Deng.Wherein, owing to mobile terminal has portability, the game on mobile terminal can be played whenever and wherever possible,
Therefore the most substituted traditional PC (personal computer, PC) of the game on mobile terminal
The trend of end game, becomes the first-selection of people's amusement and recreation.
In order to ensure the quality of game of mobile terminal, in the development process of game of mobile terminal, it is right to need
Game of mobile terminal carries out the test of each side.Wherein, the test to the refresh rate of screen-picture change is
One important test parameter.The refresh rate of screen-picture change is for representing the change of mobile terminal screen
Frequency, represents with transmission frame number per second (Frames Per Second, FPS), wherein a frame represents one
Secondary still image.FPS is the term converted from motion picture technique, and people see in movie screen
The still image that is actually continuously shot by several of dynamic image play continuously and formed.Due to people
The special physiological structure of eye, if the frame per second of picture is more than 24, i.e. FPS > 24, people just will be considered that
The picture seen is coherent, and this phenomenon is referred to as persistence of vision.
But, in computer realm, several still images of composition dynamic image are to be calculated by processor
Out rather than as cinematographic field being actual photographed goes out.Therefore, in computer realm, often
One frame only includes the information of a time point.And in cinematographic field, each frame may include a time
Content in Duan.So, in the dynamic image of computer disposal, need to use higher frame per second,
Image player can be made more smooth.
In the terminal, the process of frame refreshing uses " double buffering " technology, be divided into Back Buffer (after
Platform buffers) and Front Buffer (foreground buffering).Back Buffer is the caching that processor is directly drawn
Data, Front Buffer is the image that user is seen on mobile terminal display screen.Image is first at Back
Drawing in Buffer, processor processes Back Buffer, then exchanges with Front Buffer, is rendered into display
In equipment, then, the number of times rendered per second is exactly frame per second.But, in game of mobile terminal engine,
It is some application programming interfaces (Application Programming Interface, API) by engine
In Back Buffer, draw picture material, a picture includes multiple material.Engine uses a certain tune
With instruction, the picture material drawn in Back Buffer is rendered in Front Buffer, now mobile whole
In end display screen, the picture of display will change.But the material being now rendered in Front Buffer may not
It is a complete frame, but the portion material in a frame.It is to say, in the terminal, a frame is drawn
The display screen that face is possible corresponding more than twice refreshes.
Image procossing characteristic based on mobile terminal, uses FPS as the refresh rate changing screen-picture
Test parameter, possibly cannot embody the actual refresh rate of screen, thus the survey that impact is to game performance
Examination accuracy.

Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The all other embodiments obtained, broadly fall into the scope of protection of the invention.
Along with the development of computer technology, the performance of mobile terminal is increasingly stronger, in some mobile terminals
Also add Graphics Processing Unit (Graphics Processing Unit, GPU), to strengthen mobile terminal
Image-capable.This makes it possible to run a lot of large-scale application software in the terminal, including
Various types of games.Wherein type of play is divided into multiple, and such as Role Playing Game, first person is penetrated
Hit game, action game, car race game, riddle game, card games etc..Wherein shooting game,
The game of the kind such as action game, car race game, picture change frequency is quickly, then mean that these are swum
The user that play needs the refresh rate of higher screen-picture change that object for appreciation can be made to play obtains good game
Experience.Picture change frequency, for one is played, is a very important parameter, permissible with it
Judge to play the most smooth.For scene changes game quickly, need to improve picture change frequency and come
Strengthen and experience；And for the little game of some card class scene changes, need to reduce picture change frequency
Reduce battery consumption.The most a lot of game of mobile terminal all makes dynamic picture change frequency,
Fight interface, promotes picture change frequency, to improve fight experience, at non-fight interface, then reduces picture
Face change frequency, reduces electric quantity consumption.
