Provided is a method of decoding a stereoscopic image data stream. In the method, a plurality of monoscopic image data regions are determined from among image data regions of a stereoscopic image data stream; a composition time stamp (CTS) of each of the monoscopic image data regions is extracted; and, if there are colliding image data regions having the same CTS from among the monoscopic image data regions, monoscopic image data is extracted from a monoscopic image data region of a main stream of the colliding image data regions.

A method and apparatus for using header information of stereoscopic image data is provided. The method includes using three-dimensional reproduction period information related to three-dimensionally reproduced stereoscopic image data of image data recorded in a payload region of the stereoscopic image bitstream, in a header region of the stereoscopic image bitstream; recording camera information related to cameras used for obtaining a stereoscopic image, in the header region; recording parallax information between base and additional images of the stereoscopic image in the header region; and recording the image data in the payload region of the stereoscopic image bitstream.
摘要:
A method and apparatus for reproducing a stereoscopic image are provided. The method includes generating information about parallax between a left-eye image and a right-eye image of objects included in the stereoscopic image based on a stereo camera parameter of the stereoscopic image, controlling the depth of the objects in the stereoscopic image based on the generated information, and reproducing the stereoscopic image based on the controlled depth. Accordingly, the stereoscopic image can be reproduced while minimizing the eye fatigue of a viewer.

Provided are a methods and apparatuses for generating a stereoscopic image format and reconstructing stereoscopic images from the stereoscopic image format. The method of generating a stereoscopic image format for compression or transmission of stereoscopic images includes receiving a base view image and an additional view image, determining block pixel information for the stereoscopic image format for each block position using first block pixel information of the base view image and second block pixel information of the additional view image based on blocks obtained by dividing the base view image and the additional view image, and disposing the determined block pixel information in each block position, thereby generating a combined image including pixel information of the base view image and pixel information of the additional view image.
