Abstract:
1. A motion image processing apparatus for reproducing motion image data being compressed by a digital motion image compressing method for conducting an image compressing process by information in a frame, said motion image processing apparatus comprising: a frame separating part sequentially separating and outputting frame data forming said motion image data every one frame; a decoding part conducting a decoding process for the frame data output by said frame separating part; a frame buffer maintaining the frame data decoded by said decoding part and sequentially outputting from older frame data in a chronological order; an accumulated data volume detecting part detecting a first number of sets of the frame data maintained in the frame buffer, and obtaining a frame data number D of sets of the frame data possible to further store in the frame buffer; a quality parameter calculating part calculating a quality parameter used to determine a decode quality at the decoding process conducted by said decoding part, based on the frame data number D; and a decode quality updating part indicating said decoding part to update the quality parameter calculated by said quality parameter calculating part, wherein said quality parameter calculating part includes a first part determining the quality parameter as a predetermined quality value minus the frame data number D, when the frame data number D is smaller than the first threshold and greater than the second threshold (second threshold<D<first threshold).
