Abstract
A three-dimensional video processing apparatus includes: a video obtaining unit which obtains a 3D video for three-dimensional viewing; a position obtaining unit which obtains a position of a first area which is an area included in a part of the 3D video; a disparity obtaining unit which obtains disparity amounts of the 3D video; a determination unit which determines a size of an enlargement area; and an area selection unit which selects, as the enlargement area, at least one second area that has disparity amounts within a predetermined range, includes the first area, and has a size determined by the determination unit.
Claims8
A three-dimensional video processing apparatus that performs processing for enlarging a part of 3D video for three-dimensional viewing displayed on a display screen by a predetermined magnification on the display screen, the apparatus comprising:
- a video obtaining unit configured to obtain the 3D video;
- a position obtaining unit configured to obtain a position of a first area which is an area included in the part of the 3D video;
- a disparity obtaining unit configured to obtain disparity amounts of the 3D video per processing unit obtained by dividing the 3D video by a predetermined number of pixels;
- a determination unit configured to determine a size, on the display screen, of an enlargement area based on a size of the display screen and the predetermined magnification, the enlargement area being included in the part of the 3D video;
- an area selection unit configured to select, as the enlargement area, at least one of a plurality of second areas that includes processing units each having a disparity amount within a predetermined range, the second areas being included in the part of the 3D video, and each including the first area and having a size determined by the determination unit;
- and
- an evaluation value calculation unit configured to calculate an evaluation value of each of the processing units,
- wherein the evaluation value is a sum of a first evaluation value and a second evaluation value, the first evaluation value decreasing as an absolute value of the disparity amount of the processing unit is less, and the second evaluation value decreasing as a position of the processing unit on the display screen is closer to the position of the first area, and
- the area selection unit is configured to select, as the enlargement area, at least one of the second areas that includes processing units having a smallest sum of the evaluation values.
A three-dimensional video processing method for performing processing for enlarging a part of 3D video for three-dimensional viewing displayed on a display screen by a predetermined magnification on the display screen, the method comprising:
- obtaining the 3D video;
- obtaining a position of a first area which is an area included in the part of the 3D video;
- obtaining disparity amounts of the 3D video per processing unit obtained by dividing the 3D video by a predetermined number of pixels;
- determining a size, on the display screen, of an enlargement area based on a size of the display screen and the predetermined magnification, the enlargement area being included in the part of the 3D video;
- selecting, as the enlargement area, at least one of a plurality of second areas that includes processing units each having a disparity amount within a predetermined range, the second areas being included in the part of the 3D video, and each including the first area and having a size determined by the determination unit;
- and
- calculating an evaluation value of each of the processing units,
- wherein the evaluation value is a sum of a first evaluation value and a second evaluation value, the first evaluation value decreasing as an absolute value of the disparity amount of the processing unit is less, and the second evaluation value decreasing as a position of the processing unit on the display screen is closer to the position of the first area, and
- the selecting of the enlargement area includes at least one of the second areas that includes processing units having a smallest sum of the evaluation values.
