Generation apparatus, system and method for generating virtual viewpoint image
To make it possible to obtain a natural virtual viewpoint image in which a structure or the like existing within an image capturing scene is represented three-dimensionally so as to be the same as a real one while suppressing a network load at the time of transmission of multi-viewpoint image data.
