Abstract

An exemplary embodiment of the present invention includes a PCB (Printed Circuit Board) mounted with an image sensor, a holder member mounted at the PCB to support a lens module, movable lens concentrically arranged with the lens module, a first actuator compensating movement of an image captured by the image sensor by moving the movable lens, and a gyro sensor unit integrally formed with the first actuator to detect rotation of trajectory in response to movement of an electronic device mounted with the camera module.

First claim

The invention claimed is:

1. A camera module, the camera module comprising:
a PCB (Printed Circuit Board) mounted with an image sensor;
a holder member mounted at the PCB to support a lens module;
a movable lens concentrically arranged with the lens module;
a first actuator compensating movement of an image captured by the image sensor by moving the movable lens; and
a gyro sensor unit coupled with the first actuator by a first connection member to detect movement of an electronic device mounted with the camera module,
wherein the gyro sensor unit is disposed on the holder member, and
wherein the gyro sensor unit includes a body centrally formed with a through hole, a plurality of sensing lugs protrusively formed at a periphery of the body, and a sensing unit arranged at a surface corresponding to the plurality of sensing lugs.

2. The camera module of claim 1 , wherein the first connection member is formed with any one material of gold material and conductive material.

3. The camera module of claim 1 , wherein the through hole is formed with a diameter greater than a diameter of the lens module.

4. The camera module of claim 1 , wherein the body is provided in a shape of a ring and centrally formed with the through hole.

5. The camera module of claim 1 , wherein at least four sensing lugs are formed at the periphery of the body.

6. The camera module of claim 5 , wherein the plurality of sensing lugs is discretely arranged each at a predetermined same distance.

7. The camera module of claim 1 , wherein the sensing unit is arranged opposite to at least two surfaces of the sensing lugs.

8. The camera module of claim 1 , wherein the sensing unit is conductively connected to the PCB.

9. The camera module of claim 1 , wherein the first actuator is arranged at any one of an upper surface of the holder member, and between the holder member and the PCB.

10. The camera module of claim 1 , wherein the gyro sensor unit is disposed between the first actuator and the holder member.

11. A camera module, the camera module comprising:
a PCB (Printed Circuit Board) mounted with an image sensor;
a holder member mounted at the PCB to support a lens module;
a movable lens concentrically arranged with the lens module;
a second actuator adjusting a focus of an image captured on the image sensor by moving the movable lens; and
an acceleration sensor unit coupled with the second actuator by a second connection member to detect movement of an electronic device mounted with the camera module,
wherein the acceleration sensor is disposed on the holder member, and
wherein the acceleration sensor unit includes a ring-shaped body centrally formed at the acceleration sensor unit and formed with a diameter greater than a diameter of the lens module, a plurality of sensing lugs, at least four sensing lugs discretely arranged at a periphery of the body, each at a predetermined same distance, and a sensing unit arranged at a position corresponding to that of the plurality of sensing lugs and arranged opposite to at least two surfaces of the sensing lugs.

12. The camera module of claim 11 , wherein the second connection member is formed with any one material of gold material and conductive material.

13. The camera module of claim 11 , wherein the acceleration sensor unit is disposed between the second actuator and the holder member.
