In one embodiment, there is provided a moving image decoder for decoding a compression-coded moving image stream. The decoder includes: a deblocking filter configured to perform deblocking filter processing on each of frames to be decoded; a load detector configured to detect a magnitude of internal processing loads occurring inside a video player, including a processing load for decoding; a determination module configured to determine whether to bypass the deblocking filter processing, depending on the magnitude of the internal processing loads. The deblocking filter is configured to bypass the deblocking filter processing, if the magnitude of the internal processing loads is bigger than a threshold value and a processing subject block of the frame is decoded using inter-view prediction.

Moving image decoder and moving image decoding method

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.

Moving picture decoding device and moving picture decoding method

One embodiment provides a moving picture decoding device for decoding a compression-coded video stream, including: an inverse-quadrature-transformer/dequantizer configured to perform inverse-quadrature-transformation/dequantization processing on 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 detecting module is small; and a controller configured to control the inverse-quadrature-transformer/dequantizer so as to skip at least part of the inverse-quadrature-transformation/dequantization processing if the judging module judges that the magnitude of the apparatus processing load is not small.
