The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the electronic device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

The problem of homogenization and flattening of visual effects of User Experience (UX) and User Interface (UI) of electronic equipment of an Android system exists. In order to enrich visual display effects, highlight operation elements and increase interface layering, the electronic equipment enables special effects such as blurring effects in some scenes. For example, aiming at some scenes with cross windows and changeable fuzzy backgrounds, the electronic equipment adopts a real-time fuzzy algorithm, a fuzzy layer is created in the synthesis stage of the Android display flow, the background corresponding to the fuzzy area is removed as a data source, and the Gaussian fuzzy algorithm is used for fuzzy processing.

However, since DPU synthesis does not support special effects processing, special effects processing can only be performed by the GPU, the real-time blurring algorithm is intended to take effect, and the electronic device must force the GPU synthesis as shown in fig. 3. In fig. 3, N represents an nth frame image, n+1 represents an n+1st frame image, n+2 represents an n+2nd frame image, and n+3 represents an n+3 rd frame image. Because the GPU synthesis load is high, power consumption of the electronic device is increased, and performance is also affected. In addition, under the scene that the whole electronic equipment is high in load and high in load application is opened, the synthesis time is too long, so that the synthesis cannot be completed within one frame time, and the problems of frame loss and clamping are caused.

Therefore, special effect processing of the electronic device in the synthesis stage needs to force GPU synthesis, so that high load of the GPU is caused, and product smoothness and user experience are affected.

Based on the technical problems, the embodiment of the invention provides a special effect processing system. Fig. 4 is a block diagram of a special effect processing system according to an embodiment of the present invention.

As shown in fig. 4, the special effects processing system includes a current application 210, a viewroot repl system 221, a WMS system 222, a rendering thread (render thread) 231, a libg ui system library 232, a compositing thread (SurfaceFlinger) 233, a shared memory (shared memory) 234, an open image language (Open Graphics Library, openGL) 234, a compositing Display module (hwcompound) 240, a frame buffer (frame buffer) 251, a graphics processor driver (GPU DRV) 252, and a Display device (Display) 260. The current application 210 belongs to the application layer of the electronic device. The ViewRootImpl system 221 and the WMS system 222 belong to the window management and control process 220 of the java framework layer of the electronic device. Rendering thread 231, LIBGUI system library 232, composition thread 233, shared memory 234, and open image language 234 belong to the local framework layer of the electronic device. The composite display module 240 belongs to a hardware abstraction layer of the electronic device. The frame buffer 251 and the graphics processor driver 252 belong to the kernel layer of the electronic device. The display device 260 belongs to the hardware layer of the electronic device.

In the embodiment of the present invention, the currently running application program of the electronic device is the current application 210, and the screen of the electronic device displays the interface of the current application 210, where the interface is dynamically displayed by multiple frames of images according to the synthesis sequence.

The current application 210 is configured to determine, according to the display interface of the current application 210, that the display interface is a target interface. Each frame of the multi-frame image of the display interface carries a target parameter, and the current application 210 can determine whether the display interface is a target interface to be specially processed according to the target parameter. The special effect processing includes blurring processing, shading processing, or rounding processing. If the current application 210 determines that the display interface is a non-target interface according to the display interface, the operation of displaying the interface of the current application is continuously executed, and the special effect processing operation is not executed on the display interface.

The current application 210 is further configured to determine, according to the target interface, special effect parameters of the target interface. Specifically, the current application 210 is configured to call the special effect API according to the target interface, and set special effect parameters. The special effects parameters include special effects area and special effects type. For example, the special effect processing is blurring processing, and the special effect parameters include blurring region addView, blurring type setflurmode, and the like.

The current application 210 is also used to send special effect parameters of the target interface to the viewrootpmpl system 221. In addition to the above special effects parameters, during the rendering phase, the current application 210 will also call the API to invoke the specified resources and draw the content to be displayed in conjunction with the capabilities of the API.

The viewrootpmpl system 221 is configured to send the special effect parameters of the target interface to the WMS system 222.

WMS system 222 is configured to send the special effects parameters of the target interface to rendering thread 231.

Rendering thread 231 is used to send the effect parameters of the target interface to LIBGUI system library 232. The rendering stage, the API and data called by the current application 210 are synchronized to the rendering thread 231 in the form of a view tree, and the rendering thread 231 converts them into instructions and texture data recognizable by the GPU through a 2D vector graphics processing function library (skia) for rendering.

LIBGUI system library 232 is configured to send effect parameters of the target interface to composition thread 233.LIBGUI system library 232 is also configured to send other layer parameters of the display interface to composition display module 240.

The composition display module 240 is configured to send other layer parameters to a frame buffer (frame buffer) 251.

In the current frame image synthesis stage of the target interface, the synthesis thread 233 is configured to obtain input data and a coloring program according to special effect parameters of the target interface, and store the input data and the coloring program into the shared memory 234. Specifically, in the pre-synthesis preparation stage of the current frame image synthesis stage of the target interface, the synthesis thread 233 obtains the input data and the coloring program according to the special effect parameters of the target interface, and stores the input data and the coloring program in the shared memory 234.

