Abstract

An imaging device includes a housing, a carrier arranged within the housing, an optical assembly supported by the carrier within the housing, and a plurality of non-optical components arranged within the housing. The carrier includes one or more frame components that are configured to rotate relative to the housing about one or more axes of rotation. The optical assembly includes one or more lenses and an image sensor. The optical assembly is movable relative to the housing via the carrier about the one or more axes of rotation. At least one of the non-optical components is (1) operably coupled to the optical assembly and (2) not supported by the carrier.

First claim

What is claimed is:

1. An imaging device comprising:
a housing;
a carrier arranged within the housing, wherein the carrier comprises one or more frame components that are configured to rotate relative to the housing about one or more axes of rotation;
an optical assembly supported by the carrier within the housing, wherein the optical assembly comprises one or more lenses and an image sensor, and wherein the optical assembly is movable relative to the housing via the carrier about the one or more axes of rotation; and
a plurality of non-optical components arranged within the housing, wherein:
one or more of the plurality of non-optical components are attached to an inner surface of the housing or mounted on a printed circuit board (PCB); and
the plurality of non-optical components comprises a battery attached to the inner surface of the housing and configured to supply power to the optical assembly and the one or more of the plurality of non-optical components.

2. The imaging device of claim 1 , wherein the one or more lenses are supported by a lens barrel.

3. The imaging device of claim 2 , wherein the one or more lenses are partially enclosed in the lens barrel.

4. The imaging device of claim 2 , wherein the one or more lenses are fully enclosed within the lens barrel.

5. The imaging device of claim 2 , wherein the lens barrel is operably coupled to at least one frame component of the carrier.

6. The imaging device of claim 1 , wherein the image sensor is provided on the PCB supported by a substrate holder.

7. The imaging device of claim 6 , wherein a lens barrel supporting the one or more lenses is operably coupled to the substrate holder, such that the one or more lenses in the lens barrel and the PCB are movable relative to each other.

8. The imaging device of claim 7 , wherein the lens barrel is movable along an optical axis of the optical assembly to adjust a distance between the one or more lenses and the image sensor.

9. The imaging device of claim 7 , wherein the PCB is movable along an optical axis of the optical assembly to adjust a distance between the image sensor and the one or more lenses.

10. The imaging device of claim 7 , wherein the PCB and the lens barrel are movable along an optical axis of the optical assembly to adjust a distance between the image sensor and the one or more lenses.

11. The imaging device of claim 7 , wherein at least one of the lens barrel or the substrate holder is rigidly attached to at least one of the one or more frame components of the carrier.

12. The imaging device of claim 7 , wherein at least one of the lens barrel or the substrate holder is movably attached to at least one of the one or more frame components of the carrier.

13. The imaging device of claim 6 , wherein the substrate holder is integrally formed with a lens barrel supporting the one or more lenses.

14. The imaging device of claim 6 , wherein the substrate holder is operably coupled to at least one frame component of the carrier.

15. The imaging device of claim 1 , wherein the optical assembly is rotatable about one or more axes of rotation relative to a number of the plurality of the non-optical components within the camera housing.

16. The imaging device of claim 1 , wherein each frame component of the one or more frame components is actuated to rotate around an axis of rotation by a motor that is operably coupled to the frame component.

17. The imaging device of claim 1 , wherein at least one portion of the housing is transparent to allow a line of sight from the optical assembly to an environment external to the housing during rotation of the optical assembly.

18. The imaging device of claim 17 , wherein the at least one portion of the housing comprises a removable transparent cover.

19. The imaging device of claim 1 , wherein a rotational movement of the carrier is measured using one or more sensors.

20. The imaging device of claim 19 , further comprising at least one inertial sensor attached to the carrier or the optical assembly.
