Abstract:
1. Three-dimensional image glasses comprising: a signal receiving section for receiving a right/left image-switching timing signal transmitted from a three-dimensional image display device which displays a right-eye image and a left-eye image alternately on time base; a right-eye liquid-crystal shutter and a left-eye liquid-crystal shutter for performing opening and closing operations for a right eye and a left eye according to the timing signal; a liquid-crystal shutter driving section for driving the right-eye liquid-crystal shutter and the left-eye liquid-crystal shutter; a learning section which learns a timing at which specific right-eye and left-eye liquid-crystal shutters adapted to a specific three-dimensional image display device are opened and closed according to a timing signal transmitted by the specific three-dimensional image display device; a storage section for storing an output pattern of the timing signal transmitted by the specific three-dimensional image display device, and an opening/closing timing corresponding to the output pattern and learned by the learning section; and a control section for selecting from the storage section an output pattern coincident with an output pattern of a timing signal received from the specific three-dimensional image display device via the signal receiving section, together with an opening/closing timing corresponding to this output pattern and moreover, by the selected opening/closing timing, controlling opening and closing of the right-eye liquid-crystal shutter and the left-eye liquid-crystal shutter in synchronization with the received timing signal, wherein the learning section has a light emitting element, a light emitting element driving circuit, a light receiving element, and a light receiving circuit for measuring a timing at which the specific right-eye and left-eye liquid-crystal shutters are opened and closed according to a transmission signal of the specific three-dimensional image display device, and the storage section stores the transmission signal of the specific three-dimensional image display device received by the signal receiving section and moreover stores an opening/closing timing of the specific right-eye and left-eye liquid-crystal shutters measured by the learning section.
