Continuous adjustable 3deeps filter spectacles for optimized 3deeps stereoscopic viewing and its control method and means
View Patent ↗Continuous Adjustable 3Deeps Filter Spectacles are provided with lenses with continuously changeable optical densities, so that viewing of 2D movies is optimized for visualization in natural 3D. Method and means are disclosed for the continuous Adjustable 3Deeps Filter Spectacles to perform two independent optimizations to achieve optimized 3Deep visual effects on 2D movies. First they compute the optical density setting of the lenses for optimal viewing of 2D movies as 3D. Then they continuously render the lenses of the spectacles to these optical densities optimized for characteristics of the electro-optical material from which the lenses of the spectacles are fabricated. The invention works for both 3DTV and 3D Cinema theater viewing.
