During little focal length threshold value, this terminal can be by this photographic head during reducing the focal length of photographic head
Focal length compares with this minimum focus threshold value, when detecting that the focal length of photographic head is equal to this minimum focus threshold value
Time, then stop focusing and reduce；Or, when the discharging of the coke away from increase based on bending stress parameter determination,
Gradually increasing when front focal length this photographic head, the focal length after this photographic head adjusts is more than or equal to
During big focal length threshold value, this terminal can be by this photographic head during increasing the focal length of photographic head
Focal length compares with this maximum focal length threshold value, when detecting that the focal length of this photographic head is equal to this maximum focal length threshold
During value, then stop focusing and increase.
