Abstract
An object of this invention is to suppress discontinuity of a moving image as much as possible. In order to achieve this object, an image reproduction apparatus includes a buffer which temporarily stores an encoded image data stream, a buffer size setting circuit which sets the storage size of the buffer, a decoding time calculation circuit which calculates a decoding time at which the encoded image data stream is output from the buffer to a decoder, and a control circuit which controls to set the storage size of the buffer to at least twice the maximum value of a storage size required by an encoded data stream reproducible by the image reproduction apparatus, start fetching a second encoded image data stream in the buffer immediately after fetch of a first encoded image data stream in the buffer is ended, and calculate the decoding time of the second image data stream on the basis of a time when fetch of the first image data stream in the buffer is ended.
