Patent ID: 7526134

Claim:
An image processing apparatus comprising: a decompressing unit to decompress image data having a first data compression format, the image data being formed as a code stream including a set of markers to indicate a beginning and an end of the code stream; an obtaining unit to obtain a second data compression format that is applicable for decompression by another image processing apparatus; a re-compressing unit to re-compress the decompressed image data with the second data compression format obtained by the obtaining unit; a transmitting unit to transmit the re-compressed image data to the other image processing apparatus; and a request receiving unit to receive a request from the other image processing apparatus requesting for the image data having the first data compression format; wherein the first data compression format is a JPEG 2000 format; wherein the re-compression of the decompressed image data is performed with a lossless compression scheme; wherein the lossless compression scheme is a JPEG/DPCM scheme; wherein the other image processing apparatus is operable to decompress JPEG compressed data but not to decompress JPEG 2000 compressed data.
