Abstract
(EN)
Provided is a technology which enhances the reproducibility of an original image in an image after a binarization process. This image data generation method is provided with: acquiring first image data having a gradation value for each pixel with respect to each color; and generating, on the basis of the first image data, second image data having a binarized gradation value for each pixel with respect to each color, wherein the generating of the second image data includes: selecting a first pixel from the first image data; and binarizing the gradation value of the first pixel by means of first binarization process according to a comparison result showing that the gradation value of the first pixel is larger than a first threshold, binarizing the gradation value of the first pixel by means of a second binarization process according to a comparison result showing that the gradation value of the first pixel is smaller than a second threshold, and binarizing the gradation value of the first pixel by means of a third binarization process according to a comparison result showing that the gradation value of the first pixel is equal to or smaller than the first threshold and equal to or larger than the second threshold.

L'invention concerne une technologie qui améliore la reproductibilité d'une image d'origine dans une image après un processus de binarisation. Ce procédé de génération de données d'image comprend : l'acquisition de premières données d'image ayant une valeur de gradation pour chaque pixel par rapport à chaque couleur; et la génération, sur la base des premières données d'image, des secondes données d'image ayant une valeur de gradation binarisée pour chaque pixel par rapport à chaque couleur, la génération des secondes données d'image comprenant : la sélection d'un premier pixel à partir des premières données d'image; et la binarisation de la valeur de gradation du premier pixel au moyen d'un premier processus de binarisation selon un résultat de comparaison montrant que la valeur de gradation du premier pixel est supérieure à un premier seuil, la binarisation de la valeur de gradation du premier pixel au moyen d'un second processus de binarisation selon un résultat de comparaison montrant que la valeur de gradation du premier pixel est inférieure à un second seuil, et la binarisation de la valeur de gradation du premier pixel au moyen d'un troisième processus de binarisation selon un résultat de comparaison montrant que la valeur de gradation du premier pixel est égale ou inférieure au premier seuil et égale ou supérieure au second seuil.
