Sony Corporation (Tokyo, JP) and Sony Pictures Entertainment Inc. (Culver City, CA) reveal a system for using quantum nanodots in motion pictures or video games in United States Patent 7,629,994 that is superior to current CGI (computer generated image) technology. According to inventor Bruce Dobrin, a quantum nanodot processing system includes at least one image capture camera configured to capture scenes including actors and/or objects in a visible band; and at least one marker capture camera configured to capture motions of the actors and/or objects applied with at least one quantum nanodot (QD) marker, wherein the at least one marker capture camera is tuned to capture narrowband IR signals emitted by the at least one QD marker.
In one implementation, the IR cameras are configured to capture the motion and surfaces of multiple actors and/or objects using QD markers attached to the actors/objects. In another implementation, the IR cameras are configured so that each IR camera detects different QD marker(s) tuned to a specific IR frequency. This implementation allows the IR cameras to discriminate between actors/objects within a capture volume. For example, three QD markers tuned to emit IR signals are attached to three different actors, and three IR marker capture cameras, each configured to capture only one QD marker, are used to discriminate between three actors.
The integrated data from image capture and marker capture cameras can be used in applications other than movies or video games, such as advertising, online or offline computer content (e.g., web advertising or computer help systems), any other animated computer graphics video applications, or other applications including machine vision applications. In another example, the QD markers can be tuned to emit signals other than IR signals such as signals in UV, microwave, or any other frequency range.
