In other words, detection module 110 is for detecting the distance moved needed for focus lens 210.Judgment module 120 is used for
Judge whether distance is greater than or equal to predetermined value.Adjustment module 130 is used to be greater than or equal to predetermined value in the distance of required movement
When, the revolving speed of focusing motor 220 is adjusted according to the distance of required movement.
Focus process in video shooting mode is a continuous focusing process.After completing a focus operation, focusing
Camera lens 210 is not locked.When subject is mobile or artificially control imaging device 200 is mobile, need again into
Row focusing.However in certain photographed scenes, such as the mobile range of subject is bigger or artificially with larger amplitude
When degree control imaging device 200 is mobile, imaging device 200 is mobile focus lens 210 needed for completing focus operation next time
Distance is longer.At this time according to original setting, imaging device 200 may quick rotation focusing motor 220 to drive focusing mirror
First 210 fast move to fast implement focusing.
It is appreciated that frame stabilization in video is poor when fast driving focus lens 210 are mobile, may produce
Raw biggish shake, picture can jump in other words.The phenomenon that video recorded at this time will appear Caton.
Specifically, during recorded video, imaging device 200 can calculate the target moved required for focus lens 210
Then point pushes focus lens 210 to target point by current location.Current location to the distance between target point be focusing mirror
The distance moved needed for first 210.Detection module 110, which is exactly based on, calculates current location to the detection in turn of the distance between target point
The distance moved needed for focus lens 210.
Next, it is judged that module 120 judges whether required mobile distance is greater than or equal to predetermined value.In required movement
Distance be less than predetermined value when, it is believed that imaging device 200 push focus lens 210 speed be within an acceptable range,
Captured video is still more smooth.Therefore it when the distance of required movement is less than predetermined value, does not need to adjust focusing
The revolving speed of motor 220.Only when the distance of required movement is greater than or equal to predetermined value, captured video is possible to occur
The phenomenon that Caton.It is thus just needed when the distance of required movement is greater than or equal to predetermined value through the reduction pair of adjustment module 130
The revolving speed of burnt motor 220.
In this way, focus lens 210 will be slow movement.The variation of corresponding picture can be smoother, to be effectively prevented
There is a phenomenon where jump for picture.
It should be noted that the size of predetermined value can be by examining imaging device 200 during recorded video
It measures.It is sequentially increased the distance moved needed for focus lens 210 for example, can control imaging device 200 and observes and recorded
Video whether Caton phenomenon occurs.When just Caton phenomenon occurs for the video recorded it is corresponding needed for moving distance can be with
It is confirmed as predetermined value.In addition the size of predetermined value can be accurately detected by multiple checks.The size of predetermined value can also
It is determined in a manner of being inputted by user, such as shows that predetermined value adjusts pattern in user interface, user can pass through a little
It hits, the mode of touch-control or dragging adjusts the size of predetermined value.
In this way, when control method and control device 100 of the invention is longer by the moving distance needed for focus lens 210
The revolving speed for reducing focusing motor 220 can effectively prevent picture when shooting video to jump.
In some embodiments, control method is focused for controlling imaging device 200 using phase focal modes, step
Distance S10 mobile needed for being obtained by the phase difference that phase focal modes obtain.
In some embodiments, control device 100 is focused for controlling imaging device 200 using phase focal modes,
The phase difference that detection module 110 is used to obtain by phase focal modes distance mobile needed for obtaining.
Specifically, in phase focal modes, the pixel of imaging sensor (not shown) is usually pairs of by left and right pixel
Composition.Imaging device 200 generates the data waveform of left pixel and the data waveform of right pixel respectively.When the number of left pixel
When being overlapped according to the data waveform of waveform and right pixel, captured picture is the most clear, that is, focuses successfully.When left pixel
It, can be according to phase difference calculating focus lens 210 between the two when the data waveform of data waveform and right pixel is not overlapped
The distance of required movement.
In this way, distance mobile needed for being obtained by the phase difference that phase focal modes obtain.
In some embodiments, control method is focused for controlling imaging device 200 using laser focal modes, step
S10 passes through distance mobile needed for the detection of laser focal modes.
In some embodiments, control device 100 is focused for controlling imaging device 200 using laser focal modes,
Detection module 110 is used for through distance mobile needed for the detection of laser focal modes.
Specifically, laser focusing is usually to be not easy the characteristic spread by force using infrared laser centrality, infrared by recording
Laser is emitted from device, is reflected by target surface, the time difference finally received further according to rangefinder, to calculate target
To the distance of test equipment.This distance is the object distance in focus process, coke of the imaging device 200 further according to focus lens 210
Away from the size for calculating image distance.According to the size of image distance, the distance moved needed for focus lens 210 can be gone out.
In this way, the distance moved needed for focus lens 210 can be detected by laser focal modes.
Referring to Fig. 3, in some embodiments, control method further comprises the steps of:

In determining multiple distance segments and multiple corresponding revolving speeds.The distance segment control focusing that adjustment module 130 is used to be fallen into according to distance
Motor 220 uses corresponding revolving speed.
Specifically, in due to video record process, when the distance moved needed for focus lens 210 is very big, such as
When being switched to distant view progress video capture by close shot, in order to effectively prevent recorded video that Caton phenomenon occurs, it may be necessary to
Further decrease the revolving speed of focusing motor 220.In other words, the distance moved according to needed for focus lens 210 falls into different
Distance segment needs the revolving speed of the focusing motor 220 using different shelves.Required movement distance farther out when, using lower turn
Speed.
It should be noted that the corresponding different rotating speeds of different distance section can by imaging device 200 in recorded video
It is detected to obtain in the process.For example, can control imaging device 200 is sequentially increased the distance moved needed for focus lens 210
So that it is fallen into different distance section and adjusts the revolving speed of focusing motor 220 respectively.Turn when the lucky unsteady flow of the video recorded is smooth
Speed can be determined that the corresponding revolving speed of the distance segment.The corresponding revolving speed of different distance section can also be in such a way that user inputs
It is determined.
