In the above-described embodiment, when the performance parameter is less than or equal to the first prescribed threshold, the display parameter is adjusted to the target display parameter.

In the above embodiment, the adjusted target image frame and the target display parameter are input to the display chip, so that the display chip can rapidly display the image of the adjusted target image frame on the basis of the reduction operation.

In the above embodiment, by allocating a larger storage space to the storage space for buffering the image frame, it is beneficial to improve the problems of frame loss, playing pause and the like due to the fact that the buffer is full due to a smaller buffer space when a performance bottleneck occurs.
With reference to the first aspect, in some optional embodiments, the method further comprises:
when the performance parameter is larger than a second specified threshold, storing the image frame in the storage space with the second preset capacity in an initial storage space of the memory of the display chip, wherein the second specified threshold is larger than or equal to the first specified threshold;

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," and the like are used merely to distinguish one description from another, and are not intended to indicate or imply relative importance.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1 and fig. 2 in combination, an electronic device 10 is provided in this application, which can be used for displaying an image frame. The method for playing and displaying the image picture can be as follows: and playing the display image picture through the display screen or playing the image picture through projection of the projection lens. The electronic device 10 provided in the embodiment of the present application can reduce the resolution, the frame rate, and the like of the displayed or projected image when the performance bottleneck occurs or is about to occur, so as to alleviate the performance bottleneck of the system, and avoid that the displayed or projected image is jammed or not smoothly played due to the performance bottleneck.
The electronic device 10 includes a storage module 12 and a processing module 11 coupled to each other, and the storage module 12 stores therein a computer program which, when executed by the processing module 11, causes the electronic device 10 to execute a screen display method described below.
Of course, the electronic device 10 may also include other modules. For example, the electronic device 10 may further include a communication module 13 and a display chip 14. The communication module 13 is used for establishing a communication connection with other devices (e.g., a server) for receiving or transmitting multimedia information. Multimedia information includes, but is not limited to, images, video, and the like. The display chip 14 is used for outputting pictures according to the image frames and the display parameters. If the electronic device 10 uses a display screen to play the picture, the electronic device 10 may include a display module for displaying the picture.
Understandably, the electronic device 10 may be, but is not limited to, a smart phone, a Personal Computer (PC), a tablet computer, a projector, etc., and may be applied to a device for playing a display screen.
In the present embodiment, the processing module 11, the storage module 12, the communication module 13, the display chip 14 and the display module are electrically connected directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.
Referring to fig. 1, an embodiment of the present invention further provides a screen display method, which can be applied to the electronic device 10, and the electronic device 10 executes or implements steps of the screen display method, so as to solve the problem of screen display that a screen is jammed and not smoothly played due to a performance bottleneck of a system. Wherein, the method may include steps S210 to S230.
The steps in the screen display method shown in fig. 1 will be described in detail as follows:
in step S210, performance parameters of the electronic device 10 are obtained.
In this embodiment, the electronic device 10 may detect its own current performance parameter, so as to obtain its own performance parameter. The detected performance parameter refers to the idle operation processing capability of the electronic device 10, and the larger the performance parameter is, the larger the idle operation processing capability of the electronic device 10 is, and the smaller the operation processing load of the electronic device 10 is. The manner of detecting the performance parameters may be determined based on the actual situation.
For example, the electronic device 10 may record a maximum wait time for an image frame in memory of the display chip 14 of the electronic device 10, which may be a factor in the performance parameter. The longer the longest wait period, the smaller the current performance parameters of the electronic device 10. Based on this, a functional mapping relationship between the performance parameter and the longest waiting time can be established.
For another example, the electronic device 10 may detect a load of the processing module 11, an occupancy amount of a memory/cache of the electronic device 10, and the like. The load of the Processing module 11 may include a load of a Central Processing Unit (CPU), a load of a Graphics Processing Unit (GPU), and the load may refer to a percentage of a current operation amount of the Processing module 11 to an operation amount at a full load. The greater the load of the current load of the processing module 11, the less the idle computing processing capacity, i.e. the smaller the performance parameters of the electronic device 10. Based on this, a functional mapping relationship between the performance parameters and the load of the processing module 11 may be established.
Similarly, the occupancy of the memory of the electronic device 10 may refer to a percentage of the used capacity of the memory of the electronic device 10 (the memory may include a storage unit for buffering image frames, and may include the memory of the display chip 14 and the memory in the storage module 12) to the total capacity of the memory. The larger the memory footprint, the smaller the performance parameters of the electronic device 10. Based on the method, a function mapping relation between the performance parameters and the memory occupation amount can be established.
