Technical Field
The present disclosure relates to the field of image processing technologies, and in particular, to a display control method, a display control apparatus, a computer readable medium, and an electronic device.
Background
When the screen is turned off, the electronic device often controls the thread for display to sleep, such as drawing the thread, in order to save power. In this case, if the screen is turned off and then on, the display screen before the turn-off will have screen residues, and then the screen residues will be displayed directly when turned on. After the screen is restarted, the thread for displaying is awakened again, at the moment, the picture residues are cleared, and then the display picture before being closed is redrawn. Therefore, when the screen is turned off and turned on again, the display process of displaying, not displaying and displaying again is often performed, and the display process can generate a flickering visual effect under the observation of human eyes.

However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
Fig. 1 is a schematic diagram of a system architecture of an exemplary application environment to which a display control method and apparatus of embodiments of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include one or more of the terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used as a medium to provide communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others. The terminal devices 101, 102, 103 may be various electronic devices with image processing functions including, but not limited to, desktop computers, portable computers, smart phones, smart watches, tablet computers, and the like. It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, the server 105 may be a server cluster formed by a plurality of servers.
The display control method provided by the embodiments of the present disclosure is generally performed in the terminal devices 101, 102, 103, and accordingly, the display control apparatus is generally provided in the terminal devices 101, 102, 103. However, it will be readily understood by those skilled in the art that the display control method provided in the embodiment of the present disclosure may be executed by the server 105, and accordingly, the display control device may be disposed in the server 105, which is not particularly limited in the present exemplary embodiment. For example, in an exemplary embodiment, a target screen may be displayed in a first position of a screen of the terminal device 101, 102, 103, and the server 105 controls the terminal device 101, 102, 103 to transfer the target screen to a second position through the network 104 in response to dormancy of a rendering thread corresponding to the target screen; then, when the onResume method corresponding to the target picture is called in the terminal device 101, 102, 103, the server 105 controls the terminal device 101, 102, 103 to wake up the rendering thread through the network 104, and transfers the target picture re-rendered by the rendering thread to the first position, and so on.
Exemplary embodiments of the present disclosure provide an electronic device for implementing a display control method, which may be the terminal device 101, 102, 103 or the server 105 in fig. 1. The electronic device comprises at least a processor and a memory for storing executable instructions of the processor, the processor being configured to perform a display control method via execution of the executable instructions.
The configuration of the electronic device will be exemplarily described below using the mobile terminal 200 of fig. 2 as an example. It will be appreciated by those skilled in the art that the configuration of fig. 2 can also be applied to stationary type devices in addition to components specifically for mobile purposes. In other embodiments, mobile terminal 200 may include more or less components than illustrated, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware. The interfacing relationship between the components is shown schematically only and does not constitute a structural limitation of the mobile terminal 200. In other embodiments, the mobile terminal 200 may also employ a different interface from that of fig. 2, or a combination of interfaces.
As shown in fig. 2, the mobile terminal 200 may specifically include: processor 210, internal memory 221, external memory interface 222, universal serial bus (Universal Serial Bus, USB) interface 230, charge management module 240, power management module 241, battery 242, antenna 1, antenna 2, mobile communication module 250, wireless communication module 260, audio module 270, speaker 271, receiver 272, microphone 273, headset interface 274, sensor module 280, display screen 290, camera module 291, indicator 292, motor 293, keys 294, and subscriber identity module (subscriber identification module, SIM) card interface 295, among others. Wherein the sensor module 280 may include a depth sensor 2801, a pressure sensor 2802, a gyro sensor 2803, and the like.
Processor 210 may include one or more processing units such as, for example: the Processor 210 may include an application Processor (Application Processor, AP), a modem Processor, a graphics Processor (Graphics Processing Unit, GPU), an image signal Processor (IMAGE SIGNAL Processor, ISP), a controller, a video codec, a digital signal Processor (DIGITAL SIGNAL Processor, DSP), a baseband Processor and/or a neural network Processor (Neural-Network Processing Unit, NPU), and the like. Wherein the different processing units may be separate devices or may be integrated in one or more processors.
