Title (EN) DUAL-PATH FOVEATED GRAPHICS PIPELINE
(FR) PIPELINE GRAPHIQUE FOVÉAL À DOUBLE TRAJET
Abstract:
(EN) A foveated display system includes a rendering device including at least one graphics processing unit (GPU) to render a foveal region and a peripheral region of a first image, wherein the foveal region has a higher resolution than the peripheral region. The system further includes a display device coupled to the rendering device via at least one physical layer. The display device includes a pixel array and a display controller coupled to the pixel array. The display controller includes a scaling component to upscale the first peripheral region to generate a scaled first peripheral region and a blending component to blend the foveal region with the scaled first peripheral region to generate a second image.
(FR) L'invention concerne un système d'affichage fovéal comprenant un dispositif de restitution comprenant au moins une unité de traitement graphique (GPU) permettant la restitution d'une zone fovéale et d'une zone périphérique d'une première image, la zone fovéale présentant une résolution plus élevée que la zone périphérique. Le système comprend en outre un dispositif d'affichage couplé au dispositif de restitution par l'intermédiaire d'au moins une couche physique. Le dispositif d'affichage comprend un réseau de pixels et un contrôleur d'affichage couplé au réseau de pixels. Le contrôleur d'affichage comprend un composant de mise à l'échelle permettant la mise à l'échelle de la première zone périphérique permettant de générer une première zone périphérique mise à l'échelle et un composant de mélange permettant de mélanger la zone fovéale avec la première zone périphérique mise à l'échelle permettant de générer une seconde image.
