Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Be provided with application program in intelligent terminal, application program, in operational process, needs the electric energy using battery to provide.In order to reduce application program expending battery electric quantity, the functional module that in application program, some is of little use can be closed by force, even directly can be closed when application program does not use for a long time.But, poor with the experience that upper type brings to user, for this reason, the invention provides the control method of application program picture refreshing, when ensureing that application program is normally run, by improvement application program picture refreshing process, realizing object of economizing on electricity.
It should be noted that, application program, in operational process, can generate picture according to certain refresh rate, and is presented on the display screen of intelligent terminal according to this refresh rate by the program picture of generation.Wherein, picture refers to the program picture that application program needs to be shown to user, and picture is drawn out one by one, also shows one by one during display, when the speed of display frame is after to a certain degree, user just can watch smooth picture on a display screen.The speed of display frame can represent with refresh rate, and the refresh rate of some application program is higher, like this, will draw comparatively continually and display frame, thus the electricity used is just more.But inventor is found by research, for user, suitably reduces refresh rate, its viewing experience indifference.Therefore, invention thought of the present invention suitably reduces the drafting of application program picture and the speed of display, reaches and reduce expending of electricity.
See Fig. 1, it illustrates the flow process of the control method of the application program picture refreshing that the embodiment of the present invention provides, specifically comprise two aspects: be i.e. pattern drafting control procedure and picture display and control process.
Wherein, pattern drafting control procedure comprises the following steps:
Step S101: when receiving the drafting instruction that application program sends to pattern drafting interface, judges whether described drafting instruction meets and presets drafting condition, preset drafting condition, perform step S102 if meet; If do not meet and preset drafting condition, return step S101.This control method is used for the refresh rate of controlling application program picture, it should be noted that, application program is in operational process, when needing to show a frame picture on a display screen, first can send to pattern drafting interface and draw instruction, it should be noted that, application program sends the frequency of drawing instruction and sends according to refresh rate, namely whenever needs refreshing one frame picture, then send to pattern drafting interface and draw instruction.
The present embodiment can intercept and capture drafting instruction, specifically, the drafting instruction that application program sends can not directly call drafting interface, but be first sent to the execution module of the present embodiment, therefore, execution module can receive the drafting instruction that application program sends, when receiving drafting instruction, judge whether this drafting instruction meets default drafting condition immediately, if meet, then perform calling of follow-up drafting interface.If do not meet, then need to return step S101, the next one that wait-receiving mode application program sends again draws instruction.
As can be seen from this step, preset drafting condition and be used for controlling the need of drafting present frame picture, if required, draw, otherwise, again monitor the drafting instruction of next frame, namely abandon the drafting of this frame picture, alternatively, skip the drafting of this frame picture.
It should be noted that, what the present embodiment adopted is the drafting instruction receiving application program transmission passively, namely draws instruction whenever receiving one, then performs a step S101, be not the drafting instruction that real-time listening application program sends, which save and monitor the electricity that causes and expend.
Step S102: trigger pattern drafting interface described in described application call, to obtain the picture of drafting, and returns step S101.
Wherein, the process triggering application call pattern drafting interface can be send order to application program, after application program receives this order, namely calls pattern drafting interface; Can also be arrange zone bit, application program can monitor this zone bit, when this zone bit is certain preset value, then can call pattern drafting interface.Call pattern drafting interface to generate the current program picture needing display, the picture of generation is waited for and being shown.
Wherein: picture display and control process comprises the following steps:
Step S201: when receiving the idsplay order that described application program sends to picture display interface, judges whether described idsplay order meets and presets display condition, preset display condition, perform step S202 if meet; If do not meet and preset drafting condition, return step S201.
Step S202: trigger picture display interface described in described application call, to show the picture of described drafting, and returns step S201.
Application program after sending pattern drafting instruction to application program, can send idsplay order to picture display interface, it should be noted that, the frequency that application program sends idsplay order is identical with drafting instruction, namely all sends according to refresh rate.Monitor this picture display interface, when listening to idsplay order, with above-mentioned pattern drafting method in like manner, judge whether this idsplay order meets display condition, satisfied, the picture that display is drawn, otherwise, again monitor the next idsplay order that application program sends.Visible, the idsplay order of a part can be left in the basket, although namely have idsplay order, does not go to call display interface and goes display frame, can avoid calling the electricity that display interface causes and expend.
It should be noted that, above-mentioned pattern drafting control procedure and picture display and control process are independently, but both are non-fully onrelevant also, the picture that the former draws can be presented on screen by the latter, more specifically, often draws a two field picture, then can show this two field picture of drafting, both avoided drawing unnecessary picture and caused the wasting of resources, and avoided again drawing and cause picture imperfect not in time, affect Consumer's Experience.Can reach the setting based on application program self of such effect, namely application program self can send respectively successively and draw instruction and idsplay order, and transmission frequency identical (sending according to refresh rate).Therefore, above-mentioned default drafting condition needs identical with default display condition, and like this, whenever drafting instruction is eligible, when drawing a two field picture, now, idsplay order also can be eligible, thus show this two field picture of drafting immediately.It should be noted that, drafting condition and display condition need to control at zone of reasonableness, make the refresh rate of picture in certain scope, as the numerical value within the scope of 20 frames per second to 30 frames per second, to ensure the viewing experience of user.