But owing to, in mobile terminal, the process of frame refreshing uses " double buffering " technology, among a frame,
Screen may refresh once or more, tests game of mobile terminal only with current FPS parameter
Screen-picture change refresh rate, cannot truly reflect the true refresh rate of mobile terminal screen, lead
Cause the test existing defects to game of mobile terminal, and then the game experiencing of user may be affected.
The embodiment of the present invention provides the refresh rate method of testing of a kind of game of mobile terminal screen-picture change,
By the actual change situation of mobile terminal screen is detected, thus obtain can truly reflecting movement
The parameter of the refresh rate of terminal screen picture change.
In embodiments of the present invention, mobile terminal can be the portable mobile termianl such as mobile phone, panel computer.
The refresh rate test side of the game of mobile terminal screen-picture change that Fig. 1 provides for the embodiment of the present invention
The flow chart of method embodiment one, as it is shown in figure 1, the method for the present embodiment includes:
Step S101, the game screen color data change of monitoring mobile terminal.
Specifically, embodiments provide a kind of method of testing to game of mobile terminal, its test
Purpose is that the refresh rate of the change of the game screen picture to mobile terminal is tested.So firstly, it is necessary to
Run on mobile terminals and need the game process of test.
Owing to the frame refreshing of mobile terminal uses " double buffering " technology, i.e. first by CPU
(Central Processing Unit, CPU) or the direct drawing data of GPU are also stored in Back Buffer
In, i.e. in caching.Generally, due to a two field picture is made up of multiple materials, CPU or GPU needs
To draw each material by several times, and the material data after drawing is stored in Back Buffer.When a frame figure
All materials of picture are the most drawn when completing, and CPU processes the data in Back Buffer, and and Front
Buffer exchanges, and is rendered in screen, thus completes the refreshing to screen.But it is as mobile terminal trip
Increasing of play picture complexity, the material quantity comprised in a two field picture gets more and more, and CPU may be one
When all material data of two field picture do not have drawn completing, just trigger from Back Buffer to Front
The data exchange of Buffer, refreshes display screen.It is to say, in the drawn mistake of a two field picture
Cheng Zhong, may carry out the refreshing of more than twice to screen.
In order to reflect the actual refresh rate of game of mobile terminal, can be to the game screen picture of mobile terminal
It is monitored, when the game screen picture color data of mobile terminal are changed, i.e. thinks mobile whole
End game is refreshed.The refresh rate i.e. using the change of game of mobile terminal screen-picture substitutes frame per second.
It should be noted that the game process run on mobile terminals is probably full screen display, it is possible to
Can only subregion at mobile terminal screen show, therefore when mobile terminal is monitored,
It is that the game screen picture to mobile terminal is monitored rather than carries out the whole screen of mobile terminal
Monitoring, so can reflect mobile terminal true refresh rate of screen when running game process.Right
The concrete grammar that the game screen picture of mobile terminal is monitored has multiple, will enter in the following embodiments
Row describes in detail.
Step S102, there is the timestamp information of change every time in record color data.
Specifically, when the game screen picture of mobile terminal is monitored, when each mobile terminal is swum
When change occurs in play screen-picture color data, there is the time of change, and will save as to go out every time in record
Now change the timestamp of correspondence.This process is equivalent to set up the timestamp of a game screen picture change
Sequence, such as, can be designated as sequence T, T={t0, t1, t2 ..., t (n-1), t (n) }.Wherein t0
For initial time stamp, game of mobile terminal screen-picture transformation period for the first time is the t1 moment.
Step S103, calculates the number of times of color data change in Preset Time window, obtains mobile terminal
Game screen picture change refresh rate.
