Abstract
The present invention discloses a closed-loop single set control automatic focusing device used for dual cameras. The closed-loop single set control automatic focusing device used for the dual cameras comprises a pedestal and a flexible circuit board, the pedestal is equipped with two grooves, two lens supporting bodies are embedded in the two grooves respectively, and the flexible circuit board are connected with the two lens supporting bodies via two driving sensing devices respectively. The beneficial effects of the present invention are that the lenses of the dual cameras can be controlled to move individually, thereby realizing different focusing functions during a photography process; by a triangle vision photography method of people, the more accurate photography framing can be realized, and the better photography quality can be obtained; by utilizing a triangle method of the dual cameras, a 3D technology similar to the eyes can be realized, and by the dual-camera automatic focusing device, the development and application of the technology can be realized more effectively. By the closed-loop single set control automatic focusing device, two lens groups can carry out different functional framing respectively, and finally a clearer photograph can be synthesized, so that the module application is wider and diversified.
Description
Technical field
The present invention relates to dual camera uses closed loop list group to control automatic focusing mechanism, is 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 a kind of dual camera rational in infrastructure to use closed loop list group to control automatic focusing mechanism.
To achieve these goals, the technical scheme is that a kind of dual camera uses closed loop list group to control automatic focusing mechanism, including base and flexible PCB, described base is provided with two grooves, it is embedded with a lens supports body in two grooves respectively, connects respectively through a driving induction installation between described flexible PCB and two lens supports bodies.
Further, preferred as one, two driving induction installations are positioned at the same side.
Further, preferred as one, described driving induction installation includes hall sensing Magnet, Hall element, driving coil and drive magnet, described hall sensing Magnet is arranged on the inner side of the lens supports body drive surface of correspondence, and matched Hall element is arranged on the correspondence position on flexible PCB；Described drive magnet is arranged in the lens supports body drive surface of correspondence, and the matched coil that drives is arranged on the correspondence position on flexible PCB.
Further, preferred as one, the central shaft of two described lens supports bodies is parallel.
Further, preferred as one, it is provided with wood side-guide between described flexible PCB and two lens supports bodies, wood side-guide is provided with corresponding respectively with Hall element and driving coil dodges hole.
Further, preferred as one, described lens supports body is straight-line guidance ball set together with being provided with between wood side-guide and base respectively, and described twice straight-line guidance ball set lays respectively at the YZ plane both sides, lens supports body central shaft place of correspondence.
Further, preferred as one, described flexible PCB both wings are respectively equipped with circuit stiffening plate.
The invention has the beneficial effects as follows: the application can by carrying out independently moving control to the camera lens of dual camera, it is achieved the different focus function in electrophotographic process；By the triangle vision method for imaging of people, 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, and dual camera uses automatic focusing mechanism, it is possible to the more effective development realizing this type of technology and application.Closed loop list group controls automatic focusing mechanism and can realize two lens group and carry out different functions respectively and find a view, and the photo that final synthesis is apparent makes being more widely applied and variation of module.
