Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The image display control method provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
In the process of using electronic equipment such as mobile phones in daily life, games are scenes which are used by users and are very focused. In the existing graphics system, each frame of image needs three links of CPU drawing, GPU synthesis and display card driving (DisplayDriver), and in order to keep the stability of the graphics system, the system works according to a fixed Vsync period to update the image to a screen. Taking a frame rate of 60Hz as an example, as shown in fig. 1, the time from drawing to display on a screen of one frame of picture is about 50ms. Therefore, although the mode can keep stable output of the picture, the real-time performance of the picture is not high enough, and the requirement of game lovers on the response speed of the game cannot be well met.
In order to solve the above technical problems in the existing graphics system, the embodiment of the application provides an improved graphics system working method, which triggers the electronic device to enter a fast response mode by identifying a use scene with high requirements on real-time performance of pictures, such as games and videos, of the electronic device, and in this mode, the frequency of image display processing and synchronizing signals is increased, or the frequency of image display processing is increased and a graphics display processing link is optimized, so that the purposes of shortening the image display processing of each frame, improving the game response speed and reducing picture blocking are achieved.
Referring to fig. 2, fig. 2 is a flowchart of an image display control method according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
step 201, a use scene of the electronic device is identified.
In the embodiment of the application, the working mode of image display processing can be adjusted, such as a fast response mode, under the specific use scene, such as a game, a video and the like, with higher requirement on the picture real-time performance, and the working frequency of one or more processing links is at least increased under the mode, so that the image display processing time of each frame is shortened, the effect of improving the picture real-time performance is further achieved, and the requirement of a user on the picture real-time performance under the specific use scene is met.
The operating frequency of a processing link may refer to the clock frequency of the processing link, that is, the frequency of the processing link during operation, where the unit is Hz, and the operating speed of the execution module of the processing link may be determined, and the higher the general operating frequency, the shorter the corresponding processing time, so that by increasing the operating frequency of a certain processing link, the processing time of the processing link may be shortened. For example, for the CPU drawing link, by increasing the working frequency of the CPU, the processing time of the CPU for drawing the image can be increased, for example, after the working frequency of the CPU is increased from 60Hz to 120Hz, the processing time of one frame of image for drawing the CPU is correspondingly reduced from 16.7ms to 8.3ms.
Therefore, whether to adjust the working mode of the image display processing can be determined by identifying the use scene of the electronic device, and because the electronic device has higher real-time requirements on the picture under the use scene that the display image frame needs to be refreshed at a certain frame rate, whether the display image frame needs to be refreshed continuously at present can be determined by identifying the application program name, the application program attribute or the application interface and the like of the operation of the electronic device, so that the use scene of the electronic device is determined. For example, applications such as games, video, etc. run in which the display image frames need to be refreshed at a higher frequency, and thus the usage scenario can be determined by identifying the application program that the electronic device is running in.
Step 202, when the usage scenario of the electronic device is a preset usage scenario, the working frequency of at least one processing link of the image display processing is increased, so as to shorten the image display processing time of each frame, where the preset usage scenario includes a usage scenario in which an image frame needs to be refreshed, and the at least one processing link includes at least one of an image drawing link, an image processing link and an image display link.
When the use scene of the electronic equipment is identified as the preset use scene, the method can determine that the real-time requirement of the current scene on the picture is higher, and the working mode of the image display processing needs to be adjusted to meet the use requirement of a user, so that the working mode of the image display processing can be adjusted to be a quick response mode when the electronic equipment is identified to enter the preset use scene, and the real-time performance and the response speed of the picture are improved. The preset usage scenes are some usage scenes with high requirements on real-time performance of pictures, and can be set automatically by a system or set by user definition, for example, the usage scenes of applications such as games, videos and the like needing to refresh and display image frames.
Specifically, the working mode of the image display processing is adjusted to be a fast response mode, which can be to adjust the working frequency of at least one processing link of the image display processing to achieve the effect of shortening the time of each frame of image display processing, wherein the image display processing can be completed after three processing links of image drawing, image processing and image display are sequentially performed, that is, the working frequency of at least one processing link of the image drawing link, the image processing link and the image display link can be adjusted to shorten the processing time of at least one processing link, and the total image display processing time can be shortened by matching with the Vsync synchronization mechanism of the image display processing, that is, the working mode of switching the image display processing to be a fast response mode is realized.
In addition, when the electronic device is identified to exit the preset usage scenario, the quick response mode can be exited, and the original normal mode is switched back, for example, when the user is identified to exit the game, the quick response mode can be correspondingly exited.
