The rotary speed to match, the basis for estimation that on the other hand whether can terminate as rotation, pre-set velocity orientation matching list, and root
According to the rotary speed that the orientation values of the selection of Velocity Azimuth matching list and subject match, according to the side with subject
The rotary speed that place value matches rotates terminal, to realize accurate rotation to terminal camera, according to being taken pair
The orientation values of elephant judge whether terminal is completed to rotate, and work as and judge that the terminal completes rotation according to the orientation values of subject
During action, shooting operation, the orientation values phase by obtaining the orientation values of subject automatically and with subject are performed
The rotary speed matched improves the efficiency of shooting.
One of ordinary skill in the art will appreciate that realizing all or part of flow in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in a computer read/write memory medium
In, the program is when being executed, it may include such as the flow of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
Dish, CD, read-only memory (Read-Only Memory, ROM) or random access memory (Random Access
Memory, RAM) etc..
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent variations made according to the claims of the present invention, is still within the scope of the present invention.
