Spatio-temporal confidence maps

An apparatus for generating a confidence map for a disparity map associated to a sequence of sets of two or more images, wherein the apparatus comprises:

• a motion determining unit configured to determine motion between at least two subsequent sets of two or more images;
• a region detector and separator configured to detect and separate static and dynamic regions in the images of the sets of two or more images based on the determined motion information;
• a determining unit configured to determine a disparity change between a disparity value determined for a static region of a current image and a motion compensated disparity value of a previous image;
• and
• a confidence map generator configured to take the result obtained by the determining unit into account for generating or refining a confidence map.
