Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a frame rate adjustment method provided in an embodiment of the present application, which is applicable to refresh and adjust a frame rate of an image displayed by an application program run by a terminal device, where the method may be executed by the terminal device provided in the embodiment of the present application, and a frame rate adjustment device of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
step S101, acquiring a current frame image and a historical frame image pushed by an application program, and determining image variation of the current frame image and the historical frame image.
The application program is an application installed in the terminal device, and may be a game application program, a live broadcast application program, or another application program with a high requirement for image display. The frame image is a still image picture, and the frame is a single image picture of the minimum unit in the image motion picture. The current frame image is a frame image to be displayed by the display unit of the terminal equipment, and the historical frame image is a frame image which is displayed by the display unit of the terminal equipment and is finished. During the operation of the terminal device, for example, when the game application program is running, the image is always refreshed and displayed at a higher frame rate (e.g., 60Fps), and in some cases, the refreshing and displaying at such a high frame rate are not required to be maintained, which causes higher resource consumption.
The application program prepares frame data to be drawn, and after the preparation is finished, the frame data is pushed to a Central Processing Unit (CPU) for control Processing, and then the image is rendered and drawn by a Graphics Processing Unit (GPU) and finally displayed through a display screen of the terminal equipment. In the application, before the image is drawn by the GPU, the frame rate of the current frame image is adjusted.
In one embodiment, a current frame image pushed by an application program is acquired, and a displayed historical frame image is drawn, wherein the historical frame image can be acquired through data pushed by a display unit of the terminal equipment, and can also be acquired through the application program with a historical image storage function, and the current frame image can also be acquired from a storage data pool.
In one embodiment, the image variation amount represents a variation degree of the current frame image and the displayed historical frame image, and may be a parameter obtained by performing normalization, and the parameter value ranges from 0 to 1. Optionally, the image variation may be at least one of a geometric variation, a displacement variation, and a scaling variation, and accordingly, the geometric variation, the displacement variation, and the scaling variation are parameters obtained after normalization. The geometric body is used as a basic unit for forming an image picture, and the image data of the current frame image and the historical frame image which are obtained contain a vertex and a topological boundary, so that the coordinate and the size of the geometric body can be determined, and the geometric body variation (representing the variation of the size and the quantity of the geometric body in the frame image) is obtained through normalization processing; when the displacement variation is determined, respectively marking a horizontal axis and a vertical axis of the display screen as a coordinate system from 0 to 1, mapping the geometric body into the coordinate system according to the position of the geometric body in a frame image picture, thereby obtaining the geometric body with the vertex coordinate from 0 to 1, and further calculating the displacement variation of the geometric body (representing the variation of the displacement of the geometric body in the frame image); when the scaling variation is determined, the resolution corresponding to the geometric object may be determined according to the vertex and the topological boundary of the geometric object in the frame image, and the resolution is divided by the resolution of the entire frame image to obtain the scaling variation (representing the scaling variation of the geometric object in the frame image).
In an embodiment, the image variation of the current frame image and the historical frame image is obtained through an image normalization processing algorithm, which may specifically be:
and S102, acquiring the current motion state of the terminal equipment, and determining an image variation threshold according to the motion state.
In one embodiment, the current motion state of the terminal device is determined by acquiring data collected by a sensor (such as a gravity sensor or an acceleration sensor) integrated with the terminal device, wherein the motion state comprises a static state and a moving state. Determining an image variation threshold according to the motion state includes: if the terminal device is in a stationary state, setting an image variation threshold as a first preset threshold, and if the terminal device is in a moving state, setting the image variation threshold as a second preset threshold, where the first preset threshold is greater than the second preset threshold, for example, the first preset threshold is 0.5, and the second preset threshold is 0.4.
Step S103, comparing the image variation with the image variation threshold, and if a preset condition is satisfied, discarding the current frame image or displaying the current frame image according to an update frame rate.