Taking special effect processing as blurring processing as an example, the coloring procedure is a Gaussian blurring algorithm. Gaussian blur is an image blur filter that uses normal distribution to calculate the transform for each pixel in an image, with the following formula:

wherein r is ² ＝x ² +y ² R is the blur radius, σ is the standard deviation of the normal distribution, and x, y are the two-dimensional coordinates of the image. The blur radius r determines the sharpness of the image, and the larger the blur radius, the more blurred.

Furthermore, in actual computing, the present embodiment does not use a conventional convolution kernel; but uses the blur radius r to make the blur in the X direction and the Y direction respectively, thus the blur effect is ensured, and the calculated amount can be effectively reduced.

Finally, due to the blurring effect, as shown in fig. 5, the embodiment of the invention firstly downsamples the input data and then carries out blurring processing, thereby greatly reducing the calculated amount; after blurring processing, the size is enlarged to the original size.

Similarly, when other special effects are processed, the embodiment of the invention firstly downsamples the input data and then carries out special effects processing, thereby greatly reducing the calculated amount; after the special effect processing, the original size is enlarged again.

In the next frame image rendering stage of the target interface, the rendering thread 231 is further configured to obtain the similarity between the current frame image and the next frame image according to the current frame image and the next frame image; if the similarity is greater than or equal to the first threshold, input data and a shading program are obtained from the shared memory 234, and a special effect processing layer is obtained according to the input data and the shading program. Specifically, the rendering thread 231 is configured to create a synthetic layer; performing special effect processing on the input data through a coloring program to obtain special effect data; and obtaining the special effect processing layer by taking the special effect data as the data of the synthesized layer.

If the similarity is smaller than the first threshold, the rendering thread 231 does not need to perform the operation of obtaining the special effect processing layer according to the input data and the coloring program; and in the next frame image synthesis stage of the target interface, the electronic equipment only stacks and combines other graphs participating in display to obtain the next frame image.

And in the next frame image synthesis stage of the target interface, the electronic equipment is used for laminating and synthesizing the special effect processing image layer and other images participating in display to obtain a next frame image. Specifically, composition thread 233 is used to send the special effects processing layer to open image language 234. The open image language 234 is used to send the special effects processing layer to the graphics processor driver 252. Graphics processor driver 252 is configured to drive the GPU to render the effect processing layer, and the result of the rendering is stored in frame buffer 251. The frame buffer 251 is used to generate a next frame image according to the result of the processing and other layer parameters, and send the next frame image to the display device 260. The display device 260 is used to display the next frame image.

The special effect processing method provided by the embodiment of the invention is intuitively described below by taking fuzzy processing as an example in combination with fig. 6. As shown in fig. 5, for a window that needs to do a blurring effect, the current application designates a blurring area (the default is the whole window, and an API can be called to designate the blurring area), and a blurring parameter is set; in the preparation stage of the current frame (N frame) image synthesis stage, the electronic equipment identifies the image layer according to the fuzzy parameters set by the current application, creates a fuzzy image layer, downsamples the image layer below the fuzzy image layer, calculates a final fuzzy region, generates fuzzy input data, generates a fuzzy coloring program (adopting a Gaussian fuzzy algorithm) according to the fuzzy parameters, and stores the fuzzy coloring program in a shared memory. In the rendering stage of the next frame (n+1th frame) image, after the electronic device identifies a rendering node, acquiring input data and a coloring program of fuzzy processing of the previous frame from the shared memory, identifying a corresponding render node (layer corresponding to the synthesis stage) when rendering the render layersimpl, creating a render node layer, and taking fuzzy data obtained after fuzzy processing is performed on the input data as data of the newly created render node layer; in the next frame (n+1st frame) image synthesis stage, the electronic device recognizes the render layer inserted in the rendering stage, superimposes the render layer and other layers involved in display to form a final picture to be displayed, i.e. a next frame image, and finally sends the next frame image to display.

As shown in fig. 7, since the GPU load of the special effect processing algorithm (such as the fuzzy processing algorithm) is low, the input data and the coloring program required by the special effect processing are prepared in the synthesis stage (i.e., the surfeflinger processing stage) of the nth frame image, and the GPU is used for performing the real special effect processing when the n+1th frame image is rendered, so that the phenomena of power consumption increase, frame loss and clamping caused by high load of the GPU due to the synthesis of the GPU in the synthesis stage are avoided.

Therefore, the embodiment of the invention transfers the special effect processing from the GPU synthesis stage to the rendering stage to be completed, so that the situation that the special effect processing needs to force GPU synthesis in the synthesis stage is avoided, and the product smoothness and the user experience are improved.

According to the embodiment of the invention, the special effect processing is transferred from the GPU synthesis stage to the rendering stage, so that the situation that the special effect processing needs to force GPU synthesis in the synthesis stage is avoided, and the product smoothness and the user experience are improved.
