The control unit is an autofocus feedback control and / or an image stabilization feedback control. It is possible to control.

[0109] The camera device 10A according to this embodiment can be used as a mobile camera. That is, it can be distinguished from a camera device for digital camera application. When miniaturizing for laser applications, the driving force of the VCM decreases relatively, so the three operations ( To realize X-Shift, Y-Shift, Z-Rotation (Roll) However, there is a problem in that the current consumption increases.

[0110] The magnets 320 and coils 310 are rotated 90 degrees at each corner of the base 410. The magnet 320 and the coil 310 positioned diagonally opposite each other are assembled in the same direction. In this case, when the image sensor 444 is shift-driven, the load in the same direction can be shifted. When the z-axis is rotated, two pairs of torques are generated with opposite forces. This can be done.

[0111] In this embodiment, the four coils located at the corners have independent current inputs. If necessary, the power terminal of the coil 310 is separated into four channels. In other words, this embodiment can have a system that controls the same magnetic flux direction magnets. It may include a diagonal arrangement structure and a four coil individual current input structure.

[0112] This embodiment can include two pairs of torque generating structures (increasing the rotational moment). This structure generates a torque of X, which is capable of generating a higher rotational moment than conventional models. -Three modes of operation: Shift, Y-Shift, Z-Rotation (Roll) It is possible to reduce the total current consumption.

[0113] The simulation results for the camera device according to this embodiment are as follows: The formula is as follows: 'Rotational moment = torque * torque distance = (electromagnetic force * input current When the current is multiplied by the center distance of the magnets 320, the center of the camera device 10A according to this embodiment is When 50mA is applied to the coil 310 as an input current, the It was confirmed that a rotational moment of 2.14 mm x 2 = 114.1 mN.mm was generated. .

[0114] In this embodiment, image stabilization for the image sensor 444 and image stabilization for the corresponding lens are performed. As an example, the MEMS actuator 22 may be used to correct the image stabilization. When image stabilization is performed using only the liquid lens 220a, the image obtained by the image sensor 444 is Positive (+) distortion can occur at the edges of the image being scanned. When image stabilization is performed by moving only the image sensor 444, the image obtained by the image sensor 444 is In this embodiment, negative (-) distortion may occur at the edge of the image. Image stabilization for the sensor 444 and the MEMS actuator 220 or the liquid lens 220 Combined with image stabilization, distortion at the edges of the image is minimized. In this embodiment, the liquid lens 220a is used to move the liquid crystal panel 210. The lens performs image stabilization and the image sensor 444 is moved accordingly. This allows the lens and image sensor 444 to move together. However, in this embodiment, the camera can provide a level of image stabilization corresponding to the module movement method. In the embodiment, the MEMS actuator 220 or the liquid lens 220a has an AF function. Alternatively, only the optical axis may be provided and the OIS function may be performed by moving the image sensor 444.