In one embodiment, the preset condition that the image variation amount satisfies may be that the image variation amount is smaller than a determined image variation amount threshold, after the image variation threshold is determined in step S102, fine adjustment may be further performed, specifically, the floating may be performed after the image display characteristics of different applications are determined to be the first preset threshold or the second preset threshold, for example, if the image variation threshold is determined to be the second preset threshold in step S102, for the application program with frequent image change and more scene change, the image change amount can be further reduced on the basis of the second preset threshold (for example, the second preset threshold minus 0.2 is used as the image change amount threshold finally used for comparison), and for the application program with frequent image change and more scene change, the image change amount is not frequent, i.e., applications with more static scenes, may increase by a fixed amount (e.g., 0.2) based on the second predetermined threshold.
In one embodiment, the image variation includes at least one of a geometry variation, a displacement variation and a scaling variation, and when the image variation is only one variation (e.g., any one of the geometry variation, the displacement variation and the scaling variation), only whether the variation is smaller than the determined image variation threshold is calculated; if the image variation includes any two or three of the image variations, the preset condition is satisfied that each type of variation parameter is smaller than the respective determined image variation threshold (the image variation threshold corresponds to the image variation, and if the image variation is a geometric variation and a displacement variation, the image variation threshold determined in step S102 also includes the geometric variation threshold and the displacement variation threshold). Illustratively, as shown in fig. 2, fig. 2 is a schematic diagram of a determined image variation threshold provided in an embodiment of the present application, where the image variation includes three types of geometric variation, displacement variation, and zoom variation, and accordingly, the determined image variation thresholds corresponding to the two types of geometric variation thresholds are sequentially set to 0.5, 0.32, and 0.48, and when the geometric variation of the determined current frame image and the geometric variation of the determined historical frame image are less than 0.5, the displacement variation is less than 0.32, and the zoom variation is less than 0.48, the following steps are performed: and discarding the current frame image or displaying the current frame image according to the updated frame rate.
The updated frame rate is less than the original frame rate of the current frame image, and if the original frame rate of the current frame is 60Fps, the updated frame rate may be 30 Fps. For example, when the current frame image is displayed at the updated frame rate, the updated frame rate may be obtained by multiplying the original frame rate of the current frame image by a fixed coefficient (e.g. 0.3, 0.5, or 0.8, etc.), and the current frame image is refreshed and displayed according to the updated frame rate, or the updated frame rate may be obtained by subtracting the fixed value (e.g. -20, 30, or 50, etc.) from the original frame rate of the current frame image. And discarding the current frame image, namely, directly skipping the current frame image without rendering and drawing, and acquiring the next frame image and performing corresponding similar adjustment processing.
Optionally, fig. 3 is a flowchart of another frame rate adjustment method according to an embodiment of the present invention, where when the image variation includes a geometric variation, a displacement variation, and a scaling variation, the current frame image and the historical frame image are correspondingly compared to determine the geometric variation, the displacement variation, and the scaling variation, respectively, where if it is detected that any one of the variations does not satisfy the condition (i.e., is greater than or equal to a corresponding determined image variation threshold), it is determined that the current frame rate adjustment condition is not satisfied, the frame rate adjustment is not performed, and the remaining variations do not need to be determined and a determination is made whether the remaining variations satisfy the condition. Specifically, the method comprises the following steps:
step S1011, acquiring a current frame image and a historical frame image pushed by an application program, and determining image variation of the current frame image and the historical frame image.
Step S1012, acquiring a current motion state of the terminal device, and determining an image variation threshold according to the motion state.
Illustratively, the image variation threshold includes: a geometry variance threshold of 0.5, a displacement variance threshold of 0.32, and a scaling variance threshold of 0.48.
