CA 2761974

Techniques for rendering at least one object into a stereoscopic image for a display device are provided. Perceptual depth data as a fraction of viewer distance for the object is received. This perceptual depth data can be normalized. A pixel separation offset for a particular display device is calculated from the perceptual depth data. Left and right eye images of the object are respectively inserted into the stereoscopic image with the pixel separation offset. For a specific embodiment, the object includes captioning to be inserted.

L'invention porte sur des techniques de restitution d'au moins un objet dans une image stéréoscopique pour dispositif d'affichage. On reçoit des données perceptuelles de profondeur en tant que fraction d'une distance d'observateur pour l'objet. On peut normaliser ces données perceptuelles de profondeur. On calcule un décalage de séparation de pixels pour un dispositif d'affichage particulier à partir des données perceptuelles de profondeur. On introduit respectivement des images de l'?il gauche et de l'?il droit de l'objet dans l'image stéréoscopique avec le décalage de séparation de pixels. Pour un mode de réalisation spécifique, l'objet comprend l'introduction d'un sous-titrage.