Understandably, the performance parameter may be calculated from a functional mapping relationship of one or more sub-parameters of the longest waiting time of the image frame, the load of the processing module 11, and the memory occupation amount. Each sub-parameter may be used to calculate a corresponding performance parameter. The functional mapping relationship among the longest waiting time, the load of the processing module 11, and the memory occupation amount among the performance parameters can be determined according to the actual situation. When the performance parameter is calculated by multiple sub-parameters, each sub-parameter can be set with a corresponding weight, and the weight can be set according to actual conditions.
For example, if the performance parameter may be calculated from the longest waiting time of the image frame, the load of the processing module 11, and the occupied memory amount, the weight occupation ratios corresponding to the longest waiting time, the load of the processing module 11, and the occupied memory amount may be 30%, 40%, and 30%, respectively.
Step S220, adjusting image frame parameters of the electronic device 10 according to the performance parameters to obtain a target image frame, where the image frame parameters include display parameters.
In this embodiment, the storage module 12 of the electronic device 10 may serve as a cache module for caching data. After receiving the image frames from the network, the electronic device 10 may buffer the image frames in its own storage module 12. Then, the processing module 11 adjusts the image frame parameters of the image frame display output based on the current performance parameters of the electronic device 10 to obtain the target image frame. The adjusted target image frame may be input into the memory of the display chip 14, so that the display chip 14 may perform subsequent display output on the target image frame.
Step S220 may include: when the performance parameter is smaller than or equal to a first designated threshold value, acquiring a target display parameter; adjusting the value of the original display parameter of the image frame in the storage module 12 of the electronic device 10 to the value of the target display parameter to obtain a target image frame, and storing the target image frame in the memory of the display chip 14 of the electronic device 10 to obtain the storage address of the target image frame.
In this embodiment, the first specified threshold is usually a performance parameter indicating that the current processing pressure of the electronic device 10 is large and the screen display and playback affecting the current image quality is affected. The electronic device 10 may store an association relationship between a first designated threshold and a display parameter in advance, and when the performance parameter is less than or equal to the first designated threshold, it indicates that a performance bottleneck occurs or is about to occur in the electronic device 10. At this time, the electronic device 10 may acquire the display parameter corresponding to the first specified threshold as the target display parameter based on the association relationship.
After the electronic device 10 decodes the image frames, when the image frames need to be played, the image frames in the storage module 12 generally need to be cached in a designated storage space in the memory of the display chip. The designated storage space is a Frame Buffer interval of the display chip 14, and the specific capacity of the designated storage space may be set according to actual conditions, and is used to store and update information such as a hardware image and a display storage address, so as to be output by the display chip 14.
Referring to fig. 3, it is understood that the electronic device 10 may buffer the video data received from the external device (e.g., a server, a set-top box of a television set, etc.) in its own storage module 12 after decoding the video data to obtain the image frame. It is assumed that the memory of the display chip 14 can be divided into a display chip memory a area and a display chip memory B area, wherein the memory a area is used as the above-mentioned designated storage space for caching the image frames (or target image frames) to be displayed and output by the display chip 14. The memory B area is a storage space of the display chip memory excluding the memory a area, and can be used as an unused storage space of the display chip memory. In the display and play process, when the performance parameter of the electronic device 10 is less than or equal to the first designated threshold, the image frame cached in the storage module 12 may be converted into a target image frame with a lower requirement on the operation processing capability under the adjustment of the processing module 11, and cached in the memory a area of the display chip 14, so that the display chip 14 displays and outputs the target image frame, thereby alleviating the performance bottleneck of the electronic device 10.
The first specified threshold may be a specified percentage of the full performance parameter, and may be determined based on the actual condition of the performance parameter. A full performance parameter may be understood as a performance parameter measured when the electronic device 10 is unloaded (or not performing a task). The specified percentage may be determined as a practical matter, for example, the specified percentage may be one of less than or equal to 40%. For example, a specified percentage is 20%, and if the full performance parameter is 100, then the first specified threshold is 20.
In this embodiment, the image frame parameters of the electronic device 10 include display parameters of the image frame before image adjustment (for convenience of distinguishing from the display parameters after adjustment, the display parameters before image adjustment may be referred to as first display parameters, and the display parameters after adjustment may be referred to as second display parameters), and the image frame parameters after adjustment include display parameters (i.e., second display parameters) of a target image frame obtained after image adjustment is performed on the image frame. The first display parameter includes, but is not limited to, at least one of a resolution, a frame rate, and an image format of the image frame. The second display parameter may include, but is not limited to, at least one of a resolution, a frame rate, and an image format of the target image frame. The first display parameter is of the same type as the second display parameter. For example, the first display parameter is the resolution of the image frame, and the second display parameter is the resolution of the target image frame.
