Abstract

Equipment and methods for the synchronization of stereoscopic projection displays are described. One projection system described includes at least one projector for projecting alternate left and right eye stereoscopic images for viewing with stereoscopic viewing eyewear, and further includes an image data storage and retrieval device capable of outputting an image data stream in a first image data format, a projector capable of producing displayed image frames for viewing and having at least one spatial light modulator and a signal processing unit capable of receiving the image data stream and converting the first format to a second image data format, wherein the second image data format is compatible with the at least one spatial light modulator, and a synchronizing device comprising a frame synchronizing signal detector, a time delay unit, and a synchronizing signal transmitter, wherein the frame synchronizing signal detector is capable of generating a synchronization signal for synchronizing the eyewear with the displayed image frames, the synchronizing signal transmitter is capable of transmitting the synchronization signal, and the time delay unit is capable of causing a time delay for transmission of the synchronizing signal based at least in part on either or both of the first image format and the second image data format.
