Title (EN) ANTIALIASING SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE ANTI-CRENELAGE
Abstract: front page image
(EN)A system and method for improved antialiasing in video processing is described herein. Embodiments include multiple video processors (VPUs) in a system. Each VPU performs some combination of pixel sampling and pixel center sampling (also referred to as multisampling and supersampling). Each VPU performs sampling on the same pixels or pixel centers, but each VPU creates samples positioned differently from the other VPUs corresponding samples. The VPUs each output frame data that has been multisampled and/or supersampled into a compositor that composites the frame data to produce an antialiased rendered frame. The antialiased rendered frame has an effectively doubled antialiasing factor.
(FR)L'invention porte sur un système et un procédé anti-crénelage amélioré dans le traitement des vidéo. De tels systèmes comportent des processeurs vidéo multiples (VPU) assurant chacun certaines combinaisons d'échantillonnage de pixels et de centres de pixels (également dites de multi-échantillonnage et de super-échantillonnage) s'effectuant sur les mêmes pixels ou centres de pixels, mais les échantillons créés par un VPU étant placés différemment de ceux correspondant aux autres. Chacun des VPU transmet des données de cadre multi-échantillonnées et/ou super-échantillonnées à un composeur qui les compose pour produire un cadre anti-crénelé présentant un facteur d'anti-crénelage effectivement doublé.
