Picture complexity is represented with the color range distribution situation of the pixel included with image.
Step 130, the resolution ratio that the application program is dynamically adjusted according to the picture complexity.
In the embodiment of the present invention, resolution ratio can refer to the precision of screen picture, the number of the pixel that screen can show.
Because the point on screen, line and face are all made up of pixel, displayable pixel is more, and picture is finer, same screen
The information that curtain region interior energy shows is also more, can also embody more rich details, makes display picture finer and smoother.But also can be because
This needs to consume more resources, more internal memories, bigger memory space etc., Caton phenomenon easily occurs, also makes the work(of terminal
Consumption is higher.And relatively low resolution ratio can then make display picture rougher, image is especially enlarged into a large-size and is shown
When (such as when transverse screen shows in the terminal etc.), display effect can be caused not ideal.Can be according to the picture of application program
Complexity enters Mobile state adjustment to resolution ratio, such as when picture complexity is smaller, can suitably reduce resolution ratio.And for example, respectively
For transverse screen or the reference resolution ratio of portrait layout Game Setting multiple grades.The original resolution with reference to resolution ratio less than application program

It is the default setting resolution ratio of each application program in white list, during application program launching in the white list, according to
The setting resolution adjustment original resolution.Wherein, original resolution of the setting resolution ratio less than application program.It is default one
Less resolution ratio can realize reducing the effect of power consumption.If the resolution ratio after adjustment ensure that picture has preferably display
Effect, then without being changed to resolution ratio, if picture display effect is poor, can again increase the resolution ratio of application program.
In order to make it easy to understand, below by taking android system as an example, it is aobvious from being generated to display picture in android system
The process shown carries out simple illustration.Fig. 1 b are a kind of display process schematic provided in an embodiment of the present invention.
First, applying (Application) layer, each application program (hereinafter referred to as using or APP) includes 1 or many
Individual figure layer, each (is typically determined according to the application design conditions of oneself using APP1, APP2 ... APPN by corresponding installation kit APK
It is fixed) each individually execution figure layer draws (Render) operation (drawing the image in figure layer), and operate treatment to complete drawing
Afterwards, the All Layers that will be drawn respectively are applied to be sent to the figure layer synthesis module (Surface for performing figure layer synthetic operation
flinger)。
Then, in application framework (Framework) layer, All Layers (including visible layer and invisible figure layer) composition one
Individual the layers list, is defined as ListAll.Figure layer synthesis module picks out visible layer composition visible layer row from ListAll
Table, is defined as DisplayList.Then, figure layer synthesis module three frame buffer (Frame that can be recycled from system
Buffer, abbreviation BF or buffer) in, the FB of free time is found out, and on the idle FB, according to application configuration information,
For example which figure layer should bottom set, which figure layer should top set, which region be that visual field and which region are clear area etc.
Deng, being operated by synthesizing (Compose), the map overlay that will be included in DisplayList together, obtains final to be shown
Picture.
Finally, in kernel (Kernel) layer, can by picture transmission to be shown to viewing hardware (including display controller and
Display screen, makes picture to be shown be eventually displayed on display screen.Here the type to display screen is not limited, for example, can be liquid
Crystal display (Liquid Crystal Display, LCD).
In addition, android system introduces synchronization (Vsync) flush mechanism during refreshing is shown.Fig. 1 c are this
The Vsync that inventive embodiments are provided shows the schematic diagram of flush mechanism.Specifically, Vsync flush mechanisms are exactly in fact whole
In flow for displaying, insertion " heartbeat " is system synchronization (Vsync) signal, CPU is sent to by display controller, for producing
Vsync is interrupted, and to control, each figure layer draws operation and figure layer synthetic operation is required for being completed according to heartbeat, so that will be whole
Committed step during display all brings the unified management mechanism of Vsync into.The frequency of Vsync signals is common at present to be
60Hz.As illustrated in figure 1 c, it is assumed that the Vsync signal periods are T, and the transmission delay of signal, first Vsync signal are not considered
After Vsync1 reaches CPU, CPU forwards first Vsync signal Vsync1 to each application, and each application response user is in display screen
On touch slide etc. operation, start perform draw operation；After each application completes to draw operation, obtain what each application was drawn
Multiple figure layers.After second Vsync signals Vsync2 reaches CPU, CPU forwards second Vsync to believe to figure layer synthesis module
Number Vsync2, figure layer synthesis module starts to perform figure layer synthetic operation, applies the multiple figure layers drawn to be synthesized by each, raw
Into picture to be shown.After 3rd Vsync signals Vsync3 reaches CPU, system starts to perform display refreshing, and this is to be shown
Picture is eventually displayed on display screen.Seen from the above description, application program, figure layer synthesis module and display screen are received
The frequency of Vsync signals is consistent, and is the fixed value for pre-setting.
In the flow that mobile terminal figure layer is drawn, synthesis and refreshing show, there are 3 kinds of frame per second：Draw frame per second, synthetic frame
Rate and refresh rate.
Wherein, draw after frame per second completes for figure layer, triggering figure layer synthesis module carries out the frame per second of figure layer synthesis, can be with
It is interpreted as the figure layer frame number of unit interval (for example, 1 second) drafting.The drafting frame per second for drawing frame per second including application program and
The drafting frame per second of figure layer.The application program run in system may have multiple, and each application program potentially includes multiple figure layers, example
Such as, three figure layers are generally comprised under video player application：One figure layer of display video content, may be defined as U1；Two
The figure layer of individual SurfaceView types, one is used to show barrage content, may be defined as U2, and another is used to show user circle
Face (User Interface, UI) control (such as playing progress bar, volume control strip and various control buttons) and advertisement, can
It is defined as U3.The drafting frame per second of the application program is that the number of times for drawing operation is performed in the application program unit interval, wherein, hold
Row may depict one or more figure layer when once drawing operation.The drafting frame per second of the figure layer is same numbering or title
Be triggered the number of times of drafting in the figure layer unit interval of (such as U1, U2 or U3 above).
Synthesis frame per second is that the figure layer that each application program is drawn is synthesized a frame per second for picture to be shown, it is possible to understand that
It is the picture frame number of unit time synthesis.
Refresh rate is the frame per second of mobile terminal display screen picture refreshing.Typically, display screen can be refreshed with the refresh rate of 60Hz.
The frequency of the reference signal (such as Vsync signals) of figure layer, synthesis figure layer or screen-refresh can be used to draw by reduction
Rate come realize reduce figure layer draw frame per second, reduce figure layer synthesis frame per second or reduce screen refresh rate, and draw figure layer, synthesis figure layer
The frequency of Vsync signals corresponding with screen-refresh can with identical (being such as reduced to 50Hz by 60Hz) can also it is different (such as
50Hz, 52Hz and 54Hz are reduced to by 60Hz respectively).Also operation, figure layer synthetic operation and screen brush can be drawn by changing figure layer
Newly operate to the response mechanism of reference signal to realize that reducing figure layer draws frame per second, reduces figure layer synthesis frame per second or reduce screen brush
New rate.For example, the 2n+1 signal for receiving is responded, the 2n signal for receiving is not responding to；And for example, with n (such as 5)
Signal is one group, and the signal of the first kind preset numbers (such as 1,2,4,5) in every group is responded, Equations of The Second Kind preset numbers (such as 4)
Signal is not responding to.
Reducing display picture resolution ratio can draw stage or figure layer synthesis phase to realize in figure layer, such as application program
The resolution ratio of image is reduced when figure layer is drawn, and for example figure layer synthesis module can turn down the resolution ratio of figure layer before being synthesized
Or turn down the resolution ratio of picture to be shown in figure layer building-up process, wherein, turning down resolution ratio can be by image procossing phase
Pass means are realized.

