Detailed Description
In order to make the objects, features and advantages of the present application more comprehensible, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to solve the defect that in the related art, the refresh rate reduction adjustment is performed on the whole image area on the display screen, so that the power consumption control and the image display effect cannot be effectively considered, a first embodiment of the present application provides an image refreshing method, such as fig. 1 is a basic flowchart of the image refreshing method provided in the present embodiment, where the image refreshing method includes the following steps:
and 101, acquiring a target area where a static picture is located in a current display interface.
Specifically, the display interface of the embodiment includes a dynamic picture and a static picture, where the static picture is a picture that is not updated in a preset time period in the current display interface, and the dynamic picture is a picture that is updated frequently in the preset time period.
Fig. 2 is a schematic diagram of a display interface provided in this embodiment, taking a video playing scene as an example, in fig. 2, a is a video playing area, B is a video brief introduction area, a area needs to be frequently updated to display a picture, that is, a display area of a dynamic picture, and contents of B area are usually kept fixed, that is, a display area of a static picture.
In this embodiment, firstly, the image data of the current display interface is obtained, and then the image data is compared with the preamble data frame, wherein the image data which is consistent in comparison is a picture which is not updated, namely a static picture, and finally, the position coordinates of the area where the picture is located on the display interface are determined.
Step 102, performing reduction adjustment on the initial refresh rate of the static picture to obtain a first refresh rate.
Specifically, in practical application, the display screen outputs an image frame at a certain refresh rate to realize image display, where the refresh rate is divided into a vertical refresh rate and a horizontal refresh rate, and the refresh rate in this embodiment generally refers to the vertical refresh rate, and the vertical refresh rate identifies how many times an image of the display screen is redrawn per second, and its unit is hertz. In this embodiment, the initial refresh rate (e.g. 60 Hz) of the still picture, that is, the refresh rate when the still picture and the dynamic picture in the previous display interface are refreshed as a whole, the embodiment considers that the still picture is not frequently updated, so that the meaning of maintaining the high refresh rate is not great, and thus the refresh rate of the still picture is independently adjusted to be lower than 25Hz. It should be appreciated that at the same time, the dynamic picture may still maintain the previous initial refresh rate, e.g., 60Hz.
Step 103, the image data refreshing target area of the display buffer area is called regularly according to the first refreshing rate.
Specifically, the display screen is correspondingly configured with a display buffer area RAM, the application processor AP of the electronic device sends the whole image data including the image data of the static picture and the dynamic picture to the display screen, the display screen caches the received image data in the display buffer area, and the display screen regularly calls the image data in the buffer area to refresh the image according to the refresh rate. Taking the example of a display screen with a resolution of 2400 x 1800, each frame of overall image data includes image data of 2400 groups of moving pictures and image data of still pictures. It should be understood that, when the image data corresponding to the still picture does not need to be updated, the step of calling the image data of the display buffer to refresh the target area at the first refresh rate is performed, and if the image data corresponding to the still picture needs to be updated, the AP is awakened to obtain the latest image data.
For a static picture, the embodiment calls the image data corresponding to the area where the picture is located in the display buffer area to refresh according to the refresh rate after the adjustment, because the static picture is kept unchanged for a long time, if the refresh rate is lower, a user is generally difficult to perceive the screen flash, that is, the static picture can still provide a better display effect, and because the refresh rate of the static picture is reduced, the processing frequency of related functional components is reduced, and the screen power consumption can be effectively saved. In addition, since the dynamic picture generates obvious screen flash under the low refresh rate, the dynamic picture of the embodiment can still maintain the previous initial refresh rate for refreshing, that is, a relatively high refresh rate is adopted, so that the display effect can be effectively maintained. Therefore, by the scheme of reducing and adjusting the refresh rate of the local display area provided by the embodiment, the compromise between the power consumption control and the picture display effect can be effectively realized.
It should be noted that, when the refresh rate adjustment is performed on the static picture in this embodiment, the adjustment may be performed in two ways, that is, increasing the refresh time period of the row data corresponding to the static picture, and increasing the refresh time period of the pixel data in the row data corresponding to the static picture.
In some implementations of the present embodiment, before acquiring the target area where the still picture is located in the current display interface, the method further includes: determining a supportable refresh rate of the system according to the current system power consumption; the initial refresh rate of the display interface is compared to a refresh rate supportable by the system.
Specifically, in practical applications, the main consideration of performing refresh rate adjustment is to save system power consumption, but in this embodiment, it is considered that if the system power consumption is low, the necessity of system power consumption control is reduced, and blind reduction of the refresh rate may also bring about an influence of reduction of the potential display effect. Based on this, the embodiment first determines the supportable refresh rate of the system based on the current system power consumption, then compares the supportable refresh rate with the initial refresh rate when the dynamic/static images of the display interface are refreshed as a whole, and when the initial refresh rate is higher than the supportable refresh rate of the system, the necessity of controlling the system power consumption is described before triggering and executing the step of acquiring the target area where the static image in the current display interface is located, thereby improving the rationality and effectiveness of the refresh rate reduction adjustment.
