Abstract

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.

Claims

1. An optical-density-continuous-adjustable Pulfrich Filter Spectacles for viewing a 2D video with 3D effects, comprising:

a) two lenses each having optical density continuously adjustable;

b) a continuous optical density signal receiving unit for receiving optical density continuous control values based on a motion vector of a prominent image target in a sequence of frames in the 2D video; and

c) a control unit transforming said continuous optical density signals into continuous control mechanism to set corresponding optical density for each lens when the sequence of frames is displayed.

2. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 1, further comprising a frame, on which the two lenses, the signal receiving unit and the control unit are mounted.

3. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 1, further comprising an IC chip with a circuitry adjusting optical density balance based on ambient luminance.

4. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 1, wherein the signal receiving unit is a wireless receiver.

5. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 2, further comprising a power source mounted on the frame.

6. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 2, further comprising a photosensor mounted on the frame.

7. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 1, wherein the lenses are made of a material having continuous optical density adjustable capacity, which is selected from a group consisting of:

electrochromatic material, LCD, suspended particle device, and polarizable optical material.

8. An optical-density-continuous-adjustable Pulfrich Filter Spectacles of claim 1, wherein the material is electrochromatic material and the control mechanism is based on electric voltages.
