Method and apparatus for generating stereoscopic image from two-dimensional image by using mesh map

An apparatus for generating a stereoscopic image from a two-dimensional (2D) image by using a mesh map, the apparatus comprising:

• a reception unit for receiving the 2D image including a still image or a moving picture from an external device and receiving mesh shapes and depth information of a mesh map, which are edited by a user;
• a screen reference unit for generating a stereoscopic image by applying the mesh shapes and the depth information of the mesh map that is being currently edited, to the 2D image and displaying the stereoscopic image and the mesh map by overlapping the stereoscopic image and the mesh map;
• an information management unit for managing the mesh shapes and the depth information of the mesh map that is edited by the user in accordance with shapes of a displayed image;
• a calculation unit for calculating relative depth information of the 2D image by calculating an average relative depth value for each pixel of the 2D image by calculating:
• an x-coordinate value and a y-coordinate value of each corner of the mesh map;
• a distance rate from each pixel to each corner of the mesh map;
• a z-coordinate depth value for each corner of the mesh map based on the mesh map edited by the user;
• product values of inverse-proportionally multiplying the z-coordinate depth value of each corner of the mesh map by the distance rate of each corner of the mesh map from the pixel;
• and
• an average of the product values;
• and
• a stereoscopic image generation unit for generating a stereoscopic image file by using the calculated relative depth information of the 2D image.
