Stereoplexing for film and video applications
First Claim
1. A method for multiplexing stereoscopic image source data, the method comprising:
- receiving the stereoscopic image source data comprising a left image and a right image;
forming a multiplexed image frame configured to have a precursor format, wherein the multiplexed image frame defines a first image aspect ratio;
providing the multiplexed image frame;
wherein the precursor format of the multiplexed image frame comprises the right image in a first portion of the multiplexed image frame and the left image in a second portion of the multiplexed image frame; and
wherein one of the right image or the left image is divided into a plurality of blocks, the plurality of blocks being re-arranged from a first block arrangement to a second block arrangement different from the first block arrangement, and the other one of the right image or left image is downscaled to a downscaled right image or left image having a second image aspect ratio that is substantially the same as the first image aspect ratio.

Abstract
A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.

18. A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames, the method comprising:
-
receiving stereoscopic image source data comprising left images and right images; and providing a series of single frames divided into portions, each single frame define a first image aspect ratio and containing one right image in a first portion and one left image in a second portion; wherein the providing comprises, in at least one single frame, dividing one of the respective right image or the respective left image into a plurality of blocks and re-arranging the plurality of blocks from a first block arrangement to a second block arrangement different from the first block arrangement; and wherein the other one of the respective right image or the respective left image is downscaled to a second image aspect ratio that is substantially the same as the first image aspect. - View Dependent Claims (19)

20. A method for multiplexing stereoscopic image source data, the method comprising:
-
receiving the stereoscopic image source data comprising a left image and a right image; forming a multiplexed image frame configured to have a precursor format, wherein the multiplexed image frame comprises a horizontal pixel count and a vertical pixel count that define a first aspect ratio; providing the multiplexed image frame; wherein the precursor format of the multiplexed image frame comprises the right image in a first portion of the multiplexed image frame and the left image in a second portion of the multiplexed image frame; and wherein one of the right image or the left image is divided into a plurality of blocks, the plurality of blocks being re-arranged from a first block arrangement to a second block arrangement different from the first block arrangement, wherein the re-arrangement includes rotation of the blocks, and the other one of the right image or left image comprises a horizontal pixel count and a vertical pixel count that define a second aspect ratio, the first and second aspect ratios being substantially the same.
