An apparatus and a method for converting a two-dimensional image sequence into a three-dimensional image using a conversion of a motion disparity into a horizontal disparity and a post-processing method during the generation of a three-dimensional image are provided. The apparatus for converting a two-dimensional image sequence into a three-dimensional image according to the present invention includes a block motion measuring portion for measuring a motion vector for each block of a current image divided into blocks having a predetermined size using a previous image frame, a horizontal disparity generating portion for obtaining a horizontal disparity from the motion vector of each block according to the motion characteristic of the current image, an image generating portion for moving each block in a horizontal direction according to each horizontal disparity and generating a composite image corresponding to the current image, and an outputting portion for displaying a three-dimensional image formed of the current image and the composite image.

Disclosed is a method of transforming a stereoscopic image, including: extracting a depth map from a left-eye image and a right-eye image of the stereoscopic image as the left-eye image and the right-eye image are input; obtaining transformation information from the depth map; and transforming red, green, and blue (RGB) values of the stereoscopic image based on the transformation information. It is possible to provide a stereoscopic image having an improved three-dimensional effect, compared to an existing stereoscopic image.

A stereoscopic image generation apparatus generates a stereoscopic image using MPEG encoded data containing I, B and P pictures. A picture extractor extracts each picture data from the MPEG encoded data. A motion vector generator generates motion vectors individually corresponding to macroblocks in the picture and supplies the generated motion vectors to a motion vector field former. A picture storing unit stores pictures reproducted from the encoded picture data by the picture number K. A motion type determiner determines a motion type corresponding to a current picture using the motion vectors supplied from the motion vector field former. A stereoscopic image generator generates a mixed picture corresponding to the current picture using the previous pictures stored in the picture storing unit and the motion type determined in the motion type determiner and outputs the current picture and the mixed picture. A left/right picture determiner receives the current picture and the mixed picture output from the stereoscopic image generator and determines the received current picture into one of the left picture and the right picture forming a stereoscopic image and the mixed picture into the other thereof. Here, the motion type of the picture is determined as one of a still picture, a non-horizontal motion picture, a horizontal motion picture, and a fast motion picture, generates an optimal stereoscopic image adaptively to each determined motion type, determines the left/right picture of the stereoscopic image, thereby obtaining a natural and stable stereoscopic sense even in a variety of motion types of a picture.
