Description

Technical Field [0001] The present invention relates to a dual camera and a mobile phone using the dual camera.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone dual camera composed of a wide camera and a telecamera, and a cellular phone dual camera using the same. More particularly, the present invention relates to a cellular phone having a mobile phone capable of improving driving efficiency, A dual camera and a mobile phone dual camera using the same.

In general, among the functions of dual cameras, the zoom function places each camera in Wide and Tele, and the EFL deviation of Wide and Tele can be converted into Zoom Ratio.

The larger the deviation of the EFL, the larger the zoom magnification, and the user can take a clearer picture of the subject at a greater distance.

In particular, since a telescopic lens has a long length, it is physically difficult to mount it on a mobile device such as a smart phone. In order to overcome this problem, the telescopic lens has to be folded by using a prism and a mirror .

In addition, in order to make the thickness of the smartphone slimmer, the refraction type camera can not be realized in the form of a general square, and the shape of the actuator for AF is limited to a rectangular shape.

FIG. 1 is a view showing a schematic assembling process of a conventional dual camera including a wide camera and a tele camera.

Referring to FIG. 1, the shield is fastened to the circumferential surface of the actuator housing in a state where all the actuator parts are installed in the actuator housing.

Then, the shading plate is assembled with the prism and the lens inserted, the IR filter, the sensor bracket and the sensor are assembled, and the active alignment (AA), which is a process of aligning the optical axis of the sensor and the lens, is adjusted.

Then, the wide camera is assembled to one side of the actuator housing. In order to prevent the wide camera from being separated from the wide camera, the wide support which is coupled to the actuator housing and surrounds the wide camera must be assembled.

In addition, after assembling the wide camera, it is necessary to adjust the relative alignment (RA) in order to align the optical axis of the camera and the camera in parallel, and this procedure takes more than several tens of seconds.

2. Description of the Related Art [0002] Conventionally, a conventional lens transfer unit includes a carrier for fixing and transferring a lens, and a ball guide for supporting the lens by a plurality of balls. In the same direction as the ball is supported, And is moved back and forth in the optical axis direction of the lens by the attracting force of the magnet and the back yoke (pole) in the same direction as the driving unit constituted by the lens.

That is, since the driving unit for transporting the carrier is constructed in a laminated structure, it is inevitable that the driving unit is made to have a certain thickness or more.
