Method and apparatus for reducing fatigue resulting from viewing three-dimensional image display, and method and apparatus for generating data stream of low visual fatigue three-dimensional image

摘要

Provided is a method of reducing fatigue resulting from viewing a three-dimensional (3D) image display. The method includes: obtaining low visual fatigue parameter information on a frame section including at least one frame of a received 3D image; obtaining disparity vector information on each frame of the 3D image; and determining a disparity minimum limit value and a disparity maximum limit value with respect to the 3D image.

1. A method of reconstructing a stereoscopic image from an image data stream in which stereoscopic image data is inserted, the method comprising:
parsing the stereoscopic image data stream in an International Standard Organization (ISO)-based media file format, the ISO-based media file format comprising a moov box, an mdat box, and a meta box; obtaining, from a first box in the meta box of the stereoscopic image data stream, low visual fatigue parameter information with respect to a frame section comprising at least one frame of a received stereoscopic image from the stereoscopic image data stream; extracting at least one of horizontal size information and vertical size information of the display device predetermined with respect to the stereoscopic image from the low visual fatigue parameter information; extracting viewing distance information predetermined with respect to the stereoscopic image from the low visual fatigue parameter information; and reconstructing the stereoscopic image using the stereoscopic image data extracted from the mdat box of the image data stream; wherein the low fatigue parameter is used for displaying the reconstructed stereoscopic image in a three dimensional display mode, and wherein the viewing distance information indicates a distance between the display device and a viewer.
