identifying a direction of said lateral motion;

configuring a synchronizing event according to following rules:

when said lateral motion of said object on the screen is:

from left to right, setting a synchronization signal to direct said left lens clear and said right lens partially blocked;

from right to left, setting a synchronization signal to direct said right lens clear and said left tens partially blocked;

non-existent, setting a synchronization signal to direct said left lens and said right lens both clear;

generating a synchronizing signal directing to the setting of lens based on said synchronization event; and

associating said synchronizing signal with said frames of said motion picture.

a data capturing means for capturing said video/motion pictures as image data/signal;

a converting means converting said image data to successive digital images;

a synchronizing means connected with said converting 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 light lens being in a 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;

and then translating said synchronization events into synchronizing signals with corresponding lens settings; and

an composing means for composing said synchronizing signals and said image data/signals of the video/motion picture into composite data/signals; or

an embedding means to incorporate said synchronizing signals into a suitable sound or video track of said video/motion picture.