The processor 210 has a memory disposed therein. The memory may store instructions for implementing six modular functions: detection instructions, connection instructions, information management instructions, analysis instructions, data transfer instructions, and notification instructions, and are controlled to be executed by the processor 210.
The mobile terminal 200 implements display functions through a GPU, a display screen 290, an application processor, and the like. The GPU is a microprocessor for image processing, and is connected to the display screen 290 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 210 may include one or more GPUs that execute program instructions to generate or change display information. In some embodiments, the above-described process of transferring the target frame from the first location to the second location, and re-transferring to the first location, may be performed by the GPU. In addition, the GPU may also be used to perform rendering operations on a target screen, and the like.
In the related art, when the screen is closed and then opened, the screen is often subjected to a display process of displaying, not displaying and displaying again, and the display process can have a flickering visual effect under the observation of human eyes. For example, in a smart watch, the corresponding entry animation will be played when the badge pops up. However, when a badge is being displayed on a smart watch, if a user turns the screen of the smart watch off and then on, the badge may have a visual effect of being displayed, not being displayed, and being displayed again, i.e., a flickering visual effect. If the user opens the function of the screen-off of the homeowner and the screen-on of the wrist-lifting when using the smart watch, the probability of appearance of the flickering visual effect is higher.
In view of one or more of the problems described above, the present exemplary embodiment provides a display control method. The display control method may be applied to the server 105, or may be applied to one or more of the terminal devices 101, 102, 103, which is not particularly limited in the present exemplary embodiment. Referring to fig. 3, the display control method may include the following steps S310 and S320:
In step S310, when the target frame is displayed at the first position of the screen, the target frame is transferred to the second position in response to the sleep of the rendering thread corresponding to the target frame.
The first position may be such that the target picture is displayed in the screen when the target picture is located at the first position; the second position may be such that the target picture is not displayed in the screen when the target picture is in the second position. Specifically, the second position may be a position where the target screen is displayed outside the screen by performing panning based on the first position, that is, when the target screen is in the second position, the target screen is present, but the target screen cannot be displayed in the screen because the target screen is located outside the screen.
In an exemplary embodiment, when a target picture displayed on a screen is at a first position, a rendering thread corresponding to the target picture is dormant due to a screen being turned off, and thus a picture residue corresponding to the target picture appears at the first position of the target picture on the screen. At this time, the target picture may be removed from the screen by the main thread. For example, as shown in fig. 4, when a target screen 420 is displayed in a screen 410 of the smart watch and a drawing thread corresponding to the target screen 420 is dormant due to screen shutdown or the like, the target screen 420 is shifted from a first position of the screen 410 to a second position on the right side of the screen 410. By shifting the target picture to the second position, the target picture cannot be displayed in the screen, and therefore even if the rendering thread has been put to sleep by the system, the picture-residual cannot be emptied, and the picture-residual is not displayed in the screen.
In some exemplary embodiments, when the terminal device displays the target screen, a view layout corresponding to the target Activity may be created when the target Activity is started, and then a surface layer view is added in the view layout, so that the target screen is displayed through the surface layer view. The view layout may include various types of view layouts, such as FrameLayout, among others; the skin views may then include various types of skin views, such as SurfaceView, GLSurfaceView, etc.
When the target picture is a 3D picture, the corresponding surface layer view may be set to GLSurfaceView, so as to improve the rendering efficiency. For example, when a model of a 3D space is displayed in a smart watch, when the Activity corresponding to the model of the 3D space is started, a corresponding FrameLayout may be created, and then GLSurfaceView may be added to the FrameLayout, so that the display of the target screen may be realized at the GLSurfaceView.
In an exemplary embodiment, after transferring the target screen to the second position, the display at the first position may be problematic. For example, after GLSurfaceView is moved to the second location, the system may create another SurfaceView that displays the Activity of the next layer of the target Activity. In order to avoid the problem similar to the picture displaying the next-layer Activity, a preset non-main thread view can be added in the view layout corresponding to the target Activity. The preset non-main thread view refers to a view rendered by a thread other than the main thread, for example SurfaceView is a view rendered by a non-main thread.
