Title (EN) CONVERSION OF A SUB-PIXEL FORMAT DATA TO ANOTHER SUB-PIXEL DATA FORMAT
(FR) CONVERSION DE DONNEES AUX FORMATS SOUS-PIXEL EN UN AUTRE FORMAT DE DONNEES SOUS-PIXEL
Abstract:
(EN) A method of converting a source pixel data of a first format for a display of a second format having a plurality of three-color pixel elements is disclosed. The method comprises determining implied sample areas [120] for each data point [122] of each color in the source pixel data of the first format. The resample areas [52] for each emitter of each color in the display is also determined. A set of fractions for each resample area [52] is formed. The denominators are a function of the resample area [52] and the numerators are the function of an area of each of the implied sample areas [120] that at least partially overlaps the resample areas [[52]. The data values for each implied sample area [120] is multiplied by its respective fraction and all products are added together to obtain luminance values for each resample area [52].
(FR) L'invention concerne un procédé de conversion de données de pixel source d'un premier format destiné à un affichage en un second format possédant plusieurs éléments de pixel trichrome. Ce procédé consiste à déterminer des zones d'échantillonnage implicite [120] pour chaque point de données [122] de chaque couleur dans les données de pixel source de premier format. Les zones de rééchantillonnage [52] sont également déterminées pour chaque émetteur de chaque couleur dans l'affichage. Un ensemble de fraction est formé pour chaque zone de rééchantillonnage [52]. Les dénominateurs sont une fonction de la zone de rééchantillonnage [52] et les numérateurs sont la fonction d'une zone de chacune des zones d'échantillonnage implicite [120] qui couvrent au moins en partie les zones de rééchantillonnage [52]. Les valeurs de données pour chaque zone d'échantillonnage implicite [120] sont multipliées par leur fraction respective et tous les produits sont ajoutés ensemble afin d'obtenir des valeurs de luminance pour chaque zone de rééchantillonnage [52].