From above technical scheme, the control method of the application program picture refreshing that the present embodiment provides, comprise the control procedure of pattern drafting and the control procedure of picture display, reduce respectively and generate the speed of picture and the speed of display frame, in other words, decrease drafting and the display number of times of application program picture in the unit interval respectively, save battery electric quantity, reduce equipment power dissipation.
It should be noted that, above-mentioned application program can be various game application, browser etc., but be not limited to this, can be the application program that other various needs frequently use OpenGLES/EGL technology to drawing picture, namely refresh rate exceedes the application program of predetermined threshold value.
It should be noted that, each in above-described embodiment returns all non-actual action performed, just in order to show the arrival again waiting for next instruction.And, in above-described embodiment, can each return step time, return cue to application program, send successfully with prompting application program instruction, particularly, the cue returned in pattern drafting control procedure, prompting be application program draw instruction send successfully, the cue returned in picture display and control process, prompting be that application program idsplay order sends successfully.
The mode utilizing drafting condition to control drawing process can be the following scheme provided.See shown in Fig. 2 A, it illustrates the control flow of pattern drafting process, specifically comprise:
Step S301: when receiving the drafting instruction that application program sends to pattern drafting interface, judges whether the first default counting mark identifies identical with the first predetermined number, if so, performs step S302; Otherwise, perform step S304.
As can be seen from following step S303 and step S304, default counting is identified at continuous change, namely whenever drafting one subframe, then reinitializes counting mark, when skipping once drafting instruction, then counting mark is upgraded.So, judge whether counting mark identifies identical with predetermined number, if identical, then represent that needs call and draw interface to draw picture.It should be noted that, this predetermined number mark is corresponding with the refresh rate that will change.As needed that the refresh rate of 60 frames per second original for application program is reduced to 20 frames, and be all initialized as 0 during each initialization, then this predetermined number is designated 2, and namely every 3 drafting instructions are just called and once drawn interface generation picture.
Step S302: trigger pattern drafting interface described in described application call.
Step S303: counting mark is preset in initialization first, and returns step S301.
Wherein, be previously provided with counting mark, be equivalent to a counter.This count flag has initial value, as being 0.When application call pattern drafting interface generates a frame picture, need to reinitialize this count flag, as being re-set as 0.
Step S304: upgrade described first and preset counting mark, and return execution step S301.
Wherein, upgrade first and preset counting mark, draw instruction with this time that records application program sends.Alternatively, update mode is: preset count flag by first and add 1.
It should be noted that, other steps in Fig. 2 A see above-mentioned explanation, can not repeat herein.In addition, step S303 can perform with the process returning step S301 simultaneously, or the former performs after the latter.In like manner, step S304 can perform with the process returning step S301 simultaneously, or the former performs after the latter.
The mode utilizing display condition to control procedure for displaying can be the following scheme provided.See shown in Fig. 2 B, it illustrates the control flow of picture procedure for displaying, specifically comprise:
Step S401: when receiving the idsplay order that described application program sends to picture display interface, judges.Whether second presets counting mark identifies identical with the second predetermined number, if so, performs step S402; Otherwise, perform step S404.
Step S402: trigger picture display interface described in described application call.
Step S403: counting mark is preset in initialization second, and returns step S401.
Step S404: upgrade described second and preset counting mark, and return step S401.
Wherein, the control thought of procedure for displaying is identical with the control thought of drawing process, and therefore, the step in Fig. 2 B illustrates and see the above-mentioned explanation about Fig. 2 A, can not repeat.
Need to illustrate, above-mentioned pattern drafting interface is specially OpenGLES interface, and picture display interface is specially EGL interface.The interface for drawing picture that the former provides for Android system, the latter is the interface for display frame.Can think, the former draws picture on drawing board, and the picture on this drawing board is presented on screen by the latter.
It should be noted that, the invention thought of each embodiment above-mentioned is to skip drafting request and the display request of some frames, thus reduces the refresh rate of picture.Based on same invention thought, further embodiment of this invention provides the control method of application program picture refreshing, describes in detail below to the method.The method comprises pattern drafting control procedure and picture display and control process equally.

Step S602: judge whether described vertical synchronizing signal meets and preset display condition, preset display condition if meet, perform step S603, preset display condition if do not meet, return step S601.
Step S603: trigger picture display interface described in described application call, and return step S601.
It should be noted that, vertical synchronizing signal is bottom hardware CMOS macro cell or the simulation generation also outwards transmission of smart machine, the picture drawn in order to synchronous modules.Particularly, each drafting module is all after listening to this signal, just starts to draw picture.That is, this vertical synchronizing signal is synchronizing signal, is specially Vsync (Vertical synchronization, vertical sync pulse) signal.
In addition, judge whether in the present embodiment to meet default drafting condition and judge whether that meeting the method presetting display condition with reference to above, can not repeat herein.
Due to when the picture of display application program, may the content of not only display application program picture, also need a part of system interface that display system is drawn, as frame etc., that is, need the picture splicing picture of application program drafting and other modules drawn to be complete picture, be presented on screen.Use this synchronizing signal as the foundation judging whether to draw picture and generate picture as judgement in the embodiment of the present invention, object makes the picture synchronization that in the picture of drafting and equipment, other modules are drawn.
Visible, utilize vertical synchronizing signal to the control of refresh rate, can realize reducing on the basis of refresh rate, simultaneously synchronous with the drawing process of other modules, avoid film flicker, the picture of display be more stable, improves Consumer's Experience.
