Patent ID: 7508485

Claim:
A video/motion picture displaying apparatus for viewing via 3D spectacles having a left lens and a right lens with transmissions of light individually controlled, including conventional analog or digital image data input and output ports, further comprising an internal 3D synchronizing unit comprising: a data capturing and converting means in the path between the input and output ports for capturing said image data and converting said image data to successive digital images for processing; a synchronizing means connected with said image capturing means for comparing lateral motions of an object in said successive digital images to identify synchronization events according to following rules: a left-to-right movement of said lateral motion corresponding to a setting in which the transmission of light in the right lens being in a partially blocked state and the transmission of light in the left lens being in a clear state; a right-to-left movement of said lateral motion corresponding to a setting in which said left lens being in the blocked state and said right lens being in the clear state; and no significant movement of said lateral motion corresponding to a setting in which said left lens and said right lens being all in the clear state; then translating said synchronization events into synchronizing signals with corresponding lens settings; and a transmitting unit connected with said synchronizing means to transmit said synchronizing signals as control codes trigging individual control of the transmission of light through said left lens and said right lens based on said lens settings corresponding to said synchronizing events; whereby two-dimensional motion pictures may be viewed as 3-D motion pictures by using the 3D spectacles.
