IMAGE-PROJECTING AND IMAGE-CAPTURING SYSTEM AND METHOD

摘要

An image-projecting and image-capturing system primarily includes a projecting sub-system for projecting an image and a capturing sub-system for capturing an image. The capturing sub-system primarily comprises a zoom lens that consists of many lens groups moving along an optical axis. When capturing an image, the projecting sub-system is arranged at a location out of the optical axis; when projecting an image, the projecting sub-system is moved to aim the optical axis.
