A method and apparatus for generating an elemental image by an integral image technique are provided. The method includes normalizing coordinates of dots in a frustum formed in perspective projection by mapping the dots in the frustum into a cube; reversing a grade of depth of the cube viewed from a particular viewpoint; and generating a two-dimensional (2D) elemental image necessary for three-dimensional (3D) display from dots in the cube whose grade of depth is reversed.

A method and apparatus for managing content file information based on file paths are provided. The method includes creating a folder table comprising folder paths of content files and folder path identification information corresponding to the folder paths; creating a file table comprising file names of the content files and the folder path identification information corresponding to the content files; and managing the content file information based on information included in the folder table and the file table. The apparatus includes a storage unit which stores at least one content file, a folder table, and a file table; an information input unit which inputs information needed for managing content file information of the at least one content file; and a library module which manages the content file information stored in the storage unit.
