Before describing embodiments of the present application in further detail, the terms and terminology involved in the embodiments of the present application will be described, and the terms and terminology involved in the embodiments of the present application are suitable for the following explanation.
The computer converts the shapes stored in memory into corresponding processes that are actually drawn on the screen, referred to as rendering.
When a frame is drawn, the display will send a vertical synchronization signal (Vertical Synchronization), VSync for short, before the next frame is ready to be drawn. The display is typically refreshed at a fixed frequency, which is the frequency at which the vertical synchronization signal is generated.
Android (Android) systems employ a UI architecture called a layer (Surface) to provide a user interface for applications. In an Android application, one or several windows are associated with each Activity (Activity) component, each window corresponding to a layer. With this layer, the application can render a User Interface (UI) of the window thereon. Finally, the drawn layers are uniformly submitted to a display subsystem (SurfaceFlinger) for composition, and finally displayed on a screen. Both the application program and the display subsystem can utilize hardware such as a GPU to perform UI rendering so as to obtain a smoother man-machine interaction interface.
The embodiment of the application provides an image processing method which can be executed by a processor of computer equipment. The computer device may be a device with image processing capability, such as a server, a notebook computer, a tablet computer, a desktop computer, a smart television, a set-top box, a mobile device (e.g., a mobile phone, a portable video player, a personal digital assistant, a dedicated messaging device, and a portable game device). Fig. 1 is an optional flowchart of an image processing method according to an embodiment of the present application, as shown in fig. 1, the method includes steps S110 to S140 as follows:
step S110, determining a target layer of the plurality of layers to be displayed.
Here, the target layer is associated with a touch event. The touch event may be a touch event of a user to the touch panel, or a pen writing event triggered by an electronic pen or a handwriting pen, which is not limited in the embodiment of the present application.
The target layer is a layer for displaying a target application program interface, wherein the touch event is triggered in the target application program, and the target application program is an application corresponding to the interface currently displayed by the display screen of the electronic device, and is usually a top-level application or a sub-top-level application.
Step S120, performing layer display processing on the target layer based on the first processing mode.
Here, a target layer in the plurality of layers may have a preset identifier, and in the layer display processing, the layer display processing is performed on the target layer by adopting a first processing manner.
Step S130, performing layer display processing on at least one non-target layer of the plurality of layers based on the second processing manner.
Here, the layer display processing performed by the first processing manner occupies a first time period, and the layer display processing performed by the second processing manner occupies a second time period, and the first time period is smaller than the second time period. That is, the display scheduling time is shortened for the target layer in the multiple layers, and the method can be specifically implemented to take corresponding jump logic in at least one transaction of calling the target layer to accelerate the layer display processing process of the target layer, for example, the method does not need to wait for the identification signal that the previous layer has been processed to be immediately scheduled at any scheduling time, or the transaction state of the target layer in the default cache queue is processed directly as a ready state.
It can be understood that the layer display processing procedure of the electronic device is as follows: the rendering thread is used for rendering one or more layers after the UI thread finishes drawing the one or more layers, and then synthesizing the layers by the synthesizing thread and displaying the synthesized layers on a display screen of the electronic device. Measurement, layout and drawing of each frame of layers and rendering are typically performed in response to a trigger of a first vertical synchronization signal, layer composition is performed in response to a second vertical synchronization signal, and a frame display refresh is performed in response to a third vertical synchronization signal. I.e. the time period required for the electronic device to render, render and synthesize the layer typically requires two synchronization periods. In this way, too long response delay of the electronic device to the touch event can be caused, and interaction smoothness of the electronic device is affected.
In the embodiment of the application, the target layer of the target application interface to be displayed is determined by adopting the touch event, and then the layer display processing is carried out by adopting a first processing mode and a second processing mode respectively for the target layer and the non-target layer in the multiple layers to be displayed, so that the display scheduling time of the target layer is flexibly adjusted, and further, the better optimization effect and the better delay experience of the display subsystem are realized.