In the embodiment of the present invention, the picture complexity of application program according to time span set in advance, can be repeatedly determined.
Default complexity can be the maximum of picture complexity when the current resolution ratio for setting can ensure that picture display effect is good
Value, or the arbitrary value that the maximum can also be no more than.When the picture complexity of application program exceedes default complexity,
Illustrate that the possible content of currently displaying picture of application program is more complicated, details is more, and the resolution ratio of current setting cannot ensure picture
The display effect in face, it is possible to the problems such as picture is unintelligible occurs.The threshold value of number of times can be set according to degree of regulation,
Threshold value is bigger, then illustrate that the condition of adjustment is stricter, can more accurately judge whether to need to adjust resolution ratio, but also have can
The overlong time that can be judged, and resolution ratio cannot be adjusted in time.Therefore threshold value can be set according to the actual requirements.
When the picture complexity exceedes the number of times of default complexity more than given threshold in setting time length, then by application program
Resolution adjustment be former resolution ratio, to ensure the display quality of picture.If not less than the current of maintenance application program is divided
Resolution is constant.
For example, belong to default white list in the application program for detecting current operation, and the application program picture number
It is 13 to 240 (interval i.e. beyond the 3rd picture complexity) according to tonal gradation scope in corresponding grey level histogram, and each is grey
When the corresponding pixel count of degree grade is no less than 10, start timer, timing setting time span.Judge the setting time length
Interior, whether the tonal gradation of the sectional drawing of the application program exceedes given threshold beyond the interval number of times of the 3rd picture complexity.If
It is that the resolution ratio of the application program is then reverted into former resolution ratio (i.e. original resolution) by current reference resolution ratio.Otherwise,
Maintain the current resolution ratio of application program constant.
The embodiment of the present invention by judge picture complexity in setting time length exceed default complexity number of times whether
More than given threshold, it is determined whether need to be adjusted resolution ratio, repeatedly complexity is judged, the standard of judgement is improve
Exactness.When picture complexity exceedes the number of times of default complexity more than given threshold in setting time length, then by current resolution
Rate reverts to the original resolution of the application program, is required with meeting display；Otherwise, the current of the application program is not adjusted to divide
Resolution, to realize reducing power consumption.The effect taken into account display effect and reduce power consumption is reached, the cruising time of terminal is improve.

Number, is the interval corresponding resolution ratio of the picture complexity by the resolution adjustment of application program.Picture complexity is closed with resolution ratio
System similar to stepped corresponding relation, picture complexity is higher, then may determine that picture it is finer, it is necessary to display details more
It is many, then by resolution adjustment to bigger.And the change of picture complexity within the specific limits when, it is believed that should in the range of picture
The amplitude of variation of complexity is smaller, then resolution ratio can be kept constant, to reduce the workload of resolution adjustment.
Exemplary, if the picture complexity of the application program is in the picture complexity of setting is interval, according to pre-
Piecewise function (piecewise function i.e. Fig. 6 shown in) of the resolution ratio for first setting on picture complexity, by the application program
Resolution adjustment is the interval corresponding resolution ratio of the picture complexity.According to resolution ratio set in advance on picture complexity
Piecewise function, the resolution ratio to application program is adjusted, and makes the adjustment of resolution ratio more convenient.
