Stereoscopic 3-d viewing system with portable electro-optical viewing glasses and shutter-state control signal transmitter having multiple modes of operation for stereoscopic viewing of 3-d images displayed in different stereoscopic image formats

A stereoscopic 3-D image viewing system, comprising:

• a pair of stereoscopic 3-D shutter-type viewing glasses for support on the head of a human viewer, and viewing stereoscopic image pairs displayed on either a CRT-based computer device or a CRT-based television device using a prespecified time-multiplexing display technique;
• and
• a universal multi-sync signal detector including
• means for receiving signals from a first signal source, for driving said CRT-based computer monitor device,
• means for processing said signals from said first signal source so as to detect synchronization signals therein and generate control signals for controlling said pair of stereoscopic 3-D shutter-type viewing glasses so that a user wearing said pair of stereoscopic 3-D shutter-type viewing glasses can view stereoscopic image pairs displayed on said CRT-based computer monitor device according said prespecified time-multiplexing display technique, and
• means for receiving signals from a second signal source, for driving said CRT-based television device, and
• means for processing said from said second signal source so as to detect synchronization signals therein and generate control signals for controlling said pair of stereoscopic 3-D shutter-type viewing glasses so that said user wearing said pair of stereoscopic 3-D shutter-type viewing glasses can view stereoscopic image pairs displayed on said CRT-based television device according said prespecified time-multiplexing display technique.
