In the embodiment of the present invention, while receiving screen refresh rate adjustment instruction, the interface refresh rate of computing terminal current application; According to the interface refresh rate of described current application, adjust the screen refresh rate of described terminal.
In the embodiment of the present invention, described terminal can be the equipment that possesses intelligent Presentation Function, such as being: terminal devices such as smart mobile phone, panel computer ipad, computers.
Below in conjunction with the drawings and specific embodiments, the method for the invention and device are described further.
The embodiment of the present invention has proposed a kind of method of adjusting screen refresh rate, and as shown in Figure 1, the method comprises:
Step S100: while receiving screen refresh rate adjustment instruction, the interface refresh rate of computing terminal current application.
In this step, described screen refresh rate is adjusted instruction and is triggered according to setting-up time interval mode or Event triggered mode, and triggering mode specifically describes as follows:
Mode one, according to Event triggered mode, trigger, for example, when described terminal current application starts or wakes up, automatically send screen refresh rate and adjust instruction; Or, when described terminal current application switches, by current, should be switched to next when application, automatically send screen refresh rate and adjust instruction.
Mode two, according to setting-up time interval mode, trigger, after the setting-up time interval completing in last sampling, automatically send screen refresh rate and adjust instruction, within next default sampling time, recalculate the interface refresh rate of terminal current application, the interface refresh rate of computing terminal current application in real time, thus the screen refresh rate of described terminal adjusted in real time and dynamically; Setting-up time interval according to the actual requirements, for example, setting-up time is spaced apart 30ms, can reduce like this adjustment number of times of screen refresh rate in the unit interval, thereby improves the work efficiency of described terminal screen, and reduces the power consumption of described terminal.
In this step, while receiving screen refresh rate adjustment instruction, first, within the sampling time setting in advance, count in described terminal current application and carry out the number of image frames that interface is refreshed; Then, according to described number of image frames and sampling time, the interface refresh rate of computing terminal current application.Concrete implementation is as follows:
Mode one, at T

Mode three, count current triggering constantly before s in second, carry out the number of image frames n that interface is refreshed, and calculate interface refresh rate υ according to following formula:
υ＝n/s
Wherein, the interface of current application is refreshed to trigger and is triggered by touch screen mode or mouse click mode by user.
In this step, also can adopt other mode to calculate the interface refresh rate of terminal current application, the embodiment of the interface refresh rate of computing terminal current application not done to concrete restriction here.
Step S101: the screen refresh rate of adjusting described terminal according to the interface refresh rate of described current application.
In this step, initial screen refresh rate is the default value that system arranges, and the specific implementation of screen refresh rate of adjusting described terminal according to the interface refresh rate of current application is as follows:
First, according to actual interface refresh rate scope, an interface refresh rate threshold value is set, that is: the first interface refresh rate threshold value, conventionally, the span of the first default interface refresh rate threshold value was 5～20 frame/seconds, interface refresh rate is divided into two segmentations, and two scene modes of corresponding two subsection setups; That is: first mode and the second pattern, in order to take into account the compatible context of the screen parameter of visual effect and most of terminal, corresponding first mode arranges the first screen refresh rate, and corresponding the second pattern arranges the second screen refresh rate; Wherein, described the first screen refresh rate is lower than described the second screen refresh rate.
Concrete, if the interface refresh rate of described current application is less than or equal to described the first interface refresh rate threshold value, corresponding scene mode is first mode, the screen refresh rate of now adjusting described terminal is the first screen refresh rate, that is: according to screen, drive the interface providing, read the first screen refresh rate and current screen refresh rate, judge that whether the first screen refresh rate is identical with current screen refresh rate, if not identical, upgrading current screen change rate is the first screen refresh rate; If the interface refresh rate of described current application is greater than described the first interface refresh rate threshold value, corresponding scene mode is the second pattern, the screen refresh rate of now adjusting described terminal is the second screen refresh rate, thereby can dynamically adjust the screen refresh rate of terminal, to reach the object of the electric weight of saving terminal.
