Abstract

The disclosed teachings include a 360-degree camera accessory mountable on a smartphone. The 360-degree camera accessory includes a camera module disposed partially within the camera accessory, where the camera module including an optical lens configured to capture an image of a scene. The 360-degree camera accessory also includes a rigid structure disposed within the accessory to support the camera module, and a deformable structure disposed between a camera barrel that surrounds the optical lens of the camera module and the rigid structure. The deformable structure can compensate for movement of the camera module to improve image capturing of the scene.

Claims

1. A camera accessory comprising:

a camera module disposed at least partially within the camera accessory and including an optical element configured to capture an image of a scene;

a camera barrel that at least partially surrounds the camera module to position the camera module relative to the camera accessory;

a rigid structure within the camera accessory and disposed behind the camera module; and

a deformable structure coupled between the camera barrel and the rigid structure to maintain the position of the camera module by compensating for displacement of the camera module relative to the camera accessory.

2. The camera accessory of claim 1 further comprises:

a mounting structure configured to mount the camera accessory on a smartphone.

3. The camera accessory of claim 1, wherein a field of view of the camera accessory is 360-degrees.

4. The camera accessory of claim 1, wherein a field of view of the camera module is at least 180 degrees.

5. The camera accessory of claim 1, wherein the optical element is an optical lens.

6. The camera accessory of claim 5, wherein the camera module has a camera sensor disposed behind the camera module suspended from the rigid structure by the deformable structure.

7. The camera accessory of claim 1 further comprising:

a plurality of camera modules including the camera module; and

a plurality of deformable structures including the deformable structure, wherein each deformable structure coupled between a respective camera barrel and the rigid structure such that each deformable structure maintains placement of each camera module by compensating for displacement of the camera module relative to the camera accessory.

8. The camera accessory of claim 7, wherein the plurality of camera modules is a plurality of opposite-facing camera modules, and the rigid structure is disposed between the plurality of opposite-facing camera modules.

9. The camera accessory of claim 8, wherein the rigid structure is a heatsink configured to draw heat from the plurality of opposite-facing camera modules.

10. The camera accessory of claim 1, wherein the deformable structure has sufficient stiffness or hardness to absorb displacement and recoil the camera module to its position relative to the camera accessory.

11. The camera accessory of claim 1, wherein the deformable structure has a flat surface that contacts a flat surface of the camera barrel to support the position of the camera module.

12. The camera accessory of claim 11, wherein the camera barrel is at least partially sunken in the deformable structure.

13. The camera accessory of claim 11, wherein the flat surface of the camera barrel is not sunken in the deformable structure.

14. The camera accessory of claim 1, wherein the deformable structure has a flexible surface in contact with a flat, rigid surface of the camera barrel, which is partially sunken into the deformable structure.

15. The camera accessory of claim 1, wherein the deformable structure is configured to cause the camera module to recoil when a force is applied on the optical element.

16. A camera accessory mountable on a smartphone, the camera accessory comprising:

a plurality of opposite-facing camera modules including respective optical lenses for capturing images of different view of a scene;

a plurality of camera barrels such that each camera barrel at least partially surrounds a respective camera module to position the camera module relative to the camera accessory;

a heatsink disposed between the plurality of opposite-facing camera modules; and

a plurality of deformable structures such that each deformable structure couples a respective camera barrel and the rigid structure to exert a force that maintains the position of the camera module by compensating for displacement of the camera module relative to the camera accessory.

17. The camera accessory of claim 16, wherein each deformable structure is removable from the camera accessory and replaceable.

18. The camera accessory of claim 16, wherein the plurality of deformable structures is joined to the plurality of opposite-facing camera modules without an adhesive substance by a snapping together assembly the contents of the camera accessory.

19. The camera accessory of claim 16, wherein each camera module has a field-of-view of at least 180 degrees such that a collective field of view of the plurality of opposite-facing camera modules is 360 degrees.

20. A camera accessory comprising:

a camera module including an optical element configured to capture an image of a scene; and

a deformable structure that at least partially surrounds the camera module and supports the position of the camera module and compensates for displacement of the camera module relative to the camera accessory.
