Step S200, it is judged that whether there is pupil in described image；The most then perform step S300；If it is not, then terminate.
Wherein, the scheme of Pupil diameter can identify targeting scheme based on facial characteristics；Or use by launching infrared ray, and lead to
Cross the reflective targeting scheme that identifies of the infrared ray in pupil, or other schemes.
Step S300, then generate the Virtual Space line between described pupil and described photographic head.As it is shown in figure 5, it is mobile
By calculating, digitized presents the position of pupil to terminal；Then the data of described Virtual Space line can be obtained.
Step S400, obtains the geometrical relationship of described Virtual Space line and display screen, and according to described geometrical relationship with
The optimum geometrical relationship preset obtains and adjusts parameter.Wherein, the position of display screen, mobile terminal can be defaulted in when dispatching from the factory；
User can also be pointed out to carry out associative operation when the later stage, such as, display screen horizontal positioned and display screen vertically placed, from
And initialize the photographic head of mobile terminal and the position coordinates of display screen.Optimum geometrical relationship could be arranged to: Virtual Space is even
Line and display screen are 90 ° of angular relationships, or in 70 ° of angular relationships or other.In the present embodiment, as shown in Figure 7 and Figure 8,
Illustrated therein is the front-facing camera eyeglass 3 of pupil 5, mobile terminal display screen 2, mobile terminal, and mobile terminal is preposition
Camera sensing device 4.It is 90 ° of angular relationships that the optimum geometrical relationship of the present embodiment is set to Virtual Space line with display screen；
As it is shown in fig. 7, current acquisition states angle K1 between Virtual Space line 1 and display screen 2 when being 70 °, then adjust parameter be+
20°；As shown in Figure 8, current acquisition states angle K3 between Virtual Space line and display screen when being 120 °, then adjust parameter
For-20 °.The present embodiment thinks in absolute terms with camera position relation with display screen, comes as a example by i.e. photographic head and display screen move jointly
Illustrate, in other schemes, it is also possible to be that photographic head is for fixing and display screen rotation, then when display screen is according to described adjustment parameter
And when rotating, system should update the coordinate position of display screen according to described adjustment parameter, thus ensure to be obtained by photographic head
Image and correctness when adjusting display screen angle again.
Step S500, sends described adjustment parameter to adjusting parts, in order to according to aobvious described in described adjustment parameter adjustment
The displaying direction of display screen.The mobile terminal that the present embodiment is applied is not provided with adjusting parts, and therefore this adjustment parameter will send
Support unit to the outside being connected with this mobile terminal data；And after described support unit receives this adjustment parameter, will drive
Dynamic servomotor rotates thus carries out pose adjustment, so drive mobile terminal thereon show direction change into default
Good direction.It should be noted that at the end of adjusting, step S100 can be repeated immediately and confirm, or during one section of interval
