Abstract: front page image
(EN)The present invention provides a rasterization method, comprising: segmenting a pixel at a position where a color jump occurs to obtain multiple sub-pixels with continuously and gradually changing colors; and rasterizing the sub-pixels respectively. The present invention provides a rasterization device, comprising: a segmentation module, for segmenting a pixel at a position where a color jump occurs to obtain multiple sub-pixels with continuously and gradually changing colors; and a rasterization module, for rasterizing the sub-pixels respectively. The present invention improves the rasterization speed and the image quality.
(FR)L'invention concerne un procédé de tramage consistant à segmenter un pixel à l'emplacement où un saut de couleur survient afin d'obtenir de multiples sous-pixels à couleurs se modifiant de manière continue et graduelle, et à segmenter respectivement les sous-pixels. L'invention concerne aussi un dispositif de tramage comprenant un module de segmentation destiné à segmenter un pixel à l'emplacement où un saut de couleur survient afin d'obtenir de multiples sous-pixels à couleurs se modifiant de manière continue et graduelle, ainsi qu'un module de segmentation destiné à segmenter respectivement chaque sous-pixel. L'invention permet donc d'améliorer la vitesse de segmentation et la qualité d'image.