Of course, in other embodiments, the display parameters may also include the image format of the output. The first display parameter may be an image format with a large memory footprint, such as an ARGB8888 format. The second display parameter may be in an image format with a small memory footprint, such as an RGB565 format. Understandably, if the RGB565 format is adopted for the pictures of the same content, the consumption of memory capacity and performance in the RGB565 format is reduced by about half compared with the ARGB8888 format.
In the present embodiment, step S220 can be understood as: the electronic device 10 may alleviate the performance bottleneck at or before the performance bottleneck occurs by processing one or more of the following combinations (the combination of the combinations may be selected according to practical situations, and is not specifically limited herein), and the processing is as follows:
reducing the resolution of the displayed picture;
reducing a frame rate of the displayed picture;
and converting the image format of the image frame into an image format with small memory occupation.
After the resolution and frame rate of the displayed picture are reduced or the image format is converted, the required operation processing amount of the electronic device 10 can be reduced in the picture display processing service, so that more operation resources can be freed for the electronic device 10 to alleviate the system performance bottleneck.
In this embodiment, the number of the first designated threshold may be one, or may be multiple. When the first designated threshold is one, the display parameter corresponding to the first designated threshold is one, and if the first designated threshold is multiple, the display parameters corresponding to the multiple first designated thresholds may be different, so as to adjust the definition of the displayed image in stages according to the current performance parameter of the electronic device 10.
For example, when the number of the first specified thresholds is plural, step S220 may include: when the performance parameter is less than or equal to the corresponding target designated threshold, adjusting the original display parameter of the image frame in the storage module 12 of the electronic device 10 to a target display parameter associated with the target designated threshold, so as to obtain the target image frame.
Understandably, the first specified threshold is associated in advance with the corresponding display parameter. When the first designated threshold is plural, the electronic device 10 may adaptively determine one of the plural first designated thresholds as the current target designated threshold and the display parameter associated with the target designated threshold. The larger the first specific threshold value is, the more the spare calculation processing resources of the electronic device 10 are, the larger the associated display parameter is, and the association relationship between the first specific threshold value and the display parameter may be set according to actual situations, but is not limited to the association relationship in the following example.
For example, if the first specified threshold includes 30% of full-scale performance parameters and 20% of full-scale performance parameters, the resolution of the display parameter associated with the 30% of full-scale performance parameters may be 1080P, the resolution of the display parameter associated with the 20% of full-scale performance parameters may be 720 p.1080p, the resolution of the display parameter may be 1920 p. 1920 × 1080 pixels, and the resolution of 720P may be 1280 × 720 pixels.
If the resolution initially output by the electronic device 10 is 4K (which may refer to a resolution of 4096 × 2160 pixels in length and width), and the current performance parameter of the electronic device 10 is less than 30% of the full-mark performance parameter and greater than 20% of the full-mark performance parameter, the target specification threshold is 30% of the full-mark performance parameter, at this time, after receiving the video data from the external device, the electronic device 10 may decode the video data to obtain a 4K image frame and buffer the 4K image frame in the storage module 12, and then compress the 4K image frame into a 1080P target image frame and buffer the target image frame in the specified storage space of the display chip 14 for the display chip 14 to output.
If the current performance parameter of the electronic device 10 is less than the 20% full performance parameter, the target designation threshold is the 20% full performance parameter. At this time, the electronic device 10 may compress the image frame with the resolution of 4K into a target image frame of 720P, and buffer the target image frame in a designated storage space of the display chip 14 for output by the display chip 14. At this time, in the picture adjustment process, the picture viewed from the display screen by the user can be automatically switched from the smooth 4K picture to the smooth 720P picture without any jam. Understandably, the smaller the current performance parameter is, the larger the span between the display parameter of the target image frame obtained after adjustment and the display parameter of the original image frame is.
Likewise, the first specified threshold may also be associated with a frame rate that is processed in a manner similar to the resolution. For example, a full performance parameter with a target specified threshold of 30%, may be associated with a frame rate of 30 fps. A full-scale performance parameter with a target specified threshold of 20% may be associated with a frame rate of 25 fps.
