Step S106, described shooting picture is searched based on face recognition technology and/or eyeball technology of identification, face will be comprised
The corresponding photographic head of shooting picture of feature and/or eyeball feature is target photographic head.
Wherein, face recognition technology is the face feature based on people, and the facial image or video flowing of input is known
Other technology.First determine whether that it whether there is face, if there is face, then further provide position, the size of each face
Positional information with each major facial organ.And according to these information, extract the identity being contained in each face further
Feature, and it is contrasted with known face, thus identifying the identity of each face.
Wherein, eyeball technology of identification is to carry out a kind of biological of identification based on the eyeprint of eyes of user iris both sides to know
Other technology, is the new biological identification technology that developed after recognition of face and fingerprint recognition.
Using face recognition technology and/or the eyeball technology of identification of existing comparative maturity, in above-mentioned steps S104
The face shooting in picture of collection and/or eyeball are identified and/or calculate the position of face, size, each major facial
The positional information of organ and eyeball feature or stare coordinate information etc..When the face characteristic identifying in shooting picture and/or eye
During ball feature, search the photographic head shooting corresponding to picture that this comprises face characteristic and/or eyeball feature, be defined as mesh
Mark photographic head.
It should be noted that target photographic head can have multiple.Specifically：When described turning operation is detected, collection
The shooting picture of each photographic head in described multi-screen terminal；Based on face recognition technology and/or eyeball technology of identification described
Shoot and in picture, search the target shooting picture comprising face characteristic and/or eyeball feature, determine that described target shoots picture pair
The photographic head answered is target photographic head.If there being multiple targets to shoot picture, determine that target shoots the corresponding target of picture respectively
Photographic head.As shown in figure 4, when overturn multi-screen terminal after, Xiao Ming and little red respectively in the face of multi-screen terminal front and back, first
Photographic head gathers the shooting picture of Xiao Ming, and second camera gathers little red shooting picture, and by face recognition technology and/or
Eyeball technology of identification identifies the face characteristic and/or eyeball feature comprising Xiao Ming in the shooting picture of the first photographic head collection,
And shooting of second camera collection comprises little red face characteristic and/or eyeball feature in picture, the therefore first photographic head and
Second camera all can be judged as target photographic head.
Further, comprise face in by face recognition technology and/or eyeball technology of identification lookup shooting picture special
Levy and/or eyeball feature after, determine target shoot the corresponding photographic head of picture be target photographic head before, can first wait default
Duration, such as 1 second, that extracts the collection of each photographic head further shot the identity characteristic that contained in picture, and by its with
The reference face characteristic of pre- typing and/or reference eyeball feature carry out contrast coupling, so that it is determined that target shooting picture is corresponding
Target photographic head.Because under normal circumstances, after turning operation occurs, photographic head may collect the shooting picture of irrelevant people,
Therefore user also needs to shooting picture is screened.If comparatively fast determining target photographic head, may result in unnecessary display
Screen is opened, and display content, to everyone disclosure, causes the leakage of privacy, wasting the occupancy of electricity or system resource.And warp
Determine target photographic head again after crossing preset duration, determine rational target display screen, the privacy of protection reference man, economize on
Electricity.Specifically：Typing in advance, with reference to face characteristic and/or with reference to eyeball feature, is identified by face recognition technology and/or eyeball
Technology is searched and is mated with reference to face characteristic and/or shoot picture with reference to the shooting picture of eyeball feature as target, thus really
Set the goal photographic head.
For example, photograph the application scenarios of face in conjunction with multiple photographic head in a multi-screen terminal simultaneously.As Fig. 4 institute
Show, the reference face characteristic of multi-screen terminal typing Xiao Ming and/or with reference to eyeball feature, the wherein first photographic head corresponds to first and shows
Display screen, second camera corresponds to second display screen.Upset multi-screen terminal after, Xiao Ming and little red respectively in the face of multi-screen terminal just
Face and the back side, the first photographic head gathers the shooting picture of Xiao Ming, and second camera gathers little red shooting picture, and passes through face
Technology of identification and/or eyeball technology of identification identify the face characteristic comprising Xiao Ming in the shooting picture of the first photographic head collection
And/or eyeball feature, and shooting in picture of second camera collection comprises little red face characteristic and/or eyeball feature.By
It is Xiao Ming in the reference face characteristic of typing and/or with reference to eyeball feature, and little red reference face characteristic and/or reference eyeball
Feature not typing in advance, after the identity characteristic of face recognition technology and/or eyeball technology of identification mates, draws Xiao Ming institute
Faced by the first photographic head be target photographic head.Therefore Xiao Ming faced by the first display screen be lit, and little red faced by
Two display screens will not be lit.This allows for, and photographs under the scene of face in multiple photographic head simultaneously, irrelevant crowd institute face
To the display screen of multi-screen terminal will not random bright screen, it is to avoid light unnecessary display screen, the privacy of protection reference man,
Remaining display screen closes and goes out, and also acts the effect of power saving.
