[0071] The "auto focus function" used hereinafter may be defined as a function of adjusting the focal length relative to an object by adjusting the distance to the image sensor by movement of the lens module in the optical axis direction in response to the distance to the object, thereby obtaining a clear image of the object on the image sensor.

[0079] Hereinafter, a configuration of a dual camera module according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

[0080] Figure 1 is a perspective view of a dual camera module according to an exemplary embodiment of the present invention.

[0081] A dual camera module according to an exemplary embodiment of the present invention may include a first camera module and a second camera module.

[0082] The first camera module may be an AF feedback driven camera module having an AF feedback function. In this case, the first camera module may be referred to as an "AF feedback camera module". Alternatively, the first camera module may be arranged with an AF driven camera module having an auto focus function. In this case, the first camera module may be referred to as an "AF camera module". Alternatively, the first camera module may be formed as an OIS driven camera module.

[0083] The first camera module may include a first lens driving device 1000, a first lens module (not shown), a first infrared filter (not shown), a first PCB (printed circuit board) 1001, a first image sensor (not shown), and a first controller (not shown).

[0084] The first lens module may include a lens and a lens barrel. The first lens module may include one or more lenses (not shown) and a lens barrel accommodating one or more lenses. However, an element of the first lens module is not limited by the lens module, and any holder structure capable of supporting one or more lenses will be satisfied. The first lens module may move with the first lens drive device 1000 by being coupled to the first lens drive device 1000. The first lens module may be coupled to the interior of the first lens drive device 1000. The first lens module may be threadedly coupled to the first lens drive device 1000. The first lens module may be coupled to the first lens drive device 1000 by an adhesive (not shown). At the same time, the light that has passed through the first lens module may be irradiated on the first image sensor.

[0085] The first infrared filter can be used to prevent light in the infrared range from entering the first image sensor. The first infrared filter can be placed between the first lens module and the first image sensor. The first infrared filter can be arranged at a holder member (not shown) arranged separately from the first base 1500. However, the first infrared filter can be installed on an opening 1510 formed at the center of the first base 1500. The first infrared filter can be formed by a film material or a glass material. The first infrared filter can be formed by allowing an infrared cut-off coating material to be coated on a plate-shaped filter such as an imaging plane protective cover glass or cover glass. The first infrared filter can be an infrared cut-off filter or an infrared absorption filter.

[0086] The first PCB 1001 may support the first lens driving device 1000. The first PCB 1001 may be mounted with a first image sensor. For example, the first PCB 1001 may be arranged with a first image sensor at the inner side of the upper side, and the first PCB 1001 may be arranged with a first sensor holder 1002 at the outer side of the upper side. The first lens driving device 1000 may be arranged on the upper side of the first sensor holder 1002. The first sensor holder 1002 may be formed integrally with the first base 1500. Alternatively, the first PCB 1001 may be arranged with the first lens driving device 1000 at the outer side of the upper side, and the first PCB 1001 may be arranged with a first image sensor at the inner side of the upper side. Through the structure, the light of the first lens module that has passed through the interior of the first lens driving device 1000 may be irradiated on the first image sensor mounted on the first PCB 1001. The first PCB 1001 may supply power to the first lens driving device 1000. Meanwhile, the first PCB 1001 may be provided with a first controller so as to control the first lens driving device 1000. The first PCB 1001 may be formed integrally with the second PCB 2001. The first PCB 1001 and / or the second PCB 2001 may be a substrate of an optical device. Each of the first PCB 1001 and the second PCB 2001 may include a terminal so as to be connected to the outside.

[0087] The first image sensor may be mounted on the first PCB 1001. The first image sensor may be arranged to match the first lens module through the optical axis, and through this structure, the first image sensor may obtain the light that has passed through the first lens module. The first image sensor may output the irradiated light in the form of an image. The first image sensor may be, for example, a CCD (charge coupled device), a MOS (metal oxide semiconductor), a CPD, and a CID. However, the type of the first image sensor is not limited thereto.

[0088] The first controller may be mounted on the first PCB 1001. The first controller may be arranged at the outer side of the first lens driving device 1000. However, the first controller may be arranged at the inner side of the first lens driving device 1000. The first controller may control the direction, intensity and amplitude of the current supplied to each element forming the first lens driving device 1000. The first controller may perform the auto focus function of the first camera module by controlling the first lens driving device 1000. That is, the first controller may move the first lens module along the optical axis direction by controlling the first lens driving device 1000. In addition, the first controller may perform feedback control of the auto focus function. More specifically, the first controller may control the current or power supplied to the first coil 1220 by receiving the position of the first coil frame 1210 detected by the first Hall sensor 1430 to provide a more accurate auto focus function. The first controller may perform feedback control of the auto focus function and the OIS function.
