Method and device for generating a multi-viewpoint image are provided. The method of generating a multi-viewpoint image includes the steps of: acquiring at least one reference-viewpoint image; generating unit image information of a virtual-viewpoint image on the basis of unit image information of the reference-viewpoint image; multiplexing the unit image information of the reference-viewpoint image and the unit image information of the virtual-viewpoint image; and generating a multi-viewpoint image by performing an interpolation process on occluded areas between the multiplexed unit image information using the multiplexed unit image information. As a result, it is possible to avoid unnecessary processes of completing and rearranging individual viewpoint images in the course of generating a multi-viewpoint image.

Provided is a method and apparatus for encoding and decoding multi-view video data. The encoding method includes: decomposing each view image of the multi-view video into an overlapped region and a non-overlapped region, the overlapped region being overlapped with other view image and the non-overlapped region not being overlapped with other view image; generating a stitched image by combining the non-overlapped region of each view image and a middle view image; encoding the stitched image using a first encoding algorithm; and encoding the overlapped region of each view image, using a second encoding algorithm. Further, the decomposing step includes the steps of estimating disparity information for each view image, based on a predetermined view image; and decomposing each view image into said overlapped region and said non-overlapped region using the estimated disparity information.