In addition, since the main thread view (e.g. normal view) cannot cover other non-main thread views created by the system, a problem of displaying a next-layer Activity picture still occurs, and accordingly, the above-mentioned occlusion effect of the preset non-main thread view cannot be achieved by creating the main thread view.
It should be noted that the preset non-main thread view may be set differently according to different target frames, which is not limited in this disclosure. For example, assuming that the target picture is a 3D badge, since the 3D badge is a model displayed in one 3D space, the remaining space is displayed in black except for its own vivid color, at which time the preset non-main thread view may be set to a pure black view according to the background color of the 3D badge. For example, surfaceView, which is displayed in pure black, can be used as a preset non-main thread view when the target picture is a 3D badge.
By setting the preset non-main thread view, on one hand, after the surface layer view corresponding to the target picture is transferred to the second position, the preset non-main thread view is reserved at the first position, so that the system can be prevented from automatically creating other views to a certain extent; on the other hand, by setting the display hierarchy of the preset non-main thread view, even if the system creates other views, the other views can be blocked by the preset non-main thread view.
In addition, in order to ensure that the surface layer view of the target picture is not blocked by the preset non-main thread view, a display level of the surface layer view is required to be set at this time, so that the target picture is displayed on the upper layer of the surface layer view in the preset non-main thread view. For example, setZOrderMediaOverlay methods may be invoked to set GLSurfaceView.
In an exemplary embodiment, when the target picture is displayed through the skin view, the effect of transferring the target picture from the first position to the second position may be achieved by performing a preset transformation on the coordinate position of the skin view. For example, translationX of SurfaceView may be offset such that SurfaceView is shifted left or right in the X-axis direction, thereby shifting the target frame displayed at SurfaceView to the left of the left edge of the screen or to the right of the right edge of the screen. In addition, the coordinate position of the surface layer view can be changed through other forms of preset transformation, so that the target picture displayed by the surface layer view is transferred to a second position which is not displayed in the screen, and the form of the preset transformation is not particularly limited in the disclosure; meanwhile, on the basis that the second position can achieve the effect that the target picture is not displayed in the screen, the specific setting of the second position is not particularly limited.
In step S320, in response to invoking the onResume method corresponding to the target picture, the drawing thread is awakened, and the target picture re-drawn by the drawing thread is transferred to the first position.
In an exemplary embodiment, when the system invokes the onResume method corresponding to the target picture, the previously dormant rendering thread is awakened and the target picture is redrawn. At this time, in order to redisplay the target picture on the screen, the target picture may be shifted to the first position, so that redisplay of the target picture is realized in a scene such as restarting the screen.
In an exemplary embodiment, when the target picture is displayed through the skin view, the effect of transferring the target picture to the first position of the screen may be achieved by performing a preset inverse transformation on the coordinate position of the skin view. It should be noted that, the preset inverse transformation and the preset transformation are inverse transformation processes. That is, assuming that the preset transformation can change the position coordinate from a to B, the corresponding preset inverse transformation can restore the position coordinate from B to a.
For example, as shown in fig. 4, when the preset transformation pair SurfaceView is set to shift translationX in the X-axis direction, so that SurfaceView is shifted to the right, and thus the target frame 420 displayed in SurfaceView is shifted from the first position in the middle of the screen 410 to the second position on the right side of the right edge of the screen 410, correspondingly, as shown in fig. 5, the preset inverse transformation pair SurfaceView may be shifted to the left in the X-axis direction, and thus the target frame 520 displayed in SurfaceView is shifted from the second position on the right side of the right edge to the first position in the middle of the screen 510. In addition, different settings may be adopted for the preset inverse transformation according to different preset transformations, which is not particularly limited in the present disclosure.
