Patent ID: 8917954

Claim:
A method of converting a two-dimensional video to a three-dimensional video, the method comprising: comparing an image of an n th frame with an accumulated image until an n−1 th frame in the two-dimensional video to calculate a difference in a color value for each pixel; generating a difference image including information on a change in a color value for each pixel of the n th frame by using the difference in the color value; storing an accumulated image until the n th frame by accumulating the information on the change in the color value for each pixel until the n th frame; performing an operation only for a pixel in which a change in a color value is equal to or larger than a predetermined level in the n th frame by using the difference image to generate a division image and a depth map image of the n th frame; and converting the image of the n th frame to a three-dimensional image by using the depth map image.
