Abstract:
1. A three-dimensional (3D) video processing apparatus that processes a video signal which includes video data indicating a 3D video and control information on the video data, said 3D video processing apparatus comprising: an extracting unit configured to extract, from the control information, an offset value that is assigned to each of pictures included in the video data and indicates an amount by which at least part of the picture is shifted to adjust a depth-wise display position of the part; an offset value complementing unit configured to complement the offset value of a first picture using the offset value extracted by said extracting unit, by assigning, to the first picture, the offset value which is equal to or greater than a first offset value and equal to or smaller than a second offset value, the first offset value representing a smaller one of the offset value assigned to a second picture temporally preceding the first picture and the offset value assigned to a third picture temporally succeeding the first picture, and the second offset value representing a larger one of the offset value assigned to the second picture and the offset value assigned to the third picture; an offset control unit configured to adjust the depth-wise display position of at least part of the first picture by shifting the part by an amount corresponding to the offset value complemented by said offset value complementing unit; and an error determining unit configured to determine whether or not the offset value assigned to each of the pictures included in the video data is appropriate; wherein the first picture is a picture which has the offset value determined as not appropriate by said error determining unit, the second picture is a picture which has the offset value determined as appropriate by said error determining unit and immediately precedes the first picture, the third picture is a picture which has the offset value determined as appropriate by said error determining unit and immediately succeeds the first picture, and wherein said error determining unit is configured to determine that the offset value of a current picture is not appropriate, when at least one of the following differences is equal to or greater than a predetermined threshold: a difference between the offset value of the current picture and the offset value of a picture immediately preceding the current picture; and a difference between the offset value of the current picture and the offset value of a picture immediately succeeding the current picture.
