processor completes the image view rendering of the image, the time-consuming detection subthread is used to obtain the rendering completion time point corresponding to the image. The terminal can determine the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image as the first processing duration corresponding to the image.

[0103] In some embodiments, the terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses the time-consuming detection subthread to obtain the rendering completion time point corresponding to the image, for example, which may be 1.29 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image as the first processing duration corresponding to the image, for example, which may be 0.09 seconds.

[0104] In step S26, if the first processing time is greater than or equal to the first time threshold, it is determined that the GPU freeze detection result is that the GPU is in a freeze state.

[0105] According to some embodiments, when the terminal obtains the first processing duration, the terminal may determine the jam detection result of the graphics processor based on the first processing duration, specifically, if the first processing duration is greater than or equal to the first duration threshold, the terminal may determine that the jam detection result of the graphics processor is that the graphics processor is in a jam state. If the first processing duration is less than the first duration threshold, the terminal may determine that the jam detection result of the graphics processor is that the graphics processor is not in a jam state.

[0106] In some embodiments, the first duration threshold refers to a threshold for detecting whether the graphics processor is stuck based on the first processing duration. The first duration threshold does not specifically refer to a fixed duration threshold. For example, when the terminal obtains a modification instruction for the first duration threshold, the terminal can modify the first duration threshold based on the modification instruction.

[0107] According to some embodiments, the first duration threshold may be, for example, 0.08s. The terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses a time-consuming detection subthread to obtain the rendering completion time point corresponding to the image, for example, which may be 1.29 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image as the first processing duration corresponding to the image, which may be, for example, 0.09 seconds. When the terminal determines that the first processing duration of 0.09 seconds is greater than the first duration threshold of 0.08 seconds, the terminal may determine that the freeze detection result of the graphics processor is that the graphics processor is in a freeze state.

[0108] In some embodiments, the first duration threshold may be, for example, 0.08s. The terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses a time-consuming detection subthread to obtain the rendering completion time point corresponding to the image, for example, which may be 1.25 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image as the first processing duration corresponding to the image, which may be, for example, 0.09 seconds. When the terminal determines that the first processing duration of 0.05 seconds is less than the first duration threshold of 0.08 seconds, the terminal can determine that the freeze detection result of the graphics processor is that the graphics processor is not in a freeze state.

[0109] In some embodiments, when the terminal determines the first duration threshold, the terminal can obtain the sub-duration of processing an image view when the graphics processor is not in a stuck state, obtain the target duration corresponding to a preset number of sub-durations, and determine the target duration as the first duration threshold, which can improve the accuracy of the duration threshold setting, improve the accuracy of determining the graphics processor stuck detection results, and improve the user experience.

[0110] According to some embodiments, when the terminal determines the first duration threshold, the terminal may obtain a sub-duration for processing an image view when the graphics processor is not in a stuck state, and the sub-duration obtained by the terminal may be, for example, 16ms. The terminal obtains a target duration of 80ms corresponding to a preset number of 5 sub-durations of 16ms, and determines the target duration of 80ms as the first duration threshold.

[0111] According to some embodiments, when the first processing duration is greater than or equal to the first duration threshold, the terminal determines that the GPU freeze detection result is that the GPU is in a freeze state, and the terminal can display the freeze detection result through a display interface. Figure 7 shown.

[0112] In some or related embodiments, if it is detected that the central processing unit obtains display information for an image, the time-consuming detection subthread of the graphics processor is triggered. If it is determined that the image is to be processed with a frame callback, the drawing start time point corresponding to the image is obtained, a blank image view corresponding to the image is added, and the blank image view addition completion information is sent to the time-consuming detection subthread. If it is determined that the triggering of the graphics processor to render the image view of the image is completed, the time-consuming detection subthread is used to obtain the rendering completion time point corresponding to the image. The duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image can be determined as the first processing duration corresponding to the image, which can improve the accuracy of obtaining the first processing duration, and can improve the accuracy of determining the jam detection result. In addition, if the first processing duration is greater than or equal to the first duration threshold, the jam detection result of the graphics processor is determined to be that the graphics processor is in a jammed state, reducing the situation where only detecting whether the CPU is jammed leads to inaccurate jam detection during image processing. The jam detection result can be obtained based on the first duration threshold, which can improve the accuracy of obtaining the detection result.

[0113] Figure 8 is a flow chart of a jam detection method according to an exemplary embodiment. Figure 8 As shown, the jam detection method includes the following steps:

[0114] In step S31, if it is detected that the central processor obtains display information for the image, the time-consuming detection sub-thread of the graphics processor is triggered;

[0115] The specific process is as described above and will not be repeated here.

