First Claim
1. A shutter control system for glasses having right and left lenses that alternate between opaque and transmissive states during a given operating frame, the operating frames sequentially occurring in a periodic manner at a given synchronization rate, comprising:
- a receiver for receiving from an external source a shutter control command having imbedded therein shutter control information defining operating parameters of the right and left lenses, which shutter control information does not determine the periodic timing of the lenses; and
a control device for varying the operating parameters of the right and left lenses in accordance with said received shutter control information, such that the operating parameters of the right and left lenses in one time can be varied in the next and subsequent time in response to the received shutter control information in the next and subsequent time.

Abstract
A shutter control mechanism for 3-D glasses includes a control circuit (28) associated with the glasses, the glasses having 3-D lenses (20) and (22). The control circuitry (28) receives commands from a control transmitter (16) in the form of synchronization pulses and command signals. The command signals are operable to vary the operating parameters of the lenses (20) and (22). Specifically, the duty cycle of the left lens (22) and the right lens (20) are varied such that they can either be at a fifty percent duty cycle, greater than a fifty percent duty cycle or less than a fifty percent duty cycle, wherein the amount of time that each of the lenses is on can be controlled for a given frame length.