Preferably, also two suitable interface refresh rate threshold values can be set according to actual interface refresh rate scope, that is: the first interface refresh rate threshold value and second contact surface refresh rate threshold value, conventionally, the span of default second contact surface refresh rate threshold value was 5～10 frame/seconds, the span of the 3rd default interface refresh rate threshold value was 10～20 frame/seconds, and interface refresh rate is divided into three segmentations, and three scene modes of corresponding three subsection setups; That is: first mode, the second pattern and three-mode, in order to take into account the compatible context of the screen parameter of visual effect and most of terminal, corresponding first mode arranges the first screen refresh rate, and corresponding the second pattern arranges the second screen refresh rate, and corresponding three-mode arranges the 3rd screen refresh rate; Wherein, described the first interface refresh rate threshold value is less than second contact surface refresh rate threshold value, and described the first screen refresh rate is minimum, and described the 3rd screen refresh rate is the highest; According to the interface refresh rate of current application, the first interface refresh rate threshold value and second contact surface refresh rate threshold decision, go out corresponding which kind of scene, according to different scenes, adjust screen refresh rate.
Concrete, if the interface refresh rate of described current application is less than or equal to described the first interface refresh rate threshold value, corresponding scene mode is first mode, the screen refresh rate of now adjusting described terminal is the first screen refresh rate; If the interface refresh rate of described current application is greater than described the first interface refresh rate threshold value and is less than or equal to described second contact surface refresh rate threshold value, corresponding scene mode is the second pattern, and the screen refresh rate of now adjusting described terminal is the second screen refresh rate; If the interface refresh rate of described current application is greater than described second contact surface refresh rate threshold value, corresponding scene mode is three-mode, and the screen refresh rate of now adjusting described terminal is the 3rd screen refresh rate.
In the embodiment of the present invention, a plurality of interfaces refresh rate threshold value also can be set according to the actual requirements, interface refresh rate is divided into a plurality of segmentations, and a plurality of self-defining scene modes of corresponding a plurality of subsection setup, corresponding each self-defining scene mode arranges different screen refresh rate, according to the interface refresh rate adjustment of current application, adjust the screen refresh rate of described terminal, thus can be flexibly and dynamically adjust the screen refresh rate of terminal, to reach the object of the electric weight of saving terminal.
Further, after adjusting the screen refresh rate of described terminal according to the interface refresh rate of current application, can, according to the mode at setting-up time interval or Event triggered mode, recalculate the interface refresh rate of terminal current application; Then, then according to the interface refresh rate of the current application that recalculates, adjust the screen refresh rate of described terminal, can be in real time and dynamically adjust the screen refresh rate of described terminal.
Further, after adjusting the screen refresh rate of described terminal, according to the screen refresh rate after adjusting, show image.
In the embodiment of the present invention, while receiving screen refresh rate adjustment instruction, the interface refresh rate of computing terminal current application; According to the interface refresh rate of current application, adjust the screen refresh rate of described terminal.So, according to the interface refresh rate of described current application, dynamically adjust the screen refresh rate of described terminal, thereby can reduce the power consumption of described terminal, and then extend the stand-by time of described terminal.

At the interface of current application refresh rate, be less than or equal to the first interface refresh rate threshold value during 5 frame/second, think that the current scene mode of terminal is reading model; At the interface of current application refresh rate, be greater than for first 5 frame/seconds of interface refresh rate threshold value and be less than second contact surface refresh rate threshold value during 20 frame/second, thinking that the current scene mode of terminal is general mode; At the interface of current application refresh rate, be greater than second contact surface refresh rate threshold value during 20 frame/second, think that the current scene mode of terminal is very fast pattern.
In this embodiment mono-, in order to take into account compatible context and the power consumption of the screen parameter of visual effect, most of terminal, under reading model, it was 30 frame/seconds that screen refresh rate is set; Under general mode, it was 45 frame/seconds that screen refresh rate is set; Under very fast pattern, it was 60 frame/seconds that screen refresh rate is set; Mapping relations corresponding to interface refresh rate, scene mode and screen refresh rate are as shown in table 1.
| Interface refresh rate | Scene mode | Screen refresh rate |
| Refresh rate≤5, interface frame/seconds | Reading model | 30 frame/seconds |
| < refresh rate≤20, interface frame/second 5 frame/seconds | General mode | 45 frame/seconds |
| Interface refresh rate > 20 frame/seconds | Very fast pattern | 60 frame/seconds |
