Apparatus and method for encoding to encode image data and image data of the progressive entanglement corresponding to image data, apparatus and method of decoding progressive, to decode the first coded data obtained by encoding image data, and if the progressive Gundos encoded data obtained by encoding image data of entanglement, and.Program executed by a computer.An apparatus for encoding to encode image data and image data of the progressive entanglement corresponding to these image data is progressive.Having a first unit configured to encode the encoding of the image composing the image data of the first bonding to generate coded data and decode and restore the first encoded data to generate image data compound.A processing unit on sample set to over sampled image data to generate compound generated image data having the same resolution as that of the image data is progressive.And a second coding unit configured to encode the image data constituting the image data to generate second encoded data using progressive image data generated as image data, predictive.