For example, when the performance of the electronic device 10 is normal, the frame rate of the output screen is 60 fps. When the current performance parameter of the electronic device 10 is less than the full performance parameter of 30% and greater than the full performance parameter of 20%, the target designation threshold is the full performance parameter of 30%. At this time, the electronic device 10 may adjust the frame rate of the output in the frame from 60fps to 30fps to reduce the operation load of the system, thereby alleviating the performance bottleneck of the system.
In the above embodiment, the first designated threshold may be multiple, which is beneficial for the electronic device 10 to determine corresponding display parameters based on the performance parameters to perform image display, and can flexibly adjust the image display output mode in a hierarchical manner, and ensure the image clarity of the display as much as possible while ensuring smooth playing of the image.
And step S230, displaying the picture according to the adjusted image frame parameters and the storage information of the target image frame.
In this embodiment, after obtaining the target image frame, the electronic device 10 may obtain the adjusted image frame parameters and the storage information of the target image frame. And then, displaying the picture according to the adjusted image frame parameters and the storage information of the target image frame by using the display chip 14.
Step S230 may include: inputting storage information of the target image frame and the target display parameters into a display chip 14 of the electronic device 10, wherein the storage information comprises a storage address of the target image frame; and displaying the target image frame based on the storage address and the target display parameter.
In the process of displaying the image, the electronic device 10 may input the storage address of the cached target image frame and the second display parameter into the display chip 14, so that the display chip 14 can obtain the storage address of the cached image frame currently required to be displayed and the display parameter of the image frame. After the display chip 14 obtains the storage address of the image frame that needs to be displayed currently and the display parameter of the image frame, the image that needs to be displayed currently can be output and displayed for imaging based on the display parameter and the storage address.
It should be noted that the conventional screen display principle is generally as follows: when a display screen is to be updated, the memory address of the new image frame is input to the display chip 14 before the next vsync signal is output.
In this embodiment, before outputting the next vsync signal, the corresponding frame rate, resolution, image format, etc. included in the second display parameter may be input to the display chip 14 together with the storage address of the new image frame in the memory of the display chip 14. Based on this, when the display chip 14 updates and displays a new picture, it will be reconfigured along with all the display parameters and will be effective at the same time when the next picture is displayed, so that the picture viewed by the user is not jammed or basically not jammed during the picture conversion and display, and the 'no-sense' adjustment of the picture is automatically realized.
For example, the image frames stored in the designated storage space (e.g., memory a area in fig. 3) of the memory of the display chip include original 4k image frames and 1080P image frames buffered after the system performance is stressed. In the process of playing the display image by the electronic device 10, the display chip 14 may first display and output the 4k image frames and then display and output the 1080P image frames based on the time sequence of the image frames in the buffer, so as to automatically reduce the resolution of the display image, thereby reducing the operation amount in the display process, and alleviating the performance bottleneck of the system.
In the foregoing embodiment, the electronic device 10 may adaptively adjust the display parameters of the picture displayed by the electronic device 10 based on the performance parameters of the electronic device, and when the performance is less than or equal to the first specified threshold, decrease the display parameters to alleviate the performance bottleneck, thereby being beneficial to improving the problem that the picture display is jammed and unsmooth due to the performance bottleneck.
In this embodiment, the method may further include other steps. For example, after the performance of the electronic device 10 returns to normal (i.e. the pressure of the current operation process is small, such as the current performance parameter is greater than the specified threshold), as an optional implementation, the method further includes: when the performance parameter is greater than a second specified threshold, storing the image frame in the storage module 12 of the electronic device 10 in a memory of a display chip 14 of the electronic device 10 to obtain storage information of the image frame; inputting the storage information of the image frame and the original display parameters of the image frame into the display chip 14; and outputting and displaying the image frame based on the storage address of the image frame and the display parameter through the display chip 14.
Understandably, the second designated threshold may be a parameter greater than or equal to the first designated threshold, and may be set according to actual conditions. When the current performance parameter of the electronic device 10 is greater than the second specified threshold, it indicates that the electronic device 10 can normally display the output screen with the high resolution display parameter. At this time, the image frames received by the electronic device 10 do not need to be compressed, and the image frames with the original display parameters may be directly cached in the designated storage space of the display chip memory, so that the display chip 14 performs subsequent output display. The designated storage space is a storage space when capacity is not expanded, and may be understood as an initial storage space.
In the above embodiment, when the performance parameter is greater than the second specified threshold, it generally indicates that the performance of the device returns to normal, and at this time, the displayed picture may also return to normal, so that the electronic device 10 may adaptively adjust the definition of the picture, and improve the user experience of the viewing user.
