Abstract

a presente descrição refere-se a um dispositivo de codificação e a um método para codificação, e a um dispositivo de decodificação e a um método para decodificação que tornam possível para obter dados de imagem com profundidade e dados de imagem bidimensional para um ponto de visualização que corresponde a um método de geração de imagem de exibição prescrito, independente do ponto de visualização no momento da captura de imagem. a partir dos dados tridimensionais de um objeto de formação de imagem gerado a partir dos dados de imagem bidimensional para uma pluralidade de pontos de visualização, uma unidade de conversão gera os dados de imagem bidimensional para uma pluralidade de pontos de visualização que correspondem ao método de geração de imagem de exibição prescrito, e gera os dados de imagem com profundidade que expressam o local na direção da profundidade do objeto de formação de imagem para cada pixel. uma unidade de codificação codifica os dados de imagem com profundidade e os dados de imagem bidimensional gerados pela unidade de conversão. uma unidade de transmissão transmite os dados de imagem com profundidade e os dados de imagem bidimensional codificados pela unidade de codificação. esta descrição é aplicável, por exemplo, em um dispositivo de codificação ou congêneres.
