An image coding system converting apparatus is arranged by employing input means 102 for sequentially reading an input bit stream, a decoder unit 103 for decoding inputted data, a data buffer 104 for saving either non-compression image data or image data being decoded in a half way, an added information buffer 105 for saving either added information related to image data or added information related to a coding system, an encoder unit 106 for encoding the image data read out from the data buffer 104 with reference to the added information read out from the added information buffer 105, and output means 107 for outputting the image data encoded by the encoder unit 106. Accordingly, it is provided an image coding system converting apparatus, and an image coding system converting method, capable of converting an image coded by one image coding system into another image coding system in a high speed, while suppressing a deterioration of an image quality, and also to provide a recording medium for recording thereon a computer readable program capable of executing the image coding system converting method.
