Abstract

The present invention relates to an apparatus for encoding / decoding digital stereoscopic images. In the present invention, one screen is set as a reference screen in two screens for implementing a stereoscopic image, and the reference screen is encoded by a compression algorithm of an international standard, and the other screen is encoded by transmitting only the difference value from the reference screen. In the decoding apparatus, the compressed data for the differential data between the reference screen and the reference screen transmitted in one bit stream type is divided into two channels to reconstruct the reference screen, the differential data is decoded and synthesized with the reconstructed reference screen Restores a screen other than the reference screen. As described above, the present invention has the effect of enabling a user to enjoy a stereoscopic image at a relatively low cost when applied to a next-generation video apparatus such as a digital video recorder (DVCR) or a digital video disk player (DVDP).