Specifically, being currently used for representing parameter FPS of screen change frequency, its definition is transmission frame per second
Number, the quantity of the frame being transferred on display screen the most per second.And in the present embodiment, record is mobile whole
There is the number of times of change in the game screen picture color data of end, therefore can move in Preset Time window
There is the number of times of change as the trip for reacting mobile terminal in the game screen picture color data of dynamic terminal
The parameter of play screen-picture change frequency, is referred to as the refreshing of the game screen picture change of mobile terminal
Rate.This Preset Time window can be arbitrary time span, but, usually, being used to according to this area
With design, this Preset Time window could be arranged to 1 second, and the game screen picture i.e. calculating mobile terminal exists
The change frequency occurred in one second, obtains the game screen picture of the mobile terminal refresh rate in 1 second,
It is designated as refresh rate per second (Refresh Pre Second, RPS).Game screen due to mobile terminal
Picture there may be the refreshing of more than twice in a frame picture, and the reaction of this refresh rate is mobile terminal
The actual change number of times of game screen picture, therefore, use this refresh rate to represent the trip of mobile terminal
The change frequency of play screen-picture, it is possible to truly reflect the change feelings of the game screen picture of mobile terminal
Condition, than using, FPS parameter is more accurate.
In sum, the refresh rate test side of the game of mobile terminal screen-picture change that the present embodiment provides
Method, by the change of the game screen picture color data of monitoring mobile terminal, and records this color data
The timestamp information of change occur, the screen calculating mobile terminal according to this timestamp information is being preset every time
Change frequency in time window, obtains the refresh rate of the game screen picture change of mobile terminal, due to this
What refresh rate reacted is the actual change number of times of game of mobile terminal screen-picture, therefore, uses screen to draw
The refresh rate of face change represents the change frequency of game of mobile terminal screen-picture, it is possible to truly reflect
The situation of change of the game screen picture of mobile terminal, assists the game screen picture to mobile terminal to change
Situation is accurately tested.
Conventional design based on this area, the following each embodiment of the present invention is all 1 second to be with Preset Time window
The game screen picture refreshing rate of example, i.e. game of mobile terminal is to illustrate as a example by RPS, but the present invention
The refresh rate method of testing of the game of mobile terminal screen-picture change provided is not limited.
During running due to game of mobile terminal process, screen-picture complexity sometimes is sometimes simple, and
When screen-picture is more complicated, potentially include more material, need when it is calculated by CPU and GPU
Consume more resource, now may cause the decline of refresh rate.And relatively simple at screen-picture, bag
When the material that contains is less, then may not have the problems referred to above.It is to say, the game screen of mobile terminal
The refresh rate of curtain picture change dynamically changes such as the change of picture.So to mobile terminal
During game screen picture refreshing rate is tested, only the refresh rate of a time period is tested,
Possibly cannot reflect game of mobile terminal running state of a process.Therefore it is generally required to carry out continuance test,
I.e. in game process running, persistently refresh rate is tested.
Therefore, it can first define a testing time section to the game screen picture refreshing rate of mobile terminal,
This testing time section can be a time period preset, it is also possible to be the overall process of game process operation.
In this testing time section, every default test period, just calculate the screen of a game of mobile terminal
Picture color data change frequency in Preset Time window.As a example by Preset Time window is 1 second, the most just
It is every a default test period, just calculates the screen-picture color data of game of mobile terminal 1
Change frequency in Miao, so can obtain the sequence of the game screen picture refreshing rate of a mobile terminal,
This sequence illustrates the refresh rate variation tendency in game of mobile terminal process running.According to this sequence
Can find out in game of mobile terminal process running, when refresh rate is undergoing mutation intuitively, test
Personnel can carry out corresponding debugging process to game.This test period preset can be one and arbitrarily set
The value put, it is the shortest that default test period is arranged, then the degree of accuracy of test will be the highest.Usually,
The highest frame per second run at present due to mobile terminal is mostly about 60 frames, and therefore this test period at least needs
It is less than 1/60 second, the most about 16 milliseconds.Alternatively, it is also possible to screen-picture color data change frequency
Arranging this test period for unit, screen-picture color data changes and once tests such as every time,
Or do not have twice screen-picture color data to change to carry out once test etc..
