Three-dimensional video creating device and three-dimensional video creating method
First Claim
1. A three-dimensional video creating device which creates a three-dimensional (3D) video from a two-dimensional (2D) video, said three-dimensional video creating device comprising:
- a receiving unit configured to receive a 2D video;
a selection unit configured to select, from among frames constituting the 2D video, frames each of which has a common area whose proportion to the frame is greater than or equal to a predetermined value, as candidate three-dimensional partner frames that are candidate frames each constituting a three-dimensional image together with a target frame included in the frames constituting the 2D video, each of the common areas being an area of an image common to the target frame;
a determination unit configured to determine, from among the candidate three-dimensional partner frames, a three-dimensional partner frame that is a frame which, together with the target frame, constitutes a three-dimensional image, based on predetermined criteria;
a three-dimensional pair creation unit configured to create a three-dimensional pair constituting the three-dimensional image corresponding to the target frame, using the target frame and the three-dimensional partner frame; and
a conversion unit configured to generate, from the target frame and the candidate three-dimensional partner frames selected by said selection unit, a transformation matrix for warping the candidate three-dimensional partner frames, and convert the three-dimensional pair by applying the generated transformation matrix to the three-dimensional pair.

Abstract
A three-dimensional video creating device (100) includes: a selection unit (123) which selects, from among frames constituting the 2D video, frames each of which has a common area whose proportion to the frame is greater than or equal to a predetermined value, as candidate three-dimensional partner frames that are candidate frames each constituting a three-dimensional image together with a target frame included in the frames constituting the 2D video; a determination unit (124) which determines, from among the candidate three-dimensional partner frames, a three-dimensional partner frame, based on the first criteria; and a three-dimensional pair creation unit (125) which creates a three-dimensional pair constituting the three-dimensional image corresponding to the target frame, using the target frame and the three-dimensional partner frame.

16. A three-dimensional video creating method for creating a three-dimensional (3D) video from a two-dimensional (2D) video, said three-dimensional video creating method comprising:
-
receiving a 2D video; selecting, from among frames constituting the 2D video, frames each of which has a common area whose proportion to the frame is greater than or equal to a predetermined value, as candidate three-dimensional partner frames that are candidate frames each constituting a three-dimensional image together with a target frame included in the frames constituting the 2D video, each of the common areas being an area of an image common to the target frame; determining, from among the candidate three-dimensional partner frames, a three-dimensional partner frame that is a frame which, together with the target frame, constitutes a three-dimensional image, based on predetermined criteria; creating a three-dimensional pair constituting the three-dimensional image corresponding to the target frame, using the target frame and the three-dimensional partner frame; and generating, from the target frame and the candidate three-dimensional partner frames selected in said selecting, a transformation matrix for warping the candidate three-dimensional partner frames, and converting the three-dimensional pair by applying the generated transformation matrix to the three-dimensional pair.
