Range.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
Fig. 1 is the schematic flow of the main screen selection method of multi-screen mobile terminal according to an embodiment of the invention
Figure, is affected user experience by way of manual setting main screen determination in the prior art by solving the problems, such as.It is mobile whole
End is taken the photograph including the first screen, the second screen, the first photographic device positioned at the first screen side and second positioned at the second screen side
As device.The main screen selection method of the embodiment of the present invention can include:
S102. the first input of user is received.
Under normal circumstances, mobile terminal is in shutdown or standby mode, before determining the main screen of mobile terminal, if mobile
Terminal is in off-mode, then user is needed to start mobile terminal, and when mobile terminal is in standby, then need user to unlock
Mobile terminal.First here, which inputs, as a result, to be starting or the operation of unlock mobile terminal, and receives user to mobile whole
Hold the operation signal of the starting or unlock made.
S104. in response to the first input, the first image is acquired by the first photographic device, and adopt by the second photographic device
Collect the second image.
After mobile terminal starts or unlocks, the first photographic device of the first screen and the second photographic device of the second screen
Can the operation of the starting of (or sequentially, can be specifically configured according to actual condition) response mobile terminal or unlock simultaneously, acquisition the
One, two image, to prepare to determine that main screen carries out Image Acquisition information.
S106. the human face image information in the first image and the second image based on acquisition determines that main screen, main screen are
One in first screen and the second screen.
When the first photographic device of the first screen side is collected the second photographic device acquisition of the first image, the second screen side
After second image, then the master in the first screen and the second screen can be determined according to the human face image information in the first and second image
Screen.In this way, the main screen selection method in the embodiment of the present invention is not necessarily to through manual hand manipulation, but pass through two differences
Different photographic devices (the first and second photographic device) acquired image (the first and second image) of (such as the first and second screen) at screen
In human face image information can judge the main screen in different screen, realize main screen to avoid by manual hand manipulation
Really it is fixed the usage experience for ringing user.
It can be seen that multi-screen mobile terminal increases one or more screens, can not only it make user according to difference
Needs operated on different screens, to meet the different demand for experience of user, but also can solve and lead in the prior art
Cross the problem of mode that manual setting main screen determines affects user experience.
In the above-described embodiments, based on the human face image information in the first image and the second image, the behaviour of main screen is determined
Make, specifically can include:
If the ratio of the first screen shared by the human face image information in the first image is greater than the facial image in the second image
The ratio of second screen shared by information, it is determined that the first screen is main screen.
If the ratio of the first screen is less than the facial image in the second image shared by the human face image information in the first image
The ratio of second screen shared by information, it is determined that the second screen is main screen.
It should be understood that under normal circumstances, if mobile terminal such as mobile phone there are two screen, defines based on the screen towards user
Screen, the screen backwards to user are vice screen.After mobile terminal such as mobile phone power-on or unlock bright screen, with mobile phone tool, there are two screens
For curtain, system can open simultaneously the first and second photographic device being respectively arranged at two screens on backstage to human face image information
It is acquired and can be with preview.
At this point, the ratio of screen, ordinary circumstance can be corresponded to shared by human face image information in the first and second image of backstage comparison
Under, the ratio of screen shared by face is bigger, illustrates that the corresponding user of the screen is user, it may be determined that based on corresponding screen
Screen is determined in the first and second screen with showing the main screen so as to correspond to the ratio of screen according to shared by human face image information
Main screen, determine main screen to avoid by manual hand manipulation.
In a specific embodiment, when mobile terminal-opening, the corresponding photographic device acquisition of the first screen is
The image information of user's face, the second photographic device detect other people face (i.e. the image information of his face), but due to user
Close to the first photographic device, therefore the ratio regular meeting of the first screen shared by face is than the second camera shooting in the image of the first photographic device acquisition
The ratio of the second screen shared by face is bigger in the image that device obtains, so as to confirm that the first screen is main screen.Thus may be used
See, passes through different photographic devices (the first and second photographic device) figure collected of (such as the first and second screen) at two different screens
Human face image information in picture (the first and second image) can judge the main screen in different screen, to avoid artificial hand is passed through
Dynamic operation realizes that main screen is fixed the usage experience for ringing user really, to solve in the prior art through manual setting main screen
The problem of mode that curtain determines affects user experience.
