Patent ID: 8044879

Claim:
A three-dimensional display system for providing stereo images to a user, said display system comprising: a pair of polarized glasses wearable by said user, said polarized glasses containing one lens for each of two eyes of the user, each said lens having a direction of polarization being orthogonal to the other said lens; a light source; a first and a second liquid crystal panel placed in stacked configuration between said light source and said user with said first liquid crystal panel being closer to said light source; a first polarizer being placed between said light source and said first liquid crystal panel and adapted to impart linear polarization of a first orientation to light directed toward said first liquid crystal panel; a second polarizer being placed between said first and second liquid crystal panels and having a polarization orientation orthogonal to said first polarizer; electronic processing means for processing a composite image from a stereopair, said stereopair comprising a left input image and a right input image, said processing means being further adapted to calculate an angle of polarization for each pixel of said second liquid crystal panel; and panel control means for receiving signals from said processing means and controlling operation of said panels in accord with said signals; wherein said composite image represents an average color intensity for each pixel of the left and right input images, and said angle of polarization φ for each pixel of the second liquid crystal panel can be calculated from the relationship tanφ=Square root of (L/R) where L is the intensity of a corresponding pixel for the left input image and R is the intensity of a corresponding pixel for the right input image, and wherein said panel control means causes said polarizers and said liquid crystal panels to polarize light from said source and rotate said polarized light such that a left image corresponding to said left input image is decoded by a left lens of said polarizer glasses and a right image corresponding to said right input image is decoded by a right lens of said polarizer glasses; and wherein said liquid crystal panels each comprise a plurality of pixels each having three sub-pixels corresponding to color components, and wherein said processing means utilizes an appropriate sub-pixel parameter γ to correct calculations relating to each color component according to the following formulas: B = ( L γ + R γ 2 ) 1 γ F = ( R γ L γ + R γ ) 1 γ wherein B is a color component intensity for a pixel of the first liquid crystal panel and F is a color component intensity for a pixel of the second liquid crystal panel and wherein γ is a different parameter for each color component/sub-pixel.
