Process and system for encoding and playback of stereoscopic video sequences
First Claim
1. A method for displaying images, comprising:
- in a conventional two-dimensional (2D) viewing mode;
driving a 2D image of a plurality of 2D images to a head mountable display; and
in a stereoscopic three-dimensional (3D) viewing mode;
driving to the head mountable display a left image of a plurality of left images for left eye viewing, wherein at least a portion of the plurality of left images are generated using time interpolation to increase a frame rate of the display, and a right image of a plurality of right images for right eye viewing, the left image and the right image being time-synchronized with parallax for perception of depth in the stereoscopic 3D viewing mode, wherein the driving comprises simultaneous dual presentation of the left image and the right image.

Abstract
A method for decoding a compressed image stream, the image stream having a plurality of frames, each frame consisting of a merged image including pixels from a left image and pixels from a right image. The method involves the steps of receiving each merged image; changing a clock domain from the original input signal to an internal domain; for each merged image, placing at least two adjacent pixels into an input buffer and interpolating an intermediate pixel, for forming a reconstructed left frame and a reconstructed right frame according to provenance of the adjacent pixels; and reconstructing a stereoscopic image stream from the left and right image frames. The invention also teaches a system for decoding a compressed image stream.
