The sensor 800 may be placed on the base 430. The sensor 800 may be accommodated in the sensor coupling portion 433 formed on the upper surface of the base 430. Sensor 800 may be a Hall sensor. The sensor 800 may be a Hall IC (hall integrated circuit). The sensor 800 can detect the magnetic force of the magnet 320. That is, when the housing 310 moves, the sensor 800 can detect the amount of displacement of the housing 310 by detecting a change in magnetic force that changes due to the movement of the magnet 320. Sensors 800 may be provided in plural numbers. For example, two sensors 800 can be provided to detect movement of the housing 310 along 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 include. At this time, the first axis and the second axis may be orthogonal to each other. Additionally, the first axis and the second axis may be perpendicular to the optical axis.

Below, the operation of the dual camera module according to this embodiment will be described.

First, the autofocus function of the dual camera module according to this embodiment will be described. When power is supplied to the first coil 220a, the first coil 220a moves with respect to the magnet 320 due to 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 moves in the optical axis direction with respect to the housing 310. Since this movement of the first bobbin 210a results in the first lens module moving closer to or moving away from the first image sensor, in this embodiment, power is supplied to the first coil 220a to control the subject. You can perform focus control on . Meanwhile, the mentioned focus adjustment can be performed automatically depending on the distance of the subject.

Likewise, when power is supplied to the second coil 220b, the second coil 220b moves with respect to the magnet 320 due to 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 moves 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 control the subject. You can perform focus control on . Meanwhile, the mentioned focus adjustment can be performed automatically depending on the distance of the subject.

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

The image stabilization function of the dual camera module according to this embodiment will be described. When power is supplied to the third coil 422, the magnet 320 moves relative to the third coil 422 due to 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 as one piece with the magnet 320. That is, the housing 310 moves 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 move integrally with the housing 310 when the housing 310 moves in the horizontal direction. Accordingly, this movement of the housing 310 results in the lens module coupled to the bobbins 210a and 210b with respect to the image sensor moving in a direction parallel to the direction in which the image sensor is placed. That is, in this embodiment, the camera shake correction function can be performed by supplying power to the third coil 422.

Meanwhile, for more precise realization of the hand shake correction function of the dual camera module according to this embodiment, hand shake correction feedback control may be performed. The sensor 800 disposed on the base 430 detects 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 magnetic field detected by the sensor 800 changes. The first axis sensor 810 and the second axis sensor 820 detect the amount of movement or position of the housing 310 in the horizontal direction (x-axis and y-axis directions) in this manner and transmit the detection value to the control unit. The control unit determines whether to perform additional movement of the housing 310 based on the received detection value. Since this process occurs in real time, the camera module's camera module according to this embodiment's camera shake correction function can be performed more precisely through hand shake correction feedback control.

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

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

The dual camera module according to the modified example has a difference in the arrangement of the magnet 320 compared to the dual camera module according to the present embodiment described above. Therefore, the following will focus on explaining the differences between the two embodiments, and the description in this embodiment can be applied by analogy to the remaining configurations.

In a modified example, the magnet 320 may be placed on the side of the housing 310. This is different from the case where the magnet 320 is disposed on the corner side of the housing 310 in this embodiment. Meanwhile, in a modified example, seven magnets 320 may be provided. This is different from the magnet 320 in this embodiment, which may be provided as 8 corner magnets. In particular, in the modified example, by applying seven magnets 320, the magnets 320 disposed between the first bobbin (210a) and the second bobbin (210b) are used to control the AF of the first bobbin (210a) and the second bobbin (210b). It can be used for common use in driving. Meanwhile, in a modified example, the arrangement of the N and S poles may be different to apply the seven magnets 320. The N pole of the magnet 320 facing the first bobbin 210a may be directed toward the first bobbin 210a. Additionally, the S pole of the magnet 320 facing the second bobbin 210b may be directed toward the second bobbin 210b. Of course, the arrangement of the N and S poles of the magnet 320 may be arranged opposite to the previous description.
