Abstract
A free-viewpoint video generating method includes obtaining a multi-viewpoint video including N videos of N viewpoints (N being an integer greater than 1), and generating a free-viewpoint video of a virtual viewpoint based on the multi-viewpoint video such that the free-viewpoint video shows target areas and has a first resolution higher than each of resolutions of the N videos, the virtual viewpoint being different from the N viewpoints. For each target area, the generating includes: referring to a three-dimensional model generated based on the N videos to specify N reference areas which are shown by the N videos and which correspond to the each target area in the free-viewpoint video; and calculating components of pixels to represent the each target area in the free-viewpoint video, based on components of pixels to represent the N reference areas in the N videos.