It should be noted that, in the embodiment of the present application, since the working frequency of at least one processing link of the image display processing is increased, an idle state may exist between two adjacent frames of image display, for example, referring to fig. 4, after the working frequency of each processing link is doubled, an interval of 8.3ms exists between the times of performing the image display processing on the a frame image and the B frame image, and the interval is the idle state between the image displays; for another example, referring to fig. 5, after the working frequency of each processing link is increased and the Vsync synchronization mechanism is changed, the processing time of displaying one frame of image is one Vsync period, and a certain time interval (the time for performing CPU drawing and GPU synthesis by the B frame) exists between the time of performing image display processing on the a frame image and the B frame image, and this interval is the idle state between image displays. After the last frame of image is sent to the screen of the electronic equipment, the next frame of image needs to be waited for a certain time to be sent to the screen, so that in order to avoid that the brightness of the screen is darkened or turned off due to the fact that the pixels of the screen cannot be kept luminous because no image is sent to be displayed in an idle state, the use of the electronic equipment is affected, and the normal use requirement of a user cannot be met.
Optionally, the screen of the electronic device is a low temperature polycrystalline oxide (Low Temperature Polycrystalline Oxide, LTPO) screen that maintains an on state during each frame of image display processing.
The LTPO screen is a combination of Organic Light-Emitting Diode (OLED) screen main flow low-temperature polysilicon (Low Temperature Poly-Silicon, LTPS) and indium gallium zinc oxide (Indium Gallium Zinc Oxide, IGZO) schemes, the pixel leakage current is greatly reduced, and the minimum refresh rate of the screen can be 1Hz, that is, the pixel luminescence can be maintained for 1 second.
In other words, in one embodiment, in order to well support the fast response mode of the image display processing, the electronic device may use the LTPO screen, so as to support the stability of the image display processing by using the characteristics that the LTPO screen has small electric leakage and the screen pixels emit light for 1 second, so that the electronic device can maintain stable image display in the fast response mode, and avoid darkening or flickering of the screen brightness.
Optionally, the step of increasing the operating frequency of at least one processing link of the image display processing includes:
adjusting the working frequency of each processing link of the image display processing from a first frequency to a second frequency, and adjusting the frequency of a synchronous signal from the first frequency to the second frequency;
The second frequency is higher than the first frequency, and each processing link is synchronously processed according to the synchronous signals.
In order to shorten the time of each frame of image display processing and realize a quick response mode, a plurality of different implementation modes are specifically available.
In the first embodiment, the method can be realized by uniformly increasing the working frequency of each processing link of the image display processing and correspondingly controlling the Vsync period, and shortens the time of each frame of image display processing on the basis of keeping the original processing links to synchronously process according to the Vsync signal.
Note that, the synchronization signal in the embodiment of the present application may be a Vsync signal commonly used in image display processing, and is mainly exemplified by the Vsync signal. The Vsync signal is used for triggering each processing link of the image display processing according to the Vsync period, ensuring the fixed display interval between frames and avoiding the jitter of pictures.
Specifically, the working frequency of each processing link of the image display processing can be increased from the first frequency to the second frequency, so that the time of a frame of image in each processing link is reduced, and meanwhile, as the processing time of each processing link is shortened after the working frequency is increased, the frequency of the Vsync signal can be correspondingly increased in order to ensure that each processing link can still be triggered according to the Vsync period, namely, the frequency of the Vsync signal is also adjusted from the first frequency to the second frequency, so that the Vsync period is consistent with the shortened processing period of each processing link. And in this embodiment, each processing section of the image display processing may be kept to be processed in synchronization with the Vsync signal.
For example, the working frequencies of three links of CPU drawing, GPU synthesis and DisplayDriver sending and displaying can be all increased to 120Hz from 60Hz, meanwhile, the Vsync signal frequency is also increased to 120Hz from 60Hz, and in specific implementation, the electronic equipment can send a control instruction through a System on Chip (SoC), so that the processing time of one frame of picture of the LTPO screen is activated from 16.7ms to 8.3ms, wherein pixels are updated from 0ms to 8.3ms, and 8.3ms to 16.7ms are in an idle state; meanwhile, the frequency of the Vsync signal is increased from 60Hz to 120Hz, the normal mode is switched to the quick response mode, and the processing time and the period of the Vsync signal before and after the switching are shown in FIG. 3. Therefore, the graphics system is switched to a state with the working frequency of 120Hz, at the moment, the graphics system link, namely CPU drawing, GPU synthesis and Display Driver sending and displaying in the image Display processing, only occupy 25ms together, compared with the common mode, the time of the graphics system link is shortened by 25ms, the real-time performance of the image is greatly improved, the game response speed can be greatly improved for the game use scene, and the game experience of a user is improved.
