Abstract

To provide an image reproducing apparatus which requires a small amount of memory capacity in reverse reproduction. The apparatus has an analyzing unit for acquiring interrelation between a plurality of items of reference image data to be referred to during decode processing from control data with a stream of encoded data, a buffer unit, and a decoding unit. An accumulation control unit uses the interrelation information obtained in the analyzing unit to extract the plurality of items of reference image data from the stream and to temporarily accumulate the same in the buffer unit. A decode control unit sequentially outputs reproduced image data decoded in the decoding unit in reverse time series as a reverse reproduction.

Dependent claims

An image reproducing apparatus comprising:

an analyzing unit which acquires interrelation between a plurality of items of reference image data to be referred to during decode processing from control data with a stream of encoded data;
a buffer unit to temporarily accumulate the plurality of items of reference image data;
a decoding unit which processes the plurality of items of reference image data accumulated in the buffer unit according to a decoding procedure;
an accumulation control unit which extracts the plurality of items of associated reference image data from the stream and temporarily accumulates the same in the buffer unit by using the interrelation information obtained in the analyzing unit;