Wherein, since the first and second photographic device can be used merely to identification human face image information, first and second can be taken the photograph
As device is each configured to export with the gray level image of low pixel, in order to reduce the power consumption of mobile terminal, and promoted at data
The speed of reason.It is of course also possible to configure the first and second photographic device to by a processor or controller the grayscale image of low pixel
As output.
In the above-described embodiments, the operation for determining the first screen and the main screen in the second screen, may also include that
Obtain the first distance of the first face and the first screen and the second distance of the second face and the second screen.For example,
What the corresponding photographic device of the first screen acquired is the image information of user's face (the first face), and the second photographic device detects it
Other people face (i.e. the second face), but the user since mobile terminal is generally used can be close to the screen of mobile terminal, i.e.,
First distance is less than second distance, accordingly, it can be determined that the first screen is main screen.
Therefore, according to the second distance of the first distance and the second face and the second screen of the first face and the first screen,
Determine that the operation of main screen can be with are as follows: if first distance is less than second distance, it is determined that the first screen is main screen.Or, if
One distance is greater than second distance, it is determined that the second screen is main screen.If first distance is equal to second distance, can enable pre-
The screen first set is determined as main screen.
Specifically, the first face and the first screen can be detected respectively by being located at the position sensor at mobile terminal
The second distance of first distance and the second face and the second screen, then by processor or controller to first distance with
Second distance is compared, and determines the main screen in the first screen and the second screen according to the result of the comparison.In addition, passing through position
The first and second face can be believed with the distance detection method of mobile terminal screen in the facial image of the first image respectively by setting sensor
Cease the second screen shared by the shared ratio of first screen and the human face image information of the second image the case where being in equal proportions after, then
It is detected；It certainly, can also be in the ratio of the first screen shared by the human face image information of the first image and the face of the second image
Second screen shared by image information carries out before the case where being in equal proportions, can be first according to face proportion, then by face
It is carried out with the detection ordering at a distance from screen, can not also carry out according to the sequence, can specifically be carried out according to actual condition demand.
It should be understood that human face image information in the first and second photographic device the first and second image collected respectively shared the
One, the ratio of two screens may be equal, at this point, detectable face respectively with the distance between the first screen, the second screen, one
As for, user or user can be close to mobile phones when using mobile phone, and another photographic device may detect other faces
In contrast farther out apart from mobile phone screen therefore image information, can be determined by comparing the distance between face and two screens
Main screen in first and second realizes that main screen is fixed the use of sound user really so as to avoid passing through manual hand manipulation
Experience, is affected user experience by way of manual setting main screen determination in the prior art by solving the problems, such as.
During by use, posture may change mobile terminal, at this point, if only with mobile terminal
Posture changes the screens switch currently shown to another screen, may influence whether the usage experience of user.For example,
User is initially in sitting using the first screen of mobile phone, and after using for a period of time, user may lie down using mobile phone, this
When, the posture of mobile phone changes, but what user was used or watched is still the first screen, if due to the posture of mobile phone
It changes and automatically switches to the second screen, this undoubtedly brings worried or bad usage experience to user.
To solve the above problems, in the embodiment of fig. 2, the first input can be overturning mobile terminal for the first input
Operation.So, the first image is acquired by the first photographic device in step S104, and the second figure is acquired by the second photographic device
Picture, it may include:
S202. in response to the first input, the sensing data of mobile terminal is monitored.It can real-time or stage monitoring movement
The sensing data of terminal, the sensing data can be the gravimetric data or top of gravity sensor mobile terminal detected
The change in location data of spiral shell instrument mobile terminal detected.
S204. it is based on sensing data, determines whether the posture of mobile terminal changes.(i.e. according to sensing data
Gravity sensor gravimetric data detected or gyroscope change in location data detected) posture that can determine mobile terminal is
No variation, specifically can include:
If the difference in change between sensing data and mobile terminal locations sensing data corresponding when not changing
Value is less than or equal to preset threshold, then can determine that the posture of mobile terminal does not change.For example, the main screen of current operation can
Continue as the first screen.
If the difference in change between sensing data and mobile terminal locations sensing data corresponding when not changing
Value is greater than preset threshold, then can determine that the posture of mobile terminal changes.
Wherein, since the power consumption of gravity sensor or gyroscope is relatively low, gravity sensor or gyro can be made
Instrument is constantly in working condition, certainly, in order to reach further energy-efficient effect, gravity sensor or gyroscope can be made one
It does not work in the fixed time, for example mobile terminal is in standby or other closable states, it specifically can be according to the reality of user
Demand is configured.