In some implementations of the present embodiments, when the display interface includes a plurality of different still pictures, reducing the initial refresh rate of the still pictures includes: respectively determining the refresh rate adjustment quantity corresponding to each static picture; and respectively carrying out reduction adjustment on the initial refresh rate of each static picture according to the adjustment amount of each refresh rate.
Specifically, in practical applications, the current display interface may include a plurality of still pictures in different areas, as shown in fig. 3, which is a schematic diagram of another display interface provided in this embodiment, and also takes the foregoing video playing scene as an example, in fig. 3, a is a video playing area, B is a video brief introduction area, and C is a video evaluation area, where the picture displayed in the area a is a dynamic picture, and the pictures displayed in the areas B and C are all still pictures. In the embodiment, the types of the plurality of static pictures are considered to be different, the corresponding refresh rate adjustment amounts are respectively determined for the plurality of static pictures, the refresh rate reduction adjustment is performed in a differentiated mode, the adaptability of the refresh rate adjustment can be effectively improved, and the compromise of power consumption control and picture display effect is ensured to the greatest extent.
Further, in some implementations of the present embodiment, determining the refresh rate adjustment amounts for each static picture, respectively, includes: respectively acquiring user interaction function attributes corresponding to each static picture; a corresponding refresh rate adjustment is determined based on the user interaction function attribute.
Specifically, in practical applications, the interactive functions provided by different types of static pictures to the user are different, so that the video profile area only provides the profile browsing function to the user, and the video evaluation area usually provides the evaluation input function to the user in addition to the evaluation browsing function, so that the user interaction depths of different static pictures are different.
Fig. 4 is a flow chart of a refresh rate adjustment method provided in this embodiment, where in some implementations of this embodiment, when performing a reduction adjustment on an initial refresh rate of a static picture, the method specifically includes the following steps:
step 401, acquiring current system power consumption;
step 402, determining a corresponding refresh rate adjustment amount according to system power consumption;
step 403, performing reduction adjustment on the initial refresh rate of the static picture according to the refresh rate adjustment amount.
Specifically, the refresh rate adjustment amount of the present embodiment is positively correlated with the system power consumption. In this embodiment, considering that the system power consumption is different in different system operation scenarios, so that the requirements for controlling the system power consumption are correspondingly different, based on this, the embodiment correspondingly configures the refresh rate adjustment amount for different system power consumption, that is, when the current system power consumption is higher, the configured refresh rate adjustment amount is correspondingly higher, so as to ensure the power consumption control preferentially in the application scenario with higher power consumption; when the current system power consumption is relatively low, the configured refresh rate adjustment amount is relatively low, and when the power consumption level is low, the picture display effect is ensured to the greatest extent.
Fig. 5 is a schematic flow chart of a dynamic picture refreshing method according to the present embodiment, in some implementations of the present embodiment, after the image data refreshing target area of the display buffer is invoked at a first refresh rate, the method further specifically includes the following steps:
step 501, detecting system power consumption in real time, and comparing the system power consumption with a preset power consumption threshold;
step 502, when the system power consumption is higher than the power consumption threshold, reducing and adjusting the initial refresh rate of the dynamic picture to obtain a second refresh rate;
step 503, the area where the dynamic picture is refreshed by the image data of the display buffer area is called at regular time according to the second refresh rate.
Specifically, in this embodiment, after the refresh rate of the static picture is reduced, the system power consumption is detected in real time in the subsequent display process, and the system power consumption control effect of reducing the refresh rate of the static picture before is evaluated according to the comparison result of the system power consumption and the power consumption threshold value, when the system power consumption is higher than the power consumption threshold value, that is, the system power consumption is still at a higher level, the refresh rate of the dynamic picture is further reduced and adjusted, and then the image data corresponding to the area where the dynamic picture is located in the RAM is called according to the adjusted refresh rate to perform picture refresh, so as to further perform power consumption control.
In some implementations of the present embodiment, after invoking the image data refresh target region of the display buffer at the first refresh rate, further comprising: detecting the dynamic picture in real time; when the dynamic picture is converted into a static picture, the image data of the display buffer area is regularly called according to a first refresh rate to refresh the area where the dynamic picture is located.
Specifically, in this embodiment, considering that the dynamic picture is not always a dynamic picture along with the continuous change of the application running scene, taking the video playing scene as an example, the video playing area displays the dynamic picture in the video playing process, and after the user pauses the video, the video playing area is displayed and converted into a static picture, and in order to control the power consumption of the display screen, the area where the original dynamic picture is located is refreshed by directly using the first refresh rate set for the original static picture.
