An image decompression system comprises: a decoding element 2 including at least one decoding part for decoding an inputted compressed image by the same system as a coding system of the compressed image; a coding part 7 for encoding a decoded image, which has been decoded by the decoding part 7, to reproduce a compressed image; a compressed reference image storing part 9 for storing, as a reference image, the compressed image compressed by the coding part 7; and a first switching element 6 for selecting one of the decoded image outputted from the decoding part 3 and a decoded image decoded using a compressed reference image stored in the compressed reference image storing part 9. Thus, the memory capacity used for storing reference images can be greatly saved by compressing a decompressed image again by the same coding system regardless of the kind of image.
