Fig. 2 is refer to, for the schematic flow sheet of the method for another image taking provided in an embodiment of the present invention, this method
Comprise the following steps：
S201, when receiving shooting instruction, the first shooting unit is controlled to perform focus operation along preset direction, and
First image unit is obtained from starting to perform focus operation to terminating acquired at least two during focus operation
Focusing parameter value.
In the specific implementation, the present embodiment can be applied to the equipment with shoot function for possessing two or more cameras
In, the equipment with shoot function can include the camera with two or more cameras, mobile phone, tablet personal computer, pen
Remember this computer etc., subject can be portrait, or such as landscape, article.The terminal comprises at least first count
Unit and second shooting unit are taken the photograph, wherein, first shooting unit correspondent entity device is first group of camera, and described first group is taken the photograph
As head can be the camera that one or more is fixed in the range of first area；Second shooting unit correspondent entity device is the
Two groups of cameras, second group of camera can be the camera that one or more is fixed in the range of second area.It is described
First area in terminal can be that the midpoint at the distance between optical center and imaging plane center is boundary, first area with

Domain, or the region away from camera lens is first area, the region close to camera lens is second area.Reference object is locked when taking pictures
After in fixed and camera lens, two or more cameras of terminal can be opened while focused, complete image taking task.
Before being shot, the preset direction of terminal can pass through the tool according to first shooting unit and second shooting unit
Body position determines, wherein preset direction can be the then preset direction from reference object to the horizontal direction of the terminal
Opposite direction for from the terminal to the horizontal direction of the reference object or preset direction for from the terminal to institute
The horizontal direction of reference object is stated, then the opposite direction of the preset direction is from reference object to the horizontal direction of the terminal.
From starting to perform focus operation to during terminating focus operation, first image unit is obtained according to focus algorithm by terminal
At least two Focusing parameter values, and feed back the distance of the clear position currently focused and camera lens.
S202, control opposite direction of the second shooting unit along preset direction to perform focus operation, and obtain described the
Two image units are from starting to perform focus operation to terminating acquired at least two groups of Focusing parameter values during focus operation.
In the specific implementation, the focus operation of the first shooting unit and second shooting unit is carried out simultaneously, that is, exist
When receiving shooting instruction, terminal controls first shooting unit simultaneously and second shooting unit performs focus operation, but first count
The focus operation direction for taking the photograph unit and second shooting unit is opposite direction each other.By taking the mobile device of dual camera as an example, two
Camera optimal focusing position of moving lens removal search since specified location, a camera are close to the position of reference object
Put, its focusing motor is along reference object to imaging plane or photo-sensitive cell direction moving lens, the focusing of another camera
The focusing motor moving direction of motor and previous camera on the contrary, each camera calculates Focusing parameter value according to focus algorithm,
And the distance of the clear position of Real-time Feedback focusing and camera lens.
S203, according to the first Focusing parameter value and the variation tendency of the second Focusing parameter value, judge whether pair
Jiao's success.
