PROJECTION SYSTEM HAVING A PHYSICAL MASK

摘要

A projection system includes a projection screen defining a shape and a projector configured to project an image onto the projection screen. The projector may project a static or dynamic image that has substantially the same shape as the projection screen or otherwise block portions of the projected image that are projected outside of the projection screen with the aid of a physical mask.
