Abstract

"DISPOSITIVO E MéTODO DE EXIBIçãO DE IMAGEM". A presente invenção relaciona-se com um dispositivo e um método para exibir imagens. Para combater a cópia de imagens por uma câmara de vídeo em uma sala de cinema, é conhecido modular a luminância dos pixels de um padrão ao redor do valor a ser exibido para uma freqüência alta que torna o padrão invisível para o olho humano mas que gera artefatos na seqüência filmada pela câmara de vídeo. De acordo com a invenção, é proposto temporariamente modular o padrão somente nas áreas fixas (segundo plano ou cenas interiores) ou, onde apropriado, nas áreas com movimentos fracos. Assim, ao invés de degradar a imagem nas áreas com movimento pela aplicação junto às mesmas do processamento de modulação temporal, é tomada uma decisão de não temporariamente modular o padrão nestas áreas críticas.
