It should be noted that ordinary movement speed and high-speed motion are only that in contrast, expression is working as target subject
The size relation of preceding movement velocity and preset value, such as in the present embodiment, the current kinetic speed of target subject is being less than
It is considered as ordinary movement speed when preset value；The current kinetic speed of target subject is considered as high speed when being greater than or equal to preset value
Movement.
Referring to Fig. 7, in some embodiments, can determine camera module according to the movement velocity of target subject
Operating mode.Specifically, image processing module can judge target subject according to the adjacent two field pictures of imaging sensor
Current kinetic speed, at this point, step S101 may include step S1~step S3.
Step S1: the adjacent two field pictures of imaging sensor are obtained.
In the present embodiment, imaging sensor is to obtain image by the method for frame refreshing, passes through the frame per second that setting is fixed, figure
As sensor according to certain interval time continuously to image processing module export picture signal, image processing module is when adjacent
Carving the picture signal obtained is the adjacent two field pictures of imaging sensor.
S2: determine that target subject in the relative position of adjacent two field pictures, and calculates target subject in adjacent two frames figure
The relative position of picture is poor.
When obtaining image, luminous intensity of the static target in adjacent two field pictures will not become imaging sensor
Luminous intensity of the target changed, and moved in adjacent two field pictures can change.Image processing module obtains adjacent two frames figure
As after, identical object of reference static in adjacent two field pictures is determined according to the comparison of the luminous intensity of adjacent two field pictures, and according to ginseng
It determines the relative position of target subject and identical object of reference in adjacent two field pictures respectively according to object, and then determines target subject in phase
The relative position of adjacent two field pictures is poor.
S3: poor depending on the relative position and adjacent two field pictures time differences calculate the current kinetic speed of target subject.
Imaging sensor refreshes according to fixed frame per second, it is possible thereby to determine the time interval of adjacent two field pictures, namely
The time difference of adjacent two field pictures, image processing module is according to target subject in the relative position of adjacent two field pictures difference and phase
The time difference of adjacent two field pictures calculates the current kinetic speed of target subject with this.
Further, after image processing module calculates the current kinetic speed of target subject, by current kinetic speed
Compared with speed preset value, if the current kinetic speed of target subject is less than speed preset value, it is determined that the Working mould of camera
Formula is first mode.If the current kinetic speed of target subject is not less than speed preset value namely the current kinetic of target subject
Speed is greater than or equal to speed preset value, it is determined that the operating mode of camera is second mode.
In some embodiments, it can be taken the photograph according to the received control instruction of specified module institute of electronic equipment to determine
As the operating mode of head mould group.Specifically, execution module according to user execute operation and generate execute instruction, which refers to
The operating mode for controlling camera module is enabled, at this point, step S101 may include step: obtaining execution module according to user

Execute instruction the expectation information that can carry user.For example, user's expectation obtains mesh shot by dynamic visual sensor at this time
Target image, although target subject is not in high-speed motion state at this time.User passes through gesture, touch-control etc. in display panel
After mode carries out desired operation, execution module can be executed instruction according to desired operation generation is corresponding, and wherein the execution refers to
Enable the expectation information " image of target subject is obtained by dynamic visual sensor " for carrying user.
Step S102: according to operating mode, the working condition of driving assembly is controlled.Further, the driving group is controlled
When the working condition of part, if the operating mode is first mode, controls the driving component and keep described image sensor
It is opposite with the dynamic visual sensor；If the operating mode is second mode, control described in the driving component driving
Imaging sensor far from the dynamic visual sensor, with allow the dynamic visual sensor directly with the lens assembly phase
It is right.
Under first mode, since target subject is not high-speed motion, so obtaining target subject by imaging sensor
Picture can meet the needs of users, the driving assembly of image processing module control at this time keeps imaging sensor and dynamic vision
Sensor is opposite, to obtain the motion picture of target subject by imaging sensor.
Further, when first mode triggers, if imaging sensor and the initial position of dynamic visual sensor are phase
To state, then image processing module control driving assembly keeps imaging sensor opposite with dynamic visual sensor；If image passes
Sensor and the initial position of dynamic visual sensor are not relative status, then image processing module control driving assembly drives image
Sensor so that imaging sensor is opposite with dynamic visual sensor, and then keeps image sensing close to dynamic visual sensor again
Device is opposite with dynamic visual sensor.
Under second mode, target subject is high-speed motion, is transported by the high speed that dynamic visual sensor captures target subject
Animation face, can make to capture picture is more clear, so needing imaging sensor being switched to dynamic visual sensor at this time.
Image processing module can control driving assembly driving imaging sensor far from dynamic visual sensor at this time, and dynamic vision is allowed to pass
Sensor is directly opposite with lens assembly, to pass through the high-speed motion picture of dynamic visual sensor target subject.
Further, when second mode triggers, if imaging sensor and the initial position of dynamic visual sensor are phase
To state, then image processing module control driving assembly driving imaging sensor makes dynamic vision far from dynamic visual sensor
Sensor is directly opposite with lens assembly；If imaging sensor and the initial position of dynamic visual sensor are not relative status,
Namely original state is that dynamic visual sensor is directly opposite with lens assembly, then image processing module control driving assembly is protected
Hold the current relative position state of imaging sensor and dynamic visual sensor.
