Abstract

A lens device includes a housing configured to maintain a lens. The lens device also includes a maintaining structure disposed at an exterior surface of the housing surrounding the lens, and configured to detachably maintain a peripheral device. The lens device further includes one or more electric contacts disposed on the exterior surface of the housing between the lens and the maintaining structure, and configured to electrically connect with the peripheral device.

First claim

What is claimed is:

1. A lens device, comprising:
a housing configured to maintain a lens, the lens being configured to let incident light pass through to an image sensor, wherein the image sensor and a first portion of the lens are disposed within the housing and a second portion of the lens protrudes out of the housing;
a maintaining structure disposed at an exterior surface of the housing and surrounding the second portion of the lens, the maintaining structure being configured to detachably maintain a peripheral device comprising a light source; and
one or more electric contacts disposed on the exterior surface of the housing between the lens and the maintaining structure and configured to electrically connect with the peripheral device.

2. The lens device of claim 1 , wherein the one or more electric contacts are disposed at one or more locations that contact one or more electric contacts of the peripheral device maintained by the maintaining structure.

3. The lens device of claim 2 , wherein the maintaining structure detaches or mounts the peripheral device relative to the exterior surface of the housing through sliding or rotating the peripheral device relative to the exterior surface of the housing.

4. The lens device of claim 3 , wherein
the one or more electric contacts comprise multiple electric contacts, and the multiple electric contacts are disposed on the exterior surface of the housing along a sliding direction or a rotating direction of the peripheral device.

5. The lens device of claim 3 , wherein the peripheral device comprises:
a load to which an electric power is provided through the one or more electric contacts.

6. The lens device of claim 5 , wherein the peripheral device covers the lens.

7. The lens device of claim 3 , wherein the peripheral device covers the lens.

8. The lens device of claim 7 ,
wherein the peripheral device seals the second portion of the lens protruding out of the housing with a sealing component that seals a space between an interior surface of the peripheral device and the exterior surface of the housing,
wherein a periphery of the maintaining structure is disposed outside a periphery of the second portion of the lens protruding out of the housing, and
wherein the sealing component coincides with the periphery of the maintaining structure.

9. The lens device of claim 2 , wherein the peripheral device comprises:
a load to which an electric power is provided through the one or more electric contacts.

10. The lens device of claim 9 , wherein the peripheral device covers the lens.

11. The lens device of claim 2 , wherein the peripheral device covers the lens.

12. The lens device of claim 11 ,
wherein the peripheral device seals the second portion of the lens protruding out of the housing with a sealing component that seals a space between an interior surface of the peripheral device and the exterior surface of the housing,
wherein a periphery of the maintaining structure is disposed outside a periphery of the second portion of the lens protruding out of the housing, and
wherein the sealing component coincides with the periphery of the maintaining structure.

13. The lens device of claim 1 , wherein the maintaining structure detaches or mounts the peripheral device relative to the exterior surface of the housing through sliding or rotating the peripheral device relative to the exterior surface of the housing.

14. The lens device of claim 13 , wherein
the one or more electric contacts comprise multiple electric contacts, and
the multiple electric contacts are disposed on the exterior surface of the housing along a sliding direction or a rotating direction of the peripheral device.

15. The lens device of claim 13 , wherein the peripheral device comprises:
a load to which an electric power is provided through the one or more electric contacts.

16. The lens device of claim 15 , wherein the peripheral device covers the lens.

17. The lens device of claim 13 , wherein the peripheral device covers the lens.

18. The lens device of claim 17 ,
wherein the peripheral device seals the second portion of the lens protruding out of the housing with a sealing component that seals a space between an interior surface of the peripheral device and the exterior surface of the housing,
wherein a periphery of the maintaining structure is disposed outside a periphery of the second portion of the lens protruding out of the housing, and
wherein the sealing component coincides with the periphery of the maintaining structure.

19. The lens device of claim 1 , wherein the peripheral device comprises:
a load to which an electric power is provided through the one or more electric contacts.

20. The lens device of claim 19 , wherein the peripheral device covers the lens.

21. The lens device of claim 20 ,
wherein the peripheral device seals the second portion of the lens protruding out of the housing with a sealing component that seals a space between an interior surface of the peripheral device and the exterior surface of the housing,
wherein a periphery of the maintaining structure is disposed outside a periphery of the second portion of the lens protruding out of the housing, and
wherein the sealing component coincides with the periphery of the maintaining structure.

22. The lens device of claim 1 , wherein the peripheral device covers the lens.

23. The lens device of claim 22 ,
wherein the peripheral device seals the second portion of the lens protruding out of the housing with a sealing component that seals a space between an interior surface of the peripheral device and the exterior surface of the housing,
wherein a periphery of the maintaining structure is disposed outside a periphery of the second portion of the lens protruding out of the housing, and
wherein the sealing component coincides with the periphery of the maintaining structure.

24. The lens device of claim 23 , wherein the maintaining structure comprises the sealing component.

25. The lens device of claim 23 , wherein the housing maintains the second portion of the lens on the exterior surface of the housing.

26. The lens device of claim 23 , wherein the maintaining structure is disposed on the exterior surface so as to surround the second portion of the lens.

27. The lens device of claim 1 , wherein the housing maintains the second portion of the lens on the exterior surface of the housing.

28. The lens device of claim 1 , wherein the maintaining structure is disposed on the exterior surface so as to surround the second portion of the lens.

29. An imaging device, comprising:
a lens device comprising:
a housing configured to maintain a lens;
a maintaining structure disposed at an exterior surface of the housing and surrounding a second portion of the lens, the maintaining structure being configured to detachably maintain a peripheral device;
one or more electric contacts disposed on the exterior surface of the housing between the lens and the maintaining structure and configured to electrically connect with the peripheral device; and
an image sensor configured to convert an optical image generated by the lens into an electric signal,
wherein the image sensor and a first portion of the lens are disposed within the housing and the second portion of the lens protrudes out of the housing; and
