Abstract

L'invention concerne un procédé et un appareil de balayage d'images. Elle se rapporte à un procédé qui comprend le balayage d'une matière de copie afin qu'il forme un signal de données lues qui est comprimé et conservé dans la mémoire d'un calculateur, d'autres données étant transmises directement au calculateur qui, après décompression de parties choisies des signaux mémorisés, transmet à un dispositif de balayage d'une surface d'écriture, des signaux représentant une combinaison des données reçues. Application à la fabrication automatique des clichés d'impression.A method and apparatus for scanning images is provided. It relates to a method which comprises scanning a copy material to form a read data signal which is compressed and stored in the memory of a computer, other data being transmitted directly to the computer which, after decompressing selected portions of the stored signals, transmits signals representing a combination of the received data to a device for scanning a writing surface. Application to the automatic manufacture of printing plates.
