Corresponding to method, function, regulation, subroutine, subprogram etc..
Fig. 1 is a kind of flow chart of frame per second self-adapting regulation method provided by the embodiments of the present application, and the present embodiment is applicable
According to user to the sensitivity of frame per second with environmental change the case where, the scene of adaptive adjustment frame per second, this method can be with
It is executed by frame per second self-adapting adjusting apparatus, wherein the device can generally be integrated in intelligence by software and or hardware realization
In the intelligent terminals such as mobile phone, tablet computer or handheld device.As shown in Figure 1, this method includes：
Step 110 obtains image data to be drawn.
It should be noted that image data is exported by the application program of front stage operation.Assuming that the application program of front stage operation
Frame image data to be drawn is got out, then sends it to CPU, so that CPU judges whether to be drawn certainly by GIFT
Plan.Wherein, GIFT (Graphics Frame Rate Tuner, figure frame per second tuner) passes through the change between judgment frame and frame
How much change amount judges scene for static scene or dynamic scene, to the adjustment frame per second for keeping GPU adaptive.
It (is touched aobvious it should be noted that the application program of front stage operation may be considered the touch screen in intelligent terminal
Display screen) in show application.It would generally be frozen since application program is switched to backstage, it, wouldn't without the drafting of image data
Consider the application program of running background.
It should be noted that image data includes solid information.Wherein, solid information storage is in solid class,
It is the set of dimensions (dim) the different basic configuration such as point (0 dimension), line (1 dimension), face (2 dimension), body (3 dimension).Solid class includes
Two arrays, a storage vertex serial number, another memory topology boundary serial number.Solid can be determined according to solid information
Size, coordinate and shape.
Step 120, according to the corresponding ambient brightness of intelligent terminal, determine the default of each dimension in solid different information
Threshold value.
Inventor has found user in different environments during realizing the application, also not to the susceptibility of frame per second height
It is identical to the greatest extent.For example, in the weaker environment of light, user is less sensitive to frame per second variation, and the requirement to frame per second is also less high.
And in brighter environment, user is more sensitive to frame per second variation, and the requirement to frame per second is also relatively high.Therefore, it can configure
Two groups of different predetermined threshold values increase the frame number of discardable frame data so that predetermined threshold value is turned up under dark situation.It can be to avoid
In the game running that some are drawn using OpenGL/Vulkan, even if user does not touch or picture does not occur especially
Big variation, picture are also still being refreshed with high frame per second, lead to the problem that power consumption is high.
It should be noted that solid different information includes at least following three dimension：Solid variable quantity, displacement and
Amount of zoom.Wherein, solid variable quantity (Geometry), abbreviation G-Value include the variable quantity of solid information, for example, increasing
Add deduct few vertex, and increase or decrease topology boundary etc..Displacement (Motion), abbreviation M-Value, including solid are sat
Target variable quantity.The variation for the size that amount of zoom (Scale), abbreviation S-Value, including solid project in touch display screen
Amount.
It should be noted that predetermined threshold value includes at least following three dimension：Solid variable quantity threshold value, displacement threshold value
With amount of zoom threshold value.For solid variable quantity threshold value, value range 0-1, and value is bigger, indicates user to adjacent two frame
Between solid variable quantity acceptance level it is bigger, current frame data may be more dropped.For displacement threshold value, value
Ranging from 0-1, and value is bigger, indicates that the acceptance level of object movement variable quantity of the user between adjacent two frame is bigger, currently
Frame data may be more dropped.For amount of zoom threshold value, value range 0-1, and value is bigger, indicates user to adjacent two frame
Between article size variable quantity acceptance level it is bigger, current frame data may be more dropped.It illustratively, can be by geometry
Body variable quantity threshold value is denoted as preset first threshold value, and displacement threshold value is denoted as default second threshold, and, amount of zoom threshold value is remembered
To preset third threshold value.
