Abstract

An image capture device including a housing, a first lens unit, a second lens unit, an image sensing element, and a beam spliter is provided. The housing includes a body, a first lens barrel, and a second lens barrel. The first lens unit is disposed within the first lens barrel and includes a first switchable light valve. The second lens unit is disposed within the second lens barrel and includes a second switchable light valve. The image sensing element faces to the first lens unit. The beam spliter is configured in front of the image sensing element so that the image sensing element is able to receive a first image light passing through the first lens unit and a second image light passing through the second lens unit. The first switchable light valve and the second switchable light valve present a transparent state at different timings.

Claims

1. An image capture device comprising

a housing comprising a body, a first lens barrel, and a second lens barrel, wherein the first lens barrel and the second lens barrel are inter-connected with the body;

a first lens unit disposed within the first lens barrel of the housing, wherein the first lens unit comprises a first switchable light valve so as to allow a first image light to pass through the first lens unit;

a second lens unit disposed within the second lens barrel of the housing, wherein the second lens unit comprises a second switchable light valve so as to allow a second image light to pass through the second lens unit;

an image sensing element disposed within the body; and

a beam splitter disposed on at least one of a light path of the first image light and a light path of the second image light so as to allow the image sensing element to receive the first image light and the second image light, wherein the first switchable light valve and the second switchable light valve present a transparent state at different timings.

2. The image capture device of claim 1, wherein the beam splitter is disposed between the first lens unit and the image sensing element.

3. The image capture device of claim 1, wherein the image sensing element faces towards the first lens unit.

4. The image capture device of claim 1, wherein the first lens barrel and the second lens barrel comprise different extended directions so as to allow the first lens unit and the second lens unit to face towards different directions.

5. The image capture device of claim 1, wherein the first lens unit further comprises at least one lens, and the at least one lens is disposed on a side of the first switchable light valve.

6. The image capture device of claim 1, wherein the second lens unit further comprises at least one lens, and wherein the at least one lens is disposed on a side of the second switchable light valve.

7. The image capture device of claim 1, wherein each of the first switchable light valve and the second switchable light valve individually comprises a liquid crystal unit and two polarizers disposed on two opposite sides of the liquid crystal unit.

8. The image capture device of claim 1, wherein the first lens barrel and the second lens barrel mutually overlap in a direction, the housing further comprises a rotating mechanism, and the rotating mechanism is disposed between the first lens barrel and the second lens barrel so as to allow at least one of the first lens barrel and the seconds barrel to suitably rotate on a plane perpendicular to the direction.

9. The image capture device of claim 8, wherein extended directions of the first lens barrel and the second lens barrel are different so as to allow the first lens unit and the second lens unit to face towards different directions.

10. The image capture device of claim 1 further comprising a light path adjusting element disposed on a side of the second lens unit so as to adjust a path of the second image light and allow the second image light to pass towards the beam splitter.

11. The image capture device of claim 10, wherein the light path adjusting element is a reflector or a prism.

12. The image capture device of claim 1 further comprising a third lens unit, wherein the housing further comprises a third lens barrel, the third lens unit is disposed within the third lens barrel, and the third lens unit comprises a third switchable light valve so as to allow a third image light to pass through the third lens unit, and wherein the first switchable light valve, the second switchable light valve, and the third switchable light valve present a transparent state at different timings so as to allow the image sensing element to receive the first image light, the second image light, and the third image light at different timings.

13. The image capture device of claim 12, wherein the third lens unit further comprises at least one lens disposed on a side of the third switchable light valve.

14. The image capture device of claim 12, wherein the third switchable light valve comprises a liquid crystal unit and two polarizers disposed on two opposite sides of the liquid crystal unit.

15. The image capture device of claim 12, wherein each of the first lens barrel, the second lens barrel, and the third lens barrel individually extends to a different direction so as to allow the first lens unit, the second lens unit, and the third lens unit to face towards different directions.

16. The image capture device of claim 12, wherein the second lens barrel and the third lens barrel are substantially disposed on two opposite sides of the first lens barrel.

17. The image capture device of claim 12, wherein the second lens barrel and the third lens barrel are substantially disposed on two adjacent sides of the first lens barrel.

18. The image capture device of claim 17, wherein the housing further comprises a rotating mechanism, and wherein the rotating mechanism is disposed between the first lens barrel and the second lens barrel so as to allow the second lens barrel to suitably rotate on a side of the first lens barrel.