S206. in the case where the posture of mobile terminal changes, then the first image is acquired by the first photographic device,
And the second image is acquired by the second photographic device.
After the posture for determining mobile terminal changes, it cannot also determine whether the main screen of mobile terminal becomes
Change, at this point, can by opening simultaneously the first photographic device of the first screen and the second photographic device of the second screen, acquisition and/
Or the first and second image of preview, to carry out the preparation of Image Acquisition information to redefine main screen.
Then it further according to the human face image information in the first and second image of acquisition, determines in the first screen and the second screen
Main screen.
When the first photographic device of the first screen side is collected the second photographic device acquisition of the first image, the second screen side
After second image, then it can be redefined in the first screen and the second screen according to the human face image information in the first and second image
Main screen.In this way, the main screen selection method in the embodiment of the present invention is not after the posture of mobile terminal changes
Directly switch main screen, also redefines main screen not by manual hand manipulation, but pass through at two different screens (such as
First and second screen) the image (the first and second image) that resurveys of different photographic devices (the first and second photographic device) in people
Face image information can judge the main screen in different screen, cause main screen to go out to avoid by directly switching main screen
Mistake realizes that the determination of main screen influences the usage experience of user by manual hand manipulation, to solve in the prior art
The problem of being affected user experience in such a way that manual setting main screen determines.
In any of the above-described embodiment, the main screen selection method of multi-screen mobile terminal may also include that
Start the first photographic device of the first screen side and the second photographic device of the second screen side when acquiring image.
That is, needing first to start the first photographic device and the second screen of the first screen when mobile terminal is activated or is unlocked bright screen
The second photographic device the acquisition of image just can be achieved thus after the first photographic device and the second photographic device are activated, with
Prepare to determine that main screen carries out Image Acquisition information.
In any of the above-described embodiment, as shown in figure 3, the main screen selection method of multi-screen mobile terminal can also wrap
It includes:
S108. the first photographic device of the first screen and the second camera shooting dress of the second screen are closed after determining main screen
It sets.The power consumption of general photographic device is bigger, in order to save electric energy, after determining main screen every time, can close the
One photographic device and the second photographic device.Certainly, it in order to meet whether user needs the needs of closing photographic device, can set
One preset time closes photographic device when reaching the preset time after determining main screen every time.Certainly, it can not also close
Photographic device can be specifically configured according to the actual use demand of user.
In a specific embodiment, it is illustrated in combination with Fig. 4, here for having the mobile phone there are two screen.
The two pieces of screens that can define Dual-band Handy Phone are respectively the first screen and the second screen, and the first screen may be configured with the first camera,
Second screen may be configured with second camera, and can define towards the screen of user is main screen, and the screen backwards to user is vice screen.Hand
Gravity sensor or gyroscope monitoring mobile phone posture can be carried on machine, be reported to processor.The preview of camera backstage can cooperate knowledge
The usage scenario of other user, to confirm main screen.
Originally mobile phone is typically in shutdown or standby mode, and when mobile phone power-on or the bright screen of unlock, system generally can be same
When open two cameras (such as the first photographic device and the second photographic device) and carry out backstage previews, to compare in two images
The face accounting (ratio of the first screen or the second screen shared by human face image information) of (such as the first and second image).If first
The ratio of first screen shared by face in photographic device acquired image is greater than in the second photographic device acquired image
Face shared by the second screen ratio, at this point, the first photographic device (the biggish camera of face accounting) can notifier processes device,
And determine that corresponding first screen is the main screen that is switched on, while the first, second photographic device can be closed, to reduce power consumption.Thus
As it can be seen that the multi-screen selection method of this specification embodiment can avoid passing through manual hand manipulation realize main screen determination from
And influence the usage experience of user.
If the first photographic device collects the face image information of user when booting, the second photographic device detects other people
Face image information, but since user is close to the first photographic device, therefore face accounting is more in the image that obtains of the first photographic device
Greatly, so that the first screen of confirmation is main screen.But the people being also possible in the first and second photographic device the first and second image collected
The ratio regular meeting of face image information shared first and second screen respectively is equal, at this point, detectable first face and the first screen and
The distance between second face and the second screen, in general, user or user (can be passed through when using mobile phone close to mobile phone
First photographic device detects the first face), and another photographic device may detect that other face (the second face) images are believed
Breath, in contrast farther out apart from mobile phone screen, therefore, can by comparing the distance between face and two screens determination first,
Main screen in two realizes that main screen is fixed the usage experience of sound user really so as to avoid passing through manual hand manipulation,
To solve the problems, such as to affect user experience by way of manual setting main screen determination in the prior art.
