Abstract

Passive pop-out cameras for incorporation in foldable mobile electronic devices such as smartphones, lens systems for such cameras, and pop-out actuators, in some examples passive and in some examples based on shape memory alloys, for actuating the lens systems and other components in such cameras.

Claims (21)

1 . A lens system, comprising:

an image sensor having a sensor diagonal SD; and

a lens with a field of view FOV<80 degrees and having an f number f/#and N≥6 lens elements L 1 -L N arranged along a lens optical axis OA starting with L 1 from an object side toward an image side, the lens having a pop-out total track length TTL<15 mm and a back focal length BFL in a pop-out state, and a collapsed total track length c-TTL in a collapsed state, wherein the lens system is configured to switch from the pop-out state to the collapsed state and vice versa by collapsing the BFL to a collapsed c-BFL, wherein a ratio c-TTL/TTL≤0.9, and wherein f/#≤1.8.

2 . The lens system of claim 1 , wherein f/#≤1.7.

3 . The lens system of claim 1 , wherein f/#≤1.6.

4 . The lens system of claim 1 , wherein f/#≤1.5.

5 . The lens system of claim 1 , wherein c-TTL/TTL≤0.8.

6 . The lens system of claim 1 , wherein SD≥12 mm.

7 . The lens system of claim 1 , wherein TTL 13 mm≤TTL≤14 mm.

8 . The lens system of claim 1 , wherein BFL>0.15×TTL.

9 . The lens system of claim 1 , wherein BFL>0.2×TTL.

10 . The lens system of claim 1 , wherein BFL>0.3×TTL.

11 . The lens system of claim 1 , wherein c-TTL/SD<0.9.

12 . The lens system of claim 1 , wherein c-TTL/SD<0.8.

13 . The lens system of claim 1 , wherein c-TTL/SD<0.7.

14 . The lens system of claim 1 , wherein all N lens elements are made of plastic.

15 . The lens system of claim 1 , wherein N=6.

16 . The lens system of claim 15 , wherein a sequence of lens powers from L 1 to L 6 is minus-plus-minus-plus-minus-plus.

17 . The lens system of claim 1 , wherein the lens system is included in a pop-out camera.

18 . The lens system of claim 17 , wherein the pop-out camera is included in a mobile device.

19 . The lens system of claim 18 , wherein the mobile device is a smartphone.