[0116] In step S32, a time-consuming detection subthread is used to obtain a second processing time corresponding to the image;

[0117] According to some embodiments, the second processing duration is the duration between the drawing start time point corresponding to the image and the rendering time point of the currently rendered image view, and the currently rendered image view is the currently rendered image view among all image views corresponding to the image. The second processing duration does not specifically refer to a fixed duration. For example, when the current rendering view changes, the second processing duration may also change accordingly. For example, when the drawing start time point corresponding to the image changes, the second processing duration may also change accordingly.

[0118] In some embodiments, the terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses the time-consuming detection subthread to obtain the current rendering image view time point, for example, which may be 1.29 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering time point of the current rendering image view as the first processing duration corresponding to the image, for example, which may be 0.09 seconds.

[0119] In step S33, if the second processing time reaches the second time threshold, and it is determined that all image views corresponding to the image have not been rendered, then it is determined that the graphics processor freeze detection result is that the graphics processor is in a freeze state;

[0120] According to some embodiments, when the terminal obtains the second processing duration, the terminal may determine a jam detection result of the graphics processor based on the second processing duration.

[0121] According to some embodiments, if the second processing duration reaches the second duration threshold and it is determined that all image views corresponding to the image have not been rendered, the terminal can determine that the graphics processor's jam detection result is that the graphics processor is in a jammed state.

[0122] According to some embodiments, when the terminal obtains the second processing duration, the terminal can determine the jam detection result of the graphics processor based on the second processing duration. Specifically, if the second processing duration is greater than or equal to the second duration threshold, and it is determined that all image views corresponding to the image have not been rendered, the terminal can determine that the jam detection result of the graphics processor is that the graphics processor is in a jammed state. If the second processing duration is less than the second duration threshold, and it is determined that all image views corresponding to the image have been rendered, the terminal can determine that the jam detection result of the graphics processor is that the graphics processor is not in a jammed state.

[0123] In some embodiments, the second duration threshold refers to a threshold for detecting whether the graphics processor is stuck based on the second processing duration. The second duration threshold does not specifically refer to a fixed duration threshold. For example, when the terminal obtains a modification instruction for the second duration threshold, the terminal can modify the second duration threshold based on the modification instruction.

[0124] According to some embodiments, the terminal determines that all image views corresponding to the image have not been rendered, for example, the terminal may obtain the view number of the current rendered view, and determine whether all image views corresponding to the image have been rendered based on the view number. If the view number indicates that the current view is not the last image view, the terminal may determine that all image views corresponding to the image have not been rendered.

[0125] In some embodiments, the second duration threshold may be, for example, 0.1s. In some embodiments, the terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses a time-consuming detection sub-thread to obtain the current rendering image view time point, for example, which may be 1.31 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering time point of the current rendering image view as the first processing duration corresponding to the image, for example, which may be 1.01 seconds. When the terminal determines that the second processing duration of 1.01 seconds is greater than the second duration threshold of 0.1 seconds, and determines that all image views corresponding to the image have not been rendered, the terminal can determine that the freeze detection result of the graphics processor is that the graphics processor is in a freeze state.

[0126] In some embodiments, the second duration threshold may be, for example, 0.1s. In some embodiments, the terminal obtains the drawing start time point corresponding to the image, for example, which may be 1.20 seconds at 13:25 on January 5, 2020. The terminal uses a time-consuming detection sub-thread to obtain the current rendering image view time point, for example, which may be 1.22 seconds at 13:25 on January 5, 2020. The terminal determines the duration between the drawing start time point corresponding to the image and the rendering time point of the current rendering image view as the first processing duration corresponding to the image, for example, which may be 0.02 seconds. When the terminal determines that the second processing duration of 0.02 seconds is less than the second duration threshold of 0.1 seconds, and determines that all image views corresponding to the image are rendered, the terminal can determine that the freeze detection result of the graphics processor is that the graphics processor is not in a freeze state.

[0127] In some embodiments, when the terminal determines the second duration threshold, the terminal can obtain the sub-duration of processing an image view when the graphics processor is not in a stuck state, obtain the target duration corresponding to a preset number of sub-durations, and determine the target duration as the second duration threshold, which can improve the accuracy of setting the second duration threshold, improve the accuracy of determining the graphics processor stuck detection results, and improve the user experience.

[0128] According to some embodiments, when the terminal determines the second duration threshold, the terminal may obtain a sub-duration for processing an image view when the graphics processor is not in a stuck state, and the sub-duration obtained by the terminal may be, for example, 16ms. The terminal obtains a preset number of 5 sub-durations of 16ms corresponding to a target duration of 80ms, and determines the target duration of 80ms as the second duration threshold.

[0129] In step S34, if it is determined that the graphics processor is in a stuck state, the rendering quantity corresponding to at least one image view rendered at the same time in the graphics processor is adjusted.

[0130] According to some embodiments, when the terminal determines that the graphics processor is in a stuck state, the terminal may adjust the rendering quantity corresponding to at least one image view rendered in the graphics processor at the same time.

