A method for compressing/restoring image data free from degradation of image: quality caused by compression/decompression, a method for compressing image data at high compression ratio, and its restoring method are disclosed, in the image data compressing method, image elements contained in a digital image read from a sheet of paper are extracted (S02), each of the extracted image elements (51-53) is subjected to data compression by a compression method corresponding to the type of the image element (S03-S05), and the compressed image element data (54-56) are stored.

L'invention se rapporte à un procédé de compression/restauration de données d'images sans dégradation de la qualité des images provoquée par la compression/restauration, à un procédé de compression de données d'images avec un rapport de compression élevé, et au procédé de restauration correspondant. Selon le procédé de compression des données d'images, les éléments d'images contenus dans une image numérique lue à partir d'une feuille de papier sont extraits (S02), chacun de ces éléments d'image extraits (51-53) est soumis à une compression de données selon un procédé de compression correspondant au type de l'élément d'image (S03-S05), et les données d'éléments d'images comprimés (54-56) sont sauvegardées.