In some embodiments, the step S110 "determining a target layer among the multiple layers to be displayed and processed" is further implemented to take, as the target layer, a layer corresponding to the target application when the touch event is received and the layer displayed in the current window is detected as the target application.
In the implementation, after the event information is written through driving, the input subsystem reports the touch event, and after the touch event is detected to report, whether the top layer or the sub-top layer application of the current window stack is a target application program is judged, the target layer is determined, and the function of the target layer is enabled. Therefore, the target layer to be optimally processed is accurately judged by adopting double conditions of the touch event and the target application program, and additional function enabling limitation is not needed.
In some embodiments, the method further comprises the following steps S140 to S160:
step S140, obtaining a time average value of the preset multi-frame image of the target layer for layer display processing.
Here, the layer display processing includes at least a rendering processing and a synthesizing processing, and the time average value of the layer display processing includes a rendering time-consuming average value and a synthesizing time-consuming average value.
The preset multi-frame image is the multi-frame image to be displayed and processed in a set statistical period, and the statistical period can be any time length of 1 second, 3 seconds, 5 seconds and the like. For example, the average rendering time consumption of the near 30 frames of the target layer application and the average synthesizing time consumption of the near 30 frames of the display subsystem are detected respectively, and then summed to determine the time average value of the layer display processing of the preset multi-frame image of the target layer.
Step S150, determining that the time average value exceeds one frame period.
It should be noted that, the UI framework periodically performs layer drawing and rendering based on the first vertical synchronization signal; the hardware synthesis HWC performs layer synthesis periodically based on the second vertical synchronization signal; the display screen is periodically refreshed with image frames based on the third vertical synchronization signal. One frame period represents, for example, a period between the second vertical synchronization signal and the third vertical synchronization signal.
In the case where the sum of the rendering time-consuming average value and the composition time-consuming average value exceeds one frame period, it is explained that the time spent on rendering the layer or the composition layer is long, and the operating frequency of the target processor needs to be raised.
In step S160, the operating frequency of the adjustment target processor is changed from the first frequency to the second frequency.
Here, the target processor may be a GPU or a CPU, and the first frequency is greater than the second frequency. In some embodiments, the working frequency of the target processor is the frequency of each core of the CPU, the second frequency is determined according to the maximum grade of the frequencies of the middle, large and small cores of the CPU, and the minimum frequency of the corresponding core of the CPU is set as the second frequency according to a preset percentage; in some embodiments, the current gear is reduced to the next gear if the first frequency is a minimum frequency of the current gear in the preset frequency map and the current gear is not the lowest gear.
It should be noted that the application App main thread starts to calculate display contents in the CPU, such as creation of views, layout calculation, picture decoding, text drawing, and the like. And then the CPU submits the calculated bitmap to the GPU, and the GPU obtains the bitmap and then transforms, synthesizes and renders the bitmap. The GPU then submits the rendering results to the frame buffer, waiting for the next time a vertical synchronization signal arrives for display on the screen. Therefore, by monitoring the system and the application and properly carrying out frequency change, the embodiment of the application can obtain better delay experience under the condition of smaller influence of power consumption.
In this way, the processing speed of the UI thread and the rendering thread can be improved by improving the working frequency of the target processor of the electronic device, so that the time spent on drawing and rendering the layer can be reduced, and the smoothness of layer display is improved.
In some implementations, the layer display processing includes rendering processing and composition processing; the layer display processing performed by the first processing mode occupies a first time period, and the layer display processing performed by the second processing mode occupies a second time period, which comprises the following steps: in the first processing mode, the rendering processing and the synthesizing processing aiming at the target layer occupy a first time period, and the first time period is less than or equal to one frame period; the rendering processing and the synthesizing processing aiming at the non-target layer occupy a second time period in the second processing mode; the second time period is greater than one frame period.
