Patent ID: 7379498

Claim:
Apparatus for reconstructing an image from still image compressed data, comprising: a transcoder arranged to transcode the still image compressed data into a bit stream of moving picture compressed data, the bit stream of moving picture compressed data comprising MPEG data and comprising I pictures, the bit stream of moving picture compressed data not comprising P pictures and B pictures, the transcoder comprising a Huffman encoder, a prediction and quantizer module, a still image compressed data decoder and a stream construction module, the stream construction module being downstream of the Huffman encoder and multiplexing Huffman code with MPEG table values, the Huffman encoder being downstream of the prediction and quantizer module, the prediction and quantizer module being downstream of the still image compressed data decoder, the transcoder transcoding without performing a discrete cosine transform; and a second decoder arranged to generate the reconstructed image by decoding the bit stream of moving picture compressed data, wherein the still image compressed data comprises discrete cosine transformed data and wherein the second decoder is arranged to perform an inverse discrete cosine transform, and wherein the still image compressed data comprises EXIF data and wherein the bit stream of moving picture compressed data does not include MPEG-1 data.