Ambient brightness can be detected by environmental sensor.Intelligent terminal local environment is acquired by environmental sensor
Ambient brightness, and be sent to CPU.The ambient brightness is compared by CPU with predetermined luminance threshold value, if being less than the predetermined luminance
Threshold value, it is determined that intelligent terminal is in dark situation, and dark situation threshold value is selected to draw decision so that GIFT is executed.Wherein, Crape ring
The value of at least one dimension is more than the predetermined threshold value of acquiescence in the threshold value of border.That is, it is assumed that the predetermined threshold value of acquiescence is (i.e. just
In the case of often, such as indoor scene on daytime, night bright light scene etc.) it is G-Value-c threshold values, M-Value-c threshold values and S-
Value-c threshold values.Dark situation threshold value can be G-Value-d threshold values, M-Value-d threshold values and S-Value-d threshold values, and exist
Following at least one relationships：
G-Value-d threshold values>G-Value-c threshold values；
M-Value-d threshold values>M-Value-c threshold values；
S-Value-d threshold values>S-Value-c threshold values.
It is understood that at least one set can be arranged for the predetermined threshold value under dark situation.If a variety of dark situations are arranged
Threshold value is then in advance grouped ambient brightness value under dark situation, associated storage difference brightness value section and dark situation threshold value, real
Existing ambient brightness value is lower, and default dark situation threshold value is higher, and the frame data that can be judged as discarding are more, more power saving.
It should be noted that if detecting that intelligent terminal enters normal brightness environment by dark situation, then by dark situation threshold value
The predetermined threshold value for switching to acquiescence, in order to which GIFT carries out drafting decision according to the predetermined threshold value of the acquiescence.
Step 130, the solid difference for determining the corresponding present image of described image data and adjacent previous frame image
Information adjusts frame per second according to the solid different information and the predetermined threshold value.
Illustratively, CPU reads the solid information that acquired image data includes, and returns to the solid information
One change handles to obtain the second solid parameter.It should be noted that due to according to solid information can determine solid size,
Coordinate and shape.It can be by the target solid of selection preset quantity in image data.For example, can be by player role in game
Solid corresponding with non-player role is labeled as target solid.To which the solid information that reading image data includes can
To be to read the corresponding first solid information of player role and corresponding second solid of non-player role in image data
Information.
By taking the first solid information as an example, illustrate the mode that solid information is normalized.According to more than the first
Vertex information and topology boundary information that body information includes determine the resolution ratio of the corresponding solid of player role, i.e. transverse and longitudinal picture
The quantity of element.By the resolution ratio of the corresponding solid of player role divided by the resolution ratio of the corresponding target image of the image data,
Realize the normalization to solid information G.Similar, vertex information and the topology boundary letter for including according to the first solid information
Breath determines the resolution ratio of the corresponding solid of player role, the i.e. quantity of transverse and longitudinal pixel.By the corresponding solid of player role
The resolution ratio of resolution ratio divided by touch display screen realizes the normalization to scaled data S.Using the lower left corner of touch display screen as
The farthest point of display area in the horizontal is obtained horizontal axis by coordinate origin labeled as 1, and by display area in the longitudinal direction farthest
Point obtains the longitudinal axis labeled as 1.According to the position of the corresponding player role of the first solid information in the target image by the player
Role projects into the corresponding coordinate system of touch display screen, make the coordinate value of the corresponding solid of player role 0 to 1 it
Between, realize the normalization to displacement data M.G, M and S after normalization is denoted as the second solid parameter.
It should be noted that if solid is irregular figure, then longitudinal average length and laterally average length are calculated separately
Degree, and using the longitudinal direction average length as long side, which is short side, builds the interior of the solid of the irregular figure
Connect rectangle.With the resolution ratio of the corresponding solid of resolution ratio game representation player that rectangle is inscribed, using above-mentioned similar fashion
Execute normalization.
It is made the difference using the normalization result of solid information in adjacent two field pictures data, obtains solid variable quantity G-
Value.It is similar, it is made the difference using the normalization result of displacement data in adjacent two field pictures data, obtains displacement M-
Value.It is similar, it is made the difference using the normalization result of scaled data in adjacent two field pictures data, obtains amount of zoom S-
Value.Due to obtaining when the image drawn, system has completed the solid letter for including to adjacent previous frame picture
The normalized of breath, so, it can be joined by obtaining corresponding first solid of the adjacent previous frame picture in preset buffer memory
Number.Wherein, the first solid parameter includes the normalization result of solid information, the normalization result of displacement data and scaling number
According to normalization result.The difference for calculating the second solid parameter and the first solid parameter is believed as solid difference
Breath.