In this way, rendering and synthesizing are completed in one frame period for the target layer, and rendering and synthesizing are performed in more than one frame period for the non-target layer according to the conventional flow, so that delay can be reduced, and touch experience of the electronic device can be improved.
In some embodiments, the composition process includes a layer commit sub-phase, a control frame transfer sub-phase, a layer buffering sub-phase, and a composition preparation sub-phase, and the first processing manner includes at least one of the following manners such that the first time period is less than or equal to one frame period: in the layer submitting sub-stage, directly submitting the target layer before the delay signal of the previous layer of the target layer is not received; wherein the delay signal is used for indicating that the previous layer is processed; in the sub-stage of the control frame transmission, the target image layer is directly transmitted; setting the state of the target layer in a cache queue as a ready state in the layer cache sub-stage; the buffer queue is used for storing a layer to be processed with a preset frame period length; in the synthesis preparation sub-phase, a state setting is made for the target layer based solely on a first identification signal of a current frame, the first identification signal being used to indicate whether a buffer of the current frame is accessible.
Here, the layer submitting sub-stage is a stage of submitting the layer to the display synthesis subsystem, and the conventional flow is a delay signal to wait for the situation that the current fence of the previous layer is to be displayed immediately.
The control frame transmission sub-stage is to control the generation of the image layer to avoid the overflow of the downstream buffer when the upstream production speed is greater than the downstream consumption speed in the process of transmitting the data stream from the upstream producer to the downstream consumer.
The layer cache sub-stage is a cache queue in the scheduling framework, and the first processing mode of the embodiment of the application can select the state of the default target layer as the ready state so as to speed up scheduling, namely, release processing is performed on the transaction of the target layer, thereby reducing delay time.
The synthesis preparation sub-stage is to read the first identification signals of the previous frame before synthesizing a plurality of layers, and in the conventional process, the identification information of the previous two frames, such as the current fence (present fence) of the frame 0 and the frame 1, need to be read.
In this way, in the process of waiting for the release of the first identification signal from the previous frame in the scheduling process in the conventional process and in the process of the existence of the backpressure process or the state preparation, the direct call is realized by the jump logic or the default setting for the target layer, so that the synthesis processing process is accelerated, and the delay of the display subsystem is reduced.
In some embodiments, the second treatment regimen comprises at least one of the following: at the layer submitting sub-stage, submitting each non-target layer to a display subsystem after receiving the delay signal; in the control frame transmission sub-stage, controlling the transmission speed of each non-target image layer to a display subsystem; setting the state of each non-target layer in the cache queue as a waiting state in the layer cache sub-stage; in the synthesis preparation sub-stage, a state setting is performed for the non-target layer based on a first identification signal of a current frame and a first identification signal of a previous frame, where the first identification signal is used to indicate whether a buffer of the corresponding frame is accessible.
Here, the display subsystem (surfacefringer) is a core process of the display subsystem, and is mainly responsible for synthesizing all layers into a Framebuffer, and then a screen reads the Framebuffer and displays the Framebuffer to a user for viewing. Synthesizing layers to a screen
It will be appreciated that the identification signal is the current barrier released after the layer processing is completed, and is used to indicate that the current processing step of the corresponding layer has been completed, and it is necessary to detect whether the current barrier of the previous layer is available before processing the current layer, if so, the current processing step may use this current layer, and if not, it is necessary to wait until the current barrier of the previous layer becomes available.
In some embodiments, the target layer is provided with a preset identifier, and the method further includes: acquiring attribute information of each layer in the plurality of layers through a hardware combination abstract layer; wherein the attribute information comprises whether the preset identifier is set; in the second processing mode, aiming at the at least one non-target layer, responding to the received second identification signal, and displaying the at least one non-target layer after overlapping; wherein the second identification signal is used for indicating that the display of the previous frame of the at least one non-target layer is completed; and in the first processing mode, for the target layer, skipping waiting for the second identification signal, and directly overlapping with the at least one non-target layer for display.
