A plurality of sensors 800 may be provided. For example, two sensors 800 may be provided to detect movement of the housing 310 in the x-axis and y-axis (the optical axis is the z-axis). The sensor 800 includes a first axis sensor 810 that detects movement of the magnet 320 in the first axis direction, and a second axis sensor 820 that detects movement of the magnet 320 in the second axis direction. ) may be included. In this case, the first axis and the second axis may be orthogonal to each other. Also, the first axis and the second axis may be orthogonal to the optical axis.

Hereinafter, the operation of the dual camera module according to the present embodiment will be described.

*First, the autofocus function of the dual camera module according to the present embodiment will be described. When power is supplied to the first coil 220a , the first coil 220a moves with respect to the magnet 320 by electromagnetic interaction between the first coil 220a and the magnet 320 . At this time, the first bobbin 210a to which the first coil 220a is coupled moves integrally with the first coil 220a. That is, the first bobbin 210a to which the first lens module is coupled is moved in the optical axis direction with respect to the housing 310 . Such movement of the first bobbin 210a results in the first lens module moving closer to or farther away from the first image sensor. It is possible to perform focus adjustment on . Meanwhile, the aforementioned focus adjustment may be automatically performed according to the distance of the subject.

Similarly, when power is supplied to the second coil 220b, the second coil 220b moves with respect to the magnet 320 by electromagnetic interaction between the second coil 220b and the magnet 320. . At this time, the second bobbin 210b to which the second coil 220b is coupled moves integrally with the second coil 220b. That is, the second bobbin 210b to which the second lens module is coupled is moved in the optical axis direction with respect to the housing 310 . Since this movement of the second bobbin 210b results in the second lens module moving closer to or moving away from the second image sensor, in this embodiment, power is supplied to the second coil 220b to supply the subject It is possible to perform focus adjustment on . Meanwhile, the aforementioned focus adjustment may be automatically performed 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 driving for the first lens module and the second lens module may be separately controlled.

A camera shake correction function of the dual camera module according to the present embodiment will be described. When power is supplied to the third coil 422 , the magnet 320 moves with respect 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 moves in a horizontal direction (a direction perpendicular to the optical axis) with respect to the base 430 . However, in this case, a tilt of the housing 310 with respect to the base 430 may be induced. Meanwhile, the bobbins 210a and 210b move integrally with the housing 310 with respect to the horizontal movement of the housing 310 . Accordingly, such movement of the housing 310 results in movement of the lens module coupled to the bobbins 210a and 210b in a direction parallel to the direction in which the image sensor is placed with respect to the image sensor. That is, in the present embodiment, power may be supplied to the third coil 422 to perform the hand shake correction function.

Meanwhile, in order to more precisely realize the hand shake correction function of the dual camera module according to the present embodiment, a hand shake correction feedback control may be performed. 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 moves relative 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 detect the amount or position of movement in the horizontal direction (x-axis and y-axis direction) of the housing 310 in this way, and transmit the sensed value to the controller. The control unit determines whether to perform additional movement with respect to the housing 310 based on the received sensing value. Since such a process occurs in real time, the hand shake correction function of the camera module according to the present embodiment can be more precisely performed through the hand shake correction feedback control.

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

13 is a conceptual diagram showing a modification of the present embodiment.

The dual camera module according to the modified example has a difference in the arrangement of the magnet 320 compared with the dual camera module according to the present embodiment described above. Therefore, hereinafter, the difference between the two embodiments will be mainly described, and the description in this embodiment may be analogously applied to the rest of the configuration.

* In a modified example, the magnet 320 may be disposed on the side surface of the housing 310 . It is different from that in this embodiment, the magnet 320 is disposed on the corner side of the housing 310 . Meanwhile, in the modified example, seven magnets 320 may be provided. The difference is that the magnet 320 in the present embodiment may be provided with eight corner magnets. In particular, the magnet 320 disposed between the first bobbin 210a and the second bobbin 210b by applying the seven magnets 320 in the modified example is AF of the first bobbin 210a and the second bobbin 210b. It can be used in common in driving. On the other hand, in the modified example, the arrangement of the N pole and the S pole may be different for the application of the seven magnets 320 . The magnet 320 facing the first bobbin 210a may have an N pole facing the first bobbin 210a. Also, the magnet 320 facing the second bobbin 210b may have an S pole facing the second bobbin 210b. Of course, the arrangement of the N pole and the S pole of the magnet 320 may be arranged opposite to the previous description.
