Abstract

L'invention concerne un procédé et un dispositif de reproduction d'une image dans lesquels une image originale 3 en couleur est balayée et le signal d'image originale analogique ainsi obtenu est subdivisé en des signaux d'image séparés qui sont ensuite mis sous forme numérique. L'un de ces signaux par exemple le signe de couleur grise ou de couleur verte, est alors mis en mémoire dans sa totalité, alors que les autres sont échantillonnés de manière régulière avant d'être mis en mémoire. Ensuite, les signaux sont lus dans la mémoire en lisant sans changement le premier signal, et en lisant les autres avec interpolation entre les valeurs en mémoire Les signaux de sortie sont alors utilisés pour enregistrer une image de reproduction 10.