Step S1013, determining the geometric variation of the current frame image and the historical frame image;
step S1014, determining whether a first preset condition is satisfied (wherein the first preset condition may be that the geometric variation is less than 0.5), if so, executing step S1015, otherwise, executing step S1020;
step S1015, determining displacement variation of the current frame image and the historical frame image;
step S1016, determining whether a second preset condition is satisfied (wherein the second preset condition may be that the displacement variation is smaller than 0.32), if so, executing step S1017, and if not, executing step S1020;
step S1017, determining the scaling variable quantity of the current frame image and the historical frame image;
step S1018, determining whether a third preset condition is met (wherein the third preset condition may be that the zoom variation is smaller than 0.48), if so, executing step S1019, and if not, executing step S1020;
step S1019, discarding the current frame image or displaying the current frame image according to the updated frame rate.
And step S1020, drawing the image according to the original frame rate of the current frame image.
According to the content, in the process of drawing the frame image provided by the application program, the corresponding image variable quantity threshold is determined according to the motion state of the terminal device, when the terminal device is in a moving state, the frame rate adjustment of the displayed image is performed with small probability, when the terminal device is in a static state, the probability of performing the frame rate adjustment is increased, and on the premise that the user experience and the application program performance are not influenced, the power consumption of the terminal device is saved.
Fig. 4 is a flowchart of another frame rate adjustment method provided in an embodiment of the present application, where optionally, the determining an image variation amount of the current frame image and the historical frame image includes: and judging whether the application program is an application program in a preset list or not, or judging whether a display image of the application program is rendered through openGL or not, and if so, determining the image variation of the current frame image and the historical frame image. As shown in fig. 4, the technical solution is as follows:
step S201, acquiring a current frame image and a historical frame image pushed by an application program, and determining image variation of the current frame image and the historical frame image.
Step S202, judging whether the application program is the application program in the preset list, if so, executing step S203, and if not, executing step S205.
The configuration mode of the preset list comprises a local configuration mode and an online pushing mode, the local configuration mode is stored under a/system/etc/arc.ini directory, the online configuration mode is stored under a/data/system/arc.ini directory, the list of the online configuration directory is preferentially read, if the preset list in the online configuration directory does not exist, the preset list under the local configuration directory is read, and if the local preset list is abnormal, the step S203 or the step S205 can be directly executed.
In an embodiment, the preset list is determined through testing, and specifically, the test contents of the application programs in the preset list include a performance test, a power consumption test and a stability test. The performance test comprises the steps that when the frame rate adjusting method of the scheme is executed, the application program is guaranteed to run without jamming, and the associated application of the application program can run normally and is not influenced by the frame rate adjusting method; the power consumption test comprises the steps of ensuring that the terminal equipment is not influenced in endurance and standby, and obviously saving electricity when the frame rate adjusting method is implemented in the operation process of the application program in the preset list (for example, 88mA electricity is saved to the maximum extent when the application program executes the frame rate adjusting scheme of the application, and the electricity saving proportion is 31%); the stability test comprises that the phenomena of flash back and restart are not generated in the running process of the application program. Optionally, when the application programs in the preset list are primarily screened, Top200 applications published in the application mall may be individually tested to determine the preset list, and the static scene and the dynamic scene proportion of the application programs may be considered simultaneously in the screening process, and the application programs with the static scene proportion greater than 10% may be listed in the preset list.
Step S203, determining whether the display image of the application program is rendered through openGL, if so, executing step S204, otherwise, executing step S205.
The method may further include determining whether to render and draw the image through Vulkan (cross-platform 2D and 3D drawing application program interface), if so, performing step S204, and if not, performing step S205.
Step S204, acquiring the current motion state of the terminal equipment, determining an image variation threshold according to the motion state, comparing the image variation with the image variation threshold, and if a preset condition is met, discarding the current frame image or displaying the current frame image according to an update frame rate.
And step S205, drawing the image according to the original frame rate of the current frame image.
Therefore, the frame rate of the application program in the preset list or the application program for image display through a specific rendering and drawing mode is adjusted, wherein the application program in the preset list is selected through strict tests, and the power consumption of the terminal device is saved to the greatest extent on the premise that the normal operation of the application program is guaranteed without influencing the user experience.