Wherein, camera or photographic device are used merely to identification face (or other image informations), processor can by first,
Second photographic device is configured to the gray level image output of low pixel, in order to reduce power consumption and promote data processing speed.
During mobile phone is by use, cell phone system can obtain the sensing data of gravity sensor or gyroscope, from
And the current posture of mobile phone can be calculated, the state for the initial time that recordable mobile phone is used is initial attitude.If mobile phone
Posture do not change, i.e. gravity or gyro data variation does not exceed preset threshold X, then current operation main screen can be after
Continue for the first screen.
If mobile phone posture changes, for example mobile phone is flipped, and gravimetric data variation can be more than preset threshold X, then
System is believed that mobile phone has sent out overturning, at this point, processor can open simultaneously two camera backstage previews, by comparing two figures
As the face accounting in (i.e. the first and second image), confirmation is only that the attitudes vibration of mobile phone or the posture of user are also sent out therewith
Changing.For example, user has only overturn mobile phone, at this point, main screen can be switched to the second screen；And if user only such as from
The operating handset of bowing of being seated becomes recumbency and faces upward an operating handset, at this point, user and mobile phone posture are all changed, then, class
Like this operation then still using the first screen as main screen.Wherein, gravity sensor and gyroscope power consumption are low, can work always
Make, continues to monitor mobile phone posture.
Since the main screen selection method in the embodiment of the present invention not is straight after the posture of mobile terminal changes
Switching main screen is connect, also redefines main screen not by manual hand manipulation, but passes through at two different screens (such as the
One, two screen) the image that resurveys of different photographic devices (the first and second photographic device) in human face image information can sentence
Main screen in disconnected different screen out causes main screen to malfunction or by manually to avoid by directly switching main screen
The usage experience for operating the determination for realizing main screen and influencing user, to solve in the prior art through manual setting main screen
The problem of mode that curtain determines affects user experience.
It should be noted that some executing subjects of each step of above-described embodiment institute providing method can be same set
It is standby, alternatively, this method can also be by distinct device as executing subject.For example, the executing subject of step S102, S104 can be same
One executing subject, and the executing subject of step S106 then can be another executing subject (such as control unit)；For another example, step
The executing subject of S102, S104, S106 all can be the same executing subjects etc..
The embodiment of the present invention also provides a kind of main screen selection device of multi-screen mobile terminal, in combination with Fig. 5 and Fig. 6 into

In determining main screen according to the human face image information in the first and second image collected, main screen is the first screen 501 and second
One in screen 502.Wherein, mobile terminal includes the first screen 501 and the second screen 502.
When response receiving unit 500 received first inputs, the first photographic device 503 is collected the first image, second takes the photograph
After being collected the second image as device 504, then the first screen 501 can be determined according to the human face image information in the first and second image
With the main screen in the second screen 502.In this way, the main screen selection device in the embodiment of the present invention is not necessarily to by manually grasping
Make, but is acquired by the different photographic devices (the first and second photographic device) at two different screens (such as the first and second screen)
Image (the first and second image) in human face image information can judge the main screen in different screen, to avoid people is passed through
The determination for realizing main screen is manually operated and the usage experience for influencing user in work, sets manually to solve and pass through in the prior art
Set the problem of mode that main screen determines affects user experience.
In the above-described embodiments, main screen determination unit 506 is configured to: if shared by human face image information in the first image
The ratio of first screen 501 is greater than the ratio of the second screen 502 shared by the human face image information in the second image, it is determined that first
Screen 501 is main screen；If the ratio of the first screen 501 is less than in the second image shared by the human face image information in the first image
Human face image information shared by the second screen 502 ratio, it is determined that the second screen 502 be main screen.
(the first input here can be to start or unlock institute after mobile terminal such as mobile phone power-on or unlock bright screen
State the operation of mobile terminal), by mobile phone tool there are two for screen, system can open simultaneously the be respectively arranged at two screens