Further, in some exemplary embodiments, at least one target object and an entry animation corresponding to the target object may be included in the target screen. At this time, in order to ensure the integrity of the display of the entry animation, after the target frame is transferred to the first position, the entry animation corresponding to the target object included in the target frame may be played. For example, when the target scene is a 3D badge with a black background, the 3D badge includes an entry animation. After the target picture is transferred to the first position, the entry animation corresponding to the 3D badge is played again, so that the problem that the entry animation is incomplete in display because the entry animation is played when the target picture is not transferred to the first position is solved.
The following describes in detail the technical solution of the present disclosure, taking the example of displaying a 3D badge on a smart watch, with reference to fig. 6:
The 3D badge is a model displayed in one 3D space, and the rest of the space is black except that the 3D badge itself has vivid colors in consideration of the display and power consumption problems of combining the appearance of the smart watch. If the user does not exit the display interface of the 3D badge before closing the screen, the screen becomes black and one piece when the screen is closed. Since the drawing thread of the 3D badge after the screen is closed is also dormant, the picture of the 3D badge cannot be completely emptied every time the screen is closed, and when the screen is restarted correspondingly, the residual 3D badge is displayed first. Afterwards, the drawing thread of the 3D badge wakes up again, the screen is emptied, then the 3D badge is drawn again, and then the entry animation corresponding to the 3D badge is played. In this case, a display process of displaying, not displaying, redisplaying, that is, blinking occurs.
To avoid the above, referring to fig. 6, the above blinking process can be avoided by: in step S610, a FrameLayout may be first displayed in a first position on the screen by the Activity of the 3D badge; in step S620, frameLayout adds a SurfaceView to display pure black, and then adds GLSurfaceView to display the 3D badge; in step S630, call setZOrderMediaOverlay method, causing GLSurfaceView to be set to setZOrderMediaOverlay (true); in step S640, in response to the rendering thread corresponding to the 3D badge being dormant, transferring GLSurfaceView from the first position to the second position of the screen by presetting translationX of transition change GLSurfaceView; in step S650, upon invoking onResume method corresponding to the 3D badge, translationX of change GLSurfaceView by preset inverse transformation, transitions GLSurfaceView to GLSurfaceView the first position in the screen.
In summary, in the present exemplary embodiment, by transferring the target frame to the second position that is not displayed in the screen when the drawing thread is dormant, it is avoided that the frame of the target frame before the screen is closed remains on the screen after the screen is restarted, and further, the flickering visual effect that easily occurs when the screen is closed and restarted is avoided.
It is noted that the above-described figures are merely schematic illustrations of processes involved in a method according to exemplary embodiments of the present disclosure, and are not intended to be limiting. It will be readily appreciated that the processes shown in the above figures do not indicate or limit the temporal order of these processes. In addition, it is also readily understood that these processes may be performed synchronously or asynchronously, for example, among a plurality of modules.
Further, referring to fig. 7, in the embodiment of the present example, there is further provided a display control apparatus 700 including a first transfer module 710 and a second transfer module 720. Wherein:
The first transferring module 710 may be configured to transfer, when the target frame is displayed at a first position on the screen, the target frame to a second position, where the first position causes the target frame to be displayed on the screen and the second position causes the target frame not to be displayed on the screen, in response to the rendering thread corresponding to the target frame being dormant.
The second transferring module 720 may be configured to wake up the drawing thread in response to invoking the onResume method corresponding to the target frame, and transfer the target frame re-drawn by the drawing thread to the first position.
In an exemplary embodiment, referring to fig. 8, the display control apparatus 800 further includes a screen display module 810 that may be used to create a view layout corresponding to a target Activity in response to the target Activity being initiated; a skin view is added in the view layout to display the target picture based on the skin view.
In an exemplary embodiment, the screen display module 810 may be used to add a preset non-main thread view in the view layout.
In an exemplary embodiment, the screen display module 810 may be configured to perform display hierarchy setting on the surface layer view, so that the surface layer view is displayed on top of the preset non-main thread view.
In an exemplary embodiment, when the target picture is a 3D picture, the skin view includes GLSurfaceView.
