Abstract

Claims (24)

1. A folded camera module, comprising:

a movable lens barrel comprising a plurality of lens elements having a lens optical axis and positioned in an optical path between an optical path folding element (OPFE) and an image sensor, wherein the OPFE folds light from a first direction to a second direction, the second direction being substantially along the lens optical axis, and wherein the lens barrel has a lens barrel height along the first direction and a lens barrel surface;

an actuator for controlled lens movement, the actuator including a shield having a shield thickness, wherein the shield has a shield opening substantially the same length as the lens barrel such that the shield partially surround the lens barrel; and

a lid having a lid thickness and covering the shield opening,

wherein the folded camera has a camera height measured along the first direction, and wherein the camera height is substantially equal to a sum of the lens barrel height, the lid thickness, the shield thickness, a size of a first air gap between a first point on the lens barrel surface facing the lid and the lid, and a size of a second air gap between a second point on the lens barrel surface diametrically opposed to the first point and facing the shield and the shield.

2. The folded camera module of claim 1 , wherein the actuator has an opening positioned and dimensioned to enable installation of the lens barrel into the shield from an insertion direction substantially parallel to the first direction.

3. The folded camera module of claim 1 , further comprising a lens carrier for holding the lens barrel, wherein the lens carrier has a V-groove structure for mechanically positioning the lens barrel in a correct position during installation.

4. The folded camera module of claim 1 , wherein the actuator includes a base, and wherein at least parts of the base are surrounded by the shield.

5. The folded camera module of claim 1 , wherein the lid is fixedly attached to the shield.

6. The folded camera module of claim 1 , wherein the camera height does not exceed the lens barrel height by more than 800 μm.

7. The folded camera module of claim 1 , wherein the camera height does not exceed the lens barrel height by more than 700 μm.

8. The folded camera module of claim 1 , wherein the camera height does not exceed the lens barrel height by more than 600 μm.

9. The folded camera module of claim 1 , wherein each of the first and second air gaps is in the range of 10-50 μm.

10. The folded camera module of claim 1 , wherein each of the first and second air gaps is in the range of 10-100 μm.

11. The folded camera module of claim 1 , wherein each of the first and second air gaps in the range of 10-150 μm.

12. The folded camera module of claim 1 , wherein the movable lens barrel is movable for focusing.

13. The folded camera module of claim 1 , wherein the movable lens barrel is movable for optical image stabilization.

14. The folded camera module of claim 1 , wherein the image sensor is wire-bonded to a printed circuit board with wire bonds located on sides of the image sensor that are substantially parallel to the first direction.

15. The folded camera module of claim 1 , wherein the OPFE is a prism.

16. The folded camera module of claim 1 , wherein the OPFE is a mirror.

17. The folded camera module of claim 1 , included together with a non-folded camera in a dual-camera.

18. The folded camera module of claim 1 , wherein the folded camera module is included in a mobile device.

19. The folded camera module of claim 18 , wherein the mobile device is a smartphone.

20. The folded camera module of claim 19 , wherein the mobile device is a tablet.