Fig. 5 is a flowchart of another frame rate adjustment method provided in an embodiment of the present application, where optionally, the determining an image variation amount of the current frame image and the historical frame image includes: and judging whether the image drawing frame rate in the historical frame image is greater than a frame rate threshold value, if so, determining the image variation of the current frame image and the historical frame image. As shown in fig. 5, the technical solution is as follows:

Wherein the preset time period may be 1 second, 2 seconds, 3 seconds, or the like.
Step S302, judging whether the image drawing frame rate in the history display frame image is larger than a frame rate threshold value, if so, executing step S303, otherwise, executing step S305.
Optionally, if the frame rates of the displayed historical display frame images are all greater than the frame rate threshold (e.g., 60Fps), it is determined that the frame rates need to be adjusted to save power consumption, and step S303 is performed.
Step S303, acquiring a current frame image and a historical frame image pushed by an application program, and determining image variation of the current frame image and the historical frame image.
Step S304, acquiring the current motion state of the terminal equipment, determining an image variation threshold according to the motion state, comparing the image variation with the image variation threshold, and if a preset condition is met, discarding the current frame image or displaying the current frame image according to an update frame rate.
And step S305, drawing the image according to the original frame rate of the current frame image.
As can be seen from the above, the frame rate of the application display image continuously displayed at the high frame rate is adjusted, so as to save the power consumption of the terminal device by discarding the frame or reducing the frame rate of the frame.
Fig. 6 is a flowchart of another frame rate adjustment method provided in the embodiment of the present application, and optionally, the discarding the current frame image or displaying the current frame image according to a preset frame rate includes: and if the previous frame image of the current frame image is not adjusted, discarding the current frame image or displaying the current frame image according to a preset frame rate. As shown in fig. 6, the technical solution is as follows:
step S401, acquiring a current frame image and a historical frame image pushed by an application program, and determining image variation of the current frame image and the historical frame image.
Step S402, acquiring the current motion state of the terminal equipment, and determining an image variation threshold according to the motion state.
Step S403, comparing the image variation with the image variation threshold, and determining whether the image variation satisfies a preset condition, if yes, performing step S404, and if no, performing step S406.
Step S404, determining whether the frame rate of the previous frame image of the current frame image is adjusted, if not, performing step S405, and if so, performing step S406.
Wherein, the step of determining whether the frame rate of the previous frame image has been adjusted includes whether the previous frame image is discarded or the frame rate is reduced for image drawing and displaying, and if the previous frame image is found to have been subjected to the corresponding frame reduction processing, the step of not adjusting the frame rate of the current frame image is executed, that is, the step S406 is executed.
Step S405, discarding the current frame image or displaying the current frame image according to the updated frame rate.

In one embodiment, the image variation includes at least one of a geometry variation, a displacement variation and a scaling variation, and when the image variation is only one variation (e.g., any one of the geometry variation, the displacement variation and the scaling variation), only whether the variation is smaller than the determined image variation threshold is calculated; if the image variation includes any two or three of the image variations, the predetermined condition is satisfied that each type of variation parameter is smaller than a respective determined image variation threshold (the image variation threshold corresponds to the image variation, and if the image variation is a geometric variation and a displacement variation, the corresponding determined image variation threshold also includes the geometric variation threshold and the displacement variation threshold).
The updated frame rate is less than the original frame rate of the current frame image, and if the original frame rate of the current frame is 60Fps, the updated frame rate may be 30 Fps. For example, when the current frame image is displayed at the updated frame rate, the updated frame rate may be obtained by multiplying the original frame rate of the current frame image by a fixed coefficient (e.g. 0.3, 0.5, or 0.8, etc.), and the current frame image is refreshed and displayed according to the updated frame rate, or the updated frame rate may be obtained by subtracting the fixed value (e.g. -20, 30, or 50, etc.) from the original frame rate of the current frame image.
