Claim Text:
1. A projection apparatus, comprising: an image source for providing an image beam, wherein the image beam comprises a first sub image beam and at least one second sub image beam; a projection lens disposed on a transmission path of the image beam; a beam-splitting module for projecting the first sub image beam passing through the beam-splitting module onto a first imaging plane and projecting the second sub image beam reflected by the beam-splitting module onto at least one second imaging plane, wherein the projection lens is disposed on the transmission path of the image beam between the beam-splitting module and the image source; and at least one lens group disposed on at least one of a transmission path of the first sub image beam and a transmission path of the second sub image beam for adjusting a length of an optical path corresponding to the at least one of the transmission path of the first sub image beam and the transmission path of the second sub image beam projected by the projection lens, so as to adjust a magnification of an image projected onto at least one of the first imaging plane and the second imaging plane.
