Patent ID: 8508585

Claim:
A three-dimensional video reproduction apparatus which reproduces a three-dimensional video, said apparatus comprising: a video decoder which decodes a video stream to generate a right-eye video signal and a left-eye video signal which have a parallax with respect to each other; a graphics decoder which decodes a graphics stream to generate a right-eye graphics signal and a left-eye graphics signal which have a parallax with respect to each other; a synthesizing unit configured to synthesize the right-eye video signal and the right-eye graphics signal to generate a right-eye output signal, and synthesize the left-eye video signal and the left-eye graphics signal to generate a left-eye output signal; and an output unit configured to reproduce the three-dimensional video by alternately outputting the right-eye output signal and the left-eye output signal generated by said synthesizing unit, wherein said synthesizing unit is configured to: generate a common chrominance signal by biasing a synthesis ratio of the right-eye video signal and the right-eye graphics signal in favor of one of the right-eye video signal and the right-eye graphics signal, in a case where (i) adjacent two pixels in the right-eye output signal are represented by the common chrominance signal and (ii) one of the adjacent two pixels is generated using the right-eye video signal and the other one of the adjacent two pixels is generated using the right-eye graphics signal; and generate a common chrominance signal by biasing a synthesis ratio of the left-eye video signal and the left-eye graphics signal in favor of one of the left-eye video signal and the left-eye graphics signal, in a case where (i) adjacent two pixels in the left-eye output signal are represented by the common chrominance signal and (ii) one of the adjacent two pixels is generated using the left-eye video signal and the other one of the adjacent two pixels is generated using the left-eye graphics signal.
