The mobile terminal is waited in the focusing confirmation signal for receiving target user's transmission, then by delays time to control unit of taking pictures
Then, by taking pictures, execution unit sends pair determined before focusing confirmation signal to preset time with target user to the camera
Burnt position is focused, and is passed through the camera and taken pictures.After focusing confirms and before being taken pictures, reserve
Preset time facilitates user more to meet that target user takes pictures according to the direction of gaze of the hobby adjustment eyes of taking pictures of oneself
Property demand, the user experience for making mobile terminal are more preferable.
In conclusion mobile terminal of the present invention and its photographic method, compared with prior art, have the following advantages：It is mobile
Terminal first identifies the eyeball of target user in display screen when taking pictures, and determines the eyeball position of target user in display screen；Then
The eyeball position of the target user according to display screen determines the focusing position of the camera；Determined by last foundation
Focusing position is focused, and is passed through the camera and taken pictures.The photographic method of this mobile terminal being capable of automatic identification mesh
The eyeball of user is marked, tracking eyeball carries out auto-focusing, then takes pictures.The step of eliminating user's manual focus, in letter
Change take pictures step while, the quality of captured photo can be improved, effectively increase the user experience of mobile terminal.