If the numerical value of each dimension of solid different information is respectively less than predetermined threshold value, abandon calling image processing module
The image data for treating drafting is drawn；If at least one in the numerical value of each dimension of solid different information is more than default
Threshold value then calls the image data that image processing module treats drafting to be drawn.Image processing module can be GPU.
If solid variable quantity is less than preset first threshold value, displacement is less than default second threshold and amount of zoom is less than default
Third threshold value then abandons that image processing module is called to draw the image data；Otherwise, described image processing module is called
The image data is drawn.To realize the effect of the frame per second of adjustment image processing module execution Rendering operations in real time.Example
Such as, the application program of front stage operation is sent into GIFT60 frame image datas in upper one second, after rendered decision, GPU is called to carry out
The image data of drafting is 50 frames, i.e. frame per second is reduced to 50fps by 60fps.
Fig. 2 is a kind of schematic diagram of Image Rendering flow provided by the embodiments of the present application.As shown in Fig. 2, front stage operation
Application program prepares frame data to be drawn, when getting out the frame frame data, active push to CPU.It is built-in in CPU
GIFT (Graphics Frame Rate Tuner) module, or increase GIFT modules between CPU and GPU.CPU is called
GIFT modules judge whether the frame data and the solid variable quantity G-Value of adjacent previous frame data are less than default first threshold
Value.If more than preset first threshold value, then GPU is called to draw one according to frame data to be drawn by OpenGL ES API and EGL
Frame target image, GPU send the target image to the video memory of touch display screen (Frame Buffer).If less than default first threshold
Value, then further judge whether the frame data and the displacement M-Value of adjacent previous frame data are less than default second threshold.
If more than default second threshold, then GPU is called to draw a frame according to frame data to be drawn by OpenGL ES API and EGL
Target image, GPU send the target image to the video memory of touch display screen (Frame Buffer).If less than default second threshold
Value, then further judge whether the frame data and the amount of zoom S-Value of adjacent previous frame data are less than default third threshold value.
If more than default third threshold value, then GPU is called to draw a frame according to frame data to be drawn by OpenGL ES API and EGL
Target image, GPU send the target image to the video memory of touch display screen (Frame Buffer).If less than default third threshold
Value, then abandon call GPU the frame data are drawn, that is to say, that abandon the frame data, and control one frame of GPU suspend mode when
Between, to wait for next frame data.Realize that the mode of the time of one frame of suspend mode can be one frame of suspend mode in eglSwapBuffer
Time (waits for 1 vertical synchronizing signal Vsync time).Since the interface realization of eglSwapBuffer is to utilize double buffering
When carrying out Swap, Front Display and Back Surface carry out the address on practical significance and exchange, lower secondary screen brush
When new, the content of Front Display can be shown in touch display screen.The time of one frame of suspend mode in eglSwapBuffer
It is meant that when abandoning a frame data, if detecting Vsync, Swap operations wouldn't be carried out, and when next Vsync arrives,
Swap operations are executed, the address of Front Display and Back Surface are exchanged.Wherein, Back Surface are to draw mesh
Ground, the memory block belonged on Frame Buffer can be regarded as, it is understood that provide for a native window
Display memory block.
It should be noted that android system introduces synchronous (Vsync) flush mechanism during showing refreshing.
Specifically, Vsync flush mechanisms are exactly to be inserted into " heartbeat " i.e. vertical synchronization (Vsync) signal in entire flow for displaying in fact,
CPU is sent to by display controller, is interrupted for generating Vsync, operation and figure layer synthetic operation are drawn to control each figure layer
It is required for completing according to heartbeat.
The technical solution of the present embodiment determines each in solid different information according to the corresponding ambient brightness of intelligent terminal
The predetermined threshold value of a dimension；Determine the solid of the corresponding present image of image data to be drawn and adjacent previous frame image
Different information adjusts frame per second according to solid different information and predetermined threshold value.It is dynamic by ambient brightness using above-mentioned technical proposal
State adjusts predetermined threshold value, can improve the predetermined threshold value under dark situation, is further reduced and is sent to image processing module and is rendered
Frame data amount, to achieve the effect that reduce power consumption.