As an optional implementation manner, before step S220, the method further includes: recording the longest waiting time of the image frame in the memory of the display chip 14 of the electronic device 10; and when the longest waiting time is greater than or equal to a preset time, determining that the performance parameter is less than or equal to the first specified threshold.
Understandably, the longer the waiting time of the image frames in the memory of the display chip 14, generally means the more processing pressure of the electronic device 10, the smaller the corresponding performance parameters. When the longest waiting time of the image frame is greater than or equal to the preset time, it indicates that the current processing pressure of the electronic device 10 is large, and a performance bottleneck exists. Therefore, it may be determined that the performance parameter is less than or equal to the first specified threshold by the longest waiting duration being greater than or equal to the preset duration. The preset time duration is generally a time duration with a short time, and may be set according to an actual situation, for example, the preset time duration may be 500 milliseconds.
As an optional implementation manner, before step S230, the method further includes:
when the performance parameter is less than or equal to a first designated threshold value and the remaining storage capacity of the memory of the display chip 14 is greater than or equal to a first preset capacity, allocating a storage space with a second preset capacity from the remaining storage capacity to obtain a designated storage space for caching the image frame.
In this embodiment, the remaining storage capacity of the memory of the display chip 14 is greater than or equal to the first preset capacity, which indicates that the remaining memory of the electronic device 10 is more abundant, and a larger memory space may be allocated for image display and playback as a new designated storage space. The obtained designated storage space for caching the image frame is a new designated storage space, and the capacity of the new designated storage space is larger than that of the initial storage space. The image frames subsequently pre-cached in the designated memory space by the electronic device 10 may be cached in a new designated memory space, wherein the capacity of the new designated memory space is greater than the capacity of the initial memory space. The first preset capacity, the second preset capacity and the capacity of the first storage space may be set according to actual situations, and are not specifically limited herein.
As an alternative implementation, the manner of obtaining the new specified storage space may be: and when the residual storage capacity of the display chip memory is larger than the initial storage space, allocating the storage space larger than the initial storage space from the storage space with the residual capacity as a new appointed storage space. At this time, the second preset capacity is larger than the capacity of the initial storage space and smaller than the remaining capacity.
As an alternative implementation, the manner of obtaining the new specified storage space may be: and allocating a storage space with a second preset capacity from the storage space with the residual capacity, merging the storage space with the initial storage space, and taking the merged storage space as a new appointed storage space. At this time, the second preset capacity is a value smaller than the remaining capacity, and may be set according to actual conditions.
In this embodiment, the allocated storage space with the second preset capacity may be provided with a corresponding mark, so that the electronic device 10 finds the corresponding storage space by using the mark, so as to cache the subsequent image frame in the storage space with the second preset capacity or in a new designated storage space. The mark may be set according to actual conditions, may be a number, a character, or the like, and is used for the electronic device 10 to search a corresponding storage space to cache a subsequent image frame.
Understandably, when the CPU or the GPU is busy in the electronic device 10, based on the above design, by allocating a larger buffer/storage space to the designated storage space, the electronic device 10 can buffer a larger number of image frames, which is beneficial to improving the problem that the buffer space is smaller when a performance bottleneck occurs, so that the initial storage space is full, thereby causing frame loss, playing jams, and the like, and further beneficial to realizing smooth picture playing.
As an optional implementation, the method further comprises: when the performance parameter is larger than a second specified threshold, storing the image frame in the storage space with the second preset capacity in an initial storage space of the memory of the display chip, wherein the second specified threshold is larger than or equal to the first specified threshold; and after releasing all the image frames in the storage space with the second preset capacity, deleting the marks of the storage space with the second preset capacity for storing the image frames.
When the performance parameter is greater than the second specified threshold, it indicates that the idle operation processing capability of the electronic device 10 is more abundant, and it may not be necessary to reallocate a larger storage space for the specified storage space. If the designated storage space is already allocated with the storage space with the second preset capacity when the performance parameter of the electronic device 10 is greater than the second designated threshold, the subsequent image frames may be cached in the initial storage space, and after the image frames in the storage space with the second preset capacity are released, the storage space with the second preset capacity is cancelled, and the image frames are continuously played and displayed from the initial storage space.
In the foregoing embodiment, after the system performance of the electronic device 10 returns to normal, the allocated large storage space may be cancelled, so as to make more memory space for the electronic device 10, so as to facilitate processing other services.
