Deng.
Wherein, shooting environmental parameter, can include any one or more in zoom magnification, object distance, light conditions etc..
The current weight sum of each camera is 1.
Accordingly, step 101 can be accomplished by the following way：
According to current zoom magnification, object distance and/or light conditions, the current weight of each camera is determined.
Wherein, light conditions, power, angle, color of light etc. are referred to.
During specific implementation, the suitable zoom magnification of each camera, object distance can be determined previously according to the type of each camera
And/or the shooting environmental parameter such as light conditions, and then the shooting environmental parameter being adapted to according to each camera, current shooting is set
The mapping relations of ambient parameter and the weight of each camera.So that in shooting process, it is determined that after current shooting environmental parameter,
Can be according to default mapping relations, it is determined that the weight that each camera corresponding with current shooting environmental parameter is current.
As an example it is assumed that terminal includes camera A and camera B, it is determined that the suitable shooting environmental ginsengs of camera A
Number is：1-6 times of zoom magnification, shooting environmental parameter suitable camera B are：More than 6 times of zoom magnification.Then can basis
When above-mentioned shooting environmental parameter, current zoom magnification being set between 1-6 times, and differing more with 6 times of zoom magnification, than

Weight is 0, and sets current zoom magnification between 6-8 times, and when changing from high to low, camera A weight gradually increases,
Camera B weight is gradually reduced, until camera A weight is 1, camera B weight is 0.
Join it should be noted that camera A and camera B weight gradually increased or decrease shooting environmental corresponding to process
Several scopes, it can be arranged as required to.For example zoom magnification is could be arranged between 4.5-6 times, it can also be provided that becoming
Burnt multiple may be arranged as zoom magnification between 4.5-8 times between 6-8 times.I.e., it is possible to be only adapted in camera A
In shooting environmental parameter area, it can also can also imaged simultaneously only in the shooting environmental parameter area that camera B is adapted to
In shooting environmental parameter area suitable head A and camera B.
In addition, with the process that the change of current shooting environmental parameter, the current weight of each camera increased or decrease,
Can be it is linearly changing or it is stepped change or other rules change, be not restricted herein.
And each camera current weight increaseds or decreases process, slope during linear change, or stepped change
Step-length during change, it can be arranged as required to.For example zoom magnification can be set often to increase by 0.5 times, weighed corresponding to camera A
Reduce 0.1 again, weight increase by 0.1 corresponding to camera B；Or zoom magnification often increases by 0.5 times, weight corresponding to camera A
Reduce 0.2, weight increase by 0.2, etc. corresponding to camera B.