In this embodiment, the operation frequency of the image display processing and the frequency of the synchronization signal can be increased, so that the image display processing time per frame can be greatly shortened, and the system response speed can be greatly increased.
Optionally, the frame rate output by the electronic device in the preset usage scenario remains unchanged.
In one embodiment, to avoid increasing the power consumption of the device, the frame rate of the original output may be kept unchanged when the electronic device is in the preset usage scenario, that is, the number of frames of the image processed per second is kept unchanged.
Further, the second frequency is twice the first frequency, and after each processing link processes one frame of image, the next frame of image is processed after a processing period of one processing link is separated.
In some embodiments, the working frequency of each processing link (i.e., the image drawing link, the image processing link, and the image display link) of the image display processing and the frequency of the Vsync signal may be doubled, so that the time of each processing link is doubled, and for each frame of image, after each processing link is performed, a processing period of one processing link (i.e., a synchronization period of the Vsync signal) may be spaced, and then the processing of the next frame of image for the corresponding processing link may be started. That is, each frame of image can be skipped in the image processing link, that is, the next frame is not processed, so that each frame of image processing link is in an idle state, and the image drawing link of the next frame of image and the image display link of the previous frame of image are synchronously processed, so that the frame number of the image processed by the electronic equipment per second in the preset use scene can be kept unchanged, and the increase of power consumption can not be brought.
That is, in some embodiments, the frame rate may be kept unchanged under the preset usage scenario, that is, the number of frames of the image processed per second is kept unchanged, for example, the frame rate is 60Hz before the operation mode is switched, and after the preset usage scenario is entered to switch the operation mode, the frame rate is still 60Hz, that is, one image is always kept to be output every 16.7 ms.
As shown in fig. 4, in the fast response mode, the working frequencies of the three links including CPU drawing, GPU synthesizing and Display Driver are all doubled, that is, the frequency of the Vsync signal is doubled from 60Hz to 120Hz, the processing time and the Vsync period of each link after the improvement are shortened to 8.3ms from 16.7ms, but the frame rate is still kept at 60Hz, the next frame of image is processed every 16.7ms, and an image is output every 16.7 ms. In this embodiment, since the screen interval of the application output such as the game is fixed and always kept at 60Hz, the processing time of these units is shortened (from 16.7ms to 8.3 ms) and the number of processed screens is the same in the unit time (60 frames of image data are processed in 1 second in both the normal mode and the fast response mode) although the operating frequency of the CPU, GPU and other modules is improved in the fast response mode compared with the normal mode, and therefore the power consumption of the device is not significantly increased.
According to the embodiment, the purpose of shortening the display processing time of each frame of image and improving the response speed of the system can be achieved, and meanwhile, the increase of the power consumption of equipment is avoided.
Taking a game usage scenario as an example, the above first embodiment is illustrated with reference to fig. 4, and includes the following processing steps:
s11, clicking a game application by a user, and starting the game application after the system is identified, wherein the system frame rate is 60Hz;
step S12, the system recognizes that a game scene is entered, and switches to a quick response mode: by utilizing the characteristics that the LTPO screen has small electric leakage and the pixel luminescence can be maintained for 1 second, the SoC sends a control instruction to activate the processing time of one frame of picture of the LTPO screen from 16.7ms to 8.3ms (the pixel is updated in 0-8.3 ms, and the pixel is updated in 8.3 ms-16.7 ms and is in an idle state), and frame skipping can be carried out in the time, namely the next frame is not processed in the time; while the Vsync frequency increases from 60Hz to 120Hz, as shown in particular in fig. 3;
in the step S13, the graphics system is switched to 120Hz state, at this time, the CPU drawing, GPU synthesis, display Driver sending and displaying in the graphics system link only takes 25ms, which shortens 25ms compared with the normal mode, greatly improving the game response speed, as shown in fig. 4, since the screen interval of game output is fixed, and always keeps at 60Hz (one image is output every 16.7 ms), compared with the normal mode, although the operating frequency of the CPU, GPU and other modules is improved in this mode, the processing time of these units is shortened (reduced from 16.7ms to 8.3 ms), and in the idle state in the latter 8.3ms, the number of processed images in unit time is the same (60 image data are processed in 1 second in the normal mode and the fast response mode), and the power consumption of the device will not be increased significantly.
