USE OF A CCD CAMERA IN A PROJECTOR PLATFORM FOR SMART SCREEN CAPABILITY AND OTHER ENHANCEMENTS

摘要

An optical projection and capture system includes an image sensor integrated with an optical projection device. Additionally, the integrated device may be coupled with a laser pointer to deliver interactive presentations. The laser pointer may be pulsed to improve identifying and tracking a laser light spot on a projected image. These applications may be extended to rear projection systems for gaming and interactive graphics.
