Abstract

a presente invenção apresenta a geração de uma imagem mostrada na tela para um painel de exibição (503) de uma tela autoestereoscópica que projeta a imagem mostrada na tela em uma pluralidade de cones de visão. uma fonte (803) fornece uma representação tridimensional de uma cena a ser exibida e um gerador (805) gera, a partir da representação, a imagem mostrada na tela. para cada pixel, o gerador (805) determina uma indicação da direção de ponto de vista da cena refletindo uma direção de ponto de vista para a cena em resposta a uma função de mapeamento de direção e uma indicação de direção de projeção do cone de visão refletindo uma direção de projeção para o pixel dentro dos cones de visão. a função de mapeamento de direção reflete uma relação entre as direções de projeção do cone de visão e as direções de ponto de vista da cena. o valor de pixel que corresponde à direção de ponto de vista é, então, gerado a partir da representação tridimensional. além disso, um processador (809) determina uma característica do observador; e um adaptador (811) para adaptar a função de mapeamento de direção em resposta à característica do observador.
