1. A method of reconstructing stereoscopic images, the method comprising: determining first blocks at first positions and second blocks at second positions, which are different from the first blocks at the first positions, from among blocks obtained by dividing a combined image; generating a first preliminary image including the first blocks at the first positions and a second preliminary image including the second blocks at the second positions; and reconstructing a base view image and an additional view image based on the first preliminary image and the second preliminary image, respectively.
