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

First, the autofocus function of the camera module according to the present embodiment will be described. When the coil of the first driving unit 220 is supplied with power, the first driving unit 220 is driven by the second driving unit 320 by electromagnetic interaction between the magnets of the first driving unit 220 and the second driving unit 320, As shown in FIG. At this time, the bobbin 210 to which the first driving unit 220 is coupled moves integrally with the first driving unit 220. That is, the bobbin 210 coupled to the inner side of the lens module moves up and down with respect to the housing 310. This movement of the bobbin 210 results in movement of the lens module toward or away from the image sensor. Thus, in this embodiment, power is supplied to the coil of the first driving unit 220 to adjust the focus Can be performed.

On the other hand, in the camera module according to the present embodiment, autofocus feedback can be applied for more accurate realization of the autofocus function. The first sensor, which is disposed in the housing 310 and is provided as a hall sensor, senses the magnetic field of the sensing magnet 715 fixed to the bobbin 210. Accordingly, when the bobbin 210 performs relative movement with respect to the housing 310, the amount of the magnetic field sensed by the first sensor changes. The first sensor senses the movement amount of the bobbin 210 in the z-axis direction or the position of the bobbin 210 in this manner, and transmits the detection value to the control unit. The control unit determines whether to perform an additional movement with respect to the bobbin 210 through the received sensing value. Since such a process is generated in real time, the autofocus function of the camera module according to the present embodiment can be performed more precisely through autofocus feedback.

The camera shake correction function of the camera module according to the present embodiment will be described. When power is supplied to the coil of the third driving part 420, the second driving part 320 is moved to the third driving part 420 by the electromagnetic interaction of the magnets of the third driving part 420 and the second driving part 320 Movement. At this time, the housing 310 coupled with the second driving unit 320 moves integrally with the second driving unit 320. That is, the housing 310 is moved in the horizontal direction with respect to the base 500. However, at this time, the housing 310 may be tilted with respect to the base 500. At this time, the bobbin 210 also moves integrally with the housing 310. Accordingly, since the movement of the housing 310 is a result of moving the lens module in a direction parallel to the direction in which the image sensor is placed with respect to the image sensor, power is supplied to the coil of the third driver 420 in this embodiment And the camera shake correction function can be performed.

Meanwhile, the camera-shake correction feedback may be applied for more precise realization of the camera-shake correction function of the camera module according to the present embodiment. The pair of second sensor units 720 mounted on the base 500 and provided as hall sensors sense the magnetic field of the magnet of the second driving unit 320 fixed to the housing 310. Therefore, when the housing 310 performs relative movement with respect to the base 500, the amount of the magnetic field sensed by the second sensor unit 720 changes. The pair of second sensor units 720 senses the movement amount or position of the housing 310 in the horizontal direction (x-axis and y-axis direction) in this way and transmits the sensed 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 the above process is performed in real time, the camera shake correction function of the camera module according to the present embodiment can be performed more precisely with the camera shake correction feedback.

That is, within the scope of the present invention, all of the components may be selectively coupled to one or more of them. Furthermore, the terms "comprises", "comprising", or "having" described above mean that a component can be implanted unless otherwise specifically stated, But should be construed as including other elements. All terms, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. Commonly used terms, such as predefined terms, should be interpreted to be consistent with the contextual meanings of the related art, and are not to be construed as ideal or overly formal, unless expressly defined to the contrary.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