Fig. 6 is a schematic flow chart of a static picture refreshing method provided in this embodiment, and in some implementations of this embodiment, after the image data refreshing target area of the display buffer is invoked at a first refresh rate, the method further specifically includes the following steps:
step 601, monitoring picture display effect parameters of a static picture in real time;
step 602, when the picture display effect parameter is lower than a preset parameter threshold, increasing and adjusting the first refresh rate to obtain a third refresh rate;
step 603, invoking the image data refreshing target area of the display buffer area according to the third refresh rate.
Specifically, in this embodiment, the screen display effect parameters may include: frame dropping rate, degree of frame jitter, etc. In this embodiment, after the static image is refreshed according to the refresh rate adjusted by the previous adjustment, the display effect of the static image is monitored in real time, and if the display effect is significantly reduced due to the effect of the reduction of the refresh rate, it is explained that the refresh rate adjusted by the previous adjustment may be excessively adjusted and cannot meet the basic display effect requirement, so that the refresh rate adjusted by the previous adjustment is moderately increased, and the refresh rate is used as a relief measure for excessively reducing the refresh rate of the previous adjustment, thereby ensuring the effectiveness and flexibility of the refresh rate adjustment.
Based on the technical scheme of the embodiment of the application, the target area where the static picture is located in the current display interface is obtained, wherein the display interface comprises a dynamic picture and a static picture; reducing and adjusting the initial refresh rate of the static picture to obtain a first refresh rate; and regularly calling the image data refreshing target area of the display buffer area according to the first refresh rate. By implementing the scheme of the application, the refresh rate of the static picture at the local part of the current display interface is selectively reduced and adjusted, and the display requirement of the static picture is generally relatively low, so that the overall display effect of the display interface is ensured to the greatest extent while the power consumption is effectively controlled.
The method in fig. 7 is a refined picture refreshing method according to a second embodiment of the present application, where the picture refreshing method includes:
step 701, obtaining a target area where a static picture is located in a current display interface, and obtaining current system power consumption.
Specifically, the display interface of the embodiment includes a dynamic picture and a static picture, where the static picture is a picture that is not updated in a preset time period in the current display interface, and the dynamic picture is a picture that is updated frequently in the preset time period.
Step 702, determining a corresponding refresh rate adjustment amount according to the system power consumption.
Step 703, performing reduction adjustment on the initial refresh rate of the static picture according to the refresh rate adjustment amount, to obtain a first refresh rate.
Specifically, the refresh rate adjustment amount in this embodiment is positively related to the system power consumption, and in this embodiment, the refresh rate adjustment amount is configured correspondingly for different system power consumption, that is, when the current system power consumption is higher, the configured refresh rate adjustment amount is correspondingly higher, so as to preferentially ensure power consumption control in an application scenario with higher power consumption; when the current system power consumption is relatively low, the configured refresh rate adjustment amount is relatively low, and when the power consumption level is low, the picture display effect is ensured to the greatest extent.
Step 704, invoking the image data refreshing target area of the display buffer area at a first refresh rate.
Specifically, for a static picture, the embodiment calls the image data corresponding to the picture in the display buffer area to refresh according to the refresh rate after the adjustment, because the static picture is kept unchanged for a long time, if the refresh rate is lower, the user is generally hard to perceive the screen flash, that is, the static picture still can provide a better display effect, and because the refresh rate of the static picture is reduced, the processing frequency of relevant functional components is reduced, and the screen power consumption can be effectively saved.
Step 705, monitoring the system power consumption in real time, and comparing the system power consumption with a preset power consumption threshold.
Specifically, in this embodiment, after the refresh rate of the static picture is reduced, the system power consumption is detected in real time in the subsequent display process, and the system power consumption control effect of reducing the refresh rate of the static picture before that is evaluated by the comparison result of the system power consumption and the power consumption threshold.
And step 706, when the system power consumption is higher than the power consumption threshold, reducing and adjusting the initial refresh rate of the dynamic picture in the display interface to obtain a second refresh rate.
Step 707, the area where the dynamic picture is refreshed by the image data of the display buffer is called at regular time according to the second refresh rate.
Specifically, in this embodiment, when it is determined that the real-time system power consumption is higher than the power consumption threshold, it is indicated that the system power consumption is still at a higher level, the refresh rate is further reduced and adjusted for the dynamic picture, and then the image data corresponding to the area where the dynamic picture is located in the RAM is called according to the adjusted refresh rate to perform picture refresh, so as to further perform power consumption control.
It should be understood that, the sequence number of each step in this embodiment does not mean the order of execution of the steps, and the execution order of each step should be determined by its functions and internal logic, and should not be construed as a unique limitation on the implementation process of the embodiment of the present application.
