Provided are a method, system, and an apparatus for reconstructing intermediate video using symmetric disparity estimation. A virtual video area is set in an intermediate-view of a left image and a right image, and the virtual video is divided into predetermined block units. A left disparity vector and a right disparity vector are estimated by moving blocks of the left image and right image on a pixel-by-pixel basis symmetrically with respect to reference coordinates of an arbitrary block among the divided block units, and intermediate-view video with pixel values of a left image and a right image are formed from the estimated left disparity vector and right disparity vector.
