System and method for simultaneously providing public and private images
Abstract:
System and methods for providing simultaneous public and private video, where a private viewer looking through an eye filter perceives the private video while a public viewer not looking through an eye filter perceives the public video. First a public image is generated and linearly polarized. The public image is then modulated to further encode a private image using an additional liquid crystal modulating layer. The modulated public image including the encoded private image is then received and filtered by various embodiments of passive or active eye filters comprising various combinations of spatial, temporal or spatial-temporal filters. The eye filters optionally include identifying means such that the system provides customized private images to selected eye filters. Means for providing private audio simultaneous with the private video are also shown. The system can be implemented as either a display or a projector and used in a destination-wide gaming system.
