State whether reference object is kept in motion, including：
Shot using any camera collection reference object in infrared sensor or at least two camera
Position in picture, the change in location based on the reference object for collecting determines the movement velocity of reference object, based on the bat
The movement velocity for taking the photograph object judges whether the reference object is kept in motion.
The embodiment of the present invention determines this based on the image of the reference object taken by infrared sensor or camera
The motion state of reference object, can accurately capture the motion state of reference object.
Step S102, when the reference object is kept in motion, is shot using at least two camera；
Each camera is mutually misaligned in time for the periodicity shooting operation of picture frame；
Step S103, the picture frame that at least two camera shoots sequentially in time preserve obtaining video
File.
Optionally, the reference object is to defocused reference object.Due to being transported for defocused reference object
The judgement of dynamic state and when carrying out the shooting of video, can become apparent from the reference object in shooting picture, improve image quality.
Optionally, each camera is equal for the shooting cycle of picture frame.Below with comprising being taken the photograph positioned at the double of the same face
As a example by as the mobile terminal of head, shooting control modes of the step S102 to dual camera is introduced：Dual camera is the first camera
And second camera, be that the first camera and second camera setting shooting time are poor, such as the shooting of current each camera
Frame per second is 60 frames/second, then the first camera shoots a picture frame, and second camera since the 1st millisecond every 1 millisecond
The same frame per second for being kept for 60 frames/second, its since 1.5 milliseconds ing every 1 millisecond of shooting, one picture frame, then by the two cameras
The picture frame of shooting preserves to form video file sequentially in time, and then compared with prior art, the video frame rate that will be shot
Improve one times.
Because when swiftly passing object is clapped, now the picture of two camera shootings need not carry out picture synthesis, therefore
Synchronization is not required to, so for the mobile terminal comprising multiple cameras, in above-mentioned setting shooting time difference, it is also possible to which adjustment is more
The video frame rate of one or two camera in individual camera, and then further lift the video shot to high-speed moving object
Frame per second.
