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.
