Abstract

realce consciente de profundidade para vídeo estéreo. a presente invenção se refere a sistemas, métodos e dispositivos para realçar uma imagem. em alguns aspectos, um aparelho compreende uma unidade de memória configurada para armazenar uma imagem à esquerda e uma imagem à direita. a imagem à esquerda e a imagem à direita podem, cada uma, representar uma mesma cena a partir de um ponto de vista diferente. o dispositivo compreende ainda um codificador configurado para recuperar a imagem à esquerda e a imagem à direita a partir da unidade de memória. o codificador é configurado para determinar um mapa de profundidade com base em uma diferença de orientação espacial entre as imagens esquerda e direita. o dispositivo compreende ainda um processador acoplado ao codificador. o processador é configurado para identificar uma parte da imagem à esquerda ou direita selecionada por um usuário. o processador é ainda configurado para determinar uma região de realce em torno da parte selecionada pelo usuário com base no mapa de profundidade. o processador é ainda configurado para melhorar a região de realce.
