Abstract

En fremgangsmåte for å fremvise et bilde på et display, særlig i et videokonferansesystem, omfatter de følgende trinn: å tilveiebringe et primærbilde; å tilveiebringe en observasjonsvinkel og en betrakter i forhold til nevnte display; å modifisere primærbildet som en funksjon av nevnte observasjonsvinkel, hvilket resulterer i et modifisert bilde; og å fremvise nevnte modifiserte bilde på nevnte display. Modifiseringen av bildet kan innbefatte en horisontal skalering av primærbildet, spesielt utstrekking av primærbildet med en ekstensjonsfaktor som er større for høyere observasjonsvinkler enn for mindre observasjonsvinkler, f.eks. i invers proporsjon til en cosinusfunksjon av observasjonsvinkelen. Dersom et multibetraktningsdisplay anvendes, kan primærbildet og det modifiserte bildet fremvises i ulike retninger, f.eks. til betraktere med ulike betraktningsvinkler i forhold til displayet.
