Abstract

An intermediate view synthesis apparatus for synthesizing an intermediate view image from a first image corresponding to a first view and a second image corresponding to a second view different from the first view, the first and second images including depth information, wherein the second image being is divided-up into a non-boundary portion, and a foreground/background boundary region, wherein the intermediate view synthesis apparatus is configured to project and merge the first image and the second image into the intermediate view to obtain an intermediate view image, with treating the foreground/background boundary region subordinated relative to the non-boundary portion. A multi-view data signal extraction apparatus for extracting a multiview data signal from a multi-view representation including a first image corresponding to a first view and a second image corresponding to a second view being different from the first view is also described, the first and second images including depth information.
