Embodiment one
Accompanying drawing 1-3 is the flow chart of steps of the image pickup method of a kind of mobile phone of the embodiment of the present invention one, and the method comprises the following steps:
100: by the photo of front-facing camera shooting with face, obtain face location in photo.
In the present embodiment, be specially, 101: by the photo of front-facing camera shooting with face.
Such as, first open front-facing camera or open front-facing camera by triggering command, and catch image by front-facing camera, after recognizing face, user clicks shutter, then take successfully, if do not recognize face or recognize face imperfect time user just take, then prompting is taken unsuccessfully, needs again to take.
102: the eyes coordinate identifying face in photo.Such as, the eyes coordinate (x in photo is identified
1, y
1), (x
2, y
2).
103: the eyes Distance geometry face square frame position determining face in photo.Face square frame position is the position of being carried out the face square frame place that standardized calculation obtains by eyes coordinate.
As above, in example, eyes distance is (x
