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 power is supplied to the AF coil part 220, the AF coil part 220 moves relative to the drive magnet part 320 by electromagnetic interaction between the AF coil part 220 and the drive magnet part 320 . At this time, the bobbin 210 to which the AF coil unit 220 is coupled moves integrally with the AF coil 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. Such movement of the bobbin 210 results in moving the lens module closer to the image sensor or moving away from the image sensor, so focus adjustment to the subject is performed.

On the other hand, autofocus feedback can be applied to achieve more precise realization of the autofocus function of the camera module according to the present embodiment. A voltage is induced in the sensing coil portion 910 mounted on the housing 310 by a high frequency current applied to the AF coil portion 220. When the driving current is applied to the AF coil part 220 and the bobbin 210 moves relative to the housing 310, the value of the voltage induced in the sensing coil part 910 can be changed. At this time, the supply of the high-frequency current to the AF coil section 220 can be performed at a predetermined time interval. Meanwhile, the voltage sensing unit senses a voltage value induced in the sensing coil unit 910 and transmits the sensed voltage value to the control unit. The control unit determines whether to perform additional movement to the bobbin 210 through the received voltage 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 OIS coil part 420, the driving magnet part 320 moves relative to the OIS coil part 420 by electromagnetic interaction between the OIS coil part 420 and the driving magnet part 320 . At this time, the housing 310 to which the driving magnet 320 is coupled moves integrally with the driving magnet 320. That is, the housing 310 is moved in the horizontal direction with respect to the base 500. At this time, the tilting of the housing 310 with respect to the base 500 may be induced. This movement of the housing 310 results in movement of the lens module with respect to the image sensor in a direction parallel to the direction in which the image sensor is placed (direction perpendicular to the optical axis of the lens module), so that the camera shake correction function is 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 OIS sensor 920 mounted on the base 500 senses the magnetic field of the drive magnet unit 320 fixed to the housing 310. On the other hand, when the housing 310 performs relative movement with respect to the base 500, the amount of the magnetic field sensed by the OIS sensor 920 changes. Meanwhile, the pair of OIS sensors 920 senses the movement amount or the position of the housing 310 in the horizontal direction (x-axis and y-axis direction) in the manner mentioned above, and transmits 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 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.