In this way, the corresponding setting is performed after the preset identifier of the target layer is obtained in the hardware combination abstract layer, so that the target layer and the non-target layer are respectively overlapped and displayed by adopting a first processing mode and a second processing mode, and the performance optimization of the display stage is realized.
In some embodiments, the method further comprises: and in the process of synthesizing the layers to be displayed, deleting the preset identification of the target layer in response to detecting that the target layer is destroyed.
In this way, under the condition that the target layer is destroyed, a plurality of layers are synthesized according to the conventional flow, so that the operation complexity and the situation that program abnormality can occur are reduced.
The above image processing method is described below in connection with a specific embodiment, however, it should be noted that the specific embodiment is only for better illustrating the present application, and is not meant to be a undue limitation on the present application.
In order to solve the problem of poor delay experience of a display subsystem in a main scene process of drawing by using a handwriting pen on an android tablet, whether the android tablet is a target layer is judged by acquiring a top-layer application and a handwriting event, and aiming at the target layer, the target layer needs to enter a single frame function (single frame), which is equivalent to carrying out layer display processing on the target layer according to the first processing mode.
Fig. 2 is a schematic flow chart of a processor optimization strategy provided in the embodiment of the present application, as shown in fig. 2, after a program is started, step S21 of single-frame excitation is sequentially performed, that is, after a single-frame function is started, according to the rendering composite data of the previous frames is detected, a CPU frequency range is adjusted according to the rendering composite data in a full-frequency downshifting manner to perform frequency adjustment, so as to achieve the best effect and the lowest excitation (boost) frequency range. Step S22, detecting the state, namely detecting whether the actual rendering process and the synthesizing process can be completed in one synchronous period, if not, executing step S23 to perform excitation according to time, namely acquiring multi-frame rendering synthesized data in a fixed period to perform excitation adjustment on a CPU frequency range; if so, step 24 is performed to operate at the current frequency.
Here, the current frequency is the frequency of each core of the CPU, and the full-frequency downshift is to adjust the lowest frequency setting by percentage according to the maximum value of the large, medium and small core frequency table of the CPU, after which the minimum frequency of the CPU core is fixed to the set value.
In some implementations, the rendering of the inspection application is approximately 30 frames on average time consuming; checking the near 30 frame composition average time consumption of a display subsystem (surfacefringer, a display system service for defining-uniformly managing layers); then, according to the CPU frequency strategy adjustment of the corresponding gear which is time-consuming; if rendering and compositing can be completed within one frame period, no CPU stimulus is done.
Fig. 3 is a schematic flow chart of a cloud update list policy according to an embodiment of the present application, as shown in fig. 3, where the policy includes the following procedures: step S31, creating a layer; step S32, setting a transaction state; step S33, judging whether the current layer is a white list application; if the judgment result is that the flow is not the normal flow, executing the normal flow; if yes, executing step S34, and continuing to judge whether a writing event is received; if the pen writing event is received, continuing to execute the step S35, and enabling a single frame mark; otherwise, the conventional flow is executed.
It should be noted that, after the UI thread finishes the measurement layout drawing, the rendering thread executes the operation of creating the layer in step 31, and then the surface creator client executes the operation of setting the transaction state in step S32, and then sends the transaction state to the display subsystem for the subsequent synthesis process. And judging the pen writing event and the top layer of the current window in the display subsystem, and setting a single-frame mark enabling switch to open a single-frame function enabling switch when the pen writing event and the top layer of the current window meet the function opening condition. The white list is maintained in a cloud updating mode, the sub-threads are synchronized to the display subsystem through the first networking after the electronic equipment is started, the updating mode is simpler, and the updating can be performed without an OTA upgrading system.
