Continuous adjustable 3deeps filter spectacles for optimized 3deeps stereoscopic viewing and its control method and means

A device for generating continuous optical density control signals for optimizing 3D effects on Pulfrich Filter Spectacles with two optical density continuously adjustable lenses, comprising:

• input means for setting a default optical density value for the two lenses in neutral state;
• input means for acquiring a motion vector value of a prominent image target in a sequence of frames in a 2D video;
• input means for acquiring a luminance value of each frame in said sequence;
• computing means for calculating an optical density adjustment value on each frame comprising the means for:
• computing a retinal delay based on the motion vector value for 3D effects;
• computing an adjusted luminance value to achieve said retinal delay based on the luminance value;
• computing an optical density value for a lens to achieve said adjusted luminance value;
• computing the optical density adjustment value based on the default optical density value;
• composing means for compiling optical density adjustment values on a sequence of frames in the 2D video as continuous optical density control values for the Pulfrich Filter Spectacles;
• and
• transforming means for transforming said continuous optical density control values into continuous optical density control signals.
