It is right, and then target subject is shot again through imaging sensor 42.It should be noted that above-mentioned target subject is current
The speed of movement velocity is only that in contrast, what is indicated is the current kinetic speed of target subject and the size of pre-set velocity value
Relationship, it is to be understood that above-mentioned predeterminated frequency has corresponded to some pre-set velocity value, in the current kinetic speed of target subject
When degree is more than or equal to the pre-set velocity value, it is believed that target subject is high-speed motion；It is less than in the current kinetic speed of target subject
When the pre-set velocity value, it is believed that target subject is usual speed movement.
The camera module 40 carries out image by imaging sensor and catches when target subject keeps usual speed movement
It catches；When target subject carries out high-speed motion, automatically switches to and caught by dynamic visual sensor to carry out high-speed motion picture
It catches.Compared to traditional common camera, which can meet daily shooting demand and the user couple of user simultaneously
The demand of high-speed moving object shooting, and can make up for it the fuzzy defect of traditional camera shooting high-speed moving object.And phase