In some embodiments, the composition process flow includes a layer commit sub-phase, a control frame transfer sub-phase, a layer cache sub-phase, and a composition preparation sub-phase. Fig. 4 is a logic flow chart of a single-frame performance optimization process according to an embodiment of the present application, as shown in fig. 4, including the following steps S41 to S48:
step S41, it is determined whether the single frame flag is enabled.
Here, if the single frame function is not enabled, i.e., the current layer is a non-target layer, a normal flow is performed; if the single frame function is enabled, i.e. the current layer is the target layer, the scheduler is executed in step S42.
It should be noted that when the single frame function is enabled, the fixed working time of the display subsystem is not set, so that the functions of the display subsystem become more flexible.
Step S42, scheduling program.
In step S43, immediate scheduling of frame processing is performed by the scheduler.
In step S44, in the layer submitting sub-stage, the target layer is submitted directly before the delay signal of the previous layer of the target layer is not received.
Here, in the android native mechanism, a 1ms delay signal is waited to cover the situation that the current fence is to be displayed immediately when the current fence is submitted (commit), and if the current fence is the target layer, no corresponding wait is performed, namely the target layer defaults to wait for the current fence in the process of submitting.
Notably, while the layer latches the buffer (latch buffer), the native logic will typically wait for the current barrier information for this layer, nor will it wait if the target layer.
In step S45, in the sub-stage of frame control transmission, the target layer is directly transmitted.
Here, for the non-target layer, a backpressure flow exists in the conventional flow, the backpressure function allows the GPU to control the frame of the production end, the flow of quick screen-up is not suitable for the scene of the control frame, if the flow is the target layer, the flow is skipped, and the embodiment of the application always displays and delivers for the target layer, so that the delay is shortened.
In step S46, in the layer cache sub-stage, the state of the target layer is set as the ready state in the cache queue.
The buffer queue is used for storing the to-be-processed layer with the preset frame period length, and the transaction state of the target layer is set as the ready state by default in the embodiment of the application, and can be directly called, namely, the transaction of the target layer is released to be processed and passed through in an accelerating way, so that the delay time is reduced.
In step S47, in the synthesis preparation sub-phase, a state setting is performed for the target layer based on only the first identification signal of the current frame.
Here, the first identification signal may be represented as a current fence (present fence), where the current fence of the current frame 0 and the current fence of the previous frame 1 are read according to conditions in the android native mechanism, and if the current fence is a single-frame scene, the current fence of the current frame 0 is directly taken to set the state of the target layer.
Step S48, synthesizing the layers.
It should be noted that, in the process of synthesizing the layers, if the target layer is destroyed, the single frame mark (corresponding to the preset mark) is removed as a non-target layer to be processed according to the conventional flow.
In some embodiments, after composition, at an overlay (overlay) module of the hardware composition abstraction layer, no waiting is performed on the current barrier for the target layer in the flow of waiting for the barrier time, thereby accelerating single frame layer screening.
Here, the overlay module overlays the layers synthesized by the GPU and the layers synthesized by the hardware abstraction layer through the overlay engine, when the layers are submitted to DRM for display, the overlay module needs to wait for the previous frame of each layer to display and release the current barrier and then start the mapping of the next frame, and if the layers are target layers, the current barrier is not directly mapped.
The image processing method provided by the embodiment of the application has at least the following beneficial effects: 1) By adopting corresponding jump logic for the target layer in the process of the security Zhuo Changgui, the processing process is accelerated to optimize the delay data, so that better optimization effect and more excellent delay experience can be obtained. 2) The intelligent frequency modulation function is used for monitoring the system and the application, and frequency change is properly carried out, so that the influence of power consumption is smaller when a single-frame function is realized. 3) By adopting the dual-condition judgment of the pen writing event and the top application, no additional function enabling limitation is carried out, so that the scene recognition is more accurate, and the optimized azimuth is wider. 4) The embodiment of the application adopts a cloud list updating mode, does not need to modify configuration files, has a simpler updating mode, and can update without an OTA upgrading system.
