  • Patent number: 7720368
    Abstract: The present invention provides a system, method and apparatus for enhancing a projected image to reduce the optical depth of field, and create a more desirable film-like image. The present invention provides a multi-function imaging element for enhancing a projected image that includes a focusing screen that minimizes light hot spots in an image projected on the focusing screen and filters ultraviolet rays. The focusing screen can be static, moving, oscillating or rotating. The ultraviolet rays are filtered using a coating on the focusing screen, or by a separate filter made of glass, plastic or film. Note that the multi-function imaging element can be integrated into an adapter, a camera, a video camera, a projector, a television, a monitor, or other image capture or display device.
