Title (EN) IMPROVEMENTS IN IMAGE FORMATION
(FR) AMÉLIORATIONS D'UNE FORMATION D'IMAGE
Abstract:
(EN) Embodiments of the invention provide a method of processing colour image data comprising receiving image data corresponding to a first and a second region of an image having colour information represented in a first colour space; converting the colour information of the image data from the first colour space to a second colour space, the mapping being arranged to substantially maintain a perceived colour of the colour information and to select a meta-brightness of the first and second regions; and outputting the image data having colour information in the second colour space.
(FR) Selon des modes de réalisation, l'invention concerne un procédé de traitement de données d'image en couleur consistant : à recevoir des données d'image correspondant à une première et à une seconde région d'une image présentant des informations de couleur représentées dans un premier espace de couleur ; à convertir les informations de couleur des données d'image d'un premier espace de couleur à un second espace de couleur, la mise en correspondance étant conçue pour maintenir sensiblement une couleur perçue parmi des informations de couleur et pour sélectionner une méta-luminosité parmi des première et seconde régions ; et à délivrer les données d'image présentant les informations de couleur dans le second espace de couleur.