Step S108, determine the corresponding display screen of target photographic head be target screen, by system screen control and system
Power management lights described target screen.
Display screen due to multi-screen terminal is one-to-one relation with photographic head, after searching target photographic head, you can
Determine target screen.Then display screen designated order is sent to system screen control and power supply managing, thus lighting
Target screen.Without exiting application, directly upset multi-screen terminal can achieve automatic switch-over screen curtain to user.
Further, display screen designated order comprises the dispaly state of all display screens.That is target screen
State is to light, and remaining screen goes out state for pass.Therefore system screen controls and power supply managing passes through display screen and specifies
While instructing the power supply opening by target screen, close the power supply of remaining screen.The dispaly state of all display screens is carried out
The rational efficiency managing, switching display screen beneficial to raising, power supply of avoiding waste.
Wherein in an embodiment, when the display screen of user's automatic switchover multi-screen terminal, multi-screen terminal obtains upset
The corresponding display content of display screen before lighted simultaneously is shown in target screen.That is, after switching display screen, browsing interior
Hold or original browsing content, do not affect reading effect, improve reading experience and the convenience of operation.
For example, in conjunction with the application scenarios of an ocr software, as shown in figure 5, current multi-screen terminal is double-display screen,
And first display screen corresponding with the first photographic head, second display screen is corresponding with second camera.Wherein first display screen is liquid crystal
Screen, and second display screen is electronic ink screen, electronic ink screen is suitable for reading in the sun.When Xiao Wang needs electronic ink screen to read
During reading, to second display screen, now the face of Xiao Wang is in the face of second display screen for upset the first display screen.First photographic head and
Two photographic head collection shooting picture, are searched the facial picture of Xiao Wang, find by face recognition technology and/or eyeball technology of identification
The picture that shoots of second camera collection has face characteristic and/or the eyeball feature of Xiao Wang, that is, determine second camera collection
Shoot picture and shoot picture for target, second camera is target photographic head, so second display screen is target screen.So,
The browsing content of the first display screen during second display screen bright display multi-screen terminal upset, and the first display screen goes out.
Wherein in an embodiment, controlled by system screen after lighting target screen with power supply managing, etc.
Treat preset duration, such as 1 second, close each photographic head in described multi-screen terminal.After display screen handover operation occurs, take the photograph
As first straight collection shoot picture take memory space, waste electricity, may also can occupying system resources, cause multi-screen terminal to go out
Now card screen or the phenomenon crashing.And turn off photographic head collection shooting photo after preset duration, one side using electricity wisely,
On the other hand improve the utilization rate of operating system.
Wherein in an embodiment, behind the scenes when there are multiple target screens, before receiving display screen designated order, can
First wait preset duration, such as 1 second, user passed through setting and selects to need the screen lighted to determine target display screen, is converted into
Display screen designated order is then forwarded to multi-screen terminal.Because under normal circumstances, after turning operation occurs, photographic head may gather
To the shooting picture of irrelevant people, therefore user also needs to target photographic head corresponding target display screen is screened.If relatively
Fast determine target display screen, may result in unnecessary display screen and be opened, cause to waste accounting for of electricity or system resource
With.And determine target display screen after preset duration again, can reasonably be turned on or off display screen, improve display screen
Utilization rate and operation convenience.Specifically：When there is multiple described target screen, receive display screen designated order,
Described display screen designated order is lighted in the fixed screen of described target screen middle finger.
For example, in conjunction with the application scenarios of multi-screen terminal photographs at least one irrelevant people.As shown in Figure 2
Cover-turning type intelligent mobile phone there are three display planes, then selective light screen items be the first display screen, the second display
Screen and the 3rd display screen.Active user have selected the first display screen, then the first display screen will be arranged to target display screen, then will
Light the first display screen, the content transformation closing go out second display screen and the 3rd display screen becomes display screen designated order.Thus point
Bright first display screen, and close second display screen and the 3rd display screen, reasonably it is turned on or off display screen, improve aobvious
The utilization rate of display screen and the convenience of operation.
For solve conventional art in toggle screen when, need upward sliding pull out bottom of screen Option Box click on switching by
