Process and system for encoding and playback of stereoscopic video sequences
First Claim
1. A system for processing a stereoscopic image stream having a merged frame format, comprising:
- a spatial interpolation module configured to spatially interpolate each merged frame of said stereoscopic image stream into reconstructed frame data;
a buffer configured to store said reconstructed frame data;
a memory controller configured to read out said reconstructed frame data from said buffer;
a temporal interpolation module configured to generate an output stream of frames using temporal interpolation of said reconstructed frame data, wherein said temporal interpolation is in accordance with a selected one of a plurality of stereoscopic 3D display modes; and
an output configured to output said output stream of frames.

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.

5. A system for decoding stereoscopic video, said stereoscopic video formed by topologically decimating a first image sequence and a second image sequences, each having a first display rate, to form adjacent portions of a third image sequence having a second display rate less than twice said first display rate, and encoding said third image sequence for transport through a data transport medium, said system comprising:
a processor configured to; decode said third image sequence from the encoded third image sequence received from said data transport medium; topologically interpolate each of said adjacent portions of said third image sequence to form a first rebuilt image sequence and a second rebuilt image sequence respectively; for each of said first rebuilt image sequence and said second rebuilt image sequence, apply temporal interpolation to at least two successive images in said sequence to form at least one additional image; for each of said first rebuilt image sequence and said second rebuilt image sequence, modify said sequence by inserting said at least one additional image into said sequence to increase the display rate of said sequence; and in a page flipping mode, an output image sequence comprised of successively alternating images from each of said first rebuilt image and second rebuilt image sequence of increased display rate. - View Dependent Claims (6, 7, 8, 9, 10)