[0131] In some embodiments, the number of renderings corresponding to at least one image view rendered by the terminal at the same time may be, for example, 5. When the terminal determines that the graphics processor is in a stuck state, the terminal may adjust the number of renderings corresponding to at least one image view rendered by the graphics processor at the same time from 5 to 3.

[0132] In some or related embodiments, if it is detected that the central processing unit obtains display information for an image, the time-consuming detection subthread of the graphics processor is triggered, and the time-consuming detection subthread is used to obtain the second processing time corresponding to the image. Based on the second processing time, the freeze detection result of the graphics processor is determined. Since the second processing time is the time between the drawing start time point corresponding to the image and the rendering time point of the current rendered image view, it is possible to directly determine whether the graphics processor is frozen based on the rendering time point of the current rendered image view, which can reduce the waiting time until all views are rendered, reduce the time to obtain the freeze detection result, and improve the efficiency of freeze detection. Secondly, if it is determined that the graphics processor is in a frozen state, the number of renderings corresponding to at least one image view rendered at the same time in the graphics processor is adjusted, which can reduce the number of image views rendered by the graphics processor at the same time, reduce the freeze situation of the graphics processor, and reduce the situation where only detecting whether the CPU is frozen leads to inaccurate freeze detection during image processing, improve the efficiency of image processing, and improve the user experience.

[0135] The duration acquisition unit 902 is used to acquire a first processing duration corresponding to the image by using a time-consuming detection subthread, where the first processing duration is the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image;

[0136] The result determination unit 903 is used to determine that the GPU jam detection result is that the GPU is in a jam state if the first processing duration is greater than or equal to a first duration threshold.

[0137] According to some embodiments, Fig.10 is a block diagram of a jam detection device according to an exemplary embodiment. Fig.10 As shown, the duration acquisition unit 902 includes a time point acquisition subunit 912, a view adding subunit 922 and a duration acquisition subunit 932. The duration acquisition unit 902 is used to use a time-consuming detection subthread to acquire a first processing duration corresponding to the image, including:

[0138] The time point acquisition subunit 912 is used to acquire the drawing start time point corresponding to the image if it is determined to perform frame callback processing on the image;

[0139] The view adding sub-unit 922 is used to add a blank image view corresponding to the image, and send blank image view adding completion information to the time-consuming detection sub-thread;

[0140] The time point acquisition subunit 912 is further used to use the time-consuming detection subthread to acquire the rendering completion time point corresponding to the image if it is determined that the triggering graphics processor has completed rendering of the image view for the image;

[0141] The duration acquisition subunit 932 is used to determine the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image as the first processing duration corresponding to the image.

[0142] According to some embodiments, the duration acquisition unit 902 is further used to trigger the time-consuming detection sub-thread of the graphics processor, and then use the time-consuming detection sub-thread to acquire a second processing duration corresponding to the image, where the second processing duration is the duration between the drawing start time point corresponding to the image and the rendering time point of the currently rendered image view, and the currently rendered image view is an image view among all image views corresponding to the image;

[0143] The result determination unit 903 is further used to determine that the graphics processor's jam detection result is that the graphics processor is in a jammed state if the second processing duration reaches a second duration threshold and it is determined that all image views corresponding to the image have not been rendered.

[0144] According to some embodiments, Fig.11 is a block diagram of a jam detection device according to an exemplary embodiment. Fig.11 As shown, the device 900 further includes a threshold setting unit 904, which is used to obtain a sub-duration of processing an image view when the graphics processor is not in a stuck state;

[0145] A target duration corresponding to a preset number of sub-durations is obtained, and the target duration is determined as a duration threshold.

[0146] According to some embodiments, Fig.12 is a block diagram of a jam detection device according to an exemplary embodiment. Fig.12 As shown, the device 900 further includes a quantity adjustment unit 905, which is used to adjust the rendering quantity corresponding to at least one image view rendered in the graphics processor at the same time if it is determined that the graphics processor is in a stuck state.

[0147] In some or related embodiments, if the sub-thread triggering unit detects that the central processing unit has obtained display information for the image, the time-consuming detection sub-thread of the graphics processor is triggered, and the duration acquisition unit can use the time-consuming detection sub-thread to obtain the first processing duration corresponding to the image, and the first processing duration is the duration between the drawing start time point corresponding to the image and the rendering completion time point corresponding to the image. The result determination unit can determine that the stuttering detection result of the graphics processor is that the graphics processor is in a stuttering state if the first processing duration is greater than or equal to the first duration threshold. Therefore, the first processing duration can be obtained through the time-consuming detection sub-thread, and whether the graphics processor is stuttered can be determined based on the duration. This can improve the situation where only the CPU can be determined to be stuttered when stuttering occurs during image processing, and reduce the situation where only detecting whether the CPU is stuttered leads to inaccurate stuttering detection during image processing, which can improve the accuracy of stuttering detection and improve the user experience.
