Abstract
One embodiment provides a moving picture decoding device for decoding a compression-coded moving picture stream, including: an inter-view predicting module configured to perform inter-view prediction processing on processing subject blocks of each frame to be decoded; a load detector configured to detect a magnitude of an apparatus processing load including a processing load for decoding; a judging module configured to judge whether the magnitude of the apparatus processing load detected by the load detector is small; and a controller configured to control the inter-view predicting module so as to cause simplification of the inter-view prediction processing if the judging module judges that the magnitude of the apparatus processing load is not small.

A moving picture decoding apparatus for decoding a compression-coded moving picture stream, comprising:
- an inter-view predicting module configured to perform an inter-view prediction processing on processing subject blocks of each frame to be decoded, the inter-view prediction processing includes a first inter-view prediction processing in which both of a vertical component and a horizontal component of an inter-view vector is processed with a first precision;
- and a second inter-view prediction processing in which the vertical component of the inter-view vector is processed with a second precision while the horizontal component thereof is processed with the first precision, the first precision being to a higher precision than the second precision;
- a load detector configured to detect an apparatus processing load;
- a judging module configured to judge whether the detected apparatus processing load is smaller than a given value;
- and
- a controller configured to control the inter-view predicting module to perform the first inter-view prediction processing if the judging module judges that the apparatus processing load is smaller than the given value, and
- to perform the second inter-view prediction processing if the judging module judges that the apparatus processing load is not smaller than the given value.
