摘要： 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.
