Method and apparatus for converting 2d content into 3d content

An apparatus for converting video contents, which converts two-dimensional (2D) contents into three-dimensional (3D) contents, the apparatus comprising:

• a user input unit which receives a user command;
• a display unit;
• and
• a converter which displays a frame including an object which will be extracted from among plural frames contained in the 2D contents, designates a boundary region of an object to be extracted on the displayed frame in accordance with a user command through a user interface (UI) for collectively designating a region, generates a trimap comprising inner and outer regions of the object to be extracted, based on the designated boundary region, and extracts the object based on the generated trimap.

A method of converting video contents, which converts two-dimensional (2D) contents into three-dimensional (3D) contents through a content converting apparatus, the method comprising:

• displaying a 2D frame including an object which will be extracted;
• designating a boundary region of the object to be extracted on the displayed frame;
• generating a trimap based on the designated boundary region, the trimap comprising inner and outer regions of the object to be extracted;
• and
• extracting the object based on the generated trimap.
