More Information
Summary:A stereo video coding apparatus which codes, out of a first viewpoint video and second viewpoint video, at least a second image included in the second viewpoint video, and includes: a judgment unit and a selection unit which output one of a prediction image generated by applying motion compensation to the second viewpoint video and a prediction image generated by applying disparity compensation to the first viewpoint video, by selectively switching between the prediction images; a subtractor; an orthogonal transform unit; a quantization unit; and a control unit which determines a quantization step size to be used by the quantization unit. The control unit determines a quantization step size to be applied to the second image to be a value smaller than a quantization step size to be applied to a first image that is paired with the second image, when the judgment unit selects the prediction image generated by applying disparity compensation.
