<p>Provided is a dynamic image reproduction device which enables inverse-direction reproduction of a dynamic image in a short time. The dynamic image reproduction device includes two decoders and an output buffer. During a stand-by mode, a controller successively reads out from an accumulation device, first encoded image data on the first GOP preceding the I picture of the specified GOP by one GOP and the following I picture of the specified GOP and causes a first decoder to decode the data. During decoding performed by one of the decoders, the controller successively reads out from the accumulation device, second encoded image data on up to the I picture of the specified GOP and the following second GOP and causes a second decoder to decode the data. Outputs from the first and the second decoder are written into the output buffer. Thus, upon start of the inverse-direction reproduction, decoded image data is promptly outputted from the output buffer to reproduce the dynamic image.</p> |
