Title
(EN) WEIGHTED MAPPING OF IMAGE DATA SAMPLES TO PIXEL SUB-COMPONENTS ON A DISPLAY DEVICE
(FR) PROJECTION PONDEREE D'ECHANTILLONS DE DONNEES D'IMAGES SUR DES SOUS-COMPOSANTS DE PIXELS DANS UN DISPOSITIF D'AFFICHAGE
Abstract
(EN) Methods and apparatus are disclosed for sampling image data (1400) and mapping the samples (R, G, B of Cl) to pixel sub-components which form a pixel element (R1-R6) of an LCD display (1402) so that each pixel sub-component has a different portion of the image (1400) mapped thereto and at least one of the pixel sub-components has two or more samples mapped thereto. The methods can be used with conventional color LCD displays that include pixels consisting of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The separately-controllable nature of individual RGB pixel sub-components is used to effectively increase a screen's resolution in one dimension. A scan conversion process maps samples (R, G, B of Cl) of the image data (1400) to individual pixel sub-components, including mapping two or more samples to at least one of the pixel sub-components. As a result, each of the pixel sub-components represents a different portion of the image (1400). The color values are independently generated for each of the red, green, and blue pixel sub-components based on different portions of the image, rather than the color values for the entire pixel being generated based on a single sample or the same portion of the image (1400).
(FR) L'invention se rapporte à des procédés et à des appareils permettant d'échantillonner des données d'images (1400) et de projeter les échantillons (R, G, B de C1) sur des sous-composants de pixels qui forment un élément pixel (R1-R6) d'un afficheur à cristaux liquides (LCD) (1402) de sorte qu'une partie différente de l'image (1400) est projetée sur un sous-composant de pixel donné et qu'au moins un des sous-composants de pixels présente au moins deux projections d'échantillons. Lesdits procédés peuvent être mis en oeuvre sur des afficheurs LCD couleur classiques qui comportent des pixels constitués de trois sous-éléments ou sous-composants rectangulaires rouge, vert et bleu, qui ne se chevauchent pas. La possibilité intrinsèque de commander séparément les sous-composants de pixel RGB individuels permet d'accroître la résolution d'un écran suivant une dimension. Un processus de conversion de balayage (914) projette les échantillons des données d'images (806) sur les sous-composants de pixels individuels, et permet notamment de projeter au moins deux échantillons sur au moins un des sous-composants de pixels. En conséquence, chacun des sous-composants de pixels permet de représenter une partie différente de l'image (1400). Les valeurs de couleur sont générées indépendamment pour chacun des sous-composants de pixels rouge, vert et bleu en fonction de différentes parties de l'image, plutôt que générées, pour le pixel dans sa totalité, en fonction d'un échantillon unique ou de la même partie de l'image (1400).