Step S14, the user exits the game, and after the system is identified, the user automatically exits the quick response mode.
In the first embodiment, for the game scene, the fast response mode can be entered by identifying the game scene, so that the response speed of the game screen is greatly improved, and the game experience of the user is improved.
Optionally, the working frequency of the at least one processing link after the step-up is higher than the frequency of the synchronous signal;
the image drawing link is synchronously processed according to the synchronous signals, the image processing link triggers processing when the image drawing link is finished, and the image display link triggers processing when the image processing link is finished.
In the second embodiment, the working frequency of each processing link of the image display processing may not be uniformly increased, but the frequency of any processing link may be adjusted, different working frequencies may be set for different processing links, and the original Vsync signal synchronization processing mechanism may be changed.
For example, the working frequency of CPU drawing and GPU synthesis can be increased, so as to shorten the drawing and synthesis time of each frame of image, change the synchronous trigger mechanism of GPU synthesis and Display Driver, not wait for Vsync period any more, only CPU drawing is triggered synchronously following Vsync signal, GPU synthesis is triggered immediately after CPU drawing is finished, and Display Driver is triggered immediately after GPU synthesis is finished. Therefore, the GPU synthesis and Display Driver Display do not need to wait for the triggering of the Vsync signal, but can be triggered immediately after the end of the last processing link, so that the processing time for displaying one frame of image can be shortened greatly.
It should be noted that in this embodiment, the Vsync signal frequency may be kept unchanged, for example, kept at 60hz, and the Vsync period is still 16.7ms, or the Vsync signal frequency may be adjusted according to the adjustment of the processing time of the image display of the subsequent frame.
In the embodiment, the image display processing time of each frame can be greatly shortened by improving the working frequency of the image display processing and adjusting the synchronization mechanism of each processing link, and the response speed of the system is greatly improved.
Optionally, the step of increasing the operating frequency of at least one processing link of the image display processing includes:
The working frequency of the image drawing link is adjusted from a first frequency to a third frequency, the working frequency of the image processing link is adjusted from the first frequency to a fourth frequency, and the working frequency of the image display link is adjusted from the first frequency to a fifth frequency, wherein the third frequency, the fourth frequency and the fifth frequency are all higher than the first frequency.
In some embodiments, in order to equalize the processing time of each link of the image display processing and control the total image display processing time of one frame, the working frequencies of the three links of the image display processing may be increased, and may be increased to different frequencies respectively.
For example, the working frequency of Display Driver is doubled on the basis of 60Hz, so that the processing time of one frame of picture of a screen is activated from 16.7ms to 8.3ms, the frequency of CPU drawing and GPU synthesis is increased to be higher than that of Display Driver, the processing of CPU drawing and GPU synthesis is accelerated, the time of image Display to the screen is relatively long, and the stability of the Display of the pixel image of the screen is maintained.
Optionally, in the case that the usage scenario of the electronic device is a preset usage scenario, the method further includes:
Respectively distributing processing time to the image drawing link, the image processing link and the image display link so as to control the display processing time of each frame of image not to exceed the synchronization period of the synchronization signal;
and determining the third frequency, the fourth frequency and the fifth frequency according to the processing time respectively allocated to the image drawing link, the image processing link and the image display link.
In some embodiments, the working frequency of each link of the image display processing can be reasonably adjusted to control the processing time of one frame of image display so as to enable the processing time not to exceed the synchronization period of the Vsync signal, so that the processing time of each frame of image display can be shortened, and the frame rate can be ensured not to be reduced.
Specifically, a frame image display processing time or a Vsync period can be determined according to a frame rate, and then a processing time is respectively allocated to an image drawing link, an image processing link and an image display link based on the time, so that the processing time sum of the three links is equal to or smaller than the frame image display processing time/Vsync period; and deducing corresponding working frequency based on the processing time allocated by each link.
As shown in fig. 5, in the fast response mode, the working frequency of Display Driver is adjusted from 60Hz to 120Hz, the processing time is activated from 16.7ms to 8.3ms, in the graphics system link, the CPU starts to draw according to the Vsync rhythm, the GPU synthesis and Display Driver do not wait for the Vsync period, but trigger immediately, and simultaneously, the CPU and GPU frequencies are increased, so that the processing time of CPU drawing, GPU synthesis and Display Driver Display is shortened, the processing time of displaying an image is greatly reduced from 50ms to 16.7ms, and the system can be kept to process an image every 16.7ms, so that the system frame rate is ensured to be unchanged at 60 Hz.