Consider further that during the refresh rate test that game of mobile terminal screen-picture is changed, may
The process that test suspends occurs, or causes game owing to mobile terminal or game process itself break down
Process long period card.Now tester can know test occur suspend, or have been able to from
Appearance card is substantially observed, then the most again to mobile terminal screen on the screen of mobile terminal
The refresh rate of curtain carries out test and has been out meaning.Therefore may first exclude in test process these because of
Element.With an embodiment, processing mode in this case is described in detail below.
The refresh rate test side of the game of mobile terminal screen-picture change that Fig. 2 provides for the embodiment of the present invention
The flow chart of method embodiment two, as in figure 2 it is shown, the method for the present embodiment includes:
Step S201, the game screen color data change of monitoring mobile terminal.
Step S202, there is the timestamp information of change every time in record color data.
Step S203, calculates this color data and occurs the timestamp information of change and a front number of colors every time
According to the time difference between the timestamp information of appearance change, obtain the game screen picture change of mobile terminal
The first time-delayed sequence.
Specifically, after have recorded record color data and occur every time the timestamp information of change, can be by
The timestamp sequence of the game screen picture change of mobile mobile terminal is obtained according to preceding method, the most permissible
First it is processed, obtain the first time-delayed sequence of mobile terminal.
Specifically, if the timestamp sequence of the game screen picture change of game of mobile terminal is T, T={t0,
T1, t2 ..., t (n-1), t (n) }, then the first time-delayed sequence of the game screen picture of mobile terminal is D,
D={t1-t0, t2-t1 ..., t (n)-t (n-1) }.Each element in i.e. first time-delayed sequence is mobile terminal
Game screen picture color data timestamp information and a front game screen picture of change occur every time
There is the time difference between the timestamp information of change in color data.So first time-delayed sequence namely moves
The change frequency sequence of the game screen picture of dynamic terminal.
Step S204, removes the value more than Preset Time difference limen value in the first time-delayed sequence, obtains mobile whole
Second time-delayed sequence of the game screen picture change of end.
Specifically, in the first time-delayed sequence, each parameter represents the screen-picture number of colors of mobile terminal
According to the time interval between every twice change, if this time interval is long, tester has been able to from screen
Observe on Mu that card occurs in game process, then this time changes irregular change situation, the most permissible
This change is removed from the first time-delayed sequence.Or this time interval is long is also likely to be tester
Artificially suspend test, then also need from the first time-delayed sequence, remove this change.In a word, at this
Needing to remove the value being more than Preset Time difference limen value in the first time-delayed sequence, this Preset Time difference limen value is general
Can substantially observe the time of time delay for human eye, such as, could be arranged to 500 milliseconds, or other are fitted
The value closed.After removing corresponding value, obtain a new sequence, be referred to as the second time-delayed sequence.
Step S205, calculates second time-delayed sequence number of elements in Preset Time window, obtains mobile whole
The refresh rate of the game screen picture change of end.
Specifically, each element in the second time-delayed sequence i.e. means the refresh events of a screen, that
As long as calculating second time-delayed sequence number of elements in Preset Time window, i.e. can get mobile terminal
The refresh rate of game screen picture change.Certainly, usually, the test to game process be one continue
Process, then equally every default test period, calculate second time-delayed sequence when default
Between number of elements in window, thus obtain in testing time section, the game screen picture of mobile terminal becomes
The refresh rate sequence changed.
