Claim 4:
5. A depth hyper-resolving method, comprising:
outputting, at an input data processing unit, a hierarchical input image and hierarchical input depth information by resolution conversion in accordance with a predetermined number of tiers for an input image and input depth information;
deriving, at a depth continuity estimation unit, hierarchical estimated depth continuity based on the hierarchical input image;
outputting, at a depth continuity mask deriving unit, based on the hierarchical input image and the hierarchical estimated depth continuity, a hierarchical depth continuity mask representing values of locations depending on whether a depth is continuous; and
deriving, at a cost function minimization unit, hyper-resolved depth information to minimize a cost function expressed by using the hierarchical input depth information, the hierarchical depth continuity mask, and the hyper-resolved depth information.
