Abstract

The invention provides an imaging module disposed on a projection system. The imaging module comprises an extended lens device, which connects to the image outlet of the body of the projection system by a rotation mechanism. By rotating the rotation mechanism, the projection system may optionally project images through the extending lens device onto the screen in two perpendicular directions, of which the image ratio of the two images are reciprocal.

Claims

1. An imaging module for a projection system, the projection system comprising a body and an image outlet formed on the body, the projection system projecting an image from the image outlet of the body along a first direction, the imaging module comprising:

an extended lens device, rotatably connected to the image outlet, the extended lens device receiving the image from the imaging outlet and capable of being rotated from the first direction to one of a second direction and a third direction to selectively project the image onto a screen;

wherein any two of the first direction, the second direction and the third direction are substantially perpendicular to each other.

2. The imaging module as claimed in claim 1, wherein the imaging module further comprises a rotation mechanism disposed between the body and the extended lens device to enable the extended lens device to rotate around the first direction with respect to the body.

3. The imaging module as claimed in claim 2, wherein the extended lens device is adapted to be rotated around the first direction between a first position and a second position corresponding to the second direction and the third direction respectively.

4. The imaging module as claimed in claim 2, wherein the extended lens device is adapted to be rotated around the first direction by 360°

.

5. The imaging module as claimed in claim 1, wherein the extended lens device comprises a reflection component.

6. The imaging module as claimed in claim 5, wherein the reflection component is a reflection mirror or a prism.

7. The imaging module as claimed in claim 1, wherein the extended lens device comprises at least a lens.

8. The imaging module as claimed in claim 1, wherein the projection system further comprises a hinge structure, and the imaging module joints the body by the hinge structure such that the imaging module operates at an operating position or a closing position with respect to the body.

9. The imaging module as claimed in claim 1, wherein the extended lens device projects the image along a fourth direction, and the fourth direction is perpendicular to the first direction and either the second direction or the third direction.

10. The imaging module as claimed in claim 1, wherein the image has a first image ratio, a second image ratio and a third image ratio when being projected along the first direction, the second direction and the third direction respectively, and the first image ratio is equal to either the second image ratio or the third image ratio and reciprocal to another.

11. The imaging module as claimed in claim 10, wherein the first image ratio is 4:

3.

12. The imaging module as claimed in claim 10, wherein the first image ratio is 3:

4.

13. The imaging module as claimed in claim 10, wherein the first image ratio is 16:

9.

14. The imaging module as claimed in claim 10, wherein the first image ratio is 9:

16.
