Abstract

A camera device is provided, including a liquid lens, a deforming member, and a first driving module. The deforming member is disposed adjacent to the liquid lens, and the first driving module can generate relative motion between the liquid lens and the deforming member. In response to the adjustment of the distance between the liquid lens and the deforming member, the deforming member deforms the liquid lens.

Claims (20)

1. A camera device, comprising:

a liquid lens;

a deforming member, disposed adjacent to the liquid lens and configured to deform the liquid lens; and

a first driving module, configured to drive the liquid lens or the deforming member to move along an optical axis of the liquid lens, and comprising a first electromagnetic driving member and a second electromagnetic driving member corresponding to each other, wherein in response to the adjustment of the distance between the liquid lens and the deforming member, the deforming member deforms the liquid lens, wherein the first electromagnetic driving member and the second electromagnetic driving member are separated and not overlapped with each other in a direction parallel to the optical axis.

2. The camera device as claimed in claim 1 , wherein the dimensions of the deforming member are less than the dimensions of the liquid lens.

3. The camera device as claimed in claim 1 , wherein the deforming member has an annular structure.

4. The camera device as claimed in claim 1 , wherein the camera device further comprises a fixed portion and a movable portion, wherein the liquid lens is disposed on the fixed portion, and the first electromagnetic driving member and the second electromagnetic driving member are respectively disposed on the fixed portion and the movable portion.

5. The camera device as claimed in claim 1 , wherein the lower surface of the deforming member is situated on a first plane, and the lower surface of the liquid lens is situated on a second plane, wherein the first driving module can drive the deforming member to rotate and make the first plane and the second plane interlace.

6. The camera device as claimed in claim 5 , wherein the first driving module comprises at least two first electromagnetic driving members and at least two second electromagnetic driving members corresponding to the first electromagnetic driving members, and the deforming member is disposed between the first electromagnetic driving members.

7. The camera device as claimed in claim 6 , wherein the first electromagnetic driving members are electrically independent.

8. The camera device as claimed in claim 1 , wherein the first driving module can drive the deforming member to move along a direction that is perpendicular to the optical axis of the liquid lens relative to the liquid lens.

9. The camera device as claimed in claim 8 , wherein the camera device further comprises a fixed portion and at least one suspension structure, the liquid lens is disposed on the fixed portion, and the suspension structure is connected to the fixed portion and the deforming member.

10. The camera device as claimed in claim 1 , wherein the camera device further comprises a fixed portion and a second driving module, and the second driving module can drive the liquid lens to move along a direction that is perpendicular to the optical axis of the liquid lens relative to the fixed portion.

11. The camera device as claimed in claim 1 , wherein the camera device further comprises a lens module, disposed above or below the liquid lens.

12. The camera device as claimed in claim 11 , wherein the deforming member is formed on the lens module.

13. The camera device as claimed in claim 1 , wherein the camera device further comprises a reflective structure, and the liquid lens, the deforming member, and the first driving module are disposed on the reflective structure.

14. The camera device as claimed in claim 13 , wherein the liquid lens, the deforming member, and the first driving module are disposed on a reflective surface of the reflective structure.

15. The camera device as claimed in claim 13 , wherein the reflective structure comprises a prism, and the liquid lens, the deforming member, and the first driving module are disposed on the prism.

16. The camera device as claimed in claim 1 , wherein the camera device further comprises another deforming member, and the deforming member and the other deforming member are disposed on opposite sides of the liquid lens.

17. The camera device as claimed in claim 16 , wherein the dimensions of the deforming member are different from the dimensions of the other deforming member.
