Abstract: PURPOSE: A method for converting a two dimensional (2D) video into a three dimensional (3D) video and a device thereof are to covert a 2D video into a 3D video by using coloring information without flickering phenomena. CONSTITUTION: A difference video producing part (605) produces difference videos including information on differences in color values according to pixels of N^th frame using color differences. An accumulated video storage part (603) stores accumulated videos where information on differences in color values according to pixels is stored. Using the difference videos, a division-map video producing part (607) computes only pixels of which the difference in color values is above a predetermined level. The division-map video producing part produces depth map images and divided images of the N^th frame. A 3D video output part (609) converts a video of N^th frame into a 3D one and outputs it using the depth map images.
