US 2013/0258053 A1 · THREE-DIMENSIONAL VIDEO ENCODING APPARATUS, THREE-DIMENSIONAL VIDEO CAPTURING APPARATUS, AND THREE-DIMENSIONAL VIDEO ENCODING METHOD

Abstract

A provided three-dimensional video encoding apparatus adaptively switches a method of setting a reference picture according to a parallax between right and left sides, thereby improving encoding efficiency. A parallax acquisition unit 101 calculates parallax information on a first viewpoint video signal and a second viewpoint video signal according to a parallax matching method or the like. A reference picture setting unit 102 determines, from the parallax information, reference picture setting information on the selection of the reference picture in the encoding of a picture to be encoded, and the allocation of a reference index to the reference picture. An encoding unit 103 compresses and encodes the image data of the picture to be encoded, according to reference picture selection information.

Dependent claims

A three-dimensional video encoding apparatus that encodes a first viewpoint video signal that is a video signal of a first viewpoint and a second viewpoint video signal that is a video signal of a second viewpoint different from the first viewpoint,

the three-dimensional video encoding apparatus comprising:
a parallax acquisition unit that obtains parallax information on a parallax between the first viewpoint video signal and the second viewpoint video signal;
a reference picture setting unit that sets a reference picture used for encoding the first viewpoint video signal and the second viewpoint video signal;
and
an encoding unit that encodes the first viewpoint video signal and the second viewpoint video signal to generate an encoded stream based on the reference picture set in the reference picture setting unit,
wherein when the second viewpoint video signal is encoded, the reference picture setting unit has a first setting mode of setting, as a reference picture, at least one of pictures included in the first viewpoint video signal and pictures included in the second viewpoint video signal, and a second setting mode of setting, as a reference picture, at least one of pictures included only in the second viewpoint video signal, and
the reference picture setting unit switches the first setting mode and the second setting mode in response to a change of the parallax information obtained in the parallax acquisition unit.