According to the embodiment, the aim of greatly shortening the display processing time of each frame of image and improving the response speed of the system can be achieved, and meanwhile, the frame rate of the system is not influenced.
It should be noted that, in a game scenario, often in a battle, because of the release skills of multiple persons, the load of the system CPU/GPU is high, the processing image in the normal mode often exceeds one Vsync period, so that the situation of picture jamming easily occurs, and compared with the normal mode, the situation of picture jamming is also greatly reduced in the fast response mode, as shown in fig. 6, in the normal mode, when the processing time of an a frame image is overtime (exceeds one Vsync period) due to the high load when the CPU draws, the next Vsync period needs to be waited for GPU synthesis, so that the total processing time reaches 66.7ms; in the fast response mode, when the processing of the a-frame image is overtime (beyond one Vsync period) due to high load in the CPU drawing, the next Vsync period is not needed to be waited, but the GPU synthesis can be directly performed immediately after the CPU drawing is finished, so that the total processing time can be greatly reduced to 33.3ms, and therefore, the picture stuck condition can be greatly reduced.
Optionally, after the step 202, the method further includes:
before the current frame image is processed in the image display link, determining the target starting time of the current frame image for the image display link processing according to the starting time of the image display link processing of the previous two frames of the current frame image or according to the preset time interval and the starting time of the image display link processing of the previous frame image of the current frame image;
and when the target starting time is reached, performing image display link processing on the current frame image, wherein the time interval of performing image display link processing on the current frame image and the previous frame image of the current frame image is the same as the time interval of performing image display link processing on the first two frame images of the current frame image, or is the preset time interval.
In the second embodiment, the image processing link and the display link in the fast mode are not triggered according to the fixed Vsync period, so that the problem of frame-to-frame interval is likely to occur, and the frame jitter is caused.
As shown in fig. 7, in the fast mode, the Display Driver sending and displaying link may add an appropriate delay Delta to the current frame according to the interval X of the previous frame, so that the frame interval remains the same, i.e. delta=x-Y, and the frame interval a- > B- > C frame in fig. 7 is consistent after adjustment.
The above second embodiment is illustrated below in conjunction with fig. 5, and includes the following processing steps:
s21, clicking a game application by a user, and starting the game application after the system is identified, wherein the system frame rate is 60Hz;
step S22, the system recognizes that a game scene is entered, and switches to a quick response mode: in a link of a graphic system, a CPU starts drawing according to a Vsync rhythm as same as a common mode in the processing time of one frame of picture of an LTPO screen (from 16.7ms to 8.3 ms), and GPU synthesis and Display Driver send Display do not wait for the Vsync period any more but trigger immediately; simultaneously, the CPU/GPU frequency is improved, the processing time of CPU drawing, GPU synthesis and Display Driver transmission is shortened, and the processing time of one frame of image is greatly reduced from 50ms, particularly as shown in an image A frame in FIG. 5;
in a game scene, often in a battle, because of the release skills of multiple persons, the load of a system CPU/GPU is high, the image processing in a common mode often exceeds a Vsync period, the situation of picture blocking easily occurs, and compared with the common mode, the situation of picture blocking is also greatly reduced, as shown in FIG. 6;
Step S23, GPU synthesis and Display Driver Display are not triggered according to a fixed Vsync period in a quick mode, the problem of frame-to-frame interval unfixed and picture jitter caused occurs, so that in a quick response mode, a Display Driver Display link adds proper delay (Delta in FIG. 7) according to the interval (X in FIG. 7) of a previous frame picture, so that the picture interval is kept the same, namely delta=X-Y, and the A- > B- > C frame picture interval is consistent as shown in FIG. 7, so that stable and smooth images can be ensured;
step S24, the user exits the game, and after the system is identified, the user automatically exits the quick response mode.
In the second embodiment, for the game scene, the fast response mode can be entered by identifying the game scene, so as to optimize the link of the graphics system, thereby achieving the purposes of improving the response speed of the game picture and reducing the jamming.
According to the image display control method, the use scene of the electronic equipment is identified; and under the condition that the use scene of the electronic equipment is a preset use scene, the working frequency of at least one processing link of image display processing is increased so as to shorten the display processing time of each frame of image, wherein the preset use scene comprises the use scene needing refreshing display of the image frames, and the at least one processing link comprises at least one of an image drawing link, an image processing link and an image display link.
