Abstract
The invention discloses a closed loop single drive automatic focusing device used by double cameras, which includes a shell, a double-lens supporting body, a drive induced magnet, a Hall sensor, a drive coil, a flexible circuit board and a base. The closed loop single drive automatic focusing device used by double cameras has the beneficial effects that a triangle visual photographic method of persons is gradually realized, the more accurate picture view-finding is realized, and the better picture quality is obtained. The triangle method which further uses the double cameras can realize a 3D technology similar to eyes. The double cameras use the automatic focusing device, and the development and application of the 3D technology can be more effectively realized. The closed loop single drive automatic focusing device can realize accurate double-lens driving, makes the focusing clearer, realizes more excellent view-finding range, and shoots high quality pictures.
Description
Technical field
The present invention relates to the closed loop list driving automatic focusing mechanism that dual camera uses, be especially used in being similar on the photographic means that eyes are the same.
Background technology
In the magnetic field that voice coil motor is a kind of utilization to be produced from the magnetic field of permanent-magnet steel and hot-wire coil conductor, interacting between magnetic pole produces the device of regular motion, is widely used in mobile phone camera.And in current used various photographic means, all adopt the frame mode of a photographic head, single photographic head can only shoot a range of photo every time, it is impossible to enough realize with eyes see completely the same；Following photo high-tech requirement and and the driving of following 3D technology under, the photographic means that simulating human eyes are the same steps into application, use by two photographic head, and the simulation of more advanced triangulation, the function found a view and focus that human eye is the same can be similar in simulated implementation place, it is achieved the scene that the outdoor scene taken pictures is seen with eyes is consistent.Relative to single photographic head, photo scope, definition captured by single photographic head are all not enough, and single photographic head also can only realize the shooting picture of 2D simultaneously.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides the closed loop list that a kind of dual camera rational in infrastructure uses to drive automatic focusing mechanism.
To achieve these goals, the technical scheme is that the closed loop list that a kind of dual camera uses drives automatic focusing mechanism, including
Base, as main body, is used for carrying miscellaneous part；
Double lens supporter, has double; two host cavity and is nested in base, is used for carrying two lens units, and carries lens unit action；
Drive induced magnet, be arranged on the side of double lens supporter, be used for driving double lens supporter action and sensing hall signal；
Drive coil, be arranged on base and drive position corresponding to induced magnet, be used for accepting signal and produce field drives and drive induced magnet action；
Hall element, is arranged on driving hub of a spool position, and corresponding with driving induced magnet center, is used for reading driving induced magnet sensing hall signal；
Flexible PCB, is arranged on outside driving coil, for transmission circuit control signal and hall signal；
Shell, embeds base, is used for closing the above-mentioned element assembled.
Further, described drive induced magnet both sides double lens supporter on be respectively equipped with the first slideway, the first obverse base of slideway is provided with the second slideway, the first slideway and the second corresponding slideway composition slide rail, is provided with ball in slide rail.
Further, described shell is provided with the doubled via corresponding with double; two host cavities of double lens supporter or double recess with base.
The invention has the beneficial effects as follows: realize the triangle vision method for imaging of personnel gradually, it is possible to achieve photo is found a view more accurately, and obtains better photographic quality；Trigonometry further with dual camera, it may be achieved be similar to the 3D technology of eyes, dual camera uses automatic focusing mechanism, it is possible to the more effective development realizing this type of technology and application.Closed loop list drives automatic focusing mechanism can realize twin-lens accurately and drives, and makes focusing become apparent from, it is achieved more excellent viewfinder range, shoots the photo of more high-quality.
