1. A method of reconstructing a stereoscopic image from an image data stream in which stereoscopic image data is inserted, the method comprising: parising the stereoscopic image data stream and obtaining 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 image data stream; wherein the low fatigue parameter is used for displaying the reconstructed stereoscopic image in a three dimensional display mode.
