3-D MOVING PICTURE VIEWING APPARATUS

摘要

A 3-D viewing apparatus for viewing moving pictures, the apparatus comprising a left-channel viewer and a right-channel viewer respectively for viewing by left-eye and right-eye of a user, and an electronically controlled shutter mechanism which is arranged to alternatively shut the left-channel viewer and the right-channel viewer such that a user only sees the left- and right- channels through the left- and right viewers respectively. The shutting frequency of the shutter mechanism is predetermined or preset by an electronic controller. The 3-D viewing glass has a shutting mechanism which is arranged to shut the left- and right-viewers at a predetermined, preset or pre-programmed means there is no need to extract electronic synchronization signals from the video source and this makes the 3-D viewing glass more economical and more convenient to use.
