Continuous adjustable 3Deeps filter spectacles for optimized 3Deeps stereoscopic viewing and its control method and means
View Patent ↗Continuous Adjustable Pulfrich 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 Pulfrich Filter Spectacles to perform two independent optimizations to achieve optimized 3Deeps 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.
1. A method for generating modified video, comprising:
(1) acquiring a source video comprised of a sequence of 2D frames;
(2) determining a value for an inter-ocular distance of the viewer and factors for a display resolution and a video frame speed;
(3) obtaining an image frame from the source video that includes:
(a) two or more motion vectors that describe motion in the image frame where each of the motion vectors is associated with a region of the image frame; and
(b) one or more values that describe the luminance in the image frame;
(4) calculating a single parameter for each of the following:
(a) a lateral speed of the image frame, using the two or more motion vectors;
(b) a direction of motion of the image frame, using the two or more motion vectors; and
(c) a luminance of the image frame, using the one or more luminance values;
(5) generating a deformation value by applying an algorithm that uses the inter-ocular distance, both of the factors, and at least two of the parameters;
(6) applying the deformation value to the image frame to produce a modified image frame; and
(7) displaying the modified image frame to a viewer;
wherein the direction of motion and velocity of motion parameters in the calculation step are calculated only from the motion vectors input along with the image frame and the luminance parameter is calculated only from the one or more luminance values input along with the image frame.
2. A method according to claim 1 , wherein in the modified video in the displaying step is presented to a viewer through spectacles.