Fig. 3 is the flow chart of another frame per second self-adapting regulation method provided by the embodiments of the present application.As shown in figure 3, should
Method includes：
The application identities of step 301, the application program of acquisition front stage operation.
Wherein, application identities are the unique marks of application program a difference and other application program, for example, application identities
Can be using packet name or process name etc..
It is detecting application program launching, and in front stage operation, is obtaining the packet name or process name of the application program.
Step 302 judges whether the application program belongs to default white list according to the application identities, if so, holding
Otherwise row step 303 executes step 311.
It should be noted that default white list is used to store the application program for needing by GIFT draw decision, with
Control is avoided showing the picture of intelligent terminal and is produced bigger effect by the scope of application of frame per second adjustment mode reducing power consumption.If
It inquires the application program being currently up and belongs to default white list, it is determined that need to judge application program output by GIFT
Frame data are dropped or are drawn, and otherwise, GPU are called to draw the frame data of application program output.It can also be by pre-
If white list stores solid variable quantity threshold value, displacement threshold value, amount of zoom threshold value and whether carries out touch judgement (for example, can
With preset different ident value T-Value indicate whether to carry out touch judgement) etc. parameters.
Illustratively, it when application program launching, is inquired according to the application identities and presets white list, to determine the need for
Judge that the frame data of application program output are dropped or are drawn by GIFT.
It is understood that if application program is not belonging to default white list, image processing module is called to use default frame
Rate draws it.Wherein, acquiescence frame per second can be by reading in the configuration file of the application program.
It should be noted that default white list can be sieved by vendor server according to the history usage record of user
Choosing, and push to intelligent terminal after intelligent terminal networking.The screening criteria of default white list includes：The energy saving ratio of static scene
More than 10%；And under dynamic scene (such as touching, scene switching), no interim card situation etc..For example, by application shop
The application program (such as the ranking list etc. being ranked up according to download time) for selecting preceding setting quantity in ranking list, according to
Above-mentioned screening criteria carries out sieve series, sieve series result is added to default white list, and push to user terminal online.If presetting white name
Singly there is update, first push update notification to intelligent terminal, to prompt user to download updated default white list.If updated
Default white list is downloaded success, then updated default white list updating locally default white list may be used.
Step 303 determines whether the application program needs to carry out touch judgement according to the default white list, if so,
304 are thened follow the steps, otherwise, executes step 306.
Illustratively, it in application program launching, is inquired according to the application program identification and presets white list.If this applies journey
Sequence belongs to default white list, then reads the ident value of touch detection mark.It needs to carry out touch detection if the ident value is representative
Value, then follow the steps 304.If the ident value is the value that representative need not carry out touch detection, the default threshold of acquiescence is selected
Value executes step 306.
Step 304, detection touch event, and when the touch event is triggered by touch screen, obtain intelligent terminal and correspond to
Ambient brightness.
Illustratively, if necessary to carry out touch detection, then touch operation is being detected and the touch operation is by touch screen
When triggering, the ambient brightness in intelligent terminal local environment is read by environmental sensor.
It should be noted that user inputs touch operation for the application program of front stage operation to intelligent terminal, intelligence is eventually
End touch event is triggered by the touch operation detected.Touch operation includes but not limited to the touch behaviour acted on touch screen
Make, and, the touch operation detected by body-sensing technology.It, can be with it follows that touch event can be triggered by touch screen
It is triggered by preset body-sensing detection sensor.In some scenarios, intelligent terminal can be with simulated touch event, by the simulation
Touch event is exported to application program, to control the corresponding operation of touch event that application program executes the simulation.For example, with
Family needs intelligent terminal away from keyboard but is not desired to terminate game, on-hook function can be arranged for some reason during playing game,
Use the technology of the operation of setting program analog subscriber in gaming.
If detecting, touch screen driving reports key information, or detects the voltage change situation of touch screen, it is determined that
Touch event is triggered by touch screen.
Optionally, can be the default mark of subject definition of triggering touch event in advance.It is by touch screen in touch event
On give the correct time, for the touch event add screen triggering mark.In touch event by giving the correct time in preset body-sensing detection sensor, for this
Touch event adds body-sensing triggering mark.When touch event is triggered by modeling event, simulation triggering is added for the touch event
Mark.To by inquiring default mark, it may be determined that whether touch event is triggered by touch screen.
