Abstract

patente de invenção: dispositivo de processamento de imagem e método de processamento de imagem. a presente invenção refere-se a um dispositivo de processamento de imagem capaz de exibir uma imagem se aproveitando de um desempenho de reprodução de cor de um painel enquanto assegurando que uma cor seja exibida com base em dados de uma cor estendida quando dados inseridos que incluem os dados da cor estentida são supridos. uma primeira unidade de conversão de espaço de cor (122) converte os dados de imagem em um sistema colorimétrico rgb, o qual tem uma gama de cores mais larga do que um gama de cores de um painel de cristal líquido (14) em dados de imagem em um sistema colorimétrico xyz. uma unidade de conversão de hama de cores não linera tridimensional (123) executa a conversão sobre os valores de tristímulos do sinal xyz. nesse momento, os dados de imagem são classificados em quatro cores e convertidos respectivamente de modo que a primeira cor é exibida em uma cor precisa para os dados inseridos, a segunda cor é exiboda utilizando uma gama de cores de uma faixa predeterminada além da gama de cores do painel de cristal líquido (14), e a quarta cor é exibida em uma cor que corresponde a um limite da gama de cores do painel cristal líquido (14).