In implementing shown in Fig. 2, relate to the process that each sequence is calculated and processed, in order to become apparent from
Be described, below with a series of schematic diagrams to its describe in detail.Fig. 3 A and Fig. 3 B is Fig. 2
The schematic diagram of each sequence in illustrated embodiment.Wherein Fig. 3 A is the game screen picture of mobile mobile terminal
The timestamp sequence diagram of change, i.e. corresponding sequence T, T={t0, t1, t2 ..., t (n-1), t (n) },
Each change representing a screen-picture color data in figure.Fig. 3 B is the first time-delayed sequence schematic diagram,
I.e. corresponding sequence D, D={d1, d2 ..., dn}={t1-t0, t2-t1 ..., t (n)-t (n-1) }, namely
Calculate the time difference between each two time point in sequence T, each element representation one in sequence D
The individual time period.In the first time-delayed sequence, remove the value more than Preset Time difference limen value, i.e. obtain second
Time-delayed sequence, for the ease of follow-up explanation, be assumed herein that in the first time-delayed sequence be not greater than preset time
Between the value of difference limen value, i.e. there is no a removed point, namely the first time-delayed sequence and the second time-delayed sequence identical,
Fig. 3 B is similarly the schematic diagram of the second time-delayed sequence.During the second time-delayed sequence is calculated,
Being to calculate second time-delayed sequence number of elements in Preset Time window, in figure 3b, window 31 represents
This Preset Time window, then namely calculate the second time-delayed sequence has how many elements in window 31.And
Every second time-delayed sequence of default calculating number of elements in Preset Time window, be equivalent to preset
Test period sliding window 31, at a distance of a default test period between each window 31, preset
Test period be equivalent to the step-length of window 31 forward slip.In each window 31, all calculate second prolong
The number of elements of time series, thus obtain the refresh rate sequence of the game screen picture change of mobile terminal.
In fig. 3b it is assumed that the left side of window 31 is at d (i) place, the right side of window 31 is at d (j) place, then
Rps (i)=j-i.
Default test period can be a time span determined, such as 16 milliseconds, 32 milliseconds etc..
But in the case of more, can be defined as the number of element, example in the second time-delayed sequence default test period
Such as 1 element or 2 elements.In conjunction with Fig. 3 B, it is assumed that default test period is 2 elements, then the
It is positioned at d1 on the left of one window 31, will slide at d3 on the left of second window 31.Preset test
The size in cycle has influence on the degree of accuracy to refresh rate test and amount of calculation size.By the second time-delayed sequence
The length of the rps sequence that D2 calculates with the corresponding relation of the length of D2 sequence is:
L (rps)=L (D2)/step.Wherein L (rps) represents the length of rps sequence, and L (D2) represents the second time-delayed sequence
Length, step represents that the length of default test period (is in the second time-delayed sequence with default test period
As a example by the number of element).
In step S101, mobile terminal screen is monitored using multiple method, the most permissible
Directly read every time from the refresh events of Back Buffer to Front Buffer from caching, or from CPU
The event that middle acquisition refreshes every time.But said process needs to invade the game process itself being currently running, can
The game process being currently running can be produced certain impact, thus final test result is produced impact.
Therefore, the embodiment of the present invention also provides for a kind of method being monitored mobile terminal screen, and the method is not
Invade tested game process, it is possible to obtain the refreshing of more accurate game of mobile terminal screen-picture change
Rate.
The refresh rate test side of the game of mobile terminal screen-picture change that Fig. 4 provides for the embodiment of the present invention
The flow chart of method embodiment three, as shown in Figure 4, the method for the present embodiment includes:
Step S401, creates the virtual screen corresponding with the game screen picture of mobile terminal, will be mobile whole
The game screen picture of end is mapped in virtual screen.
Specifically, in order to avoid the game process on the mobile terminal being currently running is produced impact, permissible
First create the virtual screen corresponding to game screen picture with mobile terminal, and by the game of mobile terminal
Screen-picture is mapped in virtual screen.This virtual screen independent of the game screen picture of mobile terminal,
When the game screen picture of mobile terminal changes, game screen picture all can be mapped to this virtual screen
On curtain.
Owing in the terminal, may full screen display game be likely to only use the display trip of a part of screen
Play, the virtual screen created the most in this step is only corresponding with the game screen picture of mobile terminal, and
