Thus, in this embodiment, power is supplied to the first coil 220a, It is possible to perform focus adjustment on the image. On the other hand, the aforementioned focus adjustment can be performed automatically according to the distance of the subject.

Similarly, when power is supplied to the second coil 220b, the second coil 220b moves relative to the magnet 320 by electromagnetic interaction between the second coil 220b and the magnet 320 . At this time, the second bobbin 210b coupled with the second coil 220b moves integrally with the second coil 220b. That is, the second bobbin 210b coupled with the second lens module moves in the direction of the optical axis with respect to the housing 310. This movement of the second bobbin 210b results in movement of the second lens module toward or away from the second lens module. Thus, in this embodiment, power is supplied to the second coil 220b, It is possible to perform focus adjustment on the image. On the other hand, the aforementioned focus adjustment can be performed automatically according to the distance of the subject.

In this embodiment, since the current supply to the first coil 220a and the second coil 220b is separately controlled, the AF drive to the first lens module and the second lens module can be separately controlled.

The camera-shake compensation function of the dual camera module according to the present embodiment will be described. When the third coil 422 is supplied with power, the magnet 320 moves relative to the third coil 422 by electromagnetic interaction between the third coil 422 and the magnet 320. At this time, the housing 310 to which the magnet 320 is coupled moves integrally with the magnet 320. That is, the housing 310 is moved in the horizontal direction (direction perpendicular to the optical axis) with respect to the base 430. However, at this time, the housing 310 may be tilted with respect to the base 430. Meanwhile, the bobbins 210a and 210b are moved integrally with the housing 310 with respect to the horizontal movement of the housing 310. Thus, this movement of the housing 310 results in a lens module coupled to the bobbin 210a, 210b with respect to the image sensor moving in a direction parallel to the direction in which the image sensor lies. That is, in this embodiment, power is supplied to the third coil 422 to perform the camera shake correction function.

Meanwhile, the camera shake correction feedback control can be performed for more precise realization of the shake correction function of the dual camera module according to the present embodiment. The sensor 800 disposed on the base 430 senses the magnetic field of the magnet 320 disposed on the housing 310. Accordingly, when the housing 310 performs a relative movement with respect to the base 430, the amount of the magnetic field sensed by the sensor 800 changes. The first axis sensor 810 and the second axis sensor 820 sense the movement amount or position in the horizontal direction (x axis and y axis direction) of the housing 310 in this way and transmit the sensing value to the control unit. The control unit determines whether to perform the additional movement to the housing 310 through the received sensing value. Since such a process is generated in real time, the camera shake correction function of the camera module according to the present embodiment can be performed more precisely through the camera shake correction feedback control.

Hereinafter, a configuration of a dual camera module according to a modification of the embodiment will be described with reference to the drawings.

13 is a conceptual diagram showing a modification of this embodiment.

The dual camera module according to the modification has a difference in arrangement of the magnets 320 as compared with the dual camera module according to the present embodiment described above. Therefore, the differences between the embodiments will be mainly described below, and the remainder of the configuration can be applied to the description in the present embodiment.

In an alternative embodiment, the magnet 320 may be disposed on the side of the housing 310. The magnet 320 is disposed on the corner side of the housing 310 in this embodiment. On the other hand, in the modified example, the number of the magnets 320 may be seven. This embodiment differs from the embodiment in that the magnet 320 can be provided with eight corner magnets. Particularly, in the modification, the magnets 320 disposed between the first bobbin 210a and the second bobbin 210b by the application of the seven magnets 320 are disposed in the vicinity of the first bobbin 210a and the second bobbin 210b, It can be used in common for driving. On the other hand, in the modified example, the arrangement of N poles and S poles can be changed for applying seven magnets 320. The magnet 320 facing the first bobbin 210a may face the first bobbin 210a with the N pole. Also, the S pole of the magnet 320 facing the second bobbin 210b may face the second bobbin 210b. Of course, the arrangement of the N pole and the S pole of the magnet 320 may be reversed from the above description.
