Method and apparatus for adjusting parallax in three-dimensional video

An apparatus for adjusting parallax in a three-dimensional (3D) video, the apparatus comprising:

• a scene transition determining unit which determines whether a scene transition occurs between a previous frame and a current frame of an input 3D video sequence;
• a depth information analyzing unit which determines and compares first depth information of a previous scene which comprises a first plurality of frames including the previous frame and second depth information of a current scene which comprises a second plurality of frames including the current frame, if the scene transition unit determines that a scene transition occurs between the previous frame and the current frame;
• a depth information adjusting unit which, based on a result of the comparison of the first depth information and the second depth information by the depth information analyzing unit, adjusting parallax between the previous scene and the current scene by selectively adjusts depth information of at least one of the first plurality of frames of the previous scene and the second plurality of frames of the current scene if a difference between the first depth information and the second depth information exceeds a predetermined threshold value;
• and
• an output unit which outputs a 3D video sequence reconstructed based on a result of the determination of a scene transition and the result of the comparison of the first depth information and the second depth information.

A non-transitory computer readable recording medium having recorded thereon a computer program for executing a method of adjusting parallax of a three-dimensional (3D) video, the method comprising:

• receiving an input of a 3D video sequence;
• determining whether a scene transition occurs between a previous frame and a current frame of the 3D video sequence;
• if it is determined that a scene transition occurs between the previous frame and the current frame, determining and comparing first depth information of a previous scene which comprises a first plurality of frames including the previous frame and second depth information of a current scene which comprises a second plurality of frames including the current frame;
• and
• based on a result of the comparing the first depth information and the second depth information, adjusting parallax between the previous scene and the current scene by selectively adjusting depth information of at least one of the first plurality of frames of the previous scene and the second plurality of frames of the current scene if a difference between the first depth information and the second depth information exceeds a predetermined threshold value.
